    Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used drugs in the world. While the role of NSAIDs as cyclooxygenase (COX) inhibitors is well established, other targets may contribute to anti-inflammation. Here we report caspases as a new pharmacological target for NSAID family drugs such as ibuprofen, naproxen, and ketorolac at physiologic concentrations both in vitro and in vivo. We characterize caspase activity in both in vitro and in cell culture, and combine computational modeling and biophysical analysis to determine the mechanism of action. We observe that inhibition of caspase catalysis reduces cell death and the generation of pro-inflammatory cytokines. Further, NSAID inhibition of caspases is COX independent, representing a new anti-inflammatory mechanism. This finding expands upon existing NSAID anti-inflammatory behaviors, with implications for patient safety and next-generation drug design. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2015-01-01

    Non-steroidal anti-inflammatory drugs (NSAIDs) are the most prescribed group of drugs in the world. They are used primarily for pain relief in chronic inflammatory joint disease and act by inhibiting enzymes COX1 and COX2 and ultimately preventing the production of active prostanoids which are required for the innate inflammatory pathway. The use of NSAIDs have been associated with the development of gastrointestinal (GI) symptoms ranging from simple dyspepsia to life threatening GI bleeds and perforations. The definition of dyspepsia has evolved over the years and this has hampered accurate studies on the prevalence of dyspepsia as different studies used varying criteria to define dyspepsia. It is now known that NSAIDs significantly increase the risk of dyspepsia.The risk of developing peptic ulcer disease vary with specific NSAIDs and dosages but there is no correlation between the symptoms of dyspepsia and underlying peptic ulcers. The pathogenesis of dyspepsia with NSAIDs is not completely understood. Peptic ulceration alone is not able to account for the majority of dyspepsia symptoms encountered by NSAIDs users. Erosive oesophagitis secondary to NSAIDs may be contributing factor to the prevalence of dyspepsia in NSAIDs users. Altered gut permeability and changes in gastric mechanosensory function due to NSAIDs may also be a contributory factor. Management of NSAID induced dyspepsia is involves a multipronged approach. Drug avoidance if possible would be ideal. Other options include using the lowest effective dose, changing to an NSAIDs with a safer GI risk profile, avoiding concurrent use with other NSAIDs or if the patient has a previous history of peptic ulcer disease, and co-prescribing with anti-secretory medications such as proton pump inhibitors. Eradication of Helicobacter pylori has a protective role against developing peptic ulcers and may also improve symptoms of NSAIDs induced dyspepsia.

    The use of analgesia has become standard, and appropriate, practice in avian medicine. As in mammals, pain control in avian patients is usually accomplished with opioids and nonsteroidal anti-inflammatory drugs (NSAIDs) used singly or in combination for a multimodal approach. Despite their usefulness, widespread use, and relative safety in clinical use, few controlled studies in birds have been conducted on efficacy, safety, and dosing. The guidelines for the use of NSAIDs in raptors and other birds have mainly been empirical. More recently, NSAIDs in free-living raptors have emerged as a major conservation issue with the discovery that diclofenac sodium was responsible for the population crash of three species of Gyps vultures in southern Asia. In this context, residues of veterinary NSAIDs in domestic animals are now considered environmental contaminants that can be significantly toxic to vultures and possibly other avian scavengers. Ironically, the disaster with Asian vultures has led to a considerable body of research on NSAIDs in raptors to the benefit of clinicians who now have scientific information available to help assess dosing, safety, toxicity, and pharmacokinetics of NSAIDs in their raptor patients.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) are one of the most frequently prescribed drugs for the treatment of sciatica. A previous Cochrane review on the efficacy of NSAIDs summarised findings for acute and chronic low back pain (LBP) and sciatica. This is an update of the original review (2008) focusing on people suffering from sciatica. To determine the efficacy of NSAIDs in pain reduction, overall improvement, and reported side effects in people with sciatica. We performed electronic searches up to 24 June 2015 in the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, PubMed, and two trials registers. We searched reference lists of included studies and relevant reviews on the topics for additional trials. We included randomised controlled trials (double-blind, single-blind, and open-label) that assessed the efficacy of NSAIDs in sciatica. We included all trials that compared NSAIDs to placebo, to other NSAIDs, or to other medication. Additional interventions were allowed if there was a clear contrast for the treatment with NSAIDs in the trial. Three review authors independently assessed the risk of bias and extracted the data. Where feasible we calculated pooled results using Review Manager 5.3. We reported pain relief outcomes using mean difference (MD) with 95% confidence intervals (95% CI). We used risk ratios (RR) with 95% CI to report global improvement of treatment, adverse effects, and additional medication. We performed a meta-analysis if possible. We assessed level of evidence using the GRADE approach. We used standard methodological procedures recommended by The Cochrane Collaboration. We included 10 trials reported in 9 publications (N = 1651). Only one trial out of 10 was assessed at low risk of bias. Five trials used the currently recommended daily dose for the drug, and two trials used lower daily doses available over the counter. Three trials investigated NSAIDs no longer approved for human use. The follow-up duration

    The chemical advances of the 20th century led to the synthesis of non steroidal anti-inflammatory drugs (NSAIDs), beginning from phenylbutazone and indomethacin and continuing with other new drugs, including ibuprofen, diclofenac, naproxen, piroxicam and, more recently, the highly selective COX-2 inhibitors (coxibs). This progress derived from the discovery of the mechanism of action of these drugs: the inhibition of synthesis of prostaglandins due to the cycloxigenase enzyme system, according to the experimental contributions of John R. Vane.

    To analyse the available evidence on cardiovascular safety of non-steroidal anti-inflammatory drugs. Network meta-analysis. Bibliographic databases, conference proceedings, study registers, the Food and Drug Administration website, reference lists of relevant articles, and reports citing relevant articles through the Science Citation Index (last update July 2009). Manufacturers of celecoxib and lumiracoxib provided additional data. All large scale randomised controlled trials comparing any non-steroidal anti-inflammatory drug with other non-steroidal anti-inflammatory drugs or placebo. Two investigators independently assessed eligibility. The primary outcome was myocardial infarction. Secondary outcomes included stroke, death from cardiovascular disease, and death from any cause. Two investigators independently extracted data. 31 trials in 116 429 patients with more than 115 000 patient years of follow-up were included. Patients were allocated to naproxen, ibuprofen, diclofenac, celecoxib, etoricoxib, rofecoxib, lumiracoxib, or placebo. Compared with placebo, rofecoxib was associated with the highest risk of myocardial infarction (rate ratio 2.12, 95% credibility interval 1.26 to 3.56), followed by lumiracoxib (2.00, 0.71 to 6.21). Ibuprofen was associated with the highest risk of stroke (3.36, 1.00 to 11.6), followed by diclofenac (2.86, 1.09 to 8.36). Etoricoxib (4.07, 1.23 to 15.7) and diclofenac (3.98, 1.48 to 12.7) were associated with the highest risk of cardiovascular death. Although uncertainty remains, little evidence exists to suggest that any of the investigated drugs are safe in cardiovascular terms. Naproxen seemed least harmful. Cardiovascular risk needs to be taken into account when prescribing any non-steroidal anti-inflammatory drug.

    Four commercial gel preparations of topical anti-inflammatory agents have been assessed in six animal models commonly used to determine the biological activity of non-steroidal anti-inflammatory agents for systemic administration. Only UV-induced erythema of the skin, adjuvant induced arthritis and the measurement of vascular permeability proved suitable for differentiation of the potency of the four topical agents. Carrageenin-induced paw oedema, the cotton pellet test and the assessment of the pain threshold according to Randall and Selitto were of little value. The effects of the gel preparation of diclofenac (CAS 15307-86-5) diethylammonium (Voltaren Emulgel) were comparable to two preparations containing 1% and 5% active ingredient, respectively. Gel 4 showed low overall activity. The experiments demonstrated that some of the models used for the assessment of anti-inflammatory agent for systemic administration proved suitable for the testing of topical preparations and that percutaneous absorption was insufficient to elicit anti-inflammatory effect in the animals at sites remote from the site of application.

    Pain from renal colic is often severe and incapacitating. Many patients require emergent hospitalization and aggressive analgesia to relieve such discomfort. For many years, the optimal analgesic strategy has been sought to manage such severe pain. One of the mainstays of therapy for acute renal colic is with non-steroidal anti-inflammatory drugs (NSAIDs). This paper reviews the mechanism by which NSAIDs allow pain relief in renal colic, the evidence for their use in this condition, and the use of NSAIDs combined with other agents in renal colic.

    Full Text Available This review summarizes the current use of non-steroidal anti-inflammatory drugs (NSAIDs in obstetrics, gynecology and infertility. These medications are commonly used in different fields of reproductive medicine, for pain management after operative procedures and to relieve dysmenorrhea. In addition to their analgesic effect, NSAIDs are helpful in the management of menorrhagia by decreasing menstrual blood loss. NSAIDs alleviate pain associated with medical abortion, assist in undertaking natural cycle in-vitro fertilization by preventing follicular rupture and reducing premature ovulation, and serve as tocolytics in preterm labor. New NSAIDs may have a growing role in management of women's health.

    Full Text Available Increasing evidence suggests that prostatic inflammation plays a key role in the development of prostate cancer. It remains controversial whether non-steroidal anti-inflammatory drugs (NSAIDs reduce the risk of prostate cancer. Here, we investigate how a previously reported inverse association between NSAID use and the risk of aggressive prostate cancer is modulated by variants in several inflammatory genes. We found that NSAIDs may have differential effects on prostate cancer development, depending on one’s genetic makeup. Further study of these inflammatory pathways may clarify the mechanisms through which NSAIDs impact prostate cancer risk.

    1990-10-01

    Helicobacter pylori is now recognized as a frequent cause of histological chronic gastritis, and this has radically changed our understanding of this common condition. In the light of these developments, the traditional view that non-steroidal anti-inflammatory drugs are one of the common 'environmental' causes of chronic gastritis has been re-examined. Gastric mucosal biopsies have been studied from 430 patients undergoing routine upper gastrointestinal endoscopy, 99 of whom had recently been taking non-steroidal anti-inflammatory drugs. No significant association was found between the use of these drugs and either the presence of chronic gastritis or the frequency of colonization with H. pylori, although there was a strong association (P less than 0.0001) between H. pylori and gastritis. Non-steroidal anti-inflammatory drugs appear, however, to modify the inflammatory process in the gastric body, leading to a lower frequency of atrophic gastritis (P less than 0.05). The majority of peptic ulcers were associated with H. pylori irrespective of non-steroidal anti-inflammatory drug use, but there was a higher frequency of H. pylori negative ulceration in the patients who had used these agents (P less than 0.04). Peptic ulceration was uncommon in the absence of either H. pylori or recent non-steroidal anti-inflammatory drug use.

In a randomized fashion, ten subjects were studied after indomethacin (100 mg), nabumetone (1 g) or no medication (control) administered orally at 22.00 hours on the day before each study day, and again at 8.00 hours upon arrival at the laboratory. Renal function was studied...... decreased the plasma renin concentration. Thus, during exercise, nabumetone may decrease the excretion of 6-oxo-PGF(1alpha) by inhibition of cyclo-oxygenase-1 or by inhibition of specific exercise-induced activation of cyclo-oxygenase-2, or both.

Over a range of temperature and moisture conditions extractable {sup 14}C-diclofenac residues decreased with half lives < 5 days. No extractable transformation products were detectable by HPLC. Diclofenac mineralization in the loam soil was abolished by heat sterilization. Addition of biosolids to sterile or non-sterile soil did not accelerate the dissipation of diclofenac. These findings indicate that diclofenac is readily biodegradable in agricultural soils.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are roughly divided into a low-dose aspirin group used for primary and secondary prevention of cardiovascular events and non-aspirin NSAIDs used for treatment of bone and joint diseases. Both cause gastrointestinal damage directly or indirectly. In the present study, we reviewed gastrointestinal damage due to non-aspirin NSAIDs with respect to the esophagus, stomach/duodenum, small intestine and colon. Damage due to NSAIDs occurs in all digestive tracts and since the analgesic effect of NSIADs hides subjective symptoms, the symptoms are often not treated until they are advanced to a serious state. Further, patients receiving NSAIDs are mostly elderly and have complications so that the onset of the conditions is serious and prevention is important. It is necessary to investigate a method that is effective for preventing damage for all digestive tracts and the mechanisms of damage must be understood for this reason.

    2014-01-01

    Non-steroidal anti-inflammatory drugs (NSAIDs) are used extensively for analgesic and antipyretic treatments. In addition, NSAIDs reduce the risk and mortality to several cancers. Their mechanisms in anti-tumorigenesis are not fully understood, but both cyclooxygenase (COX)-dependent and -independent pathways play a role. We and others have been interested in elucidating molecular targets of NSAID-induced apoptosis. In this review, we summarize updated literature regarding cellular and molecular targets modulated by NSAIDs. Among those NSAIDs, sulindac sulfide and tolfenamic acid are emphasized in this review because these two drugs have been well investigated for their anti-tumorigenic activity in many different types of cancer.

    Susceptibility to Helicobacter pylori infection is a poorly understood phenomenon. This study was undertaken to establish whether either smoking or chronic non-steroidal anti-inflammatory drug (NSAID) consumption might in some way predispose to H. pylori infection and hence lead to peptic ulceration. Serological evidence of H. pylori infection was assessed in 100 consecutive subjects receiving NSAIDs without any evidence of gastrointestinal upset and 100 matched controls. All subjects had a full assessment of their smoking habits. Sixty-three per cent of patients taking NSAIDs compared to 51% of controls had evidence of H. pylori infection (NS). Smoking habit also had no effect on H. pylori colonization. The ulcerogenic potential of NSAIDs and smoking does not appear to be mediated via a prediposition to H. pylori infection.

The objective of this Ph.d. thesis was to investigate whether the use of NSAIDs in the postoperative period increases the risk of AL, and investigate the effect on pathophysiological mechanisms. In order...... to achieve this, the following studies were performed. Study I was a retrospective, case-control study in 75 patients undergoing laparoscopic colorectal resection for colorectal cancer. 33 of these patients received the NSAID diclofenac in the postoperative period; the remaining 42 did not receive any NSAID......Anastomotic leakage (AL) is the most important and one of the most serious complications after colorectal resections with primary anastomosis. Any factors that contribute to increase the risk of AL should be identified and - if possible - eliminated. Non-steroidal anti-inflammatory drugs (NSAIDs...

    Non-steroidal anti-inflammatory drugs (NSAIDs) are the most numerous category of drugs sharing the same mechanism of action and therapeutic activities (anti-inflammatory, analgesic and anti-pyretic). Despite having similar efficacy for pain relieve, the different available NSAIDs show variability in its safety profile. The risk of gastrointestinal and cardiovascular complications varies depending on the dose of NSAID and also the presence of different risk factors. It is necessary, therefore, an individualized case assessment before establishing the indication of the best NSAID for each patient, taking account of the best gastroprotection strategy. Improved prescription and enhanced treatment adherence are central objectives to reduce NSAID-related complications. A recent consensus of the Spanish Association of Gastroenterology and the Spanish societies of Cardiology and Rheumatology intends to promote the rational use of NSAIDs according to new recent studies. This review provides additional aspects to facilitate the optimal decision-making process in the routine use of these drugs in clinical practice. Copyright © 2015 Elsevier España, S.L.U.

  19. Non-steroidal anti-inflammatory drugs in sports medicine: guidelines for practical but sensible use.

    Non-steroidal anti-inflammatory drugs (NSAID) are commonly used in sports medicine. NSAID have known anti-inflammatory, analgesic, antipyretic and antithrombotic effects, although their in-vivo effects in treating musculoskeletal injuries in humans remain largely unknown. NSAID analgesic action is not significantly greater than paracetamol for musculoskeletal injury but they have a higher risk profile, with side-effects including asthma exacerbation, gastrointestinal and renal side-effects, hypertension and other cardiovascular diseases. The authors recommend an approach to NSAID use in sports medicine whereby simple analgesia is preferentially used when analgesia is the primary desired outcome. However, based both on the current pathophysiological understanding of most injury presentations and the frequency that inflammation may actually be a component of the injury complex, it is premature to suppose that NSAID are not useful to the physician managing sports injuries. The prescribing of NSAID should be cautious and both situation and pathology specific. Both dose and duration minimisation should be prioritized and combined with simple principles of protection, rest, ice, compression, elevation (PRICE), which should allow NSAID-sparing. NSAID use should always be coupled with appropriate physical rehabilitation. NSAID are probably most useful for treating nerve and soft-tissue impingements, inflammatory arthropathies and tenosynovitis. They are not generally indicated for isolated chronic tendinopathy, or for fractures. The use of NSAID in treating muscle injury is controversial. Conditions in which NSAID use requires more careful assessment include ligament injury, joint injury, osteoarthritis, haematoma and postoperatively.

    Full Text Available   Background: Peritendinous adhesions after repairing an injury to the digital flexor tendons are a major problem in hand surgery. Non-steroidal anti-inflammatory drug therapy may affect tendon healing and the development of peritendinous adhesions. The aim of this study was to evaluate ibuprofen effect in patients function after flexor tendon surgical repair.   Method: Thirty-five patients, who had sharp-edge lacerations of hand-zone II requiring flexor tendons repair, participated in this randomized double-blind clinical trial study. The patients were randomly classified into two parallel and matched groups (21 patients in the intervention group and 14 patients in the control group. The groups were matched considering age, gender, and laceration size. The control group received a placebo with the same appearance and dosage. In the intervention group, ibuprofen was prescribed at a high dosage (2400 mg/day. The range of motion improvement rate of the involved fingers and the patients’ performance after their follow-up period were compared. Results: There was a statistically significant difference between the two groups for range of motion of the involved finger joints (P=0.03. According to the DASH score, there was a statistically significant difference between the final performance of the patients, such that it was 11±2.4 and 18.4±6.3 in the intervention and control groups, respectively (P=0.01. There was not any case of re-tear or need to re-operate in the intervention and control groups. Conclusion: Our findings reveal that ibuprofen with an anti-inflammatory dose was effective in improving the range of motion of the involved fingers joints after flexor tendon injury.

  5. Mechanisms of peroxisome proliferator activated receptor γ regulation by non-steroidal anti-inflammatory drugs

    Non-steroidal anti-inflammatory drugs (NSAIDs) display anti-inflammatory, antipyretic and analgesic properties by inhibiting cyclooxygenases and blocking prostaglandin production. Previous studies, however, suggested that some NSAIDs also modulate peroxisome proliferator activated receptors (PPARs), raising the possibility that such off target effects contribute to the spectrum of clinically relevant NSAID actions. In this study, we set out to understand how peroxisome proliferator activated receptor-γ (PPARγ/PPARG) interacts with NSAIDs using X-ray crystallography and to relate ligand binding modes to effects on receptor activity. We find that several NSAIDs (sulindac sulfide, diclofenac, indomethacin and ibuprofen) bind PPARγ and modulate PPARγ activity at pharmacologically relevant concentrations. Diclofenac acts as a partial agonist and binds to the PPARγ ligand binding pocket (LBP) in typical partial agonist mode, near the β-sheets and helix 3. By contrast, two copies of indomethacin and sulindac sulfide bind the LBP and, in aggregate, these ligands engage in LBP contacts that resemble agonists. Accordingly, both compounds, and ibuprofen, act as strong partial agonists. Assessment of NSAID activities in PPARγ-dependent 3T3-L1 cells reveals that NSAIDs display adipogenic activities and exclusively regulate PPARγ-dependent target genes in a manner that is consistent with their observed binding modes. Further, PPARγ knockdown eliminates indomethacin activities at selected endogenous genes, confirming receptor-dependence of observed effects. We propose that it is important to consider how individual NSAIDs interact with PPARγ to understand their activities, and that it will be interesting to determine whether high dose NSAID therapies result in PPAR activation.

    Human serum albumin (HSA) is the most abundant protein in plasma, which plays a central role in drug pharmacokinetics because most compounds bound to HSA in blood circulation. To understand binding characterization of non-steroidal anti-inflammatory drugs to HSA, we resolved the structure of diclofenac and HSA complex by X-ray crystallography. HSA-palmitic acid-diclofenac structure reveals two distinct binding sites for three diclofenac in HSA. One diclofenac is located at the IB subdomain, and its carboxylate group projects toward polar environment, forming hydrogen bond with one water molecule. The other two diclofenac molecules cobind in big hydrophobic cavity of the IIA subdomain without interactive association. Among them, one binds in main chamber of big hydrophobic cavity, and its carboxylate group forms hydrogen bonds with Lys199 and Arg218, as well as one water molecule, whereas another diclofenac binds in side chamber, its carboxylate group projects out cavity, forming hydrogen bond with Ser480. © 2015 John Wiley & Sons A/S.

    Full Text Available We report the detailed clinical course of a 47-year-old woman with aspirin-induced asthma in which non-steroidal anti-inflammatory drug (NSAID intolerance developed over a 3 year period. The patient had mild asthma and was admitted with a femoral fracture in August 1996. Although she was given NSAIDs, including rectal diclofenac and oral loxoprofen, there was no worsening of asthma. After discharge, she was followed as having NSAID-tolerant asthma. When she developed perennial rhinitis and anosmia subsequent to an upper respiratory tract infection, asthma control was well maintained. Later, she experienced three episodes of severe asthmatic attacks after intake of aspirin or ketoprofen. Thus, we investigated her NSAID tolerability in September 1999. Sodium tolmetin inhalation challenge demonstrated a positive reaction, leading to the diagnosis of aspirin-induced asthma. Open challenges with loxoprofen and diclofenac also provoked positive reactions. The present case illustrates the potential variability of aspirin-induced asthma. Aspirin or NSAIDs challenge tests should be performed when nasal symptoms, particularly anosmia, develop or worsen.

    Many individuals use cyclo-oxygenase inhibitors (COX-1 and COX-2 non-steroidal anti-inflammatory drugs) and antiplatelet medications on a regular basis. This is particularly true of the elderly, who are more prone to having osteoarthritis, rheumatoid arthritis, and cardiac disease. Some of these agents alter platelet function and may increase the risk of spinal/epidural hematoma formation if spinal axis anesthesia is utilized without following proper precautions. All anesthesiologists should be familiar with these agents and how they work. More importantly, they should be familiar with the established guidelines set forth by the American Society of Regional Anesthesia (ASRA) [Regional anesthesia in the anticoagulated patient-defining the risk (2002); Reg. Anes. Pain Med. 28 (2003)172], the German Society of Anesthesiology and Intensive Care Medicine (DGAI) [Anaesthesiol. Intensivmed. 38 (1997) 623], and the Spanish Consensus Forum [Rev. Esp. Anesthesiol. Reanim. 48 (2001) 270]. This article explains the mechanism of action of each of the medications which alter platelet function, defines the risks of hematoma formation should the medication be inadvertently continued into the perioperative period, and provides guidelines and recommendations on how to manage each class of drug prior to the placement of spinal/epidural blocks.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed for the treatment of pain, inflamation and fever. They are usually well tolerated in healthy persons, but in patients with risk factors (advanced age, renal impairment, heart failure, liver disease, concurrent medications with antihypertensive drugs), NSAIDs can induce serious renal adverse effects. They include sodium and water retention with edema, worsening of heart failure, hypertension, hyponatremia, hyperkalemia, acute kidney injury, chronic kidney disease, renal papillary necrosis and acute interstitial nephritis. The majority of these adverse effects are due to the inhibition of prostaglandins synthesis and they are dose and duration-dependent. Acute forms of kidney injuries are transient and often reversible upon drug withdrawal. Chronic use of NSAIDs in some patients may result in chronic kidney disease. It is recommended that patients at risk should have preventative strategies in place, including the use of the "lowest effective dose" of NSAID for the "shortest possible time" and monitoring renal function, fluid retention and electrolyte abnormalities. Patients who are taking antihypertensive medications should be monitored for high blood pressure and the doses of antihypertensive medications should be adjusted if needed. In general, the combination of NSAIDs and angiotensin inhibitors should be avoided. Some other preventive measures are dietary salt restriction, use of topical NSAIDs/non-pharmacological therapies and use of calcium channel blockers for treating hypertension.

    Non-steroidal anti-inflammatory drugs (NSAIDs) have been widely used to treat inflammatory pain for decades. More recently, newer NSAIDs were developed to target the inducible isoform of cyclooxygenase (COX), COX-2, with the aim of reducing gastrointestinal toxicity. While the COX-2 selective inhibitors were effective in reducing pain and gastrointestinal harm, they soon were associated with an increased risk of adverse cardiovascular events. Initially, the view emerged that selective inhibition of COX-2, and sparing of COX-1, was responsible for the increased cardiovascular harm observed. However, as more data from different human populations has become available this view has begun to be challenged. This review examines the current understanding of the role of prostaglandins and COX-1 and COX-2, particularly in platelets, the vasculature, and the kidney together with an overview of the cardiovascular and renal safety of both traditional NSAIDs and COX-2 selective inhibitors. Available data from active comparator randomized controlled trials, including the data from the PRECISION trial investigating the long term cardiovascular safety of patients exclusively with elevated baseline cardiovascular risk, are presented. The data, when considered holistically, support the idea that all NSAIDs carry some level of cardiovascular risk, be they traditional NSAIDs or COX-2 selective agents. There is also some evidence of heterogeneity of effect with NSAIDs particularly in relation to effects on blood pressure, with no clear demarcation based on the degree of COX-2 selectivity.

    Eco-pharmacovigilance (EPV) is a practical and powerful approach to minimize the potential risks posed by pharmaceutical residues in environment. However, it is impracticable to practise rigorous and unitary EPV process for all the existing and new pharmaceuticals. Here, we focused on non-steroidal anti-inflammatory drugs (NSAIDs), and discussed the necessity and potential opportunities of practising EPV of NSAIDs. We found that the consumption of NSAIDs is huge and ubiquitous across the globe. NSAIDs were worldwidely reported as one of the most dominant and frequently detected groups in environmental matrices including wastewater, surface water, suspended solids, sediments, groundwater, even drinking water. Besides, there is definitive evidence for the adverse impacts of NSAID residues on scavenging birds and aquatic species. These data suggested the necessity of implementing EPV of NSAIDs. From the perspective of drug administration, we identified some things that can be done as management practice options for EPV implementation on NSAIDs. Copyright © 2017 Elsevier Ltd.

    Pharmaceutical pollutants are of significant effect on the environment, so that their treatments have been addressed in many studies. Activated carbon (AC) adsorbent shows best attraction for these compounds due to its unique characteristics represented by high capacity and porosity. In this article, the adsorption performance of AC towards non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, ketoprofen, naproxen, and diclofenac were reviewed. According to collected data, maximum adsorption capacities of 417, 25, 290, and 372 mg/g were obtained from Langmuir isotherm for these drugs, respectively. The values of 1/n for Freundlich isotherm were lower than unity for all studied drugs, confirming the nonlinear and favorable adsorption. In addition, kinetics data were well represented by the pseudo-second-order model and mechanism was not controlled by the pore diffusion step alone. AC adsorption demonstrated superior performance for all selected NSAIDs, thus being efficient technology for treatment of these pharmaceutical pollutants. Copyright © 2017 Elsevier Ltd.

    Multiple sclerosis is the most frequent demyelinating disease in the CNS that is characterized by inflammatory demyelinating lesions and axonal loss, the morphological correlate of permanent clinical disability. Remyelination does occur, but is limited especially in chronic disease stages. Despite effective immunomodulatory therapies that reduce the number of relapses the progressive disease phase cannot be prevented. Therefore, promotion of neuroprotective and repair mechanisms, such as remyelination, represents an attractive additional treatment strategy. A number of pathways have been identified that may contribute to impaired remyelination in MS lesions, among them the Wnt/β-catenin pathway. Here, we demonstrate that indometacin, a non-steroidal anti-inflammatory drug (NSAID) that has been also shown to modulate the Wnt/β-catenin pathway in colorectal cancer cells promotes differentiation of primary human and murine oligodendrocytes, myelination of cerebellar slice cultures and remyelination in cuprizone-induced demyelination. Our in vitro experiments using GSK3β inhibitors, luciferase reporter assays and oligodendrocytes expressing a mutant, dominant stable β-catenin indicate that the mechanism of action of indometacin depends on GSK3β activity and β-catenin phosphorylation. Indometacin might represent a promising treatment option to enhance endogenous remyelination in MS patients.

    The number of cases of drug-resistant Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), has risen rapidly in recent years. This has led to the resurgence in repurposing existing drugs, such as non-steroidal anti-inflammatory drugs (NSAIDs), for anti-TB treatment. Evidence from novel drug screening in vitro, in vivo, pharmacokinetic/pharmacodynamics analyses and clinical trials has been used for the preparation of this systematic review of the potential of NSAIDs for use as an adjunct in new TB chemotherapies. Certain NSAIDs have demonstrated inhibitory properties towards actively replicating, dormant and drug-resistant clinical isolates of M. tuberculosis cells. NSAIDs are a diverse class of drugs, which have reported off-target activities, and their endogenous antimicrobial mechanism(s) of action is still unclear. It is essential that clinical trials of NSAIDs continue, in order to assess their suitability for addition to the current TB treatment regimen. Repurposing molecules such as NSAIDs is a vital, low-risk strategy to combat the trend of rapidly increasing antibiotic resistance. © The Author 2016. Published by Oxford University Press.

    Iontophoresis is an important approach to improve transdermal drug delivery. However, The transdermal enhancement mechanism of iontophoresis was not well known. The relationship between the physicochemical properties of drugs and the transdermal enhancement effect of iontophoresis was revealed in this study. Non-steroidal anti-inflammatory drugs (NSAIDs) were used as the models, including aspirin, ibuprofen and indomethacin. Their oil-water partition coefficients were measured. The carbomer-based hydrogels of them were prepared. Iontophoresis significantly enhanced in vitro transdermal delivery across the rat skins. Strong lipophilicity could lead to high permeation of drugs. However, the dissociation extent (indicated as pKa) of drugs was the key factor to determine the transdermal enhancement effect of iontophoresis. The more dissociation the drugs were, the higher the transdermal enhancement effect of iontophoresis. The drug-loaded hydrogels combined with iontophoresis improved the treatment of rat raw's inflammatory syndrome. Iontophoresis significantly improved the drugs penetrating into the hypodermis, dermis and epidermis, more deeply than the application of drugs alone according to the experimental result of 5-carboxylfluorescein hydrogels. Iontophoresis led to the unordered arrangement of skin intercellular lipids, the significantly increased flowability and loose stratum corneum structure. Iontophoresis is a promising approach to improve transdermal drug delivery with safety and high efficiency. Copyright © 2014. Published by Elsevier B.V.

    Non-steroidal anti-inflammatory drugs (NSAIDs) have prohypertensive effects and blunt the effects of many antihypertensives. The mechanism of this interaction is still not understood enough. The objective of this investigation was to determine the level of prohypertensive effects of two NSAIDs (ibuprofen, piroxicam) and paracetamol, co-prescribed with two antihypertensive drugs (lisinopril + hydrochlorothiazide, amlodipine), and to improve the understanding of this interaction. A prospective clinical trial, conducted in a Croatian family practice, included 110 already treated hypertensive patients, aged 56-85 years; 50 control patients and 60 patients who were also taking NSAIDs for osteoarthritis treatment. The antihypertensive regimens remained the same during this study, while NSAIDs and paracetamol were crossed-over in three monthly periods. Blood pressure, body weight, serum creatinine, potassium, sodium, diuresis and 24 h urinary sodium excretion were followed-up. In the lisinopril/hydrochlorothiazide subgroup, both ibuprofen and piroxicam elevated mean arterial pressure by 8.9-9.5% (p NSAID's prohypertensive effects seem to be mostly due to vasoconstriction and, to a minor degree, to volume expansion, since no marked changes in body weight, urinary output, serum creatinine or serum/urinary electrolyte profile were observed.

  17. An update on the efficacy of non-steroidal anti-inflammatory drugs in Alzheimer's disease.

    2009-08-01

    Several epidemiological studies suggest that long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) may protect against Alzheimer's disease (AD), especially for patients carrying one or more epsilon4 allele of the apolipoprotein E. The biological mechanism of this protection is not completely understood and may involve inhibition of COX activity, inhibition of beta-amyloid(1-42) (Abeta42) production and aggregation, inhibition of beta-secretase activity, activation of PPAR-gamma or stimulation of neurotrophin synthesis. Unfortunately, long-term, placebo-controlled clinical trials with both non-selective and COX-2 selective NSAIDs in AD patients produced negative results. A secondary prevention study with rofecoxib in patients with mild cognitive impairment and a primary prevention study with naproxen and celecoxib in elderly subjects with a family history of AD were also negative. All these failures have diminished the hope that NSAIDs could be beneficial in the treatment of AD. It is hypothesized that the chronic use of NSAIDs may be beneficial only in the normal brain by inhibiting the production of Abeta42. Once the Abeta deposition process has started, NSAIDs are no longer effective and may even be detrimental because of their inhibiting activity on activated microglia of the AD brain, which mediates Abeta clearance and activates compensatory hippocampal neurogenesis.

    Evidence clearly shows a chemopreventive effect for aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) on colorectal cancer and probably other cancer types; however, data on the risk-benefit profile for cancer prevention are insufficient and no definitive recommendations can be made. Aspirin has emerged as the most likely NSAID for use in chemoprevention because of its known cardiovascular benefit and available safety and efficacy data. Other traditional NSAIDs, particularly sulindac, and selective COX-2 inhibitors are now given to patients at high risk of colorectal cancer, although these drugs do not provide cardioprotection. More studies of aspirin and cancer prevention are needed to define the lowest effective dose, the age at which to initiate therapy, the optimum treatment duration, and the subpopulations for which the benefits of chemoprevention outweigh the risks of adverse side-effects. Although it might be possible to answer some of these questions with longer follow-up of existing clinical trials, randomised controlled trials with new study designs will be needed. Future projects should investigate the effects of aspirin treatment on multiple organ systems. Cancers of interest are colorectal, breast, prostate, lung, stomach, and oesophageal. The main side-effect of aspirin is peptic ulcers; therefore coadministration of aspirin with a proton-pump inhibitor is an attractive option and is under investigation in the AspECT trial.

    AIM: To determine non-steroidal anti-inflammatory drug (NSAID) prescribing practices in a tertiary referral hospital. METHODS: A single time-point audit of drug kardexes and clinical notes of n = 388 patients on 2 July 2008 was carried out assessing demographics, gastrointestinal and coronary heart disease risk factors, renal function and co-prescribed medications. RESULTS: Fifty-seven of 388 (14.7%) hospital patients were on NSAIDs. Forty-nine were prescribed NSAID after admission. Nineteen (32.2%) were on regular NSAID (11\\/19 on PPI) and 38 patients were on PRN NSAID (12\\/38 on PPI). Seventeen of 49 patients were on other medications associated with gastrointestinal bleeding (10\\/17 were on PPI). Nineteen patients (33.3%) were >60 years. Eight patients had three or four risk factors for gastrointestinal bleeding; six were on PPI. Thirteen patients had two risks; 7 were on PPI. Six of 19 patients with one risk factor were on PPI. 40.3% had stage 2\\/3 chronic kidney disease. 35.1% had ischaemic heart disease. CONCLUSIONS: NSAIDs and PPIs are often prescribed inappropriately.

    Full Text Available Non-steroidal anti-inflammatory drug (NSAIDs induced enteropathy represents an important complication of one of the most commonly used drugs worldwide. Due to previous diagnostics difficulties the real prevalence of this disease was underestimated for a long time. The pathogenesis of NSAID-enteropathy is more multifactorial and complex than formerly assumed but has still not been fully uncovered. A combination of the local and systemic effect plays an important role in pathogenesis. Thanks to novel enteroscopy methods (wireless capsule endoscopy, double balloon enteroscopy, small bowel lesions are described in a substantial section of NSAID users although most are clinically asymptomatic. The other non-invasive tests (small bowel permeability, faecal calprotectin, scintigraphy using faecal excretion of 111-indium-labelled leukocytes etc. proposed for diagnostics are not generally used in clinical practice, mainly because of their non-specificity. Despite intensive research into possible treatment, the main measure for patients with NSAID-enteropathy is still withdrawal of NSAIDs. Double balloon enteroscopy plays an important role in the treatment of complications (bleeding, strictures.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for systemic control of acute and chronic pain and inflammation (Lin et ah, 2000:1129), but usage problems and side-effects that occur during the post-marketing phase of these drugs are well documented (Thiefin & Beaugerie, 2005:287). Following the demonstration of the value of anti-inflammatory therapy in diseases like rheumatoid arthritis (Boardman & Dudley Hart, 1967:268), new NSAIDs appeared on the market (Dieppe et al., 2004:...

    Membrane fusion is an essential process guiding many important biological events, which most commonly requires the aid of proteins and peptides as fusogenic agents. Small drug induced fusion at low drug concentration is a rare event. Only three drugs, namely, meloxicam (Mx), piroxicam (Px), and tenoxicam (Tx), belonging to the oxicam group of non steroidal anti-inflammatory drugs (NSAIDs) have been shown by us to induce membrane fusion successfully at low drug concentration. A better elucidation of the mechanism and the effect of different parameters in modulating the fusion process will allow the use of these common drugs to induce and control membrane fusion in various biochemical processes. In this study, we monitor the effect of lipid headgroup size mismatch in the bilayer on oxicam NSAIDs induced membrane fusion, by introducing dimyristoylphosphatidylethanolamine (DMPE) in dimyristoylphosphatidylcholine (DMPC) small unilamellar vesicles (SUVs). Such headgroup mismatch affects various lipid parameters which includes inhibition of trans-bilayer motion, domain formation, decrease in curvature, etc. Changes in various lipidic parameters introduce defects in the membrane bilayer and thereby modulate membrane fusion. SUVs formed by DMPC with increasing DMPE content (10, 20, and 30 mol %) were used as simple model membranes. Transmission electron microscopy (TEM) and differential scanning calorimetry (DSC) were used to characterize the DMPC-DMPE mixed vesicles. Fluorescence assays were used to probe the time dependence of lipid mixing, content mixing, and leakage and also used to determine the partitioning of the drugs in the membrane bilayer. How the inhibition of trans-bilayer motion, heterogeneous distribution of lipids, decrease in vesicle curvature, etc., arising due to headgroup mismatch affect the fusion process has been isolated and identified here. Mx amplifies these effects maximally followed by Px and Tx. This has been correlated to the enhanced

    Inflammation may play a role in pathogenesis of benign prostatic hyperplasia (BPH). However, the role of non-steroidal anti-inflammatory drugs (NSAIDs) as BPH risk factor is unclear. The objective of this study was to examine risk of BPH by NSAID use in a population-based cohort. A total of 74 754 Finnish men without previous BPH at baseline in 1996-1999 were linked to national medication reimbursement database for information on physician-prescribed NSAID purchases during 1995-2009. Information on BPH procedures and diagnoses was obtained from national Care Register for Health Care. Cox regression with adjustment for age and use of cholesterol-lowering, antidiabetic and antihypertensive medication, with NSAID use as time-dependent variable was used to analyse the risk of BPH surgery, medication use, and recorded diagnosis. Of the subjects 57 707 men (77.2%) used prescription NSAIDs. The risk of BPH was elevated among NSAID users compared to non-users: HR 2.04, 95% CI 1.97-2.10 for BPH medication use, HR 1.59, 95% CI 1.47-1.71 for recorded diagnosis and HR 1.61, 95% CI 1.49-1.74 for surgery. The risk increase correlated with duration of NSAID usage, less with annual dosage. Nevertheless, the risk increase was observed already at short-term and low-dosage use. NSAID use is associated with an increased risk of BPH. The association is affected by systematic differences by NSAID use as the risk increase was observed already at short-term use. Nevertheless, the association correlated with duration of use, suggesting that NSAID usage or the conditions indicating it may increase BPH risk. © 2017 Wiley Periodicals, Inc.

    To appraise whether adverse biological events following oral implant placement may be associated with perioperative use of non-steroidal anti-inflammatory drugs (NSAIDs). All patients treated in a university faculty postgraduate dental clinic between 1979 and 2012 that had experienced a failing and surgically removed dental implant (292 implants in 168 patients) were contacted to solicit additional information about their present dental and medical status and frequency of current and past use of NSAIDs. Potential associations between perioperative NSAIDs use and the occurrence of adverse biological events were explored by the use of 2 × 2 tables and two-tailed Fisher's exact tests. One hundred and four patients with initially 468 implants had experienced 238 implant failures, of which 197 were due to failing osseointegration (42%). Sixty of the participants, initially with 273 implants, had used NSAIDs perioperatively and experienced 44% implant failures, versus 38% in the non-NSAID cohort. The NSAID cohort experienced 3.2 times more cases of radiographic bone loss greater than 30% of the vertical height of their remaining implants and 1.9 times more cases of cluster failures, defined as failure of 50% or more of the implant(s) placed. Notwithstanding that a retrospective study design is open to potential bias, the current data indicate that dental implant osseointegration may be affected negatively by an inhibitory effect of NSAIDs on bone healing in vulnerable patients. Future and better clinical studies than the current should be designed to appraise more precisely the potential effects of NSAIDs on implant osseointegration in study populations that are not limited by stringent medical inclusion and exclusion criteria. © 2014 John Wiley & Sons A/S.

They remain a key component of the pharmacological management of acute and chronic pain. The COX-1 and COX-2 isozymes have different biological functions; analgesic activity is primarily (although not exclusively associated with inhibition of COX-2, while different side effects result from the inhibition of COX-1 and COX-2. All available NSAIDs, including acetaminophen and aspirin, are associated with potential side effects, particularly gastrointestinal and cardiovascular effects, related to their relative selectivity for COX-1 and COX-2. Since all NSAIDs exert their therapeutic activity through inhibition of the COX isozymes, strategies are needed to reduce the risks associated with NSAIDs while achieving sufficient pain relief. A better understanding of the inhibitory activity and COX-1/COX-2 selectivity of an NSAID at therapeutic doses, based on pharmacokinetic and pharmacodynamic properties (eg, inhibitory dose, absorption, plasma versus tissue distribution, and elimination, and the impact on drug tolerability and safety can guide the selection of appropriate NSAIDs for pain management. For example, many NSAIDs with moderate to high selectivity for COX-2 versus COX-1 can be administered at doses that maximize efficacy (~80% inhibition of COX-2 while minimizing COX-1 inhibition and associated side effects, such as gastrointestinal toxicity. Acidic NSAIDs with favorable tissue distribution and short plasma half-lives can additionally be dosed to provide near-constant analgesia while

    Colorectal cancer (CRC) is the third most common malignant neoplasm worldwide. Although conclusive evidence is still lacking, epidemiologic studies suggest that long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) has chemopreventive properties against CRC. Similarly, regular consumption of mesalazine, a drug structurally related to NSAIDs, seems to reduce the risk of CRC in patients with ulcerative colitis. These observations are supported by a large body of experimental data showing the ability of such drugs to inhibit multiple pathways that sustain colon carcinogenesis. This review summarizes the current information on the molecular mechanisms by which NSAIDs and mesalazine could interfere with CRC cell growth and survival.

    Anti-inflammatory, analgesic, and anti-pyretic activities of orally administered etofenamate, the diethylene glycol ester of flufenamic acid, were investigated in experimental animals. Against acetic acid-induced vascular permeability in mice and ultra-violet light-induced erythema in guinea pigs, etofenamate produced a dose related inhibition at doses of 40--320 mg/kg and 5--20 mg/kg, respectively. In rats, felt-pellet-induced granuloma formation and adjuvant-induced arthritis were significantly inhibited by repeated administration of etofenamate at doses of 20 mg/kg/day for 5 days and 40 mg/kg/day for 21 days, respectively. Etofenamate showed an inhibitory activity on the squeak response caused by flexing and extending the silver nitrate-induced arthritic joint in rats; and it produced a dose related anti-writhing activity at doses of 50--300 mg/kg and 10--80 mg/kg in mice and rats, respectively, in the acetic acid-induced writhing test. Etofenamate showed a significant anti-pyretic activity at doses of 0.2 mg/kg or more. These potencies of etofenamate were 0.5 to 1.6 times those of flufenamic acid. In particular, the anti-erythema, anti-arthritis, and anti-pyretic activities of etofenamate were approximately equivalent to or superior to those of flufenamic acid. From these results, it was suggested that etofenamate given orally, like other non-steroidal anti-inflammatory drugs, showed anti-inflammatory, analgesic, and anti-pyretic activities in experimental animals.

    Cataract is a leading cause of blindness worldwide. Cataract surgery is commonly performed but can result in postoperative inflammation of the eye. Inadequately controlled inflammation increases the risk of complications. Non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids are used to prevent and reduce inflammation following cataract surgery, but these two drug classes work by different mechanisms. Corticosteroids are effective, but NSAIDs may provide an additional benefit to reduce inflammation when given in combination with corticosteroids. A comparison of NSAIDs to corticosteroids alone or combination therapy with these two anti-inflammatory agents will help to determine the role of NSAIDs in controlling inflammation after routine cataract surgery. To evaluate the comparative effectiveness of topical NSAIDs (alone or in combination with topical corticosteroids) versus topical corticosteroids alone in controlling intraocular inflammation after uncomplicated phacoemulsification. To assess postoperative best-corrected visual acuity (BCVA), patient-reported discomfort, symptoms, or complications (such as elevation of IOP), and cost-effectiveness with the use of postoperative NSAIDs or corticosteroids.

    Traumatic corneal abrasions are relatively common and there is a lack of consensus about analgesia in their management. It is therefore important to document the clinical efficacy and safety profile of topical ophthalmic non-steroidal anti-inflammatory drugs (NSAIDs) in the management of traumatic corneal abrasions. To identify and evaluate all randomised controlled trials (RCTs) comparing the use of topical NSAIDs with placebo or any alternative analgesic interventions in adults with traumatic corneal abrasions (including corneal abrasions arising from foreign body removal), to reduce pain, and its effects on healing time.

    Lateral elbow pain, or tennis elbow, is a common condition that causes pain in the elbow and forearm. Although self-limiting, it can be associated with significant disability and often results in work absence. It is often treated with topical and oral non-steroidal anti-inflammatory drugs (NSAIDs). This is an update of a review first published in 2002 (search date October 11, 2012). To assess the benefits and harms of topical and oral NSAIDs for treating people with lateral elbow pain. We searched the Cochrane Central Register of Controlled Trials, MEDLINE, CINAHL, EMBASE and SciSearch up to October 11, 2012. No language restriction was applied. Studies were included if they were randomised or quasi-randomised controlled trials (RCTs or CCTs) that compared topical or oral NSAIDs with placebo or another intervention, or compared two NSAIDs in adults with lateral elbow pain. Outcomes of interest were pain, function, quality of life, pain-free grip strength, overall treatment success, work loss and adverse effects. Two review authors independently selected the studies for inclusion, extracted the data, and performed a risk of bias assessment. Fifteen trials, involving 759 participants and reporting 17 comparisons, were included in the review. Four new trials identified from the updated search were included, along with 11 of 14 trials included in the original review (three trials included in the previous review were found not to meet inclusion criteria). Of eight trials that studied topical NSAIDs (301 participants), five compared topical NSAIDs with placebo, one compared manipulative therapy and topical NSAIDs with manipulative therapy alone, one compared leech therapy with topical NSAIDs and one compared two different topical NSAIDs. Of seven trials that investigated oral NSAIDs (437 participants), two compared oral NSAIDs with placebo, one compared oral NSAIDs and bandaging with bandaging alone, three compared oral NSAIDs with glucocorticoid injection, one compared

    Anastomotic leakage (AL) is the most important and one of the most serious complications after colorectal resections with primary anastomosis. Any factors that contribute to increase the risk of AL should be identified and--if possible--eliminated. Non-steroidal anti-inflammatory drugs (NSAIDs) are often used for treating pain after surgical procedures, among these also colorectal resections. The objective of this Ph.d. thesis was to investigate whether the use of NSAIDs in the postoperative period increases the risk of AL, and investigate the effect on pathophysiological mechanisms. In order to achieve this, the following studies were performed. Study I was a retrospective, case-control study in 75 patients undergoing laparoscopic colorectal resection for colorectal cancer. 33 of these patients received the NSAID diclofenac in the postoperative period; the remaining 42 did not receive any NSAID. There were significantly more ALs among the patients receiving diclofenac (7/33 vs. 1/42, p=0.018). In uni- and multivariate logistic regression analyses, diclofenac was the only factor associated with increased AL rate. This study functioned as a hypothesis generating study and laid the ground for the subsequent studies. Study II was an experimental, randomized, case-control study in 32 Wistar rats. The rats had a colonic anastomosis performed and were randomized to diclofenac or placebo treatment. After three days, the rats were sacrificed and the anastomoses were harvested. First, the anastomotic strengths were tested by longitudinal; subsequently, the levels of the enzyme cyclooxygenase-2 (COX-2) in the anastomotic tissues were measured. There was no difference among the groups with regard to anastomotic strength, but the animals treated with diclofenac had significantly lower COX-2 levels (median (range) 1.30 (0.42-3.31) ng/mg vs. 2.44 (0.88 - 18.94) ng/mg, pNSAID treatment. Study III was also an experimental, randomized, case-control study. This time round, 60 Wistar

    Full Text Available Nicolás E Quintana,* Alejandro R Allocco,* Julia A Ponce,* Mauricio GB Magurno Instituto Santa Lucía, Paraná, Argentina *These authors contributed equally to this work Background: Cystoid macular edema (CME remains an important complication after cataract surgery. There is no consensus about how to prevent this frequent complication. The purpose of this study was to conceive an effective anti-inflammatory strategy using nonsteroidal anti-inflammatory drugs (NSAIDs together with regular treatment with corticosteroids to prevent CME and improve visual acuity after cataract surgery in patients without risk factors. Materials and methods: We searched the PubMed, Cochrane, and Google Scholar databases focused on prospective, controlled, randomized, double-blind clinical trials published in the last 10 years, with a minimum follow-up of 4 weeks. Results: A total of nine clinical trials, one systematic review, and two reviews satisfied our search criteria. Most studies highlighted that NSAIDs are as powerful as corticosteroids to diminish postoperative inflammation, and demonstrated an additional benefit when used in combination with standard corticosteroid postsurgical therapy. In addition, the use of NSAIDs in the perioperative period seems to significantly improve the outcome after surgery and helps prevent CME in low-risk patients. Conclusion: The prophylactic use of NSAIDs in combination with the standard postoperative steroid scheme appears to be a positive course of action for preventing CME after cataract surgery. We suggest a therapeutic scheme based on the administration of one drop four times a day, beginning the day before surgery and for 4 weeks after the procedure. It is also advisable to administer one drop every 15 minutes in the hour prior to surgery in order to obtain better anti-inflammatory efficacy.

