The IHO as Actor The case of cannabis and the Single Convention on Narcotic Drugs 1961

Directory of Open Access Journals (Sweden)

James H. Mills

2016-12-01

Full Text Available After the Second World War the United Nations (UN assumed the role of the League of Nations in formulating and operating the international regulatory framework for narcotic drugs. It gathered masses of information from across countries and continents while acting as both a forum and an agent for the emergence of agreed approaches to a heterodox array of substances. This article will examine the story of the inclusion of cannabis in the 1961 Single Convention on Narcotic Drugs. It will argue that in the years after 1945, it was officials at the UN and the WHO that played crucial roles in shaping opinions of the drug and in securing its place in the Convention.

Introduction: Immunosensor for illicit drugs have gained immense interest and have found several applications for drug abuse monitoring. This technology has offered a low cost detection of narcotics; thereby, providing a confirmatory platform to compliment the existing analytical methods. Methods: In this minireview, we define the basic concept of transducer for immunosensor development that utilizes antibodies and low molecular mass hapten (opiate) molecules. Results: This article emphasizes on recent advances in immunoanalytical techniques for monitoring of opiate drugs. Our results demonstrate that high quality antibodies can be used for immunosensor development against target analyte with greater sensitivity, specificity and precision than other available analytical methods. Conclusion: In this review we highlight the fundamentals of different transducer technologies and its applications for immunosensor development currently being developed in our laboratory using rapid screening via immunochromatographic kit, label free optical detection via enzyme, fluorescence, gold nanoparticles and carbon nanotubes based immunosensing for sensitive and specific monitoring of opiates.

An immunoassay based technique is used for the detection of psychoactive substances in the sweat deposited within fingermarks of a narcotic drug user. Magnetic particles functionalized with antimorphine and antibenzoylecgonine antibodies were used for the detection of a metabolite of heroin (morphine) and a metabolite of cocaine (benzoylecgonine), respectively. The drug metabolites were detected individually as well as simultaneously from a single fingermark. The images of the fingermarks obtained using brightfield and fluorescence microscopy were of high evidential quality with resolution to enable identification of an individual in addition to providing information on drug usage.

Fast analysis of narcotic drugs by optical chemical imaging

International Nuclear Information System (INIS)

Fisher, Michal; Bulatov, Vallery; Schechter, Israel

2003-01-01

A new technique is proposed for fast detection, identification and imaging of narcotic drugs in their solid phase. This technique, which requires only a tiny sample of a few microns, is based on microscopic chemical imaging. Minor sample preparation is required, and results are obtained within seconds. As far as we know, this is the most sensitive detection system available today for solid drugs. The technique can be applied for fast analysis of minute drug residues, and therefore is of considerable importance for forensic applications. It is shown that identification of drug traces in realistic matrixes is possible. Two main methods were applied in this study for detection of drugs and drug derivatives. The first method was based on direct detection and chemical imaging of the auto-fluorescence of the analyzed drugs. This method is applicable when the analyzed drug emits fluorescence under the experiment conditions, such as lysergic acid diethylamide (known as LSD). The second method was used for obtaining chemical imaging of drugs that do not fluoresce under the experiment conditions. In these cases fluorescent labeling dyes were applied to the examined samples (including the drug and the matrix). Both methods are simple and rapid, and require minor or no sample preparation at all. Detection limits are very low in the picogram range

The total mass attenuation coefficients (μ/ρ), total molecular (σt,m), atomic (σt,a) and electronic (σt,e) cross sections, effective atomic numbers (Zeff) and electron density (NE) were computed in the wide energy region from 1 keV to 100 GeV for the selected narcotic drugs such as morphine, heroin, cocaine, ecstasy and cannabis. The changes of μ/ρ, σt,m, σt,a, σt,e, Zeff and NE with photon energy for total photon interaction shows the dominance of different interaction process in different energy regions. The variations of μ/ρ, σt,m, σt,a, σt,e, Zeff and NE depend on the atom number, photon energy and chemical composition of narcotic drugs. Also, these parameters change with number of elements, the range of atomic numbers in narcotic drugs and total molecular weight. These data can be useful in the field of forensic sciences and medical diagnostic.

Antecedents of narcotic use and addiction. A study of 898 Vietnam veterans.

Helzer, J E; Robins, L N; Davis, D H

1976-02-01

Previous studies of predictors of narcotic abuse have been retrospective and based on samples of long-term addicts obtained from legal or medical channels. There are several methodological problems in this approach. The present study is an attempt to test certain alleged predictors of narcotic use in a cohort of 898 Vietnam veterans. The design overcomes several of the methodological weaknesses of previous studies. Eight variables which have been reported as predictors of drug use or addiction in the drug literature were inquired about during a personal interview which included the premilitary life of each subject. The antecedent variables were socioeconomic background, inner city residence, psychiatric illness, broken home, race, employment history, education and antisocial history. Using information obtained from interviews and military records, we then tested the predictive value of each of these antecedents by comparing narcotic used and addiction in Vietman and use after Vietnam in men differing with respect to each antecedent. Results indicate that some of the variables were very poor, and others very good predictors of the various levels of narcotic involvement. The predictive value and overall importance of each of the variables we tested are discussed.

THE EFFECT OF ILLICIT TRADE IN NARCOTICS ON GLOBAL ECONOMY

Directory of Open Access Journals (Sweden)

ALASMARI Khaled

2013-07-01

Illicit markets especially those dealing with narcotics constitute grievous issues to the world’s economies, putting to test global safety, economic progress as well as security and many other aspects. Seemingly, illicit narcotics trade in the last decade – that is 2000 to 2011 underwent a significant boom, resulting from a wide spectrum of illegal drugs such as cocaine as well as heroin among many other hard drugs. In today’s global society, several concerns are emerging on the rise of illicit narcotics trade accompanied with organized crime, chiefly as major hindrances to consistent global economic progress. Apparently, some of the effects of illicit narcotics trade are that; this trade gradually turns upside down business rules, opening way for new unruly market players besides reconfiguring influence in global economics as well as politics. Surprisingly, the revenue from illegal drugs in 2011 alone was roughly 10% of the global GDP. Hence, exaggerating local economies’ incomes and triggering ceaseless conflicts among market players, while at the same time reducing legal business activities likewise disintegrating socioeconomic conditions. An empirical research method was adopted for this study, analyzing illicit trade in narcotics on the global arena as from 2000 to 2011 and its resultant effects. The research findings indicate that, illegal drugs trade particularly on the world economy besides growing at a high rate, it endangers the overall welfare of humans likewise the business environment. This is ostensibly because this trade has high chances of engrossing regional economies into illegal drugs business activities, causing them to neglect sustainable ethical businesses. Now, to effectively address negative economic issues related to illegal drugs trade, there is apparent need for integrated efforts from local as well as international authorities. Such efforts are chiefly to control not only the harmful effects resulting from the use of illicit

Full Text Available Aim: To determine the extent to which nurses are able to correctly identify drugs as narcotics and to ascertain their perception of the addiction potential of opiates when used for pain management. Methods: A questionnaire was administered to 86 nurses who attended palliative care workshops in India. Findings: Only morphine (95%, heroin (71% and codeine (75% were correctly identified as narcotics by the majority of participants. Imipramine (34%, diazepam (20% and phenobarbitone (39% were wrongly classified as narcotics by many nurses. Dextropropoxyphene (11%, pentazocine (21%, buprenorphine (15% were correctly classified as narcotics by fewer than half the participants. Only 14% knew that that the frequency of psychological dependence due to use of morphine for cancer pain was less than 1%.

