Andrographis paniculata Nees (Acanthacae) is commonly used medicinal plant in the traditional. Unani and Ayurvedic medicinal systems. It has broad range of pharmacological effects such as hepatoprotective, antioxidant, antivenom, antifertility, inhibition of replication of the HIV virus, antimalarial, antifungal, antibacterial, antidiabetic, suppression of various cancer cells and anti-inflammatory properties. Andrographolide (AN) is one of the active constituent of the A. paniculata Nees extract (APE). They have been found in many traditional herbal formulations in India and proven to be effective as anti-inflammatory drug To evaluate the pharmacokinetic and pharmacodynamic (anti-arthritic) herb-drug interactions of A. paniculata Nees extract (APE) and pure andrographolide (AN) with etoricoxib (ETO) after oral co-administration in wistar rats. After oral co-administration of APE (200mg/Kg) and AN (60mg/kg) with ETO (10mg/kg) in rats, drug concentrations in plasma were determined using HPLC method. The main pharmacokinetic parameters of Cmax, tmax, t1/2, MRT, Vd, CL, and AUC were calculated by non-compartment model. Change in paw volume, mechanical nociceptive threshold, mechanical hyperalgesia, histopathology and hematological parameters were evaluated to study antiarthritic activity. Co-administration of ETO with APE and pure AN decreased systemic exposure level of each compound in vivo. The Cmax, AUC, t1/2 of ETO was decreased whereas Vd and CL of ETO was increased significantly after co-administration of ETO with pure AN and APE. In pharmacodynamic study, ETO alone and ETO+APE (10+200mg/kg) groups exhibited significant synergistic anti-arthritic activity as compared to groups ETO+AN, APE and AN alone. The results obtained from this study suggested that ETO, APE and pure AN existed pharmacokinetic herb-drug interactions in rat which is correlated with anti-arthritic study. Physicians and patients using A. paniculata should have the knowledge about its possible

Drug histories were obtained from 76 patients at the time of initial Eder-Puestow dilatation for benign oesophageal stricture. Six patients had consumed drugs known to cause oesophageal ulceration (emepronium bromide and potassium preparations). Of the remaining 70 patients, 22 had regularly taken a non-steroidal anti-inflammatory drug before the onset of dysphagia compared with 10 patients in a control group matched for age and sex; this difference was significant (p less than 0.02). Non-steroidal anti-inflammatory drugs may have a causative role in the formation of oesophageal stricture in patients with gastro-oesophageal reflux, in whom they should be prescribed with caution.

Knowles, Richard Graham

2014-01-01

The research and development process for novel drugs to treat inflammatory diseases is described, and several current issues and debates relevant to this are raised: the decline in productivity, attrition, challenges and trends in developing anti-inflammatory drugs, the poor clinical predictivity of experimental models of inflammatory diseases, heterogeneity within inflammatory diseases, 'improving on the Beatles' in treating inflammation, and the relationships between big pharma and biotechs. The pharmaceutical research and development community is responding to these challenges in multiple ways which it is hoped will lead to the discovery and development of a new generation of anti-inflammatory medicines. © 2013 Nordic Pharmacological Society.

Full Text Available Steven P Stanos Rehabilitation Institute of Chicago, Center for Pain Management, Chicago, IL, USA Abstract: Current treatment guidelines for the treatment of chronic pain associated with osteoarthritis reflect the collective clinical knowledge of international experts in weighing the benefits of pharmacologic therapy options while striving to minimize the negative effects associated with them. Consideration of disease progression, pattern of flares, level of functional impairment or disability, response to treatment, coexisting conditions such as cardiovascular disease or gastrointestinal disorders, and concomitant prescription medication use should be considered when creating a therapeutic plan for a patient with osteoarthritis. Although topical nonsteroidal anti-inflammatory drugs historically have not been prevalent in many of the guidelines for osteoarthritis treatment, recent evidence-based medicine and new guidelines now support their use as a viable option for the clinician seeking alternatives to typical oral formulations. This article provides a qualitative review of these treatment guidelines and the emerging role of topical nonsteroidal anti-inflammatory drugs as a therapy option for patients with localized symptoms of osteoarthritis who may be at risk for oral nonsteroidal anti-inflammatory drug-related serious adverse events.

Macrolides, polyketide natural products, and their 15-membered semi-synthetic derivatives are composed of substituted macrocyclic lactone ring and used primarily as potent antibiotics. Recently their usefulness was extended to antimalarial and anti-inflammatory area. Hybrid macrolides presented in this article are the next generation semi-synthetic compounds that combine pharmacophores from antibacterial, antimalarial and anti-inflammatory area with 14- and 15-membered azalide scaffolds. Antibacterial azalide hybrids with sulphonamides showed improved activity against resistant streptococci while quinolone conjugates demonstrated full coverage of respiratory pathogens including macrolide resistant strains and their efficacy was confirmed in mouse pneumonia model. Antimalarial macrolide hybrids, mainly involving (chloro)quinoline pharmacophores, showed outstanding activity against chloroquine resistant strains, favourable pharmacokinetics, promising in vivo efficacy as well as encouraging developmental potential. Anti-inflammatory hybrids were obtained by combining macrolides with corticosteroid and non-steroidal anti-inflammatory drugs. They were found active in in vivo animal models of locally induced inflammation, asthma, inflammatory bowel disease and rheumatoid arthritis and demonstrated improved safety over parent steroid drugs. Overall, macrolide hybrids possess significant potential to be developed as potent novel medicines in therapeutic areas of utmost pharmaceutical interest.

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.

Anti-inflammatory drugs in the 21st century.

Science.gov (United States)

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

Use of non-steroidal anti-inflammatory drugs that elevate cardiovascular risk: an examination of sales and essential medicines lists in low-, middle-, and high-income countries.

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 associations between Parkinson disease (PD) and putatively protective factors-smoking, caffeine (coffee, tea, and soft drinks), and nonsteroidal anti-inflammatory drugs (aspirin, ibuprofen, and naproxen). Family-based case-control study. Academic medical center clinic. A total of 356 case subjects and 317 family controls who self-reported environmental exposures. Associations between PD and environmental measures (history, status, dosage, duration, and intensity) of smoking, coffee, caffeine, nonsteroidal anti-inflammatory drugs, and non-aspirin nonsteroidal anti-inflammatory drugs were examined using generalized estimating equations with an independent correlation matrix while controlling for age and sex. Individuals with PD were significantly less likely to report ever smoking (odds ratio = 0.56; 95% confidence interval, 0.41-0.78). Additional measures of smoking revealed significant inverse associations with PD (Pcoffee drinking was inversely associated with PD (test for trend P = .05). Increasing dosage (trend P = .009) and intensity (trend P = .01) of total caffeine consumption were also inversely associated, with high dosage presenting a significant inverse association for PD (odds ratio = 0.58; 95% confidence interval, 0.34-0.99). There were no significant associations between nonsteroidal anti-inflammatory drugs and PD. Inverse associations of smoking and caffeine were corroborated using families with PD, thus emphasizing smoking and caffeine as important covariates to consider in genetic studies of PD.

Full Text Available Ischemia-reperfusion (I/R damage is known to be a pathological process which continues with the increase of oxidants and expands with the inflammatory response. There is not any study about protective effect of etoricoxib on the liver I/R damage in literature. Objective. This study investigates the effect of etoricoxib on oxidative stress induced by I/R of the rat liver. Material and Methods. Experimental animals were divided into four groups as liver I/R control (LIRC, 50 mg/kg etoricoxib + liver I/R (ETO-50, 100 mg/kg etoricoxib + liver I/R (ETO-100, and healthy group (HG. ETO-50 and ETO-100 groups were administered etoricoxib, while LIRC and HG groups were orally given distilled water by gavage. Hepatic artery was clamped for one hour to provide ischemia, and then reperfusion was provided for 6 hours. Oxidant, antioxidant, and COX-2 gene expressions were studied in the liver tissues. ALT and AST were measured. Results. Etoricoxib in 50 and 100 mg/kg doses changed the levels of oxidant/antioxidant parameters such as MDA, MPO, tGSH, GSHRd, GST, SOD, NO, and 8-OH/Gua in favour of antioxidants. Furthermore, etoricoxib prevented increase of COX-2 gene expression and ALT and AST levels. This important protective effect of etoricoxib on the rat liver I/R can be tested in the clinical setting.

9,10-Dimethyl benz(a)anthracene (DMBA), when injected intratracheally once at a dose of 20 mg/kg body weight, is found to induce lung cancer in rats. Two nonsteroidal anti-inflammatory drugs (NSAIDs), indomethacin and etoricoxib, are given orally daily as chemopreventive agents at a dose of 0.6 mg/kg body weight and 2 mg/kg body weight, respectively, along with DMBA. Morphologic and histologic analysis revealed the occurence of tumors and intense cellular proliferation in the DMBA-treated animals, whereas no such features were observed in the other groups. Nuclear factor κB, a nuclear transcription factor, and proliferating cell nuclear antigen, a cell proliferation antigen, were studied by immunoblotting and immunohistochemistry and their levels were markedly elevated in the DMBA group compared with the others. Oxidative stress parameters, as studied by the inducible nitric oxide synthase activity, and the levels of reactive oxygen and nitrogen species were found to be suppressed in the DMBA group. Furthermore, fluorescent staining of the isolated lung cells from bronchoalveolar lavage was performed to study apoptosis and alterations in the mitochondrial membrane potential, and the DMBA-induced lung cancer was found to be associated with high inner mitochondrial membrane potential and a suppressed level of apoptosis.

Anti-inflammatory drugs for Duchenne muscular dystrophy: focus on skeletal muscle-releasing factors.

2016-01-01

Duchenne muscular dystrophy (DMD), an incurable and a progressive muscle wasting disease, is caused by the absence of dystrophin protein, leading to recurrent muscle fiber damage during contraction. The inflammatory response to fiber damage is a compelling candidate mechanism for disease exacerbation. The only established pharmacological treatment for DMD is corticosteroids to suppress muscle inflammation, however this treatment is limited by its insufficient therapeutic efficacy and considerable side effects. Recent reports show the therapeutic potential of inhibiting or enhancing pro- or anti-inflammatory factors released from DMD skeletal muscles, resulting in significant recovery from muscle atrophy and dysfunction. We discuss and review the recent findings of DMD inflammation and opportunities for drug development targeting specific releasing factors from skeletal muscles. It has been speculated that nonsteroidal anti-inflammatory drugs targeting specific inflammatory factors are more effective and have less side effects for DMD compared with steroidal drugs. For example, calcium channels, reactive oxygen species, and nuclear factor-κB signaling factors are the most promising targets as master regulators of inflammatory response in DMD skeletal muscles. If they are combined with an oligonucleotide-based exon skipping therapy to restore dystrophin expression, the anti-inflammatory drug therapies may address the present therapeutic limitation of low efficiency for DMD.

However, their use has unravelled the important protective role of COX-2 for the cardiovascular (CV system, mainly through the generation of prostacyclin. In a recent nested-case control study, we found that patients taking NSAIDs (both coxibs and tNSAIDs had a 35% increase risk of myocardial infarction. The increased incidence of thrombotic events associated with profound inhibition of COX-2-dependent prostacyclin by coxibs and tNSAIDs can be mitigated, even if not obliterated, by a complete suppression of platelet COX-1 activity. However, most tNSAIDs and coxibs are functional COX-2 selective for the platelet (ie, they cause a profound suppression of COX-2 associated with insufficient inhibition of platelet COX-1 to translate into inhibition of platelet function, which explains their shared CV toxicity. The development of genetic and biochemical markers will help to identify the responders to NSAIDs or who are uniquely susceptible at developing thrombotic or GI events by COX inhibition. We will describe possible strategies to reduce the side effects of etoricoxib by using biochemical markers of COX inhibition, such as whole blood COX-2 and the assessment of prostacyclin biosynthesis in vivo.Keywords: etoricoxib, nonsteroidal antiinflammatory drugs, COX-2, gastrointestinal toxicity, cardiovascular toxicity, prostacyclin

Retrospective study. To determine whether low-dose tramadol plus non-steroidal anti-inflammatory drug combination therapy could prevent the transition of acute low back pain to chronic low back pain. Inadequately treated early low back pain transitions to chronic low back pain occur in approximately 30% of affected individuals. The administration of non-steroidal anti-inflammatory drugs is effective for treatment of low back pain in the early stages. However, the treatment of low back pain that is resistant to non-steroidal anti-inflammatory drugs is challenging. Patients who presented with acute low back pain at our hospital were considered for inclusion in this study. After the diagnosis of acute low back pain, non-steroidal anti-inflammatory drug administration was started. Forty patients with a visual analog scale score of >5 for low back pain 1 month after treatment were finally enrolled. The first 20 patients were included in a non-steroidal anti-inflammatory drug group, and they continued non-steroidal anti-inflammatory drug therapy for 1 month. The next 20 patients were included in a combination group, and they received low-dose tramadol plus non-steroidal anti-inflammatory drug combination therapy for 1 month. The incidence of adverse events and the improvement in the visual analog scale score at 2 months after the start of treatment were analyzed. No adverse events were observed in the non-steroidal anti-inflammatory drug group. In the combination group, administration was discontinued in 2 patients (10%) due to adverse events immediately following the start of tramadol administration. At 2 months, the improvement in the visual analog scale score was greater in the combination group than in the non-steroidal anti-inflammatory drug group (ppain to chronic low back pain.

The non-steroidal anti-inflammatory drugs (NSAIDs) are the most widely used pharmaceuticals worldwide. Interestingly, many of them have significant anticancer properties too. However, the poor water solubility of certain NSAIDs limits their application for cancer treatment. Nanosizing of such drugs can help to improve the solubility and this may result in enhanced anticancer activities too. Moreover, over dosages and the accompanying side effects of NSAIDs can be minimized by improving their solubility and bioavailability. Successful nanoformulation of three NSAIDs: ibuprofen (IBP), ketoprufen (KP) and naproxen (NAP) using a novel evaporation assisted solvent-antisolvent interaction (EASAI) method is reported here. Three water soluble and biocompatible polymers: polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA) and hydroxypropyl methylcellulose (HPMC) were used to stabilize the drug nanoparticles. Particles having spherical morphology with average size below 30 nm were thoroughly characterized using dynamic light scattering and field emission scanning electron microscopy (FESEM) imaging. The nanoformulation resulted in ten to fifteen fold improvements in the solubility and significant enhancement in the in-vitro drug release profiles of the NSAIDs.

The non-steroidal anti-inflammatory drugs (NSAIDs) are the most widely used pharmaceuticals worldwide. Interestingly, many of them have significant anticancer properties too. However, the poor water solubility of certain NSAIDs limits their application for cancer treatment. Nanosizing of such drugs can help to improve the solubility and this may result in enhanced anticancer activities too. Moreover, over dosages and the accompanying side effects of NSAIDs can be minimized by improving their solubility and bioavailability. Successful nanoformulation of three NSAIDs: ibuprofen (IBP), ketoprufen (KP) and naproxen (NAP) using a novel evaporation assisted solvent-antisolvent interaction (EASAI) method is reported here. Three water soluble and biocompatible polymers: polyvinylpyrrolidone (PVP), polyvinyl alcohol (PVA) and hydroxypropyl methylcellulose (HPMC) were used to stabilize the drug nanoparticles. Particles having spherical morphology with average size below 30 nm were thoroughly characterized using dynamic light scattering and field emission scanning electron microscopy (FESEM) imaging. The nanoformulation resulted in ten to fifteen fold improvements in the solubility and significant enhancement in the in-vitro drug release profiles of the NSAIDs. Anticancer screening of the nanoformulated NSAIDs against five different cancer cell lines such as MCF-7 (Human breast cancer cell line), (Human pancreatic cancer cell line) MIA-PA-CA-2, (Human colon cancer cell line) HT-29, (Human leukemia cell line) Jurkat and (human ovarian carcinoma cell line) A2780 was performed.

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.

Full Text Available 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.

The topical application of two different anti-inflammatory extracts incorporated in adhesive transdermal drug delivery systems (TDDSs) was investigated. Therefore, anti-inflammatory properties and percutaneous absorption behavior of adhesive TDDSs were characterized in vitro conducting experiments with a dermatologically relevant human skin model. Anti-inflammatory efficacy against UV irradiation of both TDDSs was determined in vitro with EpiDerm™. The reduction of the release of proinflammatory cytokines by topically applied TDDSs was compared with the reduction during the presence of the specific cyclooxygenase inhibitor diclofenac in the culture medium. A similar anti-inflammatory efficacy of the topically applied TDDSs in comparison with the use of diclofenac in the culture medium should be achieved. Furthermore, percutaneous absorption in efficacy tests was compared with percutaneous absorption in diffusion studies with porcine cadaver skin. Both the topically applied TDDSs showed a significant anti-inflammatory activity. Permeation coefficients through the stratum corneum and the epidermis gained from the release studies on porcine cadaver skin (Magnolia: 2.23·10(-5) cm/h, licorice: 4.68·10(-6) cm/h) were approximately five times lower than the permeation coefficients obtained with the EpiDerm™ skin model (Magnolia: 9.48·10(-5) cm/h, licorice: 24.0·10(-6) cm/h). Therefore, an adjustment of drug doses during experiments with the EpiDerm™ skin model because of weaker skin barrier properties should be considered.

Amides of non-steroidal anti-inflammatory drugs with thiomorpholine can yield hypolipidemic agents with improved anti-inflammatory activity.

2016-02-01

Novel amides of non steroidal anti-inflammatory drugs (NSAIDs), α-lipoic acid and indole-3-acetic acid with thiomorpholine were synthesised by a simple method and at high yields (60-92%). All the NSAID derivatives highly decreased lipidemic indices in the plasma of Triton treated hyperlipidemic rats. The most potent compound was the indomethacin derivative, which decreased total cholesterol, triglycerides and LDL cholesterol by 73%, 80% and 83%, respectively. They reduced acute inflammation equally or more than most parent acids. Hence, it could be concluded that amides of common NSAIDs with thiomorpholine acquire considerable hypolipidemic potency, while they preserve or augment their anti-inflammatory activity, thus addressing significant risk factors for atherogenesis.

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.

A gastroenterologist and arheumatologist answer the questions on the use ofnon-steroidal anti-inflammatory drugs raised by primary care physicians

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

Poor blood-brain barrier penetration of non-steroidal anti-inflammatory drugs (NSAIDs) has been blamed for the failure of the selective amyloid lowering agent (SALA) R-flurbiprofen in phase 3 clinical trials for Alzheimer’s disease (AD). NO-donor NSAIDs (NO-NSAIDs) provide an alternative, gastric-sparing approach to NSAID SALAs, which may improve bioavailability. NSAID analogs were studied for anti-inflammatory activity and for SALA activity in N2a neuronal cells transfected with human amyloid precursor protein (APP). Flurbiprofen (1) analogs were obtained with enhanced anti-inflammatory and anti-amyloidogenic properties compared to 1, however, esterification led to elevated Aβ1–42 levels. Hybrid nitrate prodrugs possessed superior anti-inflammatory activity and reduced toxicity relative to the parent NSAIDs, including clinical candidate, CHF5074. Although hybrid nitrates elevated Aβ1–42 at higher concentration, SALA activity was observed at low concentrations (≤ 1 µM): both Aβ1–42 and the ratio of Aβ1–42/Aβ1–40 were lowered. This biphasic SALA activity was attributed to the intact nitrate drug. For several compounds the selective modulation of amyloidogenesis was tested using an immunoprecipitation MALDI-TOF approach. These data support the development of NO-NSAIDs as an alternative approach towards a clinically useful SALA. PMID:21405086

Standard treatment for inflammatory bowel diseases (IBD) necessitates frequent intake of anti-inflammatory and/or immunosuppressive drugs, leading to significant adverse events. To evaluate the role solid lipid nanoparticles (SLN) play as drug delivery system in enhancing anti-inflammatory activity for drugs such as dexamethasone and butyrate in a human inflammatory bowel diseases whole-blood model. ELISA assay and the peripheral blood mononuclear cell (PBMC) cytokine mRNA expression levels were evaluated by quantitative SYBR Green real-time RT-PCR to determine the IL-1beta, TNF-alpha, IFN-gamma and IL-10 secretion in inflammatory bowel diseases patients' PBMC culture supernatants. There was a significant decrease in IL-1beta (p<0.01) and TNF-alpha (p<0.001) secretion, whilst IL-10 (p<0.05) secretion significantly increased after cholesteryl butyrate administration, compared to that of butyrate alone at the highest concentration tested (100 microM), at 24h exposure. There was a significant decrease in IL-1beta (p<0.01), TNF-alpha (p<0.001) and IL-10 (p<0.001) secretion after dexamethasone loaded SLN administration, compared to dexamethasone alone at the highest concentration tested (250 nM) at 24h exposure. No IFN-gamma was detected under any conditions and no cytotoxic effects observed even at the highest concentration tested. The incorporation of butyrate and dexamethasone into SLN has a significant positive anti-inflammatory effect in the human inflammatory bowel disease whole-blood model. Copyright 2010 Elsevier B.V.

Full Text Available Several experimental studies suggest that non-steroidal antiinflammatory drugs have chemopreventive effects in mammary carcinogenesis. In this study, tumour suppressive effects of a selective inhibitor of cyclooxygenase-2 (COX-2 etoricoxib in the prevention of N-methyl-Nnitrosourea (NMU-induced mammary carcinogenesis in Sprague-Dawley rats were evaluated. Etoricoxib was administered in the diet, at two concentrations: 1 0.01 mg/g (ETO 0.001% and 2 0.025 mg/g (ETO 0.0025%. Although the chemopreventive effects were not statistically significant, remarkable tumour suppressive effects with the concentration of ETO 0.0025% were recorded. The incidence decreased by 4.31% and tumour frequency per group decreased by 6.67% when compared to the control group. Latency (the period from carcinogen administration to the first tumour appearance increased by 7.28% in dose-dependent manner. The results of our experiments point to dose-dependent tumour suppressive effects of a higher concentration of etoricoxib (ETO 0.0025% when compared to the control group. They suggest that higher etoricoxib concentrations may enhance its tumour suppressive effects.

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.

The inflammatory response to fiber damage is a compelling candidate mechanism for disease exacerbation. The only established pharmacological treatment for DMD is corticosteroids to suppress muscle inflammation, however this treatment is limited by its insufficient therapeutic efficacy and considerable side effects. Recent reports show the therapeutic potential of inhibiting or enhancing pro- or anti-inflammatory factors released from DMD skeletal muscles, resulting in significant recovery from muscle atrophy and dysfunction. We discuss and review the recent findings of DMD inflammation and opportunities for drug development targeting specific releasing factors from skeletal muscles. It has been speculated that nonsteroidal anti-inflammatory drugs targeting specific inflammatory factors are more effective and have less side effects for DMD compared with steroidal drugs. For example, calcium channels, reactive oxygen species, and nuclear factor-κB signaling factors are the most promising targets as master regulators of inflammatory response in DMD skeletal muscles. If they are combined with an oligonucleotide-based exon skipping therapy to restore dystrophin expression, the anti-inflammatory drug therapies may address the present therapeutic limitation of low efficiency for DMD.

2007-01-01

Full Text Available We investigated the effect of etoricoxib, a selective cyclooxygenase-2 inhibitor, and indomethacin, a non-selective cyclooxygenase inhibitor, on experimental periodontitis, and compared their gastrointestinal side effects. A ligature was placed around the second upper left molars of female Wistar rats (160 to 200 g. Animals (6 per group were treated daily with oral doses of 3 or 9 mg/kg etoricoxib, 5 mg/kg indomethacin, or 0.2 mL saline, starting 5 days after the induction of periodontitis, when bone resorption was detected, until the sacrifice on the 11th day. The weight and survival rate were monitored. Alveolar bone loss (ABL was measured as the sum of distances between the cusp tips and the alveolar bone. The gastric mucosa was examined macroscopically and the periodontium and gastric and intestinal mucosa were examined by histopathology. The ongoing ABL was significantly inhibited (P < 0.05 by 3 and 9 mg/kg etoricoxib and by indomethacin: control = 4.08 ± 0.47 mm; etoricoxib (3 mg/kg = 1.89 ± 0.26 mm; etoricoxib (9 mg/kg = 1.02 ± 0.14 mm; indomethacin = 0.64 ± 0.15 mm. Histopathology of periodontium showed that etoricoxib and indomethacin reduced inflammatory cell infiltration, ABL, and cementum and collagen fiber destruction. Macroscopic and histopathological analysis of gastric and intestinal mucosa demonstrated that etoricoxib induces less damage than indomethacin. Animals that received indomethacin presented weight loss starting on the 7th day, and higher mortality rate (58.3% compared to etoricoxib (0%. Treatment with etoricoxib, even starting when ABL is detected, reduces inflammation and cementum and bone resorption, with fewer gastrointestinal side effects.

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.

Non-steroidal anti-inflammatory drugs (NSAI) may elicit various kinds of cutaneous side effects. The commonest ones are non-specific erythematous eruptions, sometimes with a phototoxic distribution, and urticaria. Vasculitis and severe bullous eruptions (Stevens-Johnson's syndrome and Toxic Epidermal Necrolysis) are rare but may have severe outcomes. The overall incidence of cutaneous reactions is about the same for all NSAI, 1 to 3 p. 100, during the clinical studies performed before marketing the drug, but this increases afterwards (up to 45 p. 100 for Benoxaprofen). Drugs with long half-lives may carry a higher risk for severe cutaneous reactions. NSAI are now the main cause of drug induced TEN. Urticarial reactions seem related to pharmacological phenomena while the pathogenic events leading to other kinds of skin reactions remain unknown. An hypersensitivity reaction is postulated. The therapeutic value of corticosteroids for the severe cutaneous side effects of drugs is still controversial.

Nonsteroidal anti-inflammatory drugs (NSAIDs) and selective cyclooxygenase-2 inhibitors may interfere with ovulation and the rupture of the follicle, causing reversible infertility. Literature review. Reversible infertility is shown both in animal and human studies of these drugs. As determined by ultrasound, the drugs may delay or inhibit ovulation. These findings are also confirmed by a few randomized controlled studies showing an increase in time from the luteinizing hormone surge to rupture of the follicle and an increased size of the unruptured follicle. Most of the hormone analyses show values in accordance with the ovulation/menstrual cycle. Also, two epidemiological studies have shown an association between NSAID use and spontaneous abortion. These studies have methodological weaknesses and their findings have to be elucidated in future studies. Women with fertility problems should avoid not only the selective cyclooxygenase-2 inhibitors, but also the traditional NSAIDs. However, women with rheumatic disease responding well to therapy should consult their physicians before stopping treatment. Reduced dose of a NSAID and temporary stop of drug treatment early in the menstrual cycle, or alternative drug treatment, may be a solution. NSAIDs should not be used in the last eight weeks of pregnancy.

Acute nonsteroidal anti-inflammatory drug-induced colitis

Massimo Tonolini

2013-01-01

Full Text Available Resulting from direct toxicity on the bowel mucosa, nonsteroidal anti-inflammatory drug (NSAID-induced colitis is an underestimated although potentially serious condition. Plain abdominal radiographs and multidetector computed tomography allow to identify a right-sided acute colitis with associated pericolonic inflammation, progressively diminished changes along the descending and sigmoid colon, and rectal sparing, consistent with the hypothesized pathogenesis of NSAID colitis. Increased awareness of this condition should reduce morbidity through both prevention and early recognition. High clinical suspicion and appropriate patient questioning, together with consistent instrumental findings, negative biochemistry, and stool investigations should help physicians not to miss this important diagnosis.

Luminescence properties of the complexes of terbium(III) with nonsteroidal anti-inflammatory drugs (ibuprofen and orthofen) were studied. It was demonstrated that in the presence of organic bases (2,2'-dipyridyl and 1,10-phenanthroline) mixed-ligand complexes are formed and the luminescence intensity of terbium(III) increases by a factor of up to 250. The optimum complexation conditions were determined. It was proposed to use these complexes as analytical forms for the luminescence determination of nonsteroidal anti-inflammatory drugs (ibuprofen and orthofen) in pharmaceutical dosage forms. The detection limits are 2 and 0.05 μg/ml, respectively [ru

Full Text Available Parkinson’s disease (PD is the second most common neurodegenerative disease affecting approximately 1.6% of the population over 60 years old. The cardinal motor symptoms are the result of progressive degeneration of substantia nigra pars compacta dopaminergic neurons which are involved in the fine motor control. Currently, there is no cure for this pathology and the cause of the neurodegeneration remains unknown. Several studies suggest the involvement of neuroinflammation in the pathophysiology of PD as well as a protective effect of anti-inflammatory drugs both in animal models and epidemiological studies, although there are controversial reports. In this review, we address evidences of involvement of inflammatory process and possible therapeutic usefulness of anti-inflammatory drugs in PD.

Full Text Available Two simple, rapid, sensitive, precise and economic spectrophotometric methods have been developed for the estimation of etoricoxib in tablet formulation. During the course of study, it was observed that acidic solution of the drug formed colored ion-association complexes with Bromocresol Green (BCG and Bromocresol Purple (BCP which were soluble in chloroform. This property of the drug was followed for the development of colorimetric methods for analysis of drug. The complex of etoricoxib with BCG and BCP showed λmax at 416 nm and 408 nm respectively. These methods were validated statistically. Recovery studies gave satisfactory results indicating that none of common additives and excipients interfere the assay method. The proposed methods are found to be simple, accurate and reproducible that was successfully applied for the analysis of tablet formulation.

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.

Oral nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used in the treatment of pain in fibromyalgia, despite being considered not to be effective. To assess the analgesic efficacy, tolerability (drop-out due to adverse events), and safety (serious adverse events) of oral nonsteroidal anti-inflammatory drugs for fibromyalgia in adults. We searched CENTRAL, MEDLINE, and Embase for randomised controlled trials from inception to January 2017. We also searched the reference lists of retrieved studies and reviews, and online clinical trial registries. We included randomised, double-blind trials of two weeks' duration or longer, comparing any oral NSAID with placebo or another active treatment for relief of pain in fibromyalgia, with subjective pain assessment by the participant. Two review authors independently extracted data and assessed trial quality and potential bias. Primary outcomes were participants with substantial pain relief (at least 50% pain relief over baseline or very much improved on Patient Global Impression of Change scale (PGIC)) or moderate pain relief (at least 30% pain relief over baseline or much or very much improved on PGIC), serious adverse events, and withdrawals due to adverse events; secondary outcomes were adverse events, withdrawals due to lack of efficacy, and outcomes relating to sleep, fatigue, and quality of life. Where pooled analysis was possible, we used dichotomous data to calculate risk difference (RD) and number needed to treat for an additional beneficial outcome (NNT), using standard methods. We assessed the quality of the evidence using GRADE and created a 'Summary of findings' table. Our searches identified six randomised, double-blind studies involving 292 participants in suitably characterised fibromyalgia. The mean age of participants was between 39 and 50 years, and 89% to 100% were women. The initial pain intensity was around 7/10 on a 0 to 10 pain scale, indicating severe pain. NSAIDs tested were etoricoxib 90 mg

Renal Side Effects of Non-Steroidal Anti-Inflammatory Drugs in Neonates

Marc Gewillig

2010-02-01

Full Text Available Non-steroidal anti-inflammatory drugs like ibuprofen or indomethacin are commonly prescribed drugs to induce pharmacologic closure of a patent ductus arteriosus in preterm neonates. Based on a recently published Cochrane meta-analysis, both drugs are equally effective to induce closure. Drug choice can therefore be based on differences in side effects or pharmaco-economic arguments. The current review quantifies the negative impact of either ibuprofen or indomethacin on renal function, including diuresis, glomerular filtration rate and renal tubular function. Both ibuprofen and indomethacin have a quantifiable impact on renal function. However, compared to ibuprofen, the negative impact of indomethacin is more pronounced.

Full Text Available Chronic use of oral nonsteroidal anti-inflammatory drugs (NSAIDs is associated with increased risk of serious gastrointestinal side effects. Therefore, recent trends in the development of NSAIDs aim to reduce the incidence of side effects, and improve patient compliance. One of the strategies to improve efficacy and safety of oral NSAIDs is the development of combination products that contain gastroprotective agents. Several products containing NSAID in combination with proton pump inhibitors (ketoprofen/omeprazole, naproxen/esomeprazole, H2-receptor antagonists (ibuprofen/famotidine, and prostaglandin analogues (diclofenac/misoprostol are currently available on the market. Another approach refer to the special formulation design to allow dose reduction while preserving drug therapeutic efficacy. An example is SoluMatrix® technology, a manufacturing process that produce submicron-sized drug particles with enhanced dissolution and absorption properties. Patented SoluMatrix® technology has been successfully employed to develop low-dose diclofenac, meloxicam, indomethacin and naproxen products. Topical NSAID formulations enable drug delivery to target tissues, while reducing systemic exposure and concomitant side effects associated with oral NSAIDs. Dermal/transdermal NSAID delivery systems are subject of intensive investigation. So far, several 'advanced' drug delivery systems with diclofenac, ibuprofen and ketoprofen have been designed.

Immuno-isolation of islets has the potential to enable the replacement of pancreatic function in diabetic patients. However, host response to the encapsulated islets frequently leads to fibrotic overgrowth with subsequent impairment of the transplanted grafts. Here, we identified and incorporated anti-inflammatory agents into islet-containing microcapsules to address this challenge. In vivo subcutaneous screening of 16 small molecule anti-inflammatory drugs was performed to identify promising compounds that could minimize the formation of fibrotic cell layers. Using parallel non-invasive fluorescent and bioluminescent imaging, we identified dexamethasone and curcumin as the most effective drugs in inhibiting the activities of inflammatory proteases and reactive oxygen species in the host response to subcutaneously injected biomaterials. Next, we demonstrated that co-encapsulating curcumin with pancreatic rat islets in alginate microcapsules reduced fibrotic overgrowth and improved glycemic control in a mouse model of chemically-induced type I diabetes. These results showed that localized administration of anti-inflammatory drug can improve the longevity of encapsulated islets and may facilitate the translation of this technology toward a long-term cure for type I diabetes.

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 Epidemiological studies suggest that nonsteroidal anti-inflammatory drugs (NSAIDs reduce the incidence and mortality of several types of human cancer. However, the molecular mechanisms by which NSAIDs exert their chemopreventive and anticancer effects are not fully understood. Cyclooxygenase 1 (COX-1 and COX-2 are the main targets for NSAIDs. Recent studies demonstrate that COX-2 is overexpressed in many human cancers and may promote tumorigenesis via: (1 stimulation of cancer cell proliferation; (2 increase of tumor angiogenesis; (3 prevention of cancer cell apoptosis; (4 modulation of immunoregulatory reactions; and (5 enhancement of tumor metastasis. NSAIDs may target the signaling molecules (from upstream activators to downstream effectors involved in these mechanisms to attenuate the development and progression of cancer. In this review, we discuss the recent findings with regard to the mechanisms by which NSAIDs inhibit tumorigenesis and will specifically focus on the elucidation of NSAID-induced inhibition of tumor metastasis.

Dandona, Paresh; Chaudhuri, Ajay; Mohanty, Priya; Ghanim, Husam

2007-07-01

This review deals with the recent observations on the pro-inflammatory effects of glucose and the anti-inflammatory actions of insulin. Apart from being novel, they are central to our understanding of why hyperglycemia is a prognosticator of bad clinical outcomes including patients with acute coronary syndromes, stroke and in patients in the intensive care unit. The pro-inflammatory effect of glucose as well as that of other macronutrients including fast food meals provides the basis of chronic oxidative stress and inflammation in the obese and their propensity to atherosclerotic disease. The anti-inflammatory action of insulin provides a neutralizing effect to balance macronutrient induced inflammation on the one hand and the possibility of using insulin as an anti-inflammatory drug on the other. The actions of macronutrients and insulin described above explain why insulin resistant states like obesity and type 2 diabetes are associated with oxidative stress, inflammation and atherosclerosis. They also suggest that insulin may be antiatherogenic.

The nonhormonal medical treatment can be divided into empirical, when the cause has not been identified, and nonempirical, if the pathogenic mechanism causing male infertility can be solved or ameliorated. The empirical nonhormonal medical treatment has been proposed for patients with idiopathic or noncurable oligoasthenoteratozoospermia and for normozoospermic infertile patients. Anti-inflammatory, fibrinolytic, and antioxidant compounds, oligo elements, and vitamin supplementation may be prescribed. Infection, inflammation, and/or increased oxidative stress often require a specific treatment with antibiotics, anti-inflammatory drugs, and/or antioxidants. Combined therapies can contribute to improve sperm quality.