    The cooperation of adaptive immunity with pharmacologic therapy influences cancer progression. Though non-steroidal anti-inflammatory drugs (NSAIDs) have a long history of cancer prevention, it is unclear whether adaptive immune system affects the action of those drugs. In present study, we revealed a novel immunological mechanism of sulindac. Our data showed that sulindac had substantial efficacy as a single agent against 4T1 murine breast cancer and prolonged the survival of tumor-bearing mice. However, in the athymic nude mice, sulindac treatment was ineffective. Further in vivo T cell subsets depletion experiments showed that CD8+ T lymphocytes deficiency reversed the anti-tumor effect of sulindac. In addition, sulindac significantly reduced M2 macrophages recruitment, cancer-related inflammation and tumor angiogenesis. Our results advance our understanding of the mechanisms of NSAIDs, and more importantly, this will provide insight into rational drug design or antitumor immunotherapy.

    In this contribution, we report on fast and ultrafast dynamics of a non-steroidal anti-inflammatory drug, piroxicam (PX), in methyl acetate (MAC) and triacetin (TAC), two solvents of different viscosities. The enol form of PX undergoes a femtosecond (shorter than 100 fs) electronically excited state intramolecular proton-transfer reaction to produce keto tautomers. These structures exhibit an internal twisting motion to generate keto rotamers in ˜2-5 ps, a time being longer in TAC. The transient absorption/emission spectrum is very broad indicating that the potential-energy surface at the electronically excited state is very flat, and reflecting the involvement of several coordinates along which the wavepacket of the fs-produced structures evolve.

    Full Text Available Lengthy, antimicrobial therapy targeting the pathogen is the mainstay of conventional tuberculosis treatment, complicated by emerging drug resistances. Host-directed therapies, including non-steroidal anti-inflammatory drugs (NSAIDs, in contrast, target host factors to mitigate disease severity. In the present Systematic Review, we investigate whether NSAIDs display any effects as therapy of TB and discuss possible mechanisms of action of NSAIDs as adjunctive therapy of TB. Ten studies, seven preclinical studies in mice and three clinical trials, were included and systematically reviewed. Our results point toward a beneficial effect of NSAIDs as adjunct to current TB therapy regimens, mediated by decreased lung pathology balancing host-immune reaction. The determination of the best timing for their administration in order to obtain the potential beneficial effects needs further investigation. Even if the preclinical evidence requires clinical evaluation, NSAIDs might represent a potential safe, simple, and cheap improvement in therapy of TB.

    Alzheimer's disease (AD) and Parkinson's disease (PD) are the most common neurodegenerative diseases with age as the greatest risk factor. As the general population experiences extended life span, preparation for the prevention and treatment of these and other age-associated neurological diseases are warranted. Since epidemiological studies suggested that non-steroidal anti-inflammatory drug (NSAID) use decreased risk for AD and PD, increasing attention has been devoted to understanding the costs and benefits of the innate neuroinflammatory response to functional recovery following pathology onset. This review will provide a general overview on the role of neuroinflammation in these neurodegenerative diseases and an update on NSAID treatment in recent experimental animal models, epidemiological analyses, and clinical trials.

    In continuation of our efforts to discover novel nitric oxide-releasing non-steroidal anti-inflammatory drugs (NO-NSAIDs) as potentially "Safe NSAIDs," we report herein the design, synthesis and evaluation of 21 new NO-NSAIDs of commonly used NSAIDs such as aspirin, diclofenac, naproxen, flurbiprofen, ketoprofen, sulindac, ibuprofen and indomethacin. These prodrugs have NO-releasing disulfide linker attached to a parent NSAID via linkages such as an ester (compounds 9-16), a double ester (compounds 17-24), an imide (compounds 25-30) or an amide (compounds 31-33). Among these NO-NSAIDs, the ester-containing NO-aspirin (9), NO-diclofenac (10), NO-naproxen (11), and the imide-containing NO-aspirin (25), NO-flurbiprofen (27) and NO-ketoprofen (28) have shown promising oral absorption, anti-inflammatory activity and NO-releasing property, and also protected rats from NSAID-induced gastric damage. NO-aspirin compound 25, on further co-evaluation with aspirin at equimolar doses, exhibited comparable dose-dependent pharmacokinetics, inhibition of gastric mucosal prostaglandin E(2) (PGE(2)) synthesis and analgesic properties to those of aspirin, but retained its gastric-sparing properties even after doubling its oral dose. These promising NO-NSAIDs could therefore represent a new class of potentially "Safe NSAIDs" for the treatment of arthritic pain and inflammation.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are emerging as novel chemopreventive agents against a variety of cancers owing to their capability in blocking the tumor development by cellular proliferation and by promoting apoptosis. Inflammation is principal cause of colon carcinogenesis. A missing link between inflammation and cancer could be the activation of NF-κB, which is a hallmark of inflammatory response, and is commonly detected in malignant tumors. Therefore, targeting pro-inflammatory cyclooxygenase enzymes and transcription factors will be profitable as a mechanism to inhibit tumor growth. In the present study, we have studied the role of various pro-inflammatory enzymes and transcription factors in the development of the 1,2-dimethylhydrazine dihydrochloride (DMH)-induced colorectal cancer and also observed the role of three NSAIDs, viz., Celecoxib, Etoricoxib and Diclofenac. Carcinogenic changes were observed in morphological and histopathological studies, whereas protein regulations of various biomolecules were identified by immunofluorescence analysis. Apoptotic studies was done by TUNEL assay and Hoechst/PI co-staining of the isolated colonocytes. It was found that DMH-treated animals were having an over-expression of pro-inflammatory enzymes, aberrant nuclear localization of activated cell survival transcription factor, NF-κB and suppression of anti-inflammatory transcription factor PPAR-γ, thereby suggesting a marked role of inflammation in the tumor progression. However, co-administration of NSAIDs has significantly reduced the inflammatory potential of the growing neoplasm. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

  7. Role of non-steroidal anti-inflammatory drugs on intestinal permeability and nonalcoholic fatty liver disease.

    The use of non-steroidal anti-inflammatory drugs (NSAIDs) is widespread worldwide thanks to their analgesic, anti-inflammatory and antipyretic effects. However, even more attention is placed upon the recurrence of digestive system complications in the course of their use. Recent data suggests that the complications of the lower gastro-intestinal tract may be as frequent and severe as those of the upper tract. NSAIDs enteropathy is due to enterohepatic recycling of the drugs resulting in a prolonged and repeated exposure of the intestinal mucosa to the compound and its metabolites. Thus leading to so-called topical effects, which, in turn, lead to an impairment of the intestinal barrier. This process determines bacterial translocation and toxic substances of intestinal origin in the portal circulation, leading to an endotoxaemia. This condition could determine a liver inflammatory response and might promote the development of non-alcoholic steatohepatitis, mostly in patients with risk factors such as obesity, metabolic syndrome and a high fat diet, which may induce a small intestinal bacterial overgrowth and dysbiosis. This alteration of gut microbiota may contribute to nonalcoholic fatty liver disease and its related disorders in two ways: firstly causing a malfunction of the tight junctions that play a critical role in the increase of intestinal permeability, and then secondly leading to the development of insulin resistance, body weight gain, lipogenesis, fibrogenesis and hepatic oxidative stress.

    Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) involves inflammation of the prostate and affects the quality of life of men of all ages. It is well reported in clinical studies that the treatment for CP/CPPS using nonsteroidal anti-inflammatory drugs (NSAIDs) produced favorable outcomes. However, currently, there are no guidelines on choice of the NSAIDs for the treatment of CP/CPPS. Therefore, in the current research study, we evaluated the prostate tissue penetration of four NSAIDs in rats to provide guidance on choice of NSAIDs for the treatment of CP/CPPS. Male Sprague-Dawley rats were administered orally with four NSAIDs viz. celecoxib, diclofenac, ibuprofen, and naproxen at 500 mg/kg dose. The animals were then sacrificed at various time points, and their prostate tissues were harvested. The NSAIDs were then extracted from the prostate tissues using liquid extraction technique, and their concentration in prostate tissue was quantified using high-performance liquid chromatography (HPLC). The prostate tissue penetration and related pharmacokinetic parameters were evaluated by non-compartmental analysis. The HPLC method for quantifying NSAIDs in prostate tissue resulted in single, sharp peaks without any interference and all validation parameters were within limits. Celecoxib showed the highest area under the curve (AUC) [146.50 ± 2.75 μg/mL*h] of all NSAID's. A two-factor analysis of variance (ANOVA) with replication indicated an overall statistically significant difference in the pharmacokinetic parameters for celecoxib, diclofenac, ibuprofen, and naproxen. This study for the first time reported the relative prostate tissue penetration of four NSAIDs. The pharmacokinetic data indicated that celecoxib has the highest penetration and retention in rat prostate tissues. Therefore, celecoxib may be considered as a better choice for the treatment CP/CPPS involving NSAIDs. © 2017 Wiley Periodicals, Inc.

    NSAIDs are known to be inhibitors of cyclooxygenase-2 (COX-2) accounting for their anti-inflammatory and anti-tumor activities. However, the anti-tumor activity cannot be totally attributed to their COX-2 inhibitory activity as these drugs can also inhibit the growth and tumor formation of COX-2-null cell lines. Several potential targets aside from COX-2 for NSAIDs have been proposed. 15-Hydroxyprostaglandin dehydrogenase (15-PGDH), a key prostaglandin catabolic enzyme, was recently shown to be a tumor suppressor. Effects of NSAIDs on 15-PGDH expression were therefore studied. Flurbiprofen, indomethacin and other NSAIDs stimulated 15-PGDH activity in colon cancer HT29 cells as well as in lung cancer A549 cells and glioblastoma T98G cells. (R)-flurbiprofen and sulindac sulfone, COX-2 inactive analogs, also stimulated 15-PGDH activity indicating induction of 15-PGDH is independent of COX-2 inhibition. Stimulation of 15-PGDH expression and activity by NSAIDs was examined in detail in colon cancer HT29 cells using flurbiprofen as a stimulant. Flurbiprofen stimulated 15-PGDH expression and activity by increasing transcription and translation and by decreasing the turnover of 15-PGDH. Mechanism of stimulation of 15-PGDH expression is not clear. Protease(s) involved in the turnover of 15-PGDH remains to be identified. However, flurbiprofen down-regulated matrix metalloproteinase-9 (MMP-9) which was shown to degrade 15-PGDH, but up-regulated tissue inhibitor of metalloproteinase-1 (TIMP-1), an inhibitor of MMP-9 contributing further to a slower turnover of 15-PGDH. Taken together, NSAIDs may up-regulate 15-PGDH by increasing the protein expression as well as decreasing the turnover of 15-PGDH in cancer cells. Copyright © 2011 Elsevier Inc. All rights reserved.

    Pain is a common feature of childhood and adolescence around the world, and for many young people, that pain is chronic. The World Health Organization (WHO) guidelines for pharmacological treatments for persisting pain in children acknowledge that pain in children is a major public health concern of high significance in most parts of the world. Views on children's pain have changed over time and relief of pain is now seen as important. In the past, pain was largely dismissed and was frequently left untreated, and it was assumed that children quickly forgot about painful experiences.We designed a suite of seven reviews in chronic non-cancer pain and cancer pain (looking at antidepressants, antiepileptic drugs, non-steroidal anti-inflammatory drugs, opioids, and paracetamol as priority areas) to review the evidence for children's pain using pharmacological interventions.As one of the leading causes of mortality and morbidity for children and adolescents in the world today, childhood cancer (and its associated pain) is a major health concern. Specific mortality and morbidity data relating to children are not currently identified. All childhood cancer rates are on the rise; for example, in the USA approximately 10,380 children aged under 15 years were expected to be diagnosed with cancer by the end of 2016. However, with survival rates also increasing, over 80% of paediatric cancer patients are expected to survive for five years or more, thus identifying the need to address pain management in this population.Cancer pain in infants, children, and adolescents is primarily nociceptive pain with negative long term effects. Cancer-related pain is generally caused directly by the tumour itself such as compressing on the nerve or inflammation of the organs. Cancer-related pain generally occurs as a result of perioperative procedures, nerve damage caused by radiation or chemotherapy treatments, or mucositis. However, this review focused on pain caused directly by the tumour

    The amyloid-beta (Abeta) peptides and in particular the longer, highly amyloidogenic isoform Abeta42 are believed by many to be the central disease-causing agents in Alzheimer's disease (AD). Consequently, academic and pharmaceutical laboratories have focused on elucidating the mechanisms of Abeta production and developing strategies to diminish Abeta formation for treatment or prevention of AD. The most substantial advances have been made with respect to inhibitors of the gamma-secretase enzyme, which catalyzes the final step in the generation of Abeta from the amyloid precursor protein (APP). Highly potent gamma-secretase inhibitors which suppress production of all Abeta peptides are available today. However, due to the promiscuous substrate specificity of gamma-secretase and its essential role in the NOTCH signaling pathway overt mechanism-based toxicity has been observed in preclinical studies of gamma-secretase inhibitors. For that reason, specific blockage of Abeta42 production might be preferable over non-discriminatory gamma-secretase inhibition but small molecule inhibitors of Abeta42 production have remained elusive until recently. This has changed with the discovery that certain non-steroidal anti-inflammatory drugs (NSAIDs) including ibuprofen possess preferential Abeta42-lowering activity. These compounds seem to offer a window of modulation where Abeta42 production is potently inhibited whereas processing of the NOTCH receptor and other gamma-secretase substrates remains unaffected. The Abeta42-lowering activity of NSAIDs is not related to inhibition of cyclooxygenases and can be dissociated from the anti-inflammatory properties of this class of drugs. Ongoing efforts concentrate on uncovering the mechanism of action and improving potency and brain permeability of Abeta42-lowering compounds. Hopes are high that in the near future this will lead to the development of clinically viable compounds which selectively target Abeta42 as a key molecule in the

    Directory of Open Access Journals (Sweden)

    Full Text Available BACKGROUND: Nonsteroidal anti-inflammatory drugs (NSAIDs are a family of COX1 and COX2 inhibitors used to reduce the synthesis of pro-inflammatory mediators. In addition, inflammation often leads to a harmful generation of nitric oxide. Efforts are being done in discovering safer NSAIDs molecules capable of inhibiting the synthesis of pro-inflammatory lipid mediators and nitric oxide to reduce the side effects associated with long term therapies. METHODOLOGY/PRINCIPAL FINDINGS: The analogue of arachidonic acid (AA, 2-hydroxy-arachidonic acid (2OAA, was designed to inhibit the activities of COX1 and COX2 and it was predicted to have similar binding energies as AA for the catalytic sites of COX1 and COX2. The interaction of AA and 2OAA with COX1 and COX2 was investigated calculating the free energy of binding and the Fukui function. Toxicity was determined in mouse microglial BV-2 cells. COX1 and COX2 (PGH2 production activities were measured in vitro. COX1 and COX2 expression in human macrophage-like U937 cells were carried out by Western blot, immunocytochemistry and RT-PCR analysis. NO production (Griess method and iNOS (Western blot were determined in mouse microglial BV-2 cells. The comparative efficacy of 2OAA, ibuprofen and cortisone in lowering TNF-α serum levels was determined in C57BL6/J mice challenged with LPS. We show that the presence of the -OH group reduces the likelihood of 2OAA being subjected to H* abstraction in COX, without altering significantly the free energy of binding. The 2OAA inhibited COX1 and COX2 activities and the expression of COX2 in human U937 derived macrophages challenged with LPS. In addition, 2OAA inhibited iNOS expression and the production of NO in BV-2 microglial cells. Finally, oral administration of 2OAA decreased the plasma TNF-α levels in vivo. CONCLUSION/SIGNIFICANCE: These findings demonstrate the potential of 2OAA as a NSAID.

    Introduction Acute pancreatitis (AP) is a common emergency presentation and can be disabling. There is significant morbidity and mortality associated with AP, and it places a considerable burden on the healthcare system. Non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to have a protective effect in some elective contexts. This retrospective study aimed to evaluate the effect of NSAIDs on the course of AP and the severity of the disease. Methods A retrospective analysis was carried out of 324 patients admitted as an emergency with a diagnosis of AP to two UK hospitals. Patients were divided into two groups: those already taking NSAIDs for other co-morbidities and those not taking NSAIDs. Variables compared included: admission to a high dependency or intensive care unit; pancreatic necrosis; pseudocyst development; need for surgery; serum inflammatory markers; modified early warning scores on days 1, 3 and 5; length of stay; and mortality. Results Patients not taking NSAIDs were more likely to have a C-reactive protein level of ≥150mg/l (p=0.007). Patients in the NSAID group experienced less pancreatic necrosis (p=0.019) and lower rates of pseudocyst formation (p=0.010). Other variables showed no difference between the two groups, specifically length of stay and mortality. Conclusions Routine NSAID use may exert a protective effect on the development of AP, its severity, and complications. Therapeutic use of NSAIDs in acute presentations with pancreatitis should be further evaluated.

    The combined preirradiation administration of indomethacin and cystamine was found to enhance synergistically the recovery of hemopoiesis in sublethally gamma-irradiated mice. This effect can be explained by a common operation of two mechanisms of radioprotection, i.e. of an increased survival of hemopoietic stem cells due to cystamine action and of stimulatory effects of indomethacin on the proliferation of surviving cells, mediated by the inhibition of prostaglandin synthesis. Attempts to prove such enhancement of protective effects on irradiated mice in terms of postirradiation lethality were unsuccessful. The reason seems to be the influence of toxic effects of the indomethacin-cystamine combination on the gastrointestinal tract. When using the less toxic combination, i.e. diclofenac and WR-2721, the additivity of protective effects is manifested even in the survival of lethally irradiated mice. The results suggest that under suitable conditions avoiding the unfavourable toxic effects, non-steroidal anti-inflammatory drugs can be successfully used with the aim to enhance the efficiency of sulfhydryl radioprotectors.

    The aim of the present investigation was to provide new insights on accumulation and possible adverse effects of various non-steroidal anti-inflammatory drugs (NSAIDs) in mussels, Mytilus galloprovincialis, exposed to an environmentally realistic concentration (0.5μg/L) of individual compounds, Acetaminophen (AMP), Diclofenac (DIC), Ibuprofen (IBU), Ketoprofen (KET) or Nimesulide (NIM). The measurement of drugs in mussel tissues was integrated with both functional alterations at cellular level and transcriptomic responses. Results indicated the capability of mussels to accumulate DIC and NIM, while AMP, IBU and KET were always below detection limit. A large panel of ecotoxicological biomarkers revealed the early onset of alterations induced by tested NSAIDs on immunological responses, lipid metabolism and DNA integrity. The gene transcription analysis through DNA microarrays, supported cellular biomarker results, with clear modulation of a large number of genes involved in the arachidonic acid and lipid metabolism, immune responses, cell cycle and DNA repair. The overall results indicated an ecotoxicological concern for pharmaceuticals in M. galloprovincialis, with transcriptional responses appearing as sensitive exposure biomarkers at low levels of exposure: such changes, however, are not always paralleled by corresponding functional effects, suggesting caution when interpreting observed effects in terms of perturbed cellular pathways. Fascinating similarities can also be proposed in the mode of action of NSAIDs between bivalves and vertebrate species. Copyright © 2016 Elsevier B.V. All rights reserved.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are known to antagonize the effects of antihypertensive drugs, and these associations can lead to an increase in arterial blood pressure. However, the impact of NSAIDs on hypertension treatment management in large-scale populations remains poorly evaluated. We examined whether the introduction of NSAID into the treatment regimen would induce an intensification of hypertension treatment (defined as the introduction of a new antihypertensive drug). We conducted a cohort study involving 5,710 hypertensive subjects included in the French health insurance system database who had been treated and stabilized with their antihypertensive therapy and not exposed to any NSAID between 1 April 2005 and 1 April 2006. The maximum follow-up duration was 4 years. Adjusted hazard ratios (HR) for hypertension treatment intensification were 1.34 [95 % confidence interval (CI) 1.05-1.71] for NSAIDs in general, 1.79 (95 % CI 1.15-2.78) for diclofenac and 2.02 (95 % CI:1.09-3.77) for piroxicam. There were significant interactions between NSAIDs and angiotensin converting enzyme inhibitors (ACEIs; HR 4.09, 95 % CI 2.02-8.27) or angiotensin receptor blockers (ARBs; HR 3.62, 95 % CI 1.80-7.31), but not with other antihypertensive drugs. Exposure to NSAIDs leads to an intensification of hypertension treatment, especially in patients treated with ACEIs or ARBs. Renin-angiotensin system blockers should be avoided whenever NSAIDs are prescribed.

    It has been established that the midbrain periaqueductal gray matter (PAG) and rostral ventro-medial medulla (RVM) are involved in the descending pain control system. The latter involves the midline nucleus raphe magnus (NRM) and adjacent reticular formation. These brain structures are is one of important parts of CNS circuit that controls nociceptive transmission at the level of spinal cord. Here we report that microinjection of commonly used non-steroidal anti-inflammatory drugs (NSAIDs), diclofenac, ketorolac, metamizol, and xefocam into the NRM produces strong antinociception which is mediated by the opioid mechanism. The experiments were carried out on experimental and control (saline) white albino male rats. Animals were implanted with a guide cannula in the NRM and tested for antinociception following microinjection of NSAIDs into the NRM in the tail flick (TF) and hot plate (HP) tests. The analysis of variance (ANOVA) with post-hoc Tukey-Kramer multiple comparison tests were used for statistical evaluation. The obtained data show that microinjection of these NSAIDs into the NRM produced antinociception as revealed by a latency increase in the tail-flick (TF) and hot plate (HP) latencies compared to the saline control microinjected into the same nucleus. Furthermore, we definitely showed that pre-treatment with opioid antagonist naloxone in the NRM diminishes NSAID-induced antinociception expressing in significant decrease in TF and HP latencies (PNSAIDs are mediated via an endogenous opioid system possibly involving the descending pain modulatory circuit.

    To date, genetic studies of hypersensitivity reactions to non-steroidal anti-inflammatory drugs (NSAIDs) have been carried out mainly in aspirin-induced asthma and to a lesser extent in chronic urticaria, with no studies in patients with acute urticaria (AU), the most common entity induced by these drugs. In this work, we analysed the association of common variants of 15 relevant genes encoding both enzymes and receptors from the arachidonic acid (AA) pathway with NSAID-induced AU. Patients were recruited in several Allergy Services that are integrated into the Spanish network RIRAAF, and diagnosed of AU induced by cross-intolerance (CRI) to NSAIDs. Genotyping was carried out by TaqMan allelic discrimination assays. A total of 486 patients with AU induced by CRI to NSAIDs and 536 unrelated controls were included in this large Spanish case-control study. Seven variants from 31 tested in six genes were associated in a discovery study population from Malaga (0.0003 ≤ p-value ≤ 0.041). A follow-up analysis in an independent sample from Madrid replicated three of the SNPs from the ALOX15 (rs7220870), PTGDR (rs8004654) and CYSLTR1 (rs320095) genes (1.055x10(-6) ≤meta-analysis p-value ≤ 0.003). Genetic variants of the AA pathway may play an important role in NSAID-induced AU. These data may help understand the mechanism underlying this disease. © 2012 Blackwell Publishing Ltd.

  2. [Direction of strategic use: a new classification of non-steroidal anti-inflammatory drugs based on reactivity with peroxidase].

    2013-01-01

      The pharmaceutical effects of non-steroidal anti-inflammatory drugs (NSAIDs) occur through the inhibition of prostaglandin H synthase (PGHS). Prostaglandin H2 is produced from arachidonic acid via peroxidase and cyclooxygenase cycles in PGHS. NSAIDs exhibit different levels of reactivity in these reaction cycles. To prevent the development of side effect while maintaining the beneficial effects of drugs, a therapeutic strategy should be used. A new classification of NSAIDs has been proposed based on reactivity to peroxidase. Class 1 includes the majority of NSAIDs, which react with horseradish peroxidase (HRP) compounds I and II. Also, their drugs exhibit spectral changes induced by PGHS peroxidase and diminished ESR signals of the tyrosyl radical of metmyoglobin. They reduce compounds I and II of HRP and scavenge tyrosyl radicals. The branched chain mechanism by which the porphyrin radical is transferred to the tyrosine residue of the protein might be blocked by these NSAIDs. Class 2 includes salicylic acid derivatives that react only with the porphyrin radical and do not react with HRP compound II (oxoferryl species). Class 3 includes aspirin, nimesulide, tolmetin, and arylpropionic acid derivatives, including ibuprofen and the coxibs such as celecoxib and rofecoxib, which are not substrates for HRP or PGHS peroxidase. It seems that the selectivity of NSAIDs to PGHS1 and PGHS2 depends on their reactivity with cyclooxygenase rather than with the peroxidase of PGHS. The best drug for each inflammatory disease should therefore be selected for therapy.

    Helicobacter pylori (H. pylori) infection and non-steroidal anti-inflammatory drugs (NSAIDs) or aspirin induce serious gastrointestinal ulcer and bleeding. Also both H. pylori infection and NSAIDs or aspirin use independently and significantly increase the risk of peptic ulcer and its complications. Interestingly, it has been reported that no evidence exists that reducing the dose or using modified release formulations such as enteric-coated of aspirin would reduce the incidence of ulcer bleeding. Selective COX-2 inhibitors use shows a low relative risk of ulcer bleeding than NSAIDs. However, when combined with aspirin, the differences between selective COX-2 inhibitors and NSAIDs tend to disappear. NSAIDs/aspirin dominantly develops multiple ulcers from the angulus to the antrum regardless of H. pylori infection. In contrast, the irregular shape of ulcer is more frequently detected in patients taking NSAIDs in comparison with H. pylori-associated ulcer, but the association was not seen in cases taking aspirin. This result indicates that the mechanism of ulcer formation may be different between NSAIDs and aspirin.

    Although epidemiological studies have shown that long-term treatment with non-steroidal anti-inflammatory drugs (NSAIDs) may protect against Alzheimer's disease (AD), the mechanism(s) by which NSAIDs reduce the risk of AD remain to be determined. As C. elegans possess neither inflammatory cells nor the arachidonate cascade, we could evaluate the effects of NSAIDs on amyloid beta (Abeta) deposition in the absence of immune cells using Abeta-transgenic C. elegans. For this purpose, we established a strain of Abeta-transgenic C. elegans in which thioflavin S-reactive deposits are reproducibly detectable by confocal microscopy. Among the NSAIDs examined, ibuprofen and naproxen reduced the number of thioflavin S-reactive deposits. Furthermore, ibuprofen and naproxen neither affect the thioflavin S binding to Abeta nor Abeta expression in transgenic C. elegans. These data suggest that ibuprofen and naproxen, the most frequently used NSAIDs for the treatment of AD, have an inhibitory effect on Abeta deposition that is independent of the arachidonate cascade and cellular immune systems.

    To investigate the efficacy and safety of rabeprazole under continuous non-steroidal anti-inflammatory drug (NSAID) administration for NSAID-induced ulcer in Japan. Subjects comprised patients undergoing NSAID treatment in whom upper gastrointestinal endoscopy revealed an ulcerous lesion (open ulcer) with diameter > or = 3 mm, who required continuous NSAID treatment. Endoscopies were performed at the start of treatment, during the treatment period, and at the conclusion (or discontinuation) of treatment. Findings were evaluated as size (maximum diameter) and stage based on the Sakita-Miwa classification. An ulcer was regarded as cured when the "white coating" was seen to have disappeared under endoscopy. As criteria for evaluating safety, all medically untoward symptoms and signs (adverse events, laboratory abnormalities, accidental symptoms, etc.) occurring after the start of rabeprazole treatment were handled as adverse events. Endoscopic cure rate in 38 patients in the efficacy analysis (endoscopic evaluation) was 71.1% (27/38). Among those 38 patients, 35 had gastric ulcer with a cure rate of 71.4% (25/35), and 3 had duodenal ulcer with a cure rate of 66.7% (2/3). Three adverse drug reactions were reported from 64 patients in the safety analysis (interstitial pneumonia, low white blood cell count and pruritus); thus, the incidence rate for adverse drug reactions was 4.7% (3/64). The treatment efficacy of rabeprazole for NSAID-induced ulcer under continuous NSAID administration was confirmed.

    Densities and viscosities of salicyl amide, salicylic acid, and acetyl salicylic acid (non-steroidal anti-inflammatory drugs) in two aprotic solvents namely, dimethyl sulfoxide and acetonitrile at T = (293.15, 298.15, 303.15, 308.15, 310.15, and 313.15) K have been determined in a molality range of (9.7 . 10{sup -3} to 33.3 . 10{sup -3}) mol . kg{sup -1}. The data have been used to calculate apparent molar volumes (V{sub {phi}}), and viscosity B-coefficients. The partial molar volumes and hydration numbers have been determined at different temperatures. The effect of temperature on the thermodynamic properties has been studied by determining partial molar expansibilities ({partial_derivative}V{sub m}{sup 0}/{partial_derivative}T) and Hepler's constant ({partial_derivative}{sup 2}V{sub m}{sup 0}/{partial_derivative}T{sup 2}). Free energies of activation for viscous flow of the solution were obtained by application of the transition state theory of solutions to the B-coefficient data and the corresponding activation enthalpies are reported.

    Piroxicam (Px) belongs to the oxicam group of the non-steroidal anti-inflammatory drugs (NSAIDs) and have been shown to exert chemopreventive and chemotherapeutic effects in animal models and cultured animal cells. However, little is known about the mode of action of Px and its cellular targets. We explored the role of Px, in triggering apoptosis and examined the involvement of upstream cellular mechanisms in apoptosis induction by Px. Our studies with human breast cancer cells MCF-7 show that Px induces reactive oxygen species (ROS) generation along with apoptotic cell death. ROS release lead to Akt activation. On evaluation it became evident that ROS mediated apoptosis induction was due to Akt activation (hyper phosphorylation). Silencing the expression of Akt using siRNA and a specific Akt inhibitor, triciribine further confirmed the findings. However Px failed to cause ROS generation, cell death or Akt phosphorylation in another human breast cancer cells MDA-MB-231 which is estrogen receptor negative and more aggressive compared to MCF-7 cells. This suggests that Px has cell type specific effects. Thus we revealed for the first time that Px can induce apoptosis by ROS mediated Akt hyperphosphorylation/activation.

    It is essential to provide complete information to patients using non-steroidal anti-inflammatory drugs (NSAIDs) because of the risk of side effects. Today, most healthcare professionals recommend and privilege oral information regarding NSAIDs. Evaluate the impact of three standardized NSAIDs information-delivery modalities on knowledge, anxiety and satisfaction of patients hospitalized in a Physical Medicine and Rehabilitation unit for debilitating and degenerative locomotor diseases. Randomized prospective study with an alternate month design. Two control groups were provided with only one type of information modality: written (information sheet) or oral (presentation). The intervention group received both modalities of information. The information included: the definition of NSAIDs, advantages and side effects, and practical advice regarding proper use. The main evaluation criterion was knowledge progression assessed by a specific questionnaire. Secondary criteria were anxiety evolution (STAI-Y questionnaire) and satisfaction related to the information delivered. One hundred and forty patients were included. Knowledge was improved in the three groups, with a greater score improvement in the group that received both modalities (P=0.05). No intergroup difference was noted on anxiety or satisfaction. Associating both information-delivery modalities (written+oral) contributes to improving knowledge but does not seem to have an impact on the anxiety of patients treated with NSAIDs for their degenerative locomotor disease. Using standardized information sheets with a validated content could help pharmacists in their role as healthcare education provider and effectively complement the information delivered orally.

    Stearic acid-based solid lipid nanoparticles (SLNs) were prepared using the microwave assisted one-pot microemulsions procedure pioneered by our group. In this study, non-steroidal anti-inflammatory drugs (NSAIDs) including indomethacin, ketoprofen and nimesulide were selected as ideal "test" drugs, based on their poor water solubility. The model drugs were incorporated within the SLNs by the microwave-assisted procedure at the time of SLN production. The microwave-produced drug-loaded SLNs were evaluated in terms of their physicochemical characteristics, drug release behavior and their uptake into against A549 cell line (human lung epithelial cells). The microwave-produced drug-loaded SLNs had a small particle size distribution, negative zeta potential and high encapsulation efficiency. The drug release studies were consistent with a core-shell structure of SLNs (probably a drug-loaded shell) which results in biphasic drug release from the SLNs. The drug release kinetics suggested a good fit of the release data to the Makoid-Banakar model and was governed by Fickian diffusion. The drug-loaded SLNs showed concentration-dependent cytotoxicity and reduced IL-6 and IL-8 secretion in lipopolysaccharide-induced cells. All of the above findings suggest that the microwave-produced SLNs could be promising drug carriers of NSAIDs and will further facilitate their development for topical, oral and/or nasal administration.

    Until recently, adverse effects of non-steroidal anti-inflammatory drugs (NSAIDs) on osseointegration of dental implants were unknown. Hence, this study investigated the short- and long-term effects of a 7-day regimen of parecoxib and diclofenac sodium on osseointegration of dental implants in calvarial bone. Eighteen New Zealand White rabbits were randomly allocated into three groups (each n = 6): Control group with no postoperative pain killers (Group A), diclofenac group (Group B) and parecoxib group (Group C). In each animal, one dental implant was placed into the calvarial bone (total n = 18). Three rabbits from each group were sacrificed in Week 4. The other three rabbits from each group were sacrificed in Week 12 postoperatively. The implant together with the calvarial bone and dura mater was harvested and subjected to micro-computed tomography (micro-CT) and histomorphometric analysis. Quantitative analysis of micro-CT data and histomorphometric data neither revealed any statistically significant (P ≤ 0.05) differences between the three different groups related to osseointegration nor between different time points of observation. In rabbits, a 7-day regimen of appropriate doses of diclofenac sodium and parecoxib did not adversely affect osseointegration of dental implants and bone healing in calvaria, neither short nor long term (12 weeks). © 2014 John Wiley & Sons A/S.

    Full Text Available Recent 16S ribosomal RNA gene (rRNA molecular profiling of the stomach mucosa revealed a surprising complexity of microbiota. Helicobacter pylori infection and non-steroidal anti-inflammatory drug (NSAID use are two main contributors to gastritis and peptic ulcer. However, little is known about the association between other members of the stomach microbiota and gastric diseases. In this study, cloning and sequencing of the 16S rRNA was used to profile the stomach microbiota from normal and gastritis patients. One hundred and thirty three phylotypes from eight bacterial phyla were identified. The stomach microbiota was found to be closely adhered to the mucosa. Eleven Streptococcus phylotypes were successfully cultivated from the biopsies. One to two genera represented a majority of clones within any of the identified phyla. We further developed two real-time quantitative PCR assays to quantify the relative abundance of the Firmicutes phylum and the Streptococcus genus. Significantly higher abundance of the Firmicutes phylum and the Streptococcus genus within the Firmicutes phylum was observed in patients with antral gastritis, compared with normal controls. This study suggests that the genus taxon level can largely represent much higher taxa such as the phylum. The clinical relevance and the mechanism underlying the altered microbiota composition in gastritis require further functional studies.

    Non-steroidal, anti-inflammatory drugs (NSAIDs) are widely used pharmaceutical products with analgesic and anti-inflammatory effects that are consistently detected in municipal wastewater systems and in municipal biosolids. Land application of biosolids and irrigation with reclaimed wastewater introduces these compounds into agricultural environments, which is an emerging issue of concern for ecosystem health. In this study, the sorption-desorption behaviour of four commonly consumed NSAIDs, including naproxen (NPX), ibuprofen (IBU), ketoprofen (KTF), and diclofenac (DCF), was examined in a loam textured soil exposed to either an individual-compound or a mixture of the four NSAIDs. The proportion of NSAIDs adsorbed to the soil in the mixture-compound system was 72%, 55%, 50% and 45%, for diclofenac, naproxen, ketoprofen, and ibuprofen, respectively, and differed slightly from the individual compound adsorption. Diclofenac displayed strong sorption and low desorption in both the individual-compound and mixture-compound systems. Naproxen and ibuprofen exhibited significant differences between the adsorption isotherms of the individual-compound and mixture-compound systems. Results of this study highlight differences in the sorption behaviour of NSAIDs, when present as mixtures, possibly through multilayer bonding effects or complexation with cationic metals or organo-clays from the soil. Soil organic matter (SOM) may have played a role in determining some of the interactions between the compounds but other factors associated with the mixture-compound system, such as cation bridging or multilayer cooperative adsorption. Desorption data suggests that the mechanisms involved in binding NSAIDs to the soil surface are also influence by the presence of other compounds in a mixture. A reduction in desorption was observed for all four NSAIDs in the mixture-compound system relative to the individual-compound system, but were greatest for naproxen and ibuprofen. The sorption

    The inflammatory process plays an important role in sulfur mustard (HD) injury and HD pathogenesis, suggesting that anti-inflammatory treatments applied as soon as possible following HD injury may reduce tissue damage and accelerate healing. This study used the HD dermal weanling swine model to investigate the efficacy of two non-steroidal anti-inflammatory drugs, capsaicin and diclofenac, when applied in combination with the steroid, clobetasol. The therapeutic regimen was also investigated with respect to initiation of treatment post-exposure, frequency and duration. Yorkshire-cross pigs were randomly assigned to experimental groups, corresponding to all combinations of treatment (capsaicin with clobetasol or diclofenac with clobetasol), onset time (1, 2 or 4 h post-exposure), treatment duration (1, 3 or 5 days) and frequency of applications (2, 3 or 4 per day). For each animal, two sites on the ventral abdomen were exposed to 400 μL of neat HD for 8 min to achieve superficial dermal (SD) lesions and two sites were exposed to 400 μL neat HD for 30 min to achieve deep dermal (DD) lesions. Each treatment regimen was tested against a SD and a DD injury. Untreated SD and DD lesion sites served as within-animal controls. Assessments, up to one week post-challenge, included digital photographs, clinical assessments (lesion size measurements and modified Draize scoring), transepidermal water loss (TEWL), reflectance colorimetry and histopathologic evaluations that included an estimate for depth of injury and wound healing parameters. Diclofenac plus clobetasol treatment resulted in significant reductions in lesion contracture and modified Draize scores, increased barrier function (decreased TEWL), and increased healing as determined by histopathology for both SD and DD injury when compared with untreated sites and sites treated with capsaicin plus clobetasol. An increased duration of treatment from 1 to 5 days was most commonly associated with decreased

    Aspirin and non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs) are preventive against cardiovascular disease (CVD) and several cancer types, but long-term use has been associated with significant health risks, resulting in conflicting recommendations on NSAID use for prevention of CVD and cancer. Previous research indicates that aspirin use increases with age and CVD risk factors and that a large percentage of the US population regularly use analgesics, including NSAIDs, but there has not been a recent, in-depth assessment of NSAID use prevalence, changes in use over time or predictors of NSAID use in the USA. We used the cross-sectional, National Health And Nutrition Examination Survey (NHANES) from 1988 to 1994 and three continuous cycles (1999-2004) to assess regular NSAID use prevalence, changes over time and predictors of regular NSAID use. Overall, regular NSAID use increased over time and varied by demographic features. Participants over 60 years of age, women, participants with high body mass index, increased waist circumference or heart disease were significantly more likely to be regular NSAID users. By contrast, non-Hispanic African American and Mexican American participants were significantly less likely to regularly use NSAIDs. This study uses a nationally representative data set (NHANES) to provide an exploration of regular NSAID use patterns over time, highlighting several demographic, lifestyle and clinical conditions associated with regular NSAID use. Understanding who is likely to regularly use NSAIDs enables more targeted messaging both for increasing the preventive benefits and for limiting the toxicities associated with regular use of NSAIDs.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are frequently prescribed for musculoskeletal pain and inflammatory conditions. A better understanding of patient information seeking behavior can help bridge the gap between patient knowledge and health care resources. This study examines the primary sources of NSAID risk information and the associations with patient socio-demographic factors. A cross-sectional survey analysis of patients on prescription NSAIDs (n=220) seen by primary care physicians in Alabama. Bivariate and multivariable, multinomial logistic regression analyses were conducted to evaluate the associations among primary NSAID risk information sources used with patient socio-demographic factors. The primary patient source of information on NSAID risks was physician (57.3%), followed by internet (16.8%), pharmacist (16.4%), and other sources, such as nurses and family/friends (9.6%). Compared to people who use the internet as a primary source of NSAID risk information, patients who were Black/African-American (p=0.002) and 65 years of age or older (p=0.009) were more likely to use a physician. Older patients were also more likely to use a pharmacist (p=0.008) than the internet. In contrast, females (p=0.032) were less likely to use the pharmacist compared to the internet (p=0.032). Patients obtain information from a variety of sources, but primarily from health care providers. While the internet is a fast growing source of health information, socio-demographic disparities in internet use for seeking information exist. Health care providers should be aware of their patient preferences for information sources on medication risks to meet the age, race, and gender need differences of all patients.

    In the recent clinical guideline for acute lateral ankle sprain, the current best evidence for diagnosis, treatment and prevention strategies was evaluated. Key findings for treatment included the use of ice and compression in the initial phase of treatment, in combination with rest and elevation. A short period of taking non-steroidal anti-inflammatory drugs (NSAIDs) may facilitate a rapid decrease in pain and swelling can also be helpful in the acute phase. The objective was to assess the effectiveness and safety of oral and topical NSAID in the treatment for acute ankle sprains. Randomised controlled trials comparing oral or topic NSAID treatment with placebo or each other were included. Primary outcome measures were pain at rest or at mobilisation and adverse events. Trials were assessed using the Cochrane risk of bias tool. Twenty-eight studies were included, and 22 were available for meta-analysis. Superior results were reported for oral NSAIDs when compared with placebo, concerning pain on weight bearing on short term, pain at rest on the short term, and less swelling on short- and intermediate term. For topical NSAIDs, superior results compared with placebo were found for pain at rest (short term), persistent pain (intermediate term), pain on weight bearing (short- and intermediate term) and for swelling (short and intermediate term). No trials were included comparing oral with topic NSAIDs, so conclusions regarding this comparison are not realistic. The current evidence is limited due to the low number of studies, lack of methodological quality of the included studies as well as the small sample size of the included studies. Nevertheless, the findings from this review support the use of NSAIDs for the initial treatment for acute ankle sprains. Meta-analysis of RCTs, Level I.

    Layered double hydroxides (LDHs) are ideal sorbents for solid phase extraction (SPE) because of the excellent ion exchange capacity and high specific surface area. However, difficult elution of the analytes from the LDHs is a problem due to the strong ionic interaction between anions and LDHs. High concentrated NaOH solution is employed to elute the sample, but it not suitable for analyzing by HPLC. To solve this problem, a simple acid-base neutralization method was proposed after elution, and then the neutral samples were directly injected to HPLC for analysis. Nickel-aluminum layered double hydroxides (NiAl-LDHs) were synthesized by co-precipitation method and packed into a micro pipette tip for the extraction of three non-steroidal anti-inflammatory drugs (NSAIDs) including ketoprofen, naproxen and flurbiprofen from aqueous samples. After optimization of the experimental parameters such as the concentration of the NaOH, sample pH, sampling rate and sample volume, excellent extraction efficiency towards three NSAIDs was obtained with high enrichment factors of 28-32. A NiAl-LDHs based SPE-HPLC method was developed for quantitative analysis of NSAIDs, and the method showed low limits of detection (0.002-0.1ng/mL), good linearity (R 2 ≥0.9995) and good reproducibility (intraday RSD≤4.37%). The developed method was also applied to the analysis of three NSAIDs in spiked human plasma and rat plasma after oral administration, which demonstrated the practicality of the proposed method.

    The pathogenesis of urticaria and angioedema induced by non-steroidal anti-inflammatory drugs (NSAIDs) is still obscure. We analyzed the clinical characteristics of patients with NSAIDs-induced urticaria and angioedema without asthma in Japan. We retrospectively collected the cases of NSAIDs-induced urticaria and angioedema from Japanese medical journals in 2000-2009. Seventy-six patients were analyzed. The male/female ratio was 1:2.5 and the mean age was 38.1 years. Urticaria was most frequent clinical manifestation in 3 groups; urticaria alone, urticaria and angioedema, and angioedema alone. Time interval from drug administration to onset was 5 minutes to 48 hours by aspirin at a dose of 25-1000 mg. Skin prick test was performed with aspirin in 33 patients, and the results were negative in all patients. Meloxicam, a selective cyclooxygenase-2 (COX-2) inhibitor, and celecoxib, a new selective COX-2 inhibitor, were administered safely in 4 of 6 patients and in 2 of 3 patients with NSAIDs-induced urticaria, respectively. These drugs were administered safely in all administered patients with NSAIDs-induced angioedema. Tiaramidehydrochroride (a basic COX-1 inhibitor) was safely used in 23 administered patients with NSAIDs-induced angioedema. Leukotriene receptor antagonists were effective in 2 of 5 patients administered, but aggravated symptoms in the others. Diversity of NSAIDs-induced urticaria and angioedema was shown in this study. Pathogenesis of NSAIDs-induced urticaria and angioedema without asthma seems to be different from that of NSAIDs-induced asthma.

    To clarify the mechanism of the protective effect of non-steroidal anti-inflammatory drugs (NSAIDs) on Alzheimer's disease, inactivation of cholinesterase (ChE) induced by NSAIDs was examined. Equine ChE and rat brain homogenate were incubated with NSAIDs and horseradish peroxidase (HRP) and H(2)O(2) (HRP-H(2)O(2)). ChE activity was measured by using 5,5'-dithiobis(nitrobenzoic acid). By using electron spin resonance, NSAID radicals induced by reaction with HRP-H(2)O(2) were detected in the presence of spin trap agents. Equine ChE was inactivated by mefenamic acid with HRP-H(2)O(2). ChE activity in rat brain homogenate decreased dependent on the concentration of mefenamic acid in the presence of HRP-H(2)O(2). NSAIDs diclofenac, indomethacin, phenylbutazone, piroxicam and salicylic acid inactivated ChE. Oxygen radical scavengers did not prevent inactivation of ChE induced by mefenamic acid with HRP-H(2)O(2). However, spin trap agents 5,5-dimethyl-1-pyrroline-l-oxide and N-methyl-nitrosopropane, reduced glutathione and ascorbic acid strongly inhibited inactivation of ChE, indicating participation of mefenamic acid radicals. Fluorescent emission of ChE peaked at 400 nm, and the Vmax value of ChE changed during interaction of mefenamic acid with HRP-H(2)O(2), indicating that ChE may be inactivated through modification of tyrosine residues by mefenamic radicals. The protective effect of NSAIDs on Alzheimer's disease seems to occur through inactivation of ChE induced by NSAIDs radicals.