Individuals with certain personality disorders, especially the antisocial and borderline personality disorders, are more prone to substance use disorders. Regarding the importance of substance use disorders, this study aimed to explore the association between personality disorders and types of used drugs (narcotics and stimulants) in Iranian male substance users. The current study was a correlation study. We evaluated 285 male substance users and excluded 25 according to exclusion criteria. A total of 130 narcotic users and 130 stimulant users were recruited randomly in several phases from January 2013 to October 2013. All participants were referred to Substance Dependency Treatment Clinics in Tehran, Iran. Data collection process was accomplished by means of clinical interview based on DSM-V criteria for substance use disorders, Iranian version of addiction severity index (ASI), and Millon clinical multi-axial inventory-III (MCMI-III). Data were analyzed by SPSS 21 using Pearson correlation coefficient and regression, the. There was a significant correlation between stimulant use and histrionic personality disorder (P personality disorders (P histrionic, and narcissistic personality disorders (P personality disorders (P personality disorders, and narcotic and stimulants consumption (P personality disorder and narcotics (P personality disorders and types of used drugs were in accordance with the previous studies results. It is necessary to design appropriate treatment plans for medical treatment of those with personality disorders.

On the basis of analysis of 1,879 samples of narcotics confiscated in Jutland and Funen during the period 1981-1988, the individual types of drugs are described as regards occurrence and quality. Cannabis and heroin were found in the illegal market during the entire period. Amphetamine was rarely observed prior to 1985 but comprised half of the illegal drugs examined in 1988. Cocaine was encountered in only 1% of the samples. Designer drugs were not seen. Heroin occurred relatively most frequently in Aarhus, Odense and Esbjerg while amphetamine and cannabis were found in all parts of Jutland and Funen. The samples of heroin and amphetamine varied greatly as regards strength and the types and quantities of cutting agents. The majority of the samples were adulterated and/or diluted with substances such as caffeine and phenazone and the sugars, glucose and lactose.

Development of a portable preconcentrator/ion mobility spectrometer system for the trace detection of narcotics

Energy Technology Data Exchange (ETDEWEB)

Parmeter, J.E.; Custer, C.A.

1997-08-01

This project was supported by LDRD funding for the development and preliminary testing of a portable narcotics detection system. The system developed combines a commercial trace detector known as an ion mobility spectrometer (IMS) with a preconcentrator originally designed by Department 5848 for the collection of explosives molecules. The detector and preconcentrator were combined along with all necessary accessories onto a push cart, thus yielding a fully portable detection unit. Preliminary testing with both explosives and narcotics molecules shown that the system is operational, and that it can successfully detect drugs as marijuana, methamphetamine (speed), and cocaine based on their characteristics IMS signatures.

Full Text Available Abstract Simultaneous bilateral femoral neck fractures are extremely rare and associated with various conditions. Up to now Most cases had correlations with major trauma, repetitive minor trauma, seizure, parathyroid or renal dysfunction, anti-epileptic medications, seizure, etc. A 28-year-old addict man referred to us with a 10-year history of narcotic drug abuse and history of 8 months bilateral groin pain. He admitted with displaced bilateral femoral neck fracture. Because of long duration of this condition and osteonecrosis revealed on bone scan, one-staged bilateral hip hemiarthroplasty was done. A good function was noted after surgery to 4-month follow up. Up to now, have not be founded in the literature that a case of bilateral femoral neck fracture associated with narcotic drug abuse. Because of negative effects of opium or smoking on bone tissues, a simple bone pain should aware us about the risk of stress or fatigue fracture.

2013-04-01

Effective atomic numbers for photon energy absorption ZPEA,eff, photon interaction ZPI,eff and for electron density Nel, have been calculated by a direct method in the photon-energy region from 1 keV to 20 MeV for narcotic drugs, such as Heroin (H), Cocaine (CO), Caffeine (CA), Tetrahydrocannabinol (THC), Cannabinol (CBD), Tetrahydrocannabivarin (THCV). The ZPEA,eff, ZPI,eff and Nel values have been found to change with energy and composition of the narcotic drugs. The energy dependence ZPEA,eff, ZPI,eff and Nel is shown graphically. The maximum difference between the values of ZPEA,eff, and ZPI,eff occurs at 30 keV and the significant difference of 2 to 33% for the energy region 5-100 keV for all drugs. The reason for these differences is discussed.

New Challenges in the Narcotics World

Directory of Open Access Journals (Sweden)

Nicoleta-Elena Buzatu

2011-05-01

Full Text Available The consumption of narcotics is one of the problems the international world is confronted withnowadays; its direct or indirect effects lead to the conclusion that it represents a worrying phenomenon meantto be taken into account by the international programs of co-operation. In contrast with the mature population,the younger population is much more receptive to the new, much more attracted by new experiments and,consequently, by risks. The narcotics flagellum is one of the most complex, profound and dramaticphenomena met with in the contemporary world. Narcotization is the morbid habit of repeatedly taking andusing ever higher doses of more or less toxic substances able to generate a psychological and physicaladdiction to them. Unhappily due to the lack of information, people think that the illegal substances only –heroine, marijuana, cocaine, etc. – are considered drugs. Not long ago there appeared the so-called “mixes ofethno-botanical plants” that are perfectly legal, and many consumers have replaced narcotics - as marijuana,for example - with plant mixes. According to explanations given by the Ethno-botanical ExplanatoryDictionary, ethno-biology is a branch that studies the mutual relationship between man and plant. InRomania, ethno-botanical plants are sold under the generic names of “aroma therapeutic” or “ethnobotanical”plants. The numerous researches meant to decode the molecular and biochemical structure of theseherbs, the researchers found that consumers are described as facing hallucinogenic effects caused by somesynthetic substances - cannabinoids - added by manufacturers.

Pain control after traumatic rib fracture is essential to avoid respiratory complications and prolonged hospitalization. Narcotics are commonly used, but adjunctive medications such as nonsteroidal anti-inflammatory drugs may be beneficial. Twenty-one patients with traumatic rib fractures treated with both narcotics and intravenous ibuprofen (IVIb) (Treatment) were retrospectively compared with 21 age- and rib fracture-matched patients who received narcotics alone (Control). Pain medication requirements over the first 7 hospital days were evaluated. Mean daily IVIb dose was 2070 ± 880 mg. Daily intravenous morphine-equivalent requirement was 19 ± 16 vs 32 ± 24 mg (P pain scores were lower in the Treatment group (P rib fractures significantly decreases narcotic requirement and results in clinically significant decreases in hospital length of stay. IVIb therapy should be initiated in patients with traumatic rib fractures to improve patient comfort and reduce narcotic requirement.