Antimicrobial agents including antituberculosis (anti-TB) agents are the most common cause of idiosyncratic drug-induced liver injury (DILI) and drug-induced liver failure across the world. Better molecular and genetic biomarkers are acutely needed to help identify those at risk of liver injury particularly for those needing antituberculosis therapy. Some antibiotics such as amoxicillin-clavulanate and isoniazid consistently top the lists of agents in retrospective and prospective DILI databases. Central nervous system agents, particularly antiepileptics, account for the second most common class of agents implicated in DILI registries. Hepatotoxicity from older antiepileptics such as carbamazepine, phenytoin, and phenobarbital are often associated with hypersensitivity features, whereas newer antiepileptic drugs have a more favorable safety profile. Antidepressants and nonsteroidal anti-inflammatory drugs carry very low risk of significant liver injury, but their prolific use make them important causes of DILI. Early diagnosis and withdrawal of the offending agent remain the mainstays of minimizing hepatotoxicity. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

2017-01-01

Full Text Available Context: The lipopolysaccharide (LPS-induced cytokine release and oxidative stress are validated experimental parameters used to test anti-inflammatory activity. We investigated the effects of homoeopathic mother tinctures, 6 CH, 30 CH and 200 CH dilutions of Arnica montana, Thuja occidentalis and Bryonia alba against LPS (1 μg/ml-induced cytokine release from RAW-264.7 cells and human whole-blood culture. Materials and Methods: For in vivo evaluations, mice were orally treated with 0.1 ml drug dilutions twice a day for 5 days followed by an intraperitoneal injection of 0.5 mg/kg LPS. After 24 h, the mice were sacrificed and serum levels of pro-inflammatory cytokines and nitric oxide were determined. The extent of oxidative stress was determined in the liver homogenates as contents of reduced glutathione, malondialdehyde, superoxide dismutase and catalase. Results: The tested drug dilutions significantly reduced in vitro LPS-induced release of tumour necrosis factor-α, interleukin-1 (IL-1 and IL-6 from the RAW-264.7 cells and human whole blood culture. Similar suppression of cytokines was evident in mice serum samples. These drugs also protected mice from the LPS-induced oxidative stress in liver tissue. Conclusions: Our findings substantiate the protective effects of Arnica, Thuja and Bryonia homoeopathic dilutions against LPS-induced cytokine elevations and oxidative stress. This study authenticates the claims of anti-inflammatory efficacy of these homoeopathic drugs.

2009-01-01

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

Non-Steroidal Anti-Inflammatory Drug Use and the Risk of Acute Myocardial Infarction in the General German Population: A Nested Case-Control Study.

2017-09-01

Use of non-steroidal anti-inflammatory drugs (NSAIDs) has been associated with an increased relative risk of acute myocardial infarction (AMI), but the label warnings refer particularly to patients with cardiovascular risk factors. The magnitude of relative AMI risk for patients with and without cardiovascular risk factors varies between studies depending on the drugs and doses studied. The aim of our study was to estimate population-based relative AMI risks for individual and widely used NSAIDs, for a cumulative amount of NSAID use, and for patients with and without a prior history of cardiovascular risk factors. Based on data from the German Pharmacoepidemiological Research Database (GePaRD) of about 17 million insurance members from four statutory health insurance providers, for the years 2004-2009, a nested case-control study was conducted within a cohort of 3,476,931 new NSAID users classified into current, recent, or past users. Up to 100 controls were matched to each case by age, sex, and length of follow-up using risk set sampling. Multivariable conditional logistic regression was applied to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Duration of NSAID use was calculated by the cumulative amount of dispensed defined daily doses (DDDs), and stratified analyses were conducted for potential effect modifiers. Overall, 17,236 AMI cases were matched to 1,714,006 controls. Elevated relative AMI risks were seen for current users of fixed combinations of diclofenac with misoprostol (OR 1.76, 95% CI 1.26-2.45), indometacin (1.69, 1.22-2.35), ibuprofen (1.54, 1.43-1.65), etoricoxib (1.52, 1.24-1.87), and diclofenac (1.43, 1.34-1.52) compared with past use. A low cumulative NSAID amount was associated with a higher relative AMI risk for ibuprofen, diclofenac, and indometacin. The relative risk associated with current use of diclofenac, fixed combinations of diclofenac with misoprostol, etoricoxib, and ibuprofen was highest in the younger age group

2008-02-01

Full Text Available Abstract Background Desmoid tumours or fibromatoses are rare entities characterized by the benign proliferation of fibroblasts, which can be life-threatening due to their locally aggressive properties. Surgery is widely accepted as the first line of treatment for extra-abdominal desmoids; however, it is not recommended for intra-abdominal desmoids because of the high-risk of recurrence and difficulties with the operation. Here, we report on a patient with sporadic intra-abdominal desmoid tumours, who showed partial response following the intake of non-steroidal anti-inflammatory drugs. Case presentation A 73-year-old man presented with swelling and pain of the right leg. Computed tomography showed an abnormal multilocular soft-tissue mass (95 × 70 mm in the right pelvis, which was revealed by biopsy to be a desmoid tumour. Immunohistochemical analysis showed that the tumour cells expressed vimentin, but not smooth-muscle actin, CD34, or desmin. Very few Ki-67-positive cells were found. Non-cytotoxic treatment with etodolac (200 mg/day was chosen because of the patient's age, lack of bowel obstruction, and the likelihood of prostate cancer. Two years after the commencement of non-steroidal anti-inflammatory drug administration, computed tomography showed a decrease in tumour size (63 × 49 mm, and the disappearance of intratumoural septa. Conclusion Our case report suggests that non-steroidal anti-inflammatory drug treatment should be taken into consideration for use as first-line treatment in patients with sporadic intra-abdominal desmoid tumours.

Viljoen, A; Mncwangi, N; Vermaak, I

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

Use of potentially inappropriate medications may result in increased morbidity, mortality and resource utilisation. Due to polypharmacy and age-related decline in renal function the elderly population is at particular risk. Therefore, the Beers Criteria include use of nonsteroidal anti-inflammatory drugs in chronic renal failure stage 4 and 5 as these drugs may worsen renal function. According to the summary of product characteristics, the nonsteroidal anti-inflammatory drugs ibuprofen and diclofenac are contraindicated in these patients. Objective was to assess the extent of nonsteroidal anti-inflammatory drug use in nursing homes with a focus on residents with severe renal failure. Multi-centre cross-sectional study in 21 German nursing homes. The study population comprised residents for whom at least one serum creatinine value and information about sex were available, so that creatinine clearance rate could be estimated. In all, 685 of 852 residents were included as they fulfilled the abovementioned criteria. Renal failure was severe (estimated creatinine clearance rate renal failure (20.8 %). With one exception, all residents prescribed nonsteroidal anti-inflammatory drugs with severe renal failure were treated with at least one nonsteroidal anti-inflammatory drug that was contraindicated due to the underlying renal function. Notwithstanding their classification as potentially inappropriate medications and underlying contraindications, use of nonsteroidal anti-inflammatory drugs is common among nursing home residents with severe renal failure.

Full Text Available The protein binding of non-steroidal anti-inflammatory drugs flurbiprofen, ketoprofen and etodolac with human serum albumin (HSA was investigated using indirect chiral high performance liquid chromatography (HPLC and ultrafiltration techniques. S-(–-1-(1-naphthyl-ethylamine (S-NEA was utilized as chiral derivatization reagent and pre-column derivatization RP-HPLC method was established for the separation and assay of the three pairs of enantiomer. The method had good linear relationship over the investigated concentration range without interference. The average extraction efficiency was higher than 85% in different systems, and the intra-day and inter-day precisions were less than 15%. In serum albumin, the protein binding of etodolac enantiomers showed significant stereoselectivity that the affinity of S-enantiomer was stronger than R-enantiomer, and the stereoselectivity ratio reached 6.06; Flurbiprofen had only weak stereoselectivity in HSA, and ketoprofen had no stereoselectivity at all. Scatchard curves showed that all the three chiral drugs had two types of binding sites in HSA.

In addition to inhibiting the cyclooxygenasemediated biosynthesis of prostanoids, various widely used non-steroidal anti-inflammatory drugs (NSAIDs) enhance endocannabinoid signaling by blocking the anandamidedegrading membrane enzyme, fatty acid amide hydrolase (FAAH). The X-ray structure of FAAH in complex with the NSAID carprofen, along with studies of site-directed mutagenesis, enzyme activity assays, and nuclear magnetic resonance, now reveal the molecular details of this interaction, providing information that may guide the design of dual FAAH-cyclooxygenase inhibitors with superior analgesic efficacy.

The Unani eye drop is an ophthalmic formulation prepared for its beneficial effects in the inflammatory and allergic conditions of the eyes. In the present study, the Unani eye drop formulation was prepared and investigated for its anti-inflammatory and antihistaminic activity, using in vivo and in vitro experimental models respectively. The Unani eye drop formulation exhibited significant anti-inflammatory activity in turpentine liniment-induced ocular inflammation in rabbits. The preparation also showed antihistaminic activity in isolated guinea-pig ileum. The anti-inflammatory and antihistaminic activity of eye drop may be due to presence of active ingredients in the formulation. Although there are many drugs in Unani repository which are mentioned in classical books or used in Unani clinical practice effectively in treatment of eye diseases by various Unani physicians. Inspite of the availability of vast literature, there is a dearth of commercial Unani ocular preparations. So, keeping this in mind, the eye drop formulation was prepared and its anti-inflammatory and antihistaminic activity was carried out in animal models. Thus, in view of the importance of alternative anti-inflammatory and antiallergic drugs, it becomes imperative to bring these indigenous drugs to the front foot and evaluate their activities.

Hypochlorous acid (HOCl) is the most powerful oxidant produced by human neutrophils, and should therefore be expected to contribute to the damage caused by these inflammatory cells. It is produced from H2O2 and Cl- by the heme enzyme myeloperoxidase (MPO). We used a H2O2-electrode to assess the ability of a variety of anti-inflammatory drugs to inhibit conversion of H2O2 to HOCl. Dapsone, mefenamic acid, sulfapyridine, quinacrine, primaquine and aminopyrine were potent inhibitors, giving 50% inhibition of the initial rate of H2O2 loss at concentrations of about 1 microM or less. Phenylbutazone, piroxicam, salicylate, olsalazine and sulfasalazine were also effective inhibitors. Spectral investigations showed that the inhibitors acted by promoting the formation of compound II, which is an inactive redox intermediate of MPO. Ascorbate reversed inhibition by reducing compound II back to the active enzyme. The characteristic properties that allowed the drugs to inhibit MPO reversibly were ascertained by determining the inhibitory capacity of related phenols and anilines. Inhibition increased as substituents on the aromatic ring became more electron withdrawing, until an optimum reduction potential was reached. Beyond this optimum, their inhibitory capacity declined. The best inhibitor was 4-bromoaniline which had an I50 of 45 nM. An optimum reduction potential enables inhibitors to reduce MPO to compound II, but prevents them from reducing compound II back to the active enzyme. Exploitation of this optimum reduction potential will help in targeting drugs against HOCl-dependent tissue damage.

Nonsteroidal anti-inflammatory drug gastropathy: new avenues for safety.

Science.gov (United States)

Roth, Sanford H

2011-01-01

Chronic oral or systemic nonselective nonsteroidal anti-inflammatory drug (NSAID) therapy, ubiquitously used by physicians to treat osteoarthritis-associated pain, is associated with a wide range of symptomatic adverse events, the most frequent and serious of which is gastropathy. Although cardiovascular and renal problems are a very real concern, they are significantly less frequent. These complications can be life-threatening in at-risk populations such as older adults, who are common users of long-term oral systemic NSAID therapy. Topical NSAID formulations deliver effective doses of analgesics directly to the affected joints, thereby limiting systemic exposure and potentially the risk of systemic adverse events, such as gastropathy and serious cardiovascular events. There are currently two topical NSAIDs approved by the US Food and Drug Administration for osteoarthritis-associated pain, as well as for the signs and symptoms of osteoarthritis. This review discusses the relative safety, and the gastrointestinal, cardiovascular, and renal risks of chronic oral or systemic NSAID therapy and topical NSAID formulations in patients with osteoarthritis.

Non-steroid anti-inflammatory drugs (NSAID) were found to have hemostimulating effect in mice after irradiation. This effect was rather definite under irradiation conditions modified by dose fractioning or radioprotective chemicals. NSAID application during fractionated irradiation with midlethal integral dose leads to almost complete recovery of bone marrow hemopoiesis by the 9th day of radiation illness. NSAID usage combined with chemical radioprotectors provides effective hemopoiesis stimulation leading to survival increase in animals, irradiated with absolutely lethal doses. (author)

Although non-steroidal anti-inflammatory drugs and acetaminophen have no proven efficacy against neuropathic pain, they are frequently prescribed for neuropathic pain patients. We examined whether the combination of opioids (tramadol and morphine) with indomethacin or acetaminophen produce favorable effects on neuropathic pain and compared the efficacy for neuropathic pain with that for inflammatory pain. The carrageenan model was used as the inflammatory pain model while the tibial neuroma transposition (TNT) model was used as the neuropathic pain model. The tibial nerve is transected in the TNT model, with the tibial nerve stump then transpositioned to the lateral aspect of the hindlimb. Neuropathic pain (mechanical allodynia and neuroma pain) is observed after TNT injury. Drugs were administered orally. In the carrageenan model, all drugs produced anti-allodynic effects and all drug combinations, but not tramadol + indomethacin combination, produced synergistic anti-allodynic effects. In the TNT model, tramadol and morphine, but not acetaminophen and indomethacin, produced anti-neuropathic pain effects. In the combination, with the exception of morphine + acetaminophen combination, both acetaminophen and indomethacin reduced the 50% effective dose (ED50) of tramadol and morphine as compared with the ED50s for the single drug study in the TNT model. The ED50s of tramadol and morphine in the carrageenan combination test were not statistically significantly different from the ED50s in the TNT model combination study. The combination of opioids with indomethacin or acetaminophen produced a synergistic analgesic effect both in inflammatory and neuropathic pain with some exceptions. The efficacy of these combinations for neuropathic pain was not different from that for inflammatory pain.

1981-04-01

A comparison has been made of the distribution of some new radioactively-labelled non-steroid anti-inflammatory (NSAI) drugs or pro-drugs with their respective progenitors and/or standard acidic NSAI drugs (i.e. aspirin, indomethacin and phenylbutazone), using whole body autoradiography and scintillation counting. The object of this study was to establish if the distribution of these new NSAI drugs may contribute to changes in their side-, or therapeutic effects compared with the older drugs. All the NSAI drugs accumulated in those tissues wherein the principle therapeutic and side-effects are manifest. The accumulation in inflamed tissues occurs regardless of the structural type of NSAI drugs, i.e. with specific accumulation occurring in this tissue of the acidic drugs or their acidic metabolites. New aspects of the distribution of the acetyl moiety of aspirin are reported which may be significant in relation to the side-effects induced by this drug.

Is there a future for andrographolide to be an anti-inflammatory drug? Deciphering its major mechanisms of action.

Andrographis paniculata has long been part of the traditional herbal medicine system in Asia and in Scandinavia. Andrographolide was isolated as a major bioactive constituent of A. paniculata in 1951, and since 1984, andrographolide and its analogs have been scrutinized with modern drug discovery approach for anti-inflammatory properties. With this accumulated wealth of pre-clinical data, it is imperative to review and consolidate different sources of information, to decipher the major anti-inflammatory mechanisms of action in inflammatory diseases, and to provide direction for future studies. Andrographolide and its analogs have been shown to provide anti-inflammatory benefits in a variety of inflammatory disease models. Among the diverse signaling pathways investigated, inhibition of NF-κB activity is the prevailing anti-inflammatory mechanism elicited by andrographolide. There is also increasing evidence supporting endogenous antioxidant defense enhancement by andrographolide through Nrf2 activation. However, the exact pathway leading to NF-κB and Nrf2 activation by andrographolide has yet to be elucidated. Validation and consensus on the major mechanistic actions of andrographolide in different inflammatory conditions are required before translating current findings into clinical settings. There are a few clinical trials conducted using andrographolide in fixed combination formulation which have shown anti-inflammatory benefits and good safety profile. A concerted effort is definitely needed to identify potent andrographolide lead compounds with improved pharmacokinetics and toxicological properties. Taken together, andrographolide and its analogs have great potential to be the next new class of anti-inflammatory agents, and more andrographolide molecules are likely moving towards clinical study stage in the near future.

1990-10-01

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.

Antibiotic and Anti-Inflammatory Therapies for Cystic Fibrosis

Chmiel, James F.; Konstan, Michael W.; Elborn, J. Stuart

2013-01-01

Cystic fibrosis (CF) lung disease is characterized by chronic bacterial infection and an unremitting inflammatory response, which are responsible for most of CF morbidity and mortality. The median expected survival has increased from 38 yr now. This dramatic improvement, although not great enough, is due to the development of therapies directed at secondary disease pathologies, especially antibiotics. The importance of developing treatments directed against the vigorous inflammatory response was realized in the 1990s. New therapies directed toward the basic defect are now visible on the horizon. However, the impact of these drugs on downstream pathological consequences is unknown. It is likely that antibiotics and anti-inflammatory drugs will remain an important part of the maintenance regimen for CF in the foreseeable future. Current and future antibiotic and anti-inflammatory therapies for CF are reviewed. PMID:23880054

Although inflammation is a biological phenomenon that exists to protect the host against infections and/or related problems, its unceasing activation results in the aggravation of several medical conditions. Imidazoles, whether natural or synthetic, are molecules related to a broad spectrum of biological effects, including anti-inflammatory properties. In this study, we screened eight novel small molecules of the imidazole class synthesized by our research group for their in vitro anti-inflammatory activity. The effect of the selected molecules was confirmed in an in vivo inflammatory model. We also analyzed whether the effects were caused by inhibition of nuclear factor kappa B (NF-κB) transcription factor transmigration. Of the eight imidazoles tested, methyl 1-allyl-2-(4-fluorophenyl)-5-phenyl-1H-imidazole-4-acetate (8) inhibited nitric oxide metabolites and pro-inflammatory cytokine (TNF-α, IL-6, and IL-1β) secretion in J774 macrophages stimulated with LPS. It also attenuated leukocyte migration and exudate formation in the pleural cavity of mice challenged with carrageenan. Furthermore, imidazole 8 reverted the oxidative stress pattern triggered by carrageenan in the pleural cavity by diminishing myeloperoxidase, superoxide dismutase, catalase, and glutathione S-transferase activities and reducing the production of nitric oxide metabolites and thiobarbituric acid-reactive substances. Finally, these effects can be attributed, at least in part, to the ability of this compound to prevent NF-κB transmigration. In this context, our results demonstrate that imidazole 8 has promising potential as a prototype for the development of a new anti-inflammatory drug to treat inflammatory conditions in which NF-κB and oxidative stress play a prominent role.

Full Text Available Background: 1,2,3-trisubstituted imidazolidines are reported to have better anti-inflammatory activity than the reference drug indomethacin. Similarly, naphthalene nucleus plays a significant role in the drug design. Nabumetone and naproxen are naphthalene nucleus containing anti-inflammatory drugs available in the market. There are also reports that compounds having two naphthalene rings incorporated with a heterocyclic nucleus have good medicinal value. Based on these reports it was planned to synthesize hybrid compounds containing two naphthalene rings with imidazolidine nucleus. Aim: To obtain potent compounds having anti-inflammatory and analgesic activities with reduced gastrointestinal side effects. Materials and Methods: The reaction scheme includes the reaction between 1-naphthaldehyde with ethylenediamine to obtain diSchiff′s base (1 Reduction of this diSchiff′s base with NaBH 4 gave tetrahydrodiSchiff′s base (2 Further cyclization of 2 with appropriate aldehyde in the presence of ethanol formed 2-substituted-1,3-bis(1-naphthylmethyl-imidazolidine derivatives (3a-n. The structures of these compounds were established on the basis of spectral data. All these compounds were tested for their anti-inflammatory, analgesic, ulcerogenic, and lipid peroxidation activities. Results and Discussion: The tested compounds (3a-n showed anti-inflammatory activity ranging between 27.61% and 53.43%. The compound 3h showed the highest activity of 53.43% and 3n showed 53.02% inhibition at 20 mg/kg dose in rats compared with the standard drug indomethacin which showed 61.45% inhibition at the same dose. It was encouraging to note that both the compounds showed reduced ulcerogenic activity (less than half compared to the standard drug indomethacin.

Full Text Available Background: Volatile oils obtained from lemon grass [Cymbopogon citratus (DC. Stapf, Poaceae family] are used in traditional medicine as remedies for the treatment of various diseases. Aims: In the present study, lemon grass essential oil (LGEO was evaluated for its in vivo topical and oral anti-inflammatory effects, and for its in vitro antifungal activity using both liquid and vapor phases. Methods: The chemical profile of LGEO as determined by gas chromatography–mass spectrometry analysis revealed two major components: geranial (42.2%, and neral (31.5%. The antifungal activity of LGEO was evaluated against several pathogenic yeasts and filamentous fungi using disc diffusion and vapor diffusion methods. Results: LGEO exhibited promising antifungal effect against Candida albicans, C. tropicalis, and Aspergillus niger, with different inhibition zone diameters (IZDs (35–90 mm. IZD increased with increasing oil volume. Significantly, higher anti-Candida activity was observed in the vapor phase. For the evaluation of the anti-inflammatory effect, LGEO (10 mg/kg, administered orally significantly reduced carrageenan-induced paw edema with a similar effect to that observed for oral diclofenac (50 mg/kg, which was used as the positive control. Oral administration of LGEO showed dose-dependent anti-inflammatory activity. In addition, topical application of LGEO in vivo resulted in a potent anti-inflammatory effect, as demonstrated by using the mouse model of croton oil-induced ear edema. To our knowledge, this is the first such report to be published. The topical application of LGEO at doses of 5 and 10 µL/ear significantly reduced acute ear edema induced by croton oil in 62.5 and 75% of the mice, respectively. In addition, histological analysis clearly confirmed that LGEO inhibits the skin inflammatory response in animal models. Conclusion: Results of the present study indicate that LGEO has a noteworthy potential for the development of drugs for

Prevention of nonsteroidal anti-inflammatory drug-induced gastropathy.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used for their analgesic, antipyretic, and antiinflammatory properties, and aspirin is increasingly employed in the primary and secondary prevention of cardiovascular disease and ischemic stroke. Despite undisputed therapeutic efficacy for these indications, all NSAIDs impart a considerable risk of peptic ulcer disease and upper gastrointestinal hemorrhage. A growing body of evidence supports an association between non-aspirin NSAIDs and acute coronary syndromes, and an expanding understanding of the gastroduodenal effects of aspirin, COX-2 selective agents, clopidogrel, and Helicobacter pylori synergism fuel controversies in NSAID use. In this review, we discuss risk stratification of patients taking NSAIDs and the appropriate application of proven gastro-protective strategies to decrease the incidence of gastrointestinal hemorrhage based upon an individualized assessment of risk for potential toxicities. Prevention of NSAID-related gastropathy is an important clinical issue, and therapeutic strategies for both the primary and secondary prevention of adverse events are continually evolving.

The anti-inflammatory drugs possess many serious side effects at doses commonly prescribed. It is really important to discover novel regulators of inflammation from natural sources with minimal adverse effects. Schinus areira L. is a plant native from South America and is used in folk medicine as an anti-inflammatory herb. For this study, the activity of aqueous extracts on inflammation and the effect on superoxide anion production in mice macrophages were assayed. Aqueous extracts were prepared by soaking herbs in cold water (cold extract), boiling water (infusion), and simmering water (decoction). Cold extract possess an anti-inflammatory activity. Decoction and infusion showed pro-inflammatory activity. Cold extract increased the production of superoxide anion. It has been proposed to use diverse methods to obtain extracts of S. areira L. with different effects. Cold extract, decoction, and infusion could be utilized as extracts or as pharmacological preparations for topical application.

Several lines of evidence suggest a role of inflammatory processes in Parkinson disease, although it is still unclear whether inflammation is a cause or rather a consequence of neurodegeneration. In a prospective population-based cohort study among 6,512 participants aged >or=55 years, with repeated in-person examination, we evaluated the association between cumulative use of nonsteroidal anti-inflammatory drugs (NSAIDs) and the risk of Parkinson disease. Complete information on filled prescriptions was available from automated pharmacy records. Data were analyzed by means of Cox proportional hazards regression analysis, adjusted for age, sex, smoking habits and coffee consumption. After an average 9.4 years of follow-up, 88 new cases of Parkinson disease were detected. No association was found between use of NSAIDs and the risk of Parkinson disease (adjusted hazard ratio for any NSAID use, 1.50; 95% confidence interval, 0.95-2.37). Our findings do not support the hypothesis that NSAIDs might decrease the risk of Parkinson disease. (c) 2007 S. Karger AG, Basel.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are often coadministered with proton-pump inhibitors (PPIs) to reduce NSAID-induced gastrointestinal (GI) adverse events. This coadministration is generally regarded as safe, and is included in many of the guidelines on NSAID prescription. However, recent evidence indicates that the GI risks associated with NSAIDs can be potentiated when they are combined with PPIs. This review discusses the GI effects and complications of NSAIDs and how PPIs may potentiate these effects, options for prevention of GI side effects, and appropriate use of PPIs in combination with NSAIDs.

Oaks, J. Lindsay; Meteyer, Carol U.; Miller, R. Eric; Fowler, Murray E.

2012-01-01

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.

In this study, gelatin and carboxymethyl tamarind gum (CTG) were chemically cross-linked to control the delivery of aceclofenac from their interpenetrating network (IPNs). Infrared spectra, thermal and X-ray data supported that drug and polymer was compatible in the composite hydrogels. Irregularly shaped IPN microstructures were seen under field emission scanning electron microscope (FE-SEM). IPN system was capable of entrapping about 96% of the drug fed. CTG in IPN structures suppressed the drug release rate in HCl solution (pH 1.2); however extended the same in phosphate buffer solution (pH 6.8). The drug release was controlled by polymer chain relaxation/swelling and simple diffusion in vitro. The anti-inflammatory activity of drug-loaded biocomposites lasted over 7 h in albino rats, thus suggesting their potential as an anti-inflammatory therapeutics. - Highlights: • Novel gelatin-carboxymethyl tamarind gum biocomposites was synthesized. • FTIR, thermal and X-ray study ensured compatibility between drug and polymers. • FE-SEM image revealed irregular shape of the IPN microstructures. • In vivo anti-inflammatory pharmacodynamics in rat model was encouraging.

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

Science.gov (United States)

Utzeri, Erika; Usai, Paolo

2017-06-14

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.

[Meloxicam: the golden mean of nonsteroidal anti-inflammatory drugs].

Science.gov (United States)

Karateev, A E

2014-01-01

Nonsteroidal anti-inflammatory drugs (NSAIDs) are most commonly used to treat acute and chronic pain in locomotor system (LMS) diseases. However, their administration may be accompanied by the development of dangerous complications as organic and functional disorders of the cardiovascular system (CVS) and gastrointestinal tract (GIT). Physicians have currently a wide range of NSAIDs at their disposal; but none of the representatives of this group can be considered the best. Thus, highly selective cyclooxygenase-2 inhibitors (Coxibs) are substantially safer for GIT; however, their use is clearly associated with the increased risk of severe cardiovascular events. Nonselective NSAIDs, such as naproxen or ketoprofen, are safer for CVS, but more frequently cause significant GIT organic and functional disorders. Moderately selective NSAIDs, such as meloxicam (movalis), conceivably could be the most acceptable choice for treating the majority of patients in this situation. This drug has been long and extensively used in global clinical practice and has gained the confidence of physicians and patients. The major benefits of meloxicam are its proven efficacy, convenient treatment regimen, relatively low risk of complications as organic and functional disorders of the GIT and CVD and good compatibility with low-dose aspirin.

Nonsteroidal anti-inflammatory drug gastropathy: new avenues for safety

Roth SH

2011-05-01

Full Text Available Sanford H RothArizona Research and Education, Arthritis Laboratory, Arizona State University, Phoenix, AZ, USAAbstract: Chronic oral or systemic nonselective nonsteroidal anti-inflammatory drug (NSAID therapy, ubiquitously used by physicians to treat osteoarthritis-associated pain, is associated with a wide range of symptomatic adverse events, the most frequent and serious of which is gastropathy. Although cardiovascular and renal problems are a very real concern, they are significantly less frequent. These complications can be life-threatening in at-risk populations such as older adults, who are common users of long-term oral systemic NSAID therapy. Topical NSAID formulations deliver effective doses of analgesics directly to the affected joints, thereby limiting systemic exposure and potentially the risk of systemic adverse events, such as gastropathy and serious cardiovascular events. There are currently two topical NSAIDs approved by the US Food and Drug Administration for osteoarthritis-associated pain, as well as for the signs and symptoms of osteoarthritis. This review discusses the relative safety, and the gastrointestinal, cardiovascular, and renal risks of chronic oral or systemic NSAID therapy and topical NSAID formulations in patients with osteoarthritis.Keywords: NSAIDs, osteoarthritis, topical administration, synovial fluid, peptic ulcer, Helicobacter pylori

LPS-induced lung inflammation in marmoset monkeys - an acute model for anti-inflammatory drug testing.

Sophie Seehase

Full Text Available Increasing incidence and substantial morbidity and mortality of respiratory diseases requires the development of new human-specific anti-inflammatory and disease-modifying therapeutics. Therefore, new predictive animal models that closely reflect human lung pathology are needed. In the current study, a tiered acute lipopolysaccharide (LPS-induced inflammation model was established in marmoset monkeys (Callithrix jacchus to reflect crucial features of inflammatory lung diseases. Firstly, in an ex vivo approach marmoset and, for the purposes of comparison, human precision-cut lung slices (PCLS were stimulated with LPS in the presence or absence of the phosphodiesterase-4 (PDE4 inhibitor roflumilast. Pro-inflammatory cytokines including tumor necrosis factor-alpha (TNF-α and macrophage inflammatory protein-1 beta (MIP-1β were measured. The corticosteroid dexamethasone was used as treatment control. Secondly, in an in vivo approach marmosets were pre-treated with roflumilast or dexamethasone and unilaterally challenged with LPS. Ipsilateral bronchoalveolar lavage (BAL was conducted 18 hours after LPS challenge. BAL fluid was processed and analyzed for neutrophils, TNF-α, and MIP-1β. TNF-α release in marmoset PCLS correlated significantly with human PCLS. Roflumilast treatment significantly reduced TNF-α secretion ex vivo in both species, with comparable half maximal inhibitory concentration (IC(50. LPS instillation into marmoset lungs caused a profound inflammation as shown by neutrophilic influx and increased TNF-α and MIP-1β levels in BAL fluid. This inflammatory response was significantly suppressed by roflumilast and dexamethasone. The close similarity of marmoset and human lungs regarding LPS-induced inflammation and the significant anti-inflammatory effect of approved pharmaceuticals assess the suitability of marmoset monkeys to serve as a promising model for studying anti-inflammatory drugs.

Full Text Available Charles E Argoff1, F Michael Gloth2 1Albany Medical College and Comprehensive Pain Center, Albany Medical Center, Albany, NY, USA; 2Johns Hopkins University School of Medicine, Baltimore, MD, USA Abstract: Osteoarthritis is common in patients ≥65 years of age. Although nonsteroidal anti-inflammatory drugs (NSAIDs are often prescribed for osteoarthritis pain, they pose age-related cardiovascular, renal, and gastrointestinal risks. Two topical NSAIDs, diclofenac sodium 1% gel (DSG and diclofenac sodium 1.5% in 45.5% dimethylsulfoxide solution (D-DMSO, are approved in the US for the treatment of osteoarthritis pain. Topical NSAIDs have shown efficacy and safety in knee (DSG, D-DMSO and hand (DSG osteoarthritis. Analyses of data from randomized controlled trials of DSG in hand and knee osteoarthritis demonstrate significant improvement of pain and function in both younger patients (<65 years and older patients (≥65 years and suggest good safety and tolerability. However, long-term safety data in older patients are limited. Topical NSAIDs can ease medication administration and help address barriers to pain management in older patients, such as taking multiple medications and inability to swallow, and are a valuable option for long-term care providers.

Neostigmine interactions with non steroidal anti-inflammatory drugs.

Science.gov (United States)

Miranda, Hugo F; Sierralta, Fernando; Pinardi, Gianni

2002-04-01

1. The common mechanism of action of non-steroidal anti-inflammatory drugs (NSAIDs) is the inhibition of the enzyme cyclo-oxygenase (COX), however, this inhibition is not enough to completely account for the efficacy of these agents in several models of acute pain. 2. It has been demonstrated that cholinergic agents can induce antinociception, but the nature of the interaction between these agents and NSAIDs drugs has not been studied. The present work evaluates, by isobolographic analysis, the interactions between the cholinergic indirect agonist neostigmine (NEO) and NSAIDs drugs, using a chemical algesiometric test. 3. Intraperitoneal (i.p.) or intrathecal (i.t.) administration of NEO and of the different NSAIDs produced dose-dependent antinociception in the acetic acid writhing test of the mouse. 4. The i.p. or i.t. co-administration of fixed ratios of ED(50) fractions of NSAIDs and NEO, resulted to be synergistic or supra-additive for the combinations ketoprofen (KETO) and NEO, paracetamol (PARA) and NEO) and diclofenac (DICLO) and NEO administered i.p. However, the same combinations administered i.t. were only additive. In addition, the combinations meloxicam (MELO) and NEO and piroxicam (PIRO) and NEO, administered either i.p. or i.t., were additive. 5. The results suggest that the co-administration of NEO with some NSAIDs (e.g. KETO, PARA or DICLO) resulted in a synergistic interaction, which may provide evidence of supraspinal antinociception modulation by the increased acetylcholine concentration in the synaptic cleft of cholinergic interneurons. The interaction obtained between neostigmine and the NSAIDs could carry important clinical implications.

THE FACTS: Non steroidal anti-inflammatory drugs (NSAI), except aspirin, are classically contraindicated during pregnancy. Nevertheless, they are widely used, in particular by the obstetricians. During pregnancy, the potential toxicity of these drugs is double, maternal and fetal. The maternal toxicity is comparable to that, already known in adults, with however, some particularities at the time of labor and delivery. The fetal toxicity is mainly renal and cardiovascular, with the NSAI responsible for oligoamniosis and premature closure of the arterial canal of the fetus. On the other hand, the use of these molecules during breast-feeding does not seem source of adverse events, notably in the newborn. THE VARIOUS MOLECULES: Among the family of non-selective non-steroidal anti-inflammatories, indications and adverse events of the various molecules differ considerably. Moreover, whereas the majority of these molecules are non-selective, i.e. inhibiting the two isoforms of cyclooxygenase, new therapeutics, specifically inhibiting cyclooxygenase-2, are now available. Few studies have been published concerning their prescription during pregnancy and breast-feeding and their maternal and fetal side effects remain ignored by most of the practitioners.

The purpose of the present study was to evaluate the anti-inflammatory activity of Shirishavaleha prepared from two different parts of Shirisha (Albizia lebbeck Benth.), viz. the bark (Twak) and the heartwood (Sara). The activity was screened in the carrageenan-induced rat paw edema model in albino rats. The raw materials were collected and authenticated in the university and the trial formulations were prepared by following standard classical guidelines. Randomly selected animals were divided into four groups of six animals each. The test drugs were administered orally at a dose of 1.8 g/kg for 5 days. Phenylbutazone was used as the standard anti-inflammatory drug for comparison. Between the two different test samples studied, the formulation made from heartwood showed a weak anti-inflammatory activity in this model while that made from the bark produced a considerable suppression of edema after 6 h. It appears that the bark sample would be preferable for clinical use.

Deregulation in prostaglandin (PG) biosynthesis, severe oxidative stress, inflammation and apoptosis contribute to the pathogenesis of nonsteroidal anti-inflammatory drug (NSAID)-induced gastropathy. Unfortunately, most of the prescribed anti-ulcer drugs generate various side effects. In this scenario, we could consider morin as a safe herbal potential agent against IND-gastropathy and rationalize its action systematically. Rats were pretreated with morin for 30 min followed by IND (48 mgkg(-1)) administration for 4 h. The anti-ulcerogenic nature of morin was assessed by morphological and histological analysis. Its effects on the inflammatory (MPO, cytokines, adhesion molecules), ulcer-healing (COXs, PGE(2)), and signaling parameters (NF-κB and apoptotic signaling) were assessed by biochemical, RP-HPLC, immunoblots, IHC, RT-PCR, and ELISA at the time points of their maximal changes due to IND administration. IND induced NF-κB and apoptotic signaling in rat's gastric mucosa. These increased proinflammatory responses, but reduced the antioxidant enzymes and other protective factors. Morin reversed all the adverse effects to prevent IND-induced gastric ulceration in a PGE2 independent manner. Also, it did not affect the absorption and/or primary pharmacological activity of IND. The gastroprotective action of morin is primarily attributed to its potent antioxidant nature that also helps in controlling several IND-induced inflammatory responses. For the first time, the study reveals a mechanistic basis of morin mediated protective action against IND-induced gastropathy. As morin is a naturally abundant safe antioxidant, future detailed pharmacokinetic and pharmacodynamic studies are expected to establish it as a gastroprotective agent. Copyright © 2015 Elsevier B.V.