    Low-dose acetylsalicylic acid (ASA; aspirin; 75-325 mg/day) is effective for the prevention of cardiovascular events, and its use in this indication is rapidly increasing. However, the use of ASA and, indeed, other non-steroidal anti-inflammatory drugs (NSAIDs) is limited by the incidence of adverse gastroduodenal events. OBJECTIVES AND SCOPE: To review the clinical evidence for, and the pharmacodynamic basis of, ASA-induced gastroduodenal toxicity in comparison with NSAIDs, and address the question of whether low-dose ASA is 'safe' from a gastroduodenal perspective. This was a narrative, descriptive review, rather than a formal systematic review. Adverse gastroduodenal effects, which are well known to occur with NSAIDs, are also prevalent in patients receiving low-dose ASA for cardiovascular protection even at doses as low as 75 mg/day. The risk of gastroduodenal toxicity is particularly high among 'at-risk' low-dose ASA patients (aged >70 years, previous ulcer or upper gastrointestinal bleeding and users of antiplatelets or NSAIDs). There are important differences in the mechanism of ASA-induced gastroduodenal toxicity, relative to NSAIDs. These differences include the effects on the cyclooxygenase (COX)-1 isoenzyme, local effects on the gastroduodenal mucosa specific to ASA and a reduction in platelet aggregation. Data suggest that ASA causes significant gastroduodenal damage even at the low doses used for cardiovascular protection. These effects (both systemic and possibly local) may be pharmacodynamically distinct from the gastroduodenal toxicity seen with NSAIDs. Studies are required to establish strategies for improving the tolerability of low-dose ASA, allowing patients to continue to benefit from the cardiovascular protection associated with such therapy.

    Non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with lower risk of certain cancers, but data on the effect on skin cancer risk have been limited and contradictory. We prospectively examined whether use of NSAIDS or acetaminophen was associated with a lower risk of skin cancer in women. The 92,125 Caucasian women in the Nurses' Health Study provided information on aspirin use in 1980. Other NSAIDs and acetaminophen were added in 1990. Medication use, frequency, and quantity were reassessed on biennial questionnaires. Through 2008, we confirmed 658 melanoma cases, 1,337 squamous cell carcinoma (SCC) cases, and had 15,079 self-reports of basal cell carcinoma (BCC). We used COX proportional hazards models to compute relative risks (RR) adjusted for known skin cancer risk factors. Neither aspirin nor non-aspirin NSAID use was associated with a lower risk of melanoma, SCC, or BCC, even for women with high quantity, frequency, or duration of use. Instead, we observed an increased risk of melanoma among current aspirin users (RR = 1.32, 95 % CI 1.03-1.70), though an increase of similar magnitude among past users and lack of a dose-response effect did not support a pharmacologic mechanism. We observed a mild reduction in SCC risk in current acetaminophen users (RR = 0.88, 95 % CI 0.75-1.02), with a linear decrease in risk with greater frequency of use (p = 0.04). Aspirin and other NSAIDs were not associated with a lower risk of melanoma, SCC, or BCC in women. Our large, prospective study does not support a chemoprotective effect of NSAIDs against skin cancers.

    Apoptosis is a highly regulated mechanism of cell death where pro-apoptotic proteins and caspases play an important role. Activation of pro-caspases at a definite time is essential to control the whole caspase cascade. Mitochondrion contains some pro-apoptotic proteins, which need to come out in cytoplasm for apoptotic function such as Cytochrome c (Cyt c), while the Bcl-2 protein family works as the guard of mitochondrial membrane and prevents the escape of Cyt c. Once Cyt c is out in cytoplasm, it binds with Apaf-1 (another pro-apoptotic protein also essential for proper cell differentiation) and pro-caspase-9, forming the Apoptosome complex. In this study, the role of two non-steroidal anti-inflammatory drugs (NSAIDs), Diclofenac and Celecoxib, in experimentally induced early neoplasm of colon via apoptosome mechanism had been studied. It has been recognized that the prolonged use of NSAIDs has its effect on reducing the risk of colorectal cancer through apoptotic pathways. However, the role of NSAIDs in respect of apoptosome is not clear. Western blotting and immunohistochemistry were performed, along with morphological and histological analysis. According to the expression levels of Cytochrome c, Apaf-1, Caspases, and Bcl-2, it was observed that NSAIDs do follow the mitochondrial or intrinsic pathway of apoptosis. The effects of Diclofenac and Celecoxib on the expression of pro- and anti-apoptotic proteins have been observed, which may constitute the mechanism by which the NSAIDs are efficient in controlling the proliferation of neoplasm in the colon.

    Full Text Available Aspirin (ASA and non-steroidal anti-inflammatory drugs (NSAIDs are a mainstay of therapy for the treatment of idiopathic pericarditis (IP. A comprehensive review consisting of pertinent clinical literature, pharmacokinetic, and pharmacodynamic considerations, has not been released in recent years. This review will facilitate the clinician’s understanding of pharmacotherapeutic considerations for using ASA/NSAIDs to treat IP. Data were compiled using clinical literature consisting of case reports, cohort data, retrospective and prospective studies, and manufacturer package inserts. ASA, ibuprofen, indometacin, and ketorolac relatively have the most evidence in the treatment of IP, provide symptomatic relief of IP, and should be tapered accordingly. ASA is the drug of choice in patients with coronary artery disease (CAD, heart failure (HF, or renal disease, but should be avoided in patients with asthma and nasal polyps, who are naïve to ASA therapy. Ibuprofen is an inexpensive and relatively accessible option in patients who do not have concomitant CAD, HF, or renal disease. Indometacin is not available over-the-counter in the USA, and has a relatively higher incidence of central nervous system (CNS adverse effects. Ketorolac is an intravenous option; however, clinicians must be mindful of the maximum dose that can be administered. While ASA/NSAIDs do not ameliorate the disease process of IP, they are part of first-line therapy (along with colchicine, for preventing recurrence of IP. ASA/NSAID choice should be dictated by comorbid conditions, tolerability, and adverse effects. Additionally, the clinician should be mindful of considerations such as tapering, high-sensitivity CRP monitoring, bleeding risk, and contraindications to ASA/NSAID therapy.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are the drugs most frequently involved in hypersensitivity drug reactions. Histamine is released in the allergic response to NSAIDs and is responsible for some of the clinical symptoms. The aim of this study is to analyze clinical association of functional polymorphisms in the genes coding for enzymes involved in histamine homeostasis with hypersensitivity response to NSAIDs. We studied a cohort of 442 unrelated Caucasian patients with hypersensitivity to NSAIDs. Patients who experienced three or more episodes with two or more different NSAIDs were included. If this requirement was not met diagnosis was established by challenge. A total of 414 healthy unrelated controls ethnically matched with patients and from the same geographic area were recruited. Analyses of the SNPs rs17740607, rs2073440, rs1801105, rs2052129, rs10156191, rs1049742 and rs1049793 in the HDC, HNMT and DAO genes were carried out by means of TaqMan assays. The detrimental DAO 16 Met allele (rs10156191), which causes decreased metabolic capacity, is overrepresented among patients with crossed-hypersensitivity to NSAIDs with an OR  = 1.7 (95% CI  = 1.3–2.1; Pc  = 0.0003) with a gene-dose effect (P = 0.0001). The association was replicated in two populations from different geographic areas (Pc  = 0.008 and Pc  = 0.004, respectively). Conclusions and implications The DAO polymorphism rs10156191 which causes impaired metabolism of circulating histamine is associated with the clinical response in crossed-hypersensitivity to NSAIDs and could be used as a biomarker of response.

    An accurate, simple, sensitive and selective micellar liquid chromatographic method has been developed for the simultaneous determination of caffeine (CAF) and two non-steroidal anti-inflammatory drugs, namely ibuprofen (IBU) and ketoprofen (KET). The chemometric approach was applied to the optimization of separation of the studied drugs. To optimize their separation, the effect of six experimental parameters on retention was investigated by means of multivariate analysis. Separation was conducted using an ODS C18 (150 × 4.6 mm i.d.) stainless steel column at ambient temperature with UV detection at 260 nm. A mobile phase composed of 40 mM sodium dodecyl sulphate (SDS), 10% 1-propanol and 0.3% tri-ethylamine in 0.02 M phosphoric acid adjusted to pH 3 has been used at a flow rate of 1 mL/min. Regression models were characterized by both descriptive and predictive ability (R(2) ≥ 97.9% and R(cv)(2) ≥ 96.2%) and allowed the chromatographic separation of the drugs with a good resolution and a total analysis time within 15 min. The calibration curves were rectilinear over the concentration ranges of 2.0-25.0, 1.5-15.0 and 1.0-10.0 µg/mL for IBU, KET and CAF, respectively, with detection limits of 1.2, 1.0 and 0.6 µg/mL, and quantification limits of 1.6, 1.2 and 0.8 µg/mL, respectively. The results obtained were in good agreement with those obtained by the comparison method. © The Author [2013]. Published by Oxford University Press. All rights reserved.

    The aim of this study was to quantify and describe the prescription profile, as well as to assess the adequacy of treatment with non-steroidal anti-inflammatory drugs (NSAIDs) in the diabetic population of a health district. This is a descriptive, cross-sectional study aimed at a target population of 2,795 diabetic patients. Data were collected from the computerised clinical records of a sample of 380 individuals. The adequacy of treatment was assessed using the recommendations proposed by the Spanish societies of Rheumatology, Cardiology and Gastroenterology. More than one-quarter (28%) of the diabetic patients received treatment with NSAIDs. The most commonly used ones were ibuprofen, naproxen, and dexketoprofen, with a defined daily dose per 1,000 inhabitants per day of 35.3, 17.2, and 13.2, respectively. In patients with a history of chronic kidney disease and cardiovascular high risk, fewer NSAIDs were prescribed, while they were used most frequently in patients with a risk for gastrointestinal adverse events. The prescription was considered adequate in 46.5% of diabetic patients. The main causes of inappropriate use were the inadequate prescription of NSAIDs (25.2%), and the use of any NSAID other than naproxen (20.6%). The most prescribed NSAIDs were those showing a low cardiovascular risk profile. Treatment with NSAIDs was inadequate in more than half of the patients. Risk factors for cardiovascular, and especially gastrointestinal, events must be considered in order to avoid its use when not indicated, as well as the use of any NSAIDs other than naproxen.

    Effect of tolmetin sodium(Tol) on acute and subacute exudative inflammation was tested in experimental animals. Tol had a potent inhibitory activity (ED50 = 0.75 mg/kg, p.o.) on the increased vascular permeability induced by acetic acid in mice, and the potency was about 0.4 times that of indomethacin (Ind), and 6-93 times that of ibuprofen (Ibu), phenylbutazone(Phe) and aspirin(Asp). The inhibitory activity of Tol(ED50 = 18.2 mg/kg, p.o.) on UV-induced erythema in guinea pigs was about 0.3 times that of Ind. A recovery of the hind paw edema of rats, produced by a mixture of kaolin and carrageenin, was promoted by oral administration of Tol(2.5 approximately 20 mg/kg x 5/2 days). Tol(80 mg/kg/day, p.o.) showed a significant activity in inhibiting the exudation caused by croton oil in rats, and the activity was about 0.025 times that of Ind and greater than that of Ibu, Phe and Asp. Tol(100-800 microgram/ml) inhibited in a dose-dependent manner the phytohemagglutinin-induced blast transformation of cultured lymphocytes from rat thymus, as did salicylic acid. In vitro, Tol showed a potent activity similar to that of Ibu and Phe in preventing the denaturation of bovine serum albumin and the lysis of rat erythrocytes. From these results, it is suggested that Tol has a particularly potent inhibitory activity on acute exudative inflammation, and the mode of action may be attributed to a mechanism similar to that seen with other acidic non-steroidal anti-inflammatory drugs.

    Pain is a common feature of childhood and adolescence around the world, and for many young people, that pain is chronic. The World Health Organization guidelines for pharmacological treatments for children's persisting pain acknowledge that pain in children is a major public health concern of high significance in most parts of the world. While in the past pain was largely dismissed and was frequently left untreated, views on children's pain have changed over time, and relief of pain is now seen as important.We designed a suite of seven reviews on chronic non-cancer pain and cancer pain (looking at antidepressants, antiepileptic drugs, non-steroidal anti-inflammatory drugs, opioids, and paracetamol) in order to review the evidence for children's pain utilising pharmacological interventions.As the leading cause of morbidity in the world today, chronic disease (and its associated pain) is a major health concern. Chronic pain (that is pain lasting three months or longer) can arise in the paediatric population in a variety of pathophysiological classifications (nociceptive, neuropathic, or idiopathic) from genetic conditions, nerve damage pain, chronic musculoskeletal pain, and chronic abdominal pain, as well as for other unknown reasons.Non-steroidal anti-inflammatory drugs (NSAIDs) are used to treat pain, reduce fever, and for their anti-inflammation properties. They are commonly used within paediatric pain management. Non-steroidal anti-inflammatory drugs are currently licensed for use in Western countries, however they are not approved for infants under three months old. The main adverse effects include renal impairment and gastrointestinal issues. Common side effects in children include diarrhoea, headache, nausea, constipation, rash, dizziness, and abdominal pain. To assess the analgesic efficacy and adverse events of NSAIDs used to treat chronic non-cancer pain in children and adolescents aged between birth and 17 years, in any setting.

    While it is now clear that paracetamol is ineffective for spinal pain, there is not consensus on the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) for this condition. We performed a systematic review with meta-analysis to determine the efficacy and safety of NSAIDs for spinal pain. We searched MEDLINE, EMBASE, CINAHL, CENTRAL and LILACS for randomised controlled trials comparing the efficacy and safety of NSAIDs with placebo for spinal pain. Reviewers extracted data, assessed risk of bias and evaluated the quality of evidence using the Grade of Recommendations Assessment, Development and Evaluation approach. A between-group difference of 10 points (on a 0-100 scale) was used for pain and disability as the smallest worthwhile effect, as well as to calculate numbers needed to treat. Random-effects models were used to calculate mean differences or risk ratios with 95% CIs. We included 35 randomised placebo-controlled trials. NSAIDs reduced pain and disability, but provided clinically unimportant effects over placebo. Six participants (95% CI 4 to 10) needed to be treated with NSAIDs, rather than placebo, for one additional participant to achieve clinically important pain reduction. When looking at different types of spinal pain, outcomes or time points, in only 3 of the 14 analyses were the pooled treatment effects marginally above our threshold for clinical importance. NSAIDs increased the risk of gastrointestinal reactions by 2.5 times (95% CI 1.2 to 5.2), although the median duration of included trials was 7 days. NSAIDs are effective for spinal pain, but the magnitude of the difference in outcomes between the intervention and placebo groups is not clinically important. At present, there are no simple analgesics that provide clinically important effects for spinal pain over placebo. There is an urgent need to develop new drug therapies for this condition.

    To assess the cost-effectiveness of celecoxib and non-selective non-steroidal anti-inflammatory drugs for the treatment of osteoarthritis in clinical practice in Spain. A decision-tree model using distribution, doses, treatment duration and incidence of GI and CV events observed in the pragmatic PROBE-designed «GI-Reasons» trial was used for cost-effectiveness. Effectiveness was expressed in terms of event averted and quality-adjusted life-years (QALY) gained. QALY were calculated based on utility decrement in case of any adverse events reported in GI-Reasons trial. The National Health System perspective in Spain was applied; cost calculations included current prices of drugs plus cost of adverse events occurred. The analysis was expressed as an incremental cost-effectiveness ratio per QALY gained and per event averted. One-way and probabilistic analyses were performed. Compared with non-selective non-steroidal anti-inflammatory drugs, at current prices, celecoxib treatment had higher overall treatment costs €201 and €157, respectively. However, celecoxib was associated with a slight increase in QALY gain and significantly lower incidence of gastrointestinal events (p<.001), with mean incremental cost-effectiveness ratio of €13,286 per QALY gained and €4,471 per event averted. Sensitivity analyses were robust, and confirmed the results of the base case. Celecoxib at current price may be considered as a cost-effective alternative vs. non-selective non-steroidal anti-inflammatory drugs in the treatment of osteoarthritis in daily practice in the Spanish NHS.

    Full Text Available While the number of clinical experiments investigating the effects of non-steroid anti-inflammatory drugs (NSAIDs on the cardiovascular (CV events has significantly increased over the last two decades, basic research related to the mechanism by which NSAIDs cause CV dysfunction is limited. High variability in the clinical trials conducted (different populations, dosages, exposure and types of NSAIDs has led to results which are difficult to interpret and compare between studies. Are there some NSAIDs safer than other from the standpoint of CV risk? We have try to answer at some aspects of this question.

    Full Text Available BACKGROUND: Randomised trials have highlighted the cardiovascular risks of non-steroidal anti-inflammatory drugs (NSAIDs in high doses and sometimes atypical settings. Here, we provide estimates of the comparative risks with individual NSAIDs at typical doses in community settings. METHODS AND FINDINGS: We performed a systematic review of community-based controlled observational studies. We conducted comprehensive literature searches, extracted adjusted relative risk (RR estimates, and pooled the estimates for major cardiovascular events associated with use of individual NSAIDs, in different doses, and in populations with low and high background risks of cardiovascular events. We also compared individual drugs in pair-wise (within study analyses, generating ratios of RRs (RRRs. Thirty case-control studies included 184,946 cardiovascular events, and 21 cohort studies described outcomes in >2.7 million exposed individuals. Of the extensively studied drugs (ten or more studies, the highest overall risks were seen with rofecoxib, 1.45 (95% CI 1.33, 1.59, and diclofenac, 1.40 (1.27, 1.55, and the lowest with ibuprofen, 1.18 (1.11, 1.25, and naproxen, 1.09 (1.02, 1.16. In a sub-set of studies, risk was elevated with low doses of rofecoxib, 1.37 (1.20, 1.57, celecoxib, 1.26 (1.09, 1.47, and diclofenac, 1.22 (1.12, 1.33, and rose in each case with higher doses. Ibuprofen risk was seen only with higher doses. Naproxen was risk-neutral at all doses. Of the less studied drugs etoricoxib, 2.05 (1.45, 2.88, etodolac, 1.55 (1.28, 1.87, and indomethacin, 1.30 (1.19, 1.41, had the highest risks. In pair-wise comparisons, etoricoxib had a higher RR than ibuprofen, RRR = 1.68 (99% CI 1.14, 2.49, and naproxen, RRR = 1.75 (1.16, 2.64; etodolac was not significantly different from naproxen and ibuprofen. Naproxen had a significantly lower risk than ibuprofen, RRR = 0.92 (0.87, 0.99. RR estimates were constant with different background risks for

    Full Text Available A simple and selective micellar electrokinetic chromatographic (MEKC method has been developed for the analysis of five pharmaceutical binary mixtures containing three non-steroidal anti-inflammatory drugs (NSAIDs. The investigated mixtures were Ibuprofen (IP–Paracetamol (PC, Ibuprofen (IP–Chlorzoxazone (CZ, Ibuprofen (IP–Methocarbamol (MC, Ketoprofen (KP–Chlorzoxazone (CZ and Diclofenac sodium (DS–Lidocaine hydrochloride (LC. The separation was run for all mixtures using borate buffer (20 mM, pH 9 containing 15% (v/v methanol and 100 mM sodium dodecyl sulphate (SDS at 15 kV and the components were detected at 214 nm. Different factors affecting the electrophoretic mobility of the seven investigated drugs were studied and optimized. The method was validated according to international conference of harmonization (ICH guidelines and United States pharmacopoeia (USP. The method was applied to the analysis of five pharmaceutical binary mixtures in their dosage forms. The results were compared with other reported high performance liquid chromatographic methods and no significant differences were observed.

    This is an updated version of the original Cochrane review published in 2014, Issue 4. Cervical intraepithelial neoplasia (CIN) precedes the development of invasive carcinoma of the cervix. Current treatment of CIN is quite effective, but there is morbidity for the patient related to pain, bleeding, infection, cervical stenosis and premature birth in a subsequent pregnancy. Effective treatment with medications, rather than surgery, would be beneficial. To evaluate the effectiveness and safety of non-steroidal anti-inflammatory agents (NSAIDs), including cyclooxygenase-2 (COX-2) inhibitors, to induce regression and prevent the progression of CIN. Previously, we searched the Cochrane Gynaecological Cancer Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (2013, Issue 11), MEDLINE (November, 2013) and Embase (November week 48, 2013). An updated search was performed in August 2017 for CENTRAL (2017, Issue 8), MEDLINE (July, week 3, 2017) and Embase (July week 31, 2017). Trial registries and journals were also searched as part of the update. Randomised controlled trials (RCTs) or controlled trials of NSAIDs in the treatment of CIN. Three review authors independently abstracted data and assessed risks of bias in accordance with Cochrane methodology. Outcome data were pooled using fixed-effect meta-analyses. In three RCTs, 171 women over the age of 18 years were randomised to receive celecoxib 400 mg daily for 14 to 18 weeks versus placebo (one study, 130 participants), celecoxib 200 mg twice daily by mouth for six months versus placebo (one study, 25 participants), or rofecoxib 25 mg once daily by mouth for three months versus placebo (one study, 16 participants). The study with rofecoxib was discontinued when the medicine was withdrawn from the market in 2004. The trials ran from June 2005 to April 2012, June 2002 to October 2003, and May to October 2004, respectively. We have chosen to include the data from the rofecoxib study as

    The use of non-steroidal anti-inflammatory drugs (NSAIDs) in the treatment of rheumatoid arthritis (RA) is limited by their toxicity. We evaluated the anti-inflammatory efficacy and safety of three novel modified NSAIDs, phospho-aspirin, phospho-ibuprofen and phospho-sulindac. We determined the anti-inflammatory effects and gastrointestinal safety of the phospho-NSAIDs in the rat adjuvant arthritis model and studied their mechanism of action in cultured cells, Cytokines were measured with elisa and activation of nuclear factor-κB (NF-κB) by immunohistochemistry. All three phospho-NSAIDs showed less gastrointestinal toxicity than their parent compounds and demonstrated strong anti-inflammatory effects, essentially reversing joint inflammation and oedema. They have a broad but not uniform effect on the expression of relevant cytokines, in general decreasing IL-6 and IL-1β and increasing IL-10 levels in rat plasma and cultured cells. Phospho-sulindac and phospho-ibuprofen but not phospho-aspirin suppressed PGE(2) production in vitro, whereas phospho-aspirin (in contrast to aspirin) showed the same effect in vivo. In joint tissues, phospho-aspirin inhibited NF-κB activation, and suppressed inflammation and bone resorption. Phospho-aspirin also inhibited Jurkat T cell proliferation. In general, phospho-aspirin had greater efficacy but different effects upon inflammatory mediators compared with aspirin. The chemical modification of the parent NSAIDs seems crucial for their safety and efficacy. Phospho-aspirin, phospho-ibuprofen and phospho-sulindac were safer than their parent NSAIDs, were highly effective in rat adjuvant arthritis and inhibited many key mediators in the pathophysiology of RA. These novel compounds are promising candidate drugs for the treatment of RA and merit further evaluation. © 2011 The Authors.

    Axial spondyloarthritis (axSpA) comprises ankylosing spondylitis (radiographic axSpA) and non-radiographic (nr-)axSpA and is associated with psoriasis, uveitis and inflammatory bowel disease. Non-steroidal anti-inflammatory drugs (NSAIDs) are recommended as first-line drug treatment. To determine the benefits and harms of NSAIDs in axSpA. We searched CENTRAL, MEDLINE and EMBASE to 18 June 2014. Randomised controlled trials (RCTs) or quasi-RCTs of NSAIDs versus placebo or any comparator in adults with axSpA and observational cohort studies studying the long term effect (≥ six months) of NSAIDs on radiographic progression or adverse events (AEs). The main comparions were traditional or COX-2 NSAIDs versus placebo. The major outcomes were pain, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Metrology Index (BASMI), radiographic progression, number of withdrawals due to AEs and number of serious AEs Two review authors independently selected trials for inclusion, assessed the risk of bias, extracted data and assessed the quality of evidence for major outcomes using GRADE. We included 39 studies (35 RCTs, two quasi-RCTs and two cohort studies); and 29 RCTs and two quasi-RCTs (n = 4356) in quantitative analyses for the comparisons: traditional NSAIDs versus placebo, cyclo-oxygenase-2 (COX-2) versus placebo, COX-2 versus traditional NSAIDs, NSAIDs versus NSAIDs, naproxen versus other NSAIDs, low versus high dose. Most trials were at unclear risk of selection bias (n = 29), although blinding of participants and personnel was adequate in 24 trials. Twenty-five trials had low risk of attrition bias and 29 trials had low risk of reporting bias. Risk of bias in both cohort studies was high for study participation, and low or unclear for all other criteria. No trials in the meta-analyses assessed patients with nr-axSpA.Traditional NSAIDs were more beneficial than placebo at six

    A 19-year-old woman developed high fever, headache, and nausea after taking Loxoprofen for pharyngitis, followed by disturbed consciousness and nuchal stiffness. The patient and her mother had a history of Raynaud's phenomenon. Cerebrospinal fluid (CSF) examination indicated a diagnosis of aseptic meningitis and revealed high levels of Q albumin and IgG index. Anti-RNP antibodies were positive in serum and CSF. Her symptoms disappeared immediately after cessation of Loxoprofen and a drug lymphocyte stimulation test was negative, confirming a diagnosis of non-steroidal anti-inflammatory drugs (NSAIDs)-induced aseptic meningitis. It should be kept in mind that an immune abnormality such as serum and CSF anti-RNP antibodies may play a role in development of NSAIDs-induced aseptic meningitis. A history of usage of NSAIDs and a thorough examination of collagen diseases are useful for identification of the origin of aseptic meningitis in a young woman.

    Full Text Available In the present work, we investigated the effect of non-steroidal anti-inflammatory drugs (NSAIDs on the monophenolase and diphenolase activity of mushroom tyrosinase. The results showed that diflunisal and indomethacin inhibited both monophenolase and diphenolase activity. For monophenolase activity, the lag time was extended in the presence of diflunisal. In the presence of indomethacin, the lag time did not change. IC50 values of monophenolase activity were estimated to be 0.112 mM (diflunisal and 1.78 mM (indomethacin. Kinetic studies of monophenolase activity revealed that both diflunisal and indomethacin were non-competitive inhibitors. For diphenolase activity, IC50 values were estimated to be 0.197 mM (diflunisal and 0.509 mM (indomethacin. Diflunisal and indomethacin were also found to be non-competitive diphenolase inhibitors.

    We investigated the effect of non-steroidal anti-inflammatory drugs on prostaglandins (PGs) and 12-hydroxyeicosatetraenoic acid (12-HETE) formation by inflamed human gingival tissues. Gingival tissue homogenates were incubated with 14 C-arachidonic acid in the presence of indomethacin, piroxicam, or ibuprofen, and the organic solvent extracts were chromatographed on silica gel plates with standards for radiometric assay. There was a significant negative trend between the doses (10(-7)-10(-3) M) of each of indomethacin, piroxicam, and ibuprofen, and the amounts of PGF2 alpha, PGE2, PGD2, and 15-keto-PGE2 produced. All three drugs have a significant inhibitory effect on PGs and 12-HETE production at 10(-3) M when compared with the control. The rank order effectiveness of the drugs, at 10(-3) M, on PG inhibition was indomethacin greater than piroxicam greater than ibuprofen, and on 12-HETE inhibition was indomethacin greater than ibuprofen greater than piroxicam

    The efficacy and tolerability of nimesulide, a non-steroidal anti-inflammatory drug (NSAID) 100 mg twice daily were compared with diclofenac 75 mg b.i.d. in short term treatment of acute shoulder (acute subdeltoid bursitis and bicipital tendinitis) in adult patients. In this double-blind (double-dummy), randomised, parallel group study over two weeks, 122 patients were included. The Mann-Whitney statistics revealed therapeutic equivalence of both treatments with a slight superiority for nimesulide. The tolerability of nimesulide, judged by investigators and patients and analysed statistically, was superior to that of diclofenac. Thus, the benefit-risk relationship was better for the test drug than for the reference drug.

    Brain damage after insult and cognitive decline are related to excitotoxicity and strongly influenced by aging, yet mechanisms of aging-dependent susceptibility to excitotoxicity are poorly known. Several non-steroidal anti-inflammatory drugs (NSAIDs) may prevent excitotoxicity and cognitive decline in the elderly by an unknown mechanism. Interestingly, after several weeks in vitro, hippocampal neurons display important hallmarks of neuronal aging in vivo. Accordingly, rat hippocampal neurons cultured for several weeks were used to investigate mechanisms of aging-related susceptibility to excitotoxicity and neuroprotection by NSAIDs. We found that NMDA increased cytosolic Ca(2+) concentration in young, mature and aged neurons but only promoted apoptosis in aged neurons. Resting Ca(2+) levels and responses to NMDA increased with time in culture which correlated with changes in expression of NMDA receptor subunits. In addition, NMDA promoted mitochondrial Ca(2+) uptake only in aged cultures. Consistently, specific inhibition of mitochondrial Ca(2+) uptake decreased apoptosis. Finally, we found that a series of NSAIDs depolarized mitochondria and inhibited mitochondrial Ca(2+) overload, thus preventing NMDA-induced apoptosis in aged cultures. We conclude that mitochondrial Ca(2+) uptake is critical for age-related susceptibility to excitotoxicity and neuroprotection by NSAIDs. Rat hippocampal neurons aged in culture were used to investigate mechanisms of age-related susceptibility to excitotoxicity and neuroprotection by non-steroidal anti-inflammatory drugs (NSAIDs). Old neurons display enhanced resting calcium and responses to NMDA along with increased expression of NMDA receptor subunits NR1 and NR2A altogether favoring mitochondrial calcium overload. NSAIDs protect neurons against excitotoxicity acting on mitochondrial calcium uptake. NMDA, N methyl d-aspartate. © 2014 International Society for Neurochemistry.

    Growing evidence from epidemiologic and preclinical studies suggests that nonsteroidal anti-inflammatory drugs (NSAIDs) reduce the risk of gastrointestinal (GI) cancers, including esophageal, gastric, pancreatic, colorectal cancer, and hepatocellular carcinoma. However, there is also evidence indicating the absence of this benefit. The exact mechanism of NSAIDs' action on GI tumors is not known. Although some studies have suggested inhibition of carcinogenesis by NSAIDs through suppression effect on inflammation-associated cyclooxygenase-2 (COX-2) expression, other studies have suggested COX-2-independent mechanisms. Herein, we summarize the current state of-the-science regarding NSAID benefit for patients with GI cancers. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Non-steroidal anti-inflammatory drugs (NSAIDs) have been implemented in clinical settings for a long time for their anti-inflammatory effects. With the number of NSAID users increasing, gastroenterological physicians and researchers have worked hard to prevent and treat NSAID-induced gastric mucosal injury, an effort that has for the large part being successful. However, the struggle against NSAID-induced mucosal damage has taken on a new urgency due to the discovery of NSAID-induced small intestinal mucosal injury. Although the main mechanism by which NSAIDs induce small intestinal mucosal injury has been thought to depend on the inhibitory effect of NSAIDs on cyclooxygenase (COX) activity, recent studies have revealed the importance of mitochondria-derived reactive oxygen species (ROS) production, which occurs independently of COX-inhibition. ROS production is an especially important factor in the increase of small intestinal epithelial cell permeability, an early stage in the process of small intestinal mucosal injury. By clarifying the precise mechanism, together with its clinical features using novel endoscopy, effective strategies for preventing NSAID-induced small intestinal damage, especially targeting mitochondria-derived ROS production, may be developed.

  19. [Recommendation for the prevention and treatment of non-steroidal anti-inflammatory drug-induced gastrointestinal ulcers and its complications].

    2017-01-01

    Non-steroidal anti-inflammatory drugs (NSAIDs) are a broad class of non glucocorticoid drugs which are extensively used in anti-inflammatory, analgesic, and antipyretic therapies. However, NSAIDs may cause many side effects, most commonly in gastrointestinal(GI) tract. Cardiovascular system, kidney, liver, central nervous system and hematopoietic system are also involved. NSAID-induced GI side effects not only endanger the patients' health, increase mortality, but also greatly increase the cost of medical care. Therefore, how to reduce GI side effects is of particular concern to clinicians. The Chinese Rheumatism Data Center(CRDC) and Chinese Systemic Lupus Erythematosus Treatment and Research Group(CSTAR) compose a "Recommendation for the prevention and treatment of non-steroidal anti-inflammatory drug-induced gastrointestinal ulcers and its complications" , as following: (1) GI lesions are the most common side effects of NSAIDs. (2) NSAID-induced GI side effects include gastritis, esophagitis, gastric and duodenal ulcers, bleeding, perforation and obstruction. (3) With the application of capsule endoscopy and small intestinal endoscopy, growing attention is being paid to the NASID-induced small intestine mucosa damage, which is mainly erosion and ulcer. (4) Risk factors related to NSAID-induced GI ulcers include: Helicobacter pylori (Hp) infection, age> 65 years, past history of GI ulcers, high doses of NSAIDs, multiple-drug combination therapy, and comorbidities, such as cardiovascular disease and nephropathy.(5) GI and cardiovascular function should be evaluated before using NSAIDs and gastric mucosal protective agents. (6) The risk of GI ulcers and complications caused by selective cyclooxygenase-2 (COX-2) inhibitors is less than that of non-selective COX-2 inhibitors. (7)Hp eradication therapy helps to cure GI ulcers and prevent recurrence when Hp infection is positive in NSAID-induced ulcers. (8) Proton pump inhibitor (PPI) is the first choice for the

    The nonsteroidal anti-inflammatory drug diclofenac is extremely toxic to Old World Gyps vultures (median lethal dose -0.1-0.2 mg/kg), evoking visceral gout, renal necrosis, and mortality within a few days of exposure. Unintentional secondary poisoning of vultures that fed upon carcasses of diclofenac-treated livestock decimated populations in the Indian subcontinent. Because of the widespread use of diclofenac and other cyclooxygenase-2 inhibiting drugs, a toxicological study was undertaken in turkey vultures (Cathartes aura) as an initial step in examining sensitivity of New World scavenging birds. Two trials were conducted entailing oral gavage of diclofenac at doses ranging from 0.08 to 25 mg/kg body weight. Birds were observed for 7 d, blood samples were collected for plasma chemistry (predose and 12, 24, and 48 h and 7 d postdose), and select individuals were necropsied. Diclofenac failed to evoke overt signs of toxicity, visceral gout, renal necrosis, or elevate plasma uric acid at concentrations greater than 100 times the estimated median lethal dose reported for Gyps vultures. For turkey vultures receiving 8 or 25 mg/kg, the plasma half-life of diclofenac was estimated to be 6 h, and it was apparently cleared after several days as no residues were detectable in liver or kidney at necropsy. Differential sensitivity among avian species is a hallmark of cyclooxygenase-2 inhibitors, and despite the tolerance of turkey vultures to diclofenac, additional studies in related scavenging species seem warranted.

    In this study conventional electrospinning (ESp) was used to prepare a series of buccal films containing indomethacin (INDO, a nonsteroidal anti-inflammatory drug), Ethocel (10), hydroxypropylmethylcellulose (HPMC) and Tween ® 80 at various concentrations. The films were characterized using scanning electron microscopy (SEM) and atomic force microscopy (AFM), fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, differential scanning calorimetry (DSC) and X-ray diffraction (XRD). Drug release behaviour was assessed in vitro (buffer pH6.8). SEM revealed film morphology and mean fibre diameter was dependent on the process formulation. INDO was encapsulated in the amorphous state once electrospun as evidenced from DSC and XRD studies. The presence of other excipients within fibrous matrices was confirmed using FTIR and Raman spectroscopy. Loading and release of INDO from filamentous structures was influenced by formulation composition; indicating potential to 'fine-tune' dosage forms. Given that ESp is a one-step preparation method and operational at ambient conditions; an attractive route for engineering tailored film type dosage forms is presented. This is a valuable approach for optimizing dosage forms as needed in a single step for various age groups. Copyright © 2017 Elsevier B.V. All rights reserved.

    We examined the effects of non-steroidal anti-inflammatory drugs on cognitive decline as a function of phase of pre-clinical Alzheimer disease. Given recent findings that cognitive decline accelerates as clinical diagnosis is approached, we used rate of decline as a proxy for phase of pre-clinical Alzheimer disease. We fit growth mixture models of Modified Mini-Mental State (3MS) Examination trajectories with data from 2388 participants in the Alzheimer's Disease Anti-inflammatory Prevention Trial and included class-specific effects of naproxen and celecoxib. We identified three classes: "no decline", "slow decline", and "fast decline", and examined the effects of celecoxib and naproxen on linear slope and rate of change by class. Inclusion of quadratic terms improved fit of the model (-2 log likelihood difference: 369.23; p < 0.001) but resulted in reversal of effects over time. Over 4 years, participants in the slow-decline class on placebo typically lost 6.6 3MS points, whereas those on naproxen lost 3.1 points (p-value for difference: 0.19). Participants in the fast-decline class on placebo typically lost 11.2 points, but those on celecoxib first declined and then gained points (p-value for difference from placebo: 0.04), whereas those on naproxen showed a typical decline of 24.9 points (p-value for difference from placebo: <0.0001). Our results appeared statistically robust but provided some unexpected contrasts in effects of different treatments at different times. Naproxen may attenuate cognitive decline in slow decliners while accelerating decline in fast decliners. Celecoxib appeared to have similar effects at first but then attenuated change in fast decliners. Copyright © 2011 John Wiley & Sons, Ltd.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) may disrupt control of blood pressure in hypertensive patients and increase their risk of morbidity, mortality, and the costs of care. The objective of this study was to examine the association between incident use of NSAIDs and blood pressure in patients with hypertension. We conducted a retrospective cohort study of adult hypertensive patients to determine the effects of their first prescription for NSAID on systolic blood pressure and antihypertensive drug intensification. Data were collected from an electronic medical record serving an academic general medicine practice in Indianapolis, Indiana, USA. Using propensity scores to minimize bias, we matched a cohort of 1,340 users of NSAIDs with 1,340 users of acetaminophen. Propensity score models included covariates likely to affect blood pressure or the use of NSAIDs. The study outcomes were the mean systolic blood pressure measurement after starting NSAIDs and changes in antihypertensive therapy. Compared to patients using acetaminophen, NSAID users had a 2 mmHg increase in systolic blood pressure (95% CI, 0.7 to 3.3). Ibuprofen was associated with a 3 mmHg increase in systolic blood pressure compared to naproxen (95% CI, 0.5 to 4.6), and a 5 mmHg increase compared to celecoxib (95% CI, 0.4 to 10). The systolic blood pressure increase was 3 mmHg in a subgroup of patients concomitantly prescribed angiotensin converting enzyme inhibitors or calcium channel blockers and 6 mmHg among those prescribed a beta-adrenergic blocker. Blood pressure changes in patients prescribed diuretics or multiple antihypertensives were not statistically significant. Compared to acetaminophen, incident use of NSAIDs, particularly ibuprofen, is associated with a small increase in systolic blood pressure in hypertensive patients. Effects in patients prescribed diuretics or multiple antihypertensives are negligible.

    Full Text Available Abstract Background Non-steroidal anti-inflammatory (NSAID medications are a common cause of reported adverse drug side-effects. This study describes the prevalence of non-steroidal anti-inflammatory (NSAID use (other than low-dose aspirin and the presence of co-existing relative contraindications to NSAID use and chronic conditions in a representative population sample. Methods Data were analysed from 3,206 adults attending first follow-up of the North West Adelaide Health Study (NWAHS in 2004 - 2006, a longitudinal representative population study. Medications were brought into study clinic visits by participants. Clinical assessment included measured blood pressure, kidney function, serum cholesterol, blood glucose. Questionnaires assessed demographics, lifestyle risk factors, physician-diagnosed chronic conditions. Data were weighted to census measures by region, age group, gender, and probability of selection in the household, to provide population representative estimates. Pearson's Chi-square tests determined significant differences in proportions. Multiple logistic regression was used to examine associations of socio-demographic characteristics with use of NSAIDs. Results Of 3,175 participants, 357 (11.2%, and 16% of those aged > 55 years, reported using either non-specific NSAIDs or COX-2 inhibitors, other than low-dose aspirin. Among people using NSAIDs, 60.8% had hypertension, 30.8% had Stage 3 or higher chronic kidney disease, 17.2% had a history of cardiovascular disease (CVD and 20.7% had a > 15% 10-year CVD risk. The prevalence of NSAID use among people with hypertension was 16%, with kidney disease 15.9%, and a history of CVD 20.0%. Among people taking diuretics, 24.1% were also taking NSAIDs, and of those taking medications for gastro-esophageal reflux, 24.7% were on NSAIDs. Prescription-only COX-2 inhibitors, but not other NSAIDs, were used more by people > 75 years than by 35-54 year olds (OR 3.7, 95% CI 2.0, 6.7, and also were

    Mycobacterium tuberculosis (TB) is one of the world's most devastating public health threats. Our goal is to evaluate whether the use of non-steroidal anti-inflammatory drugs (NSAIDs) affect the risk of new incident active TB disease. We conducted a nested case-control analysis by using a 1 million longitudinally followed cohort, from Taiwan's national health insurance research database. Effects of NSAIDs on active TB were estimated by conditional logistic regression and adjusted using a TB-specific disease risk score (DRS). NSAIDs exposures were defined as having a prescription record of NSAIDs ≧ 7 days that ended between 31 and 90 days prior to the index date. A total of 123,419 users of traditional NSAIDs, 16,392 users of cyclooxygenase-2 selective inhibitor (Coxibs), and 4706 incident cases of active TB were identified. Compared with nonusers, use of traditional NSAIDs was associated with an increased risk of TB in the unadjusted analysis ([RR], 1.39; 95% [CI], 1.24 - 1.57 and DRS adjusted analysis ([ARR], 1.30; 95% [CI], 1.15- 1.47). However, use of Coxibs was not associated with a significant increase in the risk of TB after DRS adjustment ([ARR], 1.23; 95% [CI], 0.89 - 1.70). In this large population-based study, we found that subjects using traditional NSAIDs were associated with increased risk for active TB. We did not find evidence for a causative mechanism between traditional NSAIDs and TB, and more research is required to verify whether the association between traditional NSAIDs and TB is causal, or simply reflects an increased use of anti-inflammatory drugs in the early phases of TB onset.

    BACKGROUND AND PURPOSE Non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to induce PG-independent anti-inflammatory actions. Here, we investigated the role of three different NSAIDs (naproxen, ibuprofen and oxaprozin) on neutrophil responses to CXCL8 and C5a. EXPERIMENTAL APPROACH Human neutrophils were isolated from healthy volunteers by dextran and Ficoll-Hypaque density gradients. Neutrophils were pre-incubated with different concentrations (1–100 µM) of NSAIDs or kinase inhibitors. Neutrophil degranulation into supernatants was tested by elisa and zymography. Neutrophil chemotaxis was determined using Boyden chambers. F-actin polymerization was determined by Alexa-Fluor 488-conjugated phalloidin fluorescent assay. Integrin expression was assessed by flow cytometry. The phosphorylation of intracellular kinases was studied by Western blot. KEY RESULTS Pretreatment with NSAIDs did not affect neutrophil degranulation, but inhibited neutrophil migration and polymerization of F-actin, in response to CXCL8 and C5a. Pretreatment with different NSAIDs prevented C5a-induced integrin (CD11b) up-regulation, while only ibuprofen reduced CXCL8-induced CD11b up-regulation. Pre-incubation with naproxen or oxaprozin, but not ibuprofen, inhibited the PI3K/Akt-dependent chemotactic pathways. Both endogenous (released in cell supernatants) or exogenous (added to cell cultures) PGE2 did not affect C5a- or CXCL8-induced activities. Short-term incubation with NSAIDs did not affect neutrophil PGE2 release. CONCLUSION AND IMPLICATIONS Treatment with NSAIDs reduced C5a- and CXCL8-induced neutrophil migration and F-actin polymerization via different mechanisms. Inhibition by ibuprofen was associated with integrin down-regulation, while naproxen and oxaprozin blocked the PI3K/Akt pathway. Both NSAID actions were independent of COX inhibition and PGE2 release. PMID:24597536

  10. Determining the Molecular Pathways Underlying the Protective Effect of Non-Steroidal Anti-Inflammatory Drugs for Alzheimer's Disease: A Bioinformatics Approach

    Full Text Available Alzheimer's disease (AD represents a substantial unmet need, due to increasing prevalence in an ageing society and the absence of a disease modifying therapy. Epidemiological evidence shows a protective effect of non steroidal anti inflammatory (NSAID drugs, and genome wide association studies (GWAS show consistent linkage to inflammatory pathways; both observations suggesting anti-inflammatory compounds might be effective in AD therapy although clinical trials to date have not been positive.In this study, we use pathway enrichment and fuzzy logic to identify pathways (KEGG database simultaneously affected in both AD and by NSAIDs (Sulindac, Piroxicam, Paracetamol, Naproxen, Nabumetone, Ketoprofen, Diclofenac and Aspirin. Gene expression signatures were derived for disease from both blood (n = 344 and post-mortem brain (n = 690, and for drugs from immortalised human cell lines exposed to drugs of interest as part of the Connectivity Map platform. Using this novel approach to combine datasets we find striking overlap between AD gene expression in blood and NSAID induced changes in KEGG pathways of Ribosome and Oxidative Phosphorylation. No overlap was found in non NSAID comparison drugs. In brain we find little such overlap, although Oxidative Phosphorylation approaches our pre-specified significance level.These findings suggest that NSAIDs might have a mode of action beyond inflammation and moreover that their therapeutic effects might be mediated in particular by alteration of Oxidative Phosphorylation and possibly the Ribosome pathway. Mining of such datasets might prove increasingly productive as they increase in size and richness. Keywords: Alzheimer's disease, NSAID, Inflammation, Fuzzy logic, Ribosome

  11. Non-Steroid Anti-Inflammatory Drugs Are Better than Acetaminophen on Fever Control at Acute Stage of Fracture.

    Full Text Available In addition to adequate surgical fixation and an aggressive rehabilitation program, pain relief is one of the most critical factors in the acute stage of fracture treatment. The most common analgesics are nonsteroid anti-inflammatory drugs and Acetaminophen, both of which relieve pain and reduce body temperature. In clinical experiences, they exhibit effective pain control; however, their influence on body temperature remains controversial. This study is aimed at determining the effects of analgesics at the acute stage of traumatic fracture by performing a clinical retrospective study of patients with fractures and a fracture animal model. The retrospective study revealed that, in the acetaminophen group, the mean value of postmedication body temperature (BT was significantly higher than that of the premedication BT. The change in BT was highly related with the medication rather than other risk factors. Forty eight 12-week-old male Wistar rats were divided into 6 groups: a control group, fracture group, fracture-Acetaminophen group, Acetaminophen group, fracture-Arcoxia group, and Arcoxia group. Fracture rats were prepared by breaking their unilateral tibia and fibula. Their inflammation conditions were evaluated by measuring their serum cytokine level and their physiological status was evaluated by estimating their central temperature, heart rate, and mean blood pressure. The hepatic adverse effects were assessed by measuring the serum levels of aspartate aminotransferase (sGOT and alanine aminotransferase (sGPT. The central temperature in the fracture-Acetaminophen group exceeded that in the groups fed normal saline water or Arcoxia. Accumulated hepatic injury was presented as steadily ascending curves of sGOT and sGPT. Inflammation-related cytokine levels were not higher in the Acetaminophen fracture group and were significantly lower in the fracture-Arcoxia group. Fever appeared to be aggravated by acetaminophen and more related to the

    Non-steroidal anti-inflammatory drugs (NSAIDs), including selective cyclo-oxygenase-2 (COX-2) inhibitors, cause upper gastrointestinal (GI) symptoms that are relieved by treatment with esomeprazole. We assessed esomeprazole for maintaining long-term relief of such symptoms. Six hundred and ten patients with a chronic condition requiring anti-inflammatory therapy who achieved relief of NSAID-associated symptoms of pain, discomfort, or burning in the upper abdomen during two previous studies were enrolled and randomly assigned into two identical, multicentre, parallel-group, placebo-controlled studies of esomeprazole 20 mg or 40 mg treatment (NASA2 [Nexium Anti-inflammatory Symptom Amelioration] and SPACE2 [Symptom Prevention by Acid Control with Esomeprazole] studies; ClinicalTrials.gov identifiers NCT00241514 and NCT00241553, respectively) performed at various rheumatology, gastroenterology, and primary care clinics. Four hundred and twenty-six patients completed the 6-month treatment period. The primary measure was the proportion of patients with relapse of upper GI symptoms, recorded in daily diary cards, after 6 months. Relapse was defined as moderate-to-severe upper GI symptoms (a score of more than or equal to 3 on a 7-grade scale) for 3 days or more in any 7-day period. Esomeprazole was significantly more effective than placebo in maintaining relief of upper GI symptoms throughout 6 months of treatment. Life-table estimates (95% confidence intervals) of the proportion of patients with relapse at 6 months (pooled population) were placebo, 39.1% (32.2% to 46.0%); esomeprazole 20 mg, 29.3% (22.3% to 36.2%) (p = 0.006 versus placebo); and esomeprazole 40 mg, 26.1% (19.4% to 32.9%) (p = 0.001 versus placebo). Patients on either non-selective NSAIDs or selective COX-2 inhibitors appeared to benefit. The frequency of adverse events was similar in the three groups. Esomeprazole maintains relief of NSAID-associated upper GI symptoms in patients taking continuous

    Non-steroidal anti-inflammatory drugs (NSAIDs) have been reported to be associated with adverse effects including kidney injury, while relevant studies from developing countries are limited. We aimed to explore the status of NSAIDs use in China, as well as cross-sectional association between NSAIDs intake and presence of chronic kidney disease (CKD). A national representative sample of 47,204 adults in China was used. Prevalence of regular NSAIDs use was reported. Age- and sex- matched controls of NSAIDs users were then selected. The association between NSAIDs use and kidney injury were analyzed using logistic regression. Altogether 1129 participants reported regular use of NSAIDs, with the adjusted prevalence of 3.6% (95% CI, 3.2%-3.9%). And 76.9% of them (n = 868) had taken phenacetin-containing analgesics, with an adjusted prevalence of 3.2% (95% CI, 2.9%-3.5%). After adjusting for potential confounders, long-term NSAIDs intake (≥ 48 months) was associated with eGFR < 60 mL/min per 1.73 m2, with an OR of 2.36 (95% CI, 1.28-4.37). Regular use of NSAIDs, especially phenacetin-containing drugs, is prevalent in China. And long-term NSAIDs intake (≥ 48 months) was independently associated with reduced renal function. © 2014 Asian Pacific Society of Nephrology.