Prescription of the High Risk Narcotics and Trading or Illicit Purchasing of High Risk Narcotics

Directory of Open Access Journals (Sweden)

Nicoleta-Elena Buzatu

2012-05-01

Full Text Available The present essay will analyze the offence of prescribing high risk narcotics and trading or illicit purchasing of high risk narcotics, as it was regulated - together with other offences - by Law no 143 of July 26, 2000 on preventing and fighting against the traffic and illicit consumption of narcotics. The same law defines the meaning of such a phrase “substances which are under national control” by mentioning the fact that they are the narcotics and their precursors listed in Annexes I-IV of the law. The analysis of the offence of prescribing the high risk narcotics and trading or illicit purchasing of high risk narcotics is following the already known structure mentioned in the doctrine and which consists of: object and subjects of the offence, its constituent content: the objective side with its material element, the immediate consequence and causality connections; the subjective side of the offence, as well as forms and modalities of these offences, and the applicable sanctions, of course.

Unused/unwanted medications in households and patient care facilities expose vulnerable populations, including children, elders, and pets, to potential harm through inadvertent ingestion, as well as the potential for theft and assault. Hawai'i Administrative Rules prohibit the return of any prescription medications to retail pharmacies after dispensing. The Hawai'i Narcotics Enforcement Division (NED) partnered with the University of Hawai'i at Hilo Daniel K. Inouye College of Pharmacy (CoP) in eleven Drug Take Back events throughout the state. Most participants heard of the events via newspaper and television marketing. The most common methods of medication disposal are via trash or down household drains. Over 8,000 lbs of unused/unwanted medications was collected, identified and logged from 2011 through 2012. The majority of returned drugs were non-controlled substances (90%). Commonly returned medications included prescription cardiac medications such as simvastatin and lisinopril, non-prescription analgesics such as aspirin and ibuprofen, and dietary supplements such as vitamins and iron. Commonly returned controlled substance medications included narcotics such as hydrocodone/acetaminophen combinations and oxycodone, and sedative hypnotics such as zolpidem and lorazepam.

Birth order and hospitalization for alcohol and narcotics use in Sweden.

2016-10-01

Previous studies have shown that birth order is an important predictor of later life health as well as socioeconomic attainment. In this study, we examine the relationship between birth order and hospitalization for alcohol and narcotics use in Sweden. We study the relationship between birth order and hospitalization related to alcohol and narcotics use before and after the age of 20 using Swedish register data for cohorts born 1987-1994. We apply Cox proportional hazard models and use sibling fixed effects, eliminating confounding by factors shared by the siblings. Before age 20 we find that later born siblings are hospitalized for alcohol use at a higher rate than first-borns, and there is a monotonic increase in the hazard of hospitalization with increasing birth order. Second-borns are hospitalized at a rate 47% higher than first-borns, and third-borns at a rate 65% higher. Similar patterns are observed for hospitalization for narcotics use. After age 20 the pattern is similar, but the association is weaker. These patterns are consistent across various sibling group sizes. Later born siblings are more likely to be hospitalized for both alcohol and narcotics use in Sweden. These birth order effects are substantial in size, and larger than the estimated sex differences for the risk of hospitalization related to alcohol and drug use before age 20, and previous estimates for socioeconomic status differences in alcohol and drug abuse.

IMPLEMENTATION OF DRUG ADDICTS RIGHT TO HEALTH PROTECTION (SEPARATE ASPECTS).

Science.gov (United States)

Shevchuk, O; Rzhevska, O; Korop, O; Pyliuha, L

2018-03-01

The purpose of the research is to analyze specific problems of the realization of the right to protect the health of people who take narcotic drugs or psychotropic substances. To achieve this goal, statistics have been analyzed on the number of people using narcotic drugs or psychotropic substances (including drug-addicted children) placed on medical records and the number of their applications for medical care. It has been found out that people in this category often face a denial of medical care that causes extremely strong physical and mental suffering. The analysis of the understanding of the legal design of the «right to health care» in the scientific literature, national legislation and international legal documents was made. State institutions and local authorities providing «the right to health care» of people taking narcotic or psychotropic drugs are singled out. The absence of grounds for restricting the right to protect the health of people who take narcotic or psychotropic drugs who are not registered is justified. In the course of the research, it was found out that people who take narcotic drugs or psychotropic substances are more likely than other patients to need medical assistance and, when requesting the right to health care, face a number of problems that require immediate solution: incomplete provision of quality free medical care; unimplementation of rehabilitation programs for such categories of patients; the lack of the right of children who take narcotic drugs or psychotropic substances to make their own decisions at the age of 14 and apply to public health institutions for the treatment of drug addiction; violations of the continuity of SMT programs and their absence in penal institutions for drug dependent people. It was proposed to introduce a number of changes in the relevant normative legal acts.

Transcultural use of narcotic water lilies in ancient Egyptian and Maya drug ritual.

Emboden, W A

1981-01-01

Comparisons are made between ancient ritual uses of the flowers of Nymphaea (Nymphaeaceae) in Maya and Egyptian civilizations. Recurrent motifs encountered in the art of both of these ancient civilizations suggests that the role fo the water lily was that of a narcotic (psychodysleptic) used to mediate ecstasis among a priestly caste. Relevant literature is reviewed as are chemical data. Elements in the complex belief systems of these two civilizations need to be reinterpreted in view of the use of two water lilies as ritual narcotics. The species implicated are Nymphaea caerulea Sav., in Egypt, and N. ampla DC., among the Maya.

Unused/unwanted medications in households and patient care facilities expose vulnerable populations, including children, elders, and pets, to potential harm through inadvertent ingestion, as well as the potential for theft and assault. Hawai‘i Administrative Rules prohibit the return of any prescription medications to retail pharmacies after dispensing. The Hawai‘i Narcotics Enforcement Division (NED) partnered with the University of Hawai‘i at Hilo Daniel K. Inouye College of Pharmacy (CoP) in eleven Drug Take Back events throughout the state. Most participants heard of the events via newspaper and television marketing. The most common methods of medication disposal are via trash or down household drains. Over 8,000 lbs of unused/unwanted medications was collected, identified and logged from 2011 through 2012. The majority of returned drugs were non-controlled substances (90%). Commonly returned medications included prescription cardiac medications such as simvastatin and lisinopril, non-prescription analgesics such as aspirin and ibuprofen, and dietary supplements such as vitamins and iron. Commonly returned controlled substance medications included narcotics such as hydrocodone/acetaminophen combinations and oxycodone, and sedative hypnotics such as zolpidem and lorazepam.