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.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used for the treatment of inflammatory diseases. However, constant use of NSAID may lead to some side effects like gastrointestinal ulcers, bleeding and renal disorders. This study evaluates analgesic and anti-inflammatory activities of Lactobacillus rhamnosus in female Wistar rats. Diclofenac sodium was used as a standard drug for comparison. L. rhamnosus, drugs and vehicle were administered orally. Acetic acid-induced writhing test and carrageenan-induced paw edema model were used for evaluation. Paw edema and number of writhes were measured subsequently. Pro-inflammatory (interleukin (IL)-6, IL-1β, tumor necrosis factor (TNF)-α and IL-17) and anti-inflammatory (IL-4 and IL-10) cytokines were estimated in serum after 24 h. Results showed that L. rhamnosus significantly decreased the paw thickness at t=24 h by 28.66 % while drug decreased by 19.33 %. Also, L. rhamnosus treatment and standard drug showed a protection of 66.66 % and 41.66 %, respectively. L. rhamnosus and diclofenac sodium treatment significantly down-regulated pro-inflammatory and up-regulated anti-inflammatory cytokines at prhamnosus was more pronounced in comparison to diclofenac sodium. The present study clearly suggests that L. rhamnosus suppressed carrageenan-induced paw edema after second phase and decreased the acetic acid-induced writhings. It ameliorated the inflammatory pathways by down-regulating pro-inflammatory cytokines. However, additional clinical investigations are needed to prove the efficacy of L. rhamnosus in treatment/management of inflammatory joint diseases.

Background Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used pharmaceutical agents worldwide. NSAIDs are considered nephrotoxic and should therefore be used with caution or be avoided completely in high risk patients, such as chronic kidney disease (CKD) patients. Objective This study aimed to investigate the prescribing of NSAIDs in CKD patients in order to generate awareness and improve the outcome of these patients. Setting The study was conducted using medicine claims data in the private health sector of South Africa. Method A descriptive, quantitative study was performed, using retrospective data obtained from a Pharmaceutical Benefit Management company. Data from 1 January 2009 to 31 December 2013 were analysed. The study population consisted of all patients with an ICD-10 code for a CKD (N18), in association with a paid claim for an NSAID. Main outcome measure The stratification of NSAID prescribing volume among the CKD population in terms of gender, age, NSAID type, dosage and prescriber type. Results The prescribing of NSAIDs in CKD patients varied between 26 and 40 % over the 5 year study period. No association between gender and CKD patients who received NSAIDs versus those who did not was found, with p > 0.05 and Cramer's V < 0.1 for each year of the study. The association between age groups and CKD patients who received NSAIDs versus those who did not was statistically significant, but practically weak (p < 0.05; Cramer's V ≥ 0.1). Most NSAID prescriptions (52-63 %) were for patients aged 35-64 years. Diclofenac (34.25 %) was the single most frequently prescribed NSAID, but the COX-2-inhibitors (celecoxib, meloxicam and etoricoxib) were the preferred NSAID class to be prescribed. The majority (61.6 %) of the NSAIDs were prescribed by general medical practitioners in dosages meeting and even exceeding the recommended daily dosage of patients with normal kidney function. Conclusions Even though NSAIDs are

BACKGROUND Nonsteroidal anti-inflammatory drugs (NSAIDs) and analgesics are the most commonly used drugs and are increasingly available over-the-counter (OTC). In certain groups of patients, including kidney transplant recipients, their use may be complicated by adverse effects or drug interactions. The aim of our study was to assess the causes and frequency of OTC NSAIDs or analgesics use, as well as the awareness of related side effects. MATERIAL AND METHODS We enrolled 94 randomly selected kidney transplant recipients, who represented 5% of all kidney transplant recipients at our center. An anonymous survey consisting of 23 multiple-choice questions was administered voluntarily and anonymously. RESULTS In all, 63% of study patients confirmed taking the OTC painkillers; 22% of these patients took these drugs at least several times a week, and 4% took these drugs daily. For 38% of the study kidney transplant recipients, NSAIDs or analgesics were reported to be the only way to manage their pain. In addition, 30% of study patients were unaware of the risks associated with these drugs, despite the fact that 89% of the study patients consider physicians the best source of information. CONCLUSIONS Our study found that 63% of kidney transplant recipients regularly took OTC painkillers and 30% were unaware of the potential adverse effects. This necessitates continuous, ongoing education of kidney transplant recipients about the risks of OTC NSAIDs or analgesics use.

Conservative calculations estimate that approximately 107,000 patients are hospitalized annually for nonsteroidal anti-inflammatory drug (NSAID)-related gastrointestinal (GI) complications and at least 16,500 NSAID-related deaths occur each year among arthritis patients alone. The figures for all NSAID users would be overwhelming, yet the scope of this problem is generally under-appreciated. The Arthritis, Rheumatism, and Aging Medical Information System (ARAMIS) Post-Marketing Surveillance Program (PMS) has prospectively followed patient status and outcomes, drug side effects, and the economic impact of illness for >11,000 arthritis patients at 8 participating institutions in the United States and Canada. Analysis of these data indicates that: (1) osteoarthritis (OA) and rheumatoid arthritis (RA) patients are 2.5-5.5 times more likely than the general population to be hospitalized for NSAID-related GI events; (2) the absolute risk for serious NSAID-related GI toxicity remains constant and the cumulative risk increases over time; (3) there are no reliable warning signals- >80% of patients with serious GI complications had no prior GI symptoms; (4) independent risk factors for serious GI events were age, prednisone use, NSAID dose, disability level, and previous NSAID-induced GI symptoms; and (5) antacids and H2 antagonists do not prevent NSAID-induced gastric ulcers, and high-risk NSAID users who take gastro-protective drugs are more likely to have serious GI complications than patients not taking such medications. Currently, limiting NSAID use is the only way to decrease the risk of NSAID-related GI events. Ongoing ARAMIS research is aimed at developing a simple point-score system for estimating individual risks of developing serious NSAID-related GI complications.

The aim of this study was to describe the clinical and evolutive characteristics of gastroduodenal bleeding occurring in patients receiving nonsteroidal anti-inflammatory (NSAI) drugs, containing salicylates or not, and to determine the relative toxicity of the NSAI drugs without salicylates. Eight hundred and fourty-five consecutive patients with upper gastrointestinal bleeding related to endoscopically proven peptic ulcer or gastroduodenal erosions were admitted between 1983 and June 1987 to an intensive care unit for digestive tract hemorrhage. Of these, 267 were using anti-inflammatory drugs; 151 (56 p. 100) were taking NSAI drugs other than salicylates, 97 salicylates (36 p. 100) and 10, steroids (4 p. 100). Patients taking nonsteroidal drugs without or with salicylates were compared with patients bleeding from gastroduodenal ulcer or erosion not receiving anti-inflammatory therapy. Patients receiving nonsteroidal drugs not containing salicylates were older (70 p. 100 over 65 years of age vs 46 p. 100, p less than 0.001) and the proportion of female patients was greater (54 p. 100 vs 33 p. 100, p less than 0.001) than in the other group. No significant difference was observed with regard to the following parameters: percentage of gastric lesions, concomitant anticoagulant therapy, need for surgical hemostasis, or mortality. Patients taking aspirin had more gastric lesions (75 p. 100 vs 64 p. 100, p less than 0.05) and less need for surgical hemostasis (7 p. 100 vs 15 p. 100, p less than 0.05); the other parameters did not differ. NSAI drugs other than salicylates were taken more often for osteoarthritis than salicylates (33.6 p. 100 vs 17.4 p. 100, p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Delivery of sufficient amounts of therapeutic drugs into the eye is often a challenging task. In this study, ultrasound application (frequencies of 400 KHz to 1 MHz, intensities of 0.3-1.0 W/cm(2) and exposure duration of 5 min) was investigated to overcome the barrier properties of cornea, which is a typical route for topical administration of ophthalmic drugs. Permeability of ophthalmic drugs, tobramycin and dexamethasone and sodium fluorescein, a drug-mimicking compound, was studied in ultrasound- and sham-treated rabbit corneas in vitro using a standard diffusion cell setup. Light microscopy observations were used to determine ultrasound-induced structural changes in the cornea. For tobramycin, an increase in permeability for ultrasound- and sham-treated corneas was not statistically significant. Increase of 46%-126% and 32%-109% in corneal permeability was observed for sodium fluorescein and dexamethasone, respectively, with statistical significance (p anti-inflammatory ocular drug dexamethasone. Future investigations are needed to determine the effectiveness and safety of this application in in vivo long-term survival studies.

Nonsteroidal anti-inflammatory drugs, low-dose aspirin, non-aspirin antiplatelet agents, anticoagulants, selective serotonin reuptake inhibitors and corticosteroids increase the risk of gastroduodenal bleeding. To determine in a retrospective cohort study the contribution of Helicobacter pylori infection to the risk of peptic ulcer bleeding in patients taking these drugs. Among patients with peptic ulcer disease diagnosed by endoscopy from 01/2004 to 12/2014 (N = 1719, 60% males, age 65.8 ± 14.5), 56.9% had peptic ulcer bleeding (cases) and 43.1% uncomplicated peptic ulcer disease (controls). Demographics, intake of nonsteroidal anti-inflammatory drugs, aspirin, non-aspirin antiplatelet agents, anticoagulants, selective serotonin reuptake inhibitors, proton pump inhibitors and corticosteroids were documented. H. pylori status was determined by histology, rapid urease test or serology. Adjusted odds ratios (OR) were estimated by logistic regression analysis. Helicobacter pylori infection increased the risk of peptic ulcer bleeding in nonsteroidal anti-inflammatory drug and aspirin users (OR = 2.91, 95% CI = 1.71-4.98 and OR = 2.23, 95% CI = 1.52-3.28, respectively), but not in patients on anticoagulants, selective serotonin reuptake inhibitor or corticosteroid therapy. H. pylori-positive status substantially increased the risk of peptic ulcer bleeding in patients on non-aspirin antiplatelet agents (OR = 4.37, 95% CI = 1.28-14.99), concomitant aspirin/nonsteroidal anti-inflammatory drug intake (OR = 5.85, 95% CI = 1.68-20.36) and combined antiplatelet therapy (OR = 8.43, 95% CI = 1.09-65.17). After further adjustment for proton pump inhibitor intake, H. pylori infection was still a risk factor for peptic ulcer bleeding in nonsteroidal anti-inflammatory drug and aspirin users. Helicobacter pylori infection increases the risk of peptic ulcer bleeding in peptic ulcer disease patients on nonsteroidal anti-inflammatory drugs, aspirin and non

Full Text Available Patients with osteoarthritis (OA, a condition characterized by cartilage degradation, are often treated with steroids, nonsteroidal anti-inflammatory drugs (NSAIDs, and cyclooxygenase-2 (COX-2 selective NSAIDs. Due to their inhibition of the inflammatory cascade, the drugs affect the balance of matrix metalloproteinases (MMPs and inflammatory cytokines, resulting in preservation of extracellular matrix (ECM. To compare the effects of these treatments on chondrocyte metabolism, TNF-α was incubated with cultured chondrocytes to mimic a proinflammatory environment with increasing production of MMP-1 and prostaglandin E2 (PGE2. The chondrocytes were then treated with either a steroid (prednisone, a nonspecific COX inhibitor NSAID (piroxicam, or a COX-2 selective NSAID (celecoxib. Both prednisone and celecoxib decreased MMP-1 and PGE-2 production while the nonspecific piroxicam decreased only the latter. Both prednisone and celecoxib decreased gene expression of MMP-1 and increased expression of aggrecan. Increased gene expression of type II collagen was also noted with celecoxib. The nonspecific piroxicam did not show these effects. The efficacy of celecoxib in vivo was investigated using a posttraumatic OA (PTOA mouse model. In vivo, celecoxib increases aggrecan synthesis and suppresses MMP-1. In conclusion, this study demonstrates that celecoxib and steroids exert similar effects on MMP-1 and PGE2 production in vitro and that celecoxib may demonstrate beneficial effects on anabolic metabolism in vivo.

Animal oils and fats from the fishes Electrophorus electricus and Potamotrygon motoro, the reptiles Boa constrictor, Chelonoidis denticulata (Geochelone denticulata) and Melanosuchus niger and the riverine dolphin Inia geoffrensis are used as anti-inflammatory agents in the Peruvian Amazon. The aim of the study was to assess the topic anti-inflammatory effect of the oils/fats as well as to evaluate its antimicrobial activity and fatty acid composition. The oils/fats were purchased from a traditional store at the Iquitos market of Belen, Peru. The topic anti-inflammatory effect was evaluated by the mice ear edema induced by arachidonic acid (AA) and 12-O-tetradecanoylphorbol-13-acetate (TPA) at the dose of 3mg oil/ear. Indomethacine and nimesulide were used as reference anti-inflammatory drugs. The application resembles the traditional topical use of the oils. The antimicrobial effect of the oils/fats was assessed by the microdilution test against reference strains of Escherichia coli, Staphylococcus aureus and Salmonella enteritidis. The fatty acid composition of the oils/fats (as methyl esters) was determined by GC and GC-MS analysis after saponification. All oils/fats showed topic anti-inflammatory activity, with better effect in the TPA-induced mice ear edema assay. The most active drugs were Potamotrygon motoro, Melanosuchus niger and Geochelone denticulata. In the AA-induced assay, the best activity was found for Potamotrygon motoro and Electrophorus electricus oil. The oil of Electrophorus electricus also showed a weak antimicrobial effect with MIC values of 250 µg/mL against Escherichia coli ATCC 25922 and Salmonella enteritidis-MI. The main fatty acids in the oils were oleic, palmitic and linoleic acids. Topical application of all the oils/fats investigated showed anti-inflammatory activity in the mice ear edema assay. The effect can be related with the identity and composition of the fatty acids in the samples. This study gives support to the traditional

Nonsteroidal Anti-Inflammatory Drug Hypersensitivity in Preschool Children

Full Text Available Although extensively studied in adults, nonsteroidal anti-inflammatory drug (NSAID hypersensitivity in children, especially in young children, remains poorly defined. Pediatricians, prescribing antipyretics for children, rarely encounter significant problems, but the few epidemiologic studies performed show conflicting results. Although it is clear that some patients with acetylsalicylic acid (ASA-sensitive asthma have their clinical onset of disease in childhood and bronchoconstriction after ASA challenge is seen in 0 to 22% of asthmatic children so challenged, ibuprofen at antipyretic doses may cause acute respiratory problems only in a very small number of mild to moderate asthmatics. The recently elucidated mechanism of action of acetaminophen may explain some occurrences of adverse reactions in patients with cross-reactive NSAID hypersensitivity on the basis of its inhibitory activity on the newly described enzyme, cyclooxygenase (COX-3. This nonspecific sensitivity to inhibition of COX is most likely genetically determined and shows a remarkable association with atopic disease even in the very young age group and possibly an increased predilection in specific ethnic groups. This review summarizes state-of-the-art published data on NSAID hypersensitivity in preschool children.

2006-08-24

Chitosan, a polymer derived from chitin, has been used for nasal drug delivery because of its biocompatibility, biodegradability and bioadhesiveness. Theophylline is a drug that reduces the inflammatory effects of allergic asthma but is difficult to administer at an appropriate dosage without causing adverse side effects. It was hypothesized that adsorption of theophylline to chitosan nanoparticles modified by the addition of thiol groups would improve theophylline absorption by the bronchial epithelium and enhance its anti-inflammatory effects. We sought to develop an improved drug-delivery matrix for theophylline based on thiolated chitosan, and to investigate whether thiolated chitosan nanoparticles (TCNs) can enhance theophylline's capacity to alleviate allergic asthma. A mouse model of allergic asthma was used to test the effects of theophylline in vivo. BALB/c mice were sensitized to ovalbumin (OVA) and OVA-challenged to produce an inflammatory allergic condition. They were then treated intranasally with theophylline alone, chitosan nanoparticles alone or theophylline adsorbed to TCNs. The effects of theophylline on cellular infiltration in bronchoalveolar lavage (BAL) fluid, histopathology of lung sections, and apoptosis of lung cells were investigated to determine the effectiveness of TCNs as a drug-delivery vehicle for theophylline. Theophylline alone exerts a moderate anti-inflammatory effect, as evidenced by the decrease in eosinophils in BAL fluid, the reduction of bronchial damage, inhibition of mucus hypersecretion and increased apoptosis of lung cells. The effects of theophylline were significantly enhanced when the drug was delivered by TCNs. Intranasal delivery of theophylline complexed with TCNs augmented the anti-inflammatory effects of the drug compared to theophylline administered alone in a mouse model of allergic asthma. The beneficial effects of theophylline in treating asthma may be enhanced through the use of this novel drug delivery

Full Text Available Abstract Background Chitosan, a polymer derived from chitin, has been used for nasal drug delivery because of its biocompatibility, biodegradability and bioadhesiveness. Theophylline is a drug that reduces the inflammatory effects of allergic asthma but is difficult to administer at an appropriate dosage without causing adverse side effects. It was hypothesized that adsorption of theophylline to chitosan nanoparticles modified by the addition of thiol groups would improve theophylline absorption by the bronchial epithelium and enhance its anti-inflammatory effects. Objectives We sought to develop an improved drug-delivery matrix for theophylline based on thiolated chitosan, and to investigate whether thiolated chitosan nanoparticles (TCNs can enhance theophylline's capacity to alleviate allergic asthma. Methods A mouse model of allergic asthma was used to test the effects of theophylline in vivo. BALB/c mice were sensitized to ovalbumin (OVA and OVA-challenged to produce an inflammatory allergic condition. They were then treated intranasally with theophylline alone, chitosan nanoparticles alone or theophylline adsorbed to TCNs. The effects of theophylline on cellular infiltration in bronchoalveolar lavage (BAL fluid, histopathology of lung sections, and apoptosis of lung cells were investigated to determine the effectiveness of TCNs as a drug-delivery vehicle for theophylline. Results Theophylline alone exerts a moderate anti-inflammatory effect, as evidenced by the decrease in eosinophils in BAL fluid, the reduction of bronchial damage, inhibition of mucus hypersecretion and increased apoptosis of lung cells. The effects of theophylline were significantly enhanced when the drug was delivered by TCNs. Conclusion Intranasal delivery of theophylline complexed with TCNs augmented the anti-inflammatory effects of the drug compared to theophylline administered alone in a mouse model of allergic asthma.

Full Text Available Clinical Relevance. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs including aspirin are of intensive use nowadays. These drugs exert their activity via the metabolism of arachidonic acid (AA by cyclooxygenase inhibition. Though beneficial for health in some instances, both unspecific and specific cyclooxygenase inhibitor activity interfere with AA metabolism producing also proinflammatory lipids that may promote cancer. Materials and Methods. This review is based on available literature on clinical uses, biochemical investigations, molecular medicine, pharmacology, toxicity, and epidemiology-clinical studies on NSAIDs and other drugs that may be used accordingly, which was collected from electronic (SciFinder, Medline, Science Direct, and ACS among others and library searches of books and journals. Results. Relevant literature supports the notion that NDSAID use may also promote proinflammatory biochemical events that are also related to precancerous predisposition. Several agents are proposed that may be employed in immediate future to supplement and optimize treatment with NSAIDs. In this way serious side effects arising from promotion of inflammation and cancer, especially in chronic NSAID users and high risk groups of patients, could be avoided.

Evaluation of Anti-Inflammatory Drug-Conjugated Silicon Quantum Dots: Their Cytotoxicity and Biological Effect

2013-01-01

Full Text Available Silicon quantum dots (Si-QDs have great potential for biomedical applications, including their use as biological fluorescent markers and carriers for drug delivery systems. Biologically inert Si-QDs are less toxic than conventional cadmium-based QDs, and can modify the surface of the Si-QD with covalent bond. We synthesized water-soluble alminoprofen-conjugated Si-QDs (Ap-Si. Alminoprofen is a non-steroid anti-inflammatory drug (NSAID used as an analgesic for rheumatism. Our results showed that the “silicon drug” is less toxic than the control Si-QD and the original drug. These phenomena indicate that the condensed surface integration of ligand/receptor-type drugs might reduce the adverse interaction between the cells and drug molecules. In addition, the medicinal effect of the Si-QDs (i.e., the inhibition of COX-2 enzyme was maintained compared to that of the original drug. The same drug effect is related to the integration ratio of original drugs, which might control the binding interaction between COX-2 and the silicon drug. We conclude that drug conjugation with biocompatible Si-QDs is a potential method for functional pharmaceutical drug development.

Full Text Available Different chemotypes are described as anti-inflammatory. Among them the N-acylhydrazones (NAH are highlighted by their privileged structure nature, being present in several anti-inflammatory drug-candidates. In this paper a series of functionalized 3-aminothiophene-2-acylhydrazone derivatives 5a–i were designed, synthesized and bioassayed. These new derivatives showed great anti-inflammatory and analgesic potency and efficacy. Compounds 5a and 5d stand out in this respect, and were also active in CFA-induced arthritis in rats. After daily treatment for seven days with 5a and 5d (50 µmol/Kg, by oral administration, these compounds were not renal or hepatotoxic nor immunosuppressive. Compounds 5a and 5d also displayed good drug-scores and low risk toxicity calculated in silico using the program OSIRIS Property Explorer.

Chronic inflammatory disorders such as rheumatoid arthritis are characterized by excessive pro-inflammatory or "M1" activation of macrophages, the primary cells of the innate immune system. Current treatments include delivery of glucocorticoids (e.g. dexamethasone - Dex), which reduce pro-inflammatory M1 behaviour in macrophages. However, these treatments have many off-target effects on cells other than macrophages, resulting in broad immunosuppression. To limit such side effects, drug-incorporated nano- and microparticles may be used to selectively target macrophages via phagocytosis, because of their roles as highly effective phagocytes in the body. In this study, surface-modified nanodiamond (ND) was explored as a platform for the delivery of dexamethasone to macrophages because of ND's rich surface chemistry, which contributes to ND's high potential as a versatile drug delivery platform. After finding that octadecylamine-functionalized nanodiamond (ND-ODA) enhanced adsorption of Dex compared to carboxylated ND, the effects of Dex, ND-ODA, and Dex-adsorbed ND-ODA on primary human macrophage gene expression were characterized. Surprisingly, even in the absence of Dex, ND-ODA had strong anti-inflammatory effects, as determined by multiplex gene expression via NanoString and by protein secretion analysis via ELISA. ND-ODA also inhibited expression of M2a markers yet increased the expression of M2c markers and phagocytic receptors. Interestingly, the adsorption of Dex to ND-ODA further increased some anti-inflammatory effects, but abrogated the effect on phagocytic receptors, compared to its individual components. Overall, the ability of ND-ODA to promote anti-inflammatory and pro-phagocytic behaviour in macrophages, even in the absence of loaded drugs, suggests its potential for use as an anti-inflammatory therapeutic to directly target macrophages through phagocytosis.

Pathogenesis of Nonsteroidal Anti-Inflammatory Drug Gastropathy: Clues to Preventative Therapy

Full Text Available Gastric ulceration and bleeding are major impediments to the chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs. The development of effective therapies for prevention of these adverse effects requires better understanding of their pathogenesis. Several features of NSAIDs contribute to the development of damage in the stomach, including the topical irritant effects of these drugs on the epithelium, impairment of the barrier properties of the mucosa, suppression of gastric prostaglandin synthesis, reduction of gastric mucosal blood flow and interference with the repair of superficial injury. The presence of acid in the lumen of the stomach also contributes to the pathogenesis of NSAID-induced ulcers and bleeding in a number of ways. Acid impairs the restitution process, interferes with hemostasis and can inactivate several growth factors that are important in mucosal integrity and repair. Profound suppression of gastric acid secretion has been shown to be effective in preventing NSAID-induced ulceration. There is a strong possibility that new NSAIDs entering the market will have greatly reduced toxicity in the gastrointestinal tract.

Roth, Sanford H

2012-05-07

Despite well known complications, oral nonsteroidal anti-inflammatory drugs (NSAIDs) remain the most commonly prescribed medications in the US for musculoskeletal disorders such as osteoarthritis. Although there has been a recent focus on the cardiovascular and renal complications associated with these agents, NSAID gastropathy continues to be a particular concern in many patients, especially those at increased risk for serious adverse events, including the elderly. Complicating the diagnosis of NSAID gastropathy is its silent course, which, up to half of the time, is asymptomatic. Several strategies are currently employed by physicians to mitigate the risk of serious gastrointestinal events. These include either addition of a proton pump inhibitor to current nonselective NSAID therapy or the use of a cyclo-oxygenase-2-selective NSAID. Although these agents are effective at mitigating the overall risk of gastrointestinal adverse events, they fail to address NSAID-related cardiovascular and renal risks. Due to their reduced systemic absorption, topical NSAIDs may present a viable option for patients at increased risk for serious NSAID-related adverse events, including gastropathy.

and IL-10 is provoked by exercise and exerts direct anti-inflammatory effects by an inhibition of TNF-α and by stimulating IL-1ra, thereby limiting IL-1β signalling. Moreover, muscle-derived IL-6 appears to have direct anti-inflammatory effects and serves as a mechanism to improve glucose tolerance....... In addition, indirect anti-inflammatory effects of long-term exercise are mediated via improvements in body composition. CONCLUSION: Physical activity represents a natural, strong anti-inflammatory strategy with minor side effects and should be integrated in the management of patients with cardiometabolic...

Full Text Available Abstract Background Antidepressants are heavily prescribed drugs and have been shown to affect inflammatory signals. We examined whether these have anti-inflammatory properties in animal models of septic shock and allergic asthma. We also analysed whether antidepressants act directly on peripheral cell types that participate in the inflammatory response in these diseases. Methods The antidepressants desipramine and fluoxetine were compared in vivo to the glucocorticoid prednisolone, an anti-inflammatory drug of reference. In a murine model of lipopolysaccharides (LPS-induced septic shock, animals received the drugs either before or after injection of LPS. Circulating levels of tumour necrosis factor (TNF-α and mortality rate were measured. In ovalbumin-sensitized rats, the effect of drug treatment on lung inflammation was assessed by counting leukocytes in bronchoalveolar lavages. Bronchial hyperreactivity was measured using barometric plethysmography. In vitro production of TNF-α and Regulated upon Activation, Normal T cell Expressed and presumably Secreted (RANTES from activated monocytes and lung epithelial cells, respectively, was analysed by immunoassays. Reporter gene assays were used to measure the effect of antidepressants on the activity of nuclear factor-κB and activator protein-1 which are involved in the control of TNF-α and RANTES expression. Results In the septic shock model, all three drugs given preventively markedly decreased circulating levels of TNF-α and mortality (50% mortality in fluoxetine treated group, 30% in desipramine and prednisolone treated groups versus 90% in controls. In the curative trial, antidepressants had no statistically significant effect, while prednisolone still decreased mortality (60% mortality versus 95% in controls. In ovalbumin-sensitized rats, the three drugs decreased lung inflammation, albeit to different degrees. Prednisolone and fluoxetine reduced the number of macrophages, lymphocytes

COX-independent mechanisms of cancer chemoprevention by anti-inflammatory drugs

Evrim eGurpinar

2013-07-01

Full Text Available Epidemiological and clinical studies suggest that non-steroidal anti-inflammatory drugs (NSAIDs, including cyclooxygenase (COX-2 selective inhibitors, reduce the risk of developing cancer. Experimental studies in human cancer cell lines and rodent models of carcinogenesis support these observations by providing strong evidence for the antineoplastic properties of NSAIDs. The involvement of COX-2 in tumorigenesis and its overexpression in various cancer tissues suggest that inhibition of COX-2 is responsible for the chemopreventive efficacy of these agents. However, the precise mechanisms by which NSAIDs exert their antiproliferative effects are still a matter of debate. Numerous other studies have shown that NSAIDs can act through COX-independent mechanisms. This review provides a detailed description of the major COX-independent molecular targets of NSAIDs and discusses how these targets may be involved in their anticancer effects. Toxicities resulting from COX inhibition and the suppression of prostaglandin synthesis preclude the long-term use of NSAIDs for cancer chemoprevention. Furthermore, chemopreventive efficacy is incomplete and treatment often leads to the development of resistance. Identification of alternative NSAID targets and elucidation of the biochemical processes by which they inhibit tumor growth could lead to the development of safer and more efficacious drugs for cancer chemoprevention.

Full Text Available PURPOSE: Evaluate the cardiovascular and hematological effects produced by chronic treatment with two dosis of etoricoxib in Wistar normotensive rats. METHODS: Thirty rats have been used and divided into one control group and two etoricoxib (10mg/kg and 30mg/kg treatments groups for 60 days. The mean arterial pressure (MAP was taken during the whole experimental period and at the end of this period, under anesthesia blood samples were taken, and further the withdrawn of the aorta, heart, brain, liver, and kidneys for the anatomopathologic study. RESULTS: The treatment with etoricoxib (30mg/Kg produced a significant increase of the MAP from the 28th day of the experiment and from the platelets when compared to the control group and to the group treated with 10mg/Kg, besides producing a highly significant difference in hematocrit and in the red blood cells in relation to the control group. On the other hand the treatment with etoricoxib has not caused histopathological changes when compared to the control. CONCLUSION: These data show that the chronic treatment with etoricoxib leads to increase of the MAP, and to important hematological changes which seem to be associated to the hemoconcentration although not producing anatomopathological significant changes.OBJETIVO: Avaliar os efeitos cardiovasculares e hematológicos produzidos pelo tratamento crônico com duas doses de etoricoxib em ratos Wistar normotensos.

Full Text Available The aim of this study was to investigate the anti-inflammatory effects of Ursodeoxycholic acid (UDCA in lipopolysaccharide (LPS-stimulated RAW 264.7 macrophages.We induced an inflammatory process in RAW 264.7 macrophages using LPS. The anti-inflammatory effects of UDCA on LPS-stimulated RAW 264.7 macrophages were analyzed using nitric oxide (NO. Pro-inflammatory and anti-inflammatory cytokines were analyzed by quantitative real time polymerase chain reaction (qRT-PCR and enzyme-linked immunosorbent assay (ELISA. The phosphorylations of extracellular signal-regulated kinase (ERK, c-Jun N-terminal kinase (JNK, and p38 in mitogen-activated protein kinase (MAPK signaling pathways and nuclear factor kappa-light polypeptide gene enhancer in B-cells inhibitor, alpha (IκBα signaling pathways were evaluated by western blot assays.UDCA decreased the LPS-stimulated release of the inflammatory mediator NO. UDCA also decreased the pro-inflammatory cytokines tumor necrosis factor-α (TNF-α, interleukin 1-α (IL-1α, interleukin 1-β (IL-1β, and interleukin 6 (IL-6 in mRNA and protein levels. In addition, UDCA increased an anti-inflammatory cytokine interleukin 10 (IL-10 in the LPS-stimulated RAW 264.7 macrophages. UDCA inhibited the expression of inflammatory transcription factor nuclear factor kappa B (NF-κB in LPS-stimulated RAW 264.7 macrophages. Furthermore, UDCA suppressed the phosphorylation of ERK, JNK, and p38 signals related to inflammatory pathways. In addition, the phosphorylation of IκBα, the inhibitor of NF-κB, also inhibited by UDCA.UDCA inhibits the pro-inflammatory responses by LPS in RAW 264.7 macrophages. UDCA also suppresses the phosphorylation by LPS on ERK, JNK, and p38 in MAPKs and NF-κB pathway. These results suggest that UDCA can serve as a useful anti-inflammatory drug.

Quality of Life in Arthritis Patients Using Nonsteroidal Anti-Inflammatory Drugs

Ingela Wiklund

1999-01-01

Full Text Available Arthritis is a painful and disabling condition. To suppress the pain and the inflammatory process, patients are often chronic nonsteroidal anti-inflammatory drug (NSAID users. Chronic use of NSAIDs may induce peptic ulcer, dyspeptic problems and heartburn. Therefore, these patients are often provided with treatment to relieve and/or protect against gastrointestinal problems. Rheumatic disorders also affect a range of health-related quality of life domains. In one study, patients with NSAID-associated gastroduodenal lesions complained about lack of energy, sleep disturbances, emotional distress and social isolation in addition to pain and mobility limitations. The degree of distress and dysfunction differed markedly from scores in an unselected population. Clinical trial data suggest that acid-suppressing therapy with omeprazole is superior to therapy with misoprostol and ranitidine in healing gastroduodenal lesions and preventing abdominal pain, heartburn and indigestion symptoms during continued NSAID treatment. Because arthritic patients are severely incapacitated by their condition regarding most aspects of health-related quality of life, it is important to offer a treatment that is effective in healing and preventing NSAID-induced ulcers and gastrointestinal symptoms during continued NSAID treatment without further compromising the patients’ quality of life. Treatment with omeprazole once daily has been shown to be superior to that with ranitidine and misoprostol in this respect.

Full Text Available The synthesis method of layered double hydroxides (LDHs determines nanoparticles’ performance in biomedical applications. In this study, hydrothermal treatment as an important synthesis technique has been examined for its influence on the physicochemical properties and the drug release rate from drug-containing LDHs. We synthesised MgAl–LDHs intercalated with non-steroidal anti-inflammatory drugs (i.e., naproxen, diclofenac and ibuprofen using a co-precipitation method with or without hydrothermal treatment (150 °C, 4 h. After being hydrothermally treated, LDH–drug crystallites increased in particle size and crystallinity, but did not change in the interlayer anion orientation, gallery height and chemical composition. The drug release patterns of all studied LDH–drug hybrids were biphasic and sustained. LDHs loaded with diclofenac had a quicker drug release rate compared with those with naproxen and ibuprofen, and the drug release from the hydrothermally-treated LDH–drug was slower than the freshly precipitated LDH–drug. These results suggest that the drug release of LDH–drugs is influenced by the crystallite size of LDHs, which can be controlled by hydrothermal treatment, as well as by the drug molecular physicochemical properties.

The electrocatalytic oxidation of several anti-inflammatory drugs (mefenamic acid, diclofenac and indomethacin) was investigated on a nickel hydroxide-modified nickel (NHMN) electrode in alkaline solution. This oxidation process and its kinetics were studied using cyclic voltammetry, chronoamperometry, and electrochemical impedance spectroscopy techniques. Voltammetric studies indicated that in the presence of drugs, the anodic peak current of low-valence nickel species increases, followed by a decrease in the corresponding cathodic current. This pattern indicates that drugs were oxidized on the redox mediator immobilized on the electrode surface via an electrocatalytic mechanism. A mechanism based on the electrochemical generation of Ni(III) active sites and their subsequent consumption by drugs was also investigated. The corresponding rate law under the control of charge transfer was developed and kinetic parameters were derived. In this context, the charge-transfer resistance accessible both theoretically and through impedancemetry was used as a criterion. The rate constants of the catalytic oxidation of drugs and the electron-transfer coefficients are reported. A sensitive, simple and time-saving amperometric procedure was developed for the analysis of these drugs in bulk form and for the direct assay of tablets, using the NHMN electrode.

Buddleja globosa, known as "matico", is employed in Chile for wound healing. To validate the traditional use of the crude drug through in vivo and in vitro evaluation of the anti-inflammatory, analgesic and antioxidant properties of its extracts. Sequential hexane, dichloromethane, methanol and total methanol extracts were studied using bioguided fractionation. The following activities were investigated: analgesic (writhing test), oral and topic anti-inflammatory (paw- and ear-induced edema), free radical scavenging and antioxidant activities (1,1-diphenyl-2-picrylhydrazyl, DPPH, superoxide anion, lipid peroxidation and xanthine oxidase inhibition). Sodium naproxen, nimesulide, indomethacin were used as reference drugs for in vivo, quercetin and allopurinol for in vitro assays. A mixture of alpha- and beta-amyrins was isolated from the hexane extract that showed 41.2% of analgesic effect at 600 mg/kg, inhibited by 47.7 and 79.0% the arachidonic acid (AA) and 12-deoxyphorbol-13-decanoate (TPA)-induced inflammation at 3mg/20 microL/ear, respectively. A mixture of beta-sitosterol, stigmasterol, stigmastenol, stigmastanol and campesterol was isolated from the fraction CD4-N and beta-sitosterol-glycoside from the fraction CD5-N, reducing TPA-induced inflammation by 78.2 and 83.7% at 1mg/20 microL/ear, respectively. The fraction CD4-N at 300 mg/kg also showed analgesic activity (38.7%). The methanol extract at 600mg/kg per os showed anti-inflammatory effect (61.4%), topic anti-inflammatory (56.7% on TPA) and analgesic activity (38.5%). Verbascoside and luteolin-7-O-glucoside were the major components of the methanol extract; apigenin 7-O-glucoside was also detected. Inhibition of superoxide anion, lipoperoxidation, and DPPH bleaching effect was found in the methanol serial and global extracts. The present report demonstrate the analgesic and anti-inflammatory properties of Buddleja globosa and validate its use in Chilean traditional medicine.