    BACKGROUND Although Helicobacter pylori and non-steroidal anti-inflammatory drugs (NSAIDs) are the main causes of peptic ulcers disease (PUD), recently the prevalence of idiopathic peptic ulcer (IPU) is increasing in most parts of the world. The aim of this study was to assess the prevalence of IPU in Kerman, the center of largest province in south-east Iran. METHODS We included 215 patients with peptic ulcer in our study. Combined methods rapid urease test (RUT), histology, and real time polymerase chain reaction (PCR) was performed on endoscopic samples of peptic ulcers. NSAID use was determined by medical history. SPSS software version 16 was used for data analysis. p valuepeptic ulcer, four (1.8%) had H.pylorinegative and NSAID-negative PUD. There were not significant differences between patients with IPU and patients with peptic ulcer associated with H.pylori or NSAIDs regarding the sex, age, cigarette smoking, and opioid abuse. CONCLUSION Our study showed that in contrast to other reports from western and some Asian countries, the prevalence of IPU is low in Kerman and H.pylori infection is still the major cause of PUD. We recommend a large and multi-central study to determine the prevalence of IPU in Iran.

    The interaction of Cd(II) with the non-steroidal anti-inflammatory drug diclofenac sodium (Dic) leads to the formation of the complex [Cd2(L)41.5(MeOH)2(H2O)]n(L = Dic), 1, which has been isolated and structurally characterized by X-ray crystallography. Diclofenac sodium and its metal complex 1 have also been evaluated for antiproliferative activity in vitro against the cells of three human cancer cell lines, MCF-7 (breast cancer cell line), T24 (bladder cancer cell line), A-549 (non-small cell lung carcinoma), and a mouse fibroblast L-929 cell line. The results of cytotoxic activity in vitro expressed as IC50 values indicated the diclofenac sodium and cadmium chloride are non active or less active than the metal complex of diclofenac (1). Complex 1 was also found to be a more potent cytotoxic agent against T-24 and MCF-7 cancer cell lines than the prevalent benchmark metallodrug, cisplatin, under the same experimental conditions. The superoxide dismutase activity was measured by Fridovich test which showed that complex 1 shows a low value in comparison with Cu complexes. The binding properties of this complex to biomolecules, bovine or human serum albumin, are presented and evaluated. Antibacterial and growth inhibitory activity is also higher than that of the parent ligand compound.

  16. Non-steroidal anti-inflammatory drugs decrease E2F1 expression and inhibit cell growth in ovarian cancer cells.

    Blanca L Valle

    Full Text Available Epidemiological studies have shown that the regular use of non-steroidal anti-inflammatory (NSAIDs drugs is associated with a reduced risk of various cancers. In addition, in vitro and experiments in mouse models have demonstrated that NSAIDs decrease tumor initiation and/or progression of several cancers. However, there are limited preclinical studies investigating the effects of NSAIDs in ovarian cancer. Here, we have studied the effects of two NSAIDs, diclofenac and indomethacin, in ovarian cancer cell lines and in a xenograft mouse model. Diclofenac and indomethacin treatment decreased cell growth by inducing cell cycle arrest and apoptosis. In addition, diclofenac and indomethacin reduced tumor volume in a xenograft model of ovarian cancer. To identify possible molecular pathways mediating the effects of NSAID treatment in ovarian cancer, we performed microarray analysis of ovarian cancer cells treated with indomethacin or diclofenac. Interestingly, several of the genes found downregulated following diclofenac or indomethacin treatment are transcriptional target genes of E2F1. E2F1 was downregulated at the mRNA and protein level upon treatment with diclofenac and indomethacin, and overexpression of E2F1 rescued cells from the growth inhibitory effects of diclofenac and indomethacin. In conclusion, NSAIDs diclofenac and indomethacin exert an anti-proliferative effect in ovarian cancer in vitro and in vivo and the effects of NSAIDs may be mediated, in part, by downregulation of E2F1.

    We assessed the tolerance acquired by stream biofilms to two non-steroidal anti-inflammatory-drugs (NSAIDs), ibuprofen and diclofenac. Biofilms came from a stream system receiving the effluent of a wastewater treatment plant (WWTP). The response of biofilms from a non-polluted site (upstream the WWTP) was compared to that of others downstream with relevant and decreasing levels of NSAIDs. Experiments performed in the laboratory following the pollution-induced community tolerance (PICT) approach determined that both algae and microbial communities from biofilms of the sites exposed at the highest concentrations of ibuprofen and diclofenac acquired tolerance to the mixture of these NSAIDs occurring at the sites. It was also observed that the chronic pollution by the WWTP effluent affected the microbial metabolic profile, as well as the structure of the algal community. The low (at ng L(-1) level) but chronic inputs of pharmaceuticals to the river ecosystem result in tolerant communities of lower diversity and altered microbial metabolism.

    Green, Maggie; Norman, Kathleen E

    Purpose: To investigate Ontario physiotherapists' knowledge and use of, and attitudes toward, non-steroidal anti-inflammatory drugs (NSAIDs) to identify whether there is a need for physiotherapists to receive education specific to NSAIDs. Method: An existing survey instrument was modified and tested by five Ontario physiotherapists. The final version was distributed electronically to approximately 4,400 Ontario Physiotherapy Association members as a self-administered online questionnaire. Results: A total of 294 physiotherapists responded to the survey (response rate=6.7%). Respondents demonstrated variability in their knowledge of NSAID contraindications, side effects, and drug interactions. Most respondents (62.6%) were incorrect or unsure about where and how to obtain most NSAIDs, and most demonstrated incorrect or uncertain knowledge of the relevant legislation. Despite this lack of knowledge, 50% of respondents recommend NSAIDs to their patients. Conclusions: Many Ontario physiotherapists who participated in this survey recommend NSAIDs to their patients despite having a variable understanding of the legislation and medication-related factors. A lack of thorough knowledge of risks and contraindications has implications for patient safety. Physiotherapists who incorporate medications into their practice should access comprehensive information on appropriate NSAID use and should inform themselves about legislative restrictions to ensure that associated treatment is provided in a manner that is evidence based, safe, and in keeping with regulatory boundaries.

    Although large-scale population studies have shown that non-steroidal anti-inflammatory drugs (NSAIDs) increase the risk of myocardial infarction, this is not confirmed in patients with rheumatoid arthritis (RA). Herein, we review the litterature on the differential effects of NSAIDs on cardiovascular risk in osteoarthritis (OA) versus RA and discuss possible explanations for this discrepancy. To assess a potential additive effect of age in non-RA populations, we compared weighted mean age between RA patients and unselected NSAID users included in cohort and case-control studies that estimate the cardiovascular risk of NSAIDs, assuming that the main indication for NSAID usage in elderly populations is OA. Our hypothesis that advanced age in osteoarthtitis compared to RA patients confounds the effect of NSAIDs on cardiovasular risk was not confirmed. Several other hypotheses that can be proposed to explain this counterintuitive effect of NSAIDs on the cardiovascular risk of RA patients are discussed. We conclude that patients with RA have a lower cardiovascular disease risk associated with the use of NSAIDs, probably due to the nature of their disease per se, until further research indicates differently.

    Alzheimer disease is the most severe neurodegenerative disease worldwide. In the past years, a plethora of small molecules interfering with amyloid-β (Aβ) aggregation has been reported. However, their mode of interaction with amyloid fibers is not understood. Non-steroidal anti-inflammatory drugs (NSAIDs) are known γ-secretase modulators; they influence Aβ populations. It has been suggested that NSAIDs are pleiotrophic and can interact with more than one pathomechanism. Here we present a magic angle spinning solid-state NMR study demonstrating that the NSAID sulindac sulfide interacts specifically with Alzheimer disease Aβ fibrils. We find that sulindac sulfide does not induce drastic architectural changes in the fibrillar structure but intercalates between the two β-strands of the amyloid fibril and binds to hydrophobic cavities, which are found consistently in all analyzed structures. The characteristic Asp(23)-Lys(28) salt bridge is not affected upon interacting with sulindac sulfide. The primary binding site is located in the vicinity of residue Gly(33), a residue involved in Met(35) oxidation. The results presented here will assist the search for pharmacologically active molecules that can potentially be employed as lead structures to guide the design of small molecules for the treatment of Alzheimer disease. © 2015 by The American Society for Biochemistry and Molecular Biology, Inc.

    In the treatment of Parkinson's disease, potent disease-modifying drugs are still needed to halt progressive dopaminergic neurodegeneration. We have previously shown that meloxicam, an oxicam non-steroidal anti-inflammatory drug (NSAID), elicits a potent neuroprotective effect against 1-methyl-4-phenyl pyridinium (MPP(+))-induced toxicity in human dopaminergic SH-SY5Y neuroblastoma cells. This cyclooxygenase-independent neuroprotection of meloxicam is mediated via the phosphatidylinositol 3-kinase (PI3K)/Akt pathway; however, the specific chemical structure involved in inducing neuroprotection remains unresolved. In this study, we therefore investigated the structure-specific for eliciting the neuroprotective effect by examining a series of NSAIDs against MPP(+) toxicity in SH-SY5Y cells. Three oxicam-bearing NSAIDs showed potent neuroprotective effects, although none of the other 10 oxicam-nonbearing NSAIDs (3 salicylates, 6 coxibs and 1 polyphenol) or 3 piroxicam analogs (including ampiroxicam, a precursor of piroxicam) exerted any neuroprotection. Tenoxicam and piroxicam prevented MPP(+)-induced reduction of phosphorylated Akt levels in cells: a protective mechanism similar to that of meloxicam. Therefore, the oxicam structure was likely to be responsible for exhibiting the neuroprotection by sustaining survival-signaling in dopaminergic cells. The present results raise the possibility that the oxicam-bearing NSAIDs may serve as potential therapeutic drugs to retard or terminate progression of Parkinson's disease via a novel mechanism.

    Pharmaceuticals represent a major environmental concern since the knowledge on their occurrence, distribution and ecotoxicological potential is still limited particularly in coastal areas. In this study, bioaccumulation and cellular effects of various non steroidal anti-inflammatory drugs (NSAIDs) were investigated in mussels Mytilus galloprovincialis to reveal whether common molecules belonging to the same therapeutic class might cause different effects on non target organisms. Organisms exposed to environmental concentrations of acetaminophen (AMP), diclofenac (DIC), ibuprofen (IBU), ketoprofen (KET) and nimesulide (NIM) revealed a significant accumulation of DIC, IBU and NIM, while AMP and KET were always below detection limit. Nonetheless, for all tested NSAIDs, measurement of a large panel of ecotoxicological biomarkers highlighted impairment of immunological parameters, onset of genotoxicity and modulation of lipid metabolism, oxidative and neurotoxic effects. Laboratory results were integrated with a field study which provided the first evidence on the occurrence of DIC, IBU and NIM in tissues of wild mussels sampled during summer months from an unpolluted, touristic area of Central Adriatic Sea. Overall results demonstrated M. galloprovincialis as a good sentinel species for monitoring presence and ecotoxicological hazard of pharmaceuticals in the Mediterranean.

    We aimed to identify the signals that indicate the possible benefits of administering Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) at the initiation of meal, compared to immediately after food. This was a randomized, controlled, pilot study in 160 patients who received only NSAIDs for various pain conditions. Patients were randomized to Group I (control group) -NSAID After Food (AF), Group II-NSAID Before Food (BF), Group III-NSAID BF for 2 days and then crossed over to AF for next two days (CO-1) and Group IV-NSAID AF for 2 days and then crossed over to BF for next two days (C0-2 group). Group III & Group IV were given a washout period of 48 hours after the initial two days of treatment. All were followed up for the next 2 drug free days. Patients were observed for the development of gastritis (epigastric distress, epigastric pain, nausea, fullness of stomach, repeated reflux) throughout the study. Symptoms of gastritis were seen in 6.45% (2/31) and 36.11% (13/36) patients in group I and II, respectively. There was no statistically significant difference in the development of gastritis in AF group. However, statistically significant difference (Pgastritis. Administering NSAIDs at the initiation of meal is better tolerated as indicated by the lower incidence of gastritis. If proved in larger population, routine concurrent administration of medication for prevention of gastritis can be avoided.

    Non-steroidal anti-inflammatory drugs (NSAIDs) have come under scrutiny because of the gastrointestinal, renal and cardiovascular toxicity associated with prolonged use of these drugs. The purpose of this study was to identify molecular targets for NSAIDs related to cellular toxicity with a view to optimize drug efficacy in clinic. Coronary artery smooth muscle cells (CASMC) and endothelial cells (HCAEC) were treated with low (clinically achievable) and high (typically used in preclinical studies) concentrations of celecoxib (CXB), NS398 (NS) and ibuprofen (IBU) for 24h. NSAIDs-induced gene expression changes were evaluated by microarray analysis and validated by real-time RT-PCR and western blotting. The functional significance of differentially expressed genes was evaluated by Ingenuity Pathway Analysis (IPA). At high concentrations, NSAIDs altered the expression of genes regulating cell proliferation and cell death. NSAIDs also altered genes associated with cardiovascular functions including inflammation, thrombosis, fibrinolysis, coronary artery disease and hypertension. The gene expression was most impacted by IBU, CXB and NS, in that order. This study revealed that NSAIDs altered expression of an array of genes associated with cardiovascular events and emphasizes the potential for fingerprinting drugs in preclinical studies to assess the potential drug toxicity and to optimize the drug efficacy in clinical settings.

    A novel polyamidoamine dendrimer functionalized with Fe 3 O 4 nanoparticles (Fe 3 O 4 @PAMAM) had been fabricated and used as magnetic solid-phase extraction (MSPE) adsorbent. The Fe 3 O 4 @PAMAM nanocomposites were characterized by X-ray powder diffraction, Fourier transform infrared spectroscopy, field-emission scanning electron spectroscopy, elemental analytical, and thermal gravimetric analysis. The MSPE method coupled with high-performance liquid chromatography with an ultraviolet detection system was applied for the separation/analysis of non-steroidal anti-inflammatory drugs (NSAIDs). Major parameters affecting the extraction efficiency of the selected drugs were optimized. Under optimal conditions, the enrichment factors for the proposed method were 701835. The linear range, limit of detection, correlation coefficient (r), and relative standard deviation (RSD) were found to be 0.15-500 ng mL -1 , 0.050.08 ng mL -1 , 0.99320.9967, and 4.5-7.0% (n = 5, 0.2, 10 and 300 ng mL -1 ), respectively. The method was successfully applied to the determination of NSAIDs in the real water samples. The recoveries of spiked water samples were in the range of 93.6-98.9% with RSDs varying from 6.1% to 9.0%, showing the good accuracy of the method. Copyright © 2018 Elsevier B.V.

    The present study aimed to perform a systematic literature review to determine if there is a non-steroidal anti-inflammatory drug (NSAID) that interferes less within tooth movement. This research was performed according to the PRISMA statement. Articles were searched in eight electronic databases (PubMed, Scopus, Embase, Web of Science, LILACS, SciELO, Google Scholar, and Open Grey). Only experimental studies on male Wistar rats were selected, which included experiments related to the influence of NSAIDs on orthodontic movement. Studies in animals with pathological conditions, literature review articles, letters to the editor and/or editorials, case reports, abstracts, books, and book chapters were excluded. Each of the steps of this systematic literature review was performed by two examiners independently. the total sample consisted of 505 articles, from which 6 studies were eligible after a qualitative analysis. From the drugs assessed, paracetamol was unanimous for not interfering within orthodontic movement when compared to the control group. However, drugs such as aspirin, ibuprofen, sodium diclofenac, and selective cyclooxygenase-2 inhibitors caused a reduction in tooth movement when compared to the control group. paracetamol could be considered the drug of choice for pain relief because it interferes less within tooth movement.

    BACKGROUND The aim of this study was to evaluate the relationships of CYP2C9 and COX-2 genetic polymorphisms with therapeutic efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) in treatment of ankylosing spondylitis (AS). MATERIAL AND METHODS We enrolled 130 AS inpatients and outpatients in the Arthritis and Rheumatism Department of Peking University First Hospital and 106 healthy people getting routine check-ups between September 2013 and July 2014. CYP2C9 and COX-2 genetic polymorphisms were detected by PCR-RFLP. All AS patients underwent medical treatment and 12-week follow-up treatment. Score differences of BASDAI, ASAS20, ASAS50, and ASAS70 for AS patients with different genotypes before and after treatment were compared. RESULTS In terms of COX-2-1290A/G and -1195G/A gene polymorphism genotype and allele frequency, the case group and control group were obviously different (all P0.05). AS patients had improved BASDAI, ASAS20, ASAS50, and ASAS70 scores after they received NSAID treatment (all Ptreatment of AS and COX-2 gene -1290A/G and -1195G/A polymorphism were associated (all P0.05). CONCLUSIONS COX-2-1290A/G and -1195G/A polymorphism may increase AS risk and they both can be considered as biological indicators for prediction of efficacy of NSAIDs in treatment of AS.

    Non-steroidal anti-inflammatory drug, Diclofenac, targeting COX have shown promise in the treatment of Acanthamoeba keratitis, but the underlying mechanisms remain unknown. Using various NSAIDs, Diclofenac sodium, Indomethacin, and Acetaminophen, here we determined the effects of NSAIDs on the biological properties of Acanthamoeba castellanii belonging to the T4 genotype. Using amoebicidal assays, the results revealed that Diclofenac sodium, and Indomethacin affected growth of A. castellanii. In contrast, none of the compounds tested had any effect on the viability of A. castellanii. Importantly, all NSAIDs tested abolished A. castellanii encystation. This is a significant finding as the ability of amoebae to transform into the dormant cyst form presents a significant challenge in the successful treatment of infection. The NSAIDs inhibit production of cyclo-oxegenase, which regulates the synthesis of prostaglandins suggesting that cyclooxygenases (COX-1 and COX-2) and prostaglandins play significant role(s) in Acanthamoeba biology. As NSAIDs are routinely used in the clinical practice, these findings may help design improved preventative strategies and/or of therapeutic value to improve prognosis, when used in combination with other anti-amoebic drugs.

    Resident peritoneal macrophages exposed to inflammatory stimuli (zymosan, lipopolysaccharide (LPS)) represent a widely used model for studying arachidonic acid metabolism and for screening of prostaglandin (PG) synthesis inhibitors. In the present study, cyclooxygenase 1 (COX1) was shown constitutively expressed in mouse adherent and non-adherent macrophages whereas expression of COX2 was observed only in adherent cells, even when cultured in minimal conditions (Ca-, Mg- and serum-free medium). The COX2 expression was amplified by arachidonic acid cascade stimulating agents (Ca, Mg, zymosan) and by LPS in a time-dependant manner; PGE2 by itself amplified LPS-induced COX2 expression. In well-defined experimental conditions of COX2 expression (LPS-stimulated adherent macrophages), we studied specific interactions of some representative anti-inflammatory drugs with COX2 enzymatic activity and expression. By contrast with dexamethasone, which reduced PGE2 release together with a strong reduction of COX2 expression (protein and mRNA), non steroidal anti-inflammatory drugs (NSAIDs) reduced PGE2 synthesis without any effect at the COX2 mRNA level. This reduction of PGE2 production by NSAIDs resulted from either an exclusive enzymatic inhibition (aspirin, NS398, 6-Methoxy naphtyl acetic acid) or an enzymatic inhibition associated with a slight decrease of COX2 protein level (indomethacin). For paracetamol and salicylic acid, two weak inhibitors of COX enzymatic activity, reduction of PGE2 synthesis appeared to be related to reduced level of COX2. These findings show that the macrophage can be used as a cellular model to study specifically COX1 and COX2. In this cell type, COX2 expression is dependent on adhesion, enhanced by stimulation of arachidonic acid metabolism, and auto amplified by PGE2. Furthermore, the results indicate that known NSAIDs differ in their interaction with cyclooxygenase, being able to inhibit either COX2 enzymatic activity, and/or COX2 expression

    Human pharmaceuticals have been detected in the terrestrial environment at µg to mg kg(-1) concentrations. Repeated application of sewage sludge (biosolids) and increasing reclaimed wastewater use for irrigation could lead to accumulation of these novel contaminants in soil systems. Despite this, potential phytotoxicological effects on higher plants have rarely been evaluated. These studies aimed to test effects upon germination, development, growth and physiology of two crop plants, namely radish (Raphanus sativus Spakler 3) and lettuce (Lactuca sativa All Year Around), after exposure to different, but structurally related non-steroidal anti-inflammatory drugs (NSAIDs) at environmentally relevant concentrations. A range of biological endpoints comprising biomass, length, water content, specific root and shoot length, root to shoot ratio, daily progress of stages of cell elongation and organ emergence (primary root, hypocotyl elongation, cotyledon emergence, cotyledon opening, and no change), as well as photosynthetic measurements were evaluated. Compounds from the fenamic acid class were found to affect R. sativus root endpoints (root length and water content), while ibuprofen affected early root development of L. sativa. In general, phytotoxicological effects on root endpoints demonstrated that impacts upon higher plants are not only compound specific, but also differ between plant species. It was found that the usage of a wide range of biological endpoints (all simple, cost-effective and ecologically relevant) were beneficial in detecting differences in plant responses to NSAID exposure. Due to paucity and discrepancy within the few previously available phytotoxicological studies with pharmaceuticals, it is now essential to allocate time and resources to consider development of suitable chronic toxicity tests, and some suggestions regarding this are presented.

    Concomitant use of coumarines and non-steroidal anti-inflammatory drugs (NSAIDs) may induce bleeding complications, due to the inhibition of both coagulant factors and platelet function. Unlike non-selective NSAIDs, cyclo-oxygenase-2 (COX-2)-selective NSAIDs interfere very little with platelet aggregation. To determine whether COX-2-selective NSAIDs are associated with less bleeding complications in coumarine users, compared with non-selective NSAIDs. Prospective, nested case-control study. We studied concomitant coumarine and NSAID users over two years. Patients with bleeding (cases), and frequency-matched patients without bleeding (controls), were sent questionnaires regarding possible risk factors for bleeding. International normalized ratio (INR) values were recorded. Univariate and multivariate analyses were used to detect factors contributing to bleeding. There were 1491 reported bleeds. NSAIDs were involved in 14.8%; 3.9% involving COX-2-selective NSAIDs. In non-bleeders, 2601 prescriptions with a coumarine/NSAID combination were detected; 9.7% were COX-2-selective. Adjusted ORs (95% CI) for a bleeding complication were 3.07 (1.18-8.03) for non-selective NSAID use, 3.01 (1.42-6.37) for NSAID use > 1 month, and 1.89 (1.03-3.49) for INR > or = 4.0. In coumarine users, COX-2-selective NSAIDs are associated with less bleeding complications than non-selective NSAIDs are. Duration of NSAID use, as well as intensity of coumarine treatment, plays an important additional role. When the coumarine-NSAID combination is inevitable in an individual patient, a COX-2-selective NSAID may be preferred, with careful monitoring of the INR.

    The YacK gene from Yersinia enterocolitica strain 7, cloned in pET28a vector and expressed in Escherichia coli BL21 (DE3), showed laccase activity when oxidized with 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) and guaiacol. The recombinant laccase protein was purified and characterized biochemically with a molecular mass of ≈58 KDa on SDS-PAGE and showed positive zymogram with ABTS. The protein was highly robust with optimum pH 9.0 and stable at 70 °C upto 12 h with residual activity of 70%. Kinetic constants, K{sub m} values, for ABTS and guaiacol were 675 μM and 2070 μM, respectively, with corresponding Vmax values of 0.125 μmol/ml/min and 6500 μmol/ml/min. It also possess antioxidative property against BSA and Cu{sup 2+}/H{sub 2}O{sub 2} model system. Constant pH MD simulation studies at different protonation states of the system showed ABTS to be most stable at acidic pH, whereas, diclofenac at neutral pH. Interestingly, aspirin drifted out of the binding pocket at acidic and neutral pH, but showed stable binding at alkaline pH. The biotransformation of diclofenac and aspirin by laccase also corroborated the in silico results. This is the first report on biotransformation of non-steroidal anti-inflammatory drugs (NSAIDs) using recombinant laccase from gut bacteria, supported by in silico simulation studies. - Highlights: • Laccase from Yersinia enterocolitica strain 7 was expressed in Escherichia coli BL21 (DE3). • Recombinant laccase was found to be thermostable and alkali tolerant. • The in silico and experimental studied proves the biotransformation of NSAIDs. • Laccase binds to ligands differentially under different protonation state. • Laccase also possesses free radical scavenging property.

    Drug-drug interactions (DDIs) between antihypertensive drugs and non-steroidal anti-inflammatory drugs (NSAIDs) can lead to adverse drug reactions (ADRs). Guidelines are available to help prescribers deal with these drug associations, but their implementation is not well evaluated. The aims of this study were to assess the prevalence of NSAIDs exposure in patients treated with antihypertensive drugs, using the French Pharmacovigilance database, and explore the ADRs related to DDIs between antihypertensive drugs and NSAIDs. Over the 11, 442 notifications of ADRs recorded in this database in patients treated with oral antihypertensive drugs between 2008 and 2010, 517 (4.5 and 95% CI: 4.1-4.9) also included exposure to NSAIDs. These subjects were more frequently women, took more drugs in general, and were younger and less frequently treated with antiplatelet drugs. In 24.2% of them (125 patients), a DDI between NSAIDs and antihypertensive drugs was potentially the cause of the reported ADR. Acute renal failure caused by DDIs between NSAIDs and angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), or diuretics was the most frequently reported ADR (20.7%). Finally, in the French Pharmacovigilance database, around one-fourth of associations NSAIDs  +  antihypertensive drugs are associated with a 'serious' ADR (mainly acute renal failure), suggesting that this well-known DDI is not enough taken into account by prescribers. © 2012 The Authors Fundamental and Clinical Pharmacology © 2012 Société Française de Pharmacologie et de Thérapeutique.

    Full Text Available Abstract Background Cross national drug utilization studies can provide information about different influences on physician prescribing. This is important for medicines with issues around safety and quality of use, like non selective non-steroidal anti-inflammatory drugs (ns-NSAIDs and cyclo-oxygenase-2 (COX-2 inhibitors. To enable comparison of prescription medicine use across different jurisdictions with a range of population sizes, data first need to be compared within Australia to understand whether use in a smaller sub-population may be considered as representative of the total use within Australia. The aim of this study was to compare the utilization of non selective NSAID, COX-2 inhibitors and paracetamol between Queensland and Australia. Method Dispensing data were obtained for concession beneficiaries for Australia for ns-NSAIDs, COX-2 inhibitors and paracetamol subsidized by the PBS over the period 1997–2003. The same data were purchased for Queensland. Data were converted to Defined Daily Dose (DDD/1000 beneficiaries/day (World Health Organization anatomical therapeutic chemical classification, 2005. Results Total NSAID and paracetamol consumption were similar in Australia and Queensland. Ns-NSAID use decreased sharply with the introduction of COX-2 inhibitors (from approximately 80 to 40 DDD/1000 beneficiaries/day. Paracetamol was constant (approximately 45 DDD/1000 beneficiaries/day. COX-2 inhibitors consumption was initially higher in Queensland than in the whole of Australia. Conclusion Despite initial divergence in celecoxib use between Queensland and Australia, the use of ns-NSAIDs, COX-2 inhibitors and paracetamol overall, in concession beneficiaries, was comparable in Australia and Queensland.

    Full Text Available Abstract Background Recent data indicate that chronic use of coxibs leads to an increased occurrence of thrombotic cardiovascular events. This raises the question as to whether traditional non-steroidal anti-inflammatory drugs (tNSAIDs might also produce similar hazards. Our aim has been to evaluate the association between the chronic use of tNSAIDs and the risk of myocardial infarction (MI in patients. Methods We performed a nested case-control analysis with 4,975 cases of acute MI and 20,000 controls, frequency matched to cases by age, sex, and calendar year. Results Overall, current use of tNSAID was not associated with an increased risk of MI (RR:1.07;95%CI: 0.95–1.21. However, we found that the relative risk (RR of MI for durations of tNSAID treatment of >1 year was 1.21 (95% CI, 1.00–1.48. The corresponding RR was 1.34 (95% CI, 1.06–1.70 for non-fatal MI. The effect was independent from dose. The small risk associated with long-term use of tNSAIDs was observed among patients not taking low-dose aspirin (RR: 1.29; 95% CI, 1.01–1.65. The effect of long-term use for individual tNSAIDs ranged from a RR of 0.87 (95% CI, 0.47–1.62 with naproxen to 1.38 (95% CI, 1.00–1.90 with diclofenac. Conclusion This study adds support to the hypothesis that chronic treatment with some tNSAIDs is associated with a small increased risk of non-fatal MI. Our data are consistent with a substantial variability in cardiovascular risks between individual tNSAIDs.

    Full Text Available The release of reactive oxygen specie (ROS by activated neutrophil is involved in both the antimicrobial and deleterious effects in chronic inflammation. The objective of the present investigation was to determine the effect of therapeutic plasma concentrations of non-steroidal anti-inflammatory drugs (NSAIDs on the production of ROS by stimulated rat neutrophils. Diclofenac (3.6 µM, indomethacin (12 µM, naproxen (160 µM, piroxicam (13 µM, and tenoxicam (30 µM were incubated at 37ºC in PBS (10 mM, pH 7.4, for 30 min with rat neutrophils (1 x 10(6 cells/ml stimulated by phorbol-12-myristate-13-acetate (100 nM. The ROS production was measured by luminol and lucigenin-dependent chemiluminescence. Except for naproxen, NSAIDs reduced ROS production: 58 ± 2% diclofenac, 90 ± 2% indomethacin, 33 ± 3% piroxicam, and 45 ± 6% tenoxicam (N = 6. For the lucigenin assay, naproxen, piroxicam and tenoxicam were ineffective. For indomethacin the inhibition was 52 ± 5% and diclofenac showed amplification in the light emission of 181 ± 60% (N = 6. Using the myeloperoxidase (MPO/H2O2/luminol system, the effects of NSAIDs on MPO activity were also screened. We found that NSAIDs inhibited both the peroxidation and chlorinating activity of MPO as follows: diclofenac (36 ± 10, 45 ± 3%, indomethacin (97 ± 2, 100 ± 1%, naproxen (56 ± 8, 76 ± 3%, piroxicam (77 ± 5, 99 ± 1%, and tenoxicam (90 ± 2, 100 ± 1%, respectively (N = 3. These results show that therapeutic levels of NSAIDs are able to suppress the oxygen-dependent antimicrobial or oxidative functions of neutrophils by inhibiting the generation of hypochlorous acid.

    Our laboratory has previously demonstrated that peripheral inflammatory pain (PIP), induced by subcutaneous plantar injection of λ-carrageenan, results in increased expression and activity of the ATP-dependent efflux transporter P-glycoprotein (P-gp) that is endogenously expressed at the blood-brain barrier (BBB). The result of increased P-gp functional expression was a significant reduction in CNS uptake of morphine and, subsequently, reduced morphine analgesic efficacy. A major concern in the treatment of acute pain/inflammation is the potential for drug-drug interactions resulting from P-gp induction by therapeutic agents co-administered with opioids. Such effects on P-gp activity can profoundly modulate CNS distribution of opioid analgesics and alter analgesic efficacy. In this study, we examined the ability of diclofenac, a non-steroidal anti-inflammatory drug (NSAID) that is commonly administered in conjunction with the opioids during pain therapy, to alter BBB transport of morphine via P-gp and whether such changes in P-gp morphine transport could alter morphine analgesic efficacy. Administration of diclofenac reduced paw edema and thermal hyperalgesia in rats subjected to PIP, which is consistent with the known mechanism of action of this NSAID. Western blot analysis demonstrated an increase in P-gp expression in rat brain microvessels not only following PIP induction but also after diclofenac treatment alone. Additionally, in situ brain perfusion studies showed that both PIP and diclofenac treatment alone increased P-gp efflux activity resulting in decreased morphine brain uptake. Critically, morphine analgesia was significantly reduced in animals pretreated with diclofenac (3 h), as compared to animals administered diclofenac and morphine concurrently. These novel findings suggest that administration of diclofenac and P-gp substrate opioids during pain pharmacotherapy may result in a clinically significant drug-drug interaction. PMID:24520393

    Previous reports indicated that non-steroidal anti-inflammatory drugs (NSAIDs) suppress bone repair. Our previous study further found that ketorolac delayed the endochondral bone formation, and the critical effective timing was at the early stage of repair. Furthermore, we found that NSAIDs suppressed proliferation and induced cell death of cultured osteoblasts. In this study, we hypothesized that chondrocytic proliferation and death, which plays an important role at the early stage of endochondral bone formation, might be affected by NSAIDs. Non-selective NSAIDs, indomethacin, ketorolac, diclofenac and piroxicam; cyclooxygenase-2 (COX-2) selective NSAIDs, celecoxib and DFU (an analog of rofecoxib); prostaglandins (PGs), PGE1, PGE2 and PGF2α; and each NSAID plus each PG were tested. The effects of NSAIDs on proliferation, cell cycle kinetics, cytotoxicity and cell death of epiphyseal-articular chondrocytes of fetal rats were examined. The results showed that all the tested NSAIDs, except DFU, inhibited thymidine incorporation of chondrocytes at a concentration range (10 -8 to 10 -4 M) covering the theoretic therapeutic concentrations. Cell cycle was arrested by NSAIDs at the G /G 1 phase. Upon a 24 h treatment, LDH leakage and cell death (both apoptosis and necrosis) were significantly induced by the four non-selective NSAIDs in chondrocyte cultures. However, COX-2 inhibitors revealed non-significant effects on cytotoxicity of chondrocytes except higher concentration of celecoxib (10 -4 M). Replenishments of PGE1, PGE2 or PGF2α could not reverse the effects of NSAIDs on chondrocytic proliferation and cytotoxicity. In this study, we found that therapeutic concentrations of non-selective NSAIDs caused proliferation suppression and cell death of chondrocytes, suggesting these adverse effects may be one of the reasons that NSAIDs delay the endochondral ossification during bone repair found in previous studies. Furthermore, these effects of NSAIDs may act via PG

    Muscle injuries trigger an inflammatory process, releasing important biochemical markers for tissue regeneration. The use of non-steroidal anti-inflammatory drugs (NSAIDs) is the treatment of choice to promote pain relief due to muscle injury. NSAIDs exhibit several adverse effects and their efficacy is questionable. Photobiomodulation therapy (PBMT) has been demonstrated to effectively modulate inflammation induced from musculoskeletal disorders and may be used as an alternative to NSAIDs. Here, we assessed and compared the effects of different doses of PBMT and topical NSAIDs on biochemical parameters during an acute inflammatory process triggered by a controlled model of contusion-induced musculoskeletal injury in rats. Muscle injury was induced by trauma to the anterior tibial muscle of rats. After 1 h, rats were treated with PBMT (830 nm, continuous mode, 100 mW of power, 35.71 W/cm 2 ; 1, 3, and 9 J; 10, 30, and 90 s) or diclofenac sodium (1 g). Our results demonstrated that PBMT, 1 J (35.7 J/cm 2 ), 3 J (107.1 J/cm 2 ), and 9 J (321.4 J/cm 2 ) reduced the expression of tumor necrosis factor alpha (TNF-α) and cyclooxygenase-2 (COX-2) genes at all assessed times as compared to the injury and diclofenac groups (p NSAIDs in the modulation of the inflammatory process caused by muscle contusion injuries.

    Data concerning rates of gastrointestinal (GI) events in non-steroidal anti-inflammatory drug (NSAID) users derive mainly from clinical trials. The EVIDENCE study quantified the incidence of symptomatic uncomplicated and/or complicated GI events in at-risk European patients treated with NSAIDs in real-life practice. This non-interventional study assessed 4144 adults with at least one GI risk factor who recently initiated NSAID therapy for osteoarthritis (85%), rheumatoid arthritis (11%), ankylosing spondylitis (3%) or a combination (1%). Patient characteristics and medical history were collected from medical records. GI events (upper and lower) were recorded at in-clinic visits during 6 months' follow-up. Mean time on index NSAID at enrolment was 33 days. The incidence (per 100 person-years) was 18.5 per 100 person-years for uncomplicated GI events and 0.7 per 100 person-years for complicated GI events. Upper GI events were far more common (12%) than lower GI events (1%) during study follow-up (median 182 days (range 61-320)). Other reported rates for cardiovascular, anaemia or non-GI events were much less frequent. A minority (28%) of patients had ongoing proton pump inhibitor use at enrolment, with strong variation by practice and country. EVIDENCE is the largest prospective study of the real-life management of European patients treated with NSAIDs for rheumatic diseases and at increased GI risk. It shows that GI events from the upper GI tract are far more common than those from the lower GI tract. It also shows adherence to guidelines for gastroprotection is generally low. NCT01176682.

    We aimed to assess whether the use of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with an increased risk of cardiovascular (CV) events in stable patients with established atherothrombosis or multiple risk factors. We analysed the 23,728 European patients of the REACH Registry; 20,588 (86.8%) had established atherothrombotic disease and 3140 (13.2%) had multiple risk factors only. Aspirin (ASA) and/or NSAIDs use was determined at enrolment and ischemic events were recorded over two years of follow-up. cMACCE was defined as the composite of CV death, MI or stroke. Bleeding was defined as any bleeding leading to both hospitalisation and transfusion. The mean age of population was 67.2±9.8years. At baseline, 1573 patients (6.6%) received NSAIDs and 15,395 (64.9%) received ASA. Four groups were defined: 1) no ASA/no NSAIDs, 2) ASA only, 3) NSAIDs only, 4) NSAIDs+ASA, with 7722 (32.5%), 14,433 (60.8%), 611 (2.6%) and 962 (4.1%) patients in these groups, respectively. Among the 22,028 (92.8%) with complete 2-year follow-up, 683 (3.2%) died from CV causes, while 395 (1.9%) had MI, 665 (3.1%) stroke, 1651 (7.6%) cMACCE and 199 (1.0%) bleeding. After adjustment, NSAID use was independently associated with an increased risk of stroke (OR 1.635; 95% CI 1.239-2.159, pNSAID use and MI or MACCE. In stable atherothrombosis patients, the use of NSAIDs appears to be independently associated with an increased cerebrovascular event risk. Copyright © 2011 Elsevier Ireland Ltd.

    While detectable levels of non-steroidal anti-inflammatory drugs (NSAIDs) have been reported in various aquatic habitats, little is known about the mechanism of action of these pharmaceutical drugs on organisms. Recently we demonstrated that NSAIDs disrupt corticosteroidogenesis in rainbow trout (Oncorhynchus mykiss). As cortisol is a seawater adapting hormone, we hypothesized that exposure to NSAIDs will impair the hyposmoregulatory capacity of this species in seawater. Trout were exposed to either waterborne salicylate or ibuprofen in fresh water for four days and the salinity switched to 50% seawater for two days, followed by 100% seawater and sampled two days later. NSAIDs disturbed the seawater-induced elevation in plasma osmolality and concentrations of Cl(-) and K(+), but not Na(+) in rainbow trout. This was accompanied by enhanced gill glycolytic capacity and reduced liver glycogen content in seawater with NSAIDs, suggesting enhanced metabolic demand to fuel ion pumps. While salicylate did not affect gill Na(+)/K(+)-ATPase activity, ibuprofen inhibited the seawater-induced elevation in gill Na(+)/K(+)-ATPase activity. The drugs also further enhanced the seawater-induced elevation in plasma cortisol concentration; this response was greater with salicylate compared to ibuprofen. There were no changes in the transcript levels of key proteins involved in steroidogenesis with NSAIDs, whereas gill and brain GR protein expression expression was reduced with salicylate. Altogether, salicylate and ibuprofen exposures impaired the hyposmoregulatory capacity of rainbow trout in seawater, but the mode of action of the two drugs in bringing about these changes appears distinct in trout.

    Non-steroidal anti-inflammatory drugs (NSAIDs) induce the shedding of L-selectin in human neutrophils through a mechanism still not well understood. In this work we studied both the functional effect of NSAIDs on the neutrophils/endothelial cells dynamic interaction, and the potential involvement of reactive oxygen species (ROS) in the NSAIDs-mediated down-regulation of L-selectin. When human neutrophils were incubated with diclofenac, a significant reduction in the number of cells that rolled on activated endothelial cells was observed. Different NSAIDs (flufenamic acid, meclofenamic acid, diclofenac, indomethacin, nimesulide, flurbiprofen, meloxicam, phenylbutazone, piroxicam, ketoprofen and aspirin) caused variable increase in neutrophil intracellular ROS concentration, which was inversely proportional to the change produced in L-selectin surface expression. Pre-incubation of neutrophils with superoxide dismutase, but not with catalase, showed both a significant protective effect on the L-selectin down-regulation induced by several NSAIDs and a diminished effect of diclofenac on neutrophil rolling. Interestingly, diclofenac and flufenamic acid but not piroxicam significantly increased the extracellular superoxide anion production by neutrophils, and inhibition of nicotinamide adenine dinucleotide phosphate (NADPH)-oxidase activity with diphenyleneiodonium prevented the down-regulation of L-selectin by diclofenac. In accordance with these results, neutrophils from patients with chronic granulomatous disease, a hereditary disease in which neutrophils show a reduced capacity to form superoxide radicals, exhibited a lower down-regulation of L-selectin (IC50: 15.3 μg/ml) compared to normal controls (IC50: 5.6 μg/ml) in response to diclofenac. A group of NSAIDs is capable of interfering with the ability of neutrophils to interact with endothelial cells by triggering L-selectin-shedding through the NADPH-oxidase-dependent generation of superoxide anion at the plasma

    Low doses of aspirin (acetylsalicylic acid; ASA) and non-steroidal anti-inflammatory drugs (NSAIDs) increase the risk of gastrointestinal bleeding. GPBAR1 is a bile acid receptor expressed in the gastrointestinal tract. Here, we have investigated whether GPBAR1 was required for mucosal protection in models of gastrointestinal injury caused by ASA and NSAIDs. EXPERIMENTAL APPROCH: GPBAR1(+/+) and GPBAR1(-/-) mice were given ASA (10-50 mg.kg(-1)) or naproxen. Gastric and intestinal mucosal damage was assessed by measuring lesion scores. Expression of GPBAR1, mRNA and protein, was detected in mouse stomach. Mice lacking GPBAR1 were more sensitive to gastric and intestinal injury caused by ASA and NSAIDs and exhibited a markedly reduced expression of cystathionine-γ-liase (CSE), cystathionine-β-synthase (CBS) and endothelial NOS enzymes required for generation of H(2)S and NO, in the stomach. Treating GPBAR1(+/+) mice with two GPBAR1 agonists, ciprofloxacin and betulinic acid, rescued mice from gastric injury caused by ASA and NSAIDs. The protective effect of these agents was lost in GPBAR1(-/-) mice. Inhibition of CSE by DL-propargylglycine completely reversed protection afforded by ciprofloxacin in wild type mice, whereas treating mice with an H(2)S donor restored the protective effects of ciprofloxacin in GPBAR1(-/-) mice. Deletion of GPBAR1 altered the morphology of the small intestine and increased sensitivity to injury caused by naproxen. GPBAR1 is essential to maintain gastric and intestinal mucosal integrity. GPBAR1 agonists protect against gastrointestinal injury caused by ASA and NSAIDs by a COX-independent mechanism. © 2012 The Authors.

    Full Text Available In subjects with non-steroidal anti-inflammatory drugs (NSAIDs- exacerbated respiratory disease (NERD symptoms are triggered by acetyl salicylic acid (ASA and other strong COX-1 inhibitors, and in some cases by weak COX-1 or by selective COX-2 inhibitors. The mechanism involved is related to prostaglandin pathway inhibition and leukotriene release. Subjects who react to a single NSAID and tolerate others are considered selective responders, and often present urticaria and/or angioedema and anaphylaxis (SNIUAA. An immunological mechanism is implicated in these reactions. However, anecdotal evidence suggests that selective responders who present respiratory airway symptoms may also exist.Our objective was to determine if subjects might develop selective responses to NSAIDs/paracetamol that manifest as upper/lower airways respiratory symptoms. For this purpose we studied patients reporting asthma and/or rhinitis induced by paracetamol or a single NSAID that tolerated ASA. An allergological evaluation plus controlled challenge with ASA was carried out. If ASA tolerance was found, we proceeded with an oral challenge with the culprit drug. The appearance of symptoms was monitored by a clinical questionnaire and by measuring FEV1 and/or nasal airways volume changes pre and post challenge. From a total of 21 initial cases, we confirmed the appearance of nasal and/or bronchial manifestations in ten, characterised by a significant decrease in FEV1% and/or a decrease in nasal volume cavity after drug administration. All cases tolerated ASA.This shows that ASA tolerant subjects with asthma and/or rhinitis induced by paracetamol or a single NSAID without skin/systemic manifestations exist. Whether these patients represent a new clinical phenotype to be included within the current classification of hypersensitivity reactions to NSAIDs requires further investigation.