To evaluate the changes in types of medications prescribed for pain before and after withdrawal of certain selective cyclooxygenase 2 (COX-2) inhibitors in 2004 and to determine whether there was an association with fall events in elderly adults with a diagnosis of osteoarthritis (OA). A nested case-control design using electronic medical records compiled between 2001 and 2009. Electronic medical records for care provided in an integrated health system in rural Pennsylvania over a 9-year period (2001-09), the midpoint of which rofecoxib and valdecoxib were pulled from the market. Thirteen thousand three hundred fifty-four individuals aged 65 to 89 with a diagnosis of OA. The incidence of falls and fractures was examined in relation to analgesics prescribed: narcotics, COX-2 inhibitors, and nonsteroidal anti-inflammatory drugs (NSAIDs). The comparison sample of individuals who did not fall was matched 3:1 with those who fell according to age, sex, and comorbidity. Narcotic analgesic prescriptions were associated with a significantly greater risk of falls and fractures. The likelihood of experiencing a fall/fracture was higher in participants prescribed narcotic analgesics than those prescribed a COX-2 inhibitor (odds ratio (OR) = 3.3, 95% confidence interval (CI) = 2.5-4.3) or NSAID (OR = 4.1, 95% CI = 3.7-4.5). Use of narcotic analgesics is associated with risk of falls and fractures in elderly adults with OA, an observation that suggests that the current guidelines for the treatment of pain, which include first-line prescription of narcotics, should be reevaluated. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

Skin Permeation Enhancers and their Effects on Narcotic Transdermal Drug Delivery Systems through Response Surface Experimental Design

2014-02-01

Full Text Available Drug delivery through skin is often obstructed by low permeability of skin towards most drugs; however, such problem would be solved by application of skin penetration enhancers in the formulations. In the present study, a drug in adhesive patch with buprenorphine as active ingredient was prepared. Drug-in-adhesive transdermal drug delivery systems with different chemical penetration enhancers were designed. For this purpose a response-surface experimental design was used. Response surface methodology based on a three-level, three-variable Box–Behnken design was used to evaluate the interactive effects of dependent variables such as: the rate of skin permeation and adhesion properties including peel strength and tack value. The parameters such as drug release and adhesion were used as independent variables. Levulinic acid, lauryl alcohol and Tween 80 were used as penetration enhancers. In order to prepare samples, buprenorphine with constant concentration was incorporated into acrylic pressure sensitive adhesive with carboxylic functionality and this mixture was added to chemical penetration enhancer with different concentrations. The results show that the cumulative amount of drug release in presence of Tween 80 is 462.9 ± 0.006 μg so it is higher than cumulative amount of drug release in presence of levulinic acid (357.9 ± 0.005 μg and lauryl alcohol (269.5 ± 0.001 μg. Results of adhesion properties such as peel strength and tack reveal that using levulinic acid and lauryl alcohol will increase peel strength while Tween 80 will decrease it. Besides, the results show that all these permeation enhancers have increased tack values.

This report describes the collaboration between the South Texas Specialized Crimes and Narcotics Task Force (STSCNTF) and Sandia National Laboratories (SNL) in a field test that provided prototype hand-held trace detection technology for use in counter-drug operations. The National Institute of Justice (NIJ)/National Law Enforcement and Corrections Technology Center (NLECTC)/Border Research and Technology Center (BRTC) was contacted by STSCNTF for assistance in obtaining cutting-edge technology. The BRTC created a pilot project for Sandia National Laboratories (SNL) and the STSCNTF for the use of SNL’s Hound, a hand-held sample collection and preconcentration system that, when combined with a commercial chemical detector, can be used for the trace detection of illicit drugs and explosives. The STSCNTF operates in an area of high narcotics trafficking where methods of concealment make the detection of narcotics challenging. Sandia National Laboratories’ (SNL) Contraband Detection Department personnel provided the Hound system hardware and operational training. The Hound system combines the GE VaporTracer2, a hand-held commercial chemical detector, with an SNL-developed sample collection and preconcentration system. The South Texas Task force reported a variety of successes, including identification of a major shipment of methamphetamines, the discovery of hidden compartments in vehicles that contained illegal drugs and currency used in drug deals, and the identification of a suspect in a nightclub shooting. The main advantage of the hand-held trace detection unit is its ability to quickly identify the type of chemical (drugs or explosives) without a long lag time for laboratory analysis, which is the most common analysis method for current law enforcement procedures.

Closed to reason: time for accountability for the International Narcotic Control Board

2007-05-01

Full Text Available Abstract For more than two decades, the International Narcotic Control Board (INCB has tried to stop harm reduction and its HIV prevention programs. This posture is based on a fundamental misunderstanding of their responsibilities and of drug addiction itself – i.e. as a public health and clinical care matter made criminal by decree. A recent focal point for the Board's action has been rejecting the use of supervised injection facilities to reduce morbidity and mortality of drug injectors. They single out individual countries and attempt to bully them into rejecting such programs under the banner of the United Nations (falsely and in the name of international treaties. Their unrelenting and unjustified badgering of signatories to the international treaties that established the INCB is not only unjustified; it is an affront to one of the core purposes of the Board itself: to ensure adequate medical supplies and safe use of controlled substances. The INCB's ill-conceived obsession with intravenousaddiction as a crime flies in the face of the medical view and policies of the World Health Organization and the universally endorsed principles of the General Assembly of the United Nations. The latest target of the INCB is North America's only supervised injection facility, Insite, located in the inner city of Vancouver, Canada. Using the power of their office to meddle in matters of public health for individual nations is without medical, scientific or legal justification. But, most importantly, it is a matter of lifeand death for these most marginalized of citizens. The empirical evidence remains that a significant portion of the continued growth of the AIDS pandemic is due to injecting drug use, and the INCB's intrusion will inevitably result in additional deaths due to preventable HIV infections and drug overdoses. So we are very pleased to call to our readers' attention to a recent report produced by the Canadian HIV/AIDS Legal Network and the

2017-01-01

Full Text Available Background: The pattern of drug abuse in Iran has dramatically changed in recent years, turning from the traditional opioids [opium, opium dross, and refined opium dross (Shireh] into drugs with newer forms. The present study is aimed at investigating the frequency of pathological changes in the lungs of bodies with positive postmortem toxicology results for narcotics and psychotropic substances autopsied in the forensic dissection hall of Tehran, Iran [the Iranian Legal Medicine Organization (LMO]. Methods: The present study is a cross-sectional descriptive study. The sample consisted of 153 bodies, which had been referred to the LMO with positive results in postmortem toxicology for narcotics and psychotropic substances. Results: We found that narcotic drugs and psychotropic substances were used more in men than women. Moreover, the average age of death due to drug use was 36 years old. In addition, methamphetamine was the mostly-used type of substances, and smoking was the most widely used method to use the drugs. Besides, the dominant consistency and color of the lungs of half of the bodies investigated were elastic brown-gray. Moreover, the most common pathologic changes observed in the lungs of the bodies investigated were congestion and edema. Conclusion: Given the prevalence of pathological changes in the lungs of the examined bodies and congestion, edema, and pulmonary hemorrhage, the results of the present study can be particularly effective in determining the drug use and the resultant death in the absence of any previous records and/or a negative result of toxicology.