Full Text Available Aim: The current study aimed to examine the effects of resistance exercise with concomitant consumption of high vs. low daily doses of non-steroidal anti-inflammatory drugs (NSAIDs on mitochondrial oxidative phosphorylation in skeletal muscle. As a secondary aim, we compared the effects of eccentric overload with conventional training.Methods: Twenty participants were randomized to either a group taking high doses (3 × 400 mg/day of ibuprofen (IBU; 27 ± 5 year; n = 11 or a group ingesting a low dose (1 × 75 mg/day of acetylsalicylic acid (ASA; 26 ± 4 year; n = 9 during 8 weeks of supervised knee extensor resistance training. Each of the subject's legs were randomized to complete the training program using either a flywheel (FW device emphasizing eccentric overload, or a traditional weight stack machine (WS. Maximal mitochondrial oxidative phosphorylation (CI+IIP from permeabilized skeletal muscle bundles was assessed using high-resolution respirometry. Citrate synthase (CS activity was assessed using spectrophotometric techniques and mitochondrial protein content using western blotting.Results: After training, CI+IIP decreased (P < 0.05 in both IBU (23% and ASA (29% with no difference across medical treatments. Although CI+IIP decreased in both legs, the decrease was greater (interaction p = 0.015 in WS (33%, p = 0.001 compared with FW (19%, p = 0.078. CS activity increased (p = 0.027 with resistance training, with no interactions with medical treatment or training modality. Protein expression of ULK1 increased with training in both groups (p < 0.001. The increase in quadriceps muscle volume was not correlated with changes in CI+IIP (R = 0.16.Conclusion: These results suggest that 8 weeks of resistance training with co-ingestion of anti-inflammatory drugs reduces mitochondrial function but increases mitochondrial content. The observed changes were not affected by higher doses of NSAIDs consumption, suggesting that the resistance training

Drug-drug interactions are relatively rarely reported to spontaneous reporting systems (SRSs) for adverse drug reactions. For this reason, the traditional approach for analysing SRS has major limitations for the detection of drug-drug interactions. We developed a method that may enable signalling of these possible interactions, which are often not explicitly reported, utilising reports of adverse drug reactions in data sets of SRS. As an example, the influence of concomitant use of diuretics and non-steroidal anti-inflammatory drugs (NSAIDs) on symptoms indicating a decreased efficacy of diuretics was examined using reports received by the Netherlands Pharmacovigilance Foundation Lareb. Reports received between 1 January 1990 and 1 January 1999 of patients older than 50 years were included in the study. Cases were defined as reports with symptoms indicating a decreased efficacy of diuretics, non-cases as all other reports. Exposure categories were the use of NSAIDs or diuretics versus the use of neither of these drugs. The influence of the combined use of both drugs was examined using logistic regression analysis. The odds ratio of the statistical interaction term of the combined use of both drugs was increased [adjusted odds ratio 2.0, 95% confidence interval (CI) 1.1-3.7], which may indicate an enhanced effect of concomitant drug use. The findings illustrate that spontaneous reporting systems have a potential for signal detection and the analysis of possible drug-drug interactions. The method described may enable a more active approach in the detection of drug-drug interactions after marketing.

Alcoholic extracts of the leaves of Ambrosia artemisiaefolia and Rhoeo spathacea have been investigated for anti-inflammatory activity using various experimental models of inflammation (croton oil ear oedema, carrageenan-induced edema, cotton pellet granuloma and formaldehyde induced arthritis) and the results compared with phenylbutazone and bethamethasone, standard anti-inflammatory drugs. These extracts at doses of 50, 100 and 150mg/kg of A. artemisiaefolia and R. spathacea, showed significant inhibition of acute oedema in rats and mice induced by the phlogistic agents, carrageenan and croton oil, in a dose-dependant manner. The ethanol extracts reduced cotton pellet granuloma and caused a statistically significant inhibitory effect on edema in the chronic model of formaldehyde arthritis in rats. Since Ambrosia artemisiaefolia and Rhoeo spathacea were found to be effective in both acute and chronic phases of inflammation they can be considered as general anti-inflammatory agents.

2018-04-05

Epimedium brevicornu Maxim has been used as a traditional herbal drug in China. In this study, the anti-inflammatory effects of E. brevicornu Maxim ethanol extract (EBME) were investigated in RAW264.7 macrophages and mice challenged with lipopolysaccharide (LPS). Results showed that EBME attenuated inflammation by decreasing the production of several proinflammatory mediators, such as nitric oxide (NO), prostaglandin (PG) E 2 , inducible nitric oxide synthase, and cyclooxygenase-2, in LPS-stimulated RAW264.7 macrophages. EBME increased the expression of heme oxygenase-1 (HO-1) and promoted the nuclear translocation of nuclear factor erythroid 2-related factor 2. The inhibitory effects of EBME on LPS-stimulated NO and PGE 2 expression were partially reversed by HO-1 inhibitor. EBME also elicited an anti-inflammatory effect by inhibiting the production of tumor necrosis factor-α, interleukin (IL)-1β, and IL-6 in LPS-induced peritonitis. Therefore, EBME exhibited anti-inflammatory effects in vitro and in vivo.

Approaches to the diagnosis and management of patients with a history of nonsteroidal anti-inflammatory drug-related urticaria and angioedema.

Kowalski, Marek L; Woessner, Katharine; Sanak, Marek

Nonsteroidal anti-inflammatory drug (NSAID)-induced urticarial and angioedema reactions are among the most commonly encountered drug hypersensitivity reactions in clinical practice. Three major clinical phenotypes of NSAID-induced acute skin reactions manifesting with angioedema, urticaria, or both have been distinguished: NSAID-exacerbated cutaneous disease, nonsteroidal anti-inflammatory drug-induced urticaria/angioedema (NIUA), and single NSAID-induced urticaria and angioedema. In some patients clinical history alone might be sufficient to establish the diagnosis of a specific type of NSAID hypersensitivity, whereas in other cases oral provocation challenges are necessary to confirm the diagnosis. Moreover, classification of the type of cutaneous reaction is critical for proper management. For example, in patients with single NSAID-induced reactions, chemically nonrelated COX-1 inhibitors can be safely used. However, there is cross-reactivity between the NSAIDs in patients with NSAID-exacerbated cutaneous disease and NIUA, and thus only use of selective COX-2 inhibitors can replace the culprit drug if the chronic treatment is necessary, although aspirin desensitization will allow for chronic treatment with NSAIDs in some patients with NIUA. In this review we present a practical clinical approach to the patient with NSAID-induced urticaria and angioedema. Copyright © 2015 American Academy of Allergy, Asthma & Immunology.

To evaluate the anti-oxidant and anti-inflammatory activity of leaf extracts and fractions of Mangifera indica in in vitro conditions. In vitro DPPH radical scavenging activity and lipoxygenase (LOX) inhibition assays were used to evaluate the anti-oxidant and anti-inflammatory activities respectively. Methanolic extract (MEMI), successive water extract (SWMI) and ethyl acetate fraction (EMEMI), n-butanol fraction (BMEMI) and water soluble fraction (WMEMI) of methanolic extract were evaluated along with respective reference standards. In in vitro DPPH radical scavenging activity, the MEMI, EMEMI and BMEMI have offered significant antioxidant activity with IC(50) values of 13.37, 3.55 and 14.19 μg/mL respectively. Gallic acid, a reference standard showed significant antioxidant activity with IC(50) value of 1.88 and found to be more potent compared to all the extracts and fractions. In in vitro LOX inhibition assay, the MEMI, EMEMI and BMEMI have showed significant inhibition of LOX enzyme activity with IC(50) values of 96.71, 63.21 and 107.44 μg/mL respectively. While, reference drug Indomethacin also offered significant inhibition against LOX enzyme activity with IC(50) of 57.75. Furthermore, MEMI was found to more potent than SWMI and among the fractions EMEMI was found to possess more potent antioxidant and anti-inflammatory activity. These findings suggest that the MEMI and EMEMI possess potent anti-oxidant and anti-inflammatory activities in in vitro conditions. Copyright © 2013 Hainan Medical College. Published by Elsevier B.V.

In this review the available evidences regarding the most frequently applied medication (peroral and transdermal non-steroidal anti-inflammatory agents) for the most frequent musculoskeletal complaints (regional pain syndromes) have been collected for the appropriate medical professionals who are most frequently faced with these conditions (general practitioners, rheumatologists, orthopedics, occupational and sports medicine experts). The special population at risk (with repeated and high energy overuse because of occupational or sport activities) and the pathology of their syndromes are identified. Mode of action, pharmacological properties of the non-steroidal anti-inflammatory drugs and the unwanted effects of their application especially in infants and elderly are highlighted. Recommendations of the general and specific pain management guidelines have been selected and listed in the review. Orv Hetil. 2017; 158(Suppl. 3): 3-30.

Alejo J Nevado-Holgado

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

Full Text Available Objective: To evaluate the anti-inflammatory and antipyretic potentials of artesunate in albino wistar mice and rats respectively. Methods: For the anti-inflammatory activity, artesunate (5 mg/kg was administered orally against egg albumin- and xylene-induced inflammation in mice using ibuprofen (50 mg/kg as standard drug. To assess antipyretic activity, artesunate (5 mg/kg was administered orally against amphetamine- and 2, 4-dinitrophenol-induced pyrexia in rats using ibuprofen (15 mg/ kg as standard drug. Results: The result showed that artesunate significantly (P < 0.001–0.010 reduced inflammation induced by egg albumin and xylene in a time-dependent manner. It also significantly (P < 0.001–0.050 and time-dependently reduced pyrexia induced by amphetamine and 2, 4-dinitrophenol. These reductions were similar to those produced by the standard drug ibuprofen, and thereby demonstrating that artesunate possesses antiinflammatory and antipyretic activities. Conclusions: These results further support the rationale for the use of artesunate in the treatment of malaria, a disease characterized by fever and inflammation and open up possibilities of its usefulness in other inflammatory and feverish diseases.

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

Science.gov (United States)

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

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.

Minimally invasive glucose biosensors with increased functional longevity form one of the most promising techniques for continuous glucose monitoring. In the present study, we developed a novel nanoengineered microsphere formulation comprising alginate microsphere glucose sensors and anti-inflammatory-drug-loaded alginate microspheres. The formulation was prepared and characterized for size, shape, in vitro drug release, biocompatibility, and in vivo acceptability. Glucose oxidase (GOx)- and Apo-GOx-based glucose sensors were prepared and characterized. Sensing was performed both in distilled water and simulated interstitial body fluid. Layer-by-layer self-assembly techniques were used for preventing drug and sensing chemistry release. Finally, in vivo studies, involving histopathologic examination of subcutaneous tissue surrounding the implanted sensors using Sprague-Dawley rats, were performed to test the suppression of inflammation and fibrosis associated with glucose sensor implantation. The drug formulation showed 100% drug release with in 30 days with zero-order release kinetics. The GOx-based sensors showed good enzyme retention and enzyme activity over a period of 1 month. Apo-GOx-based visible and near-infrared sensors showed good sensitivity and analytical response range of 0-50 mM glucose, with linear range up to 12 mM glucose concentration. In vitro cell line studies proved biocompatibility of the material used. Finally, both anti-inflammatory drugs were successful in controlling the implant-tissue interface by suppressing inflammation at the implant site. The incorporation of anti-inflammatory drug with glucose biosensors shows promise in improving sensor biocompatibility, thereby suggesting potential application of alginate microspheres as "smart tattoo" glucose sensors with increased functional longevity. © 2010 Diabetes Technology Society.

Pyrexia, algesia and inflammation are associated with several pathological conditions. Synthetic drugs available for the treatment of these conditions cause multiple unwanted effects. Several studies are ongoing worldwide to find natural healing agents with better safety profile. The current study was thus aimed at evaluating antipyretic, analgesic and anti-inflammatory activities of the methanolic extract of whole plant of V. betonicifolia (VBME). VBME was employed to assess antipyretic activity in yeast induced hyperthermia. Analgesic profile was ascertained in acetic acid induced writhing, hot plat and tail immersion test. Nevertheless, the anti-inflammatory activity was tested in carrageenan induced paw edema and histamine induced inflammatory tests. BALB/c mice were used at test doses of 100, 200 and 300 mg/kg body weight intra peritoneally (i.p). In yeast induced pyrexia, VBME demonstrated dose dependently (78.23%) protection at 300 mg/kg, similar to standard drug, paracetamol (90%) at 150 mg/kg i.p. VBME showed a dose dependent analgesia in various pain models i.e. acetic acid, hot plat and tail immersion having 78.90%, 69.96% and 68.58% protection respectively at 300 mg/kg. However, the analgesic action of VBME was completely antagonized by the injection of naloxone like opiate antagonists. Similarly carrageenan and histamine induces inflammation was significantly antagonized by VBME, 66.30% and 60.80% respectively at 300 mg/kg. It is concluded that VBME has marked antipyretic, analgesic and anti-inflammatory activities in various animal models and this strongly supports the ethnopharmacological uses of Viola betonicifolia as antipyretic, analgesic and anti-inflammatory plant.

We have hypothesized that etoricoxib premedication would reduce the need for additional opioids following orthopedic trauma surgery. A double blind, controlled study, conducted in King Fahd University Hospital, King Faisal University, Dammam, Kingdom of Saudi Arabia. After obtaining the approval of Research and Ethics Committee and written consent, 200 American Society of Anesthesiology grade I and II patients that underwent elective upper limb or lower limb fracture fixation surgeries during the period from August 2005 to October 2007 were studied. Patients were randomly premedicated using 120 mg of etoricoxib or placebo n=100, each. To alleviate postoperative pain, a patient controlled analgesia device was programmed to deliver one mg of morphine intravenously locked lockout time, 6 minutes. Visual analog scale and total postoperative morphine consumption over 24 hours and the adverse effects were recorded. One hundred patients in each group completed the study period. Etoricoxib premedication provides a statistically significant postoperative morphine sparing effect over 24 hours postoperatively. Total morphine consumption was 44.2 (8.2) in the placebo and 35.17 mg in the etoricoxib groups p<0.001. The incidence of nausea and vomiting requiring treatment was lower in the etoricoxib group. p=0.014. The postoperative blood loss was similar in both groups. Etoricoxib is a suitable premedication before traumatic orthopedic surgery as it enhanced postoperative analgesia and reduced the need for morphine. (author)

Systematically review the scientific evidence for efficiency of anti-inflammatory agents against gingivitis, either as solo treatments or adjunctive therapies. A protocol was developed aimed to answer the following focused question: "Are anti-inflammatory agents effective in treating gingivitis as solo or adjunct therapies?" RCTs and cohort studies on anti-inflammatory agents against gingivitis studies were searched electronically. Screening, data extraction and quality assessment were conducted. The primary outcome measures were indices of gingival inflammation. A sub-analysis was performed dividing the active agents into anti-inflammatory and other drugs. The search identified 3188 studies, of which 14 RCTs met the inclusion criteria. The use of anti-inflammatory or other agents, in general showed a higher reduction in the test than in the control in terms of gingival indexes and bleeding scores. Only two RCTs on inflammatory drugs could be meta-analysed, showing a statistically significant reduction in the GI in the experimental group [WMD = -0.090; 95% CI (-0.105; -0.074); p = 0.000]. However, the contribution of both studies to the global result was unbalanced (% weight: 99.88 and 0.12 respectively). Most of the tested material showed beneficial effect as anti-inflammatory agents against gingivitis, either as a single treatment modality or as an adjunctive therapy. © 2014 John Wiley & Sons A/S.

Prosopis chilensis is used locally in Sudan for inflammatory conditions of joints; however, literature lacks scientific evidence for anti-inflammatory effect of this plant. To evaluate anti-inflammatory and analgesic effects of prosopis chilenses. Edema inhibition percent (EI %) and hot plate method were used to evaluate anti-inflammatory and analgesic effects of Prosopis chilenses in Wistar albino rats. Anti-inflammatory and analgesic effects of Prosopis chilenses were compared to indomethacin and acetylsalicylic acid respectively. Ethanolic extract of prosopis chilensis at a dose of 200 and 100mg/kg body weight achieved peak EI% (EI% = 96.1%) and (EI% = 94.4%) three and four hours after oral dosing respectively. The maximum EI% for indomethacin was 97.0% and was recorded after 4 hours following oral administration of the drug at a dose of 5 mg/kg body weight. Prosopis chilensis extracts at doses of 100 and 200 mg/kg body weight significantly increased the rats' response time to hot plate compared to acetylsalicylic acid at a dose rate of 100mg/kg body weight (Pprosopis chilenses. Relevance of these effects to prosopis chilenses phy-to-constituents was discussed.

1997-01-01

Earlier studies have revealed a relationship between the development of myringosclerosis and oxygen-derived free radicals. The latter can be blocked by the anti-inflammatory drug fenspiride. The present study was undertaken to test the ability of fenspiride to prevent myringosclerosis from developing during healing of the tympanic membrane. Myringotomized rats were treated with either topical applications or intraperitoneal injections of fenspiride for 12 days, after which the tympanic membranes were examined by otomicroscopy and studied histologically by light microscopy. Topically applied fenspiride was found to inhibit the development of sclerotic lesions, whereas intraperitoneal injections were ineffective.

Full Text Available ABESTRACT: Introduction & objective: Inflammation is a body defensive response to the endogenous and exogenous stimulators such as chemical, radiation, trauma and invasive microorganism, which result pain and tissue necrosis. There are many natural and synthetic drugs for treatment of inflammation and lot of them are under investigation. Sodium valporate is an antiepileptic drug used particularly in the treatment of primary generalized seizure notably absence, myocolonic seizure, acute manic phase of bipolar disorder and prophylaxis of migraine. The previous observations showed sodium valporate increases level of gamma amino butyric acid (GABA in the central and peripheral nervous system. In acute inflammation, GABA showed a significant attenuation of paw edema and nociception. The aim of this study was evaluation of anti-inflammatory effect of sodium valporate. Materials & Methods: In order to evaluated the anti-inflammatory and antiexudative of sodium valporate doses of 200,400 and 600 mg/kg were investigated on rat paw edema that induced by carrageenan. In addition, the plasma leakage in the inflamed tissue was evaluated by application of trypan blue as intravenous injection. Dexamethason was used as positive control. Results: Results showed sodium valporate doses of 400 and 600 mg/kg decreased inflammatory and exudative effect as compared to control group. Conclusion: Although the anti-inflammatory mechanisms of this drug were not evident but we can say sodium valporate in addition to already proved effects has anti-inflammatory effect.

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.

Full Text Available Many diseases have been described to be associated with inflammatory processes. The currently available anti-inflammatory drug therapy is often not successful or causes intolerable side effects. Thus, new anti-inflammatory substances are still urgently needed. Plants were the first source of remedies in the history of mankind. Since their chemical characterization in the 19th century, herbal bioactive compounds have fueled drug development. Also, nowadays, new plant-derived agents continuously enrich our drug arsenal (e.g., vincristine, galantamine, and artemisinin. The number of new, pharmacologically active herbal ingredients, in particular that of anti-inflammatory compounds, rises continuously. The major obstacle in this field is the translation of preclinical knowledge into evidence-based clinical progress. Human trials of good quality are often missing or, when available, are frequently not suitable to really prove a therapeutical value. This minireview will summarize the current situation of 6 very prominent plant-derived anti-inflammatory compounds: curcumin, colchicine, resveratrol, capsaicin, epigallocatechin-3-gallate (EGCG, and quercetin. We will highlight their clinical potential and/or pinpoint an overestimation. Moreover, we will sum up the planned trials in order to provide insights into the inflammatory disorders that are hypothesized to be beneficially influenced by the compound.

Curcumin, the active ingredient of the spice turmeric, has a long history as an herbal remedy for a variety of diseases. Transdermal drug delivery has been recognized as an alternative route to oral delivery. Proniosomes offer a versatile vesicle delivery concept with the potential for drug delivery via the transdermal route. In this study, different proniosomal gel bases were prepared by the ether injection method, using Span 60 and Span 80, Tween 20, cholesterol, and formulation PA2. They were characterized by scanning electron microscopy, revealing vesicular structures, and assessed for stability and effect on in vitro skin permeation using rat skin. Anti-inflammatory and anti-arthritic effects of formulation PA2 and PB1 were compared with a standard market product containing indomethacin. The effect of formulation PA2 and PB1 was evaluated for acute inflammation in carrageenan induced rat paw edema and for chronic inflammation in complete Freud's adjuvant (CFA) induced arthritis in rats. Further histopathological and radiographic evaluation was performed. The investigated curcumin loaded proniosomal formula proved to be non-irritant, non-toxic, but had lower anti-inflammatory and anti-arthritic effects than the marketed indomethacin products.

Full Text Available Abstract Background Pyrexia, algesia and inflammation are associated with several pathological conditions. Synthetic drugs available for the treatment of these conditions cause multiple unwanted effects. Several studies are ongoing worldwide to find natural healing agents with better safety profile. The current study was thus aimed at evaluating antipyretic, analgesic and anti-inflammatory activities of the methanolic extract of whole plant of V. betonicifolia (VBME. Methods VBME was employed to assess antipyretic activity in yeast induced hyperthermia. Analgesic profile was ascertained in acetic acid induced writhing, hot plat and tail immersion test. Nevertheless, the anti-inflammatory activity was tested in carrageenan induced paw edema and histamine induced inflammatory tests. BALB/c mice were used at test doses of 100, 200 and 300mg/kg body weight intra peritoneally (i.p. Results In yeast induced pyrexia, VBME demonstrated dose dependently (78.23% protection at 300mg/kg, similar to standard drug, paracetamol (90% at 150mg/kg i.p. VBME showed a dose dependent analgesia in various pain models i.e. acetic acid, hot plat and tail immersion having 78.90%, 69.96% and 68.58% protection respectively at 300mg/kg. However, the analgesic action of VBME was completely antagonized by the injection of naloxone like opiate antagonists. Similarly carrageenan and histamine induces inflammation was significantly antagonized by VBME, 66.30% and 60.80% respectively at 300mg/kg. Conclusions It is concluded that VBME has marked antipyretic, analgesic and anti-inflammatory activities in various animal models and this strongly supports the ethnopharmacological uses of Viola betonicifolia as antipyretic, analgesic and anti-inflammatory plant.

Salts of common anti-inflammatory drugs mefenamic acid (MFA), tolfenamic acid (TFA) and naproxen (NPX) with various pyridine derivatives (4-amino pyridine (4AP), 4-dimethylaminopyridine (DMAP) and 2-amino pyridine (2AP)) were synthesized by crystal engineering approach based on the pKa values of API's and the salt former. All the salts were characterized systematically by various spectroscopic methods including FT-IR and 1H NMR and the crystal structure was determined by single-crystal X-ray diffraction techniques (SCXRD). DMAP salt of NPX and 2AP salts of MFA and TFA were not obtained in the salt screening experiments. All the molecular salts exhibited 1:1 molecular stoichiometry in the asymmetric unit and except NPX-2AP salt, all the molecular salts included a water molecule in the crystal lattice. Physicochemical and structural properties between drug-drug molecular salts of MFA-4AP, TFA-4AP and NPX-4AP have been evaluated and it was found that these molecular salts were found to be stable for a time period of six months at ambient condition and further hydration of molecular salts were not observed even at accelerated humid conditions (∼75% RH). It was found that 4AP salts of MFA and TFA and DMAP salts of MFA and TFA are isostructural.

This coadministration is generally regarded as safe, and is included in many of the guidelines on NSAID prescription. However, recent evidence indicates that the GI risks associated with NSAIDs can be potentiated when they are combined with PPIs. This review discusses the GI effects and complications of NSAIDs and how PPIs may potentiate these effects, options for prevention of GI side effects, and appropriate use of PPIs in combination with NSAIDs.

The antioxidant activity of the extracts was measured using scavenging of 2,2′-Diphenyl-1-picrylhydrazyl hydrate (DPPH, bleaching of β-carotene and % inhibition of H2O2. The anti-inflammatory activity was evaluated using carrageenan induced paw edema method on Wistar albino rats. The etahnolic extracts of aerial parts of C. siamea and C. javanica were evaluated for in vivo anti-inflammatory activity against the animal model of female Wistar albino rats. Ethanol extracts showed significant and dose-dependent anti-inflammatory effects. The contents of flavonoids and total phenolic compounds could be correlated with the antioxidant and anti-inflammatory activities observed for C. siamea and C. javanica. Our findings suggest that aerial parts of C. siamea and C. javanica contain potential antioxidant and anti-inflammatory compounds, which could be tested as drug candidates against oxidative and inflammation-related pathological processes in medicinal chemistry studies.

Liposomal drug delivery systems, a promising lipid-based nanoparticle technology, have been known to play significant roles in improving the safety and efficacy of an encapsulated drug. Liposomes, prepared using an optimized proliposome method, were used in the present work to encapsulate piroxicam, a widely prescribed nonsteroidal anti-inflammatory drug. The cytotoxic effects as well as the in vitro efficacy in regulation of inflammatory responses by free-form piroxicam and liposome-encapsulated piroxicam were evaluated using a lipopolysaccharide-sensitive macrophage cell line, RAW 264.7. Cells treated with liposome-encapsulated piroxicam demonstrated higher cell viabilities than those treated with free-form piroxicam. In addition, the liposomal piroxicam formulation resulted in statistically stronger inhibition of pro-inflammatory mediators (ie, nitric oxide, tumor necrosis factor-α, interleukin-1β, and prostaglandin E2) than piroxicam at an equivalent dose. The liposome-encapsulated piroxicam also caused statistically significant production of interleukin-10, an anti-inflammatory cytokine. This study affirms the potential of a liposomal piroxicam formulation in reducing cytotoxicity and enhancing anti-inflammatory responses in vitro.

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.

Non-Steroidal Anti-inflammatory Drugs As Host-Directed Therapy for Tuberculosis: A Systematic Review

2017-06-01

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.

The clinical epidemiological studies included in this thesis fall into three parts. The first part includes studies on birth outcome in women with ulcerative colitis. The second part includes pharmacoepidemiological studies on birth outcome after anti-inflammatory drug therapy in pregnancy, including patients with ulcerative colitis and Crohn's disease. The third part (and the latest publications) includes birth outcome in women with Crohn's disease; and the methods of cohort establishment in these studies are developed and improved due to the knowledge gathered from conducting the earlier studies. The birth outcomes in women with ulcerative colitis are examined in a nationwide, Danish, cohort of women based on data from the Danish National Hospital Discharge Registry and the Danish Medical Birth Registry, and within a Hungarian case-control data set. Our data suggest: 1) Significantly increased risk of preterm birth when women give birth 0-6 months after establishment of the diagnosis. It is considered whether the increased risk may be influenced by disease activity around the time of establishing the diagnosis. 2) No increased risk of giving birth to children with low birth weight, intrauterine growth retardation or congenital abnormalities (evaluated overall). 3) Significantly increased risk of some selected congenital abnormalities (limb deficiencies, obstructive urinary and multiple congenital abnormalities). No other studies have examined the risk of selected congenital abnormalities in children born by women with ulcerative colitis. The pharmacoepidemiological studies on birth outcomes after use of anti-inflammatory drug therapy in pregnancy, including women with ulcerative colitis and Crohn's disease, are based on data from the Hungarian case-control data set, a countywide Danish prescription Database, the Danish National Hospital Discharge Registry, the Danish Medical Birth Registry, and review of selected medical records.

Objective. Infection, inflammation, and neuronal loss are common issues that seriously affect the functionality and longevity of chronically implanted neural prostheses. Minocycline hydrochloride (MH) is a broad-spectrum antibiotic and effective anti-inflammatory drug that also exhibits potent neuroprotective activities. In this study, we investigated the development of biocompatible thin film coatings capable of sustained release of MH for improving the long term performance of implanted neural electrodes. Approach. We developed a novel magnesium binding-mediated drug delivery mechanism for controlled and sustained release of MH from an ultrathin hydrophilic layer-by-layer (LbL) coating and characterized the parameters that control MH loading and release. The anti-biofilm, anti-inflammatory and neuroprotective potencies of the LbL coating and released MH were also examined. Main results. Sustained release of physiologically relevant amount of MH for 46 days was achieved from the Mg2+-based LbL coating at a thickness of 1.25 μm. In addition, MH release from the LbL coating is pH-sensitive. The coating and released MH demonstrated strong anti-biofilm, anti-inflammatory, and neuroprotective potencies. Significance. This study reports, for the first time, the development of a bioactive coating that can target infection, inflammation, and neuroprotection simultaneously, which may facilitate the translation of neural interfaces to clinical applications.

To report 2 cases of corneal perforation associated with the use of oral nonsteroidal anti-inflammatory drugs (NSAIDs). In a 62-year-old woman and a 79-year-old woman, corneal perforation occurred after 7 days and 5 months of oral NSAIDs administration, respectively. After NSAIDs were discontinued, the cornea epithelialized and the anterior chamber formed within 14 and 10 days, respectively. It is well known that topical NSAIDs cause corneal perforation. Observations in the present cases suggest that the oral administration of NSAIDs may also cause corneal damage, and hence, medical professionals should consider the risk of damage to the cornea when administering these drugs orally.

Pain associated with poultry lameness is poorly understood. The anti-nociceptive properties of two non-steroidal anti-inflammatory drugs (NSAIDs) were evaluated using threshold testing in combination with an acute inflammatory arthropathy model. Broilers were tested in six groups (n = 8 per group). Each group underwent a treatment (saline, meloxicam (3 or 5 mg/kg) or carprofen (15 or 25 mg/kg)) and a procedure (Induced (arthropathy-induction) or sham (sham-handling)) prior to testing. Induced groups had Freund’s complete adjuvant injected intra-articularly into the left intertarsal joint (hock). A ramped thermal stimulus (1 °C/s) was applied to the skin of the left metatarsal. Data were analysed using random-intercept multi-level models. Saline-induced birds had a significantly higher skin temperature (± SD) than saline-sham birds (37.6 ± 0.8 °C vs. 36.5 ± 0.5 °C; Z = −3.47, P carprofen: Z = 2.58, P = 0.010) in induced birds. Saline-induced birds also had significantly lower TT than saline-sham birds (Z = −2.17, P = 0.030). This study found direct evidence of an association between inflammatory arthropathies and thermal hyperalgesia, and showed that NSAID treatment maintained baseline thermal sensitivity (via anti-nociception). Quantification of nociceptive responsiveness in a predictable broiler pain model identified thermal anti-hyperalgesic properties of two NSAIDs, which suggested that therapeutically effective treatment was provided at the doses administered. Such validation of analgesic strategies will increase the understanding of pain associated with specific natural broiler lameness types. PMID:24129110

Background 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). Methods and Findings 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

Full Text Available Nicolau syndrome is a rare complication of intramuscular injection that leads to local ischemic necrosis of the skin and adipose tissue. In this paper, we discuss etiologies, risk factors, and treatment options for gluteal Nicolau syndrome referring to patients treated in our hospital. Our study includes 17 women who visited our clinic with symptoms of gluteal necrosis secondary to intramuscular injection. The following variables were taken into account: injection site, drug administered, frequency of injections, the person who administered the injections, needle size, and needle tip color. Magnetic resonance images obtained in the aftermath of intramuscular injection application were carefully analyzed for presence of necrosis, cyst formation and the thickness of the gluteal fat tissue layer. Drugs that had been received in intramuscular injection were exclusively non-steroidal anti-inflammatory drugs. Mean patient BMI was 41.8 (all patients were considered as obese, and mean gluteal fat thickness was 54 mm. Standard length of needles (3.8 cm had been used in procedures. The wounds were treated with primary closure in 11 patients and with local flap therapy in 6 patients. The observed necrosis was a consequence of misplaced gluteal injection, where drugs were injected into the adipose tissue instead of the muscle due to the extreme thickness of the fat layer, on one hand, and the inappropriate length of standard needles, on the other hand. Intramuscular injection should be avoided in obese patients whenever possible: if it is necessary, proper injection technique should be used.

Propolis: a review of its anti-inflammatory and healing actions

Full Text Available Tissue healing is an adaptive biological response by which the organism repairs damaged tissue. The initial stage of healing is represented by an acute inflammatory reaction, in which inflammatory cells migrate to damaged tissue and phagocyte debris. At a later stage, fibroblasts and endothelial cells proliferate and generate a scar. The occurrence of inflammatory processes and healing imperfections have been a concern for hundreds of years, especially for individuals with healing difficulties, such as diabetics and carriers of peripheral circulation deficiencies. A wide variety of natural products have been used as anti-inflammatory and healing agents, with propolis being a remarkable option. Propolis has been used in popular medicine for a very long time; however, it is not a drug intended for all diseases. Currently, the determination of quality standards of propolis-containing products is a major problem due to their varying pharmacological activities and chemical compositions. The aim of this review is to discuss the use of propolis with emphasis on its anti-inflammatory and healing properties.

AIMS: The aim of this study was to investigate the prevalence of chronic kidney disease (CKD) among comparable patients with rheumatoid arthritis (RA) and seronegative inflammatory arthritis, and to explore any predictive factors for renal impairment. METHODS: Consecutive patients with peripheral joint disease (oligo and polyarthritis) were recruited from our inflammatory arthritis clinics. We divided patients in two groups: RA group and seronegative inflammatory arthritis group. The cohort consisted of 183 patients (RA = 107, seronegative arthritis = 76 [psoriatic arthritis = 69, undifferentiated oligoarthritis = 7]). Estimated glomerular filtration rate (eGFR) was calculated using the established Modification of Diet in Renal Disease equation. Demographic details, disease-specific characteristics, anti-rheumatic drugs and the presence of cardiovascular diseases were recorded. RESULTS: In total, 17.48% (n = 32) of the cohort had CKD. There was no statistically significant variation between the two groups as regards baseline demographics, disease characteristics, use of anti-rheumatic drugs and the presence of individual cardiovascular diseases. We found that eGFR and the presence of CKD were similar among these groups. Among patients with CKD, 72% had undiagnosed CKD. No association of statistical significance was noted between CKD and the use of corticosteroids, disease-modifying antirheumatic drugs and anti-tumor necrosis factor agents. The association of cardiovascular diseases with CKD remained significant after adjusting for confounders (age, gender, duration of arthritis, high C-reactive protein, use of anti-rheumatic drugs). CONCLUSIONS: Patients with inflammatory arthritis are more prone to have CKD. This could have serious implications, as the majority of rheumatology patients use non-steroidal anti-inflammatory drugs and different immunosuppressives, such as methotrexate. No association of kidney dysfunction was noted with inflammatory disease

Primary headaches have high epidemiologic impact but their symptomatic treatment often remains problematic. Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used, but their modality of employment and efficacy/differential efficacy are highly variable. This study investigated current NSAID use for episodic headache at an Italian headache center (January 2000 to February 2013). A retrospective evaluation was performed on 6,443 patient records: migraine (n = 2,330), tension-type headache (TTH; n = 807), and migraine plus TTH (n = 3,306). Among migraine patients, 80% had used NSAIDs in the past year. Preferences were: nimesulide (57%), ketoprofen (25%), and ibuprofen (24%); complete efficacy was significantly higher than incomplete/absent efficacy (P headache was higher than could be hypothesized based on guidelines, with NSAID preferences not entirely coinciding with international recommendations. This outcome suggests the need for greater awareness of all treatment options in headache by both patients and physicians. © 2016 World Institute of Pain.

This work reports the synthesis of a novel, aspirin-loaded, linear poly (anhydride ester) and provides mechanistic insights into the release of aspirin from this polymer for anti-inflammatory activity. As compared to conventional drug delivery systems that rely on diffusion based release, incorporation of bioactives in the polymer backbone is challenging and high loading is difficult to achieve. In the present study, we exploit the pentafunctional sugar alcohol (xylitol) to provide sites for drug (aspirin) attachment at its non-terminal OH groups. The terminal OH groups are polymerized with a diacid anhydride. The hydrolysis of the anhydride and ester bonds under physiological conditions release aspirin from the matrix. The resulting poly(anhydride ester) has high drug loading (53%) and displays controlled release kinetics of aspirin. The polymer releases 8.5 % and 20%, of the loaded drug in one and four weeks, respectively and has a release rate constant of 0.0035h -0.61 . The release rate is suitable for its use as an anti-inflammatory agent without being cytotoxic. The polymer exhibits good cytocompatibility and anti-inflammatory properties and may find applications as injectable or as an implantable bioactive material. The physical insights into the release mechanism can provide development of other drug loaded polymers. Copyright © 2017 Elsevier B.V. All rights reserved.

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 (pcost-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.

Human radiation exposure is increasing due to radiation development in science and technology. The development of radioprotective agents is important for protecting patients from the side effects of radiotherapy and for protecting the public from unwanted irradiation. Radioprotective agents are used to reduce the damage caused by radiation in healthy tissues. There are several classes of radioprotective compounds that are under investigation. Analgesics and anti-inflammatory compounds are being considered for treating or preventing the effects of damage due to radiation exposure, or for increasing the chance of survival after exposure to a high dose of radiation. In this study, we investigated the radioprotective effects of some analgesic and anti-inflammatory compounds by evaluating buildup factors. The gamma ray energy absorption (EABF) and exposure buildup factors (EBF) were calculated to select compounds in a 0.015–15 MeV energy region up to a penetration depth of 40 mfp (mean free path). Variations of EABF and EBF with incident photon energy and penetration depth elements were also investigated. Significant variations in both EABF and EBF values were observed for several compounds at the moderate energy region. At energies below 0.15 MeV, EABF and EBF values increased with decreasing equivalent atomic number (Z eq ) of the samples. In addition, EABF and EBF were the largest for ibuprofen, aspirin, paracetamol, naproxen and ketoprofen at 0.05 and 0.06 MeV, respectively, and the EABF value was 0.1 MeV for aceclofenac. From these results, we concluded that the buildup of photons is less for aceclofenac compared to other materials. - Highlights: • Buildup factors of anti-inflammatory drugs have been calculated by a G-P fitting method. • Z eff of diclofenac was observed higher than other compounds. • It was found that buildup of photons is less for aceclofenac and diclofenac. • It would be appealing to use aceclofenac and diclofenac as radioprotective

Nonsteroidal anti-inflammatory drugs (NSAIDs) are a standard treatment for osteoarthritis (OA), but the use of oral NSAIDs has been linked to an elevated risk for cardiovascular and gastrointestinal adverse events and renal toxicity. Topical NSAIDs are thought to afford efficacy that is comparable to oral formulations while reducing widespread systemic drug exposure, which may provide a benefit in terms of safety and tolerability. As a result, European treatment guidelines have, for many years, recommended the use of topical NSAIDs as a safe and effective treatment option for OA. Following the recent approval of several topical NSAID formulations by the US Food and Drug Administration, US treatment guidelines are increasingly recommending the use of topical NSAIDs as an alternative therapy and, in some cases, as a first-line option for OA. This commentary summarizes OA treatment guidelines that are currently available and discusses their potential evolution with regard to the increased inclusion of topical NSAIDs.