    Background Since use of non-steroidal anti-inflammatory drugs (NSAIDs) during pregnancy is common, small increases in the risk of birth defects may have significant implications for public health. Results of human studies on the teratogenic risks of NSAIDs are inconsistent. Therefore, we evaluated the risk of selected birth defects after prenatal exposure to prescribed and over-the-counter NSAIDs. Methods and Findings We used data on 69,929 women enrolled in the Norwegian Mother and Child Cohort Study between 1999 and 2006. Data on NSAID exposure were available from a self-administered questionnaire completed around gestational week 17. Information on pregnancy outcome was obtained from the Medical Birth Registry of Norway. Only birth defects suspected to be associated with NSAID exposure based upon proposed teratogenic mechanisms and previous studies were included in the multivariable logistic regression analyses. A total of 3,023 women used NSAIDs in gestational weeks 0–12 and 64,074 women did not report NSAID use in early pregnancy. No associations were observed between overall exposure to NSAIDs during pregnancy and the selected birth defects separately or as a group (adjusted odds ratio 0.7, 95% confidence interval 0.4–1.1). Associations between maternal use of specific types of NSAIDs and the selected birth defects were not found either, although an increased risk was seen for septal defects and exposure to multiple NSAIDs based on small numbers (2 exposed cases; crude odds ratio 3.9, 95% confidence interval 0.9–15.7). Conclusions Exposure to NSAIDs during the first 12 weeks of gestation does not seem to be associated with an increased risk of the selected birth defects. However, due to the small numbers of NSAID-exposed infants for the individual birth defect categories, increases in the risks of specific birth defects could not be excluded. PMID:21789231

    Low doses of acetyl salicylic acid (ASA) and non-steroidal anti-inflammatory drugs (NSAIDs) cause gastrointestinal damage. The farnesoid X receptor (FXR) is a bile acid sensor essential for maintenance of intestinal homeostasis. Here, we have investigated whether FXR is required for mucosal protection in models of gastrointestinal injury caused by ASA and NSAIDs and if FXR activation has potential in the treatment or prevention of gastrointestinal injury caused by these agents. FXR(+/+) and FXR(-/-) mice were given ASA (10 to 100 mg·kg(-1) ) or NSAIDs. Gastric and intestinal mucosal damage assessed by measuring lesion scores. FXR were activated by giving mice natural (chenodeoxycholic acid; CDCA) or synthetic (GW4064) FXR agonists. FXR, mRNA and protein, was detected in human and mouse stomach. FXR(-/-) mice were more prone to develop severe gastric and intestinal injury in response to ASA and NSAIDs and showed a severe reduction in the gastrointestinal expression of cystathionine-γ-lyase (CSE), an enzyme required for generation of hydrogen sulphide. CSE expression was reduced by ≈50% in wild-type mice challenged with ASA. Treating wild-type mice but not FXR(-/-) mice with CDCA or GW4064 protected against gastric injury caused by ASA and NSAIDs, by a CSE-dependent and cycloxygenase- and NO-independent, mechanism. FXR activation by GW4064 rescued mice from intestinal injury caused by naproxen. FXR was essential to maintain gastric and intestinal mucosal barriers. FXR agonists protected against gastric injury caused by ASA and NSAIDs by a CSE-mediated mechanism. © 2011 The Authors. British Journal of Pharmacology © 2011 The British Pharmacological Society.

    The transporter-mediated uptake of drugs from blood into hepatocytes is a prerequisite for intrahepatic drug action or intracellular drug metabolism before excretion. Therefore, uptake transporters, e.g., members of the organic anion transporting polypeptide (OATP) family are important determinants of drug pharmacokinetics. Highly and almost exclusively expressed in hepatocytes are the OATP family members OATP1B1 (SLCO1B1) and OATP1B3 (SLCO1B3). Drug substrates of OATP1B1 and OATP1B3 include antibiotics and HMG-CoA reductase inhibitors (statins). It has been demonstrated that administration of two or more drugs that are substrates for these hepatic uptake transporters may lead to transporter-mediated drug-drug interactions, resulting in altered transport kinetics for drug substrates. In this study we investigated whether non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol interact with OATP1B1 and OATP1B3 using the standard substrate BSP and the drug substrate pravastatin. Using human embryonic kidney cells stably expressing OATP1B1 or OATP1B3, we demonstrated that bromosulfophthalein uptake was inhibited by diclofenac, ibuprofen. and lumiracoxib. Of interest, pravastatin uptake was stimulated by these NSAIDs, and for ibuprofen we determined activation constants (EC₅₀ values) of 64.0 and 93.1 μM for OATP1B1- and OATP1B3-mediated uptake, respectively. Furthermore, we investigated whether NSAIDs were also substrates for OATP1B1 and OATP1B3 and demonstrated that only diclofenac was significantly transported by OATP1B3, whereas all other NSAIDs investigated were not substrates for these uptake transporters. These results demonstrated that drugs may interact with transport proteins by allosteric mechanisms without being substrates and, therefore, not only uptake inhibition but also allosteric-induced modulation of transport function may be an important mechanism in transporter-mediated drug-drug interactions.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are the sixth top-selling drugs worldwide and are commonly found in freshwater ecosystems in the high ng/l to low μg/l range. Recent studies have investigated both the acute and the chronic toxicity of single NSAIDs on different biological models, but these studies have completely neglected the fact that, in the environment, non-target organisms are exposed to mixtures of drugs that have unforeseeable toxicological behavior. This work investigated the sub-lethal effects induced by a mixture of three common NSAIDs, namely, diclofenac, ibuprofen and paracetamol, on the freshwater bivalve, the zebra mussel (Dreissena polymorpha). The mussels were exposed to three different environmental concentrations of the mixture (Low, Mid and High). A multi-biomarker approach was used to highlight cyto-genotoxic effects and the imbalance of the oxidative status of the treated specimens. The Neutral Red Retention Assay (NRRA) was used as a biomarker of cytotoxicity, whereas the activities of catalase, superoxide dismutase, glutathione peroxidase and glutathione S-transferase were measured to assess the role played by the oxidative stress enzymes. In addition, the single cell gel electrophoresis assay, the DNA Diffusion assay and the micronucleus test were used to investigate possible genotoxic effects. According to our NRRA results, each treatment was able to induce a significant cellular stress in bivalves, probably due to the raise of oxidative stress, as indicated by the alteration of enzyme activities measured in treated specimens. Moreover, the mixture induced significant enhancements of DNA fragmentation, which preluded fixed genetic damage, as highlighted by the increase of both apoptotic and micronucleated cells.

    Pharmaceuticals are becoming widely distributed in waters and wastewaters and pose a serious threat to public health. The present study aimed to analyze non-steroidal anti-inflammatory drugs (NSAIDs) in surface waters, drinking water, and wastewater in Tehran, Iran. Thirty-six samples were collected from surface waters, tap water, and influent and effluent of municipal and hospital wastewater treatment plants (WWTP). A solid-phase extraction (SPE) followed by liquid chromatography-tandem mass spectrometry method was used for the determination of pharmaceuticals, namely ibuprofen (IBP), naproxen (NPX), diclofenac (DIC), and indomethacin (IDM). IBP was found in most of the samples and had the highest concentration. The highest concentrations of NSAIDs were found in the municipal WWTP influents and hospital WWTP effluents. In the municipal WWTP influent samples, the concentrations of IBP, NPX, DIC, and IDM were 1.05, 0.43, 0.23, and 0.11 μg/L, respectively. DIC was found only in one river sample. All NSAIDs were detected in tap water samples. However, their concentration was very low and the maximum values for IBP, NPX, DIC, and IDM were 47, 39, 24, and 37 ng/L, respectively, in tap water samples. Results showed that the measured pharmaceuticals were detected in all rivers with low concentrations in nanograms per liter range, except DIC which was found only in one river. Furthermore, this study showed that the aforementioned pharmaceuticals are not completely removed during their passage through WWTPs. A potential environmental risk of selected NSAIDs for the urban wastewater has been discussed. However, given their low measured concentrations, no ecotoxicological effect is suspected to occur.

    To evaluate the associations of non-steroidal anti-inflammatory drug (NSAID) use with risk of erectile dysfunction (ED), considering the indications for NSAID use. We analysed data from 4 726 men in the placebo arm of the Prostate Cancer Prevention Trial (PCPT) without evidence of ED at baseline. Incident ED was defined as mild/moderate (decrease in normal function) or severe (absence of function). Proportional hazards models were used to estimate the covariate-adjusted associations of NSAID-related medical conditions and time-dependent NSAID use with ED risk. Arthritis (hazard ratio [HR] 1.56), chronic musculoskeletal pain (HR 1.35), general musculoskeletal complaints (HR 1.36), headaches (HR 1.44), sciatica (HR 1.50) and atherosclerotic disease (HR 1.60) were all significantly associated with an increased risk of mild/moderate ED, while only general musculoskeletal complaints (HR 1.22), headaches (HR 1.47) and atherosclerotic disease (HR 1.60) were associated with an increased risk of severe ED. Non-aspirin NSAID use was associated with an increased risk of mild/moderate ED (HR 1.16; P = 0.02) and aspirin use was associated with an increased risk of severe ED (HR 1.16; P = 0.03, respectively). The associations of NSAID use with ED risk were attenuated after controlling for indications for NSAID use. The modest associations of NSAID use with ED risk in the present cohort were probably attributable to confounding indications for NSAID use. NSAID use was not associated with ED risk. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

    A new sol-gel hybrid material, methyltrimethoxysilane-cyanopropyltriethoxysilane (MTMOS-CNPrTEOS) was successfully synthesized and used as a coating material in stir bar sorptive extraction (SBSE) of selected non-steroidal anti-inflammatory drugs (NSAIDs) in urine samples. The MTMOS-CNPrTEOS hybrid was synthesized by hydrolysis and condensation of MTMOS and CNPrTEOS in the presence of trifluoroacetic acid as catalyst via sol-gel method. Several factors influencing the synthesized sol-gel hybrid MTMOS-CNPrTEOS process such as mole ratio of MTMOS-CNPrTEOS, NaOH concentrations as etching solution, etching time, coating time and water content were investigated and optimized in this study. The optimum synthesis conditions obtained were 1:1 mol ratio of MTMOS-CNPrTEOS, 1 M NaOH as etching solution, 60 min etching time, 2 h coating time and 6 mmol water. The sol-gel hybrid MTMOS-CNPrTEOS synthesized under the optimum conditions was used to determine selected NSAIDs in human urine samples using normal stacking mode capillary electrophoresis with ultraviolet detection. MTMOS-CNPrTEOS SBSE method demonstrated good linearity (60 to 20,000 μg L -1 ) with excellent coefficient of determination (r 2 > 0.9990). The sol-gel hybrid MTMOS-CNPrTEOS SBSE method showed low limit of detection (35 - 41 μg L -1 ) with good precision (RSD < 6 %, n = 3) and excellent extraction recoveries (83.5 - 98.9 %) for the selected NSAIDs. The sol-gel hybrid MTMOS-CNPrTEOS SBSE method demonstrated good potential as an alternative sorbent in SBSE method for NSAIDs. (author)

    To evaluate whether subjects with knee or hip osteoarthritis (OA) pain on non-steroidal anti-inflammatory drugs (NSAIDs) received greater benefit when tanezumab monotherapy replaced or was coadministered with NSAIDs. Subjects (N=2700) received intravenous tanezumab (5 or 10 mg) or placebo every 8 weeks with or without oral naproxen 500 mg twice daily or celecoxib 100 mg twice daily. Efficacy was assessed as change from baseline to week 16 in three co-primary endpoints: Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain, WOMAC Physical Function and Patient's Global Assessment (PGA) of OA. Safety assessments included adverse events, physical and neurological examinations, laboratory tests and vital signs. Although all tanezumab treatments provided significant improvements in WOMAC Pain and Physical Function over either NSAID alone, only tanezumab+NSAIDs were significant versus NSAIDs with PGA and met the prespecified definition of superiority. Combination treatment did not substantially improve pain or function over tanezumab monotherapy. Adverse event frequency was higher with tanezumab than with NSAIDs and highest with combination therapy. Higher incidence of all-cause total joint replacements occurred with tanezumab+NSAID versus tanezumab monotherapy or NSAIDs. Rapidly progressive OA incidence was significantly greater versus NSAID in all tanezumab groups except tanezumab 5 mg monotherapy. Subjects receiving partial symptomatic relief of OA pain with NSAIDs may receive greater benefit with tanezumab monotherapy. While only coadministration of tanezumab with NSAIDs met the definition of superiority, combination treatment did not provide important benefits over tanezumab monotherapy; small differences in efficacy were negated by treatment-limiting or irreversible safety outcomes.

    Full Text Available Abstract Background The aims of the present study were first to detect MCID for WOMAC in a Moroccan population, and second, to identify the best pre-treatment predictors on the change of health after treatment by non-specific, non-steroidal anti-inflammatory drugs (NSAIDs, and to evaluate whether the predictors were dependent on the choice of the response criterion. Methods The study involved 173 patients with osteoarthritis in whom primary care physicians decided to start treatment with non-selective NSAIDs. Assessments at admission and after 6 weeks were conducted. In order to determine the threshold levels associated with a definition of clinically important improvement, the receiver operating characteristic method was used. Three different measures of response to a 6-week NSAIDs treatment were used: one indirect measure (MCID in the total WOMAC score, one direct measure (transition question and a combination of both criteria. Results Eighty patients (46.3% reported "a slightly better" general health status compared to that of 6 weeks before NSAIDs treatment. The MCID proportion is a 16.0% reduction in WOMAC. The most stable pre-treatment predictors on the improvement of health after treatment by NSAIDs were the absence of previous knee injury and a high level of education. Conclusions In our data, a 16.0% reduction of the total WOMAC score from baseline was associated with the highest degree of improvement on the transition scale category. This cut-off point had good accuracy, and should be appropriate for use in the interpretation of clinical studies results, as well as in clinical care.

    Full Text Available Non-steroidal anti-inflammatory agents (NSAIDs are known to be associated with renal damage. No clear evidence exists regarding differential risk of chronic kidney disease (CKD, specifically, across various NSAIDs.The aim of this population-based case-control study was to evaluate the association between use of individual NSAIDs and risk of CKD in a general population of Southern Italy.A nested case-control study was carried out using the general practice Arianna database, identifying incident CKD patients as cases and matched controls from 2006 to 2011. The date of first CKD diagnosis was defined as the index date (ID. Conditional logistic regressions were performed to estimate the risk of CKD associated with NSAIDs by class and individual drugs as compared to non-use during different time windows (within one year, six or three months prior to ID, with the latter being defined as current users. Among current users, the effect of cumulative exposure to these drugs was evaluated.Overall, 1,989 CKD cases and 7,906 matched controls were identified. A statistically significant increase in the risk of CKD was found for current users of oxicams (adjusted OR: 1.68; 95% CI: 1.15-2.44 and concerning individual compounds, for ketorolac (adj. OR: 2.54; 95% CI: 1.45-4.44, meloxicam (adj. OR: 1.98; 95% CI: 1.01-3.87 and piroxicam (adj. OR: 1.95; 95% CI: 1.19-3.21.The risk of CKD varies across individual NSAIDs. Increased risk has been found for ketorolac, which may precipitate subclinical CKD through acute renal damage, and long-term exposure to oxicams, especially meloxicam and piroxicam.

    Full Text Available BACKGROUND: Drug-Drug Interactions between Non Steroidal Anti-Inflammatory Drugs (NSAIDs and Angiotensin Converting Enzyme Inhibitors (ACEIs, Angiotensin Receptor Blocker (ARBs or diuretics can lead to renal failure and hyperkalemia. Thus, monitoring of serum creatinine and potassium is recommended when a first dispensing of NSAID occur in patients treated with these drugs. METHODS: We conducted a pharmacoepidemiological retrospective cohort study using data from the French Health Insurance Reimbursement Database to evaluate the proportion of serum creatinine and potassium laboratory monitoring in patients treated with ACEI, ARB or diuretic and receiving a first dispensing of NSAID. We described the first dispensing of NSAID among 3,500 patients of a 4-year cohort (6,633 patients treated with antihypertensive drugs and analyzed serum creatinine and potassium laboratory monitoring within the 3 weeks after the first NSAID dispensing. RESULTS: General Practitioners were the most frequent prescribers of NSAIDs (85.5%, 95% CI: 84.3-86.6. The more commonly prescribed NSAIDs were ibuprofen (20%, ketoprofen (15%, diclofenac (15% and piroxicam (12%. Serum creatinine and potassium monitoring was 10.7% (95% CI: 9.5-11.8 in patients treated by ACEIs, ARBs or diuretics. Overall, monitoring was more frequently performed to women aged over 60, treated with digoxin or glucose lowering drugs, but not to patients treated with ACEIs, ARBs or diuretics. Monitoring was more frequent when NSAIDs' prescribers were cardiologists or anesthesiologists. CONCLUSION: Monitoring of serum creatinine and potassium of patients treated with ACEIs, ARBs or diuretics and receiving a first NSAID dispensing is insufficiently performed and needs to be reinforced through specific interventions.

    To determine in retrospective data the prevalence at hospital discharge of co-prescribing angiotensin-converting enzyme inhibitors (ACE-I) and non-steroidal anti-inflammatory drugs (NSAIDs) and ACE-I/NSAIDs and diuretics and to identify factors associated with the co-prescription. Secondary, we evaluated the extent of serum creatinine and potassium monitoring in patients treated with ACE-I and these associations and determined the prevalence of values above the upper normal limit (UNL) in monitored patients. Hospitalized patients with ACE-I in their therapy at discharge were included in 3 groups as follows: ACE-I, DT (double therapy with ACE-I and NSAIDs) and TT (triple therapy with ACE-I, NSAIDs and diuretics) groups. We evaluated differences on demographic characteristics, co-morbidities, medications, laboratory monitoring and quantified the patients with serum creatinine and potassium levels above the UNL using descriptive statistics. Logistic regression analysis with backward elimination was performed to identify significant predictors of combination therapy. Of 9960 admitted patients, 1214 were prescribed ACE-I, 40 were prescribed ACE-I/NSAIDs and 22 were prescribed ACE-I/NSAIDs/diuretics (3.13% and 1.72%, respectively, of the patients prescribed with ACE-I). Serum creatinine and potassium were monitored for the great majority of patients from all groups. The highest percentage of hyperkalemia was found in the DT group (10% of the patients) and of serum creatinine above UNL in the TT group (45.45%). The logistic regression final model showed that younger patients and monitoring for potassium were significantly associated with combination therapy. The prevalence of patients receiving DT/TT was relatively low and their monitoring during hospitalization was high. Factors associated with the combinations were younger patients and patients not tested for serum potassium.

    We comprehensively reviewed the published scientific literature on non-steroidal anti-inflammatory drugs (NSAIDs) and cancer and evaluated results based upon epidemiologic criteria of judgment: consistency of results, strength of association, dose response, molecular specificity, and biological plausibility. Sufficient data from 91 epidemiologic studies were available to examine the dose response of relative risk and level of NSAID intake for ten human malignancies. Dose response curves were fitted by exponential regression. Results showed a significant exponential decline in the risk with increasing intake of NSAIDs (primarily aspirin or ibuprofen) for 7-10 malignancies including the four major types: colon, breast, lung, and prostate cancer. Daily intake of NSAIDs, primarily aspirin, produced risk reductions of 63% for colon, 39% for breast, 36% for lung, and 39% for prostate cancer. Significant risk reductions were also observed for esophageal (73%), stomach (62%), and ovarian cancer (47%). NSAID effects became apparent after five or more years of use and were stronger with longer duration. Observed protective effects were also consistently stronger for gastrointestinal malignancies (esophagus, stomach, and colon). Results for pancreatic, urinary bladder, and renal cancer were inconsistent. Initial epidemiologic studies of malignant melanoma, Hodgkin's disease, and adult leukemia also found that NSAIDs are protective. A few studies suggest that ibuprofen has stronger anticancer effects than aspirin, particularly against breast and lung cancer. Overexpression of cyclooxygenase-2 (COX-2) and increased prostaglandin biosynthesis correlates with carcinogenesis and metastasis at most anatomic sites. Preclinical investigations provide consistent evidence that both selective and non-selective NSAIDs effectively inhibit chemically-induced carcinogenesis of epithelial tumors. This review provides compelling and converging evidence that regular intake of NSAIDs that non

    Benzydamine (BZY) is a non-steroidal anti-inflammatory drug used for the topical treatment of inflammations of the oral and vaginal mucosae. Virtually nothing is known about the central pharmacological actions of BZY. Yet there are reports of voluntary systemic overdosage of BZY in drug addicts, resulting in a euphoric, hallucinatory state. In the present study, we investigated the reinforcing properties of BZY in a rat self-administration paradigm. We found that BZY has a powerful reinforcing effect and that this effect is greatly facilitated in animals that already had substance experience, having previously self-administered heroin and cocaine, indicating cross sensitization between BZY and other common drugs of abuse. We then assessed the effect of BZY on prelimbic cortex-to-nucleus accumbens glutamatergic transmission, using field recordings in rat parasagittal brain slices. BZY dose-dependently reduced both field excitatory post synaptic potential amplitude and paired pulse ratio, suggesting a presynaptic mechanism of action. Similarly to the in vivo paradigm, also the electrophysiological effects of BZY were potentiated in slices from animals that had undergone cocaine and heroin self-administration. Furthermore, BZY-induced Long Term Depression (LTD)-like responses in the prelimbic cortex-to-nucleus accumbens circuitry were significantly reduced in the presence of the CB1 receptor antagonist AM251. These findings provide firm evidence of the abuse liability of BZY and suggest a possible cannabinoidergic mechanism of action. Further research is needed in order to give insights into the molecular mechanism underlying BZY psychoactive and reinforcing effects, to better understand its abuse potential. © 2017 Society for the Study of Addiction.

    In this study, for the first time, 2-aminobenzothiazole monomer was polymerized on Fe3O4 NPs, graphene oxide/Fe3O4 (GO/Fe3O4) and graphene/Fe3O4 (G/Fe3O4) nanocomposites. The synthesized magnetic nanosorbents were characterized by various techniques. The extraction ability of these nanosorbents including Fe3O4, GO/Fe3O4, G/Fe3O4, Fe3O4@poly(2-aminobenzothiazole) (Fe3O4@PABT), GO/Fe3O4@PABT and G/Fe3O4@PABT were compared for dispersive-micro-solid phase extraction of three non-steroidal anti-inflammatory drugs. The results revealed that GO/Fe3O4@PABT nanocomposite demonstrates higher extraction efficiency for naproxen, diclofenac and ibuprofen as selected model analytes. Following the sorption and elution steps, the model analytes were quantified by high performance liquid chromatography-photo diode array detection. Afterwards, a central composite design methodology combined with desirability function approach was applied to find out the optimal experimental conditions. Under the optimized conditions, the limits of detection and linear dynamic ranges were achieved in the range of 0.07-0.3 μg L(-1) and 0.25-2000 μg L(-1), respectively. The percent of extraction recovery was 87.4, 85.5 and 90.5% for naproxen, diclofenac and ibuprofen, respectively. The obtained relative standard deviation (n=5) was 7.2, 5.4 and 6.4% for naproxen, diclofenac and ibuprofen, respectively. Ultimately, this method was employed for urinary monitoring of the target analytes and satisfactory results were obtained. Copyright © 2016 Elsevier B.V. All rights reserved.

    Endocrine disrupting chemicals and non-steroidal anti-inflammatory drugs are two important groups of emerging pollutants due to their toxicological and chemical characteristics and their persistent detection in the aquatic environment. Wastewater treatment plants are a significant pathway for their transfer to the water courses. It is well evidenced that these chemicals are only partially removed through biological treatment of wastewater and therefore being detected in secondary effluents. This work focuses on the evaluation of the efficiency of two well-established disinfection technologies (chlorination and UV irradiation) along with UV/H2O2 and powdered activated carbon (PAC) to remove these chemicals from biologically treated wastewater. Based on the results it is shown that appreciable removal efficiencies due to chlorination should be expected for most of the target compounds, whereas this was not the case for ibuprofen and ketoprofen. With the exemption of diclofenac and ketoprofen direct UV irradiation did not efficiently removed target compounds for UV doses usually applied for disinfection purposes. The application of advanced UV treatment through the addition of H2O2 although resulted in increased removal of the target compounds is not sufficient at moderate UV and H2O2 doses to achieve satisfactory removal efficiencies. PAC use resulted in sufficient removal of target compounds although high PAC doses were required for some chemicals. Comparison of Freundlich isotherms of this study with those of other studies, derived employing water samples, suggested that the water matrix along with the target compounds concentration range can significantly affect the outcome of the experiments.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are the most consumed drugs worldwide because of their efficacy and utility in the treatment of pain and inflammatory diseases. However, they are also responsible for an important number of adverse effects including hypersensitivity reactions. The most important group of these reactions is triggered by non-immunological, pharmacological mechanisms catalogued under the denomination of cross-intolerance (CRI), with acute urticaria/angioedema induced by multiple NSAIDs (MNSAID-UA) the most frequently associated clinical entity. A recent genome-wide association study identified the gene encoding the centrosomal protein of 68 KDa (CEP68) as the major locus associated with aspirin intolerance susceptibility in asthmatics. In this study, we aimed to assess the role of this locus in susceptibility to CRI to NSAIDs by examining 53 common gene variants in a total of 635 patients that were classified as MNSAID-UA (n = 399), airway exacerbations (n = 110) or blended pattern (n = 126), and 425 controls. We found in the MNSAID-UA group a number of variants (17) associated (lowest p-value = 1.13×10−6), including the non-synonymous Gly74Ser variant (rs7572857) previously associated with aspirin intolerance susceptibility in asthmatics. Although not being significant in the context of multiple testing, eight of these variants were also associated with exacerbated respiratory disease or blended reactions. Our results suggest that CEP68 gene variants may play an important role in MNSAID-UA susceptibility and, despite the different regulatory mechanisms involved depending on the specific affected organ, in the development of hypersensitivity reactions to NSAIDs.

    Despite all the technological advances in orthodontics, orthodontic treatment still seems to involve some degree of discomfort and/or pain. Pain control during orthodontic therapy is of great concern to both orthodontists and patients. However, there has been limited research into controlling such pain. The purpose of this work was to assess patient-perceived pain following fixed orthodontic treatment and to evaluate the comparative analgesic efficacy of non-steroidal anti-inflammatory drugs for controlling pain. A total of 45 patients about to undergo fixed appliance orthodontic treatment were enrolled in this double-blind prospective study. Patients were evenly and randomly distributed in a blinded manner to one of three groups as follows: paracetamol/acetaminophen 500 mg thrice daily; placebo in the form of empty capsules; and etoricoxib 60 mg once daily. Drug administration began 1 h before initiating the bonding procedure and archwire placement, and given until the day 3. The pain perceived was recorded by the patients on a linear and graded Visual Analogue Scale at time intervals of 2 h after insertion of the appliance; 6 h thereafter and again at nighttime of the same day of the appointment; 24 h later and on the 2nd day at nighttime; 48 h after the appointment and on day 3 at nighttime. Our results revealed that moderately intense pain is associated with routine orthodontic treatment, and that the amount of pain individuals perceive varies widely. We observed statistically significant differences in the pain control among the three groups, and that etoricoxib 60 mg proved most efficient. Etoricoxib 60 mg is highly efficacious for controlling pain during fixed orthodontic appliance therapy.

    Full Text Available Chronic inflammation has been linked to cancers, and use of non-steroidal anti-inflammatory drugs (NSAIDs has been associated with reduced risk of several cancers. To further refine the magnitude of NSAID-related associations, in particular for cancers related to inflammation, such as alcohol-, infection-, obesity-, and smoking-related cancers, as well as for less common cancers, we evaluated the use of NSAIDs and cancer risk in a very large cohort. We used propensity scores to account for potential selection bias and hypothesized that NSAID use is associated with decreased cancer incidence.We conducted a prospective study among 314,522 participants in the NIH-AARP Diet and Health Study. Individuals who completed the lifestyle questionnaire, which included NSAID use, in 1996-1997 were followed through 2006. Information on cancer incidence was ascertained by linking to cancer registries and vital status databases.During 2,715,994 person-years of follow-up (median 10.1 person-years, there were 51,894 incident cancers. Compared with non-users of NSAIDs, individuals who reported use in the 12 months prior to interview had a significantly lower risk of all inflammation-related cancer, alcohol-related, infection-related, obesity-related, and smoking-related cancers [hazard ratio (HR (95% CI 0.90 (0.87-0.93, 0.80 (0.74-0.85, 0.82 (0.78-0.87, 0.88 (0.84-0.92, and 0.88 (0.85-0.92 respectively].After accounting for potential selection bias, our data showed an inverse association between NSAID use and alcohol-related, infection-related, obesity-related, and smoking-related cancers and support the hypothesis that inflammation is related to an increased risk of certain cancers.

    Recent studies showed that the metal-coordinated non-steroidal anti-inflammatory drug (NSAID), copper indomethacin, reduced aberrant crypt formation in the rodent colon cancer model, while also exhibiting gastrointestinal sparing properties. In the present study, the stability and biological activity of three BiNSAIDs of the general formula [Bi(L)3]n, where L=diflunisal (difl), mefenamate (mef) or tolfenamate (tolf) were examined. NMR spectroscopy of high concentrations of BiNSAIDs (24h in cell medium, 37°C) indicated that their structural stability and interactions with cell medium components were NSAID specific. Assessment of cell viability using the [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium]bromide (MTT) assay showed that the toxicity ranking of the BiNSAIDs paralleled those of the respective free NSAIDs: diflHbismuth content was observed following treatment with [Bi(tolf)3]. Since NMR studies indicated that [Bi(tolf)3] was the most stable BiNSAID and that cellular uptake of bismuth correlated with structural stability it appears that bismuth uptake is assisted by the NSAID. Microprobe SR-XRF imaging showed that the intracellular fate of bismuth was independent of the specific BiNSAID treatment whereby all BiNSAID-treated cells showed bismuth accumulation in the cytoplasm within 24-h exposure. The size and location of the hot spots (0.3-5.8μm(2)), were consistent with cellular organelles such as lysosomes. Copyright © 2014 Elsevier Inc. All rights reserved.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are an effective and common treatment for chronic pain disorders, but long-term use is associated with risk of potentially life-threatening gastrointestinal adverse events (AEs). The proton pump inhibitor esomeprazole has been found to be effective for gastroprotection in NSAID users, but few long-term studies have been conducted in Japan. This was an open-label, multicentre, single-arm, prospective 1-year study of treatment with esomeprazole (20 mg once daily) in Japanese patients (aged ≥20 years) with endoscopic evidence of previous peptic ulcer and receiving daily oral NSAID therapy (at a stable dose) for a chronic condition. Eligibility was not dictated by type of oral NSAID. The primary objective was to determine long-term safety and tolerability of esomeprazole. Efficacy for prevention of peptic ulcers was also determined (Kaplan-Meier method). All statistical analyses were descriptive. A total of 130 patients (73.1% women, mean age 62.1 years, 43.8% Helicobacter pylori-positive) received treatment with esomeprazole in addition to long-term NSAID therapy (most commonly for rheumatoid arthritis [n=42] and osteoarthritis [n=34]). Loxoprofen, meloxicam and diclofenac were the most commonly used NSAIDs; cyclo-oxygenase (COX)-2 selective agents were used by 16.2% of patients (n=21). Long-term compliance with esomeprazole (capsule counts) was >75% for the majority of patients. Although 16.9% of patients (n=22) experienced AEs judged to be possibly related to treatment with esomeprazole, they were mostly mild and transient. The most commonly reported possibly treatment-related AEs were abnormal hepatic function, headache, increased γ-glutamyltransferase levels and muscle spasms (2 patients each). Overall, 95.9% (95% confidence interval: 92.3, 99.4) of patients remained ulcer free at 1 year. Long-term treatment with esomeprazole (20 mg once daily) is well tolerated and efficacious for preventing ulcer recurrence in

    A histamine-2 receptor antagonist (H2RA) is one of the common gastroprotective co-therapies used with non-steroidal anti-inflammatory drugs (NSAIDs) for the prevention or treatment of peptic ulcers (PUs). To date, no study has directly compared the prophylactic effectiveness between high-dose and low-dose H2RA. Our objective was to compare the effectiveness of high-dose versus low-dose H2RAs in the primary prophylaxis of PUs among short-term NSAID users. A retrospective cohort study was conducted using the Clinical Data Analysis and Reporting System (CDARS) in Hong Kong. Patients aged 18 years or above who received a single prescription of oral NSAID with oral H2RA were identified within the study period (1 January 2009-31 December 2012). Patients with a history of or risk factors for PU in the corresponding 2 years prior to the index date (of the first NSAID prescription) were excluded. Log binomial regression analysis was used to calculate the relative risk of PU among NSAID users with high-dose H2RA versus low-dose H2RA exposure. Among the NSAID cohort (n = 102,042), 77,509 (76 %) were on low-dose H2RA and 24,533 (24 %) were on high-dose H2RA. Of the total 69 PU cases identified during the drug exposure period, 64 (0.08 %) received low-dose-H2RA and five (0.02 %) received high-dose H2RA. The overall absolute risk of PUs for NSAID users whilst on H2RA was approximately 1 per 1,479 patients. The adjusted relative risk for NSAID users receiving high-dose H2RA versus low-dose H2RA was 0.32 (95 % confidence interval [CI] 0.13-0.79). Patients aged ≥65 years, receiving a longer duration of treatment, or with concomitant use of antiplatelet agents were found to be at higher risk of PU. High-dose H2RA showed greater effectiveness than low-dose H2RA in the primary prophylaxis of NSAID-associated PUs in short-term new users.

    In a Columbia, South Carolina-based case-control study, we developed a healthy lifestyle index from five modifiable lifestyle factors (smoking, alcohol intake, physical activity, diet, and body mass index), and examined the association between this lifestyle index and the risk of colorectal adenomatous polyps (adenoma). Participants were recruited from a local endoscopy center and completed questionnaires related to lifestyle behaviors prior to colonoscopy. We scored responses on each of five lifestyle factors as unhealthy (0 point) or healthy (1 point) based on current evidence and recommendations. We added the five scores to produce a combined lifestyle index for each participant ranging from 0 (least healthy) to 5 (healthiest), which was dichotomized into unhealthy (0-2) and healthy (3-5) lifestyle scores. We used logistic regression to calculate odds ratios (OR) and 95% confidence intervals (CI) for adenoma with adjustment for multiple covariates. We identified 47 adenoma cases and 91 controls. In the main analyses, there was a statistically nonsignificant inverse association between the dichotomous (OR 0.54; 95% CI 0.22, 1.29) and continuous (OR 0.75; 95% CI 0.51, 1.10) lifestyle index and adenoma. Odds of adenoma were significantly modified by the use of non-steroidal anti-inflammatory drugs (NSAIDs) (p(interaction) = 0.04). For participants who reported no use of NSAIDs, those in the healthy lifestyle category had a 72% lower odds of adenoma as compared to those in the unhealthy category (OR 0.28; 95% CI 0.08, 0.98), whereas a one-unit increase in the index significantly reduced odds of adenoma by 53% (OR 0.47; 95% CI 0.26, 0.88). Although these findings should be interpreted cautiously given our small sample size, our results suggest that higher scores from this index are associated with reduced odds of adenomas, especially in non-users of NSAIDs. Lifestyle interventions are required to test this approach as a strategy to prevent colorectal adenomatous

    The best available evidence regarding non-steroidal anti-inflammatory drug (NSAID)-related gastrointestinal (GI) bleeding comes from randomized controlled trials including patients who use NSAIDs to manage chronic rheumatic diseases; however, patients with varying background profiles commonly take NSAIDs for many other reasons, often without prescription, and such usage has not been well studied. To define the characteristics of patients hospitalized for upper GI bleeding in clinical practice, we conducted a case-control study among patients with endoscopy-proven major upper GI bleeding due to gastroduodenal peptic lesions and control subjects. We used adjusted logistic regression models to estimate bleeding risks. Data analysis was performed using SPSS 22.0. Our analysis included 3785 cases and 6540 controls, including 1270 cases (33.55%) and 834 controls (12.75%) reporting recent use (NSAIDs including high-dose acetylsalicylic acid (ASA). NSAID use was associated with increased risk of upper GI bleeding, with an adjusted relative risk of 4.86 (95% CI, 4.32-5.46). Acute musculoskeletal pain (36.1%), chronic osteoarthritis (13.5%), and headache (13.6%) were the most common reasons for NSAID use. Among cases, only 17.31% took NSAIDs and 6.38% took high dose ASA due to chronic osteoarthritis. Demographic characteristics significantly differed between subjects with chronic vs. acute musculoskeletal pain. Proton pump inhibitor use was significantly higher in patients who used NSAIDs due to chronic osteoarthritis compared to patients with acute musculoskeletal pain. NSAID (65.15%) or high-dose ASA use (65.83%) preceding upper GI bleeding was most often short-term. In over half of cases (63.62%), the upper GI bleeding event was not preceded by dyspeptic warning symptoms. The majority of patients hospitalized due to NSAID-related upper GI bleeding reported short-term NSAID use for reasons other than chronic rheumatic disease. These findings suggest that current prevention

    We sought to assess the trend of non-steroidal anti-inflammatory drug (NSAID) use in primary health care institutions located in A'Seeb, a province in the capital city of Oman, Muscat. Additionally, we evaluated the relationship between a physician's years of experience and the number of prescription issued, as well as the presence of risk factors and side effects in the patients who received these prescriptions. A clinical audit was conducted in four primary health care centers in the Muscat region over a one-week period in April 2014. The target population included patients aged 18 years or over who attended one of the four health centers and were prescribed NSAIDs. Overall, 272 patients were recruited by systematic random sampling. The data were collected by two methods: direct face-to-face interviews and evaluations of the patient's electronic medical file. The prescribing doctors were blind to the audit. The collected information included patients demographics, past and current medical history of related comorbidities, NSAID type, dose, duration and indications for use, concomitant warfarin or/and aspirin prescriptions, and co-prescription of gastroprotective agents. In total, 15% of patients received an NSAID prescription: females were issued more prescriptions than males. The percentage of patients who received an NSAID prescription across the health centers ranged from 9% to 24%. The main reason for prescribing NSAIDs was musculoskeletal problems. The most frequently prescribed NSAID was ibuprofen. Sixteen percent of patients who received an NSAID prescription had a risk factor related to its use. The mean and median duration of the NSAID prescriptions of all types were 5.6 and 5.0 days, respectively. Physicians with a greater number of years experience prescribed more NSAIDs. Our study showed that the number of prescriptions of NSAIDs among various institutes varied, which could reflect the level of awareness concerning NSAID risks among the prescribing

    AIM: This study investigated the mechanisms of protection afforded by the proton pump inhibitor lansoprazole against gastric injury induced by different non-steroidal anti-inflammatory drugs (NSAIDs) in rats. METHODS: Male Sprague-Dawley rats were orally treated with indomethacin (100 µmol/kg), diclofenac (60 µmol/kg), piroxicam (150 µmol/kg) or ketoprofen (150 µmol/kg). Thirty minutes before NSAIDs, animals were orally treated with lansoprazole 18 or 90 µmol/kg. Four hours after the end of treatments, the following parameters were assessed: gastric mucosal PGE2, malondialdehyde (MDA), myeloperoxidase (MPO) or non-proteic sulfhydryl compounds (GSH) levels; reverse transcription-polymerase chain reaction (RT-PCR) of mucosal COX-2 mRNA; gastric acid secretion in pylorus-ligated animals; in vitro effects of lansoprazole (1-300 µmol/L) on the oxidation of low density lipoproteins (LDLs) induced by copper sulphate. RESULTS: All NSAIDs elicited mucosal necrotic lesions which were associated with neutrophil infiltration and reduction of PGE2 levels. Increments of MPO and MDA contents, as well as a decrease in GSH levels were detected in the gastric mucosa of indomethacin- or piroxicam-treated animals. Indomethacin enhanced mucosal cyclooxygenase-2 expression, while not affecting cyclooxygenase-1. At the oral dose of 18 µmol/kg lansoprazole partly counteracted diclofenac-induced mucosal damage, whereas at 90 µmol/kg it markedly prevented injuries evoked by all test NSAIDs. Lansoprazole at 90 µmol/kg reversed also the effects of NSAIDs on MPO, MDA and GSH mucosal contents, without interfering with the decrease in PGE2 levels or indomethacin-induced cyclooxygenase-2 expression. However, both lansoprazole doses markedly inhibited acid secretion in pylorus-ligated rats. Lansoprazole concentration-dependently reduced the oxidation of LDLs in vitro. CONCLUSION: These results suggest that, besides the inhibition of acid secretion, lansoprazole protection against NSAID

    Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used to treat pain, but have potential side effects in patients with cardiovascular disease (CVD). To determine trends in NSAIDs prescribing between 2002 and 2010 in patients with CVD, and ascertain whether prescribing patterns changed following publication of major national (the Medicines and Healthcare products Regulatory Agency (MHRA) and the National Institute for Health and Clinical Excellence (NICE)) guidance to GPs. This was an observational database study of adult patients in 11 practices (Staffordshire, England). NSAIDs were categorised into basic, COX-2 and topical. Study duration was divided on a quarterly basis from 2002-quarter-1 to 2010q4. CVD patients were identified using pre-defined Read Codes recorded in the two years prior to each quarter. Quarterly prevalence was determined. Times of significant changes in prescribing trends were determined using Joinpoint Regression, and compared to dates of the five major guidelines (in 2004q4, 2005q1, 2005q3, 2006q4, 2008q1). In CVD patients, the prescription of basic NSAIDs showed a decreasing trend throughout the study period, from 774 (95% CI, 691-863) per 10000 patients in 2002q1 to 245 (204-291) in 2010q4. COX-2 prescribing increased from 232/10000 (187-286) in 2002q1 to 403/10000 (348-464) in 2004q3. Prescribing then fell sharply to 102/10000 (76-134) in 2005q2 before stabilising around 55/10000. Topical NSAIDs prescribing showed a steady increase, starting at 115/10000 (108-123) in 2002q1 and ending at 270/10000 (258-281) in 2010q4. Similar trends were observed in patients without CVD, particularly a sharp drop in COX-2 prescribing also occurred from 2004q4 when initial MHRA guidance was issued. Despite guidelines and a trend toward decreased prescribing, the use of potentially harmful NSAIDs continued in CVD patients. The MHRA directives potentially might have affected patients without CVD who may have inappropriately restricted their use of

    Full Text Available Abstract Background Osteoarthritis is a common presentation in primary care, and non-selective non-steroidal anti-inflammatory drugs (sometimes also referred to as traditional NSAIDs or tNSAIDs and selective cyclo-oxygenase 2 inhibitors (COX-2 inhibitors are commonly used to treat it. The UK's National Institute for Health and Clinical Excellence (NICE recommends taking patient risk factors into account when selecting a tNSAID or a COX-2 inhibitor, but GPs have lacked practical guidance on assessing patient risk. Methods A multi-disciplinary group that included primary care professionals (PCPs developed an evidence-based consensus statement with an accompanying flowchart that aimed at providing concise and specific guidance on NSAID use in osteoarthritis treatment. An open invitation to meet and discuss the issue was made to relevant healthcare professionals in South Yorkshire. A round table meeting was held that used a modified nominal group technique, aimed at generating opinions and ideas from all stakeholders in the consensus process. A draft developed from this meeting went through successive revisions until a consensus was achieved. Results Four statements on the use of tNSAIDs and COX-2 inhibitors (and an attached category of evidence were agreed: 1 tNSAIDs are effective drugs in relieving pain and immobility associated with osteoarthritis. COX-2 inhibitors are equally effective; 2 tNSAIDs and COX-2 inhibitors vary in their potential gastrointestinal, liver, and cardio-renal toxicity. This risk varies between individual treatments within both groups and is increased with dose and duration of treatment; 3 COX-2 inhibitors are associated with a significantly lower gastrointestinal toxicity compared to tNSAIDs. Co-prescribing of aspirin reduces this advantage; 4 PPIs should always be considered with a tNSAID and with a COX-2 inhibitor in higher GI risk patients. An accompanying flowchart to guide management was also agreed. Conclusions

  20. Crystal structures of three classes of non-steroidal anti-inflammatory drugs in complex with aldo-keto reductase 1C3.

    Full Text Available Aldo-keto reductase 1C3 (AKR1C3 catalyses the NADPH dependent reduction of carbonyl groups in a number of important steroid and prostanoid molecules. The enzyme is also over-expressed in prostate and breast cancer and its expression is correlated with the aggressiveness of the disease. The steroid products of AKR1C3 catalysis are important in proliferative signalling of hormone-responsive cells, while the prostanoid products promote prostaglandin-dependent proliferative pathways. In these ways, AKR1C3 contributes to tumour development and maintenance, and suggest that inhibition of AKR1C3 activity is an attractive target for the development of new anti-cancer therapies. Non-steroidal anti-inflammatory drugs (NSAIDs are one well-known class of compounds that inhibits AKR1C3, yet crystal structures have only been determined for this enzyme with flufenamic acid, indomethacin, and closely related analogues bound. While the flufenamic acid and indomethacin structures have been used to design novel inhibitors, they provide only limited coverage of the NSAIDs that inhibit AKR1C3 and that may be used for the development of new AKR1C3 targeted drugs. To understand how other NSAIDs bind to AKR1C3, we have determined ten crystal structures of AKR1C3 complexes that cover three different classes of NSAID, N-phenylanthranilic acids (meclofenamic acid, mefenamic acid, arylpropionic acids (flurbiprofen, ibuprofen, naproxen, and indomethacin analogues (indomethacin, sulindac, zomepirac. The N-phenylanthranilic and arylpropionic acids bind to common sites including the enzyme catalytic centre and a constitutive active site pocket, with the arylpropionic acids probing the constitutive pocket more effectively. By contrast, indomethacin and the indomethacin analogues sulindac and zomepirac, display three distinctly different binding modes that explain their relative inhibition of the AKR1C family members. This new data from ten crystal structures greatly broadens

    A rapid and reliable LC-MS/MS method for the simultaneous confirmation of twelve non steroidal anti-inflammatory drugs (NSAIDs) in bovine milk was developed and fully validated in accordance with the European Commission Decision 2002/657/EC. The validation scheme was built in accordance with the MRLs or target analytical levels (EU-CRL recommended concentrations and detection capabilities) of the analytes, except for diclofenac for which the lower level of validation achieved was 0.5 μg kg(-1) whereas its MRL is 0.1 μg kg(-1). The NSAIDs investigated were as follows: phenylbutazone (PBZ), oxyphenylbutazone (OPB), naproxen (NP), mefenamic acid (MF), vedaprofen (VDP), flunixin (FLU), 5-hydroxyflunixin (FLU-OH), tolfenamic acid (TLF), meloxicam (MLX), diclofenac (DC), carprofen (CPF) and ketoprofen (KTP). Several extraction procedures had been investigated during the development phase. Finally, the best results were obtained with a procedure using only methanol as the extraction solvent, with an evaporation step included and no further purification. Chromatographic separation was achieved on a C18 analytical column and the run was split in 2 segments. Matrix effects were also investigated. Data acquisition implemented for the confirmatory purpose was performed by monitoring 2 MRM transitions per analyte under the negative electrospray mode. Mean relative recoveries ranged from 94.7% to 110.0%, with their coefficients of variation lying between 2.9% and 14.7%. Analytical limits expressed in terms of decision limits (CCα) were evaluated between 0.69 μg kg(-1) (FLU) and 27.54 μg kg(-1) (VDP) for non-MRL compounds, and at 0.10 (DC), 15.37 (MLX), 45.08 (FLU-OH), and 62.96 μg kg(-1) (TLF) for MRL compounds. The validation results proved that the method is suitable for the screening and confirmatory steps as implemented for the French monitoring plan for NSAID residue control in bovine milk.