Full Text Available This article refers to the phenomenon of an increasing number of people abusing drugs in the 20th century. In addition to the natural types of narcotics there are many other semi-synthetic and fully synthetic substances made available to the market by chemical and pharmaceutical industries. The use of narcotics and psychoactive substances usually causes adverse and often irreversible health effects. In Department of Laboratory Diagnostics of the Institute of Occupational Medicine and Environmental Health in Sosnowiec tests for presence of drugs are among routinely conducted analyses. The presence of drugs has been revealed in 898 cases between the years 2004 and 2008. On top of the list of the most frequently detected narcotics were: amphetamine, cannabis, opiates, methamphetamine and cocaine. At the same time the most popular psychoactive substances are atropine, scopolamine and psilocybin. Additionally, the laboratory analyses indicated in many cases the presence of derivatives of benzodiazepines, trycyclic antidepressants and alcohol. Regional Centre of Acute Intoxication in Sosnowiec, Poland, hospitalized 78 patients due to overdose of drugs, narcotics or psychoactive substances as a result of experimenting with such substances. Half of the hospitalized cases patients have tried to commit suicide; one of the attempts has led to death. According to patients’ history their problems with reaching out for the use of psychoactive substances and narcotics were mainly caused by socio-psychological disorders.

Full Text Available The analysis of the data of the domestic and foreign literature regarding the dynamics of narcotization among children and adolescents is carried out. It has been established that at present the growth rates of the use of psychoactive substances by minors far outstrip those of the adult population. It is also determined that in most cases "adult" drug addiction is formed in a teenage environment and therefore adolescents are a group of high-risk narcotization. Besides, new types of additions are constantly added: non-opioid analgetics, antidepressants, pharmacy products based on medicinal plants with stimulating or sedative properties, new means of perfumery and household chemicals, volatile organic compounds, etc. In this regard, in the clinical picture of drug intoxication, new variations of affective, psycho-organic and psychosomatic effects and complications are noted. In recent years, synthetic cannabinoids has rapidly gained "popularity" among young people that are successfully promoted by marketers. They are the part of the so-called designer drugs, appearing in the markets in the form of bath salts, flavors, fertilizers for indoor plants and "smoking mixtures" - spices. The publications of domestic and foreign authors give a lot of evidence of the ability of these substances not only to cause a state of intoxication, alienation, relaxation, but also leads to dependence on them with severe consequences for the psyche and all organism as a whole. Thus, the powerful anthropogenic damaging effect of designer drugs demonstrates concrete signals of a threat to health, demography and the economy of the society as a result of their use by the population.

Full Text Available It is not unusual that narcotics-dependent patients fulfill their medical requirements in the emergency department (ED. The behavior of these patients varies, and their manifestations and predictors are still not fully studied. We performed this retrospective study by prospectively collecting data on patients with suspected drug dependence who were undiagnosed at first and then treated for some kind of reported pain at the ED. Patients who were confirmed to have narcotics dependence were compared with control patients in a ratio of 1:3 matching for age, gender, disease, and clinical diagnoses. From January 2006 to October 2009, 26 of 223 patients treated for pain were found to be drug dependent (12 males and 14 females. The average dose of narcotics used was higher than the control group [3.23 ± 1.14 vs. 1.12 ± 0.36, p < 0.001, confidence interval (CI: 1.648–2.583]. Numbers of patients making unscheduled returns to the ED within 24 hours were significant [24/26 vs. 8/78, p ≤ 0.001, odds ratio (OR 105.00, 95% CI 20.834–529.175]. In addition, patients showing aggressive attitudes were significant (17/26 vs. 2/78, p < 0.001, OR 71.78, 95% CI 14.206–362.663. In the case group, six of them told the physician that they were allergic to medicines other than the particular one they wanted, and three of the six presented injuries that were reported to be in the same (or repeated place for unscheduled returns, which were not found in the control group. In this study, some behaviors were commonly observed in the at-risk group. These patients were prone to manifest some types of symptoms and behaviors, such as uncontrolled pain with three doses of analgesics, aggressive attitude, returning to the ED within 24 hours with the complaint of the same severe pain, repeating the same injury, claiming allergy to other analgesics, and asking for certain analgesics. All these behaviors should alert the physician to suspect a drug-seeking problem.

It has been over half a century since the landmark Single Convention on Narcotic Drugs was adopted, for the first time unifying international drug policy under a single treaty aimed at limiting use, manufacture, trade, possession, and trafficking of opiates, cannabis, and other narcotics. Since then, other international drug policy measures have been adopted, largely emphasizing enforcement-based approaches to reducing drug supply and use. Recently, in response to concerns that the historic focus on criminalization and enforcement has had limited effectiveness, international drug policies have begun to undergo a paradigm shift as countries seek to enact their own reforms to partially depenalize or deregulate personal drug use and possession. This includes Mexico, which in 2009 enacted national drug policy reform partially decriminalizing possession of small quantities of narcotics for personal consumption while also requiring drug treatment for repeat offenders. As countries move forward with their own reform models, critical assessment of their legal compatibility and effectiveness is necessary. In this commentary we conduct a critical assessment of the compatibility of Mexico's reform policy to the international drug policy regime and describe its role in the current evolving drug policy environment. We argue that Mexico's reform is consistent with flexibilities allowed under international drug treaty instruments and related commentaries. We also advocate that drug policy reforms and future governance efforts should be based on empirical evidence, emphasize harm reduction practices, and integrate evidence-based evaluation and implementation of drug reform measures.

The first step for identification of medicinal plants and their therapeutic effects is to determine their use by local people, traditional medicine books and personal experiences. The aim of this study was to document the medicinal plants used as analgesic, sedative or narcotic agents by local residents of Dehloran, Iran. Interviews conducted with 53 informants (38 male and 15 female) revealed that a total of 32 medicinal plants belonging to 22 families are used in Dehloran as narcotic, sedative and analgesic agents. The most utilized plant families were Asteraceae, Rosaceae and Fabaceae. Approximately 74% of the utilized plants was attributed to herbs, followed by trees (13%) and shrubs (13%). Sixty-six percent of the medicinal plants used in the study area were perennial and the rest were annual or biannual. The most widely used plant parts were flowers (34%) followed by leaves (24%) and fruits (14%). Thirty-nine percent of the medicinal plants were used as sedatives, 39% as analgesics, and 24% as narcotics. Recommended plants in this study can be good candidates for further clinical and laboratory trials on diseases that are associated with pain, suffering, stress and depression. They also can be used to develop new sedative, narcotic and analgesic drugs.