Statins are the group of lipid-lowering drugs commonly used to control cardiovascular and cerebrovascular diseases. Statins have potential anti-inflammatory effect by blocking the intermediate metabolites of the mevalonate pathway. The objective of this study was to evaluate the anti-inflammatory effect of statin medication in chronic periodontitis patients. Thirty patients of age group between 40 and 60 years were selected from the outpatient pool of Department of Periodontics, Thaimoogambigai Dental College and Hospital, Chennai. Thirty patients selected were grouped into two groups, Group-I consists of patients with generalized chronic periodontitis and on statin medication and Group-II consists of patients with generalized chronic periodontitis. Clinical parameters were recorded and gingival crevicular fluid (GCF) samples were analyzed for interleukin (IL)-1β using commercially available enzyme-linked immunosorbent assay. The mean GCF IL-1β levels in generalized chronic periodontitis patients who are on statin medication (Group-I) were lower than the generalized chronic periodontitis patients without statin medication (Group-II). Reduction of GCF IL-1β levels in statin users indicate that statins have anti-inflammatory effect on periodontal disease.

Gastric and renal effects of COX-2 selective and non-selective NSAIDs in rats receiving low-dose aspirin therapy

Marcella Goetz MORO

Full Text Available Abstract The consumption of low-dose aspirin (LDA to prevent cardiovascular disease continues to increase worldwide. Consequently, the number of chronic LDA users seeking dental procedures that require complementary acute anti-inflammatory medication has also grown. Considering the lack of literature evaluating this interaction, we analyzed the gastric and renal effects caused by a selective COX-2 inhibitor (etoricoxib and a non-selective COX-2 inhibitor (ibuprofen nonsteroidal anti-inflammatory drug (NSAID in rats receiving chronic LDA therapy. Male Wistar rats were divided into six experimental groups (carboxymethylcellulose (CMC - vehicle; LDA; LDA + ibuprofen; ibuprofen; LDA + etoricoxib; and etoricoxib and submitted to long-term LDA therapy with a subsequent NSAID administration for three days by gavage. After the experimental period, we analyzed gastric and renal tissues and quantified serum creatinine levels. The concomitant use of LDA with either NSAID induced the highest levels of gastric damage when compared to the CMC group (F = 20.26, p 0.05. These results suggest that even the acute use of an NSAID (regardless of COX-2 selectivity can induce gastric damage when combined with the long-term use of low-dose aspirin in an animal model. Additional studies, including clinical assessments, are thus needed to clarify this interaction, and clinicians should be careful of prescribing NSAIDs to patients using LDA.

The use of honey for therapeutic purposes is on the increase and many studies have shown that honey has the ability to influence biological systems including pain transmission. Therefore, this study was designed to investigate the analgesic and anti-inflammatory effects of honey and the effects of concurrent administration of autonomic nervous system blocking drugs. Studies on analgesic activities was carried out using hotplate and formalin-induced paw licking models while the anti-inflammatory activity was by the carrageenan paw oedema method. Animals were distributed into six groups consisting of five animals each. They were administered saline, honey (600 mg/kg), indomethacin (5 mg/kg), autonomic blockers (3 μg/kg of tamsulosin, 20 mg/kg (intraperitoneally) of propranolol, 2 ml/kg of atropine or 10 mg/kg (intra muscularly) of hexamethonium) or honey (200 and 600 mg/kg) with one of the blockers. The results showed that honey reduced pain perception especially inflammatory pain and the administration of tamsulosin and propranolol spared the effect of honey. Hexamethonium also spared the effects of honey at the early and late phases of the test while atropine only inhibited the early phase of the test. However, atropine and hexamethonium spared the anti-inflammatory effects of honey but tamsulosin abolished the effects while propranolol only abolished the anti-inflammatory effects at the peak of the inflammation. The results suggest the involvement of autonomic receptors in the anti-nociceptive and anti-inflammatory effects of honey although the level of involvement depends on the different types of the receptors.

Full Text Available Many biological properties have been attributed to various types of propolis, including anti-inflammatory, antimicrobial, antioxidant, antitumor, wound healing, and immunomodulatory activities. This article reviewed studies published that investigated the anti-inflammatory activity of propolis of different origins and/or its isolated components, focusing on the mechanisms of action underlying this activity and also addressing some aspects of immunomodulatory effects. The search was performed of the following databases: PubMed, Science Direct, HighWire Press, Scielo, Google Academics, Research Gate and ISI Web of Knowledgement. The anti-inflammatory activity was associated with propolis or compounds such as polyphenols (flavonoids, phenolic acids and their esters, terpenoids, steroids and amino acids. CAPE is the most studied compounds. The main mechanisms underlying the anti-inflammatory activity of propolis included the inhibition of cyclooxygenase and consequent inhibition of prostaglandin biosynthesis, free radical scavenging, inhibition of nitric oxide synthesis, reduction in the concentration of inflammatory cytokines and immunosuppressive activity. Propolis was found to exert an anti-inflammatory activity in vivo and in vitro models of acute and chronic inflammation and others studies, indicating its promising potential as anti-inflammatory agent of natural origin and as a source of chemical compounds for the development of new drugs.

Full Text Available Background & objectives: Antidepressants are being used as analgesics for various pain related disorders like neuropathic and non neuropathic pain. Although their analgesic activity is well recognized but anti-inflammatory potential of antidepressants is still inconclusive. Since the antidepressants are used for longer duration, it becomes important to elucidate effect of anti-depressants on blood pressure and gastric mucosa. This study was undertaken to evaluate the anti-inflammatory potential of various antidepressant drugs as well as their effect on blood pressure and gastric tolerability on chronic administration in rats. Methods: Rat paw oedema model was used for studying anti-inflammatory activity, single dose of test drug (venlafaxine 20 and 40 mg/kg, amitryptline 25 mg/kg, fluoxetine 20 mg/kg was administered intraperitoneally 45 min prior to administration of 0.1 ml of 1 per cent carrageenan in sub-planter region. Oedema induced in test group was compared with normal saline treated control group. For studying effect on blood pressure and gastric tolerability, test drugs were administered for 14 days. Blood pressure was recorded on days 0, 7 and 14 using tail cuff method. On day 14, 4 h after drug administration, rats were sacrificed and stomach mucosa was examined for ulcerations. Results: Pretreatment of rats with venlafaxine (40 mg/kg resulted in a significant decrease in paw oedema as compared to control (2.4 ± 0.15 to 1.1 ± 0.16 ml, P<0.01. Similarly, in the group pretreated with fluoxetine, significant decrease in paw oedema was observed in comparison to control (P<0.05. Significant change in mean blood pressure was seen in rats pretreated with venlafaxine 40 mg/kg (126.7 ± 4.2 to 155.2 ± 9.7, P<0.05 and fluoxetine (143.5 ± 2.6 to 158.3 ± 1.2, P<0.05 on day 7. No significant difference with regard to gastric tolerability was observed among groups. Interpretation & conclusions: Our findings showed significant anti-inflammatory

Despite wide availability of physician guidelines for safer use of nonsteroidal anti-inflammatory drugs (NSAIDs) and widespread use of these drugs in the US, NSAID prescribing guidelines have been only modestly effective. To identify and describe comprehensively barriers to provider adherence to NSAID prescribing guidelines. We conducted interviews with 25 physicians, seeking to identify the major influences explaining physician non-adherence to guidelines. Interviews were standardized and structured probes were used for clarification and detail. All interviews were audio-taped and transcribed. Three independent investigators analysed the transcripts, using the constant-comparative method of qualitative analysis. Our analysis identified six dominant physician barriers explaining non-adherence to established NSAID prescribing guidelines. These included (i) lack of familiarity with guidelines, (ii) perceived limited validity of guidelines, (iii) limited applicability of guidelines among specific patients, (iv) clinical inertia, (v) influences of prior anecdotal experiences and (vi) medical heuristics. A heterogeneous set of influences are barriers to physician adherence to NSAID prescribing guidelines. Suggested measures for improving guideline-concordant prescribing should focus on measures to improve physician education and confidence in guidelines, implementation of physician/pharmacist co-management strategies and expansion of guideline scope.

2016-01-01

Plant derived products are not only served as dietary components but also used to treat and prevent the inflammatory associated diseases like cancer. Among the natural products pentacyclic terpenoids including ursolic acid and oleanolic acid are considered as the promising anti-inflammatory therapeutic agents. The current review extensively discusses the anti-inflammatory therapeutic potential of these pentacyclic moieties along with their proposed mechanisms of action. Furthermore, the relevant patents have also been listed to present the health benefits of these promising therapeutic agents to pin down the inflammatory diseases. Expert opinion: Pentacyclic terpenoids are known to negatively down-regulate a variety of extracellular and intracellular molecular targets associated with disease progression. The major anti-inflammatory effects of these molecules have been found to be mediated via inactivation of NFkB, STAT3/6, Akt/mTOR pathways. A number of patents on UA & OA based moieties have been reported between 2010 and 2016. Still there have been only a few compounds which meet the need of sufficient hydro solubility and bioavailability along with higher anti-inflammatory activities. Thus, it is essential to develop novel derivatives of terpenpoids which may not only overcome the solubility issues but also may improve their therapeutic effects. In addition, scientific community may utilize nanotechnology based drug delivery systems so as to increase the bio-availability, selectivity and dosages related problems.

Oxidative damage and inflammation have been pointed out in preclinical studies as the root cause of cancer and other chronic diseases such as diabetes, hypertension, Alzheimer's disease, etc. Epidemiological and clinical studies have suggested that cancer could be prevented or significantly reduced by treatment with anti-oxidant and anti-inflammatory drugs, therefore, curcumin, a principal component of turmeric (a curry spice) showing strong anti-oxidant and anti-inflammatory activities, might be a potential candidate for the prevention and/or treatment of cancer and other chronic diseases. However, curcumin, a highly pleiotropic molecule with an excellent safety profile targeting multiple diseases with strong evidence on the molecular level, could not achieve its optimum therapeutic outcome in past clinical trials, largely due to its low solubility and poor bioavailability. Curcumin can be developed as a therapeutic drug through improvement in formulation properties or delivery systems, enabling its enhanced absorption and cellular uptake. This review mainly focuses on the anti-inflammatory potential of curcumin and recent developments in dosage form and nanoparticulate delivery systems with the possibilities of therapeutic application of curcumin for the prevention and/or treatment of cancer.

However, curcumin, a highly pleiotropic molecule with an excellent safety profile targeting multiple diseases with strong evidence on the molecular level, could not achieve its optimum therapeutic outcome in past clinical trials, largely due to its low solubility and poor bioavailability. Curcumin can be developed as a therapeutic drug through improvement in formulation properties or delivery systems, enabling its enhanced absorption and cellular uptake. This review mainly focuses on the anti-inflammatory potential of curcumin and recent developments in dosage form and nanoparticulate delivery systems with the possibilities of therapeutic application of curcumin for the prevention and/or treatment of cancer.

PURPOSE: Increasing evidence suggests that aspirin use may protect against prostate cancer. In a nationwide case-control study, using Danish high-quality registry data, we evaluated the association between the use of low-dose aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs......) and the risk of prostate cancer. METHODS: We identified 35,600 patients (cases) with histologically verified prostate cancer during 2000-2012. Cases were matched to 177,992 population controls on age and residence by risk-set sampling. Aspirin and nonaspirin NSAID exposure was defined by type, estimated dose......, duration, and consistency of use. We used conditional logistic regression to estimate odds ratios (ORs), with 95 % confidence intervals (CIs), for prostate cancer associated with low-dose aspirin (75-150 mg) or nonaspirin NSAID use, adjusted for potential confounders. RESULTS: Use of low-dose aspirin...

Full Text Available Candida albicans is an opportunistic dimorphic fungus that inhabits various host mucosal sites. It can cause both superficial and serious systemic disease. Conversion from the yeast to the hyphal form has been associated with increased virulence and mucosal invasiveness. The aim of this study was to investigate the effect of sodium diclofenac and aspirin on germs tube formation of different Candida albicans strains. Prostaglandins may play an important role in fungal colonization. Nonsteroidal anti-inflammatory drugs are inhibitors of the cyclooxygenase isoenzymes. These drugs specifically block the biosynthesis of mammalian prostaglandins by inhibiting one or both of cyclooxygenase isoenzymes. In tests for germ tube formation sodium diclofenac reduced the filamentation to the 12.5%- 5.1%. In the presence of aspirin the filamentation was reduced up to 85-45% depending on the tested strain. Our results suggest that cyclooxygenase-depending synthesis of fungal prostaglandins is important for morphogenesis and fungal virulence. Inhibitors of cyclooxygenase isoensymes (aspirin and diclofenac are effective in decreasing germ tube formation of Candida albicans.

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.

15 patients with lymphocytic infiltration of the skin (LIS) were treated with the nonsteroid anti-inflammatory (NSAI) drug proquazone [1-isopropyl-4-phenyl-7-methyl-2(IH)]. In contrast to other NSAI drugs proquazone is a nonacidic compound which is known to be a potent prostaglandin synthesis inhibitor. Of the 15 patients 8 were healed completely with proquazone; in half of these patients lesions recurred but healed with reintroduction of the drug. Two patients remained symptom-free with a small maintenance dose. Two patients showed a partial remission. The treatment was discontinued in 3 patients, in 2 of them because of side effects and in 1 because of lack of response. Two other NSAI drugs, both known to be potent prostaglandin synthesis inhibitors, namely indomethacin and ibuprofen, were tried, however without effect. The present study indicates that proquazone should be considered in the treatment of LIS.

To know the trends of supply, consumption and pattern of use of non-steroidal anti-inflammatory drugs (NSAIDs) in Spain from 1990 through 2003, as well as their costs. Drug utilization study. National Health System, outpatient setting. Information on drug utilization was obtained from the ALHAQUEM database of the Spanish Ministry of Health, which contains the number of packages sold in community pharmacies and charged to the National Health System. Data were expressed in defined daily doses (DDD) per 1000 inhabitants per day (DHD). NSAIDs consumption in Spain increased from 23.67 DHD in 1990 to 45.82 DHD in 2003 (a 93.6% increase). Ibuprofen was the NSAID which showed the greatest increase (15.33 DHD in 2003). The consumption of coxibs reached a maximum of 7.74 DHD in 2001, but decreased to 3.59 DHD in 2003 once prior-authorization programs were set up. Over the study period the share of NSAIDs use with a low gastrointestinal risk increased from 29% to 59%. Overall costs of NSAIDs increased from 117 million euro in 1990 to 329 million euro in 2003. Over the study period the consumption of NSAIDs in Spain has increased twofold while costs increased threefold. The pattern of use has remarkably changed showing an increasing use of NSAIDs with a better gastrointestinal profile. The impact of coxibs marketing has been moderate.

Diclofenac, 2-[2-[(2,6-dichlorophenyl)amino]phenyl]acetic acid, is an important non-steroidal anti-inflammatory drug widely used for human and animals to reduce inflammation and pain. Diclofenac could potentially reach agricultural lands through the application of municipal biosolids or wastewater, and in the absence of any environmental fate data, we evaluated its persistence in agricultural soils incubated in the laboratory. 14 C-Diclofenac was rapidly mineralized without a lag when added to soils varying widely in texture (sandy loam, loam, clay loam). Over a range of temperature and moisture conditions extractable 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.

Full Text Available We wanted to investigate the current knowledge on the impact of diet on anti-TNF response in inflammatory bowel diseases (IBD, to identify dietary factors that warrant further investigations in relation to anti-TNF treatment response, and, finally, to discuss potential strategies for such investigations. PubMed was searched using specified search terms. One small prospective study on diet and anti-TNF treatment in 56 patients with CD found similar remission rates after 56 weeks among 32 patients with good compliance that received concomitant enteral nutrition and 24 with poor compliance that had no dietary restrictions (78% versus 67%, p = 0.51. A meta-analysis of 295 patients found higher odds of achieving clinical remission and remaining in clinical remission among patients on combination therapy with specialised enteral nutrition and Infliximab (IFX compared with IFX monotherapy (OR 2.73; 95% CI: 1.73–4.31, p < 0.01, OR 2.93; 95% CI: 1.66–5.17, p < 0.01, respectively. In conclusion, evidence-based knowledge on impact of diet on anti-TNF treatment response for clinical use is scarce. Here we propose a mechanism by which Western style diet high in meat and low in fibre may promote colonic inflammation and potentially impact treatment response to anti-TNF drugs. Further studies using hypothesis-driven and data-driven strategies in prospective observational, animal and interventional studies are warranted.

Intrauterine infection and inflammation are responsible for the majority of early (PTBs). Anti-inflammatory agents, delivered intra-amniotically together with antibiotics, may be an effective strategy for preventing PTB. In this study, the effects of four cytokine-suppressive anti-inflammatory drugs (CSAIDs: N-acetyl cysteine (NAC), SB239063, TPCA-1 and NEMO binding domain inhibitor (NBDI)) were assessed on human and ovine gestational membrane inflammation. Full-thickness membranes were collected from healthy, term, human placentas delivered by Caesarean section (n=5). Using a Transwell model, they were stimulated ex vivo with γ-irradiation-killed Escherichia coli applied to the amniotic face. Membranes from near-term, ovine placentas were stimulated in utero with lipopolysaccharide, Ureaplasma parvum or saline control and subjected to explant culture. The effects of treatment with CSAIDs or vehicle (1% DMSO) on accumulation of PGE2 and cytokines (human interleukin 6 (IL6), IL10 and TNFα; ovine IL8 (oIL8)) were assessed in conditioned media at various time points (3-20  h). In human membranes, the IKKβ inhibitor TPCA-1 (7  μM) and p38 MAPK inhibitor SB239063 (20  μM) administered to the amniotic compartment were the most effective in inhibiting accumulation of cytokines and PGE2 in the fetal compartment. NAC (10  mM) inhibited accumulation of PGE2 and IL10 only; NBDI (10  μM) had no significant effect. In addition to the fetal compartment, SB239063 also exerted consistent and significant inhibitory effects in the maternal compartment. TPCA-1 and SB239063 suppressed oIL8 production, while all CSAIDs tested suppressed ovine PGE2 production. These results support the further investigation of intra-amniotically delivered CSAIDs for the prevention of inflammation-mediated PTB.

1 The concept that nitric oxide (NO) release can be beneficial in inflammatory conditions has raised more attention in the recent years, particularly with the development of nitric oxide-releasing anti-inflammatory drugs. There is considerable evidence that NO is capable of enhancing the anti-inflammatory benefits of conventional anti-inflammatory drugs. 2 Since hydrocortisone is the most widely used anti-inflammatory drug for the treatment of skin inflammation, we compared the anti-inflammatory effects of hydrocortisone to an NO-releasing derivative of hydrocortisone, NCX 1022, in a murine model of irritant contact dermatitis, induced by epidermal application of benzalkonium chloride. 3 Topical pre- and post-treatment with NCX 1022 (3 nmol) in C57BL6 mice not only reduced ear oedema formation in a dose-dependent manner, but also was significantly more effective than the parent compound during the initial stages of inflammation (from 1 to 5 h). NCX 1022, but not hydrocortisone, significantly inhibited granulocyte recruitment (tissue myeloperoxidase activity). Histological samples of mouse ears treated with NCX 1022 showed significant reduction in both the number of infiltrated cells and disruption of the tissue architecture compared to hydrocortisone-treated tissues. 4 With intravital microscopy, we observed that both pre- and post-treatments with NCX 1022 were more effective than hydrocortisone in terms of inhibiting benzalkonium chloride-induced leukocyte adhesion to the endothelium, without affecting the flux of rolling leukocytes or venule diameter. 5 These results suggest that by releasing NO, NCX 1022 modulates one of the early events of skin inflammation: the recruitment of leukocytes to the site of inflammation. Overall, we have shown that NO-hydrocortisone provided faster and greater protective effects, reducing major inflammatory parameters (leukocyte adhesion and recruitment, oedema formation, tissue disruption) compared to its parental compound.

Full Text Available Marine microalgae are considered a potentially new and valuable source of biologically active molecules for applications in the food industry as well as in the pharmaceutical, nutraceutical and cosmetic sectors. They can be easily cultured, have short generation times and enable an environmentally-friendly approach to drug discovery by overcoming problems associated with the over-utilization of marine resources and the use of destructive collection practices. In this study, 21 diatoms, 7 dinoflagellates and 4 flagellate species were grown in three different culturing conditions and the corresponding extracts were tested for possible antioxidant, anti-inflammatory, anticancer, anti-diabetes, antibacterial and anti-biofilm activities. In addition, for two diatoms we also tested two different clones to disclose diversity in clone bioactivity. Six diatom species displayed specific anti-inflammatory, anticancer (blocking human melanoma cell proliferation and anti-biofilm (against the bacteria Staphylococcus epidermidis activities whereas, none of the other microalgae were bioactive against the conditions tested for. Furthermore, none of the 6 diatom species tested were toxic on normal human cells. Culturing conditions (i.e. nutrient starvation conditions greatly influenced bioactivity of the majority of the clones/species tested. This study denotes the potential of diatoms as sources of promising bioactives for the treatment of human pathologies.

Hydro-alcoholic fruit extract of Cordia myxa was considerably effective on curing acute inflammation in mouse model. Previous studies suggested significant anti-inflammatory activities as well as potential anticancer agent of α-amyrins in seeds. Inhibition of Cyclooxygenase-2 (COX-2) and 5-Lipooxygenase (5-LOX) is significant in cancer prevention and therapeutics although this inhibition with chemo-drugs has its own side-effects. It is shown that these enzymes pathways are related to several cancers including colon, breast and lung cancer. This study was conducted based on Cordia species' α-amyrins as a safer natural anti-cancer compound for inhibition of COX-2 and 5-LOX enzymes by molecular docking. The X-ray crystal structure of COX2 / 5-LOX enzymes and α-amyrins was retrieved and energetically minimized respectively. The binding site and surface of enzymes were detected. Docking studies were performed by AutoDock 4.2 using Lamarckian genetic algorithm (LGA). Finally drug likeness, molecular pharmacokinetic properties and toxicity of α-amyrins was calculated. Molecular Docking revealed hydrogen and hydrophobic interactions between α-amyrins with both active sites of COX-2 and 5-LOX enzymes. Interestingly, it covalently bonded to Fe cofactor of 5-LOX enzyme and chelated this molecule. Base on binding energies (∆G) α-amyrin has more inhibitory effects on 5-LOX (-10.45 Kcal/mol) than COX-2 (-8.02 Kcal/mol). Analysis of molecular pharmacokinetic parameters suggested that α-amyrins complied with most sets of Lipinski's rules, and so it could be a suitable ligand for docking studies. Eventually, bioactivity score showed α-amyrins possess considerable biological activities as nuclear receptor, enzyme inhibitor, GPCR and protease inhibitor ligand. These results clearly demonstrate that α-amyrins could act as potential highly selective COX-/5-LOX inhibitor. Also, it is a safe compound in comparison with classical non-steroidal anti-inflammatory drugs (NSAIDs

Anti-inflammatory actions of acupuncture

Full Text Available Acupuncture has a beneficial effect when treating many diseases and painful conditions, and therefore is thought to be useful as a complementary therapy or to replace generally accepted pharmacological intervention. The attributive effect of acupuncture has been investigated in inflammatory diseases, including asthma, rhinitis, inflammatory bowel disease, rheumatoid arthritis, epicondylitis, complex regional pain syndrome type 1 and vasculitis. Large randomised trials demonstrating the immediate and sustained effect of acupuncture are missing. Mechanisms underlying the ascribed immunosuppressive actions of acupuncture are reviewed in this communication. The acupuncture-controlled release of neuropeptides from nerve endings and subsequent vasodilative and anti-inflammatory effects through calcitonine gene-related peptide is hypothesised. The complex interactions with substance P, the analgesic contribution of β-endorphin and the balance between cell-specific pro-inflammatory and anti-inflammatory cytokines tumour necrosis factor-α and interleukin-10 are discussed.

The Role of Nonsteroidal Anti-Inflammatory Drugs (NSAIDs in the Management of the Post-Embolization Symptoms after Uterine Artery Embolization

Full Text Available Uterine artery embolization (UAE is usually a very painful procedure. Although pain after the procedure can occur as a single symptom, it usually is associated with other symptoms such as nausea, vomiting, pelvic pain, general malaise, fever and leukocytosis that characterize the post-embolization syndrome. Management of the post-embolization symptoms and of pain in particular, is paramount if UAE is to be performed as an outpatient procedure. Different protocols have used analgesic and/or anti-inflammatory agents to control these symptoms. Nonsteroidal anti-inflammatory drugs (NSAIDs are frequently used in association with analgesic drugs to control post-embolization symptoms. In our institution the patients start oral medication with NSAIDs the day before the procedure and continue it during and after UAE. We also mix NSAIDs with the embolizing particles. This enables a reduction in the inflammation present in the uterine fibroids and helps controlling the pain. The purpose of this paper is to review the importance of NSAIDs in the management of the post-embolization symptoms. We describe the protocol that we use in our institution that enables us to perform the procedure on an outpatient basis with same day discharge and good control of the post-embolization symptoms with oral NSAIDs and analgesics.

Development of analgesic and anti-inflammatory controlled-released injectable microemulsions utilising lysine clonixinate (LC) as model drug and generally regarded as safe (GRAS) excipients. Different microemulsions were optimised through pseudo-ternary phase diagrams and characterised measuring droplet size, viscosity, ex vivo haemolytic activity and in vitro drug release. The anti-inflammatory and analgesic activity was tested in mice (Hot plate test) and rats (Carrageenan-induced paw edema test) respectively and their activity was compared to an aqueous solution of LC salt. The aqueous solution showed a faster and shorter response whereas the optimised microemulsion increased significantly (p<0.01) the potency and duration of the analgesic and anti-inflammatory activity after deep intramuscular injection. The droplet size and the viscosity were key factors to control the drug release from the systems and enhance the effect of the formulations. The microemulsion consisting of Labrafil®/Lauroglycol®/Polysorbate 80/water with LC (56.25/18.75/15/10, w/w) could be a promising formulation after buccal surgery due to its ability to control the drug release and significantly achieve greater analgesic and anti-inflammatory effect over 24h.

2016-06-01

Full Text Available Macrophages are one kind of innate immune cells, and produce a variety of inflammatory cytokines in response to various stimuli, such as oxidized low density lipoprotein found in the pathogenesis of atherosclerosis. In this study, the effect of phosphatidylserine on anti-inflammatory activity of curcumin-loaded nanostructured lipid carriers was investigated using macrophage cultures. Different amounts of phosphatidylserine were used in the preparation of curcumin nanoparticles, their physicochemical properties and biocompatibilities were then compared. Cellular uptake of the nanoparticles was investigated using a confocal laser scanning microscope and flow cytometry analysis in order to determine the optimal phosphatidylserine concentration. In vitro anti-inflammatory activities were evaluated in macrophages to test whether curcumin and phosphatidylserine have interactive effects on macrophage lipid uptake behavior and anti-inflammatory responses. Here, we showed that macrophage uptake of phosphatidylserine-containing nanostructured lipid carriers increased with increasing amount of phosphatidylserine in the range of 0%–8%, and decreased when the phosphatidylserine molar ratio reached over 12%. curcumin-loaded nanostructured lipid carriers significantly inhibited lipid accumulation and pro-inflammatory factor production in cultured macrophages, and evidently promoted release of anti-inflammatory cytokines, when compared with curcumin or phosphatidylserine alone. These results suggest that the delivery system using PS-based nanoparticles has great potential for efficient delivery of drugs such as curcumin, specifically targeting macrophages and modulation of their anti-inflammatory functions.

Full Text Available Objective(s:Recently anti-inflammatory effects of antidepressants have been demonstrated. Venlafaxine belongs to newer antidepressants with serotonin norepinephrine reuptake inhibition property. The pain alleviating properties of venlafaxine in different pain models such as neurogenic pain, diabetic neuropathy, and fibromyalgia have been demonstrated. Anti-inflammatory effects of venlafaxine and also its underlying mechanisms remain unclear. The present study was designed to evaluate the anti-inflammatory effects of venlafaxine and determine possible underlying mechanisms. Materials and Methods: We examined the anti-inflammatory effects of intraperitoneal (IP and intracerebroventricular (ICV administration of venlafaxine in the rat model of carrageenan-induced paw edema. Results: Our results showed that both IP (50 and 100 mg/kg and ICV (50 and 100 μg/rat injection of venlafaxine inhibited carrageenan-induced paw edema. Also IP and ICV administration of venlafaxine significantly decreased myeloperoxidase (MPO activity and interleukin (IL-1β and tumor necrosis factor (TNF-α production. Finally, we tried to reverse the anti-inflammatory effect of venlafaxine by yohimbine (5 mg/kg, IP, an alpha2-adrenergic antagonist. Our results showed that applied antagonist failed to change the anti-inflammatory effect of venlafaxine. Conclusion: These results demonstrated that venlafaxine has potent anti-inflammatory effect which is related to the peripheral and central effects of this drug. Also we have shown that anti-inflammatory effect of venlafaxine is mediated mostly through the inhibition of IL-1β and TNF-α production and decreases MPO activity in the site of inflammation.

Nonsteroidal anti-inflammatory (NSAI) drugs are the most commonly used group of drugs today. Increase in the use of standard NSAI for treating pain and inflammation was restricted by the fact that these drugs were proven to possibly cause gastrointestinal and renal toxicity. Meloxicam is a NSAI that has anti-inflammatory, analgesic, and antipyretic effects. This study aims to investigate the effects of meloxicam on stomach, kidney, and liver of rats under light microscopy level. Based on the light microscopic observations, mononuclear cell infiltration and pseudolobular formation was established in liver samples of animals in the experimental group. Metaplasia in surface and glandular epithelia and atrophy were observed in stomach samples. Glomerular stasis-related hypertrophy and focal interstitial nephritis were found in kidneys. It was concluded in this study that meloxicam might cause hepatotoxicity, nephrotoxicity, and gastric metaplasia in rats at a used dose and duration. © The Author(s) 2014.

2-hydroxy arachidonic acid: a new non-steroidal anti-inflammatory drug.

Directory of Open Access Journals (Sweden)

Daniel H Lopez

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.

Anti-inflammatory effects of chronic aspirin on brain arachidonic acid metabolites

Pro-inflammatory and anti-inflammatory mediators derived from arachidonic acid (AA) modulate peripheral inflammation and its resolution. Aspirin (ASA) is a unique non-steroidal anti-inflammatory drug, which switches AA metabolism from prostaglandin E2 (PGE2) and thromboxane B2 (TXB2) to lipoxin A4 (LXA4) and 15-epi-LXA4. However it is unknown whether chronic therapeutic doses of ASA are anti-inflammatory in the brain. We hypothesized that ASA would dampen increases in brain concentrations of AA metabolites in a rat model of neuroinflammation, produced by a 6-day intracerebroventricular infusion of bacterial lipopolysaccharide (LPS). In rats infused with LPS (0.5 ng/h) and given ASA-free water to drink, concentrations in high-energy microwaved brain of PGE2, TXB2 and leukotriene B4 (LTB4) were elevated. In rats infused with artificial cerebrospinal fluid, 6 weeks of treatment with a low (10 mg/kg/day) or high (100 mg/kg/day) ASA dose in drinking water decreased brain PGE2, but increased LTB4, LXA4 and 15-epi-LXA4 concentrations. Both doses attenuated the LPS effects on PGE2, and TXB2. The increments in LXA4 and 15-epi-LXA4 caused by high-dose ASA were significantly greater in LPS-infused rats. The ability of ASA to increase anti-inflammatory LXA4 and 15-epi-LXA4 and reduce pro-inflammatory PGE2 and TXB2 suggests considering aspirin further for treating clinical neuroinflammation.

2013-01-01

Background Gracilaria changii (Xia et Abbott) Abbott, Zhang et Xia, a red algae commonly found in the coastal areas of Malaysia is traditionally used for foods and for the treatment of various ailments including inflammation and gastric ailments. The aim of the study was to investigate anti-inflammatory, gastroprotective and anti-ulcerogenic activities of a mass spectrometry standardized methanolic extract of Gracilaria changii. Methods Methanolic extract of Gracilaria changii (MeOHGCM6 extract) was prepared and standardized using mass spectrometry (MS). Anti-inflammatory activities of MeOHGCM6 extract were examined by treating U937 cells during its differentiation with 10 μg/ml MeOHGCM6 extract. Tumour necrosis factors-α (TNF-α) response level and TNF-α and interleukin-6 (IL-6) gene expression were monitored and compared to that treated by 10 nM betamethasone, an anti-inflammatory drug. Gastroprotective and anti-ulcerogenic activities of MeOHGCM6 extract were examined by feeding rats with MeOHGCM6 extract ranging from 2.5 to 500 mg/kg body weight (b.w.) following induction of gastric lesions. Production of mucus and gastric juice, pH of the gastric juice and non-protein sulfhydryls (NP-SH) levels were determined and compared to that fed by 20 mg/kg b.w. omeprazole (OMP), a known anti-ulcer drug. Results MS/MS analysis of the MeOHGCM6 extracts revealed the presence of methyl 10-hydroxyphaeophorbide a and 10-hydroxypheophytin a, known chlorophyll proteins and several unidentified molecules. Treatment with 10 μg/ml MeOHGCM6 extract during differentiation of U937 cells significantly inhibited TNF-α response level and TNF-α and IL-6 gene expression. The inhibitory effect was comparable to that of betamethasone. No cytotoxic effects were recorded for cells treated with the 10 μg/ml MeOHGCM6 extract. Rats fed with MeOHGCM6 extract at 500 mg/kg b.w. showed reduced absolute ethanol-induced gastric lesion sizes by > 99% (p < 0.05). This protective

The screening of bioactive compound libraries can be an effective approach for repositioning FDA-approved drugs or discovering new treatments for human diseases. Here, methylthiouracil (MTU), an antithyroid drug, was examined for its effects on lipopolysaccharide (LPS)-mediated vascular inflammatory responses. The anti-inflammatory activities of MTU were determined by measuring permeability, human neutrophil adhesion and migration, and activation of pro-inflammatory proteins in LPS-activated human umbilical vein endothelial cells and mice. We found that post-treatment with MTU inhibited LPS-induced barrier disruption, expression of cell adhesion molecules (CAMs), and adhesion/transendothelial migration of human neutrophils to human endothelial cells. MTU induced potent inhibition of LPS-induced endothelial cell protein C receptor (EPCR) shedding. It also suppressed LPS-induced hyperpermeability and neutrophil migration in vivo. Furthermore, MTU suppressed the production of tumor necrosis factor-α (TNF-α) and interleukin (IL)-6, and the activation of nuclear factor-κB (NF-κB) and extracellular regulated kinases (ERK) 1/2 by LPS. Moreover, post-treatment with MTU resulted in reduced LPS-induced lethal endotoxemia. These results suggest that MTU exerts anti-inflammatory effects by inhibiting hyperpermeability, expression of CAMs, and adhesion and migration of leukocytes, thereby endorsing its usefulness as a therapy for vascular inflammatory diseases. - Highlights: • MTU reduced LPS-mediated hyperpermeability in vitro and in vivo. • MTU inhibited LPS-mediated leukocyte adhesion and migration. • MTU inhibited LPS-mediated production of IL-6 and TNF-α. • MTU reduced LPS-mediated mortality and lung injury.