    Regular users of aspirin may have reduced risk of breast cancer. Few studies have addressed whether risk reduction pertains to specific breast cancer subtypes defined jointly by hormone receptor (estrogen and progesterone receptor) and human epidermal growth factor receptor 2 (HER2) expression. This study assessed the prospective risk of breast cancer (overall and by subtype) according to use of aspirin and other non-steroidal anti-inflammatory medications (NSAIDs) in a cohort of female public school professionals in California. In 1995 - 1996, participants in the California Teachers Study completed a baseline questionnaire on family history of cancer and other conditions, use of NSAIDs, menstrual and reproductive history, self-reported weight and height, living environment, diet, alcohol use, and physical activity. In 2005-2006, 57,164 participants provided some updated information, including use of NSAIDs and 1457 of these participants developed invasive breast cancer before January 2013. Multivariable Cox proportional hazards regression models provided hazard rate ratios (HRR) for the association between NSAID use and risk of invasive breast cancer as well as hormone receptor- and HER2-defined subtypes. Developing breast cancer was associated inversely with taking three or more tablets of low-dose aspirin per week (23% of participants). Among women reporting this exposure, the HRR was 0.84 (95% confidence interval (CI) 0.72-0.98) compared to those not taking NSAIDs and this was particularly evident in women with the hormone receptor-positive/HER2-negative subtype (HRR = 0.80, 95% CI 0.66-0.96). Use of three or more tablets of "other" NSAIDs was marginally associated with lower risk of breast cancer (HRR = 0.79, 95% CI 0.62-1.00). Other associations with NSAIDs were generally null. Our observation of reduced risk of breast cancer, among participants who took three or more tablets of low-dose aspirin weekly, is consistent with other reports looking at

    Acute otitis media (AOM) is one of the most common childhood infectious diseases and a significant reason for antibiotic prescriptions in children worldwide. Pain from middle ear infection and pressure behind the eardrum is the key symptom of AOM. Ear pain is central to children's and parents' experience of the illness. Because antibiotics provide only marginal benefits, analgesic treatment including paracetamol (acetaminophen) and non-steroidal anti-inflammatory drugs (NSAIDs) is regarded as the cornerstone of AOM management in children. Our primary objective was to assess the effectiveness of paracetamol (acetaminophen) or NSAIDs, alone or combined, compared with placebo or no treatment in relieving pain in children with AOM. Our secondary objective was to assess the effectiveness of NSAIDs compared with paracetamol in children with AOM. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Issue 7, July 2016; MEDLINE (Ovid, from 1946 to August 2016), Embase (from 1947 to August 2016), CINAHL (from 1981 to August 2016), LILACS (from 1982 to August 2016) and Web of Science (from 1955 to August 2016) for published trials. We screened reference lists of included studies and relevant systematic reviews for additional trials. We searched WHO ICTRP, ClinicalTrials.gov, and the Netherlands Trial Registry (NTR) for completed and ongoing trials (search date 19 August 2016). We included randomised controlled trials (RCTs) comparing the effectiveness of paracetamol or NSAIDs, alone or combined, for pain relief in children with AOM. We also included trials of paracetamol or NSAIDs, alone or combined, for children with fever or upper respiratory tract infections (URTIs) if we were able to extract subgroup data on pain relief in children with AOM either directly or after obtaining additional data from study authors. Two review authors independently assessed methodological quality of the included trials and extracted data. We used the GRADE approach to rate

    Primary Care is the fundamental axis of our health system and obliges us to be consistent with our prescriptions. The non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with increased cardiovascular risk and increased risk of all causes of death, as well as acute myocardial infarction (AMI) in patients with a previous myocardial infarction. Pain and cardiac patient management are 2 basic pillars in our daily activity, and we must know the limitations of NSAIDs in patients with established cardiovascular risk. We present a review of the scientific literature with primary interest in the role of NSAIDs and cardiovascular risk. The objective is to determine the relationship between the consumption of different NSAIDs and the fatal and non-fatal events among patients with known coronary disease. This is a review of the scientific literature with primary interest in the role of NSAIDs and cardiovascular risk. The literature review was conducted in PubMed search engines like Tripdatabase and with certain keywords. Of the 15 original papers found, 9 did not correspond completely to the central focus, so the approach was decided from 6 original articles from the past 5 years, which address the central focus of increased cardiovascular risk found (fatal and non-fatal events) in patients with prior cardiovascular disease or AMI being prescribed NSAIDs for any reason. The risk of fatal/non-fatal events in each of the studies is expressed by the odds ratio (OR)/hazard ratio (HR), defined as the probability of an event occurring. A moderate risk was observed for ibuprofen. It increases the risk of acute coronary syndrome after 5 years of cardiovascular event, especially in the 2nd year (OR 1.63; 95% CI 1.42-1.87). It also increases the risk of stroke (HR 1.23; 95% IC 1.10-1.38). Cyclo-oxygenase-2 inhibitors were the third risk group, after nabumetone and diclofenac. Celecoxib increases risk from the 14th day of treatment (HR 2.3; 95% CI 1.79-3.02), having an OR

    Sulfur mustard (bis(2-chloroethyl) sulfide, SM) is a highly reactive bifunctional alkylating agent inducing edema, inflammation, and the formation of fluid-filled blisters in the skin. Medical countermeasures against SM-induced cutaneous injury have yet to be established. In the present studies, we tested a novel, bifunctional anti-inflammatory prodrug (NDH 4338) designed to target cyclooxygenase 2 (COX2), an enzyme that generates inflammatory eicosanoids, and acetylcholinesterase, an enzyme mediating activation of cholinergic inflammatory pathways in a model of SM-induced skin injury. Adult SKH-1 hairless male mice were exposed to SM using a dorsal skin vapor cup model. NDH 4338 was applied topically to the skin 24, 48, and 72 h post-SM exposure. After 96 h, SM was found to induce skin injury characterized by edema, epidermal hyperplasia, loss of the differentiation marker, keratin 10 (K10), upregulation of the skin wound marker keratin 6 (K6), disruption of the basement membrane anchoring protein laminin 322, and increased expression of epidermal COX2. NDH 4338 post-treatment reduced SM-induced dermal edema and enhanced skin re-epithelialization. This was associated with a reduction in COX2 expression, increased K10 expression in the suprabasal epidermis, and reduced expression of K6. NDH 4338 also restored basement membrane integrity, as evidenced by continuous expression of laminin 332 at the dermal–epidermal junction. Taken together, these data indicate that a bifunctional anti-inflammatory prodrug stimulates repair of SM induced skin injury and may be useful as a medical countermeasure. - Highlights: • Bifunctional anti-inflammatory prodrug (NDH4338) tested on SM exposed mouse skin • The prodrug NDH4338 was designed to target COX2 and acetylcholinesterase. • The application of NDH4338 improved cutaneous wound repair after SM induced injury. • NDH4338 treatment demonstrated a reduction in COX2 expression on SM injured skin. • Changes of skin repair

    Traditional nonsteroidal anti-inflammatory drugs, tNSAIDs, are effective medication for prevention of ischemic events and treatment of pain, fever and inflammation. However their use associates with a significant risk to develop gastrointestinal and cardiovascular complications. Low doses of acetyl salicylic acid (ASA) and effective doses of tNSAIDs associate with a 2-6 fold increase in the risk of gastrointestinal bleeding. ASA and tNSAIDs inhibit cyclooxygenases (COXs). The COX exists at least in two isoforms, COX-1 and COX-2. Selective inhibitors of COX-2, the coxibs, spares the gastrointestinal tract while exert anti-inflammatory and analgesic effects. However, coxibs increase the risk of thrombo-embolic events. Nitric oxide (NO) and hydrogen sulfide (H₂S), are potent vasodilatory agents that maintain mucosal integrity in the gastrointestinal tract. Hybrid molecules generated by coupling a NO or H₂S releasing moiety to ASA or tNSAIDs has resulted into new classes of NSAIDs. These agents, the NO-releasing NSAIDs, or CINOD, and the H₂S releasing NSAIDs are currently investigated as a potential alternative to tNSAIDs and coxibs. Naproxcinod has been the first, and so far the only, CINOD investigated in clinical trials. These studies have shown a slightly improvement in gastrointestinal tolerability in comparison to naproxen in surrogate endpoints (number of gastric and duodenal ulcers) and a significant reduction in the risk of destabilization of blood pressure control in patients with osteoarthosis taking anti-hypertensive medications in comparison to either naproxen and rofecoxib. The lack of outcome studies, however, has precluded the approval of naproxcinod by the Food and Drug Administration leading to a voluntary withdrawn of an application to the EMEA in May 2011. NSAIDs that releases H₂S as a mechanism supporting an intrinsic gastrointestinal and cardiovascular safety are being investigated in preclinical models. Either naproxen and diclofenac

    Nonsteroidal anti-inflammatory drugs (NSAIDs) and aspirin are widely used clinically but increase the risk of gastrointestinal (GI) complications. To examine the current prescription of NSAIDs and comedication to prevent GI complications from NSAIDs within East Asia by means of a questionnaire survey. Representative members of the Committee of the International Gastrointestinal Consensus Symposium provided a questionnaire to physicians in 6 East Asian countries. A total of 1,568 physicians participated in this survey. Most physicians prescribed nonselective NSAIDs, cyclooxygenase-2 inhibitors (COXIBs) or aspirin for more than 5 patients per week in all countries, with the exception of the prescription of COXIBs in Japan. Of the nonselective NSAIDs, the drug most frequently prescribed as a first choice was loxoprofen (34%), which was mainly prescribed in Japan, followed by diclofenac (30%). The frequency of prescription of comedication with nonselective NSAIDs was higher compared with that for selective COXIBs or aspirin. Physicians in the northern region (China, Japan and Korea) preferred mucoprotective drugs for comedication with NSAIDs or aspirin, while those in southern region (Indonesia, Philippines and Thailand) frequently used proton-pump inhibitors. Among East Asian countries, there are both similarities and differences in the prescription of NSAIDs and of comedication to prevent GI complications.

    The permanent world-wide increase in therapeutic administration of racemic profens as easy available non-prescribed analgesic drugs and a common first-choice anti-inflammatory agents was recently linked with renewed interest in their beneficial use, also as enantiopure formulations, to treat and/or prevent a variety of human malignancies including its four major types as colorectal, breast, lung, and prostate cancer. This underlies the continuous need of selecting perfectly suited chiral separation methods of profens capable to determine nanolevels of a distomer in presence of the eutomer in a variety of complex biological and environmental media. Thus, current improvements for direct enantiomeric separations of profens by well defined supramolecular-based chiral HPLC and recently developed monolithic, combinatorial, bimodal and polymeric chiral stationary phases employing a modern supramolecular chirality concepts has been outlined in this review. The use of diverse supramolecular approaches for chiral HPLC as an easy accessible tool enabling fast development of nanoscale enantioselective, high-throughput and gradient screening procedures for in situ monitoring of stereoselective ADME properties of profens in range of anticancer drug discovery technologies has been also addressed.

    Magnetic core-shell nanoparticles (mag-NPs) of type SiO 2 -Fe 3 O 4 were covalently modified with the ionic liquid dimethyl octadecyl[3-(trimethoxysilyl propyl)]ammonium chloride. The NPs were characterized via FTIR and scanning electron microscopy and evaluated with respect to the extraction of the nonsteroidal anti-inflammatory drugs (NSAIDs) tolmetin, indometacin and naproxen from blood samples. Supercritical fluid extraction was used to eliminate matrix effects before extraction with the mag-NPs. The effects of pH value of sample solution, amount of adsorbent, times of adsorption and desorption, salt effect, type and volume of suitable solvent for desorption were optimized. Under optimum conditions, magnetic solid phase extraction (MSPE) resulted in limits of detection that range between 0.1 and 0.3 μg L −1 . In case of supercritical fluid extraction along with magnetic solid phase extraction (SFE- MSPE), the LODs ranged from 0.2 to 0.3 mg kg −1 . The analytical ranges for all of the NSAIDs varied within 0.2–15 mg kg -1 and 0.1–250 μg L −1 in the SFE-MSPE and MSPE methods, respectively. The relative standard deviations for the extraction of the NSAIDs from blood samples via SFE-MSPE are <10.2%. (author)

  11. Aging Enables Ca2+ Overload and Apoptosis Induced by Amyloid-β Oligomers in Rat Hippocampal Neurons: Neuroprotection by Non-Steroidal Anti-Inflammatory Drugs and R-Flurbiprofen in Aging Neurons.

    The most important risk factor for Alzheimer's disease (AD) is aging. Neurotoxicity in AD has been linked to dyshomeostasis of intracellular Ca2+ induced by small aggregates of the amyloid-β peptide 1-42 (Aβ42 oligomers). However, how aging influences susceptibility to neurotoxicity induced by Aβ42 oligomers is unknown. In this study, we used long-term cultures of rat hippocampal neurons, a model of neuronal in vitro aging, to investigate the contribution of aging to Ca2+ dishomeostasis and neuron cell death induced by Aβ42 oligomers. In addition, we tested whether non-steroidal anti-inflammatory drugs (NSAIDs) and R-flurbiprofen prevent apoptosis acting on subcellular Ca2+ in aged neurons. We found that Aβ42 oligomers have no effect on young hippocampal neurons cultured for 2 days in vitro (2 DIV). However, they promoted apoptosis modestly in mature neurons (8 DIV) and these effects increased dramatically after 13 DIV, when neurons display many hallmarks of in vivo aging. Consistently, cytosolic and mitochondrial Ca2+ responses induced by Aβ42 oligomers increased dramatically with culture age. At low concentrations, NSAIDs and the enantiomer R-flurbiprofen lacking anti-inflammatory activity prevent Ca2+ overload and neuron cell death induced by Aβ42 oligomers in aged neurons. However, at high concentrations R-flurbiprofen induces apoptosis. Thus, Aβ42 oligomers promote Ca2+ overload and neuron cell death only in aged rat hippocampal neurons. These effects are prevented by low concentrations of NSAIDs and R-flurbiprofen acting on mitochondrial Ca2+ overload.

    It has been suggested that the risk of acute kidney injury (AKI) increases with the number of drugs associated between non-steroidal anti-inflammatory drugs (NSAIDs), angiotensin converting enzyme inhibitors (ACEis) [or angiotensin receptor blockers (ARBs)] and diuretics. We aimed to investigate whether the number of drugs associated between NSAIDs, ACEis, ARBs and diuretics was associated to disproportionate reporting of AKI in the French Pharmacovigilance Database. In reports of Adverse Drug Reactions (ADRs) recorded between 01 January 2008 and 31 December 2010, we selected patients whose medications included at least one oral antihypertensive drug. We used a case/non-case methodology. Cases were AKI and non-cases were all the remaining reports. Among the 11,442 ADR reports in patients under antihypertensive drug recorded in the French Pharmacovigilance Database, 837 ADRs were AKI (7.3%, 95% CI 6.8-7.8). AKI and the number of drugs associated were disproportionately reported (one drug alone: adjusted ROR 2.19, 95% CI: 1.65-2.89, two drugs: adjusted ROR 5.27, 95% CI: 4.00-6.94, three and more: adjusted ROR 16.46, 95% CI: 11.38-23.80). There was no significant association between NSAIDs' half-lives and reporting of AKI (adjusted ROR=0.54, 95% CI: 0.25-1.15). Given the widespread use of these hazardous drugs in general population, caution is needed when they are associated.

    To investigate the feasibility and sample size required for a full-scale randomised controlled trial of the effectiveness of acupuncture with non-steroidal anti-inflammatory drugs (NSAIDs) for chronic neck pain compared with acupuncture or NSAID treatment alone. A total of 45 patients with chronic neck pain participated in the study. For 3 weeks the acupuncture with NSAIDs treatment group took NSAIDs (zaltoprofen, 80 mg) daily while receiving acupuncture treatment three times a week. The acupuncture treatment group received treatment three times a week and the NSAID treatment group took NSAIDs daily. The primary outcomes were to determine the feasibility and to calculate the sample size. As secondary outcomes, pain intensity and pain-related symptoms for chronic neck pain were measured. With regard to enrolment and dropout rates, 88.2% of patients consented to be recruited to the trial and 15.6% of participants were lost to follow-up. The sample size for a full-scale trial was estimated to be 120 patients. Although preliminary, there was a significant change in the visual analogue scale (VAS) for neck pain intensity between the baseline measurement and each point of assessment in all groups. However, there was no difference in VAS scores between the three groups. This pilot study has provided the feasibility and sample size for a full-scale trial of acupuncture with NSAIDs for chronic neck pain compared with acupuncture or NSAID treatment alone. Further research is needed to validate the effects of acupuncture with NSAIDs.

    The ability to induce changes in cell membrane properties is nowadays considered an additional mechanism to explain the pharmacological effects of non-steroidal anti-inflammatory drugs (NSAIDs). We previously demonstrated that the NSAID Licofelone, a dual cyclooxygenase/5-lipoxygenase inhibitor, triggers apoptosis in HCA-7 colon cancer cells independently from the inhibition of these enzymes. Here, we provide evidence that, in HCA-7 cells, the pro-apoptotic effect of this drug relies, at least in part, on its ability to inhibit epidermal growth factor receptor (EGFR) signalling by a decrease of cell membrane fluidity. Indeed, Licofelone induced a relevant change in the relative proportions of some saturated, monounsaturated and polyunsaturated fatty acids constituting HCA-7 phospholipid fraction and significantly increased the levels of cholesterol in HCA-7 cell membrane. All of these changes resulted in a remarkable decrease of membrane fluidity. Such phenomenon was associated with the block of EGFR kinase activity and of its downstream targets, the p44-42 mitogen-activated protein kinase (MAPK) and AKT cascades, whose inhibitions were found to induce apoptosis in HCA-7 cells. Overall, these findings provide a new additional mechanism by which NSAIDs are effective toward colon cancer cells. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Disease-modifying anti-rheumatic drugs (DMARDs and biological drugs can interfere with the disease process. In this study, the effect of β-D-mannuronic acid (M2000 as a novel non-steroidal anti-inflammatory drug (NSAID with immunosuppressive and anti-inflammatory effects together with antioxidant effects was evaluated on IL17, RORγt, IL4 and GATA3 gene expression in 12 RA patients. Previously, M2000 driven from sodium alginate (natural product; patented, DEU: 102016113018.4 has shown a notable efficacy in experimental models of multiple sclerosis, RA and nephrotic syndrome. This study was performed on 12 patients with RA who had an inadequate response to conventional treatments. During this trial, patients were permitted to continue the conventional therapy excluding NSAIDs. M2000 was administered orally at a dose of 500 mg twice daily for 12 weeks. The peripheral blood mononuclear cells (PBMCs were collected before and after treatment to evaluate the expression levels of IL4, GATA3, IL17 and RORγt. The gene expression results showed that M2000 has a potent efficacy, so that it could not only significantly decrease IL17 and RORγt levels but also increase IL4 and GATA3 levels after 12 weeks of treatment. Moreover, the gene expression results were in accordance with the clinical and preclinical assessments. In conclusion, M2000 as a natural novel agent has therapeutic and immunosuppressive properties on RA patients (identifier

    Helicobacter pylori-negative and non-steroidal anti-inflammatory drugs (NSAIDs)-negative idiopathic peptic ulcers (IPU) have attracted attention in Japan and other developed countries. The aim of the present study was to clarify the healing rate of IPU and the risk of recurrence. We conducted a retrospective follow-up study of patients with peptic ulcer disease (PUD) who were diagnosed in our previous multicenter-prospective study. Three hundred and eighty-two patients from four institutions in the Tohoku district were enrolled. Enrolled subjects were divided into four groups according to H. pylori infection and intake of NSAIDs. In these patients, we checked treatment course, healing rate during 3 months, and recurrence rate. Healing rates in the: (i) simple H. pylori group; (ii) H. pylori (+)/ NSAIDs (+) group, (iii) simple NSAIDs group; and (iv) IPU group, were 95.0%, 94.9%, 73.3%, and 77.4%, respectively. The healing rate of the IPU group was significantly lower than that of both the simple H. pylori group and the H. pylori (+)/ NSAIDs (+) group (P < 0.01). The recurrence rate of 13.9% in the IPU group was much higher than the 2.1% in the simple H. pylori group (P < 0.01). Additionally, the cumulative recurrence rates by the Kaplan-Meier method in the IPU group were significantly higher than those of the simple H. pylori group (P = 0.015). We demonstrated that the clinical course of peptic ulcers is considerably different depending on the cause. IPU could be refractory to treatment and prone to recur compared with simple H. pylori ulcers. © 2016 Japan Gastroenterological Endoscopy Society.

    Summary: In this study, simple and efficient ultrasound-assisted dispersive liquid-liquid micro extraction combined with gas chromatography (GC) was developed for the preconcentration and determination of benzaldehyde in injectable formulations of the non-steroidal anti-inflammatory drugs, diclofenac, Vitamin B-complex and Voltaren injection solutions. Fourteen microliters of toluene was injected slowly into 10 mL home-designed centrifuge glass vial containing an aqueous sample without salt addition that was located inside the ultrasonic water bath. The formed emulsion was centrifuged and 2 macro L of separated toluene was injected into a gas chromatographic system equipped with a flame ionization detector (GC-FID) for analysis. Several factors influencing the extraction efficiency as the nature and volume of organic solvent, extraction temperature, ionic strength and centrifugation time were investigated and optimized. Using optimum extraction conditions a detection limit of 0.3 macro g L/sup -1/ and a good linearity in a calibration range of 2.0-1000 macro g L/sup -1/ were achieved for analyte. This proposed method was successfully applied to the analysis of benzaldehyde in three injection formulations and relative standard deviation (RSD) of analysis (n=3), before spiking with standard benzaldehyde were 3.3, 2.0 and 1.3% for Na-diclofenac, vitamin B-complex and voltaren, respectively and after spiking of standard benzaldehyde (0.3 mg L/sup -1/), the RSD were 6.5, 3.6 and 2.8% for Na-diclofenac, vitamin B-complex and voltaren, respectively.

    Non-steroidal anti-inflammatory drugs (NSAIDs) may be prothrombotic, may worsen hypertension or congestive heart failure and obstruct access to the binding site of aspirin to cyclooxygenase-1 and thereby interfere with aspirin's mechanism of action in reducing death and recurrent myocardial infarction (MI). We hypothesized that treatment with NSAIDs prior to an index MI would be associated with an increase in the risk of death, heart failure and recurrent MI among patients with ST-segment elevation MI (STEMI) treated with fibrinolytic therapy. In ExTRACT-TIMI 25, patients with STEMI were treated with aspirin and fibrinolytic therapy and randomized to either enoxaparin or unfractionated heparin. We included patients who had received NSAIDs within 7 days of enrollment and evaluated the incidence of MI, the composite of death and MI and the composite of death, MI, severe heart failure and shock through 30 days. Of 20,479 patients enrolled, 572 (2.8%) received an NSAID within 7 days of enrollment. NSAID treatment prior to entry was associated with a higher incidence of 30-day death or nonfatal recurrent MI (15.9% vs. 10.8%, univariate P NSAID use was associated with higher odds of MI (adjusted odds ratio [OR(adj)] 1.44, 95% confidence interval [CI] 1.01-2.07, P = 0.047), the composite of death and MI (OR(adj) 1.29, 95% CI 1.00-1.66, P = 0.051), and the composite of death, MI, severe heart failure and shock (OR(adj) 1.29, 95% CI 1.02-1.65, P = 0.037). Among STEMI patients treated with a fibrinolytic agent and aspirin, use of NSAIDs in the week preceding the incident event was associated with a higher incidence of MI, the composite of death and MI as well as the composite of death, MI, severe heart failure and shock at 30 days.

    Non-steroidal anti-inflammatory drugs (NSAIDs) have been suggested as the potential new class of preventive or therapeutic antitumor agents. The aim of the present study was to evaluate the antitumor activity of the novel NSAID, CG100649. CG100649 is a novel NSAID dual inhibitor for COX-2 and carbonic anhydrase (CA)-I/-II. In the present study, we investigated the alternative mechanism by which CG100649 mediated suppression of the colon cancer growth and development. The anchorage‑dependent and -independent clonogenic assay showed that CG100649 inhibited the clonogenicity of human colon cancer cells. The flow cytometric analysis showed that CG100649 induced the G2/M cell cycle arrest in colon cancer cells. Animal studies showed that CG100649 inhibited the tumor growth in colon cancer xenograft in nude mice. Furthermore, quantitative PCR and FACS analysis demonstrated that CG100649 upregulated the expression of TNF-related apoptosis-inducing ligand (TRAIL) receptors (DR4 and DR5) but decreased the expression of decoy receptors (DcR1 and DcR2) in colon cancer cells. The results showed that CG100649 treatment sensitized TRAIL‑mediated growth suppression and apoptotic cell death. The combination treatment resulted in significant repression of the intestinal polyp formation in APCmin/+ mice. Our data clearly demonstrated that CG100649 contains preventive and therapeutic activity for colon cancer. The present study may be useful for identification of the potential benefit of the NSAID CG100649, for the achievement of a better treatment response in colon cancer.

    A number of clinical studies have shown that non-steroidal anti-inflammatory drugs (NSAIDs) exacerbate inflammatory bowel disease; however the molecular mechanism whereby this occurs remains unclear. NSAIDs inhibit cyclooxygenase (COX), which has subtypes COX-1 and COX-2. In this study, we have examined the effect of various types of NSAIDs on the development of dextran sulfate sodium (DSS)-induced colitis, an animal model of inflammatory bowel disease. The DSS-induced colitis was worsened by administration of non-selective NSAIDs but not by COX-1 or COX-2 selective inhibitors. However, administration of a combination of both COX-1- and COX-2-selective inhibitors exacerbated the colitis. The intestinal level of PGE(2) dramatically decreased in response to administration of COX-1- and COX-2-selective inhibitors, and exogenously administered PGE(2) suppressed the exacerbation of colitis by NSAIDs. The expression of mucin proteins, which protect the intestinal mucosa, was suppressed by non-selective NSAIDs and this expression was restored by PGE(2), both in vivo and in vitro. Intestinal mucosal cell growth was inhibited by non-selective NSAIDs and this cell growth was restored by PGE(2), both in vivo and in vitro. This study provides evidence that inhibition of both COX-1 and COX-2 and the resulting dramatic decrease in the intestinal level of PGE(2) is responsible for NSAID-dependent exacerbation of DSS-induced colitis. Furthermore, expression of mucin proteins and intestinal mucosal cell growth seems to be involved in this exacerbation and its suppression by PGE(2).

    Objective The etiology of prostate cancer (PCa) is still unclear. This study aimed to investigate the association between PCa risk and the indicators of endogenous androgen production at puberty, male pattern baldness, over-the-counter use of non-steroidal anti-inflammatory drugs and vitamin supplement use. Materials and methods Participants in the third round of the Finnish Prostate Cancer Screening Trial were sent a survey on possible PCa risk factors and 11,795 out of 12,740 (93%) men returned the questionnaire. PCa cases were identified from the Finnish Cancer Registry. Results During the median follow-up of 6.6 years, 757 PCa cases were diagnosed and 21 men died from PCa. Compared to earlier onset, puberty onset after 15 years of age was associated with a borderline significant decrease in PCa risk [hazard ratio (HR) 0.87, 95% confidence interval (CI) 0.75-1.00] but not with PCa mortality. Weekly use of ibuprofen was associated with an increased risk of PCa overall (HR 1.43, 95% CI 1.08-1.91) and with metastatic PCa (HR 1.49, 95% CI 1.12-1.99) compared to less frequent use. No statistically significant association was found between vitamin use and PCa. Conclusions This study suggests that the timing of initiation of endogenous androgen production at puberty may have importance for later PCa development. Current use of over-the-counter ibuprofen is associated with an increased risk of PCa. There was no evidence of any protective effects of vitamin use on PCa risk.

    We tested a range of drugs for their effects on in vitro polyclonal IgG synthesis by human peripheral blood mononuclear cells (PBMC) stimulated with the lectin pokeweed mitogen (PWM). The test drugs were selected on the basis of reported disruptive effects on immune function in vivo. IgG production between day 4 and days 7 or 8 of culture was measured by biotin-streptavidin sandwich ELISA. The anti-psychotic agent chlorpromazine (0.55-1.7 microM) enhanced IgG synthesis to approximately double control levels. In contrast, the non-steroidal anti-inflammatory drugs (NSAIDs) indomethacin, piroxicam, ibuprofen and aspirin inhibited IgG synthesis by up to 50%, with a rank order of potency that reflects their activity as inhibitors of cyclo-oxygenase. Phenytoin, procainamide, propylthiouracil, methimazole, D-penicillamine and D-penicillamine-L-cysteine all failed to modulate IgG synthesis at non-toxic concentrations. The potentiation and inhibition of IgG synthesis by chlorpromazine and indomethacin, respectively, was observed only when the drug was present during the first 24 h of culture. Neither chlorpromazine nor indomethacin, at non-toxic concentrations, affected PHA- and PWM-stimulated proliferation of PBMC. In addition, chlorpromazine, indomethacin and piroxicam, at concentrations which produced maximal modulation of IgG synthesis, and D-penicillamine and D-penicillamine-L-cysteine at 10 microM failed to influence production of interleukin-1-like activity. We conclude that chlorpromazine and NSAIDs, although they exert opposite effects on IgG synthesis, act at an early stage of B cell differentiation that appears to be independent of interleukin 1 synthesis and early proliferative events.

    Low-dose lansoprazole has not been intensively evaluated for its efficacy in the prevention of recurrent gastric or duodenal ulcers in patients receiving long-term non-steroidal anti-inflammatory drug (NSAID) therapy for pain relief in such diseases as rheumatoid arthritis, osteoarthritis, and low back pain. This multi-center, prospective, double-blind, randomized, active-controlled study involving 99 sites in Japan was designed to compare the efficacy of lansoprazole (15 mg daily) with gefarnate (50 mg twice daily). Patients with a history of gastric or duodenal ulcers who required long-term NSAID therapy were randomized to receive lansoprazole 15 mg daily (n = 185) or gefarnate 50 mg twice daily (n = 181) and followed up for 12 months or longer prospectively. The cumulative incidence of gastric or duodenal ulcer at days 91, 181, and 361 from the start of the study was calculated by the Kaplan-Meier method as 3.3, 5.9, and 12.7%, respectively, in the lansoprazole group versus 18.7, 28.5, and 36.9%, respectively, in the gefarnate group. The risk for ulcer development was significantly (log-rank test, P lansoprazole group than in the gefarnate group, with the hazard ratio being 0.2510 (95% CI 0.1400-0.4499). A long-term follow-up study showed an acceptable safety profile for low-dose lansoprazole therapy, with diarrhea as the most frequent adverse event. Lansoprazole was superior to gefarnate in reducing the risk of gastric or duodenal ulcer recurrence in patients with a definite history of gastric or duodenal ulcers who required long-term NSAID therapy.

    A systematic review on the cost effectiveness of prophylactic treatments of non-steroidal anti-inflammatory drug (NSAID) induced gastropathy in patients with osteoarthritis or rheumatoid arthritis was conducted. Two reviewers conducted the literature search and the review. Both full and partial economic evaluations published in English, Dutch, or German were included. The criteria list published in the textbook of Drummond was used to determine the quality of the economic evaluations. The methodological quality of three randomised controlled trials (RCTs) in which the economic evaluations obtained probability estimates of NSAID induced gastropathy and adverse events was assessed by a list of internal validity criteria. The conclusions were based on a rating system consisting of four levels of evidence.
  Ten economic evaluations were included; three were based on RCTs. All evaluations studied misoprostol as prophylactic treatment: in one evaluation misoprostol was studied as a fixed component in a combination with diclofenac (Arthrotec). All economic evaluations comprised analytical studies containing a decision tree. The three trials were of high methodological quality. Nine economic evaluations were considered high quality and one economic evaluation was considered of low methodological quality. There is strong evidence (level "A") that the use of misoprostol for the prevention of NSAID induced gastropathy is cost effective, and limited evidence (level "C") that the use of Arthrotec is cost effective. Although the levels of evidence used in this review are arbitrary, it is believed that a qualitative analysis is useful: quantitative analyses in this field are hampered by the heterogeneity of economic evaluations. Existing criteria to evaluate the methodological quality of economic evaluations may need refinement for use in systematic reviews.

    Full Text Available BACKGROUND: Certain non-steroidal anti-inflammatory drugs (NSAIDs (e.g., rofecoxib [Vioxx] increase the risk of heart attack and stroke and should be avoided in patients at high risk of cardiovascular events. Rates of cardiovascular disease are high and rising in many low- and middle-income countries. We studied the extent to which evidence on cardiovascular risk with NSAIDs has translated into guidance and sales in 15 countries. METHODS AND FINDINGS: Data on the relative risk (RR of cardiovascular events with individual NSAIDs were derived from meta-analyses of randomised trials and controlled observational studies. Listing of individual NSAIDs on Essential Medicines Lists (EMLs was obtained from the World Health Organization. NSAID sales or prescription data for 15 low-, middle-, and high-income countries were obtained from Intercontinental Medical Statistics Health (IMS Health or national prescription pricing audit (in the case of England and Canada. Three drugs (rofecoxib, diclofenac, etoricoxib ranked consistently highest in terms of cardiovascular risk compared with nonuse. Naproxen was associated with a low risk. Diclofenac was listed on 74 national EMLs, naproxen on just 27. Rofecoxib use was not documented in any country. Diclofenac and etoricoxib accounted for one-third of total NSAID usage across the 15 countries (median 33.2%, range 14.7-58.7%. This proportion did not vary between low- and high-income countries. Diclofenac was by far the most commonly used NSAID, with a market share close to that of the next three most popular drugs combined. Naproxen had an average market share of less than 10%. CONCLUSIONS: Listing of NSAIDs on national EMLs should take account of cardiovascular risk, with preference given to low risk drugs. Diclofenac has a risk very similar to rofecoxib, which was withdrawn from worldwide markets owing to cardiovascular toxicity. Diclofenac should be removed from EMLs.

    To assess whether a double therapy combination consisting of diuretics, angiotensin converting enzyme inhibitors, or angiotensin receptor blockers with addition of non-steroidal anti-inflammatory drugs (NSAIDs) and the triple therapy combination of two of the aforementioned antihypertensive drugs to which NSAIDs are added are associated with an increased risk of acute kidney injury. Retrospective cohort study using nested case-control analysis. General practices contributing data to the UK Clinical Practice Research Datalink linked to the Hospital Episodes Statistics database. A cohort of 487,372 users of antihypertensive drugs. Rate ratios with 95% confidence intervals of acute kidney injury associated with current use of double and triple therapy combinations of antihypertensive drugs with NSAIDs. During a mean follow-up of 5.9 (SD 3.4) years, 2215 cases of acute kidney injury were identified (incidence rate 7/10,000 person years). Overall, current use of a double therapy combination containing either diuretics or angiotensin converting enzyme inhibitors or angiotensin receptor blockers with NSAIDs was not associated with an increased rate of acute kidney injury. In contrast, current use of a triple therapy combination was associated with an increased rate of acute kidney injury (rate ratio 1.31, 95% confidence interval 1.12 to 1.53). In secondary analyses, the highest risk was observed in the first 30 days of use (rate ratio 1.82, 1.35 to 2.46). A triple therapy combination consisting of diuretics with angiotensin converting enzyme inhibitors or angiotensin receptor blockers and NSAIDs was associated with an increased risk of acute kidney injury. The risk was greatest at the start of treatment. Although antihypertensive drugs have cardiovascular benefits, vigilance may be warranted when they are used concurrently with NSAIDs.

    Full Text Available Abstract Background Minocycline and a non-steroidal anti-inflammatory drug (NSAID indomethacin, have anti-inflammatory activities and are both used in the management of rheumatoid arthritis. However, there are no reports on whether coadministration of these drugs could potentiate each other's activities in alleviating pain and weight bearing deficits during arthritis. Methods LPS was injected to BALB/c mice intraperitoneally (i.p. to induce thermal hyperalgesia. The hot plate test was used to study thermal nociception in naïve BALB/c and C57BL/6 mice and BALB/c mice with LPS-induced thermal hyperalgesia and to evaluate antinociceptive effects of drugs administered i.p. Monoarthritis was induced by injection of LPS intra-articularly into the right hind (RH limb ankle joint of C57BL/6 mice. Weight bearing changes and the effect of i.p. drug administration were analyzed in freely moving mice using the video-based CatWalk gait analysis system. Results In naïve mice indomethacin (5 to 50 mg/kg had no significant activity, minocycline (25 to 100 mg/kg produced hyperalgesia to thermal nociception, however, coadministration of minocycline 50 mg/kg with indomethacin 5 or 10 mg/kg produced significant antinociceptive effects in the hot plate test. A selective inhibitor of COX-1, FR122047 (10 mg/kg and a selective COX-2 inhibitor, CAY10404 (10 mg/kg had no significant antinociceptive activities to thermal nociception in naïve mice, however, coadministration of minocycline, with CAY10404 but not FR122047 produced significant antinociceptive effects. In mice with LPS-induced hyperalgesia vehicle, indomethacin (10 mg/kg or minocycline (50 mg/kg did not produce significant changes, however, coadministration of minocycline plus indomethacin resulted in antinociceptive activity. LPS-induced RH limb monoarthritis resulted in weight bearing (RH/left hind (LH limb paw pressure ratios and RH/LH print area ratios deficits. Treatment with indomethacin (1 mg/kg or

    2013-01-01

    Background Non-steroidal anti-inflammatory drugs (NSAIDs) are an effective and common treatment for chronic pain disorders, but long-term use is associated with risk of potentially life-threatening gastrointestinal adverse events (AEs). The proton pump inhibitor esomeprazole has been found to be effective for gastroprotection in NSAID users, but few long-term studies have been conducted in Japan. Methods This was an open-label, multicentre, single-arm, prospective 1-year study of treatment with esomeprazole (20 mg once daily) in Japanese patients (aged ≥20 years) with endoscopic evidence of previous peptic ulcer and receiving daily oral NSAID therapy (at a stable dose) for a chronic condition. Eligibility was not dictated by type of oral NSAID. The primary objective was to determine long-term safety and tolerability of esomeprazole. Efficacy for prevention of peptic ulcers was also determined (Kaplan-Meier method). All statistical analyses were descriptive. Results A total of 130 patients (73.1% women, mean age 62.1 years, 43.8% Helicobacter pylori-positive) received treatment with esomeprazole in addition to long-term NSAID therapy (most commonly for rheumatoid arthritis [n=42] and osteoarthritis [n=34]). Loxoprofen, meloxicam and diclofenac were the most commonly used NSAIDs; cyclo-oxygenase (COX)-2 selective agents were used by 16.2% of patients (n=21). Long-term compliance with esomeprazole (capsule counts) was >75% for the majority of patients. Although 16.9% of patients (n=22) experienced AEs judged to be possibly related to treatment with esomeprazole, they were mostly mild and transient. The most commonly reported possibly treatment-related AEs were abnormal hepatic function, headache, increased γ-glutamyltransferase levels and muscle spasms (2 patients each). Overall, 95.9% (95% confidence interval: 92.3, 99.4) of patients remained ulcer free at 1 year. Conclusion Long-term treatment with esomeprazole (20 mg once daily) is well tolerated and

    Proton-pump inhibitors such as omeprazole are a standard treatment to prevent non-steroidal anti-inflammatory drug-induced upper gastrointestinal mucosal injuries. However, it is unclear which drugs may protect against all NSAID-induced digestive-tract injuries. Here, we compare the efficacy of the gastromucoprotective drug irsogladine with omeprazole in preventing NSAID-induced esophagitis, peptic ulcers, and small-intestinal mucosal injury in healthy subjects. Thirty-two healthy volunteers were assigned to an irsogladine group (Group I; n = 16) receiving diclofenac sodium 75 mg and irsogladine 4 mg daily for 14 days, or an omeprazole group (Group O; n = 16) receiving diclofenac sodium 75 mg and omeprazole 10 mg daily for 14 days. Esophagitis and peptic ulcers were evaluated by esophagogastroduodenoscopy and small-intestinal injuries by capsule endoscopy, fecal calprotectin, and fecal occult blood before and after treatment. There was no significant difference between Group I and Group O with respect to the change in lesion score in the esophagus, stomach, and duodenum before and after treatment.NSAID treatment significantly increased the number of small intestinal mucosal breaks per subject by capsule endoscopic evaluation, from a basal level of 0.1 ± 0.3 up to 1.9 ± 2.0 lesions in Group O (p = 0.0002). In contrast, there were no significant changes in the mean number of mucosal breaks before and after co-treatment in Group I (0.3 ± 0.8 to 0.5 ± 0.7, p = 0.62), and the between-group difference was significant (p = 0.0040). Fecal calprotectin concentration, when the concentration before treatment was defined as 1, was significantly increased both in Group O (from 1.0 ± 0.0 to 18.1 ± 37.1, p = 0.0002) and Group I (from 1.0 ± 0.0 to 6.0 ± 11.1, p = 0.0280); the degree of increase in Group O was significantly higher compared with that in Group I (p<0.05). In addition, fecal occult blood levels increased significantly in Group O (p = 0.0018), but there

    Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed by veterinary surgeons for the treatment of canine osteoarthritis, and affected dogs may receive these drugs for long periods of time. Whilst short term administration of NSAIDs to dogs is linked to adverse events such as gastrointestinal haemorrhage and renal injury, reports of adverse events associated with their long-term administration are limited in the veterinary literature. This study aimed to investigate the attitudes towards the long term use of NSAIDs for canine osteoarthritis held by three groups who manage osteoarthritic dogs in the United Kingdom: dog owners, veterinary surgeons and veterinary nurses. A qualitative methodology was adopted, using semi-structured interviews and focus groups. Thematic analysis of these data identified three themes: awareness of potential risks; recognition of adverse events; and influence of risk perception on the use of NSAIDs. Awareness of, and concern about, the risk of adverse events associated with NSAID administration to dogs with osteoarthritis was high in all groups, with veterinary surgeons being one of a variety of information sources used by owners to acquire this knowledge. Veterinary surgeons described difficulty in recognising, managing and avoiding adverse events associated with NSAIDs. When adverse events occurred, a wide range of management approaches were adopted ranging from a brief drug respite to permanent cessation of administration of any NSAIDs to that dog. Commonly employed approaches to minimise risk included dose reduction and screening blood tests. This study describes a high level of concern about the risks associated with long term NSAID administration to dogs with osteoarthritis and highlights a diverse range of strategies employed to minimise these risks. The evidence base for these strategies is poor, and this may present a risk to animal welfare if the affected dogs are not receiving adequate analgesia. In order to

    Accidental falls in older individuals are a major health and research topic. Increased reaction time and impaired postural balance have been determined as reliable predictors for those at risk of falling and are important functions of the central nervous system (CNS). An essential risk factor for falls is medication exposure. Amongst the medications related to accidental falls are the non-steroidal anti-inflammatory drugs (NSAIDs). About 1-10% of all users experience CNS side effects. These side effects, such as dizziness, headaches, drowsiness, mood alteration, and confusion, seem to be more common during treatment with indomethacin. Hence, it is possible that maintenance of (static) postural balance and swift reactions to stimuli are affected by exposure to NSAIDs, indomethacin in particular, consequently putting older individuals at a greater risk for accidental falls. The present study investigated the effect of a high indomethacin dose in healthy middle-aged individuals on two important predictors of falls: postural balance and reaction time. Twenty-two healthy middle-aged individuals (59.5 ± 4.7 years) participated in this double-blind, placebo-controlled, randomized crossover trial. Three measurements were conducted with a week interval each. A measurement consisted of postural balance as a single task and while concurrently performing a secondary cognitive task and reaction time tasks. For the first measurement indomethacin 75 mg (slow-release) or a visually identical placebo was randomly assigned. In total, five capsules were taken orally in the 2.5 days preceding assessment. The second measurement was without intervention, for the final one the first placebo group got indomethacin and vice versa. Repeated measures GLM revealed no significant differences between indomethacin, placebo, and baseline in any of the balance tasks. No differences in postural balance were found between the single and dual task conditions, or on the performance of the dual task

    Non-steroidal anti-inflammatory drugs are the group of pharmaceuticals that is most often found in the environment, whereas estrogenic hormones are considered to be potent endocrine disruptors. However, the fate and persistence of these compounds in the environment are still unclear. In this study we propose two approaches for determining these compounds in environmental water samples: GC-MS using time windows and operating in selected ion-monitoring mode (SIM) and, for the first time, gas chromatography with electron capture detection (GC-ECD). The identification criteria of both methods fulfilled the requirements of Directive 2002/657/EC. The use of time windows improved the sensitivity of GC-MS measurements. In GC-MS analysis the pharmaceuticals were determined as trimethylsilyl, in GC-ECD as pentafluoropropionyl derivatives. The influence of such parameters as the type of reagent, type of solvent, reaction time, reaction temperature and microwave irradiation in a household microwave oven on the efficacy of silylation was investigated. Derivatization using N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA) and 1% trimethylchlorosilane (TMCS) in pyridine (1:1, v/v) for 30 min in 60 Degree-Sign C was found to be optimal. Optimization of the solid phase extraction procedure (SPE) confirmed that the application of Oasis HLB cartridges, the acidification of loading samples to pH 2 and the use of methanol as eluent gave the best absolute recoveries (ARs) of the target compounds. The following ARs of all the compounds were achieved: 58.2-106.8% in influent wastewater, 77.8-103.4% in effluent wastewater and 81.2-101.9% in surface water samples. Validation of the SPE-GC-MS method enables 13 pharmaceuticals to be determined with MDLs between 3.3 and 343.6 ng/L, depending on the analytes and matrices. GC-ECD analysis enables the determination of 6 pharmaceuticals in surface water samples with MDLs between 0.7 and 5.4 ng/L. The proposed methods were successfully used for

    In 2012, an Indian parliamentary committee reported that manufacturing licenses for large numbers of fixed dose combination (FDC) drugs had been issued by state authorities without prior approval of the Central Drugs Standard Control Organization (CDSCO) in violation of rules, and considered that some ambiguity until 1 May 2002 about states' powers might have contributed. To our knowledge, no systematic enquiry has been undertaken to determine if evidence existed to support these findings. We investigated CDSCO approvals for and availability of oral FDC drugs in four therapeutic areas: analgesia (non-steroidal anti-inflammatory drugs [NSAIDs]), diabetes (metformin), depression/anxiety (anti-depressants/benzodiazepines), and psychosis (anti-psychotics). This was an ecologic study with a time-trend analysis of FDC sales volumes (2007-2012) and a cross-sectional examination of 2011-2012 data to establish the numbers of formulations on the market with and without a record of CDSCO approval ("approved" and "unapproved"), their branded products, and sales volumes. Data from the CDSCO on approved FDC formulations were compared with sales data from PharmaTrac, a database of national drug sales. We determined the proportions of FDC sales volumes (2011-2012) arising from centrally approved and unapproved formulations and from formulations including drugs banned/restricted internationally. We also determined the proportions of centrally approved and unapproved formulations marketed before and after 1 May 2002, when amendments were made to the drug rules. FDC approvals in India, the United Kingdom (UK), and United States of America (US) were compared. For NSAID FDCs, 124 formulations were marketed, of which 34 (27%) were centrally approved and 90 (73%) were unapproved; metformin: 25 formulations, 20 (80%) approved, five (20%) unapproved; anti-depressants/benzodiazepines: 16 formulations, three (19%) approved, 13 (81%) unapproved; anti-psychotics: ten formulations, three (30

Data from the CDSCO on approved FDC formulations were compared with sales data from PharmaTrac, a database of national drug sales. We determined the proportions of FDC sales volumes (2011-2012 arising from centrally approved and unapproved formulations and from formulations including drugs banned/restricted internationally. We also determined the proportions of centrally approved and unapproved formulations marketed before and after 1 May 2002, when amendments were made to the drug rules. FDC approvals in India, the United Kingdom (UK, and United States of America (US were compared. For NSAID FDCs, 124 formulations were marketed, of which 34 (27% were centrally approved and 90 (73% were unapproved; metformin: 25 formulations, 20 (80% approved, five (20% unapproved; anti-depressants/benzodiazepines: 16 formulations, three (19% approved, 13 (81% unapproved; anti-psychotics: ten formulations, three (30

    Nonsteroidal anti-inflammatory drugs (NSAIDs) can induce renal complications in patients taking loop diuretics. This study investigated the pharmacokinetic/pharmacodynamic effects and safety profile of orally administered diclofenac sodium, ibuprofen and diclofenac epolamine topical patch (DETP) on furosemide in healthy adult subjects. This open-label, randomized, 5-way crossover study was conducted in 40 subjects (aged 19 - 45 y). Diclofenac (75 mg taken orally twice daily), DETP (1.3% applied topically twice daily), or ibuprofen (800 mg taken orally thrice daily) was administered for 3 consecutive days, followed by co-administration with furosemide (given intravenously as 20 mg/2 min). Plasma furosemide and NSAID concentrations, urine furosemide, sodium and potassium concentrations and urine output were determined throughout the 24 h period following furosemide administration. Orally administered ibuprofen significantly increased furosemide AUC(0-t) (37%) and AUC(0-inf) (36%) and decreased total body CL (27%), R(max) (19%) and CLR (23%) geometric mean ratios compared with furosemide control. Oral and topical diclofenac had no pharmacokinetic effects on furosemide. Ibuprofen increased sodium excretion (Ae(0-24), 16%) and decreased sodium R(max) (15%), and oral diclofenac decreased urine output (Vu(0-24), 15%). DETP had no effect on furosemide pharmacodynamics; total systemic exposure to diclofenac during DETP treatment was diclofenac. Treatments were generally safe, with 25 subjects reporting a total of 112 adverse events. Pharmacodynamic effects were seen with oral diclofenac (urine output) and ibuprofen (urine sodium excretion). Furosemide also affected plasma and urine pharmacokinetic profiles. Pharmacologic effects of DETP on furosemide were not observed under these conditions. Additional research is warranted to delineate the potential interactions of other NSAIDs with furosemide and other loop diuretics.