Assessment of the Impact of the Narcotics Market on the Regional Socio-Economic Development

Aleksey Nikolaevich Klevakin

2018-03-01

Full Text Available The article considers the market of narcotics as a part of the formal and informal economy. By narcotics, the author means psychoactive substances and plants containing them, which are banned, subject to control or non-prohibited, but have a psychophysical effect on human body. Drug-related psychoactive substances are classified according to the prohibition criterion and restrictions on a turnover with reference to the illegal (criminal or shadow economy. The author considers the illegal drug market as a latent self-organizing system of socio-economic relations of criminal and shadow nature. Such market is oriented towards the turnover of potentially illegal or dangerous psychoactive substances, which are prohibited or restricted for use in non-medical purposes. The analysis of the state and development of the drug situation on the territory of the entities of the Ural Federal District confirms the relevance of the problem of drug abuse. In recent years, the primary incidence of drug addiction and harmful drug use among the adolescents aged 15–17 have grown. Synthetic narcotics and psychotropic substances of high narcogenicity dominate in the current drug market. Over the past 5 years, the average cost of a single dose of drug remains virtually unchanged. This reflects the conditional balance of purchasing power and competition in the drug market. The disparity in the volume of seized cannabis drugs and the number of cannabinoid users observed by medical institutions suggests a high level of latency in this category of drug users. To assess the degree of negative impact of the drug market, the author proposes to use a method of calculating the socioeconomic costs of the consequences of drug addiction. The methodology is supplemented with tools for determining the number of psychoactive substances consumers on the basis of the mass of these substances withdrawn from illicit trafficking, using the concentration and recalculation coefficients

Comparison between narcotic 'receptors' in the guinea-pig ileum and the rat brain

Energy Technology Data Exchange (ETDEWEB)

Terenius, L [Uppsala Univ. (Sweden)

1975-01-01

The receptors, i.e., specific binding molecules, for narcotic analgesics in the guinea-pig ileum and rat brain have been compared. The relative affinities of a number of narcotics for the two receptors were very similar and discrimination between stereoisomeric agents was identical. The dissociation constants for dihydromorphine binding were 0.78 nM for the ileum and 1.4 nM for the brain receptor, respectively. There was a good correspondance between receptor affinities on the ileum preparation and the literature data on biologic activity on the isolated ileum. Codeine, diphenoxylate, difenoxine and loperamide, which are used clinically for the treatment of diarrhoea showed no selectivity against the ileum receptor. The two latter drugs had a very high receptor affinity and their lack of narcotic activity after oral administration is probably attributable to lack of penetration of the CNS. Receptor binding in both ileum and brain preparations was inhibited by N-ethylmaleimide, Triton X-100, trypsin and phospholipase C. There were small quantitative differences in sensitivity to these agents but it is difficult to assess whether this is because of real differences between the receptor molecules or attributable to secondary effects. As previously described for the brain receptor, the ileum receptor appeared to be present in a fraction enriched in plasma membranes.

The concept and tasks of the basic method of investigation of crimes related to illegal trafficking narcotic drugs

Directory of Open Access Journals (Sweden)

Chistova L.E.

2017-04-01

Full Text Available the article substantiates the need to develop a basic methodology for investigating crimes related to illicit trafficking in narcotic drugs due to the fact that these crimes are inextricably linked, interdependent and can not be carried out separately from each other in principle. The existing separate private methods develop recommendations for the investigation of specific types of crimes, for example, only smuggling of these funds or their sale and they are not connected with each other. In this regard, it is not possible to trace the whole cycle of criminal activity from the introduction of controlled means to illicit trafficking prior to their sale. Therefore, the basic methodology for investigating such crimes will allow us to trace the whole chain of criminal acts and to reveal all the circumstances that affect the full and objective investigation of such crimes.

2017-08-01

Although drug use is considered a risk factor for child maltreatment, very little work has examined how the drug environment may affect physical abuse and neglect by parents. Utilizing information from a telephone survey with 2,597 respondents from 43 cities with valid police data on narcotics incidents, we analyzed the relationship between drug use, drug availability, and child maltreatment using multilevel models. City-level rates of drug abuse and dependence were related to more frequent physical abuse. Parents who use drugs in areas with greater availability of drugs reported more physical abuse and physical neglect. Emotional support was protective of all types of maltreatment. While most child welfare interventions focus on reducing parental drug use in order to reduce child abuse, these findings suggest environmental prevention or neighborhood strengthening approaches designed to reduce the supply of illicit drugs may also reduce child abuse through multiple mechanisms.

This paper investigates the discourses and policies on narcotics in Republic of Korea from 1945 to 1960. Since the Liberation the narcotic problem was regarded as the vestige of Japanese imperialism. which was expected to be cleaned up. The image of narcotic crimes as the legacy of the colonial past was turned into as the result of the Red Army's tactics to attack on the liberalist camp around the Korean war. The government of ROK represented the source of the illegal drugs as the Red army and the spy from North Korea. The anticommunist discourse about narcotics described the spies, who introduced the enormous amount of poppies into ROK and brought about the addicts, as the social evil. Through this discourse on poppies from North Korea, the government of ROK emphasized the immorality of the communists reinforcing the anticommunist regime, which was inevitable for the government of ROK to legitimize the division of Korea and the establishment of the government alone. This paper examines how the discourses and policies on narcotics in ROK was shaped and transformed from 1945 to 1960 focusing the relationship between the them and the political context such as anticommunism, Korean war, the division of Korea, and etc. This approach would be helpful to reveal the effect of the ROK's own political situation to the public health system involving the management for drugs.

Full Text Available Abstract Drug abuse has grown over the days with significant development. Narcotics crime actually not only brings individual actors but tends to be a criminal offense syndicate or covert organization over the worlds. In this case the syndicate allegedly not only brings perpetrators of adults but feared the actors who are categorized as a child in accordance with the applicable laws. On the other side children occupy a special place in the law. Basic philosophy of the treatment of juvenile delinquents is for the best interests of the child but the fact that peoples behavior lately is very alarming how society is so easy to judge people suspected as perpetrators of criminal acts. The objective of this research is to understand the essence of the ultimum remedium principle as the basis for criminal punishment in the Indonesian criminal system in order to understand how the crisis is influencing drug phenomenon and drugs users lives and the extent of their impact on the settlement of narcotics crime against children as an offender. The outcomes of the research indicate that the Law No. 11 of 2012 regarding the Criminal Justice System for Juvenile Delinquency Rules of the Supreme Court of the Republic of Indonesia No. 4 of 2014 on Guidelines for Diversion and Law No. 35 of 2009 regarding Narcotics Crime have been given the freedom and legitimacy to the judge to apply the principle of ultimum remedium in handling cases of children in conflict with the law. As it turns out in practice however the ultimum remedium principle is rarely applied and tends to be overlooked in the process of juvenile justice.