Potassium permanganate is a strong oxidant widely used in drinking water treatment, that can react with organic micropollutants. Thus, the oxidation kinetics and transformation route of seven non-steroidal anti-inflammatory drugs (NSAIDs) upon reaction with potassium permanganate was investigated. A liquid chromatography-quadrupole-time-of-flight-mass spectrometry (LC-Q-TOF-MS) system was used to follow the time course of pharmaceuticals concentrations and for the identification of their by-products. Under strong oxidation conditions (2 mg L(-1) KMnO4, 24 h), only two NSAIDs were significantly degraded: indomethacine and diclofenac. The degradation kinetics of these two drugs was investigated at different concentrations of permanganate, chlorides, phosphates and sample pH by means of a full factorial experimental design. Depending on these factors, half-lives were in the range: 2-270 h for indomethacine and 3-558 h for diclofenac, equivalent to apparent second order constants between 0.65 and 9.5 M(-1) s(-1) and 0.27 and 7.4 M(-1) s(-1), respectively. Permanganate concentration was the most significant factor on NSAIDs oxidation kinetics, but the pH also played a significant role in diclofenac reaction, being faster at acidic pH. In the case of indomethacine, the dose of permanganate seemed also to play an autocatalytic effect. The use of an accurate-mass high resolution LC-Q-TOF-MS system permitted the identification of a total of 13 by-products. The transformation path of these drugs consisted mainly of hydroxylations, decarboxylations and oxidation of aromatic double bonds, with ring opening. The software predicted toxicity of these products indicates that they are expected not to be more toxic than the NSAIDs, with the exception of two indomethacine by-products. Reaction in real samples was slower and/or incomplete for both pharmaceuticals, depending on the organic matter content of the sample. However, still all transformation products could be detected for

Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by elevated oxidative stress and inflammatory biomarkers. The severe side effects of drug used during such disease necessitate the search for new and safe approaches. Food is a rich source of antioxidants and anti-inflammatory bioactive constituents including phenolic compounds, polyunsaturated fatty acids, phytosterols, toccopherols, and carotenoids. We have a series of publications dealing with the anti-inflammatory activity of different food extracts (as nutraceuticals) in experimental animals (acute and chronic inflammation model) and in clinical study (RA patients). Fish oil, primrose oil, extracts of black cumin, fenugreek, liquorice, coriander, tomato, carrot, sweet potato, broccoli, green tea, rosemary, hazelnut, walnut, wheat germ, and date in addition to the probiotic Bifidobacterium bifidum were the nutraceuticals studied. During these studies, changes in inflammatory biomarkers (erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), seromucoids, fibrinogen, tumor necrosis factor-α (TNF-α), prostaglandin E2), oxidative stress (malondialdehyde), antioxidant status (total antioxidant capacity, vitamin C, vitamin E, retinol, β-carotene), the level of copper (Cu) and zinc (Zn) and colonic microflora in response to the administration of nutraceuticals have been assessed. Results of these studies showed that the majority of nutraceuticals studied possess beneficial effect toward chronic inflammatory diseases, which might be due to the presence of one or more of the above-mentioned phytochemicals. Anti-inflammatory and antioxidant nutraceuticals may serve as complementary medicine for the management of RA. © The Author(s) 2012.

To achieve pain control after arthroscopic shoulder surgery, nonsteroidal anti-inflammatory drugs (NSAIDs) are a complement to other analgesics. However, experimental studies have raised concerns that these drugs may have a detrimental effect on soft tissue-to-bone healing and, thus, have a negative effect on the outcome. We wanted to investigate if there are any differences in the clinical outcome after the arthroscopic Bankart procedure for patients who received NSAIDs prescription compared with those who did not. 477 patients with a primary arthroscopic Bankart procedure were identified in the Norwegian shoulder instability register and included in the study. 32.5% received prescription of NSAIDs post-operatively. 370 (78%) of the patients answered a follow-up questionnaire containing the Western Ontario Shoulder Instability index (WOSI). Mean follow-up was 21 months. WOSI at follow-up were 75% in the NSAID group and 74% in the control group. 12% of the patients in the NSAID group and 14% in the control group reported recurrence of instability. The reoperation rate was 5% in both groups. There were no statistically significant differences between the groups. Prescription of short-term post-operative NSAID treatment in the post-operative period did not influence on the functional outcome after arthroscopic Bankart procedures. © 2014 The Authors.

N-aryl derivatives of phthalimide and 4-nitro phthalimide have demonstrated cyclooxygenase inhibitory activity. Also they possess an excellent analgesic and anti-inflammatory activity. In this work, a new series of N-arylmethylideneamino derivatives of phthalimide and 4-nitro phthalimide were designed and synthesized. The designed compounds were synthesized by condensation of the appropriate aldehyde and N-aminophthalimide in ethanol at room temperature at PH around 3. Their analgesic and anti-inflammatory activity were evaluated by acetic acid-induced pain test and carrageenan-induced paw edema test in mice and rats, respectively. The details of the synthesis and chemical characterization of the analogs are described. In vivo screening showed compounds 3a, 3b, 3f and 3h were the most potent analgesic compounds. In addition compounds 3a, 3c, 3d, 3e and 3j indicated comparable anti-inflammatory activity to indomethacin as reference drug.

Full Text Available Ballota pseudodictamnus (L. Benth. (Lamiaceae, Salvia fruticosa Mill. (Lamiaceae and Thapsia garganica L. (Apiaceae are three well-known medicinal plants from the Libyan flora, which have long been used for the treatment of inflammations. The aim of the present study was to investigate, for the first time, the anti-inflammatory property of the methanol (MeOH extracts of the aerial parts of these plants. Shade-dried and ground aerial parts of B. pseudodictamnus, S. fruticosa and T. garganica were Soxhlet-extracted with MeOH. The extracts were concentrated by evaporation under reduced pressure at 40°C. The anti-inflammatory activity of the extracts was evaluated using the carrageenan-induced mice paw edema model. The administration of the extracts at a dose of 500 mg/kg body weight produced statistically significant inhibition (p < 0.05 of edema within 3 h of carrageenan administration. The results demonstrated significant anti-inflammatory properties of the test extracts. Among the extracts, the S. fruticosa extract exhibited the most significant inhibition of inflammation after 3 h (62.1%. Thus, S. fruticosa could be a potential source for the discovery and development of newer anti-inflammatory ‘leads’ for drug development. The anti-inflammatory activity of B. pseudodictamnus and S. fruticosa could be assumed to be related to high levels of phenolic compounds, e.g., flavonoids, present in these plants.

Full Text Available Objective: To evaluate the antinociceptive and anti-inflammatory activities and the toxic effects of Rhipicephalus microplus saliva for elucidating the modulation mechanism between arthropod saliva and host. Methods: For saliva collection, engorged ticks were obtained from a controlled bovine infestation and collected by natural fall. The ticks were fixed and injected pilocarpine 0.2% for induction of salivation. Saliva was collected, lyophilized and stored at - 80 °C. Cytotoxic activity was assessed by the hemolysis method (25, 50, 100, 200 and 300 μ g/mL and MTT cell viability assay (2.5, 5, 10, 20 and 40 μ g/mL for 24, 48 and 72 h. Anti-inflammatory activity was evaluated using the method of neutrophil migration to the peritoneal cavity of mice at doses of 10, 15 and 20 mg/kg; antinociceptive activity was assessed using the acetic acid-induced writhing test, and formalin-induced paw-licking in mice at dose of 15 mg/kg. Results: Saliva did not cause erythrocytes hemolysis at any concentration tested, as well as did not decrease cell viability in the MTT assay. Saliva inhibited neutrophil migration by 87% and 73% at doses of 15 and 20 mg/kg, respectively. In the nociceptive tests, saliva presented analgesic activity of 69.96% in the abdominal writhing test, and of 84.41% in the formalin test. Conclusions: The study proves that Rhipicephalus microplus saliva has significant in vivo anti-inflammatory and antinociceptive activities. The data presented herein support the development of further studies to elucidate the active principles of Rhipicephalus microplus saliva and its mechanism of action and, in future, to develop novel anti-inflammatory and analgesic drugs.

Intervertebral disc (IVD) degeneration is one of the most common causes of low back pain (LBP), the leading disorder in terms of years lived with disability. Inflammation can play a role in LPB, while impairs IVD regeneration. In spite of this, different inflammatory targets have been purposed in the context of IVD regeneration. Anti-inflammatory nanoparticles (NPs) of Chitosan and Poly-(γ-glutamic acid) with a non-steroidal anti-inflammatory drug, diclofenac (Df), were previously shown to counteract a pro-inflammatory response of human macrophages. Here, the effect of intradiscal injection of Df-NPs in degenerated IVD was evaluated. For that, Df-NPs were injected in a bovine IVD organ culture in pro-inflammatory/degenerative conditions, upon stimulation with needle-puncture and interleukin (IL)-1β. Df-NPs were internalized by IVD cells, down-regulating IL-6, IL-8, MMP1 and MMP3, and decreasing PGE2 production, compared with IL-1β-stimulated IVD punches. Interestingly, at the same time, Df-NPs promoted an up-regulation of extracellular matrix (ECM) proteins, namely collagen type II and aggrecan. Allover, this study suggests that IVD treatment with Df-NPs not only reduces inflammation, but also delays and/or decreases ECM degradation, opening perspectives to new intradiscal therapies for IVD degeneration, based on the modulation of inflammation. Degeneration of the IVD is an age-related progressive process considered to be the major cause of spine disorders. The pro-inflammatory environment and biomechanics of the degenerated IVD is a challenge for regenerative therapies. The novelty of this work is the intradiscal injection of an anti-inflammatory therapy based on Chitosan (Ch)/Poly-(γ-glutamic acid) (γ-PGA) nanoparticles (NPs) with an anti-inflammatory drug (diclofenac, Df), previously developed by us. This drug delivery system was tested in a pro-inflammatory/degenerative intervertebral disc ex vivo model. The main findings support the success of an anti-inflammatory

Diclofenac, 2-[2-[(2,6-dichlorophenyl)amino]phenyl]acetic acid, is an important non-steroidal anti-inflammatory drug widely used for human and animals to reduce inflammation and pain. Diclofenac could potentially reach agricultural lands through the application of municipal biosolids or wastewater, and in the absence of any environmental fate data, we evaluated its persistence in agricultural soils incubated in the laboratory. {sup 14}C-Diclofenac was rapidly mineralized without a lag when added to soils varying widely in texture (sandy loam, loam, clay loam). 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.

Benzimidazole derivatives: search for GI-friendly anti-inflammatory analgesic agents

Monika Gaba

2015-07-01

Full Text Available Non-steroidal anti-inflammatory drugs (NSAIDs have been successfully used for the alleviation of pain and inflammation in the past and continue to be used daily by millions of patients worldwide. However, gastrointestinal (GI toxicity associated with NSAIDs is an important medical and socioeconomic problem. Local generation of various reactive oxygen species plays a significant role in the formation of gastric ulceration associated with NSAIDs therapy. Co-medication of antioxidants along with NSAIDs has been found to be beneficial in the prevention of GI injury. This paper describes the synthesis and biological evaluation of N-1-(phenylsulfonyl-2-methylamino-substituted-1H-benzimidazole derivatives as anti-inflammatory analgesic agents with lower GI toxicity. Studies in vitro and in vivo demonstrated that the antioxidant activity of the test compounds decreased GI toxicity.

Four simple, accurate, sensitive and economic Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopic (ATR-FTIR) methods have been developed for the quantitative estimation of some non-steroidal anti-inflammatory drugs. The first method involves the determination of Etodolac by direct measurement of the absorbance at 1716 cm- 1. In the second method, the second derivative of the IR spectra of Tolfenamic acid and its reported degradation product (2-chlorobenzoic acid) was used and the amplitudes were measured at 1084.27 cm- 1 and 1056.02 cm- 1 for Tolfenamic acid and 2-chlorobenzoic acid, respectively. The third method used the first derivative of the IR spectra of Bumadizone and its reported degradation product, N,N-diphenylhydrazine and the amplitudes were measured at 2874.98 cm- 1 and 2160.32 cm- 1 for Bumadizone and N,N-diphenylhydrazine, respectively. The fourth method depends on measuring the amplitude of Diacerein at 1059.18 cm- 1 and of rhein, its reported degradation product, at 1079.32 cm- 1 in their first derivative spectra. The four methods were successfully applied on the pharmaceutical formulations by extracting the active constituent in chloroform and the extract was directly measured in liquid phase mode using a specific cell. Moreover, validation of these methods was carried out following International Conference of Harmonisation (ICH) guidelines.

Non-steroidal anti-inflammatory drugs (NSAIDs) are among the widely used drugs and are often used by pregnant women. However, they can have significant teratogenic effects. The aim of the study was to investigate pregnant women's knowledge about NSAIDs use during pregnancy and their perception and consumption pattern. The study was a cross sectional study on women waiting for a consultation in the selected maternity hospitals in Addis Ababa, Ethiopia. The pregnant women were selected randomly and then interviewed by using standardized questionnaires. A total of 224 pregnant women were involved in the study. Out of those, 203 (90.6%) of them have taken NSAIDs since the beginning of their pregnancy. About 201 (89.7%), 198 (88.4%) and 189 (84.4%) of the pregnant women considered that ibuprofen, diclofenac and aspirin are not NSAIDs respectively. Regarding analgesic effect of NSAIDs, 97 (43.3%) of the pregnant women believed that NSAIDs are effective for treating pain. Acetaminophen was considered as the most effective treatment for pain by 84 (37.50%) of the patients. Acetaminophen is the most common analgesic that was taken by most pregnant women. The knowledge of pregnant women about NSAIDs is poor.

Flufenamic acid (FFA) is a nonsteroidal anti-inflammatory drug (NSAID). It has anti-inflammatory and antipyretic properties. In addition, it modulates multiple channel activities. The mechanisms underlying the pharmacological actions of FFA are presently unclear. Given that AMP-activated protein kinase (AMPK) has both anti-inflammatory and channel-regulating functions, we examined whether FFA induces AMPK activation. 1) Exposure of several different types of cells to FFA resulted in an elevation of AMPKα phosphorylation at Thr172. This effect of FFA was reproduced by functionally and structurally similar mefenamic acid, tolfenamic acid, niflumic acid, and meclofenamic acid. 2) FFA-induced activation of AMPK was largely abolished by the treatment of cells with 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid tetrakis(acetoxymethyl ester) (an intracellular Ca(2+) chelator) or depletion of extracellular Ca(2+), whereas it was mimicked by stimulation of cells with the Ca(2+) ionophore 5-(methylamino)-2-({(2R,3R,6S,8S,9R,11R)-3,9,11-trimethyl-8-[(1S)-1-methyl-2-oxo-2-(1H-pyrrol-2-yl)ethyl]-1,7-dioxaspiro[5.5]undec-2-yl}methyl)-1,3-benzoxazole-4-carboxylic acid (A23187) or ionomycin. 3) FFA triggered a rise in intracellular Ca(2+), which was abolished by cyclosporine, a blocker of mitochondrial permeability transition pore. Cyclosporine also abolished FFA-induced activation of AMPK. 4) Inhibition of Ca(2+)/calmodulin-dependent kinase kinase β (CaMKKβ) with 7-oxo-7H-benzimidazo[2,1-a]benz[de]isoquinoline-3-carboxylic acid acetate (STO-609) or down-regulation of CaMKKβ with short interfering RNA largely abrogated FFA-induced activation of AMPK. 5) FFA significantly suppressed nuclear factor-κB activity and inducible nitric-oxide synthase expression triggered by interleukin-1β and tumor necrosis factor α. This suppression was also largely abrogated by STO-609. Taken together, we conclude that FFA induces AMPK activation through the Ca(2+)-CaMKKβ pathway

Phlebitis is the commonest complication of intravenous infusion. It has been suggested that it is initiated by venoconstriction at the infusion site, hence treatment with a vasodilator may reduce its incidence. A prospective controlled study was carried out on the effect of transdermal glyceryl trinitrate (GTN) and topical anti-inflammatory gel (non-steroidal anti-inflammatory drug; NSAID) on the survival of peripheral intravenous infusion in 386 patients. A total of 34.9% (43 out of 123) of the infusions failed in the control group compared with 14.1% (18 out of 127) in the NSAID group (P NSAI gel and GTN but NSAI gel is more effective than GTN.

Systematic review and meta-analysis. To determine the efficacy of nonsteroidal anti-inflammatory drugs (NSAIDs) on pain reduction, overall improvement, and reported adverse effects in people with sciatica. NSAIDs are one of the most frequently prescribed drugs for sciatica. We updated a 2008 Cochrane Review through June 2015. Randomized controlled trials that compared NSAIDs with placebo, with other NSAIDs, or with other medication were included. Outcomes included pain using mean difference (MD, 95% confidence intervals [95% CI]). For global improvement and adverse effects risk ratios (RR, 95% CI) were used. We assessed level of evidence using the Grades of Recommendation, Assessment, Development and Evaluation approach. Ten trials were included (N = 1651). Nine out of 10 trials were assessed at high risk of bias. For pain reduction (visual analog scale, 0 to 100) NSAIDs were no more effective than placebo (MD -4.56, 95% CI -11.11 to 1.99, quality of evidence: very low). For global improvement NSAIDs were more effective than placebo (RR 1.14 [95% CI 1.03 to 1.27], low quality of evidence). One trial reported the effect of NSAIDs on disability with very low-quality evidence that NSAIDs are no more effective than placebo. There was low-quality evidence that the risk for adverse effects is higher for NSAID than placebo (RR 1.40, 95% CI 1.02 to 1.93). Our findings show very low-quality evidence that the efficacy of NSAIDs for pain reduction is comparable with that of placebo, low-quality evidence that NSAIDs is better than placebo for global improvement and low-quality evidence for higher risk of adverse effects using NSAIDs compared with placebo. The findings must be interpreted with caution, due to small study samples, inconsistent results, and a high risk of bias in the included trials. 1.

The present study was carried out to evaluate the antioxidant and anti-inflammatory capacity, and acute toxicity of Moroccan Erica arborea leaves. Antioxidant capacity was assessed by diphenyle-picryl-hydrazyl (DPPH), phosphomolybdate (PPM) and ferric reducing antioxidant power (FRAP) tests and anti-inflammatory capacity was evaluated by hind paw oedema model using carrageenan-induced inflammation in rat. The acute toxicity was evaluated using mice. Acute toxicity of ethanolic extract of E. arborea showed no sign of toxicity at dose of 5 g/kg B.W. Our extracts have important antioxidant properties. The efficient concentration of the ethanolic extract (10.22 μg/ml) required for decreasing initial DPPH concentration by 50% was comparable to that of standard solution butyl-hydroxy-toluene (BHT) (8.87 μg/ml). The administration of ethanolic extract at doses of 200 and 400mg/kg B.W. was able to prevent plantar oedema and exhibited a significant inhibition against carrageenan-induced inflammation when compared to the control group (NaCl 0.9%) but comparable to those of diclofenac (reference drug). Our results show that the leaves of E. arborea may contain some bioactive compounds which are responsible for the antioxidant and anti-inflammatory activities observed here. Our finding may indicate the possibility of using the extracts of this plant to prevent the antioxidant and inflammatory processes. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Therapeutic Applicability of Anti-Inflammatory and Proresolving Polyunsaturated Fatty Acid-Derived Lipid Mediators

2010-01-01

Full Text Available The enzymatic oxygenation of polyunsaturated fatty acids by lipoxygenases and cyclo-oxygenases is a resourceful mode of formation of specific autacoids that regulate the extent and pace of the inflammatory response. Arachidonate-derived eicosanoids, such as lipoxin A4, prostaglandin (PGD2, PGF2α, PGE2, and PGD2-derived cyclopentenones exert specific roles in counter-regulating inflammation and turning on resolution. Recently recognized classes of autacoids derived from long-chain ω-3 polyunsaturated fatty acids, the E- and D-series resolvins, protectin D1, and maresin 1, act as specialized mediators to dampen inflammation actively, afford tissue protection, stimulate host defense, and activate resolution. It is held that counter-regulatory lipid mediators and the specific molecular pathways activated by such endogenous agonists may be suitable for pharmacological use in the treatment of inflammatory disease. The anti-inflammatory drug aspirin is a striking example of a drug that is able to act in such a manner, namely through triggering the formation of 15-epi-lipoxin A4 and aspirin-triggered resolvins. Different aspects of the therapeutic applicability of lipid mediators have been addressed here, and indicate that the development of innovative pharmacotherapy based on anti-inflammatory and proresolution lipid mediators presents novel prospects for the treatment of inflammatory disease.

Full Text Available We report in vitro and in vivo anti-inflammatory activities of a series of copper(II-lawsone complexes of the general composition [Cu(Law2(LNx(H2O(2-x]·yH2O; where HLaw = 2-hydroxy-1,4-naphthoquinone, x = 1 when LN = pyridine (1 and 2-aminopyridine (3 and x = 2 when LN = imidazole (2, 3-aminopyridine (4, 4-aminopyridine (5, 3-hydroxypyridine (6, and 3,5-dimethylpyrazole (7. The compounds were thoroughly characterized by physical techniques, including single crystal X-ray analysis of complex 2. Some of the complexes showed the ability to suppress significantly the activation of nuclear factor κB (NF-κB both by lipopolysaccharide (LPS and TNF-alpha (complexes 3-7 at 100 nM level in the similar manner as the reference drug prednisone (at 1 μM level. On the other hand, all the complexes 1-7 decreased significantly the levels of the secreted TNF-alpha after the LPS activation of THP-1 cells, thus showing the anti-inflammatory potential via both NF-κB moderation and by other mechanisms, such as influence on TNF-alpha transcription and/or translation and/or secretion. In addition, a strong intracellular pro-oxidative effect of all the complexes has been found at 100 nM dose in vitro. The ability to suppress the inflammatory response, caused by the subcutaneous application of λ-carrageenan, has been determined by in vivo testing in hind-paw edema model on rats. The most active complexes 1-3 (applied in a dose corresponding to 40 μmol Cu/kg, diminished the formation of edema simalarly as the reference drug indomethacine (applied in 10 mg/kg dose. The overall effect of the complexes, dominantly 1-3, shows similarity to anti-inflammatory drug benoxaprofen, known to induce intracellular pro-oxidative effects.

Nigella sativa or "Kalonji" is a naturally occurring plant in Pakistan and other countries which possesses a wide range of medicinal properties, the anti-inflammatory property being one of these. Diclofenac sodium is a commonly used anti-inflammatory drug. The purpose of this study was to compare the anti-inflammatory effect of ethanolic extract of Nigella sativa seeds with that of diclofenac sodium in albino rats. This laboratory randomized controlled trial (RCT) was conducted in the Physiology Department, Services Institute of Medical Sciences (SIMS), Lahore. The study was carried out on 90 male albino rats. Five percent formalin in a dose of 50 µl was injected into sub-plantar surface of right hind paw of each rat to produce inflammation. The rats were randomly divided into three groups of thirty each. Group A was given normal saline (control); group B was given Nigella sativa seed extract; and group C received diclofenac sodium, as a reference drug. Increase in paw diameter, and total and differential leukocyte counts were measured as markers of inflammation. Nigella sativa seeds extract caused significant (pdiclofenac sodium; however, the extract was comparatively less potent than diclofenac sodium. The extract had no significant effect (p>0.05) on the total or differential leukocyte counts. Our results suggest that ethanolic extract of Nigella sativa seeds possesses potent anti-inflammatory effect, in albino rats however, this effect is comparatively less but prolonged than that produced by diclofenac sodium.

Anti-Inflammatory Dimethylfumarate: A Potential New Therapy for Asthma?

2013-01-01

Full Text Available Asthma is a chronic inflammatory disease of the airways, which results from the deregulated interaction of inflammatory cells and tissue forming cells. Beside the derangement of the epithelial cell layer, the most prominent tissue pathology of the asthmatic lung is the hypertrophy and hyperplasia of the airway smooth muscle cell (ASMC bundles, which actively contributes to airway inflammation and remodeling. ASMCs of asthma patients secrete proinflammatory chemokines CXCL10, CCL11, and RANTES which attract immune cells into the airways and may thereby initiate inflammation. None of the available asthma drugs cures the disease—only symptoms are controlled. Dimethylfumarate (DMF is used as an anti-inflammatory drug in psoriasis and showed promising results in phase III clinical studies in multiple sclerosis patients. In regard to asthma therapy, DMF has been anecdotally reported to reduce asthma symptoms in patients with psoriasis and asthma. Here we discuss the potential use of DMF as a novel therapy in asthma on the basis of in vitro studies of its inhibitory effect on ASMC proliferation and cytokine secretion in ASMCs.

Full Text Available OBJECTIVE: The aim of this study is to compare the effects of traditional nonsteroidal anti-inflammatory drugs with nonsteroidal anti-inflammatory drugs that are selective cyclooxygenase-2 (COX-2 inhibitors in the process of bone regeneration in a rat model. MATERIALS AND METHODS: Forty-four Wistar strain rats were subjected to osteotomy of the right femur and randomly divided into 3 groups according to the drug to be given (diclofenac, rofecoxib, or placebo. Each group was divided into 2 subgroups according to the time to euthanasia after the surgery. The animals of Subgroup 1 were submitted to euthanasia 2 weeks after surgery, and those of Subgroup 2, underwent euthanasia 4 weeks after surgery. Radiographic examinations and bone callus histomorphometry were analyzed. RESULTS: No intergroup statistical difference was found in the bone callus area or in bone formation area 2 and 4 weeks after surgery. Intra-group analysis concerning the bone neoformation area inside the callus showed a significant difference within the diclofenac group, which presented less tissue. CONCLUSIONS: Fracture consolidation in Wistar rats occurs within less than 2 weeks, and the use of nonsteroidal anti-inflammatory drugs does not significantly influence this process.OBJETIVO: Comparar os efeitos do uso de antiinflamatórios não-esteróides tradicionais (AINES e AINES que são inibidores seletivos da ciclooxigenase-2 (COX-2, no processo de regeneração óssea em ratos.

In recent years measurable concentrations of non-steroidal anti-inflammatory drugs (NSAIDs) have been shown in the aquatic environment as a result of increasing human consumption. Effects of five frequently used non-steroidal anti-inflammatory drugs (diclofenac, diflunisal, ibuprofen, mefenamic acid and piroxicam in 0.1 mg ml(-1) concentration) in batch cultures of cyanobacteria (Synechococcus elongatus, Microcystis aeruginosa, Cylindrospermopsis raciborskii), and eukaryotic algae (Desmodesmus communis, Haematococcus pluvialis, Cryptomonas ovata) were studied. Furthermore, the effects of the same concentrations of NSAIDs were investigated in natural algal assemblages in microcosms. According to the changes of chlorophyll-a content, unicellular cyanobacteria seemed to be more tolerant to NSAIDs than eukaryotic algae in laboratory experiments. Growth of eukaryotic algae was reduced by all drugs, the cryptomonad C. ovata was the most sensitive to NSAIDs, while the flagellated green alga H. pluvialis was more sensitive than the non-motile green alga D. communis. NSAID treatments had weaker impact in the natural assemblages dominated by cyanobacteria than in the ones dominated by eukaryotic algae, confirming the results of laboratory experiments. Diversity and number of functional groups did not change notably in cyanobacteria dominated assemblages, while they decreased significantly in eukaryotic algae dominated ones compared to controls. The results highlight that cyanobacteria (especially unicellular ones) are less sensitive to the studied, mostly hardly degradable NSAIDs, which suggest that their accumulation in water bodies may contribute to the expansion of cyanobacterial mass productions in appropriate environmental circumstances by pushing back eukaryotic algae. Thus, these contaminants require special attention during wastewater treatment and monitoring of surface waters. Copyright © 2016 Elsevier Ltd. All rights reserved.

Inflammatory disorders are common in modern life, and medicinal plants provide an interesting source for new compounds bearing anti-inflammatory properties. In this regard, Brazilian medicinal plants are considered to be a promising supply of such compounds due to their great biodiversity. To undertake a review on Brazilian medicinal plants with corroborated anti-inflammatory activities by selecting data from the literature reporting the efficacy of plants used in folk medicine as anti-inflammatory, including the mechanisms of action of their extracts and isolated compounds. A search in the literature was undertaken by using the following Web tools: Web of Science, SciFinder, Pub-Med and Science Direct. The terms 'anti-inflammatory' and 'Brazilian medicinal plants' were used as keywords in search engine. Tropicos and Reflora websites were used to verify the origin of the plants, and only the native plants of Brazil were included in this review. The publications reporting the use of well-accepted scientific protocols to corroborate the anti-inflammatory activities of Brazilian medicinal plants with anti-inflammatory potential were considered. We selected 70 Brazilian medicinal plants with anti-inflammatory activity. The plants were grouped according to their anti-inflammatory mechanisms of action. The main mechanisms involved inflammatory mediators, such as interleukins (ILs), nuclear factor kappa B (NF-κB), prostaglandin E2 (PGE2), cyclooxygenase (COX) and reactive oxygen species (ROS). The collected data on Brazilian medicinal plants, in the form of crude extract and/or isolated compounds, showed significant anti-inflammatory activities involving different mechanisms of action, indicating Brazilian plants as an important source of anti-inflammatory compounds.

Full Text Available Infection by influenza A viruses (IAV is frequently characterized by robust inflammation that is usually more pronounced in the case of avian influenza. It is becoming clearer that the morbidity and pathogenesis caused by IAV is a consequence of this inflammatory response, with several components of the innate immune system acting as the main players. It has been postulated that using a therapeutic approach to limit the innate immune response in combination with antiviral drugs has the potential to diminish symptoms and tissue damage caused by IAV infection. Indeed, some anti-inflammatory agents have been shown to be effective in animal models at reducing IAV pathology as a proof of principle. The main challenge in developing such therapies is to selectively modulate signaling pathways that contribute to lung injury while maintaining the ability of the host cells to mount an antiviral response to control virus replication. However, the dissection of those pathways is very complex given the numerous components regulated by the same factors (i.e. NF kappa B transcription factors and the large number of players involved in this regulation, some of which may be undescribed or unknown. This article provides a comprehensive review of the current knowledge regarding the innate immune responses associated with tissue damage by IAV infection, the understanding of which is essential for the development of effective immunomodulatory drugs. Furthermore, we summarize the recent advances on the development and evaluation of such drugs as well as the lessons learned from those studies.

Indoor mold due to water damage causes serious human respiratory disorders, and the remediation to homes, schools, and businesses is a major expense. Prevention of mold infestation of building materials would reduce health problems and building remediation costs. Nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit yeasts and a limited number of filamentous fungi. The purpose of this research was to determine the possible inhibitory activity of nonsteroidal anti-inflammatory drugs (NSAIDs) on germination, fungal growth, and reproduction of Chaetomium globosum and other important filamentous fungi that occur in water-damaged buildings. Several NSAIDs were found to inhibit C. globosum germination, growth, and reproduction. The most effective NSAIDs inhibiting C. globosum were ibuprofen, diflunisal, and diclofenac. Fusarium oxysporum, Fusarium solani, Aspergillus niger, and Stachybotrys atra were also tested on the various media with similar results obtained. However, F. oxysporum and A. niger exhibited a higher level of resistance to aspirin and NaSAL when compared to the C. globosum isolates. The inhibition exhibited by NSAIDs was variable depending on growth media and stage of fungal development. These compounds have a great potential of inhibiting fungal growth on building materials such as gypsum board. Formulations of sprays or building materials with NSAID-like chemical treatments may hold promise in reducing mold in homes and buildings.

Buddleja crispa Benth (Buddlejaceae) is a dense shrub; several species of genus Buddleja have been used in the management of various health conditions including pain and inflammation. The present study was aimed to investigate the analgesic, anti-inflammatory and anti-platelet properties of B. crispa. Male rats (220-270 gm,) and mice (25-30 gm) were randomly divided into different groups (n = 6). Various doses of plant extract of B. crispa, its fractions and pure compounds isolated from the plant were administered intraperitoneally (i.p). The analgesic, anti-inflammatory and anti-platelet activities were assessed using acetic acid and formalin-induced nociception in mice, carrageenan-induced rat paw edema and arachidonic acid-induced platelets aggregation tests. The intraperitoneal administration of the methanolic extract (50 and 100 mg/kg), hexane fraction (10 and 25 mg/kg i.p) exhibited significant inhibition (P < 0.01) of the acetic acid-induced writhing in mice and attenuated formalin-induced reaction time of animals in second phase of the test. Pure compounds BdI-2, BdI-H3 and BH-3 isolated from B. crispa produced significant (P < 0.01) analgesic activity in acetic acid-induced and formalin tests. The crude extract of B. crispa (50-200 mg/kg i.p.) and its hexane fraction inhibited carrageenan-induced rat paw edema with maximum inhibition of 65 and 71% respectively (P < 0.01). The analgesic and anti-inflammatory effect of the plant extract and isolated pure compounds were comparable to diclofenac sodium. B. crispa plant extract (0.5-2.5 mg/mL) produced significant anti-platelet effect (P < 0.01) with maximum inhibition of 78% at 2.5 mg/ml. The findings from our present study suggest that B. crispa possesses analgesic, anti-inflammatory and anti-platelet properties. B. crispa could serve a potential novel source of compounds effective in pain and inflammatory conditions.

Netter, P; Bannwarth, B; Monot, C; Royer, R J; Gaucher, A

1983-09-24

The therapeutic effectiveness of non-steroid anti-inflammatory (NSAI) drugs is partly determined by their passage across the synovial membrane. The synovium can be compared to a double barrier the permeability of which to NSAI drugs depends on the degree of inflammation of the joint and on the pharmacokinetic properties of the drugs (lipophilia, pka, protein-binding). A few hours after one single systemic dose, concentrations in the synovial fluid are higher than in serum. During chronic administration, concentrations of NSAI drugs with a short half-life vary less in synovial fluid than in serum. During steady state, free fractions of NSAI drugs with prolonged half-life may be similar in both compartments.

The haemodynamic effects of non-steroidal anti-inflammatory (NSAI) drugs can be attributed either to their common property of inhibiting the formation of prostaglandins (PG) in the cardiovascular system, or to direct actions on the tone and sensitivity of the resistance vessels in various regions. Indomethacin (IND) is the most frequently studied NSAI drug, in animals and in man. Its cardiovascular effects differ somewhat from those of other NSAI, due to the fact that, besides inhibiting PG formation, IND acts as a direct vasoconstrictor. The stimulatory effect of IND in vascular smooth muscle results in an increased systemic vascular resistance which, although partially compensated by a decreased cardiac output, gives rise to a moderate increase in systemic blood pressure. The vasoconstrictor effect of IND is of particular interest in patients with ischemic heart disease, since it lowers their already decreased coronary flow, and may thereby accentuate the risk of myocardial infarction. Administration of IND also leads to a decreased blood flow in the splanchnic region, the kidneys, and the brain. The cerebral blood flow is lowered by 25-35%; in addition, IND almost entirely erases the hyperemic flow response to hypercapnia. Of other NSAI drugs, at least aspirin and naproxen are completely devoid of such actions on the cerebral circulation. A common vascular effect of all NSAI drugs is a diminution of reactive hyperemia, the local hyperemia that develops in a tissue subjected to a short period of arterial occlusion. Part of this hyperemic response is dependent on an intact vascular PG formation and consequently it is inhibited when PG formation is blocked. In contrast, NSAI drugs do not affect the functional increase in the blood flow in working skeletal muscle.

A new class of nitric oxide (NO•)-releasing nonsteroidal anti-inflammatory drugs (NONO-NSAIDs) were developed in recent years and have shown promising potential as NSAID substitutes due to their gentle nature on cardiovascular and gastrointestinal systems. Since nitric oxide plays a role in regulation of cell adhesion, we assessed the potential use of NONO-NSAIDs as anti-metastasis drugs. In this regard, we compared the effects of NONO-aspirin and a novel NONO-naproxen to those exerted by their respective parent NSAIDs on avidities of human melanoma M624 cells. Both NONO-NSAIDs, but not the corresponding parent NSAIDs, reduced M624 adhesion on vascular cellular adhesion molecule-1 (VCAM-1) by 20–30% and fibronectin by 25–44% under fluid flow conditions and static conditions, respectively. Only NONO-naproxen reduced (∼ 56%) the activity of β1 integrin, which binds to α4 integrin to form very late antigen-4 (VLA-4), the ligand of VCAM-1. These results indicate that the diazeniumdiolate (NO•)-donor moiety is critical for reducing the adhesion between VLA-4 and its ligands, while the NSAID moiety can impact the regulation mechanism of melanoma cell adhesion. -- Highlights: ► NONO-naproxen, a novel nitric oxide-releasing NSAID, was synthesized. ► NONO-NSAIDs, but not their parent NSAIDs, reduced melanoma adhesion. ► NONO-naproxen, but not NONO-aspirin and NSAIDs, reduced activity of β1 integrin.

Association of terpinolene and diclofenac presents antinociceptive and anti-inflammatory synergistic effects in a model of chronic inflammation.

Pharmacological treatment of inflammatory pain is usually done by administration of non-steroidal anti-inflammatory drugs (NSAIDs). These drugs present high efficacy, although side effects are common, especially gastrointestinal lesions. One of the pharmacological strategies to minimize such effects is the combination of drugs and natural products with synergistic analgesic effect. The monoterpene terpinolene (TPL) is a chemical constituent of essential oils present in many plant species, which have pharmacological activities, such as analgesic and anti-inflammatory. The association of ineffective doses of TPL and diclofenac (DCF) (3.125 and 1.25 mg/kg po, respectively) presented antinociceptive and anti-inflammatory effects in the acute (0, 1, 2, 3, 4, 5 and 6 h, after treatment) and chronic (10 days) inflammatory hyperalgesia induced by Freund's complete adjuvant (CFA) in the right hind paw of female Wistar rats (170-230 g, n=6-8). The mechanical hyperalgesia was assessed by the Randall Selitto paw pressure test, which determines the paw withdrawal thresholds. The development of edema was quantified by measuring the volume of the hind paw by plethismography. The TPL/DCF association reduced neutrophils, macrophages and lymphocytes in the histological analysis of the paw, following a standard staining protocol with hematoxylin and eosin and the counts were performed with the aid of optical microscopy after chronic oral administration of these drugs. Moreover, the TPL/DCF association did not induce macroscopic gastric lesions. A possible mechanism of action of the analgesic effect is the involvement of 5-HT2A serotonin receptors, because ketanserin completely reversed the antinociceptive effect of the TPL/DCF association. These results suggest that the TPL/DCF association had a synergistic anti-inflammatory and analgesic effect without causing apparent gastric injury, and that the serotonergic system may be involved in the antinociceptive effect of this association.