    Full Text Available Abstract Background High-risk prescribing of non-steroidal anti-inflammatory drugs (NSAIDs and antiplatelet agents accounts for a significant proportion of hospital admissions due to preventable adverse drug events. The recently completed PINCER trial has demonstrated that a one-off pharmacist-led information technology (IT-based intervention can significantly reduce high-risk prescribing in primary care, but there is evidence that effects decrease over time and employing additional pharmacists to facilitate change may not be sustainable. Methods/design We will conduct a cluster randomised controlled with a stepped wedge design in 40 volunteer general practices in two Scottish health boards. Eligible practices are those that are using the INPS Vision clinical IT system, and have agreed to have relevant medication-related data to be automatically extracted from their electronic medical records. All practices (clusters that agree to take part will receive the data-driven quality improvement in primary care (DQIP intervention, but will be randomised to one of 10 start dates. The DQIP intervention has three components: a web-based informatics tool that provides weekly updated feedback of targeted prescribing at practice level, prompts the review of individual patients affected, and summarises each patient's relevant risk factors and prescribing; an outreach visit providing education on targeted prescribing and training in the use of the informatics tool; and a fixed payment of 350 GBP (560 USD; 403 EUR up front and a small payment of 15 GBP (24 USD; 17 EUR for each patient reviewed in the 12 months of the intervention. We hypothesise that the DQIP intervention will reduce a composite of nine previously validated measures of high-risk prescribing. Due to the nature of the intervention, it is not possible to blind practices, the core research team, or the data analyst. However, outcome assessment is entirely objective and automated. There will

    To evaluate the effectiveness of non-steroidal anti-inflammatory drugs (NSAIDs) for the management of neck pain and associated disorders (NAD), whiplash-associated disorders, and non-specific low back pain (LBP) with or without radiculopathy. We systematically searched six databases from 2000 to 2014. Random pairs of independent reviewers critically appraised eligible systematic reviews using the Scottish Intercollegiate Guidelines Network criteria. We included systematic reviews with a low risk of bias in our best evidence synthesis. We screened 706 citations and 14 systematic reviews were eligible for critical appraisal. Eight systematic reviews had a low risk of bias. For recent-onset NAD, evidence suggests that intramuscular NSAIDs lead to similar outcomes as combined manipulation and soft tissue therapy. For NAD (duration not specified), oral NSAIDs may be more effective than placebo. For recent-onset LBP, evidence suggests that: (1) oral NSAIDs lead to similar outcomes to placebo or a muscle relaxant; and (2) oral NSAIDs with bed rest lead to similar outcomes as placebo with bed rest. For persistent LBP, evidence suggests that: (1) oral NSAIDs are more effective than placebo; and (2) oral NSAIDs may be more effective than acetaminophen. For recent-onset LBP with radiculopathy, there is inconsistent evidence on the effectiveness of oral NSAIDs versus placebo. Finally, different oral NSAIDs lead to similar outcomes for neck and LBP with or without radiculopathy. For NAD, oral NSAIDs may be more effective than placebo. Oral NSAIDs are more effective than placebo for persistent LBP, but not for recent-onset LBP. Different oral NSAIDs lead to similar outcomes for neck pain and LBP.

Allogeneic neonatal canine MSCs were obtained from fetal adnexa retrieved after C-section performed on healthy pregnant bitches. The dogs were randomly allocated to either the “MSCs group,” receiving an IA injection of MSCs after TPLO, followed by placebo for 1 month, or the “NSAIDs group,” receiving IA equivalent volume of MSCs vehicle after TPLO, followed by oral NSAID for 1 month. One of the three blinded evaluators assessed the dogs in each group before and after surgery (1, 3, and 6 months. Clinical score and gait and bone healing process were assessed. The data were statistically compared between the two groups for pre- and postoperative evaluations.ResultsFourteen dogs (nine in the MSCs group, five in the NSAIDs group completed the present study. No significant difference was observed between the groups preoperatively. No local or systemic adverse effect was observed after MSCs injection at any time point considered. At 1 month after surgery, bone healing scores were significantly higher in the MSCs group. At 1, 3, and 6 months after surgery, no significant difference was observed between the two groups for clinical scores and gait evaluation.ConclusionA single IA injection of allogeneic neonatal MSCs could be a safe and valuable postoperative alternative to NSAIDs for dogs requiring TPLO surgery, particularly for dogs intolerant to this class of

  2. Anti-Inflammatory Iridoids of Botanical Origin

    2012-01-01

    Inflammation is a manifestation of a wide range of disorders which include; arthritis, atherosclerosis, Alzheimer’s disease, inflammatory bowel syndrome, physical injury and infection amongst many others. Common treatment modalities are usually non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin, paracetamol, indomethacin and ibuprofen as well as corticosteroids such as prednisone. These however, may be associated with a host of side effects due to non-selectivity for cyclooxygenase (COX) enzymes involved in inflammation and those with selectivity may be highly priced. Thus, there is a continuing search for safe and effective anti-inflammatory molecules from natural sources. Research has confirmed that iridoids exhibit promising anti-inflammatory activity which may be beneficial in the treatment of inflammation. Iridoids are secondary metabolites present in various plants, especially in species belonging to the Apocynaceae, Lamiaceae, Loganiaceae, Rubiaceae, Scrophulariaceae and Verbenaceae families. Many of these ethnobotanicals have an illustrious history of traditional use alluding to their use to treat inflammation. Although iridoids exhibit a wide range of pharmacological activities such as cardiovascular, hepatoprotection, hypoglycaemic, antimutagenic, antispasmodic, anti-tumour, antiviral, immunomodulation and purgative effects this review will acutely focus on their anti-inflammatory properties. The paper aims to present a summary for the most prominent iridoid-containing plants for which anti-inflammatory activity has been demonstrated in vitro and / or in vivo. PMID:22414102

  5. Anti-inflammatory management for tendon injuries - friends or foes?

    2009-10-01

    Full Text Available Abstract Acute and chronic tendon injuries are very common among athletes and in sedentary population. Most physicians prescribe anti-inflammatory managements to relieve the worst symptoms of swelling and pain, including non-steroidal anti-inflammatory drugs, corticosteroids and physical therapies. However, experimental research shows that pro-inflammatory mediators such as prostaglandins may play important regulatory roles in tendon healing. Noticeably nearly all cases of chronic tendon injuries we treat as specialists have received non-steroidal anti-inflammatory drugs by their physician, suggesting that there might be a potential interaction in some of these cases turning a mild inflammatory tendon injury into chronic tendinopathy in predisposed individuals. We are aware of the fact that non-steroidal anti-inflammatory drugs and corticosteroids may well have a positive effect on the pain control in the clinical situation whilst negatively affect the structural healing. It follows that a comprehensive evaluation of anti-inflammatory management for tendon injuries is needed and any such data would have profound clinical and health economic importance.

OBJETIVO: Verificar o efeito do uso profilático de ibuprofeno sobre desempenho em uma sessão de treino de força. MÉTODOS: Um ensaio clínico, cruzado, randomizado, duplo-cego e placebo-controlado foi desenvolvido com 12 praticantes regulares de treino de força do sexo masculino, os quais realizaram uma sessão de treino após a ingestão de ibuprofeno (1,2 g e uma outra após a ingestão de placebo. Seis séries dos exercícios supino e agachamento foram realizadas em cada sessão de treino com uma carga constante correspondente a 65% da 1RM de cada exercício. O desempenho no treinamento foi mensurado através do número de repetições que os voluntários conseguiram realizar em cada série de exercício a cada sessão de treino de força. RESULTADOS: Não foram verificadas diferenças significativas de desempenho no treino de força com a administração prévia de placebo ou ibuprofeno (p > 0,05. CONCLUSÃO: A ingestão de ibuprofeno nos parâmetros de administração adotados pelo presente estudo não promove qualquer tipo de alteração na tolerância ao exercício em uma sessão isolada de treino de força, o que contraria a indicação dessa substância para fins ergogênicos no treino de força.INTRODUCTION: Non-steroidal anti-inflammatory drugs, such as ibuprofen, have been used by athletes of several sports modalities in order to increase athletic performance.

    Full Text Available Non-steroidal anti-inflammatory drugs are drugs of choice for chronic pain, which is most common in chronic conditions, rheumatism in particular. According to  current recommendations, these medications should be used continuously or intermittently, and their choice should be tailored to each patient. Unfortunately, non-steroidal anti-inflammatory drugs have multiple adverse effects ranging from the most insignificant dyspepsia to severe upper gastrointestinal bleeding. Therefore, gastroscopy and, in the case of confirmed Helicobacter pylori infection, eradication is advisable for planned long-term treatment with these agents. Long-term use of proton pump inhibitors is recommended in rheumatic patients chronically receiving non-selective non-steroidal anti-inflammatory drugs, while celecoxib (a selective COX-2 inhibitor combined with proton pump inhibitor should be administered in patients at high risk of gastrointestinal complications. In rheumatic patients, the type of non-steroidal anti-inflammatory drug and the route of its administration should be tailored to each patient in terms of strength and duration of drug action, the type of disease and comorbidities as well as contraindications. Adverse gastrointestinal effects are due to the mechanism of action of non-steroidal anti-inflammatory drugs, and therefore independent of the route of administration. The use of proton pump inhibitors with cardioprotective doses of aspirin should be limited to patients with risk factors for gastrointestinal complications. High non-steroidal anti-inflammatory drug doses are limited to gout attack, acute pain and axial spondyloarthropathy showing high clinical activity. In other cases, the lowest effective non-steroidal anti-inflammatory drug dose is recommended. Advancing age is characterised by impairment in the function of all organs, therefore elderly patients should receive lower non-steroidal anti-inflammatory drug

    NSAIDs are largely used for the treatment of a huge variety of clinical conditions in order to relieve symptoms related to inflammation.The use of NSAIDs is associated with a potential increased risk of gastrointestinal and cardiovascular complications.The cardiovascular risk related to NSAIDs administration is often underestimated and it is frequently believed to be less important than the gastrointestinal risk. Adverse effects of NSAIDs are specifically related to their underlying mechanisms of action.The most plausible mechanism underlying the cardiovascular risk of NSAIDs has been identified in the profound inhibition of COX-2-dependent PGI2 in the presence of incomplete and intermittent inhibition of platelet COX-1. Nevertheless, the cardiovascular risk related to the use of NSAIDs is not only due to the COX-2 selectivity. An important determinant of the clinical effects of NSAIDs depends on the pharmacokinetic features of the different drugs such as half-life, and type of formulations, which can influence the extent and duration of patient exposure to COXisozyme inhibition. The aim of this review is to analyse the mechanisms behind the cardiovascular risk of different NSAIDs.

  7. Radioprotection: the non-steroidal anti-inflammatory drugs (NSAIDs) and prostaglandins.

    Clinical and experimental studies of the acute and late effects of radiation on cells have enhanced our knowledge of radiotherapy and have led to the optimisation of radiation treatment schedules and to more precise modes of radiation delivery. However, as both normal and cancerous tissues have similar response to radiation exposure, radiation-induced injury on normal tissues may present either during, or after the completion of, the radiotherapy treatment. Studies on both NSAIDs and prostaglandins have indeed shown some evidence of radioprotection. Both have the potential to increase the survival of cells but by entirely different mechanisms. Studies of cell kinetics reveal that cells in the mitotic (M) and late G2 phases of the cell cycle are generally most sensitive to radiation compared with cells in the early S and G1/G0 phases. Furthermore, radiation leads to a mitotic delay in the cell cycle. Thus, chemical agents that either limit the proportion of cells in the M and G2 phases of the cell cycle or enhance rapid cell growth could in principle be exploited for their potential use as radioprotectors to normal tissue during irradiation. NSAIDs have been shown to exert anti-cancer effects by causing cell-cycle arrest, shifting cells towards a quiescence state (G0/G1). The same mechanism of action was observed in radioprotection of normal tissues. An increase in arachidonic acid concentrations after exposure to NSAIDs also leads to the production of an apoptosis-inducer ceramide. NSAIDs also elevate the level of superoxide dismutase in cells. Activation of heat shock proteins by NSAIDs increases cell survival by alteration of cytokine expression. A role for NSAIDs with respect to inhibition of cellular proliferation possibly by an anti-angiogenesis mechanism has also been suggested. Several in-vivo studies have provided evidence suggesting that NSAIDs may protect normal tissues from radiation injury. Prostaglandins do not regulate the cell cycle, but they do have a variety of effects on cell growth and differentiation. PGE(2) mediates angiogenesis, increasing the supply of oxygen and nutrients, essential for cellular survival and growth. Accordingly, PGE(2) at sufficiently high plasma concentrations enhances cellular survival by inhibiting pro-inflammatory cytokines such as TNF-alpha and IL-1beta. Thus, PGE(2) acts as a modulator, rather than a mediator, of inflammation. Prospective studies have suggested the potential use of misoprostol, a PGE(1) analogue, before irradiation, in prevention of radiation-induced side effects. The current understanding of the pharmacology of NSAIDs and prostaglandins shows great potential to minimise the adverse effects of radiotherapy on normal tissue.

  9. Relaxation pathways of photoexcited non-steroidal anti-inflammatory drugs: flufenamic and mefenamic acids

    El-Kemary, Maged A.

    2003-01-01

    The photophysical behavior of flufenamic (FLF) and mefenamic (MEF) acids as a function of solvent is investigated by using steady-state and time-resolved measurements. The results suggest that there is a deactivation pathway that involves a change in molecular conformation and the nature of which is strongly dependent on the solvent polarity. In non-polar solvent the deactivation of the excited singlet states proceeds via excited state intramolecular proton transfer (ESIPT). In polar aprotic solvents the results indicate that the new emission band that appears in the long wavelength region is assigned to a twisting intramolecular charge-transfer (TICT) state. In agreement with the experimental results, MO calculations suggest that the degree of twisting of substituted aniline moiety around C-N bond is higher for FLF than for MEF. Very efficient pathway for deactivation of the singlet excited states has been observed in polar protic solvents, indicating that the excited state deactivates partly via intermolecular hydrogen-bonding, which competes with the TICT

In the grouping process the geographical, demographic, social-economic and sociological principles are frequently used. Segmentation is the method to represent the difference on the basis of defined principles. 107 persons were participated in the interviews, among them 93 women and 14 men. Their age from 20-up to 60, among them 43 participants were with high education, 22 with technical and 20 with secondary education. The majority of population (51,4%) gets the information about new medicines by advertisements. The sources of getting information are equally from doctors (23,37%) and the chemists (23,37%); from other means this index is very low (1,86%). The population gives the priority to import insteroidic antiphlogistic medical means (45, 78%); less to native medicines (24,3%) and 29,9 % of participants can't give the answer on this question. The population mostly use tablets (78,5%), ampoules (11,21%); capsules (5,6%), ointment (3,75%) and candles (9,94%). Our study showed, that population more often use aspirin, diklophenak, indometacin, ibuprophen, ketoprofen.

    Pain in osteoarthritis of the big weight bearing joints is either derived from periarticular ligaments, tendons, fascias, muscles, bursae--periarthropathy as sign of decompensation or from the reactive synovitis with or without effusion. NSAIDs (ibuprofen, diclofenac, indometacin, some salicylates, etofenamate and piroxicam) have demonstrated relevant advantages of the percutaneous route over the systemic one in soft tissue rheumatism. NSAIDs, mentioned above, locally administered as cream, gel or spray, quickly penetrate through the corneal layer of the skin and the site of application, reach highly effective concentrations in subcutis, fascias, tendons, ligaments and muscles, less in joint-capsule and -fluid indicating direct penetration. The blood levels of topical NSAIDs are extremely low with no systemic side effects, especially no gastric toxicity; however, local skin irritation is observed (1 to 2%). In contrast to this, systemic (oral) NSAIDs lead primarily via high blood levels to a lower concentration--only one tenth--in periarticular soft tissues with a high incidence of side effects. In conclusion the percutaneous application of certain NSAIDs has become a well established therapeutic regimen in painful osteoarthritis and in all other inflammatory degenerative and posttraumatic alterations of soft tissue structure.

    Inclusion of phenacetin among 'proven' human carcinogens by the IARC in 1987, raised concerns about the carcinogenic potential of acetaminophen, its major metabolite. Acetaminophen has been implicated as a possible causal agent in the development of cancer of the renal pelvis. The bladder and renal pelvis, which derive from the same embryological structure, share the same transitional type of epithelium. Past studies have been inconclusive on the possible relationship among these analgesics and bladder cancer but no large, highly detailed study of this association has been conducted. A population-based case-control study conducted in Los Angeles, California, involved 1514 incident bladder cancer cases and an equal number of controls who were matched to the index cases by sex, date of birth (within 5 years) and race. Detailed information on medication use and prior medical conditions was collected through in-person interviews. Regular use of analgesics was not associated with an increased risk of bladder cancer in either men or women. In fact, compared with non- or irregular users, regular analgesic users were at a decreased risk of bladder cancer overall (odds ratio (OR) = 0.81, 95% confidence interval (CI) = 0.68-0.96). However, there were clear differences in both the direction and strength of the associations between the different formulation classes of analgesics and bladder cancer risk. Intake of phenacetin was positively related to bladder cancer risk in a dose-dependent manner while intake of its major metabolite in humans, acetaminophen, was unrelated to risk. Intake of all classes of NSAIDs, except pyrazolon derivatives, were negatively associated with bladder cancer risk, with suggestive evidence that the protective effect varies in strength by subcategories of formulation. Acetic acids seemed to exhibit the strongest protective effect, whereas aspirin/other salicylic acids and oxicam showed the weakest protection.

    Pomegranate (Punica granatum L.) has been used for centuries for the treatment of inflammatory diseases. However, there is a lack of comprehensive information focused on the properties of a certain pomegranate (poly)phenolic profile to cure pain and gastric injury induced by anti-inflammatory drugs. This study investigated the systemic effects of different doses of a HPLC-characterized pomegranate extract on the formalin-induced nociceptive behavior in mice. The effect of the extract against gastric injury caused by non-steroidal anti-inflammatory drugs and ethanol was also assessed. Pomegranate reduced nociception in both phases of the formalin test, suggesting central and peripheral activities to inhibit nociception. Indomethacin-induced gastric injury was not produced in the presence of pomegranate, which also protected against ethanol-induced gastric lesions. The present results reinforce the benefits of pomegranate (poly)phenolics in the treatment of pain as well as their anti-inflammatory properties.

    In this second article we describe the more interesting pharmacological interactions in dental practice based on the prescription of analgesic narcotics, paracetamol and non-selective non-steroid anti-inflammatory drugs (NSAI) (which inhibit cyclooxigenase 1 -COX 1- and cyclooxigenase 2 -COX 2-) and selective NSAIs (COX 2 inhibitors). The importance of preventing the appearance of these pharmacological interactions is because these are medicaments prescribed daily in odontology for moderate pain treatment and inflammation in the oral cavity. Paracetamol can interact with warfarin and therefore care should be taken with chronic alcoholic patients. All NSAIs reduce renal blood flow and consequently are capable of reducing the efficacy of medicaments used for treating arterial hypertension, which act via a renal mechanism. Especial attention should be taken considering the risk of interaction between the antagonists of AT1 receptors of angiostensin II (ARAII) and the NSAIs.

  5. Radiation as anti-inflammatory agent

    Nagaraju, S.

    2012-01-01

    Radiation is used for many disease treatments, recently works are being conducted on benefits of radiation for treating inflammatory diseases but clinical practices are limited. There are always risks involved with radiation. Risks could include, but are not limited to, potential late effects, even the induction of tumor formation as well as changes in normal tissues. Recently it has been reported in three randomized double blind studies using radiation for patients with painful degenerative joint diseases. All the three studies showed improvement in symptoms within months, suggesting the some with acute disease improve spontaneously. The treatment actually did not improve the architecture of the joint, yet it decreased painful symptoms. Pathologic evaluation weeks later showed disappearance of edema in the joint space with diminished inflammation and joint swelling. Thus it is postulated some therapeutic effects of radiotherapy for inflammatory diseases are due to the ability of radiation to inhibit cell proliferation. Sometimes inflammatory cells which affect the inflammatory joint space. This may have long-term consequences if it exists during critical periods. This may explain the effectiveness of radiotherapy in prevention of inflammatory disease. It is also noted that the effects of very low radiation doses of less than 500 rads on acute inflammation formations are most spectacular. Mitigation of pain, edema and erythema occurs so fast and after such low doses that it is inconceivable that cell death or inhibition of proliferation could play any role in this process. The optimal therapeutic effects of low dose irradiation occur in the very early stages of inflammation when vascular dilatation, edema formation and leukocyte invasion are beginning. There certainly can be adverse effects from radiation, yet it has to be noted that more than 1,60,000 people die annually of adverse effects of simple non-steroidal anti-inflammatory pills that are available in the

    Chronic inflammation is a critical factor in the pathogenesis of many inflammatory disease states including cardiovascular disease, cancer, diabetes, degenerative joint diseases and neurodegenerative diseases. Chronic inflammatory states are poorly understood, however it is known that dietary habits can evoke or attenuate inflammatory responses. Popular methods to deal with inflammation and its associated symptoms involve the use of non steroidal anti-inflammatory drugs, however the use of these drugs are associated with severe side effects. Therefore, investigations concerned with natural methods of inflammatory control are warranted. A traditional Mediterranean diet has been shown to confer some protection against the pathology of chronic diseases through the attenuation of pro-inflammatory mediators and this has been partially attributed to the high intake of virgin olive oil accompanying this dietary regime. Virgin olive oil contains numerous phenolic compounds that exert potent anti-inflammatory actions. Of interest to this paper is the recently discovered phenolic compound oleocanthal. Oleocanthal is contained in virgin olive oil and possesses similar anti-inflammatory properties to ibuprofen. This pharmacological similarity has provoked interest in oleocanthal and the few studies conducted thus far have verified its anti-inflammatory and potential therapeutic actions. A review of the health benefits of the Mediterranean diet and anti-inflammatory properties of virgin olive oil is presented with the additional emphasis on the pharmacological and anti-inflammatory properties of the phenolic compound oleocanthal.

    Traditional non-steroidal anti-inflammatory drugs (NSAIDs) and COX-2 selective inhibitors are among the most widely used drugs. However, their significant side effects in gastrointestinal and cardiovascular systems limited the use of these drugs. Recently, research and development of NO-donating NSAIDs (NO-NSAIDs) have become one of the most important strategies to reduce these side effects. NO-NSAIDs may exert a broad range of positive effects in terms of NO-mediated gastrointestinal and cardiovascular safety as well as comparable or increased anti-inflammatory, analgesic properties relative to NSAIDs. This review briefly deals with chemistry of NO-NSAIDs, more details are focused on biological significance, mechanism of action, and therapeutic potential of this novel class of drugs.

    Salvia officinalis L. leaves, obtained from four plant populations of different origin, were investigated for their topical anti-inflammatory properties. The n-hexane and the chloroform extracts dose-dependently inhibited the Croton oil-induced ear oedema in mice, the chloroform extracts being the most active. By contrast, the methanol extracts showed a very low effect and the essential oil was inactive. Chemical and pharmacological investigation of the most potent chloroform extract, issued from an autochthonous sage population grown in the submediterranean climatic region of Slovenia, revealed ursolic acid as the main component involved in its anti-inflammatory activity. The anti-inflammatory effect of ursolic acid (ID50 = 0.14 microMoles/cm2) was two fold more potent than that of indomethacin (ID50 = 0.26 microMoles/cm2), which was used as a reference non-steroidal anti-inflammatory drug (NSAID). The content of ursolic acid in sage and sage-based remedies for the topical treatment of inflammatory diseases is proposed as a parameter for quality control purposes.

    Inflammatory mediators alter the local environment of tumors, known as the tumor microenvironment. Mechanistically, chronic inflammation induces DNA damage, but understanding this hazard may help in the search for new chemopreventive agents for gastrointestinal (GI) cancer which attenuate inflammation. In the clinic, GI cancer still remains a major cause of cancer-associated mortality, chemoprevention with anti-inflammatory agents is thought to be a realistic approach to reduce GI cancer. Proton pump inhibitors, monoclonal antibodies targeting tumor necrosis factor-alpha, anti-sense targeted smad7 and non-steroidal anti-inflammatory agents have been investigated for their potential to prevent inflammation-based GI cancer. Besides these, a wide variety of natural products have also shown potential for the prevention of GI cancer. In this review, the authors will provide insights to explain the mechanistic connection between inflammation and GI cancer, as well as describe a feasible cancer prevention strategy based on anti-inflammatory treatments.

    The quintessential biological response to disease is inflammation. It is a driver and an important element in a wide range of pathological states. Pharmacological management of inflammation is therefore central in the clinical setting. Anti-inflammatory drugs modulate specific molecules involved in the inflammatory response; these drugs are traditionally classified as steroidal and non-steroidal drugs. However, the effects of these drugs are rarely limited to their canonical targets, affecting other molecules and altering biological functions with system-wide effects that can lead to the emergence of secondary therapeutic applications or adverse drug reactions (ADRs). In this study, relationships among anti-inflammatory drugs, functional pathways, and ADRs were explored through network models. We integrated structural drug information, experimental anti-inflammatory drug perturbation gene expression profiles obtained from the Connectivity Map and Library of Integrated Network-Based Cellular Signatures, functional pathways in the Kyoto Encyclopedia of Genes and Genomes (KEGG) and Reactome databases, as well as adverse reaction information from the U.S. Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). The network models comprise nodes representing anti-inflammatory drugs, functional pathways, and adverse effects. We identified structural and gene perturbation similarities linking anti-inflammatory drugs. Functional pathways were connected to drugs by implementing Gene Set Enrichment Analysis (GSEA). Drugs and adverse effects were connected based on the proportional reporting ratio (PRR) of an adverse effect in response to a given drug. Through these network models, relationships among anti-inflammatory drugs, their functional effects at the pathway level, and their adverse effects were explored. These networks comprise 70 different anti-inflammatory drugs, 462 functional pathways, and 1,175 ADRs. Network-based properties, such as degree

    Non-steroidal anti-inflammatory drugs (NSAIDS) are clinically used as anti-inflammatory, analgesic and antipyretic agents but they have the drawbacks such as gastric irritation and gastric ulceration. Recently, quinoline derivatives have shown significant anti-inflammatory and less ulcerogenic activity. The present study deals with the synthesis and pharmacological assessment of a series of novel quinoline derivatives bearing azetidinones scaffolds as anti-inflammatory and analgesic agents. A series of newer 3-chloro-1-(substituted)-4-(tetrazolo [1,5-a]quinolin-4- yl)azetidin-2-one derivatives (6a-l) was synthesized starting with acetanilide (1). Initially, acetanilide (1) was allowed to react with Vilsmeier-Haack reagent (DMF + POCl3) to form 2- chloro-3-formyl quinoline (2). The 2-chloro-3-formyl quinoline (2) was further treated with p-toluenesulphonic acid and sodium azide which yielded Tetrazolo [1,5-1] quinoline-4- carbaldehyde (3). The reaction of formyl group with various substituted amines (4a-l) formed corresponding Schiff base intermediates (5a-l), which were further allowed to react with chloroacetyl chloride to produce 3-chloro-1-(substituted)-4-(tetrazolo [1,5-a]quinolin-4-yl) azetidin-2-one derivatives (6a-l). The structure of the final analogues (6a-l) has been confirmed on the basis of elemental analysis, IR, 1H NMR, 13C NMR and mass spectra. All the synthesized compounds were evaluated for their anti-inflammatory and analgesic activities by using carrageenan induced rat paw model and Eddy's hot plate method respectively. All the values of elemental analysis, IR, 1H NMR, 13C NMR and mass spectra were found to be prominent. The anti-inflammatory activity test revealed that 3-chloro-1-(4-methoxyphenyl)- 4-(tetrazolo[1,5-a] quinolin-4-yl)azetidin-2-one (6b), 3-chloro-1-(2-methoxyphenyl)- 4-(tetrazolo[1,5-a]quinolin-4-yl)azetidin-2-one (6a) exhibited significant anti-inflammatory and analgesic activity as compared to control group.

    Inflammation is the symptom of many diseases like rheumatoid arthritis and osteoarthritis. Many side effects are associated with the Non-Steroidal Anti-inflammatory Drugs (NSAIDs) used as conventional treatment for these conditions. In Unani, there are large number of single and compound drugs for inflammatory conditions. One dosage form of Unani system of medicine is named as Zimad in which paste is formed by mixing powder in oil, water, herbal extract. Zimadat is prepared just before application and used in many disease conditions as resolving, styptic, astringent, and antiseptic. As the pre-application procedure is difficult and also complicated for patients, hence, the present study attempted to modify the form of Zimad into cream. Various batches of cream of Zimad Mohallil were prepared by using extracts of the formulation and by adding additives. Various physicochemical parameters of prepared cream were carried and compared with market cream. The optimized cream of Zimad Mohallil (F 4 ) was selected after preliminary tests and evaluated further. The optimized cream showed good results in physicochemical parameters equivalent to market sample. Zimad Mohallil was converted into convenient cream form by adding minimum additives and benefits could be achieved without any hassle and cumbersome work, which is encountered in crude or paste form. The optimized cream was equivalent to standard market cream. Copyright © 2017 Transdisciplinary University, Bangalore and World Ayurveda Foundation. Published by Elsevier B.V. All rights reserved.

    Full Text Available Non Steroidal Anti Inflammatory Drugs (NSAID have been associated with a sudden and sustained rise in the incidence of gastrointestinal ulcer complications. The aim of the study was to reveal the endoscopical abnormalities found in the duodenum & proximal jejunum due to NSAID. Thirty eight patients taking NSAID for their arthritis or rheumatism were included in this study. Gastro-duodeno-jejunoscopy was done with Olympus PCF-10. The endoscopical appearances of NSAID entero gastropathy were evaluated with a scoring system. The NSAID-entero-gastropathy appearances were endoscopically seen as hyperemia, erosion and ulcer. From all patient recruited, 7.9% complaint of diarrhea and 71.1% complaint of dyspepsia. Endoscopically, in the duodenal bulb we found 79% cases of hyperemia, 39.5% cases of erosion and 7.9% cases of ulcer. In the second part (descending part of the duodenum we found 28.9% cases of hyperemia, 15.8% cases of erosion and 2.6% case of ulcer. In the jejunum, we found 7.9% cases of hyperemia, 2.6% case of erosion and no ulcer. It is concluded that the most frequent abnormal endoscopical appearances in NSAID- enteropathy was hyperemia. The most frequent site of NSAID-enteropathy abnormal findings was in the duodenal bulb. (Med J Indones 2005; 14: 225-9Keywords: NSAID-enteropathy, endoscopical appearances.

    Inducible cyclooxygenase (COX-2) has been implicated in the process of inflammation and carcinogenesis. Chamomile has long been used in traditional medicine for the treatment of inflammatory diseases. In this study we aimed to investigate whether chamomile interferes with the COX-2 pathway. We used lipopolysaccharide (LPS)-activated RAW 264.7 macrophages as an in vitro model for our studies. Chamomile treatment inhibited the release of LPS-induced prostaglandin E(2) in RAW 264.7 macrophages. This effect was found to be due to inhibition of COX-2 enzyme activity by chamomile. In addition, chamomile caused reduction in LPS-induced COX-2 mRNA and protein expression, without affecting COX-1 expression. The non-steroidal anti-inflammatory drug, sulindac and a specific COX-2 inhibitor, NS398, were shown to act similarly in LPS-activated RAW 264.7 cells. Our data suggest that chamomile works by a mechanism of action similar to that attributed to non-steroidal anti-inflammatory drugs. These findings add a novel aspect to the biological profile of chamomile which might be important for understanding the usefulness of aqueous chamomile extract in the form of tea in preventing inflammation and cancer.

    Over the past two decades, it has become well accepted that sepsis exhibits two, oftentimes concomitant, inflammatory stages; a pro-inflammatory phase, referred to as the systemic inflammatory response syndrome (SIRS), and an anti-inflammatory phase, called the compensatory anti-inflammatory response syndrome (CARS). Considering that therapeutic interventions designed to attenuate the pro-inflammatory septic response have generally failed, much recent research has gone into understanding how and why septic patients display immunosuppressive characteristics, what the significance of septic immunosuppression may be and if there exists any therapeutic targets within the CARS. Herein, we describe the potential mechanisms of the immunosuppressive/CARS phase of sepsis by discussing what anti-inflammatory agents, receptors and cell populations are currently believed to contribute to CARS.

    Full Text Available Over the past decade, zebrafish (Danio rerio have emerged as an attractive model for in vivo drug discovery. In this study, we explore the suitability of zebrafish larvae to rapidly evaluate the anti-inflammatory activity of natural products (NPs and medicinal plants used in traditional medicine for the treatment of inflammatory disorders. First, we optimized a zebrafish assay for leukocyte migration. Inflammation was induced in four days post-fertilization (dpf zebrafish larvae by tail transection and co-incubation with bacterial lipopolysaccharides (LPS, resulting in a robust recruitment of leukocytes to the zone of injury. Migrating zebrafish leukocytes were detected in situ by myeloperoxidase (MPO staining, and anti-inflammatory activity was semi-quantitatively scored using a standardized scale of relative leukocyte migration (RLM. Pharmacological validation of this optimized assay was performed with a panel of anti-inflammatory drugs, demonstrating a concentration-responsive inhibition of leukocyte migration for both steroidal and non-steroidal anti-inflammatory drugs (SAIDs and NSAIDs. Subsequently, we evaluated the bioactivity of structurally diverse NPs with well-documented anti-inflammatory properties. Finally, we further used this zebrafish-based assay to quantify the anti-inflammatory activity in the aqueous and methanolic extracts of several medicinal plants. Our results indicate the suitability of this LPS-enhanced leukocyte migration assay in zebrafish larvae as a front-line screening platform in NP discovery, including for the bioassay-guided isolation of anti-inflammatory secondary metabolites from complex NP extracts.

    Non-steroidal anti-inflammatory drugs (NSAIDs) have been widely used for the modulation of the inflammatory response. However, a number of facts involving the occurrence of gastrointestinal lesions have limited the chronic use of NSAIDs. In order to diminish the occurrence of gastrointestinal damage caused by NSAIDs, the combination of NSAIDs with the H2 receptor blocker, cimetidine, has been evaluated. The anti-inflammatory and ulcerogenic effects of indomethacin and tenoxicam in association with or without cimetidine were determined at pre-clinical levels. It was observed that the group of animals treated with indomethacin and cimetidine, or tenoxicam and cimetidine (10 mg/kg, p.o.) demonstrated a significant reduction (P < 0.05, ANOVA followed by Tukey-Kramer multiple comparison test) of type-III gastric ulcers. Furthermore, indomethacin or tenoxicam (10 mg/kg, p.o.) in association with cimetidine increased the anti-inflammatory activity. The group, which received indomethacin and cimetidine presented the best performance in decreasing the inflammatory process (P < 0.05, ANOVA followed by Tukey-Kramer multiple comparison test).

  7. Anti-inflammatory responses of resveratrol.

    2007-09-01

    Resveratrol (trans-3,4',5-trihydroxystilbene), a natural polyphenolic, non-flavonoid antioxidant, is a phytoalexin found in many plants including grapes, nuts and berries. Recent studies have documented that resveratrol has various health benefits, such as cardiovascular and cancer preventive properties. However, the experimental basis for such health benefit is not fully understood. One of the possible mechanisms for its protective activities is by down regulation of the inflammatory responses. That includes the inhibition of synthesis and release of pro-inflammatory mediators, modifications of eicosanoid synthesis, inhibition of some activated immune cells, or inhibiting the enzymes, such as cyclooxygenase-1 (COX-1) or cyclooxygenase-2 (COX-2), which are responsible for the synthesis of pro-inflammatory mediators through the inhibitory effect of resveratrol on transcription factors like nuclear factor kappaB (NFkappaB) or activator protein-1 (AP-1). Being a phenolic compound, resveratrol certainly possesses a low bioavailability and most importantly, a rapid clearance from the plasma. Recent growing interest in varying protective nature of resveratrol may clinically also hold a respectable position as a better alternative for anti-inflammatory drugs. The purpose of this review is to provide evidence that resveratrol exhibits potent anti-inflammatory activity and also to explain the underling mechanism for both resveratrol- induced cardioprotective and anti-inflammatory properties. While it is true that the cardioprotective properties of resveratrol are likely attributable, at least in part, to its anti-inflammatory properties, the mechanisms discussed address foremost mechanisms for the anti-inflammatory activity which, in turn, is responsible for cardioprotection.

    The aim of this review paper was to summarise some commonly available natural products and their anti-inflammatory activity. We have collected data from MEDLINE, Current Contents and scientific journals, which included 92 publications. There are numerous natural products detailed in this literature; however we have summarized a few of the most commonly available and potent ones. In this paper, the natural products with anti-inflammatory activity including curcumin, parthenolide, cucurbitacins, 1,8-cineole, pseudopterosins, lyprinol, bromelain, flavonoids, saponins, marine sponge natural products and Boswellia serrata gum resin were reviewed. Natural products play a significant role in human health in relation to the prevention and treatment of inflammatory conditions. Further studies are being conducted to investigate the mechanism of action, metabolism, safety and long term side effect of these natural products, as well as interactions between these natural products with food and drug components.

    Aging and drug-induced side effects may contribute to deteriorate mitochondrial bioenergetics in many tissues, including kidney and liver. One possibility is that the combination of both aging and drug toxicity accelerates the process of mitochondrial degradation, leading to progressive bioenergetic disruption. We therefore analyzed in vitro kidney (KM) and liver (LM) mitochondrial response to salicylate and diclofenac in old and adult animals. Male-Wistar adult (19-wks) and aged (106-wks) rats were used. In vitro endpoints of oxygen consumption and membrane potential were evaluated in non-treated conditions (vehicle) and in the presence of salicylate (0.5mM) and diclofenac (50μM). The susceptibility to calcium-induced permeability transition pore (MPTP) was assessed. Aconitase and C, -SH and MDA contents were measured. Apoptotic signaling was followed by measuring caspase 3, 8 and 9 activities, Bax, Bcl2 and CypD expression. ANT content was semi-quantified. In general, animal age alone compromised KM state 3 and LM ADP lag phase while resulting in decreased resistance to the MPTP. Aging decreased LM CypD and increased Mn-SOD. Kidney caspase 9-like activity was lower in aged group. Salicylate and diclofenac induced KM and LM dysfunction. ADP lag phase in KM was further increased in the aged group in the presence of diclofenac. No further impairments were observed regarding drug toxicity adding to the aging process. Aging impaired KM and LM function despite no detected alterations on oxidative stress and apoptosis. However, aging did not further exacerbate KM and LM frailty induced by salicylate and diclofenac. © 2013.

    The aim of the present study was to evaluate the aqueous solubility enhancement properties of polypropylene oxide cored PAMAM (PPO@PAMAM) dendrimers. The solubility of NSAIDs (Ketoprofen, Ibuprofen and Diflunisal) was investigated in the presence of PPO@PAMAM dendrimers at room temperature in buffer solution. The effects of dendrimer concentration, generation and core size on the solubility of NSAIDs have been investigated. The experimental results showed that the solubility of the NSAIDs was approximately proportional to dendrimer concentration and generation. In addition, the effect of core size on the solubility of NSAIDs in constant generation and concentration of PPO@PAMAM dendrimer was Ketoprofen>Diflunisal>Ibuprofen. Under optimized conditions, PPO@PAMAM dendrimers are highly effective solubility enhancer for NSAIDs due to its new polypropylene oxide core. Copyright © 2013 Elsevier B.V. All rights reserved.

  18. The impact of combinations of non-steroidal anti-inflammatory drugs and anti-hypertensive agents on blood pressure.

    2014-01-01

    Nowadays NSAIDs are the most frequently used groups of drugs, especially because of their availability. Their consumption is high among older people, who are much more sensitive to the side effects, and who are often also taking other drugs which can interact with them. Moreover, the majority of the older population is suffering from hypertension. This could well explain the commonly encountered experience of drug interaction between NSAIDs and antihypertensive drugs, which is very common in clinical practice. The severity of this drug interaction is classified as class C, with a recommendation to monitor therapy. However, even a minor long-term increase in blood pressure can significantly increase the risk of cardiovascular mortality, while mortality rates can possibly be reduced by sufficiently effective treatment of hypertension. Therefore, in clinical practice, this type of interaction should not be overlooked as a major cause of failure of hypertension treatment in older patients, as well in many cases in general. The present article focusses on the mechanism and the degree of influence on the blood pressure of particular types of antihypertensive agents used in combination with NSAID. Not all groups of antihypertensive drugs are affected to the same degree; some are more affected, and others, such as calcium channel blockers, are not affected at all. Similarly, not every NSAID increases blood pressure. Many studies, some of which are analyzed in this article, present evidence of the degree of the influence NSAIDs have on blood pressure.

    Full Text Available Background: Acute puerperal metritis (APM is a potentially life threatening, painful disease and is often treated with third-generation cephalosporins (Machado et al., 2014; Stojkov et al., 2015. An increasing antibiotic resistance is well documented and associated with decreasing clinical efficacy, animal welfare and economic consequences (Thomson et al., 2004. Hence, there is the need to evaluate alternative therapies to antibiotics.Objective: The objective of this study was to assess the efficacy of ketoprofen for the treatment of APM compared with ceftiofur hydrochloride.Materials and Methods: A total of 610 dairy cows from 6 farms in Germany were enrolled. Inclusion criteria was a rectal temperature (RT ≥ 39.5 °C and a reddish-brown fetid vaginal discharge within the first 10 DIM. Cows meeting the inclusion criteria were randomly allocated to treatment with ketoprofen (3 mg/kg of body weight, n = 300 or treatment with ceftiofur (1 mg/kg of body weight, n = 310, both administered on 3 consecutive days. Rectal temperature was recorded daily for a period of 7 days after enrollment. Cows that showed RT ≥ 39.5 °C on day 4 to 7 after inclusion received an extended treatment (extT with ceftiofur for 3 (ketoprofen group or 2 (ceftiofur group more days. Between 21 and 40 DIM cows were examined with the metricheck device and vaginal discharge was categorized on a 5-point scale according to the presence of pus.Results: A total of 52 cows (35 from ketoprofen group, 17 from ceftiofur group were excluded from analysis due to missing protocol compliance (n = 37 or concurrent disease (n = 15. Cows initially treated with ketoprofen had higher odds of extT than cows treated with ceftiofur (61% vs 31%, OR 3.47, P < 0.01, n = 558. Occurrence of purulent vaginal discharge (PVD was similar for both treatment groups. However, cows with extT had 2.12 (P < 0.01, n = 438 times the odds of PVD than cows without extended treatment. Treatment group did not affect milk yield, first artificial insemination pregnancy risk, time to first AI and time to pregnancy.Conclusions: The results indicate that although cows initially treated with ketoprofen were more likely to receive extT, fewer doses of ceftiofur (1.83 were required compared with cows initially treated with ceftiofur (3.63. Consequently, there is considerable potential of reducing antimicrobial treatment by implementing a treatment protocol starting with ketoprofen.

The ratio of albumin / creatinine urine in patients with ax-SpA was 35,8 [25,46; 43,4] mg/g, in patients DDS —207,1 [91,66; 244,59] mg/g (p<0,0001, in healthy individuals —25,45 [17,34; 33,65] mg/g. Conclusions. Patients with chronic back pain taking NSAIDs for a long time have revealed GFR, comparable with healthy people, and increased urine albumin. Patients with degenerative diseases of the spine have a greater index of albumin in urine than patients with ax-SpA.

    We report a randomized trial examining adjunctive administration of the NSAID, tenoxicam, to divers suffering with DCI. 180 subjects were graded for severity on admission and randomized according to a stratified random number schedule. Subjects were recompressed and treatment continued daily until symptom stabilization or complete resolution. Tenoxicam 20 mg or a placebo preparation was administered at the first air break during the initial recompression and continued daily for seven days. The subjects were assessed using a recovery status score at the completion of treatment and at 4-6 weeks. The proportion of patients with mild residual symptoms at discharge and final follow-up was not significantly different (discharge placebo 30% versus tenoxicam 37%, P=0.41; six weeks placebo 20% versus tenoxicam 17%, P=0.58). There was a significant reduction in the number of treatments required to achieve discharge (median treatments placebo 3, tenoxicam 2, P=0.01). 61% of patients in the tenoxicam group required less than 3 compressions, versus 40% in the placebo group (P=0.01, RRR 33 % [95%CI 9%-56%], NNT=5 [95%CI 3-18]). There was no evidence of increased complications of treatment in the tenoxicam group. When given this NSAID, patients with DCI require fewer hyperbaric oxygen (HBO2) sessions to achieve a standard clinical end-point and there is likely to be an associated cost saving.

    Full Text Available The aim of the present study was to evaluate Allium ursinum leaves and flowers extract anti-inflammatory effect. Plant extract 1:1 (w:v was prepared from A. ursinum leaves by a modified Squibb repercolation method. The in vivo anti-inflammatory effects were evaluated on a rat turpentine oil-induced inflammation (i.m. 6 mL/kg BW. The animals were randomly assigned to nine groups (n=8: negative control, inflammation, A. ursinum flower extract (AUF, A. ursinum leaves extract (AUL, indomethacin (INDO (20 mg/kg BW, aminoguanidine (AG (50 mg/kg b.w./d i.p. as a selective NOS2 inhibitor, NG-nitro L-arginine methyl ester (NAME (5 mg/kg b.w./d i.p. as a nonselective NOS inhibitor, L-arginine (ARG (100 mg/kg b.w./d i.p., NO synthesis substrate, and Trolox (20 mg/kg b.w./d i.p as an antioxidant. At 24h from inflammation induction total oxidative status (TOS, oxidative stress index (OSI, nitric oxide (NOx and in vitro phagocytosis test were reduced and the total antioxidative reactivity (TAR was increased by the testes plant extracts. AUF had a better inhibitory effect than AUL. In conclusion, we provided evidence for the hypothesis that A. ursinum leaves and flowers extract exerts anti-inflammatory activity by inhibiting the phagocytosis through the reduction of the nitro-oxidative stress.

  6. N-Acetylcysteine enhances the action of anti-inflammatory drugs as suppressors of prostaglandin production in monocytes

    Directory of Open Access Journals (Sweden)

    Erica Hoffer

    2002-01-01

    Full Text Available The anti-inflammatory effect of non-steroidal anti-inflammatory drugs (NSAIDs is associated with inhibition of cyclooxygenase (COX, the rate-limiting enzyme responsible for the synthesis of prostaglandins. Since oxygen free radicals can act as second cellular messengers, especially to modulate the metabolism of arachidonic acid and the prostaglandin tract, it seems plausible that antioxidants might affect the production of prostaglandin by activated cells. This research is focused on the effect of the antioxidant N-acetylcysteine (NAC on the inhibition of prostaglandin E2 formation in activated monocytes by specific and non-specific COX inhibitors. We found that lipopolysaccharide-induced prostaglandin E2 formation was significantly reduced by rofecoxib and by diclofenac, two NSAIDs. Addition of NAC to each of these drugs enhanced the effect of the NSAIDs. These results suggest that one might expect either a potentiation of the anti-inflammatory effect of COX inhibitors by their simultaneous administration with NAC, or obtaining the same anti-inflammatory at lower drug levels.