The narcotic clinic in New Orleans, 1919-21.

This paper traces the history of the narcotic clinic in New Orleans, Louisiana, comparing its merits to a similar clinic in Shreveport. How do the clinics compare, and why did the Shreveport clinic operate for longer than its New Orleans counterpart? Qualitative analysis of contemporary medical journals and newspapers, as well as archival materials from the Narcotic Division. In addition, the records of Louisiana Governor John M. Parker, the papers of Dr Willis P. Butler in Shreveport, as well as the records of the Orleans Parish Medical Society have been utilized. The narcotic clinic in Shreveport benefited from strong local support, while the New Orleans clinic faced a more vocal opposition. In addition, the Shreveport clinic offered a broad array of services and was a pillar of the community; the New Orleans clinic was newly established and offered fewer services. It was especially the influx of out-of-state addicts that angered many New Orleanians, many of whom witnessed the addicts lined up in the French Quarter. The effectiveness of the narcotic clinics in Louisiana (1919-23) was influenced by local opinion. The New Orleans clinic faced a tougher political climate than its counterpart in Shreveport, and therefore proved less resilient in the face of federal opposition. © 2017 Society for the Study of Addiction.

Gastrointestinal tract as a vehicle for drug smuggling

Energy Technology Data Exchange (ETDEWEB)

Four cases of attempts to smuggle narcotics (marijuana, heroin, and cocaine) by swallowing a large number of drug-filled foreign bodies (condoms and capsules) and hiding them from customs authorities in the gastrointestinal canal during transit are described. This is compared with a psychiatric patient who swallowed 48 Vicks Inhalers. Drug smuggling by swallowing condoms or capsules containing narcotics is now a worldwide ethical-legal problem. It also is of therapeutic and prognostic importance as this may lead to such emergencies as mechanical obstruction, rupture of the drug-containing foreign bodies, and life-threatening intoxication of the carrier.

The aim of the study was to assess color perception in the Farnsworth-Munsell 100-Hue test in individuals addicted to narcotic substances, and to analyze the acquired color vision disorders, depending on the duration of addiction and abstinence. Ninety-five persons were qualified for the study. All the subjects were divided into 3 groups. Group I (drug addicts) comprised 45 individuals addicted to narcotic substances and nicotine. Group II (smokers) consisted of 30 individuals addicted only to nicotine, and group III (abstinents) included 20 individuals free of addictions. In all the study groups anamnesis, survey, standard ophthalmological examination and the Farnsworth-Munsell 100-Hue test were performed. In the Farnsworth-Munsell 100-Hue test the mean values of total error score (TES) for the purposes of the analysis, expressed in the values of square root (√TES), proved to be significantly higher in group I than in the two other groups (p colors. The Farnsworth-Munsell 100-Hue test proved useful in the detection and assessment of acquired dyschromatopsy induced by narcotic substances. The observed disorders appeared to be dependent on the duration of addiction and abstinence. Med Pr 2016;67(6):777-785.

ADMINISTRATIVE AND ORGANIZATIONAL ASPECTS OF FUNCTIONING OF THE SYSTEM OF AVAILABILITY NARCOTIC AND PSYCHOTROPIC MEDICINAL PREPARATIONS FOR PATIENTS WHO NEED THEM

Directory of Open Access Journals (Sweden)

I. A. Kaminskaya

2016-01-01

Full Text Available Narcotic drugs and psychotropic substances still remain indispensable in medicine. One of the top priorities of health care is to ensure the required availability of this group of drugs. The development of an effective system which can ensure crucially important availability of narcotic and psychotropic agents to people who need them for medical purposes must rely on the identification and analysis of the nature and specificity of the problems related to them as well as the ways of solving these problems. ThePurpose of the Study was to explore the constituents of the system ensuring medicinal availability of narcotic and psychotropic agents and to identify the factors hindering the availability of this group of medicinal agents.Materials and Methods. The study involved the systematic review analysis of the scientific publications and guidance  documents regulating various aspects of activities involving the turnover of controlled drugs, and the results of surveys and interviews in which medical and pharmaceutical professionals were engaged. The study employed the methods of content analysis, logical and functional analysis, etc.Results and Discussion. The system of narcotic and psychotropic drug (NPD availability for patients who need them is currently going through reforms which have been conditioned by low accessibilty of these drugs when used for medical purposes. Those engaged in the drug supply system including medical and pharmaceutical professionals point out that excessive bureaucratization of the system of NPD supply and availability, complexity of documentation and paperwork reporting thedrug flow, costliness of these activities, and strict liability account for low availability of such drugs. To ensure the rights of the citizens to relieve pain due to diseases or medical interventions, a number of changes in the laws and regulations have been made. They have simplified the requirements for NPD

1988-01-01

The study involved 152 adolescents which had abused narcotic and toxic substances once, occasionally or regularly. Males aged 15 to 16 years displayed highest occurrence rate of the abuse. Drug addiction and toxicomania were established in 6% of subjects. Volatile stuff and tranquilizers were most frequent in use. Microsocial adversities were experienced by all the subjects. Besides, an "altered background" is characteristic of drug addicts and toxicomania patients. The fact of narcotic and toxic substances usage as euphorigenic agents deserves due attention of narcologists, pedagogues, sociologists. Biologically conditioned risk factors conducive to drug addiction and toxicomania should be investigated.

Efforts of Controlling Money Laundering of Narcotics Money in Saudi Arabia

Full Text Available Money laundering is a silent crime. Its goal is to cover up the source of large sums of money that criminals often gather from their criminal activities. This paper will analyze the situation of money laundering in narcotics as it applies in Saudi Arabia. To achieve this end, the paper will first define important terms such as money laundering and narcotics. It will then explain the relationship between money laundering, narcotics trade, and terrorism activities. This background information will form the base for analyzing the various efforts that the Saudi Arabia nation has in place for countering money laundering in narcotics trade. The paper will then explain the challenges facing these efforts, and the future of money laundering in Saudi Arabia. The largest criminal activity associated with money laundering is terrorism financing. The several terror attacks associated with Saudi Arabia’s terror groups like Al-Qaida have made the government realize the importance of curbing money laundering in an effort to counter terrorism. Thus, anti-money laundering strategies are set in place to address all the avenues of money laundering.

Applications of Monte Carlo technique in the detection of explosives, narcotics and fissile material using neutron sources

2009-01-01

The problem of illicit trafficking of explosives, narcotics or fissile materials represents a real challenge to civil security. Neutron based detection systems are being actively explored worldwide as a confirmatory tool for applications in the detection of explosives either hidden inside a vehicle or a cargo container or buried inside soil. The development of a system and its experimental testing is a tedious process and to develop such a system each experimental condition needs to be theoretically simulated. Monte Carlo based methods are used to find an optimized design for such detection system. In order to design such systems, it is necessary to optimize source and detector system for each specific application. The present paper deals with such optimization studies using Monte Carlo technique for tagged neutron based system for explosives and narcotics detection hidden in a cargo and landmine detection using backscatter neutrons. We will also discuss some simulation studies on detection of fissile material and photo-neutron source design for applications on cargo scanning. (author)

The insults of illicit drug use on male fertility.