Full Text Available Pharmacological treatment of inflammatory pain is usually done by administration of non-steroidal anti-inflammatory drugs (NSAIDs. These drugs present high efficacy, although side effects are common, especially gastrointestinal lesions. One of the pharmacological strategies to minimize such effects is the combination of drugs and natural products with synergistic analgesic effect. The monoterpene terpinolene (TPL is a chemical constituent of essential oils present in many plant species, which have pharmacological activities, such as analgesic and anti-inflammatory. The association of ineffective doses of TPL and diclofenac (DCF (3.125 and 1.25 mg/kg po, respectively presented antinociceptive and anti-inflammatory effects in the acute (0, 1, 2, 3, 4, 5 and 6 h, after treatment and chronic (10 days inflammatory hyperalgesia induced by Freund's complete adjuvant (CFA in the right hind paw of female Wistar rats (170-230 g, n=6-8. The mechanical hyperalgesia was assessed by the Randall Selitto paw pressure test, which determines the paw withdrawal thresholds. The development of edema was quantified by measuring the volume of the hind paw by plethismography. The TPL/DCF association reduced neutrophils, macrophages and lymphocytes in the histological analysis of the paw, following a standard staining protocol with hematoxylin and eosin and the counts were performed with the aid of optical microscopy after chronic oral administration of these drugs. Moreover, the TPL/DCF association did not induce macroscopic gastric lesions. A possible mechanism of action of the analgesic effect is the involvement of 5-HT2A serotonin receptors, because ketanserin completely reversed the antinociceptive effect of the TPL/DCF association. These results suggest that the TPL/DCF association had a synergistic anti-inflammatory and analgesic effect without causing apparent gastric injury, and that the serotonergic system may be involved in the antinociceptive effect of this

A complex study of 147 patients who were taking non-steroid anti-inflammatory drugs (NSAIDs) revealed gastric lesions in 120 patients (81.6%). H2 blocker (ranitidine) was used for treating 40 patients with NSAID-induced gastropathy, proton pump inhibitor (omeprazole) was used for 40 patients, and Gastrozepin combined with Misoprostol--for 40 patients. Pain syndrome and dyspepsia were eliminated in most of the patients as a result of the treatment. Using Gastrozepin and Misoprostol produced an active effect on the trophic processes in the gastric mucous coat and caused erosion and ulcer healing. As compared to ranitidine and omeprazole, Gastrozepin used in combination with Cytotec produces a lower effect on the reduction of the acid-producing stomach function, yet it has a considerably greater effect on the normalization of the gastric mucus structure and restoration of metabolism of the gastric mucous coat collagen.

Methyl palmitate (MP) has been shown earlier to inhibit Kupffer cells and rat peritoneal macrophages. To evaluate the potential of MP to inhibit the activation of other macrophages, RAW cells (macrophages of alveolar origin) were treated with varying concentrations of MP (0.25, 0.5, 1 mM). Assessment of cytotoxicity using MTT assay revealed that 0.25 and 0.5 mM are not toxic to RAW cells. MP was able to inhibit the phagocytic function of RAW cells. Treatment of cells with MP 24 hours prior to LPS stimulation significantly decreased nitric oxide release and altered the pattern of cytokines release; there was a significant decrease in TNF-α and a significant increase in IL-10 compared to the controls. However, there is a non-significant change in IL-6 level. Furthermore, phosphorylation of inhibitory kappa B (IκBα) protein was significantly decreased in RAW cells treated with 0.5 mM MP after LPS stimulation. Based upon the in-vitro results, it was examined whether MP treatment will be effective in preventing bleomycin-induced lung inflammation and fibrosis in-vivo. Bleomycin given by itself caused destruction of the lung architecture characterized by pulmonary fibrosis with collapse of air alveoli and emphysematous. Bleomycin induced a significant increase in hydroxyproline level and activated NF-κB, p65 expression in the lung. MP co-treatment significantly ameliorated bleomycin effects. These results suggest that MP has a potential of inhibiting macrophages in general. The present study demonstrated for the first time that MP has anti-inflammatory and antifibrotic effect that could be through NF-kB inhibition. Thus MP like molecule could be a promising anti-inflammatory and antifibrotic drug. - Research highlights: →Methyl palmitate is a universal macrophage inhibitor. →It could be a promising nucleus of anti-inflammatory and antifibrotic drugs. →The underlying mechanism of these effects could be through NF-kB inhibition.

Background: Nigella sativa or Kalonji is a naturally occurring plant in Pakistan and other countries which possesses a wide range of medicinal properties, the anti-inflammatory property being one of these. Diclofenac sodium is a commonly used anti-inflammatory drug. The purpose of this study was to compare the anti-inflammatory effect of ethanolic extract of Nigella sativa seeds with that of diclofenac sodium in albino rats. Method: This laboratory randomized controlled trial (RCT) was conducted in the Physiology Department, Services Institute of Medical Sciences (SIMS), Lahore. The study was carried out on 90 male albino rats. Five percent formalin in a dose of 50 meu was injected into sub-plantar surface of right hind paw of each rat to produce inflammation. The rats were randomly divided into three groups of thirty each. Group A was given normal saline (control); group B was given Nigella sativa seed extract; and group C received diclofenac sodium, as a reference drug. Increase in paw diameter, and total and differential leukocyte counts were measured as markers of inflammation. Results: Nigella sativa seeds extract caused significant (p<0.05) reduction in the paw inflammatory response in albino rats. The effect was longer in duration than the effect caused by diclofenac sodium; however, the extract was comparatively less potent than diclofenac sodium. The extract had no significant effect (p>0.05) on the total or differential leukocyte counts. Conclusion: Our results suggest that ethanolic extract of Nigella sativa seeds possesses potent anti-inflammatory effect, in albino rats however, this effect is comparatively less but prolonged than that produced by diclofenac sodium.

Drug-metabolizing enzymes (DMEs) are primarily down-regulated during infectious and inflammatory diseases, leading to disruption in the metabolism of small molecule drugs (smds), which are increasingly being prescribed therapeutically in combination with biologics for a number of chronic diseases. The biologics may exert pro- or anti-inflammatory effect, which may in turn affect the expression/activity of DMEs. Thus, patients with infectious/inflammatory diseases undergoing biologic/smd treatment can have complex changes in DMEs due to combined effects of the disease and treatment. Areas covered: We will discuss clinical biologics-SMD interaction and regulation of DMEs during infection and inflammatory diseases. Mechanistic studies will be discussed and consequences on biologic-small molecule combination therapy on disease outcome due to changes in drug metabolism will be highlighted. Expert opinion: The involvement of immunomodulatory mediators in biologic-SMDs is well known. Regulatory guidelines recommend appropriate in vitro or in vivo assessments for possible interactions. The role of cytokines in biologic-SMDs has been documented. However, the mechanisms of drug-drug interactions is much more complex, and is probably multi-factorial. Studies aimed at understanding the mechanism by which biologics effect the DMEs during inflammation/infection are clinically important.

Sulindac, a non-steroidal anti-inflammatory drug, has been shown to exert an anti-tumor effect on several types of cancer. To determine the effect of sulindac on intracellular signaling pathways in host immune cells such as macrophages, we investigated the effect of the drug on interferon gamma (IFNγ)-induced expression of signal transducer and activator of transcription 1 (STAT1) and other genes in mouse macrophage-like cell line RAW264.7 cells. Sulindac, but not aspirin or sodium salicylate, inhibited IFNγ-induced expression of the CXC ligand 9 (CXCL9) mRNA, a chemokine for activated T cells, whereas the interferon-induced expression of CXCL10 or IFN regulatory factor-1 was not affected by sulindac. Luciferase reporter assay demonstrated that sulindac inhibited IFNγ-induced promoter activity of the CXCL9 gene. Surprisingly, sulindac had no inhibitory effect on IFNγ-induced STAT1 activation; however, constitutive nuclear factor κB activity was suppressed by the drug. These results indicate that sulindac selectively inhibited IFNγ-inducible gene expression without inhibiting STAT1 activation

Subacute thyroiditis is a transient inflammatory thyroid disease of unknown etiology. The primary goal for treatment is to mitigate inflammation. The aim of this retrospective study was to compare the therapeutic effects of prednisolone and nonsteroidal anti-inflammation drugs in patients with subacute thyroiditis. In this study, 53 consecutive Japanese patients who had been diagnosed with were referred to our hospital for further management. After excluding 11 patients (9 did not need treatment, 2 did not meet the criteria for diagnosis of subacute thyroiditis), the remaining 42 patients were treated either with prednisolone (n = 25) or loxoprofen (n = 17). We compared the time periods required for resolution of clinical symptoms and signs and normalization of thyroid function between the two groups. The mean dose of prednisolone was 15.0 (range, 14-16) mg/day and that of loxoprofen was 180 mg/day. The time period to normalization of thyroid function was comparable between the prednisolone and loxoprofen groups (25, 18-36, vs 32, 21-39 days, p = 0.388). However, the time period for resolution of symptoms was shorter under prednisolone than loxoprofen (7, 7-12 days, vs 21, 14-32 days, p thyroiditis was superior to nonsteroidal anti-inflammation drugs with regard to resolution of symptoms.

Full Text Available Inflammation is the major causative factor of different diseases such as cardiovascular disease, diabetes, obesity, osteoporosis, rheumatoid arthritis, inflammatory bowel disease, and cancer. Anti-inflammatory drugs are often the first step of treatment in many of these diseases. The present study is aimed at evaluating the anti-inflammatory properties of isoorientin, a selective cyclooxygenase-2 (COX-2 inhibitor isolated from the tubers of Pueraria tuberosa, in vitro on mouse macrophage cell line (RAW 264.7 and in vivo on mouse paw edema and air pouch models of inflammation. Isoorientin reduced inflammation in RAW 264.7 cell line in vitro and carrageenan induced inflammatory animal model systems in vivo. Cellular infiltration into pouch tissue was reduced in isoorientin treated mice compared to carrageenan treated mice. Isoorientin treated RAW 264.7 cells and animals showed reduced expression of inflammatory proteins like COX-2, tumor necrosis factor-α (TNF-α, interleukin-6 (IL-6, 5-lipoxygenase (5-LOX, and interleukin 1-β (IL-1-β both in vitro and in vivo. The antioxidant enzyme levels of catalase and GST were markedly increased in isoorientin treated mice compared to carrageenan treated mice. These results suggest that isoorientin, a selective inhibitor of COX-2, not only exerts anti-inflammatory effects in LPS induced RAW cells and carrageenan induced inflammatory model systems but also exhibits potent antioxidant properties.

Inflammations and immune-related diseases including rheumatoid arthritis are widespread in the entire globe. The treatment of these illnesses is mainly based on the use of synthetic and biotechnological drugs, in recent years. Tunisian traditional medicine is a potential source of new remedies namely Citrullus colocynthis Schrad. (Cucurbitaceae): endemic in southern Tunisia and used in folk medicine to treat many inflammation disorders. Our goal was to assess the in vivo analgesic and anti-inflammatory activities of Tunisian Citrullus colocynthis immature fruit and seed organic extracts (petroleum ether, chloroform, ethyl acetate, acetone and finely methanol extract). Yields of prepared organic extracts are gravimetrically determined. For the analgesic and anti-inflammatory activities, we have used respectively, the acetic acid writhing test in mice and the carrageenan-induced paw edema assay in rats. All extracts displayed an important analgesic and anti-inflammatory activities at different doses without inducing any side effects. This study has demonstrated the analgesic and anti-inflammatory activities of Citrullus colocynthis immature fruit and seed extracts. Experiment results provide scientific insight into the ancient practice of utilizing Citrullus colocynthis Schrad. as analgesic and as anti-inflammatory agents.

Non-Steroidal Anti-Inflammatory Drug Use and Genomic DNA Methylation in Blood.

Lauren E Wilson

Full Text Available Non-steroidal anti-inflammatory drug (NSAID use is associated with decreased risk of some cancers. NSAID use modulates the epigenetic profile of normal colonic epithelium and may reduce risk of colon cancer through this pathway; however, the effect of NSAID use on the DNA methylation profile of other tissues including whole blood has not yet been examined.Using the Sister Study cohort, we examined the association between NSAID usage and whole genome methylation patterns in blood DNA. Blood DNA methylation status across 27,589 CpG sites was evaluated for 871 women using the Illumina Infinium HumanMethylation27 Beadchip, and in a non-overlapping replication sample of 187 women at 485,512 CpG sites using the Infinium HumanMethylation450 Beadchip. We identified a number of CpG sites that were differentially methylated in regular, long-term users of NSAIDs in the discovery group, but none of these sites were statistically significant in our replication group.We found no replicable methylation differences in blood related to NSAID usage. If NSAID use does effect blood DNA methylation patterns, differences are likely small.

Full Text Available Objective: To evaluate the wound healing potency of aqueous extract of Aerva monsoniae (A. monsoniae by in vitro method using fertilized eggs, in vivo analgesic and anti inflammatory activity in rodents and the anti bacterial activity on the bacterial strains that infect the wound. Methods: The whole plant of A. monsoniae was extracted with water and then subjected to preliminary chemical screening. It was then evaluated for in ova angiogenesis on fertilized white leg horn eggs using the concentrations of 200-600 毺 g/mL. The analgesic activity was evaluated in mice using the dose 100 and 250 mg/kg. The anti inflammatory activity was evaluated in rats using the dose 250 mg/kg and 500 mg/kg. In both the parameters water was used as the control and diclofenac was used the standard. The anti bacterial activity on Staphylococcus aureus and Pseudomonas aerugenosa was performed. Results: The phytochemical screening revealed the presence of tannins, flavonoids and saponins. The in ova angiogenesis revealed a dose dependent activity which proves the wound healing claim of the plant as more number of blood capillaries were formed at the site of the drug. The plant proved to be a potent analgesic and anti inflammatory agent at doses 1 00 mg/kg and 250 mg/kg. The anti bacterial activity was present but at higher doses. Conclusions: The parameters studied in the present investigation proved that the plant is a potent wound healer. Further in vivo wound healing studies on animal model is desired. As the extract showed potent analgesic, anti inflammatory and anti bacterial properties, it can be considered that when formulated into suitable formulation, and it can reduce the pain, inflammation and infections related to wound very well.

Full Text Available There is increased focus on developed non-steroidal anti-inflammatory drugs (NSAIDs containing a pyridazine nucleus. The NSAIDs are one of the most commonly used medications worldwide to inhibit cyclooxygenase (COX-1 and COX-2 enzyme in varying extent by inhibiting prostaglandin (PGEs synthesis for the treatment of pain, inflammation, arthritis and edema. Their routine and long-term use causes gastrointestinal (GIT and renal toxicities. In order to minimize these side-effects, selective COX-2 inhibitors are prepared with an improved GIT and renal safety profile relative to other NSAIDs. The recent development toward the effective NSAIDs agents causes dual COX and lipooxygenase inhibitory effects because COX-2 inhibitors cause cardiovascular problems. The literature stimulated these above findings. Our attention has been focused on the series of pyridazine or other derivatives that were reported or will be reported in the future as anti-inflammatory, analgesic, anti-arthritic as well as anti-edemic agent.

Salicytamide is a new drug developed through molecular modelling and rational drug design by the molecular association of paracetamol and salicylic acid. This study was conducted to assess the acute oral toxicity, antinociceptive, and antioedematogenic properties of salicytamide. Acute toxicity was based on the OECD 423 guidelines. Antinociceptive properties were investigated using the writhing, hot plate and formalin tests in Swiss mice. Antioedematogenic properties were evaluated using the carrageenan-induced paw oedema model and croton oil-induced dermatitis in Wistar rats. Salicytamide did not promote behavioural changes or animal deaths during acute oral toxicity evaluation. Furthermore, salicytamide exhibited peripheral antinociceptive activity as evidenced by the reduction in writhing behaviour (ED50 = 4.95 mg/kg) and licking time in the formalin test's inflammatory phase. Also, salicytamide elicited central antinociceptive activity on both hot plate test and formalin test's neurogenic phase. Additionally, salicytamide was effective in reducing carrageenan or croton oil-induced oedema formation. Overall, we have shown that salicytamide, proposed here as a new NSAID candidate, did not induce oral acute toxicity and elicited both peripheral antinociceptive effects (about 10-25 times more potent than its precursors in the writhing test) and antioedematogenic properties. Salicytamide also presented central antinociceptive activity, which seems to be mediated through opioid-independent mechanisms. These findings reveal salicytamide as a promising antinociceptive/antioedematogenic drug candidate.

Femtosecond dynamics of a non-steroidal anti-inflammatory drug (piroxicam) in solution: The involvement of twisting motion

Gil, Michał; Douhal, Abderrazzak

2008-06-01

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.

Human phospholipase A₂ ( h PLA₂) of the IIA group (HGIIA) catalyzes the hydrolysis of membrane phospholipids, producing arachidonic acid and originating potent inflammatory mediators. Therefore, molecules that can inhibit this enzyme are a source of potential anti-inflammatory drugs, with different action mechanisms of known anti-inflammatory agents. For the study and development of new anti-inflammatory drugs with this action mechanism, snake venom PLA₂ ( sv PLA₂) can be employed, since the sv PLA₂ has high similarity with the human PLA₂ HGIIA. Despite the high similarity between these secretory PLA₂s , it is still not clear if these toxins can really be employed as an experimental model to predict the interactions that occur with the human PLA₂ HGIIA and its inhibitors. Thus, the present study aims to compare and evaluate, by means of theoretical calculations, docking and molecular dynamics simulations, as well as experimental studies, the interactions of human PLA₂ HGIIA and two sv PLA₂s , Bothrops toxin II and Crotoxin B (BthTX-II and CB, respectively). Our theoretical findings corroborate experimental data and point out that the human PLA₂ HGIIA and sv PLA₂ BthTX-II lead to similar interactions with the studied compounds. From our results, the sv PLA₂ BthTX-II can be used as an experimental model for the development of anti-inflammatory drugs for therapy in humans.

The metabolism of benzo({alpha})pyrene is mediated by the mixed function oxidase system including the cytochrome P450-dependent aryl hydrocarbon hydroxylase. The data of the present study revealed the ability of various commonly used anti-inflammatory drugs to alter the activity of this enzyme system, where all the tested drugs, namely phenyl butazone, ketoprofen, piroxicam, and acetaminophen, caused an increase in both the activity of aryl hydrocarbon hydroxylase and the cytochrome P450 content whether administered as a single dose or as a repeated dose for 6 consecutive days. The percentage of change for all drugs except phenyl butazone was proportional to the duration of drug administration. On the other hand, pyrazole which is chemically related to phenyl butazone, had no significant effect when administered as a single dose but caused a decrease in both studied parameters when administered as a repeated dose for 6 consecutive days. The mechanisms by which these commonly used drugs modify the aryl hydrocarbon hydroxylase activity and the cytochrome p450 content are discussed in the text.

2014-01-01

The recent research area endeavors to discover ultimate multi-target ligands, an increasingly feasible and attractive alternative to existing mono-targeted drugs for treatment of complex, multi-factorial inflammation process which underlays plethora of debilitated health conditions. In order to improvise this option, exploration of relevant chemical core scaffold will be an utmost need. Privileged benzimidazole scaffold being historically versatile structural motif could offer a viable starting point in the search for novel multi-target ligands against multi-factorial inflammation process since, when appropriately substituted, it can selectively modulate diverse receptors, pathways and enzymes associated with the pathogenesis of inflammation. Despite this remarkable capability, the multi-target capacity of the benzimidazole scaffold remains largely unexploited. With this in focus, the present review article attempts to provide synopsis of published research to exemplify the valuable use of benzimidazole nucleus and focus on their suitability as starting scaffold to develop multi-targeted anti-inflammatory ligands.

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.

A pulsatile ultrasound controlled drug release platform with diclofenac-loaded alginate microcapsules (fabricated with a home-made electrostatic device, 75% embedded rate) was established to evaluate anti-inflammation efficiency. Better anti-inflammation efficiency was found using the ultrasound system and the drug delivery can be adjusted based on the programmed ultrasound cycle. The results of the in vitro study show that an approx. 30% higher drug release rate was obtained by using continuous ultrasound irradiation (9-Watt, 180 min), and an approx. 16% higher drug release rate was obtained by using pulsatile ultrasound irradiation (9-Watt, 60 min) compared to without ultrasound activation. For the in vivo study, the anti-inflammatory test with carrageenan-induced rat's paw edema shows that diclofenac-loaded microcapsules followed by ultrasound irradiation (9-Watt, 60 min) contributed to an 81% inhibition rate, which was significantly higher than diclofenac only (approx. 60% higher). In addition, because of their heat conducting properties, gold nanoparticles encapsulated in the diclofenac-loaded microcapsules resulted in better drug release efficiency, but tended to depress the anti-inflammation effect.

2010-06-01

Full Text Available Inflammation is the response of living tissues to injury. The process affects physiological changes such as erythema, edema, asthma and fever. Non-steroid Anti-inflammatory Drugs (NSAIDs have been developed since they could inhibit inflammation process because of its ability to inhibit biosynthesis of prostaglandin, one of inflammation mediators, through inhibition of cyclooxigenase (COX enzymes. Molecules, which have been reported having anti-inflammatory activity, for example, are curcumin, some curcumin derivatives and curcumin analogues. One of curcumin analogues that has been  developed is pentagamavunon-0 (PGV-0 whose IUPAC name is 2,5-bis(4'-hidroxy-3'-methoxy-benzylidenecyclo-pentanone. But PGV-0, which is like curcumin, practically insoluble in water, so it causes problems in the development. The aim of this research is to synthesize a derivative of PGV-0, a natrium salt of PGV-0 (natrium pentagamavunonate-0/Na-pentagamavunonate-0, which is hoped to have a better anti-inflammatory activity and solubility in water than PGV-0. PGV-0 was synthesized by reacting vanillin and cyclopentanone catalized by acid. Na-pentagamavunonate-0 was synthesized with PGV-0 as a starting material using an appropriate method.

Full Text Available Background: In mammals lipoic acid (LA and its reduced form dihydrolipoic acid (DHLA function as cofactors for multienzymatic complexes catalyzing the decarboxylation of α-ketoacids. Moreover, LA is used as a drug in a variety of diseases including inflammatory diseases. The aim of the study was to examine anti-inflammatory properties of LA metabolites.Material/methods:The present paper reports the chemical synthesis of 2,4-bismethylthio-butanoic acid (BMTBA and tetranor-dihydrolipoic acid (tetranor-DHLA. BMTBA is one of the biotransformation products of LA, while tetranor-DHLA is an analogue of DHLA. Structural identity of these compounds was confirmed by 1H NMR. These compounds were assessed for their anti-inflammatory activity in mice. For this purpose, the zymosan-induced peritonitis and the carrageenan-induced hind paw edema animal models were applied.Results/conclusions: The obtained results indicated that the early vascular permeability measured at 30 min of zymosan-induced peritonitis was significantly inhibited in groups receiving BMTBA (10, 30, 50 mg/kg. The early infiltration of neutrophils measured at 4 hours of zymosan-induced peritonitis was inhibited in the group receiving BMTBA (50 mg/kg and tetranor-DHLA (50 mg/kg. The results indicated that the increase in paw edema was significantly inhibited in the groups receiving BMTBA (50, 100 mg/kg and tetranor-DHLA (30, 50 mg/kg. In summary, the present studies clearly demonstrated that both BMTBA and tetranor-DHLA were able to act as anti-inflammatory agents. This is the first study examining in vivo the anti-inflammatory properties of LA metabolites.

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

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 We investigated the anti-inflammatory, antinociceptive and ulcerogenic activity of a zinc-diclofenac complex (5.5 or 11 mg/kg in male Wistar rats (180-300 g, N = 6 and compared it to free diclofenac (5 or 10 mg/kg and to the combination of diclofenac (5 or 10 mg/kg and zinc acetate (1.68 or 3.5 mg/kg. The carrageenin-induced paw edema and the cotton pellet-induced granulomatous tissue formation models were used to assess the anti-inflammatory activity, and the Hargreaves model of thermal hyperalgesia was used to assess the antinociceptive activity. To investigate the effect of orally or intraperitoneally (ip administered drugs on cold-induced gastric lesions, single doses were administered before exposing the animals to a freezer (-18ºC for 45 min in individual cages. We also evaluated the gastric lesions induced by multiple doses of the drugs. Diclofenac plus zinc complex had the same anti-inflammatory and antinociceptive effects as diclofenac alone. Gastric lesions induced by a single dose administered per os and ip were reduced in the group treated with zinc-diclofenac when compared to the groups treated with free diclofenac or diclofenac plus zinc acetate. In the multiple dose treatment, the complex induced a lower number of the most severe lesions when compared to free diclofenac and diclofenac plus zinc acetate. In conclusion, the present study demonstrates that the zinc-diclofenac complex may represent an important therapeutic alternative for the treatment of rheumatic and inflammatory conditions, as its use may be associated with a reduced incidence of gastric lesions.

BACKGROUND: Regular aspirin use is associated with reduced risk of several malignancies. Epidemiologic studies analyzing aspirin, nonaspirin nonsteroidal anti-inflammatory drug (NSAID), and acetaminophen use and ovarian cancer risk have been inconclusive. METHODS: We analyzed pooled data from 12...... population-based case-control studies of ovarian cancer, including 7776 case patients and 11843 control subjects accrued between 1992 and 2007. Odds ratios (ORs) for associations of medication use with invasive epithelial ovarian cancer were estimated in individual studies using logistic regression...... and combined using random effects meta-analysis. Associations between frequency, dose, and duration of analgesic use and risk of ovarian cancer were also assessed. All statistical tests were two-sided. RESULTS: Aspirin use was associated with a reduced risk of ovarian cancer (OR = 0.91; 95% confidence interval...

1999-04-01

In addition to effects in the periphery through inhibition of prostaglandin synthesis, several lines of evidence suggest that nonsteroidal anti-inflammatory drugs (NSAIDs) act in the central nervous system. The possibility that the central action of NSAIDs involves regulation of opioid receptors was investigated by quantitative autoradiography of mu, delta, and kappa sites in rat brain slices. Increased (p lysine clonixinate. Labeling of delta receptors was lower in the lateral septum, and kappa sites decreased in thalamic nuclei. These effects were not mediated through direct interaction with opioid-binding sites, since receptor-binding assays using rat brain membranes confirmed that clonixinate up to 1 x 10(-4) mol/l does not inhibit mu, delta, and kappa receptor specific binding. Central effects of NSAIDs might, therefore, involve interaction with the opioid receptor system through indirect mechanisms.

Full Text Available Necrotizing sialometaplasia is a rare, benign, self-limiting, necrotizing process involving the minor salivary glands, mainly the mucoserous glands of the hard palate. It is thought to be the result of an ischemic event of the vasculature supplying the salivary gland lobules. Some predisposing factors such as smoking, use of alcohol, denture wearing, recent surgery, traumatic injuries, respiratory infections, systemic diseases bulimia, and anorexia have been described. Herein we present a case of necrotizing sialometaplasia of the hard palate in a patient without known predisposing factors, in our opinion, resulting from the use of topical anti-inflammatory drug. After diagnosis, the patient underwent treatment with chlorhexidine gluconate and a full palatal acrylic guard to protect the exposed bone from food residues during meals. After the sixth week the lesion regressed.

Full Text Available Macrophages and dendritic cells (DC share the same precursor and play key roles in immunity. Modulation of their behaviour to achieve an optimal host response towards an implanted device is still a challenge. Here we compare the differentiation process and polarisation of these related cell populations and show that they exhibit different responses to chitosan (Ch, with human monocyte-derived macrophages polarising towards an anti-inflammatory phenotype while their DC counterparts display pro-inflammatory features. Macrophages and DC, whose interactions with biomaterials are frequently analysed using fully differentiated cells, were cultured directly on Ch films, rather than exposed to the polymer after complete differentiation. Ch was the sole stimulating factor and activated both macrophages and DC, without leading to significant T cell proliferation. After 10 d on Ch, macrophages significantly down-regulated expression of pro-inflammatory markers, CD86 and MHCII. Production of pro-inflammatory cytokines, particularly TNF-α, decreased with time for cells cultured on Ch, while anti-inflammatory IL-10 and TGF-β1, significantly increased. Altogether, these results suggest an M2c polarisation. Also, macrophage matrix metalloproteinase activity was augmented and cell motility was stimulated by Ch. Conversely, DC significantly enhanced CD86 expression, reduced IL-10 secretion and increased TNF-α and IL-1β levels. Our findings indicate that cells with a common precursor may display different responses, when challenged by the same biomaterial. Moreover, they help to further comprehend macrophage/DC interactions with Ch and the balance between pro- and anti-inflammatory signals associated with implant biomaterials. We propose that an overall pro-inflammatory reaction may hide the expression of anti-inflammatory cytokines, likely relevant for tissue repair/regeneration.

In addition to their well-known anti-inflammatory actions, some of the nonsteroidal anti-inflammatory drugs (NSAIDs) appear to have an analgesic effect. In human subjects, the changes in threshold and intensity of sensations evoked by mechanical, chemical, and thermal stimulation of the cornea induced by topical administration of two commercial NSAIDs, diclofenac sodium (Voltaren; Novartis, Basel, Switzerland) and flurbiprofen (Ocuflur; Allergan, Irvine, CA), were studied. Corneal sensitivity was measured in 10 young, healthy subjects with a gas esthesiometer. Chemical (10%-70% CO2 in air), mechanical (0-264 mL/min), and thermal (corneal temperature changes between -4.5 degrees C and +3 degrees C around the normal value) stimuli were applied to the center of the cornea. The intensity and perceived magnitude of the psychophysical attributes of the evoked sensation were scored at the end of the pulse in a 10-cm, continuous visual analog scale (VAS). The threshold was expressed as the stimulus intensity that evoked a VAS score >0.5. Sensitivity was measured in both eyes of each subject on two separate days, one without treatment and the other 30 minutes after topical application of 0.03% flurbiprofen (seven subjects) or 0.1% diclofenac sodium (six subjects). Diclofenac attenuated significantly all the sensation parameters evoked by high-intensity mechanical, chemical, and thermal stimuli. Flurbiprofen produced a slight reduction of the sensations evoked by mechanical and chemical stimulation that became significant only for the irritation caused by chemical stimuli of maximum intensity (70% CO2). None of the drugs modified significantly the detection threshold of the different stimuli. Flurbiprofen had a very limited effect on sensations evoked by corneal stimulation, whereas diclofenac reduced the intensity of sensations evoked by stimuli of different modality, suggesting a mild local anesthetic effect of this drug on all types of corneal sensory fibers.

Treatments with nonsteroidal anti-inflammatory drugs (NSAIDs) have increased the number of patients with gastrointestinal complications. Qing Dai has been traditionally used in Chinese herbal medicine for various inflammatory diseases such as ulcerative colitis. We previously reported that Qing Dai suppressed inflammations by scavenging reactive oxygen species (ROS) in ulcerative colitis patients. Thus, Qing Dai can attenuate the production of ROS, which play an important role in NSAID-induced gastrointestinal injuries. In this study, we aimed to elucidate whether Qing Dai decreased mitochondrial ROS production in NSAID-treated gastrointestinal cells by examining cellular injury, mitochondrial membrane potentials, and ROS production with specific fluorescent indicators. We also performed electron paramagnetic resonance measurement in isolated mitochondria with a spin-trapping reagent (CYPMPO or DMPO). Treatments with indomethacin and aspirin induced cellular injury and mitochondrial impairment in the gastrointestinal cells. Under these conditions, mitochondrial alterations were observed on electron microscopy. Qing Dai prevented these complications by suppressing ROS production in gastrointestinal cells. These results indicate that Qing Dai attenuated the ROS production from the NSAID-induced mitochondrial alteration in the gastrointestinal epithelial cells. Qing Dai treatment may be considered effective for the prevention NSAID-induced gastrointestinal injury.

To investigate the benefit of preoperative treatment with either topical nonsteroidal anti-inflammatory drug (NSAID) or steroid in terms of clinical outcomes following trabeculectomy. Prospective, randomized placebo-controlled trial. Sixty-one patients. Between July 2005 and October 2007, 61 consecutive medically uncontrolled glaucoma patients scheduled for first-time trabeculectomy were randomized to 1 of 3 study topical medication groups: nonsteroidal anti-inflammatory drugs (ketorolac), steroids (fluorometholone), or placebo (artificial tears). Patients instilled 1 drop 4 times daily for 1 month before the procedure and were examined on days 1 and 2, at weeks 1, 2, and 4, and at months 3, 6, 12, 18, and 24 after trabeculectomy. Incidence of postoperative surgical or medical interventions (needling, laser suture lysis, needling revision, and intraocular pressure [IOP]-lowering medication). Fifty-four patients (54 eyes) were entered for analysis. The mean number of preoperative medications was 2.3+/-0.9. The mean baseline IOP was 21.0+/-6.0 mmHg. The mean postoperative target IOP was 16.5+/-1.8 mmHg. The mean follow-up was 23.6+/-4.0 months. The percentage of patients requiring needling within the first year was 41% in the placebo group, 6% in the NSAID, and 5% in the steroid group (P = 0.006). The percentage of patients requiring IOP-lowering medication to reach the target IOP at 1 year was 24% in the placebo group, 18% in the NSAID group, and 0% in the steroid group (P = 0.054 overall; P = 0.038 for steroids vs. others). The log-rank test showed a significant (P = 0.019) difference in medication-free survival curves between the different groups. More specifically, patients in the steroid group needed significantly less medication over the total follow-up (P = 0.007). Topical ketorolac or fluorometholone for 1 month before surgery was associated with improved trabeculectomy outcomes in terms of likelihood of postoperative needling. In the steroid group, there was

McCabe, Erin; Narayanan, Srihari

2009-10-01

The goal of this literature review is to discuss recent discoveries in the pathophysiology of dry eye and the subsequent evolution of diagnostic and management techniques. The mechanisms of various anti-inflammatory treatments are reviewed, and the efficacy of common pharmacologic agents is assessed. Anti-inflammatory therapy is evaluated in terms of its primary indications, target population, and utility within a clinical setting. The Medline PubMed database and the World Wide Web were searched for current information regarding dry eye prevalence, pathogenesis, diagnosis, and management. After an analysis of the literature, major concepts were integrated to generate an updated portrayal of the status of dry eye syndrome. Inflammation appears to play a key role in perpetuating and sustaining dry eye. Discoveries of inflammatory markers found within the corneal and conjunctival epithelium of dry eye patients have triggered recent advancements in therapy. Pharmacologic anti-inflammatory therapy for dry eye includes 2 major categories: corticosteroids and immunomodulatory agents. Fatty acid and androgen supplementation and oral antibiotics have also shown promise in dry eye therapy because of their anti-inflammatory effects. Anti-inflammatory pharmacologic agents have shown great success in patients with moderate to severe dry eye when compared with alternative treatment modalities. A deeper understanding of the link between inflammation and dry eye validates the utilization of anti-inflammatory therapy in everyday optometric practice.

Cordia dichotoma G. Forst. is an important medicinal plant of family Boraginaceae. Traditionally, its leaves are used to treat fever, headache, and joint pain but its medicinal activities have not been proven by research. To evaluate the analgesic, anti-inflammatory, and antipyretic activity of C. dichotoma G. Forst. leaf extract. The various extracts of leaf powder were prepared by using soxhlet apparatus. The methanol extract was selected for pharmacological study. To evaluate analgesic activity, Eddy's hot plate method, to study anti-inflammatory activity, carageenan-induced rat paw edema method, and to study antipyretic activity, yeast-induced pyrexia method was used. SD female rats (180-200 g) were used for the study. In all three tests, the methanol extract high dose (400 mg/kg) was found to be highly significant as compared to standard drug. This study proved the traditional uses of plant leaves and concluded the analgesic, anti-inflammatory, and antipyretic activity of the leaf methanol extract.