  8. Anti-inflammatory drugs in the 21st century.

    Rainsford, K D

    2007-01-01

    Historically, anti-inflammatory drugs had their origins in the serendipitous discovery of certain plants and their extracts being applied for the relief of pain, fever and inflammation. When salicylates were discovered in the mid-19th century to be the active components of Willow Spp., this enabled these compounds to be synthesized and from this, acetyl-salicylic acid or Aspirin was developed. Likewise, the chemical advances of the 19th-20th centuries lead to development of the non-steroidal anti-inflammatory drugs (NSAIDs), most of which were initially organic acids, but later non-acidic compounds were discovered. There were two periods of NSAID drug discovery post-World War 2, the period up to the 1970's which was the pre-prostaglandin period and thereafter up to the latter part of the last century in which their effects on prostaglandin production formed part of the screening in the drug-discovery process. Those drugs developed up to the 1980-late 90's were largely discovered empirically following screening for anti-inflammatory, analgesic and antipyretic activities in laboratory animal models. Some were successfully developed that showed low incidence of gastro-intestinal (GI) side effects (the principal adverse reaction seen with NSAIDs) than seen with their predecessors (e.g. aspirin, indomethacin, phenylbutazone); the GI reactions being detected and screened out in animal assays. In the 1990's an important discovery was made from elegant molecular and cellular biological studies that there are two cyclo-oxygenase (COX) enzyme systems controlling the production of prostanoids [prostaglandins (PGs) and thromboxane (TxA2)]; COX-1 that produces PGs and TxA2 that regulate gastrointestinal, renal, vascular and other physiological functions, and COX-2 that regulates production of PGs involved in inflammation, pain and fever. The stage was set in the 1990's for the discovery and development of drugs to selectively control COX-2 and spare the COX-1 that is central to

  9. Anti-inflammatory Nanomedicine for Cardiovascular Disease

    Full Text Available Coronary artery disease, in the development of which inflammation mediated by innate immune cells plays a critical role, is one of the leading causes of death worldwide. The 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins are a widely used lipid-lowering drug that has lipid-independent vasculoprotective effects, such as improvement of endothelial dysfunction, antioxidant properties, and inhibitory effects on inflammation. Despite recent advances in lipid-lowering therapy, clinical trials of statins suggest that anti-inflammatory therapy beyond lipid-lowering therapy is indispensible to further reduce cardiovascular events. One possible therapeutic option to the residual risk is to directly intervene in the inflammatory process by utilizing a nanotechnology-based drug delivery system (nano-DDS. Various nano-sized materials are currently developed as DDS, including micelles, liposomes, polymeric nanoparticles, dendrimers, carbon nanotubes, and metallic nanoparticles. The application of nano-DDS to coronary artery disease is a feasible strategy since the inflammatory milieu enhances incorporation of nano-sized materials into mononuclear phagocytic system and permeability of target lesions, which confers nano-DDS on “passive-targeting” property. Recently, we have developed a polymeric nanoparticle-incorporating statin to maximize its anti-inflammatory property. This statin nanoparticle has been tested in various disease models, including plaque destabilization and rupture, myocardial ischemia-reperfusion injury, and ventricular remodeling after acute myocardial infarction, and its clinical application is in progress. In this review, we present current development of DDS and future perspective on the application of anti-inflammatory nanomedicine to treat life-threatening cardiovascular diseases.

    Lippia dulcis hexane and ethanol extracts were tested for its anti-inflammatory activity in several animal models. Hexane extract showed to be inactive, but the ethanol extract at doses of 400 mg/kg produced significant inhibition of carrageenan-induced paw oedema and reduced the weight of cotton pellet-induced granuloma, moreover, the topical application of 0.5 mg/ear of this extract inhibited the edema induced with TPA by 49.13%, an effect which is of less intensity than that produced by indomethacine at the same dose.

  11. Erdosteine: antitussive and anti-inflammatory effects.

    Science.gov (United States)

    Dal Negro, Roberto W

    2008-01-01

    Erdosteine is a multifactorial drug currently used in COPD for its rheologic activity on bronchial secretions and its positive effects on bacterial adhesiveness. Erdosteine produces an active metabolite (Met 1) which was shown to produce antioxidant effects during the respiratory burst of human PMNs, due to the presence of an SH group. The substantial antitussive effects of erdosteine were first documented in clinical trials even though mucolytic agents are regarded as not consistently effective in ameliorating cough in patients with bronchitis, although they may be of benefit to this population in other ways. Actually, a mucolytic drug could exert antitussive effects if it also affects mucus consistency and enhances ciliary function. In the last decade, data from several studies on animal models pointed to the possible antitussive and anti-inflammatory properties of erdosteine and an indirect anti-inflammatory mechanism of action was suggested. Recently, data from some controlled versus placebo studies documented the antioxidant properties of erdosteine in humans and in current smokers with COPD. The mechanism of action was described as related to erdosteine's ability to inhibit some inflammatory mediators and some pro-inflammatory cytokines that are specifically involved in oxidative stress. As oxidative stress is also presumed to impair beta-adrenoceptor function and contribute to airway obstruction, specific controlled studies recently investigated the effect of antioxidant intervention on short-term airway response to salbutamol in nonreversible COPD, according to a double-blind design versus placebo and NAC. Only erdosteine consistently restored a significant short-term reversibility in COPD subjects, previously unresponsive to beta(2) adrenergics. This peculiar activity of erdosteine (to our knowledge never previously assessed) proved related to the ROS scavenging activity (which actually proved equal to that of N), and its significant inhibiting effect on

    2013-04-01

    Silk sericin was found to suppress the production of pro-inflammatory cytokines, which are related to the inflammatory reaction. The objectives of this study were to investigate the anti-inflammatory effect of sericin in vivo using the carrageenan-induced rat edema model and changes in the histology of tissues. The effects of sericin on the expression of COX-2 and iNOS were also evaluated. Sericin solutions at 0.004-0.080 mg/mL were applied topically to the top of the hind paw and carrageenan (1.0 mg) was injected subcutaneously to the plantar surface of the right hind paw. Our results indicated that sericin significantly reduced the inflammation in rats' paw compared with the negative control (water and acetone) and its effect at 0.080 mg/mL was only slightly lower than that of 1.0% w/v indomethacin. Similar numbers of polymorphonuclear and macrophage cells were found in rats' tissue treated with indomethacin and sericin solution, while the numbers were significantly higher in their absence. The gene expression results by RT-PCR showed that the COX-2 and iNOS genes were down-regulated in samples treated with sericin in a dose dependent manner. These data indicated that the anti-inflammatory properties of sericin may be partly attributable to the suppression of the COX-2 enzyme and nitric oxide production.

    2014-09-01

    Full Text Available Nonsteroidal anti-inflammatory drugs (NSAIDs are used by millions of people worldwide to neutralize pain that is of different origin, as well as to treat fever and inflammation. However, NSAIDs misuse/overuse can induce many adverse effects and some potentially serious complications. The aim of the our study was to ascertain young people’s knowledge about non-steroidal anti-inflammatory drugs. The research tool was a questionnaire. This study was carried out among students of the Medical University in Lublin, and it involved 236 persons of an average age of 20 years. The questions were intended to assess the frequency of NSAIDs use and the general knowledge that is held with respect to them. The results of this work show that more than 77% of the respondents confirmed that they use NSAIDs. Our results revealed no statistical correlation between the place of living or origin and the use of this drug. Hence, it can be said that while young adults quite often use NSAIDs, their knowledge about the dangers associated with the use of NSAIDs is low. Therefore, it is necessary to more intensively disseminate knowledge on the potential adverse effects of NSAID utilization.

    Cissus gum has been employed as polymer with sodium alginate in the formulation of diclofenac microbeads and the in vivo mucoprotective properties of the polymer in anti-inflammatory therapy assessed in rats with carrageenan-induced paw edema in comparison to diclofenac powder and commercial diclofenac tablet. A full 2(3) factorial experimental design has been used to investigate the influence of concentration of cissus gum (X1); concentration of calcium acetate (X2) and stirring speed (X3) on properties of the microbeads. Optimized small discrete microbeads with size of 1.22±0.10 mm, entrapment efficiency of 84.6% and t80 of 15.2±3.5 h were obtained at ratio of cissus gum:alginate (1:1), low concentration of calcium acetate (5% w/v) and high stirring speed (400 rpm). In vivo studies showed that the ranking of percent inhibition of inflammation after 3h was diclofenac powder>commercial tablet=cissus>alginate. Histological damage score and parietal cell density were lower while crypt depth and mucosal width were significantly higher (pdiclofenac microbeads than those administered with diclofenac powder and commercial tablet, suggesting the mucoprotective property of the gum. Thus, cissus gum could be suitable as polymer in the formulation of non-steroidal anti-inflammatory drugs ensuring sustained release while reducing gastric side effects.

    2007-02-01

    Full Text Available Rheedia longifolia Planch et Triana belongs to the Clusiaceae family. This plant is widely distributed in Brazil, but its chemical and pharmacological properties have not yet been studied. We report here that leaves aqueous extract of R. longifolia (LAE shows analgesic and anti-inflammatory effects. Oral or intraperitoneal administration of this extract dose-dependently inhibited the abdominal constrictions induced by acetic acid in mice. The analgesic effect and the duration of action were similar to those observed with sodium diclofenac, a classical non-steroidal analgesic. In addition to the effect seen in the abdominal constriction model, LAE was also able to inhibit the hyperalgesia induced by lipopolysaccharide from gram-negative bacteria (LPS in rats. We also found that R. longifolia LAE inhibited an inflammatory reaction induced by LPS in the pleural cavity of mice. Acute toxicity was evaluated in mice treated with the extract for seven days with 50 mg/kg/day. Neither death, nor alterations in weight, blood leukocyte counts or hematocrit were noted. Our results suggest that aqueous extract from R. longifolia leaves has analgesic and anti-inflammatory activity with minimal toxicity and are therefore endowed with a potential for pharmacological control of pain and inflammation.

    Aspirin, one of the most widely used non-steroidal anti-inflammatory drugs, has extensively studied effects on the cardiovascular system. To reveal further pleiotropic, beneficial effects of aspirin on a number of pro- and anti-inflammatory microglial mechanisms, we performed morphometric and functional studies relating to phagocytosis, pro- and anti-inflammatory cytokine production (IL-1β, tumor necrosis factor-α (TNF-α) and IL-10, respectively) and analyzed the expression of a number of inflammation-related genes, including those related to the above functions, in pure microglial cells. We examined the effects of aspirin (0.1mM and 1mM) in unchallenged (control) and bacterial lipopolysaccharide (LPS)-challenged secondary microglial cultures. Aspirin affected microglial morphology and functions in a dose-dependent manner as it inhibited LPS-elicited microglial activation by promoting ramification and the inhibition of phagocytosis in both concentrations. Remarkably, aspirin strongly reduced the pro-inflammatory IL-1β and TNF-α production, while it increased the anti-inflammatory IL-10 level in LPS-challenged cells. Moreover, aspirin differentially regulated the expression of a number of inflammation-related genes as it downregulated such pro-inflammatory genes as Nos2, Kng1, IL1β, Ptgs2 or Ccr1, while it upregulated some anti-inflammatory genes such as IL10, Csf2, Cxcl1, Ccl5 or Tgfb1. Thus, the use of aspirin could be beneficial for the prophylaxis of certain neurodegenerative disorders as it effectively ameliorates inflammation in the brain. Copyright © 2017 Elsevier Inc.

  18. On radiation damage to normal tissues and its treatment. Pt. 2; Anti-inflammatory drugs

    1994-01-01

    In addition to transiently inhibiting cell cycle progression and sterilizing those cells capable of proliferation, irradiation disturbs the homeostasis effected by endogenous mediators of intercellular communication (humoral component of tissue response to radiation). Changes in the mediator levels may modulate radiation effects either by a assisting a return to normality (e.g., through a rise in H-type cell lineage-specific growth factors) or by aggravating the damage. The latter mode is illustrated with reports on changes in eicosanoid levels after irradiation and on results of empirical treatment of radiation injuries with anti-inflammatory drugs. Prodromal, acute and chronic effects of radiation are accompanied by excessive production of eicosanoids (prostaglandins, prostacyclin, thromboxanes and leukotrienes). These endogenous mediators of inflammatory reactions may be responsible for the vasodilatation, vasoconstriction, increased microvascular permeability, thrombosis and chemotaxis observed after radiation exposure. Glucocorticoids inhibit eicosanoid synthesis primarily by interfering with phospholipase A[sub 2] whilst non-steroidal anti-inflammatory drugs prevent prostaglandin/thromboxane synthesis by inhibiting cycloxygenase. When administered after irradiation on empirical grounds, drugs belonging to both groups tend to attenuate a range of prodomal, acute and chronic effects of radiation in man and animals. Taken together, these two sets of observations are highly suggestive of a contribution of humoral factors to the adverse responses of normal tissues and organs to radiation. A full account of radiation damage should therefore consist of complementary descriptions of cellular and humoral events. Further studies on anti-inflammatory drug treatment of radiation damage to normal organs are justified and desirable. (orig.).

    2016-07-01

    Chronic inflammation is linked with the generation and progression of various diseases such as cancer, diabetes and atherosclerosis, and anti-inflammatory drugs therefore have the potential to assist in the treatment of these conditions. Carica papaya is a tropical plant that is traditionally used in the treatment of various ailments including inflammatory conditions. A literature search was conducted by using the keywords "papaya", "anti-inflammatory and inflammation" and "immunomodulation and immune" along with cross-referencing. Both in vitro and in vivo investigation studies were included. This is a review of all studies published since 2000 on the anti-inflammatory activity of papaya extracts and their effects on various immune-inflammatory mediators. Studies on the anti-inflammatory activities of recognized phytochemicals present in papaya are also included. Although in vitro and in vivo studies have shown that papaya extracts and papaya-associated phytochemicals possess anti-inflammatory and immunomodulatory properties, clinical studies are lacking.

    Taraxacum officinale has been widely used as a folkloric medicine for the treatment of diverse diseases. The dried plant was extracted with 70% ethanol to generate its ethanol extract (TEE). For some experiments, ethyl acetate (EA), n-butanol (BuOH) and aqueous (Aq) fractions were prepared in succession from TEE. TEE showed a scavenging activity in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay, a diminishing effect on intracellular reactive oxygen species (ROS) level, and an anti-angiogenic activity in the chicken chorioallantoic (CAM) assay. In the carrageenan-induced air pouch model, TEE inhibited production of exudate, and significantly diminished nitric oxide (NO) and leukocyte levels in the exudate. It also possessed an inhibitory effect on acetic acid-induced vascular permeability and caused a dose-dependent inhibition on acetic acid-induced abdominal writhing in mice. Suppressive effects of TEE on the production of NO and expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in lipopolysaccharide (LPS)-stimulated macrophages were also assessed. Among the fractions, the n-butanol fraction (BuOH) was identified to be most effective in the CAM assay. Collectively, Taraxacum officinale contains anti-angiogenic, anti-inflammatory and anti-nociceptive activities through its inhibition of NO production and COX-2 expression and/or its antioxidative activity.

  18. Compensatory anti-inflammatory response syndrome.

    2009-01-01

    The concept of 'Compensatory anti-inflammatory response syndrome' (CARS) was proposed in 1997 by Roger Bone (1941-1997) to qualify the consequences of the counter-regulatory mechanisms initiated to limit the overzealous inflammatory process in patients with infectious (sepsis) or non-infectious systemic inflammatory response syndrome (SIRS). One major consequence of CARS is the modification of the immune status that could favour the enhanced susceptibility of intensive care patients to nosocomial infections. Indeed, most animal 'two-hit' models illustrate an enhanced sensitivity to infection after a first insult. However, this observation is highly dependent on the experimental procedure. Numerous functions of circulating leukocytes are altered in sepsis and SIRS patients, as well as in animal models of sepsis or SIRS. However, this is rather a reprogramming of circulating leukocytes, since there is not a global defect of the immune cells functions. Furthermore, within tissues, leukocytes are rather primed or activated than immunosuppressed. Thus, CARS may be considered as an adapted compartmentalized response with the aim to silence some acute proinflammatory genes, and to maintain the possible expression of certain genes involved in the anti-infectious process.

    Flavonoids, natural compounds widely distributed in the plant kingdom, are reported to affect the inflammatory process and to possess anti-inflammatory as well as immunomodulatory activity in-vitro and in-vivo. Since nitric oxide (NO) produced by inducible nitric oxide synthase (iNOS) is one of the inflammatory mediators, the effects of the ethanol/water (1:1) extract of the leaves of Apium graveolens var. dulce (celery) on iNOS expression and NO production in the J774.A1 macrophage cell line stimulated for 24 h with Escherichia coli lipopolysaccharide (LPS) were evaluated. The extract of A. graveolens var. dulce contained apiin as the major constituent (1.12%, w/w, of the extract). The extract and apiin showed significant inhibitory activity on nitrite (NO) production in-vitro (IC50 0.073 and 0.08 mg mL(-1) for the extract and apiin, respectively) and iNOS expression (IC50 0.095 and 0.049 mg mL(-1) for the extract and apiin, respectively) in LPS-activated J774.A1 cells. The croton-oil ear test on mice showed that the extract exerted anti-inflammatory activity in-vivo (ID50 730 microg cm(-2)), with a potency seven-times lower than that of indometacin (ID50 93 microg cm(-2)), the non-steroidal anti-inflammatory drug used as reference. Our results clearly indicated the inhibitory activity of the extract and apiin in-vitro on iNOS expression and nitrite production when added before LPS stimulation in the medium of J774.A1 cells. The anti-inflammatory properties of the extract demonstrated in-vivo might have been due to reduction of iNOS enzyme expression.

  2. Salivary gland derived peptides as a new class of anti-inflammatory agents: review of preclinical pharmacology of C-terminal peptides of SMR1 protein

    2010-09-01

    Full Text Available Abstract The limitations of steroidal and non steroidal anti-inflammatory drugs have prompted investigation into other biologically based therapeutics, and identification of immune selective anti-inflammatory agents of salivary origin. The traditional view of salivary glands as accessory digestive structures is changing as their importance as sources of systemically active immunoregulatory and anti-inflammatory factors is recognized. Salivary gland involvement in maintenance of whole body homeostasis is regulated by the nervous system and thus constitutes a "neuroendocrine axis". The potent anti-inflammatory activities, both in vivo and in vitro, of the tripeptide Phe-Glu-Gly (FEG are reviewed. FEG is a carboxyl terminal peptide of the prohormone SMR1 identified in the rat submandibular salivary gland, The D-isomeric form (feG mimics the activity of its L-isomer FEG. Macropharmacologically, feG attenuates the cardiovascular and inflammatory effects of endotoxemia and anaphylaxis, by inhibition of hypotension, leukocyte migration, vascular leak, and disruption of pulmonary function and intestinal motility. Mechanistically, feG affects activated inflammatory cells, especially neutrophils, by regulating integrins and inhibiting intracellular production of reactive oxygen species. Pharmacodynamically, feG is active at low doses (100 μg/kg and has a long (9-12 hour biological half life. As a therapeutic agent, feG shows promise in diseases characterized by over exuberant inflammatory responses such as systemic inflammatory response syndrome and other acute inflammatory diseases. Arthritis, sepsis, acute pancreatitis, asthma, acute respiratory inflammation, inflammatory bowel disease, and equine laminitis are potential targets for this promising therapeutic peptide. The term "Immune Selective Anti-Inflammatory Derivatives" (ImSAIDs is proposed for salivary-derived peptides to distinguish this class of agents from corticosteroids and nonsteroidal anti-inflammatory

  3. Anti-inflammatory glucocorticoids: changing concepts.

    2014-02-05

    Despite being the most effective anti-inflammatory treatment for chronic inflammatory diseases, the mechanisms by which glucocorticoids (corticosteroids) effect repression of inflammatory gene expression remain incompletely understood. Direct interaction of the glucocorticoid receptor (NR3C1) with inflammatory transcription factors to repress transcriptional activity, i.e. transrepression, represents one mechanism of action. However, transcriptional activation, or transactivation, by NR3C1 also represents an important mechanism of glucocorticoid action. Glucocorticoids rapidly and profoundly increase expression of multiple genes, many with properties consistent with the repression of inflammatory gene expression. For example: the dual specificity phosphatase, DUSP1, reduces activation of mitogen-activated protein kinases; glucocorticoid-induced leucine zipper (TSC22D3) represses nuclear factor-κB (NF-κB) and activator protein 1 (AP-1) transcriptional responses; inhibitor of κBα (NFKBIA) inhibits NF-κB; tristraprolin (ZFP36) destabilises and translationally represses inflammatory mRNAs; CDKN1C, a cell cycle regulator, may attenuate JUN N-terminal kinase signalling; and regulator of G-protein signalling 2 (RGS2), by reducing signalling from Gαq-linked G protein-coupled receptors (GPCRs), is bronchoprotective. While glucocorticoid-dependent transrepression can co-exist with transactivation, transactivation may account for the greatest level and most potent repression of inflammatory genes. Equally, NR3C1 transactivation is enhanced by β2-adrenoceptor agonists and may explain the enhanced clinical efficacy of β2-adrenoceptor/glucocorticoid combination therapies in asthma and chronic obstructive pulmonary disease. Finally, NR3C1 transactivation is reduced by inflammatory stimuli, including respiratory syncytial virus and human rhinovirus. This provides an explanation for glucocorticoid resistance. Continuing efforts to understand roles for glucocorticoid

    Green tea has been shown to have beneficial effects against a variety of diseases such as cancer, obesity, diabetes, cardiovascular disease, and neurodegenerative diseases. Through cellular, animal, and human experiments, green tea and its major component, epigallocatechin-3-gallate (EGCG) have been demonstrated to have anti-inflammatory effects. Our previous findings have indicated that green tea and EGCG suppress the gene and/or protein expression of inflammatory cytokines and inflammation-related enzymes. Using bibliographic databases, particularly PubMed (provided by the http://www.ncbi.nlm.nih.gov/pubmed, US National Library of Medicine, National Institutes of Health, United States), we examined the potential usefulness of green tea/EGCG for the prevention and treatment of inflammatory diseases in human clinical and epidemiological studies. We also reviewed results from cellular and animal experiments and proposed action mechanisms. Most of the results from the human studies indicated the beneficial effects of green tea and tea catechins against inflammatory diseases. The cellular and animal studies also provided evidence for the favorable effects of green tea/EGCG. These results are compatible with our previous findings and can be largely explained by a mechanism wherein green tea/EGCG acts as an antioxidant to scavenge reactive oxygen species, leading to attenuation of nuclear factor-κB activity. Since green tea and EGCG have multiple targets and act in a pleiotropic manner, we may consider their usage to improve the quality of life in patients with inflammatory disease. Green tea and EGCG have beneficial health effects and no severe adverse effects; however, care should be taken to avoid overdosage, which may induce deleterious effects including hepatic injury.

    An investigation of topical anti-inflammatory activity was undertaken on plants used in Central America traditional medicine. Four herbal drugs used in the folk medicine of Central America to treat inflammatory skin affections (Acacia cornigera bark, Byrsonima crassifolia bark, Sphagneticola trilobata leaves and Sweetia panamensis bark) were evaluated for their topical anti-inflammatory activity. Petroleum ether, chloroform and methanol extracts were obtained for herbal medicines and then extracts were tested on Croton oil-induced ear dermatitis model in mice. Almost all the extracts reduced the Croton oil-induced ear dermatitis in mice and the chloroform ones showed the highest activity, with ID(50) (dose giving 50% oedema inhibition) values ranging from 112 microg/cm(2) (Byrsonima crassifolia) to 183 microg/cm(2) (Sphagneticola trilobata). As reference, ID(50) of the non-steroidal anti-inflammatory drug indomethacin was 93 microg/cm(2). Lipophilic extracts from these species can be regarded as potential sources of anti-inflammatory principles.

    BACKGROUND: Based on circulating C-reactive protein (CRP) levels, some individuals develop slightly increased inflammation as they age. In elderly inflamed rats, the muscle response to protein feeding is impaired, whereas it can be maintained by treatment with non-steroidal anti-inflammatory drugs...... increase in systemic inflammation does not affect the basal myofibrillar FSR or the myofibrillar FSR responses, which suggests that elderly individuals with slightly increased inflammation can benefit from protein ingestion and resistance exercise to stimulate muscle protein anabolism.

    2010-09-01

    Anti-inflammatory properties of bioactive titanium metals prepared by anodic oxidation (AO-Ti) and alkali-heat (AH-Ti) treatments were studied by bacterial adhesion test and myeloperoxidase (MPO) activity assay methods. The bioactivities of the metals were also evaluated by apatite formation ability and osteoblasts culture experiments. Both metals could induce apatite formation and support osteoblasts proliferation. At the condition with normal incandescent light shine, both bioactive titanium metals had antibacterial adhesion properties compared with the titanium metal without treatment. The MPO activity assay proved that they both showed anti-inflammatory properties in vivo. The bioactive AO-Ti had better anti-inflammatory properties than the AH-Ti. It indicated that it is possible to optimize the anti-inflammatory properties of the bioactive titanium metals by different preparation methods. (c) 2010 Wiley Periodicals, Inc.

    Objective To evaluate the anti-inflammatory and analgesic activities of leaf extract of Melanthera scandens (M. scandens). Methods The crude leaf extract (39–111 mg/kg) of M. scandens was investigated for anti-inflammatory and analgesic activities using various experimental models. The anti-inflammatory activity was investigated using carragenin, egg-albumin induced oedema models, while acetic acid, formalin-induced paw licking and thermal-induced pain models were used to evaluate the antinociceptive property. Results The extract caused a significant (P<0.05 – 0.001) dose-dependent reduction of inflammation and pains induced by different agents used. Conclusions The leaf extract possesses anti-inflammatory and analgesic effects which may be mediated through the phytochemical constituents of the plant. PMID:23569885

    Compounds that combine metal-based drugs with covalently linked targeted organic agents have been shown, in some instances, to exhibit superior anticancer properties compared to the individual counterparts. Within this framework, we prepared a series of organometallic ruthenium(II)- and osmium(II)-p-cymene complexes modified with the nonsteroidal anti-inflammatory drugs (NSAIDs) indomethacin and diclofenac. The NSAIDs are attached to the organometallic moieties via monodentate (pyridine/phosphine) or bidentate (bipyridine) ligands, affording piano-stool Ru(II) and Os(II) arene complexes of general formula [M(η(6)-p-cymene)Cl2(N)], where N is a pyridine-based ligand, {2-(2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetoxy)ethyl-3-(pyridin-3-yl)propanoate} or {2-(2-(2-((2,6-dichlorophenyl)amino)phenyl)acetoxy)ethyl-3-(pyridin-3-yl)propanoate}, [M(η(6)-p-cymene)Cl2(P)], where P is a phosphine ligand, {2-(2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetoxy)ethyl-4-(diphenylphosphanyl)benzoate} or {2-(2-(2-((2,6-dichlorophenyl)amino)phenyl)acetoxy)ethyl-4-(diphenylphosphanyl)benzoate, and [M(η(6)-p-cymene)Cl(N,N')][Cl], where N,N' is a bipyridine-based ligand, (4'-methyl-[2,2'-bipyridin]-4-yl)methyl-2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetate), (4'-methyl-[2,2'-bipyridin]-4-yl)methyl-2-(2-((2,6-dichlorophenyl)amino)phenyl)acetate), (bis(2-(2-(1-(4-chlorobenzoyl)-5-methoxy-2-methyl-1H-indol-3-yl)acetoxy)ethyl)[2,2'-bipyridine]-5,5'-dicarboxylate), or (bis(2-(2-(2-((2,6-dichlorophenyl)amino)phenyl)acetoxy)ethyl)[2,2'-bipyridine]-5,5'-dicarboxylate). The antiproliferative properties of the complexes were assessed in human ovarian cancer cells (A2780 and A2780cisR, the latter being resistant to cisplatin) and nontumorigenic human embryonic kidney (HEK-293) cells. Some of the complexes are considerably more cytotoxic than the original drugs and also display significant cancer cell selectivity.

    Our previous studies revealed that silver nanoparticles (AgNPs) promoted wound healing in part through their anti-inflammatory actions. As recent reports also suggested anti-inflammatory effects of dendrimers, we therefore undertook this study using dendrimer as the delivery system for AgNP to explore any potential synergistic anti-inflammatory efficacy. Lipopolysaccharide (LPS) was added to cultured RAW264.7 and J774.1 cells to mimic in vitro inflammation condition, followed by the addition of either silver dendrimer nanocomposite (Ag-DNC), AgNPs, or dendrimer. The levels of inflammatory markers TNF-alpha and interleukin-6 were assessed using ELISA assay. Furthermore, in vivo effects such of Ag-DNC, AgNPs, or dendrimer were studied in a burn wound model in mice. Our results confirmed that both naked dendrimer and AgNPs had anti-inflammatory properties. In in vitro study, Ag-DNC was shown to have the best anti-inflammatory efficacy than AgNPs or dendrimer alone. In-vivo experiments also indicated that animals in the Ag-DNC group had the fastest healing time with the least inflammation. Our study would suggest that dendrimer could provide additional anti-inflammatory benefits and might be an excellent delivery system for silver nanoparticles for future clinical application.

    Inflammation may cause accumulation of fluid in the injured area, which may promote bacterial growth. Other reports disclosed that non-steroidal anti-inflammatory drugs may enhance progression of bacterial infection. This work describes synthesis of new series of 2,3'-bipyridine-5-carbonitriles as structural analogs of etoricoxib, linked at position-6 to variously substituted thio or oxo moieties. Biological screening results revealed that compounds 2b, 4b, 7e and 8 showed significant acute and chronic AI activities and broad spectrum of antimicrobial activity. In addition, similarity ensemble approach was applied to predict potential biological targets of the tested compounds. Then, pharmacophore modeling study was employed to determine the most important structural parameters controlling bioactivity. Moreover, title compounds showed physicochemical properties within those considered adequate for drug candidates. This study explored the potential of such series of compounds as structural leads for further modification to develop a new class of dual AI-antimicrobial agents.

    The objective of this study was to develop a novel elastic bilayer vesicle entrapped with the non-steroidal anti-inflammatory drug (NSAID), diclofenac diethylammonium (DCFD) for topical use. Eighteen bilayer vesicular formulations composing of DPPC or Tween 61 or Span 60 mixed with cholesterol (at 1:1, 3:7 and 1:1 molar ratios, respectively) and ethanol at 0-25% (v/v), by chloroform film method with sonication were developed. The elastic Tween 61 niosomes which gave no sedimentation, no layer separation, unchanged particle sizes (about 200 nm) were selected to entrap DCFD. The entrapment efficiency of the drug in the conventional and elastic Tween 61 niosomes was 65 and 93%, respectively. At least 87% of DCFD determined by HPLC remained in elastic Tween 61 niosomes when kept at 4, 27 and 45 degrees C for 3 months. The deformability index values of the elastic niosomes were 13.76 and 3.44 times higher than the conventional niosomes entrapped and not entrapped with the drug, respectively, indicating the higher flexibility of the elastic vesicle especially, when entrapped with the drug. Transdermal absorption through excised rat skin was performed by vertical Franz diffusion cell at 32+/-2 degrees C for 6h. Gel containing elastic niosomes exhibited fluxes of DCFD in the stratum corneum (SC), deeper skin layer (viable epidermis and dermis, VED) and receiver chamber at 191.27+/-9.52, 16.97+/-2.77 and 3.76+/-0.54 microg/(cm2 h), whereas the commercial emulgel, containing an equivalent DCFD, gave 60.84+/-13.63, 7.33+/-1.70 and 0.14+/-0.01 microg/(cm2 h), respectively. The in vivo anti-inflammatory activity was evaluated by ethyl phenylpropiolate (EPP)-induced rat ear edema (n=3). DCFD entrapped in the developed elastic niosomes and incorporated in gel gave the same ear edema inhibition percentages of 23.81% at 30 min, but 2 and 9 times more inhibition percentages at 45 and 60 min than the commercial emulgel, respectively. This result has not only demonstrated the

    Full Text Available Background: The Alzheimer’s Disease Anti-inflammatory Prevention Trial (ADAPT tested whether non-steroidal anti-inflammatory drugs (NSAIDs can prevent Alzheimer’s disease (AD. The results were null. We analyzed ADAPT data to examine if the effects of NSAIDs on AD risk differed depending upon APOE genotype or age as has been suggested by previous observational studies. Methods: ADAPT randomized 2,528 cognitively intact older adults to either celecoxib, naproxen sodium or placebo; 2,388 participants provided blood samples for APOE genotyping. Proportional hazards regression was used to estimate the effects of naproxen or celecoxib versus placebo on incident AD by age at enrollment and APOE genotype. Results: The proportion of subjects providing a biological sample did not differ between the treatment groups. In models of AD risk, none of the tests for 2-way interactions between either NSAID and age or APOE genotype were significant (p > 0.05. Conclusions: The data did not support the hypothesis that the association between NSAIDs and AD risk differed by age or APOE genotype.

    Full Text Available Background: Compared to steroids non-steroidal anti-inflammatory drugs offer comparable anti-inflammatory action without ocular side-effects. Aim: To compare the anti-inflammatory effect and effect on IOP (Goldmann of topical diclofenac 0.1% with dexamethasone 0.1% after strabismus surgery. Design: Prospective, randomized, double-blind, single-center, clinical trial. Materials and Methods: Forty-three cases of constant horizontal strabismus, qualifying for standard uniocular recession-resection surgery on two horizontal rectus muscles were randomized to either the dexamethasone or diclofenac group. They were excluded if they had previous ocular surgery, recently used anti-inflammatory drugs and had a neurological, systemic or an ocular inflammatory condition. In addition all received ciprofloxacin 0.3% four times daily. Assessment was done on the first postoperative day and at two and four weeks. The inflammatory characteristics graded from nil (0 to severe (3 were: discomfort, chemosis, injection, discharge and drop-intolerance. Their sum provided the total inflammatory score (TIS. Results: Dexamethasone group (n=21 was comparable in age, gender, preoperative IOP, strabismus, anesthesia administered and baseline IOP, to diclofenac (n=22. There were no significant differences in the inflammatory characteristics and TIS. The dexamethasone group had IOP significantly higher at two weeks (95% CI 0.17 to 3.25 and four weeks (95% CI 1.09 to 4.24 compared to diclofenac group and the net change of IOP at four weeks (95% CI 0.60 to 3.14. Compared to the baseline IOP. Conclusion: Topical diclofenac is comparable to dexamethasone in providing anti-inflammatory and analgesic effect with the advantage of significantly lesser IOP rise and should be preferred after strabismus surgery.

  3. Lyprinol—Is It a Useful Anti-Inflammatory Agent?

    Full Text Available The New Zealand green lipped mussel preparation Lyprinol is available without a prescription from a supermarket, pharmacy or Web. The Food and Drug Administration have recently warned Lyprinol USA about their extravagant anti-inflammatory claims for Lyprinol appearing on the web. These claims are put to thorough review. Lyprinol does have anti-inflammatory mechanisms, and has anti-inflammatory effects in some animal models of inflammation. Lyprinol may have benefits in dogs with arthritis. There are design problems with the clinical trials of Lyprinol in humans as an anti-inflammatory agent in osteoarthritis and rheumatoid arthritis, making it difficult to give a definite answer to how effective Lyprinol is in these conditions, but any benefit is small. Lyprinol also has a small benefit in atopic allergy. As anti-inflammatory agents, there is little to choose between Lyprinol and fish oil. No adverse effects have been reported with Lyprinol. Thus, although it is difficult to conclude whether Lyprinol does much good, it can be concluded that Lyprinol probably does no major harm.

    Full Text Available Objective: The objective of the study is to evaluate the acute and chronic anti-inflammatory activities of root extract of Alpinia galanga in rodents. Materials and Methods: The study was carried out using albino rats of either sex (150-200 g. An extract of the root of A. galanga was prepared using absolute alcohol and distillation in a Soxhlet apparatus. The acute anti-inflammatory effects of this extract were evaluated using carrageenan-, bradykinin-, and 5-HT-induced rat paw edema. The chronic anti-inflammatory effects were evaluated using formaldehyde-induced rat paw edema. Results and Analysis: Inhibition of inflammation was seen to be 32.22% in carrageenan-induced, 37.70% in 5-HT-induced, and 35.21% in bradykinin-induced anti-inflammatory models. In chronic inflammatory model, a progressive inhibition of 34.73% (3 rd day, 37.50% (5 th day, 38.83% (7 th day, 44.66% (9 th day, 49.59% (11 th day, and 55.75% (13 th day was observed with study compound. The efficacy was comparable with the standard drugs. Conclusion: It can be thus concluded that A. galanga has anti-inflammatory properties and probably acts by blocking histaminic and serotonin pathways. It may be an effective alternative to NASAIDs and corticosteroid in inflammatory disorders.

    Full Text Available The Chir Pine, Pinus roxburghii, named after William Roxburgh, is a pine native to the Himalaya. Pinus roxburghii Sarg. (Pinaceae is traditionally used for several medicinal purposes in India. As the oil of the plant is extensively used in number of herbal preparation for curing inflammatory disorders, the present study was undertaken to assess analgesic and anti-inflammatory activities of its bark extract. Dried and crushed leaves of Pinus roxburghii Sarg. were defatted with petroleum ether and then extracted with alcohol. The alcoholic extract at the doses of 100 mg/kg, 300 mg/kg, and 500 mg/kg body weight was subjected to evaluation of analgesic and anti-inflammatory activities in experimental animal models. Analgesic activity was evaluated by acetic acid-induced writhing and tail immersion tests in Swiss albino mice; acute and chronic anti-inflammatory activity was evaluated by carrageenan-induced paw oedema and cotton pellet granuloma in Wistar albino rats. Diclofenac sodium and indomethacin were employed as reference drugs for analgesic and anti-inflammatory studies, respectively. In the present study, the alcoholic bark extract of Pinus roxburghii Sarg. demonstrated significant analgesic and anti-inflammatory activities in the tested models.

    In this study, we evaluated the anti-inflammatory activity of the soluble ethyl acetate fraction and chemical components of the stem bark of Passiflora foetida (Passifloraceae). Ten flavonoids (1-10) were isolated by various chromatographic techniques, and their structures were determined based on spectroscopic analyses by using nuclear magnetic resonance (NMR). Luteolin (2) and chrysoeriol (3) showed the most potent inhibition of nitric oxide (NO) production in macrophage cell line, RAW264.7, with half maximal inhibitor concentration (IC50) values of 1.2 and 3.1 μM, respectively. These compounds suppressed lipopolysaccharide (LPS)-induced inducible NO synthase (iNOS) expression at the transcription level. Our research indicates that the stem bark of P. foetida has significant anti-inflammatory properties, suggesting that its flavonoids may have anti-inflammatory benefits.

    This report describes the isolation and characterization of kalanchosine dimalate (KMC), an anti-inflammatory salt from the fresh juice of the aerial parts of Kalanchoe brasiliensis. KMC comprises the new metabolite kalanchosine (1) and malic acid (2) in a 1:2 stoichiometric ratio. Kalanchosine (1), 3,6-diamino-4,5-dihydroxyoctanedioic acid, is the first naturally occurring dimeric bis(gamma-hydroxy-beta-amino acid) and is at least partially responsible for the anti-inflammatory properties of K. brasiliensis.

    An NAD(P)-dependent 3 alpha-hydroxysteroid dehydrogenase (EC 1.1.1.50) was purified to homogeneity from rat liver cytosol, where it is responsible for most if not all of the capacity for the oxidation of androsterone, 1-acenaphthenol and benzenedihydrodiol (trans-1,2-dihydroxycyclohexa-3,5-diene). The dehydrogenase has many properties (substrate specificity, pI, Mr, amino acid composition) in common with the dihydrodiol dehydrogenase (EC 1.3.1.20) purified from the same source [Vogel, Bentley, Platt & Oesch (1980) J. Biol. Chem. 255, 9621-9625]. Since 3 alpha-hydroxysteroids are by far the most efficient substrates, the enzyme is more appropriately designated a 3 alpha-hydroxysteroid dehydrogenase. It also promotes the NAD(P)H-dependent reductions of quinones (e.g. 9,10-phenanthrenequinone, 1,4-benzoquinone), aromatic aldehydes (4-nitrobenzaldehyde) and aromatic ketones (4-nitroacetophenone). The dehydrogenase is not inhibited by dicoumarol, disulfiram, hexobarbital or pyrazole. The mechanism of the powerful inhibition of this enzyme by both non-steroidal and steroidal anti-inflammatory drugs [Penning & Talalay (1983) Proc. Natl. Acad. Sci. U.S.A. 80, 4504-4508] was examined with several substrates. Most non-steroidal anti-inflammatory drugs are competitive inhibitors (e.g. Ki for indomethacin, 0.20 microM for 9,10-phenanthrenequinone reduction at pH 6.0, and 0.835 microM for androsterone oxidation at pH 7.0), except for salicylates, which act non-competitively (e.g. Ki for aspirin, 650 microM for androsterone oxidation). The inhibitory potency of these agents falls sharply as the pH is increased from 6 to 9. Most anti-inflammatory steroids are likewise competitive inhibitors, except for the most potent (betamethasone and dexamethasone), which act non-competitively. The enzyme is inhibited competitively by arachidonic acid and various prostaglandins. PMID:6435601

    Major depressive disorder (MDD) is a prevalent and disabling psychiatric disease with rates of non-responsiveness to antidepressants ranging from 30–50%. Historically, the monoamine depletion hypothesis has dominated the view on the pathophysiology of depression. However, the lack of responsiveness to antidepressants and treatment resistance suggests that additional mechanisms might play a role. Evidence has shown that a subgroup of depressive patients may have an underlying immune deregulation that could explain the lack of therapeutic benefit from antidepressants. Stimuli like inflammation and infection can trigger the activation of microglia to release pro-inflammatory cytokines, acting on two main pathways: (1) activation of the hypothalamic–pituitary adrenal axis, generating an imbalance in the serotonergic and noradrenergic circuits; (2) increased activity of the enzyme indoleamine-2,3-dioxygenase, resulting in depletion of serotonin levels and the production of quinolinic acid. If this hypothesis is proven true, the subgroup of MDD patients with increased levels of pro-inflammatory cytokines, mainly IL-6, TNF-α and IL-1β, might benefit from an anti-inflammatory intervention. Here, we discuss the pre-clinical and clinical studies that have provided support for treatment with non-steroidal anti-inflammatory drugs in depressed patients with inflammatory comorbidities or an elevated immune profile, as well as evidences for anti-inflammatory properties of standard antidepressants.

    Turmeric (rich in curcuminoids) and ginger (rich in gingerols and shogaols) rhizomes have been widely used as dietary spices and to treat different diseases in Ayurveda/Chinese medicine since antiquity. Here, we compared the anti-inflammatory/anti-oxidant activity of these two plants in rat adjuvant-induced arthritis (AIA). Both plants (at dose 200 mg/kg body weight) significantly suppressed (but with different degrees) the incidence and severity of arthritis by increasing/decreasing the production of anti-inflammatory/pro-inflammatory cytokines, respectively, and activating the anti-oxidant defence system. The anti-arthritic activity of turmeric exceeded that of ginger and indomethacin (a non-steroidal anti-inflammatory drug), especially when the treatment started from the day of arthritis induction. The percentage of disease recovery was 4.6-8.3% and 10.2% more in turmeric compared with ginger and indomethacin (P turmeric over ginger and indomethacin, which may have beneficial effects against rheumatoid arthritis onset/progression as shown in AIA rat model.

    This thesis deals with the electrophilic substitution radioiodination reaction of non-steroidal anti-inflammatory drugs namely, Piroxicam (Pirox), Meloxicam (Melox), Etodolac and Naproxen for using them as anti-inflammatory imaging agent. The factors affecting the percent of radiochemical yields such as drug concentration, ph of the reaction mixtures, different oxidizing agents, reaction time, temperature and different organic media were studied. We can divide the objective of this thesis into three parts: First part performs to compare the electrophilic substitution radioiodination reaction of Piroxicam (Pirox) and Meloxicam (Melox) with Iodine-125 where both chloramine-T (CAT) and iodogen were used as oxidizing agents. The maximum radiochemical yield of 125 I-Piroxicam ( 125 I-Pirox) was (94%) using 3.7 MBq of Na 125 I, 0.4 mM of Pirox as substrate, 3.6 mM of chloramine-T (CAT) as oxidizing agent in acetone at neutral ph=7 at 60 degree C within 20 min where the maximum radiochemical yield of ( 125 I-Melox) was (92%) using 0.7 mM of Melox as substrate, 0.62 mM of iodogen as oxidizing agent in acetone at neutral ph=7 at 25 degree C within 30 min. The radiochemical yields were determined by TLC using methylene chloride: ethyl acetate (3: 7 v/v) as a developing system and by high-pressure liquid chromatography (HPLC) using reversed phase RP-18 column and methanol: water (70: 30 v/v) as mobile phase at flow rate (1 ml/min). Tracers showed good localization in inflamed muscle either (septic or sterile). The collected data indicates that Pirox can be used as anti-inflammatory imaging agent at 24 h post injection however Melox can be used as anti-inflammatory imaging agent at 2 h due to its shorter biological half life (t 1/2 ) compared with Pirox. Second part describes a fast and efficient method for radiolabeling of etodolac with iodine-125, where both chloramine-T and iodogen were used as oxidizing agents. The labeling reaction was carried out via electrophilic

    With the observation that cupric acetate had anti-inflammatory activity in the foot edema model of inflammation, it was felt that copper may play a role as a component of the active metabolite of anti-inflammatory agents used clinically. To test this hypothesis, various Cu chelates were made and tested in the foot edema, cotton-wad granuloma and polyarthritis models of inflammation. A marked increase in anti-inflammatory activity has been observed for the Cu chelates of chelating agents that had no anti-inflammatory activity as well as those that have been used clinically. Since ulcers may be viewed as inflammatory processes and often associated with the arthritic disease syndrome, the Cu chelates were evaluated as anti-ulcer agents. These compounds were demonstrated to have anti-ulcer activity in the Shay as well as the corticoid and stress induced rat ulcer models. Mechanistic considerations relevant to lysosomal and digestive proteolytic enzyme inhibition, anti-cholinergic activity, prostaglandin synthesis and wound healing are discussed. 9 references, 3 figures, 3 tables.

    Heparin, a glycosaminoglycan (GAG), has both anti-inflammatory and anti-coagulant properties. The clinical use of heparin against inflammation, however, has been limited by concerns about increased bleeding. While the anti-coagulant activity of heparin is well understood, its anti-inflammatory properties are less so. Heparin is known to bind to certain cytokines, including chemokines, small proteins which mediate inflammation through their control of leukocyte migration and activation. Molecules which can interrupt the chemokine-GAG interaction without inhibiting coagulation could therefore, represent a new class of anti-inflammatory agents. In the present study, two approaches were undertaken, both focusing on the heparin-chemokine relationship. In the first, a structure based strategy was used: after an initial screening of potential small molecule binders using protein NMR on a target chemokine, binding molecules were optimized through structure-based design. In the second approach, commercially available short oligosaccharides were polysulfated. In vitro, these molecules prevented chemokine-GAG binding and chemokine receptor activation without disrupting coagulation. However, in vivo, these compounds caused variable results in a murine peritoneal recruitment assay, with a general increase of cell recruitment. In more disease specific models, such as antigen-induced arthritis and delayed-type hypersensitivity, an overall decrease in inflammation was noted, suggesting that the primary anti-inflammatory effect may also involve factors beyond the chemokine system.

    Medicinal mushrooms have been essential components of traditional Chinese herbal medicines for thousands of years, and they protect against diverse health-related conditions. The components responsible for their anti-inflammatory activity have yet to be fully studied. This study investigates the anti-inflammatory activity of n-hexane, chloroform, ethyl acetate, and methanol extracts of mycelia in submerged culture from 5 commercially available medicinal mushrooms, namely Cephalosporium sinensis, Cordyceps mortierella, Hericium erinaceus, Ganoderma lucidum, and Armillaria mellea. MTT colorimetric assay was applied to measure the cytotoxic effects of different extracts. Their anti-inflammatory activities were evaluated via inhibition against production of lipopolysaccharide (LPS)-induced nitric oxide (NO) in murine macrophage-like cell line RAW264.7 cells. Of the 20 extracts, n-hexane, chloroform, ethyl acetate, and methanol extracts from C. sinensis, C. mortierella, and G. lucidum; chloroform extracts from H. erinaceus and A. mellea; and ethyl acetate extracts from A. mellea at nontoxic concentrations (effective inhibitor, with the lowest half maximal inhibitory concentration (64.09 ± 6.29 μg/mL) of the LPS-induced NO production. These results indicate that extracts from medicinal mushrooms exhibited anti-inflammatory activity that might be attributable to the inhibition of NO generation and can therefore be considered a useful therapeutic and preventive approach to various inflammation-related diseases.

    González, Yisett; Torres-Mendoza, Daniel; Jones, Gillian E.; Fernandez, Patricia L.

    2015-01-01

    The inflammatory response is a highly regulated process, and its dysregulation can lead to the establishment of chronic inflammation and, in some cases, to death. Inflammation is the cause of several diseases, including rheumatoid arthritis, inflammatory bowel diseases, multiple sclerosis, and asthma. The search for agents inhibiting inflammation is a great challenge as the inflammatory response plays an important role in the defense of the host to infections. Marine invertebrates are exceptional sources of new natural products, and among those diterpenoids secondary metabolites exhibit notable anti-inflammatory properties. Novel anti-inflammatory diterpenoids, exclusively produced by marine organisms, have been identified and synthetic molecules based on those structures have been obtained. The anti-inflammatory activity of marine diterpenoids has been attributed to the inhibition of Nuclear Factor-κB activation and to the modulation of arachidonic acid metabolism. However, more research is necessary to describe the mechanisms of action of these secondary metabolites. This review is a compilation of marine diterpenoids, mainly isolated from corals, which have been described as potential anti-inflammatory molecules. PMID:26538822