2014-01-01

Background Root bark of mulberry (Morus alba L.) has been used in herbal medicine as anti-phlogistic, liver protective, kidney protective, hypotensive, diuretic, anti-cough and analgesic agent. However, the anti-cancer activity and the potential anti-cancer mechanisms of mulberry root bark have not been elucidated. We performed in vitro study to investigate whether mulberry root bark extract (MRBE) shows anti-inflammatory and anti-cancer activity. Methods In anti-inflammatory activity, NO was measured using the griess method. iNOS and proteins regulating NF-κB and ERK1/2 signaling were analyzed by Western blot. In anti-cancer activity, cell growth was measured by MTT assay. Cleaved PARP, ATF3 and cyclin D1 were analyzed by Western blot. Results In anti-inflammatory effect, MRBE blocked NO production via suppressing iNOS over-expression in LPS-stimulated RAW264.7 cells. In addition, MRBE inhibited NF-κB activation through p65 nuclear translocation via blocking IκB-α degradation and ERK1/2 activation via its hyper-phosphorylation. In anti-cancer activity, MRBE deos-dependently induced cell growth arrest and apoptosis in human colorectal cancer cells, SW480. MRBE treatment to SW480 cells activated ATF3 expression and down-regulated cyclin D1 level. We also observed that MRBE-induced ATF3 expression was dependent on ROS and GSK3β. Moreover, MRBE-induced cyclin D1 down-regulation was mediated from cyclin D1 proteasomal degradation, which was dependent on ROS. Conclusions These findings suggest that mulberry root bark exerts anti-inflammatory and anti-cancer activity. PMID:24962785

Grewia asiatica Linn. (Family: Tiliaceae), called Phalsa in Hindi is an Indian medicinal plant used for a variety of therapeutic and nutritional uses. The root bark of the plant is traditionally used in rheumatism (painful chronic inflammatory condition). The present study demonstrates the analgesic and anti-inflammatory activity of root bark of G. asiatica in rodents. The methanolic extract of Grewia asiatica (MEGA) and aqueous extract of Grewia asiatica (AEGA) of the bark were prepared and subjected to phytochemical tests and pharmacological screening for analgesic and anti-inflammatory effect in rodents. Analgesic effect was studied using acetic acid-induced writhing in mice and hot plate analgesia in rats while anti-inflammatory activity was investigated using carrageenan-induced paw oedema in rats. The MEGA or AEGA was administered orally in doses of 200 and 400 mg/kg/day of body weight. Data were analysed by one-way analysis of variance followed by Dunnett's test. The extracts showed a significant inhibition of writhing response and increase in hot plate reaction time and also caused a decrease in paw oedema. The effects were comparable with the standard drugs used. The present study indicates that root bark of G. asiatica exhibits peripheral and central analgesic effect and anti-inflammatory activity, which may be attributed to the various phytochemicals present in root bark of G. asiatica.

Full Text Available Andrographolide (AG is an abundant component of plants of the genus Andrographis and has a number of beneficial properties including neuroprotective, anticancer, anti-inflammatory, and antidiabetic effects. Despite numerous pharmacological studies, the precise mechanism of AG is still ambiguous. Thus, in the present study, we investigated the molecular mechanisms of AG and its target proteins as they pertain to anti-inflammatory responses. AG suppressed the production of nitric oxide (NO and prostaglandin E2 (PGE2, as well as the mRNA abundance of inducible NO synthase (iNOS, tumor necrosis factor-alpha (TNF-α, cyclooxygenase (COX-2, and interferon-beta (IFN-β in a dose-dependent manner in both lipopolysaccharide- (LPS- activated RAW264.7 cells and peritoneal macrophages. AG also substantially ameliorated the symptoms of LPS-induced hepatitis and EtOH/HCl-induced gastritis in mice. Based on the results of luciferase reporter gene assays, kinase assays, and measurement of nuclear levels of transcription factors, the anti-inflammatory effects of AG were found to be clearly mediated by inhibition of both (1 extracellular signal-regulated kinase (ERK/activator protein (AP-1 and (2 IκB kinase ε (IKKε/interferon regulatory factor (IRF-3 pathways. In conclusion, we detected a novel molecular signaling pathway by which AG can suppress inflammatory responses. Thus, AG is a promising anti-inflammatory drug with two pharmacological targets.

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.

Purpose The purpose of this paper is to reduce inappropriate non-steroidal anti-inflammatory prescribing in primary care patients with chronic kidney disease (CKD). Once diagnosed, CKD management involves delaying progression to end stage renal failure and preventing complications. It is well established that non-steroidal anti-inflammatories have a negative effect on kidney function and consequently, all nephrology consensus groups suggest avoiding this drug class in CKD. Design/methodology/approach The sampling criteria included all practice patients with a known CKD risk factor. This group was refined to include those with an estimated glomerular filtration rate (eGFR)<60 ml/min per 1.73m2 (stage 3 CKD or greater). Phase one analysed how many prescriptions had occurred in this group over the preceding three months. The intervention involved creating an automated alert on at risk patient records if non-steroidal anti-inflammatories were prescribed and discussing the rationale with practice staff. The re-audit phase occurred three months' post intervention. Findings The study revealed 728/7,500 (9.7 per cent) patients at risk from CKD and 158 (2.1 per cent) who were subsequently found to have an eGFR<60 ml/min, indicating=stage 3 CKD. In phase one, 10.2 per cent of at risk patients had received a non-steroidal anti-inflammatory prescription in the preceding three months. Additionally, 6.2 per cent had received non-steroidal anti-inflammatories on repeat prescription. Phase two post intervention revealed a significant 75 per cent reduction in the total non-steroidal anti-inflammatories prescribed and a 90 per cent reduction in repeat non-steroidal anti-inflammatory prescriptions in those with CKD. Originality/value The study significantly reduced non-steroidal anti-inflammatory prescription in those with CKD in primary care settings. It also created a CKD register within the practice and an enduring medication alert system for individuals that risk nephrotoxic

Plants from genus Lavandula have been used as anti-inflammatory drugs in Mediterranean traditional medicine. Nowadays, there is a growing interest for complementary medicine, including herbal remedies, to treat inflammatory bowel disease (IBD). To test the anti-inflammatory properties of Lavandula dentata and Lavandula stoechas extracts in two inflammatory experimental models: TNBS model of rat colitis and the carrageenan-induced paw edema in mice, in order to mimic the intestinal conditions and the extra-intestinal manifestations of human IBD, respectively. The extracts were characterized through the qualitative HPLC analysis. Then, they were assayed in vitro and in vivo. In vitro studies were performed in BMDMs and CMT-93 epithelial cells with different concentrations of the extracts (ranging from 0.1 to 100µg/ml). The extracts were tested in vivo in the TNBS model of rat colitis (10 and 25mg/kg) and in the carrageenan-induced paw edema in mice (10, 25 and 100mg/kg). L. dentata and L. stoechas extracts displayed immunomodulatory properties in vitro down-regulating different mediators of inflammation like cytokines and nitric oxide. They also showed anti-inflammatory effects in the TNBS model of colitis as evidenced by reduced myeloperoxidase activity and increased total glutathione content, indicating a decrease of neutrophil infiltration and an improvement of the oxidative state. Besides, both extracts modulated the expression of pro-inflammatory cytokines and chemokines, and ameliorated the altered epithelial barrier function. They also displayed anti-inflammatory effects in the carrageenan-induced paw edema in mice, since a significant reduction of the paw thickness was observed. This was associated with a down-regulation of the expression of different inducible enzymes like MMP-9, iNOS and COX-2 and pro-inflammatory cytokines, all involved in the maintenance of the inflammatory condition. L. dentata and L. stoechas extracts showed intestinal anti-inflammatory

Full Text Available We describe a case of epileptic seizures occurring after the use of a COX-2 inhibitor. A 61-year-old man was admitted to our department because of a generalized tonic-clonic seizure. EEG showed generalized slowdown of the activity. Neuroimaging and blood samples studies did not evidence alterations, but a careful pharmacological history revealed that the patient had taken the COX-2 inhibitor etoricoxib to treat lumbago few days before the onset of clinical symptoms. No seizures were reported after etoricoxib discontinuation and an EEG resulted to be normal two months after this. Conclusion. Knowing the pharmacological history of a patient is important for understanding the clinical presentation and selecting appropriate treatment. This is, to the best of our knowledge, the first reported case of generalized seizures associated with the use of COX-2 inhibitors.

Sida (Malvaceae) has been used as a traditional remedy for the treatment of diarrhoea, malarial, gastrointestinal dysentery, fevers, asthma and inflammation. This study evaluates the anti-inflammatory, cytotoxic and anti-cholinergic activities of Sida rhombifolia Linn. whole plant for the first time. S. rhombifolia whole plant was extracted by n-hexane, ethyl acetate and methanol using Soxhlet apparatus. The plant extracts were evaluated for their antioxidant (DPPH, FIC and FRAP), anti-inflammatory (NO and protein denaturation inhibitions), cytotoxic (MTT) and anti-cholinesterase (AChE) properties in a range of concentrations to obtain IC 50 values. GC-MS analysis was carried out on the n-hexane extract. The ethyl acetate extract exhibited the most significant antioxidant activities by scavenging DPPH radicals and ferrous ions with EC 50 of 380.5 and 263.4 μg/mL, respectively. In contrast, the n-hexane extract showed the strongest anti-inflammatory activity with IC 50 of 52.16 and 146.03 μg/mL for NO and protein denaturation inhibition assays, respectively. The same extract also revealed the strongest effects in anti-cholinesterase and cytotoxic tests at the concentration of 100 μg/mL, AChE enzyme inhibition was 58.55% and human cancer cells, SNU-1 and Hep G2 inhibition was 68.52% and 47.82%, respectively. The phytochemicals present in the n-hexane extract are palmitic acid, linoleic acid and γ-sitosterol. The present study revealed that the n-hexane extract possessed relatively high pharmacological activities in anti-inflammation, cytotoxicity and anti-cholinesterase assays. Thus, further work on the detail mechanism of the bioactive phytochemicals which contribute to the biological properties are strongly recommended.

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

Full Text Available Traditional nonsteroidal anti-inflammatory drugs (NSAIDs are known to cause gastritis, gastric and duodenal ulcers, and gastrointestinal (GI blood loss, as well as alterations in small bowel permeability. Patients at a high risk for these complications include those who are older than 60 years of age, those with a previous history of complicated peptic disease and bleeding, and those who take high dose or multiple NSAIDs, including low dose aspirin, corticosteroids or anticoagulants. The introduction of selective inhibitors of cyclo-oxygenase-2 (COX-2 has provided effective treatment of inflammatory arthritis and musculoskeletal pain, with dramatic reductions in the risk of GI adverse events. The two most widely prescribed coxibs are celecoxib and rofecoxib, and others are being developed. Endoscopic studies have revealed that coxibs are only half as likely to induce upper GI ulceration than are traditional NSAIDs, and are as safe as placebo. Furthermore, the newer drugs do not cause excessive blood loss from the GI tract and do not affect small bowel permeability. The Vioxx Gastrointestinal Outcomes Research Study (VIGOR revealed that the incidence of myocardial infarction was significantly lower with naproxen than rofecoxib, although this study was not designed to look at this endpoint. Coxibs are an important addition to the pharmacotherapy of inflammatory disease.

Full Text Available Objectives. To evaluate the cost-effectiveness of etoricoxib (90 mg relative to celecoxib (200/400 mg, and the nonselective NSAIDs naproxen (1000 mg and diclofenac (150 mg in the initial treatment of ankylosing spondylitis in Norway. Methods. A previously developed Markov state-transition model was used to estimate costs and benefits associated with initiating treatment with the different competing NSAIDs. Efficacy, gastrointestinal and cardiovascular safety, and resource use data were obtained from the literature. Data from different studies were synthesized and translated into direct costs and quality adjusted life years by means of a Bayesian comprehensive decision modeling approach. Results. Over a 30-year time horizon, etoricoxib is associated with about 0.4 more quality adjusted life years than the other interventions. At 1 year, naproxen is the most cost-saving strategy. However, etoricoxib is cost and quality adjusted life year saving relative to celecoxib, as well as diclofenac and naproxen after 5 years of follow-up. For a willingness-to-pay ceiling ratio of 200,000 Norwegian krones per quality adjusted life year, there is a >95% probability that etoricoxib is the most-cost-effective treatment when a time horizon of 5 or more years is considered. Conclusions. Etoricoxib is the most cost-effective NSAID for initiating treatment of ankylosing spondylitis in Norway.

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.

Full Text Available Curcumin is a natural anti-inflammatory agent that has been used for treating medical conditions for many years. Several experimental and pharmacologic trials have demonstrated its efficacy in the role as an anti-inflammatory agent. Curcumin has been shown to be effective in treating chronic conditions like rheumatoid arthritis, inflammatory bowel disease, Alzheimer's and common malignancies like colon, stomach, lung, breast, and skin cancers. As treatments in medicine become more and more complex, the answer may be something simpler. This is a review article written with the objective to systematically analyze the wealth of information regarding the medical use of curcumin, the “curry spice”, and to understand the existent gaps which have prevented its widespread application in the medical community.

Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) driven through altered immune responses with production of proinflammatory cytokines. Many therapies are used, but side effects and loss of response limit long-term effectiveness. New therapeutic strategies are thus needed for patients who don't respond to current treatments. Recently, there is suggested involvement of the proinflammatory hormone angiotensin II in inflammatory bowel disease. The aim of this study was to investigate the possible role of olmesartan medoxomil (OLM-M), an angiotensin II receptor blocker in ameliorating ulcerative colitis. Colitis was induced in male Wistar rats by administration of 5% dextran sodium sulphate (DSS) in drinking water for 5 days. OLM-M (1, 3 and 10 mg/kg) was administered orally during 21 days prior to the induction of colitis, and for 5 days after. Sulfasalazine (500 mg/kg) was used as reference drug. All animals were tested for changes in colon length, disease activity index (DAI) and microscopic damage. Colon tissue concentration/activity of tumor necrosis alpha (TNF-α), myeloperoxidase (MPO), prostaglandin E2 (PGE2), reduced glutathione (GSH) and malondialdehyde (MDA) were assessed. Results showed that the OLM-M dose-dependently ameliorated the colonic histopathological and biochemical injuries, an effect that is comparable or even better than that of the standard sulfasalazine. These results suggest that olmesartan medoxomil may be effective in the treatment of UC through its anti-inflammatory and antioxidant effects. - Highlights: • Olmesartan medoximil reduced dextran sodium sulphate- induced colitis. • Mechanism involved anti-inflammatory and antioxidant effects dose- dependently. • It suppressed malondialdehyde and restored reduced glutathione levels. • It reduced inflammatory markers levels and histological changes.

Inflammation has been implicated in the risk, pathophysiology, and progression of mood disorders and, as such, has become a target of interest in the treatment of bipolar disorder (BD). Therefore, the objective of the current qualitative and quantitative review was to determine the overall antidepressant effect of adjunctive anti-inflammatory agents in the treatment of bipolar depression. Completed and ongoing clinical trials of anti-inflammatory agents for BD published prior to 15 May 15 2015 were identified through searching the PubMed, Embase, PsychINFO, and Clinicaltrials.gov databases. Data from randomized controlled trials (RCTs) assessing the antidepressant effect of adjunctive mechanistically diverse anti-inflammatory agents were pooled to determine standard mean differences (SMDs) compared with standard therapy alone. Ten RCTs were identified for qualitative review. Eight RCTs (n = 312) assessing adjunctive nonsteroidal anti-inflammatory drugs (n = 53), omega-3 polyunsaturated fatty acids (n = 140), N-acetylcysteine (n = 76), and pioglitazone (n = 44) in the treatment of BD met the inclusion criteria for quantitative analysis. The overall effect size of adjunctive anti-inflammatory agents on depressive symptoms was -0.40 (95% confidence interval -0.14 to -0.65, p = 0.002), indicative of a moderate and statistically significant antidepressant effect. The heterogeneity of the pooled sample was low (I² = 14%, p = 0.32). No manic/hypomanic induction or significant treatment-emergent adverse events were reported. Overall, a moderate antidepressant effect was observed for adjunctive anti-inflammatory agents compared with conventional therapy alone in the treatment of bipolar depression. The small number of studies, diversity of agents, and small sample sizes limited interpretation of the current analysis. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Purpose To evaluate the pharmacokinetics and efficacy of topically applied nonsteroidal anti-inflammatory drugs (NSAIDs) in the retinochoroidal tissues of rabbits. Methods The cyclooxygenase (COX) inhibitory activity of diclofenac, bromfenac, and amfenac, an active metabolite of nepafenac, were determined using human-derived COX-1 and COX-2. Each of the three NSAIDs was applied topically to rabbits, and after 0.5 to 8 hrs, the concentration of each drug in the aqueous humor and the retinochoroidal tissues was measured by liquid chromatography-tandem mass spectrometry. The pharmacokinetics of the drugs in the tissues after repeated doses as is done on patients was calculated by a simulation software. The inhibitory effect of each NSAID on the breakdown of the blood-retinal barrier was assessed by the vitreous protein concentration on concanavalin A-induced retinochoroidal inflammation in rabbits. Results The half-maximal inhibitory concentration (IC50) of diclofenac, bromfenac, and amfenac was 55.5, 5.56, and 15.3 nM for human COX-1, and 30.7, 7.45, and 20.4 nM for human COX-2, respectively. The three NSAIDs were detected in the aqueous humor and the retinochoroidal tissue at all-time points. Simulated pharmacokinetics showed that the levels of the three NSAIDs were continuously higher than the IC50 of COX-2, as an index of efficacy, in the aqueous humor, whereas only the bromfenac concentration was continuously higher than the IC50 at its trough level in the retinochoroidal tissues. The intravitreous concentration of proteins was significantly reduced in rabbits that received topical bromfenac (P = 0.026) but not the other two NSAIDs. Conclusions Topical bromfenac can penetrate into the retinochoroidal tissues in high enough concentrations to inhibit COX-2 and exerts its inhibitory effect on the blood-retinal barrier breakdown in an experimental retinochoroidal inflammation in rabbits. Topical bromfenac may have a better therapeutic benefit than diclofenac and

Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most widely used drugs worldwide and represent a mainstay in the therapy of acute and chronic pain and inflammation. The traditional NSAIDs like ibuprofen (I) contain free carboxylic acid group which can produce gastrointestinal (GI) damage for long-term use. In order to obtain the novel NSAIDs with less side effects; carboxylic acid moiety has been modified into various amide groups which is the most active area of research in this family. In this research, synthesis of various pharmacological heterocyclic amides of ibuprofen is described. All the new compounds were tested for their analgesic and anti-inflammatory activities in mice and compared with standard (Ibuprofen) and control (saline) groups. The results revealed that all the synthesized compounds (III-VI) exhibited more analgesic and anti-inflammatory activities in tail immersion (as a model of acute thermal pain), formalin (as a model of acute chemical and chronic pain) and paw edema (as a model of acute inflammation) tests when compared with standard and control animals. These pharmacological activities were significant for VI compared to other new compounds (III-V) which may be concern to more effective role of morpholin for the reduction of pain and inflammation compared to other used heterocyclic amines.

Full Text Available Dolichos biflorus (Muthira is a branched, suberect, and downing herb, native to most parts of India, and found at altitudes of up to 1000 m, whose seeds can be cooked and eaten. Nutrition plays a key role in building immunity and preventing noncommunicable diseases to a certain extent. The purpose of this study was to evaluate the anti-inflammatory and antioxidant effects of 70% methanolic extract of seeds of D. biflorus (DME in carrageenan-induced inflammation. DME exhibited maximum percentage of oedema inhibition at a dose of 50 mg/kg at the 3rd hour of carrageenan induction. The effect was higher than that of the standard drug Voveran. The activities of cyclooxygenase, lipoxygenase, nitric oxide synthase, myeloperoxidase, and malondialdehyde showed significant (p < 0.05 reduction whereas the activities of antioxidant enzymes, vitamins C, and reduced glutathione level were increased significantly (p < 0.05 on treatment with DME. Also levels of the acute phase protein, ceruloplasmin, were brought to their normal range in DME-treated rats. Phytochemical analysis showed that the extract contains alkaloids, flavonoids, carbohydrates, proteins, and tannins, which may contribute to its anti-inflammatory and antioxidant activity. Thus the results demonstrate the potential beneficiary effect of DME on carrageenan-induced inflammation in rats.

Results of previous studies on the benefits of ocular drug delivery using polymeric mucoadhesive nanoparticles suggested longer presence and better penetration of nanoparticles, and, thus, increased effect and bioavailability of drugs entrapped in nanoparticles. In this study, a novel polymer, poly β-amino ester, was used for the preparation of triamcinolone acetonide-loaded nanoparticles using a modified emulsification/solvent diffusion method. Mucoadhesiveness studies, in vitro drug release, x-ray powder diffraction, differential scanning calorimetry, and scanning electron microscopy were used for physicochemical characterization of nanoparticles. Thirty-six hours after inducing uveitis by intravitreal injection of a lipopolysaccharide, sampling from the aqueous humor was done and inflammatory factors, such as cell, protein, nitric oxide, and prostaglandin E2, were compared. Nanoparticles with a mean size of 178 nm and drug loading of 5.3% were prepared and used for in vivo studies in rabbits with uveitis. Higher anti-inflammatory effect was observed for polymeric nanoparticles of triamcinolone acetonide compared with microparticles of prednisolone acetate and triamcinolone acetonide, and an equal effect compared with subconjunctival injection of triamcinolone acetonide in terms of inhibiting inflammation and inflammatory mediators. It can be concluded that polymeric nanoparticles of triamcinolone acetonide will provide as good an anti-inflammatory effect as the subconjunctival injection method and are better compared with other drug delivery systems.

Charge transfer (CT) complexes of some non-steroidal anti-inflammatory drugs, naproxen and etodolac which are electron donors with some π-acceptors, such as tetracyanoethylene (TCNE), 2,3-dichloro-5,6-dicyano- p-benzoquinone (DDQ), p-chloranil ( p-CHL), have been investigated spectrophotometrically in chloroform at 21 °C. The coloured products are measured spectrophotometrically at different wavelength depending on the electronic transition between donors and acceptors. Beer's law is obeyed and colours were produced in non-aqueous media. All complexes were stable at least 2 h except for etodolac with DDQ stable for 5 min. The equilibrium constants of the CT complexes were determined by the Benesi-Hildebrand equation. The thermodynamic parameters Δ H, Δ S, Δ G° were calculated by Van't Hoff equation. Stochiometries of the complexes formed between donors and acceptors were defined by the Job's method of the continuous variation and found in 1:1 complexation with donor and acceptor at the maximum absorption bands in all cases.

In this study the anti-inflammatory potential of potassium humate, derived from bituminous coal, has been investigated in vitro. Exposure of resting and phorbol-12-myristate-13-acetate (PMA) stimulated human neutrophils to potassium humate resulted in a decreased expression of CR3 by activated, but not resting cells, in a dose-related way. Humate also inhibited the adhesion of PMA-stimulated neutrophils to a baby hamster kidney cell line expressing ICAM1 (the CR3 ligand) (BHK331-7). Similar results were obtained using normal BHK cells indicating that this inhibition does not only target specific adhesion molecules on the neutrophil and eosinophil membrane by activated phagocytes, but also affects other mechanisms involved in cell adhesion. Opsonised Sephadex or FMLP/Cyto B-induced degranulation of neutrophils and eosinophils were also decreased by humate treatment. Inhibition of the adhesion of activated phagocytes, as well as inhibition of the release of granule polypeptides, both of which are responsible for tissue damage during inflammatory processes, are attractive targets for anti-inflammatory drugs. Because humate is well tolerated with an excellent safety profile it merits further evaluation in patients suffering from inflammatory conditions.

In vivo immune signatures of healthy human pregnancy: Inherently inflammatory or anti-inflammatory?

Full Text Available Changes in maternal innate immunity during healthy human pregnancy are not well understood. Whether basal immune status in vivo is largely unaffected by pregnancy, is constitutively biased towards an inflammatory phenotype (transiently enhancing host defense or exhibits anti-inflammatory bias (reducing potential responsiveness to the fetus is unclear. Here, in a longitudinal study of healthy women who gave birth to healthy infants following uncomplicated pregnancies within the Canadian Healthy Infant Longitudinal Development (CHILD cohort, we test the hypothesis that a progressively altered bias in resting innate immune status develops. Women were examined during pregnancy and again, one and/or three years postpartum. Most pro-inflammatory cytokine expression, including CCL2, CXCL10, IL-18 and TNFα, was reduced in vivo during pregnancy (20-57%, p<0.0001. Anti-inflammatory biomarkers (sTNF-RI, sTNF-RII, and IL-1Ra were elevated by ~50-100% (p<0.0001. Systemic IL-10 levels were unaltered during vs. post-pregnancy. Kinetic studies demonstrate that while decreased pro-inflammatory biomarker expression (CCL2, CXCL10, IL-18, and TNFα was constant, anti-inflammatory expression increased progressively with increasing gestational age (p<0.0001. We conclude that healthy resting maternal immune status is characterized by an increasingly pronounced bias towards a systemic anti-inflammatory innate phenotype during the last two trimesters of pregnancy. This is resolved by one year postpartum in the absence of repeat pregnancy. The findings provide enhanced understanding of immunological changes that occur in vivo during healthy human pregnancy.

Full Text Available Objective: to substantiate the importance of an etiological approach to diagnosing urinary tract infection in children in terms of the species and biological properties of an infectious agent and to evaluate the efficiency of anti-inflammatory therapy. The study included 116 patients aged 3-15 years with chronic pyelonephritis (Group 1 and isolated bacteriuria (Group 2. After 10-14-day antibiotic therapy, Group 1 patients were allocated to two subgroups: Subgroup la («=30 took furamag 5 mg/kg/day; Subgroup lb («=30 received furamag at the same dose in combination with canephron. The treatment cycle lasted 10-14 days. Subgroup 2a («=26 children had furamag 5 mgДg/day and Subgroup 2b (« =30 took furamag in combination with canephron. The duration of treatment was 14 days. The investigators established the high efficiency of therapy with furamag for renal infection in the children with the active and decrement phases and that of the drug of choice for its monotherapy of isolated highly virulent bacteriuria. Therapeutic efficiency was proven to be related to the species and biological characteristics of an infectious agent. Anti-inflammatory therapy for pyelonephritis in terms of the species of pathogenic bacteria was ascertained to improve the efficiency of treatment. A rationale was provided for the individual choice of antibiotics, followed by the use of furamag, eubiotics, and drugs aimed at inhibiting virulence factors and persistence of the pathogen to sanitize the primary focus of infection.

Nonsteriodal anti-inflammatory drugs (NSAIDs) are numerous and widely used for more than 60 years, but there is still a strong need for developing novel selective NSAIDs. The need is justified by the fact that nonselective NSAIDs can produce serious gastric side effects and that some of the selective NSAID are withdrawn due to their cardiotoxic side effects. Eight β-hydroxy-β-arylpropanoic acids, which belong to the arylpropanoic acid class of compounds, structurally similar to some nonsteroidal anti-inflammatory drugs (NSAIDs), were docked into 3D catalytic site of both cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2). Seven out of those eight acids were synthesized using already published modification of Reformatsky reaction additionally optimized by increasing temperature. Synthesized compounds were tested in vivo in order to elucidate anti-inflammatory activity, gastric tolerability and impact on liver function of rats. Results of docking studies have indicated that all compounds have potential to selectively inhibit COX-2 isoform, but that the compounds containing polar substituents on phenyl ring are better inhibitors. Results of carrageenan-induced rat paw oedema test have shown that all compounds exhibit dose dependence and good gastric tolerability and none of the tested compounds have shown negative effect on liver function compared to ibuprofen. The compound containing polar nitro group in para position has shown the best docking results, anti-inflammatory activity, low hepatotoxicity and good gastric tolerability.

Full Text Available Background. Inflammation and pain are closely related to humans’ and animals’ health. Resveratrol (RSV is a natural compound with various biological activities. The current study is aimed to evaluate the analgesic and anti-inflammatory activities of RSV in vivo. Materials and Methods. The analgesic effects were assessed by the acetic acid-induced writhing and hot plate tests. The anti-inflammatory effects were determined using the xylene-induced mouse ear oedema, the acetic acid-induced rat pleurisy, and carrageenan-induced rat synovitis tests, respectively. Results. The analgesic results showed that RSV could significantly inhibit the number of writhes and improve the time and pain threshold of mice standing on hot plate. The anti-inflammatory results showed that RSV could inhibit the ear oedema of mice. In acetic acid-induced pleurisy test, RSV could significantly inhibit the WBC and pleurisy exudates, could decrease the production of NO, and elevate the activity of SOD in serum. In carrageenan-induced synovitis test, RSV could reduce the content of MDA and elevate the T-SOD activity in serum; RSV could inhibit the expressions of TP, PGE2, NO, and MDA. Conclusion. Shortly, these results indicated that RSV had potent analgesic and anti-inflammatory activities and could be a potential new drug candidate for the treatment of inflammation and pain.

Objective: Berberis aristata (Berberidaceae) is an important medicinal plant used in traditional system of medicine for the treatment of rheumatoid arthritis and other inflammatory disorders. The aim of the present study is to scientifically validate the traditional use of BA in the treatment of inflammatory disorders. Materials and Methods: Anti-inflammatory and anti-granuloma activity of BA hydroalcoholic extract (BAHE) were evaluated in experimental models, viz., carrageenan-induced paw edema, cotton pellet-induced granuloma formation, and complete Freund's adjuvant-induced stimulation of peritoneal macrophages in rats. Expression of inflammatory mediators, viz., tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), IL-6, IL-10, TNF-R1, and cyclooxygenase-2 (COX-2) was carried out in serum and peritoneal macrophages to derive the plausible mechanism of BAHE in activated peritoneal macrophages. Results: Pretreatment with BAHE produced a dose-dependent reduction (P < 0.01) in carrageenan-induced paw edema and cotton pellet-induced granuloma model. BAHE treatment produced significant (P < 0.01) reduction in serum inflammatory cytokine levels as compared to control. Protein expression of pro-inflammatory markers, IL-1β, IL-6, TNF-R1, and COX-2, was found to be reduced in stimulated macrophages whereas anti-inflammatory cytokine, IL-10, was upregulated in peritoneal macrophages. Conclusion: The result of the present study thus demonstrates the anti-inflammatory and anti-granuloma activity of BAHE which may be attributed to its inhibitory activity on macrophage-derived cytokine and mediators.

Many parts of Musa sapientum Linn. (Musaceae) are used in Thai traditional medicine as drugs, food supplements and cosmetics. The banana peel is used as an astringent in foot care, the unripe fruit is used to treat diarrhea and, the ripe fruit is used as tonic. To evaluate anti-inflammatory and antioxidant activities of banana peel extracts obtained from different extraction methods and to determine their total phenolic content. Four extraction methods were used to extract unripe and ripe peels. Nitric oxide inhibitory and DPPH scavenging assays were used to evaluate anti-inflammatory and antioxidant activities, respectively. Folin-Ciocalteu's reagent was used to determine total phenolic content. The water extract of fresh ripe peel exhibited the most potent NO inhibitory activity (IC50 = 6.68 +/- 0.34 microg/ml), but apparently exhibited no antioxidant activity. The decoction extract of fresh unripe peel exhibited strong antioxidant activity as well as had the highest total phenolic compound. The antioxidant activity exhibited a correlation with the total phenolic content. This study supports the use of Musa sapientum peel in Thai Traditional Medicine for treatment of inflammatory-related diseases.

Habb (Pill) is one of the important dosage forms of Unani system of medicine. A number of effective formulations are manufactured in form of Habb because of its various advantages. Out of these, Habbe Irqun Nisa (HI) is a popular anti-inflammatory formulation used in the treatment of Warame Mafasil (arthritis) and Irqun Nisa (sciatica). Nowadays, with increased incidence of these diseases many non-steroidal anti-inflammatory drugs (NSAIDs) are being used in their treatment. Owing to the adverse effects of these drugs, the use of herbal medicines is seen as a better alternative. The basic requirement for the development of Unani system of Medicine is the standardization of single and compound drugs. HI is mentioned in National Formulary of Unani Medicne and selected for the present study. HI was prepared manually with the powder of crude drugs, passed through sieve no. 100 and mixed with 1% w/w of gum acacia in mucilage form. It was then dried at 60°C for 90 min and then tested for its standardization on different physicochemical parameters, e.g. organoleptic properties, pH values, moisture content, ash values, friability, hardness, weight variation, disintegration time, and thin layer chromatography (TLC). The data evolved from this study will make it a validated product and will help in the quality control of other finished products in future research.

A clinical study was performed on 18 healthy volunteers to compare the gastrointestinal daily blood loss induced by oral intake of three different non-steroidal anti-inflammatory drugs, lysine clonixinate (CAS 55837-30-4), ibuprofen (CAS 15687-27-1) and acetylsalicylic acid (CAS 50-78-2 ASA). For quantitative determination of gastrointestinal blood loss, autologous erythrocytes were radiolabelled in vitro with 51Cr and reinfused at study start. The amount of radioactivity excreted in faeces was measured during a placebo baseline phase of three days, a treatment phase of five days with thrice daily dosing of ASA, ibuprofen or lysine clonixinate and a subsequent wash-out phase of five days. The highest increase of mean daily blood loss over baseline was observed after treatment with ASA (+ 1.66 ml/d versus baseline). Treatment with ibuprofen led to an increase of mean daily blood loss by + 0.52 ml/d. During treatment with lysine clonixinate the mean increase of daily blood loss was +0.32 ml/d versus baseline. In the ibuprofen and lysine clonixinate treatment groups the values of mean daily blood loss decreased during the wash-out phase with respect to the verum phase, whereas the mean daily blood loss during the wash-out phase after treatment with ASA even increased in comparison to the verum phase (mean daily blood loss: +2.07 ml/d versus baseline.

Neuro-immune interactions via the cholinergic anti-inflammatory pathway

Gallowitsch-Puerta, Margot; Pavlov, Valentin A.

2010-01-01

The overproduction of TNF and other cytokines can cause the pathophysiology of numerous diseases. Controlling cytokine synthesis and release is critical for preventing unrestrained inflammation and maintaining health. Recent studies identified an efferent vagus nerve-based mechanism termed “the cholinergic anti-inflammatory pathway” that controls cytokine production and inflammation. Here we review current advances related to the role of this pathway in neuro-immune interactions that prevent excessive inflammation. Experimental evidence indicates that vagus nerve cholinergic anti-inflammatory signaling requires alpha7 nicotinic acetylcholine receptors expressed on non-neuronal cytokine producing cells. Alpha7 nicotinic acetylcholine receptor agonists inhibit cytokine release and protect animals in a variety of experimental lethal inflammatory models. Knowledge related to the cholinergic anti-inflammatory pathway can be exploited in therapeutic approaches directed towards counteracting abnormal chronic and hyper-activated inflammatory responses.

Angiogenesis or neovascularization, the formation of neo-vessels, is a physiological phenomenon endued in vasculature, but is involved in various pathological conditions. Angiogenesis is required for tumor growth and metastasis, and thus constitutes an important target for the control of tumor progression. Indeed, the recent development of bevacizumab, a neutralizing anti-VEGF monoclonal antibody as the first anti-angiogenic drug, legalized the clinical merit of anti-angiogenesis in cancers. Thereafter, various drugs targeting VEGF-mediated signals have been developed to control tumor angiogenesis. Thus, anti-angiogenic drugs are now recognized in the clinic as a major step forward for the treatment of cancers. This review focuses on the current status of antiangiogenesis treatment in cancers.

Lactuca sativa (lettuce) has been traditionally used for relieving pain, inflammation, stomach problems including indigestion and lack of appetite. Moreover, the therapeutic significance of L. sativa includes its anticonvulsant, sedative-hypnotic and antioxidant properties. In the present study, the MC (methanol and chloroform; 1:1) and aqueous extracts of seed and leaf along with cell suspension exudate were prepared. These extracts were explored for their analgesic, anti-inflammatory, antidepressant and anticoagulant effects by hot plate analgesic assay; carrageenan induced hind paw edema test, forced swimming test and capillary method for blood clotting respectively in a rat model. The results were analyzed using one-way Analysis of Variance (ANOVA) followed by Turkey multiple comparison test. Interestingly, the extracts and the cell suspension exudate showed dual inhibition by reducing pain and inflammation. The results indicated that the aqueous extracts of leaf exhibited highest analgesic and anti-inflammatory activities followed by leaf MC, cell suspension exudate, seed aqueous and seed MC extracts. The current findings show that aqueous and MC extracts of seed have the least immobility time in the forced swimming test, which could act as an anti-depressant on the central nervous system. The leaf extracts and cell suspension exudate also expressed moderate anti-depressant activities. In anticoagulant assay, the coagulation time of aspirin (positive control) and MC extract of leaf was comparable, suggesting strong anti-coagulant effect. Additionally, no abnormal behavior or lethality was observed in any animal tested. Taken together, L. sativa can potentially act as a strong herbal drug due to its multiple pharmaceutical effects and is therefore of interest in drug discovery and development of formulations.

To determine anti-inflammatory and anti-cancer activities of Cuscuta reflexa in cell lines (in vitro). Anti-inflammatory activity of the water extract was analysed in vitro using lipopolysaccharide (LPS) induced inflammatory reactions in murine macrophage cell line RAW264.7. The expression of COX-2 and TNF-α genes involved in inflammation was analysed by SQ RT-PCR. EMSA was conducted to analyse the influence of the extract on NF-κB signalling. Anti-cancer activity was analysed on Hep3B cells by MTT assay, DAPI staining, annexin V staining and SQ-RT PCR analysis of BAX, Bcl-2, p53 and survivin. The extract down regulated LPS induced over expression of TNF-α and COX-2 in RAW264.7 cells; blocked NF-κB binding to its motifs and induced apoptosis in Hep3B cells as evidenced from MTT, DAPI staining and annexin V staining assays. The extract up regulated pro-apoptotic factors BAX and p53, and down regulated anti-apoptotic factors Bcl-2 and survivin. The study showed that Cuscuta reflexa inhibits LPS induced inflammatory responses in RAW264.7 cells through interplay of TNF-α, COX-2 and NF-κB signalling. It induced apoptosis in Hep3B cells through the up regulation of p53, BAX and down regulation of Bcl-2 and survivin. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.