Science.gov (United States)

Fronczak, Carolyn M; Kim, Edward D; Barqawi, Al B

2012-01-01

One-third of infertile couples may have a male factor present. Illicit drug use can be an important cause of male factor infertility and includes use of anabolic-androgenic steroids, marijuana, opioid narcotics, cocaine, and methamphetamines. The use of these illicit drugs is common in the United States, with a yearly prevalence rate for any drug consistently higher in males compared with females. We aim to provide a review of recent literature on the prevalence and effects of illicit drug use on male fertility and to aid health professionals when counseling infertile men whose social history suggests illicit drug use. Anabolic-androgenic steroids, marijuana, cocaine, methamphetamines, and opioid narcotics all negatively impact male fertility, and adverse effects have been reported on the hypothalamic-pituitary-testicular axis, sperm function, and testicular structure. The use of illicit drugs is prevalent in our society and likely adversely impacting the fertility of men who abuse drugs.

We sought to determine perioperative patterns of narcotic use and the prevalence of postoperative doctor shopping among patients with nephrolithiasis requiring operative management. We retrospectively reviewed the records of consecutive patients residing in Tennessee who required ureteroscopy with laser lithotripsy for nephrolithiasis at a single institution from January to December 2013. Using the Tennessee CSMD (Controlled Substances Medication Database) patients were categorized by the number of postoperative narcotic providers. Doctor shopping behavior was identified as any patient seeking more than 1 narcotic provider within 3 months of surgery. Demographic and clinical characteristics associated with doctor shopping behavior were identified. During the study period 200 eligible patients underwent ureteroscopy with laser lithotripsy for nephrolithiasis, of whom 48 (24%) were prescribed narcotics by more than 1 provider after surgery. Compared to those receiving narcotics from a single provider, patients with multiple narcotic providers were younger (48.1 vs 54.2 years, p shopping is common among patients with nephrolithiasis who require operative management. Urologists should be aware of available registry data to decrease the likelihood of redundant narcotic prescribing. Copyright © 2016 American Urological Association Education and Research, Inc.

Due to the time and effort requirements for the development of a new drug, and the high attrition rates associated with this developmental process, there is an intense effort by academic and industrial researchers to find novel ways for more effective drug development schemes. The first step in the discovery process of a new drug is the identification of the lead compound. The modern research tendency is to avoid the synthesis of new molecules based on chemical intuition, which is time and cost consuming, and instead to apply in silico rational drug design. This approach reduces the consumables and human personnel involved in the initial steps of the drug design. In this review real examples from our research activity aiming to discover new leads will be given for various dire warnings diseases. There is no recipe to follow for discovering new leads. The strategy to be followed depends on the knowledge of the studied system and the experience of the researchers. The described examples constitute successful and unsuccessful efforts and reflect the reality which medicinal chemists have to face in drug design and development. The drug stability is also discussed in both organic molecules and metallotherapeutics. This is an important issue in drug discovery as drug metabolism in the body can lead to various toxic and undesired molecules.

Peptidase inhibitors reduce opiate narcotic withdrawal signs, including seizure activity, in the rat.

Science.gov (United States)

Pinsky, C; Dua, A K; LaBella, F S

1982-07-15

Narcotic withdrawal was precipitated by administration of naloxone in a low dose at 2 h after the final dose of morphine in a 9-day dependency-inducing schedule. Withdrawal was characterized by leaps, increased nocifensor activity and by cerebral cortical epileptiform activity, the latter not generally reported to be prominent in narcotic withdrawal. Single large doses of morphine did not provoke epileptiform activity at 2 h postinjection but did induce an acute opioid dependency wherein a moderately high dose of naloxone, ineffective in non-dependent rats, provoked upward leaping and electrocortical epileptiform activity. Pretreatment of the 9-day dependent rats with peptidase inhibitors, administered intracerebroventricularly, significantly reduced withdrawal severity including the epileptiform activity. We propose that peptidase inhibitors protect certain species of endogenous opioids and/or other neuropeptides that tend to suppress expression of the narcotic withdrawal syndrome. Furthermore, our findings suggest that epileptiform activity is a nascent form of cerebral activity hitherto largely unnoticed in narcotic withdrawal and that neuropeptides may be involved in certain epileptic states.

Validated data regarding HIV-transmission in prisons in developing countries is scarce. We examined sexual and injecting drug use behavior and HIV and HCV transmission in an Indonesian narcotic prison during the implementation of an HIV prevention and treatment program during 2004-2007 when the Banceuy Narcotic Prison in Indonesia conducted an HIV transmission prevention program to provide 1) HIV education, 2) voluntary HIV testing and counseling, 3) condom supply, 4) prevention of rape and sexual violence, 5) antiretroviral treatment for HIV-positive prisoners and 6) methadone maintenance treatment. During a first survey that was conducted between 2007 and 2009, new prisoners entered Banceuy Narcotics Prison were voluntary tested for HIV and HCV-infection after written informed consent was obtained. Information regarding sexual and injecting risk behavior and physical status were also recorded at admission to the prison. Participants who tested negative for both HIV and HCV during the first survey were included in a second survey conducted during 2008-2011. During both surveys, data on mortality among HIV-seropositive patients were also recorded. All HIV-seropositive participants receive treatment for HIV. HIV/ AIDS-related deaths decreased: 43% in 2006, 18% in 2007, 9% in 2008 and 0% in 2009. No HIV and HCV seroconversion inside Banceuy Narcotic Prison were found after a median of 23 months imprisonment (maximum follow-up: 38 months). Total of 484.8 person-years observation was done. Participants reported HIV transmission risk-behavior in Banceuy Prison during the second survey was low. After implementation of HIV prevention and treatment program, no new HIV or HCV cases were detected and HIV-related mortality decreased.

[The issue of harm reduction in Polish legislation concerning drug addiction. A comparative study].

Science.gov (United States)

Sobeyko, Justyna

2008-01-01

The aim of work is the assessment of legal permissibility for health and social harm reduction programmes resulting from drug use in the context of the polish legislation on narcotic drug use and drug addiction. The thesis outlines harm reduction programmes implemented worldwide, role of penal code in counteracting both narcotic drug supply and demand, attitude of United Nations and European Union to the drug problem including harm reduction programmes, solutions adopted in the selected European Union member states. The main part of the thesis presents the evolution of polish legislation regarding drug use and analysis of legal permissibility for harm reduction programmes in this context. The conclusion inferred is the statement that implementation of the harm reduction programmes requires a certain minimal depenalisation of the drug use by a legislator and the fact that restrictive legal system impedes programme realization. Thus the thesis postulates depenalisation of small drug quantities for personal use.

Comparison of results for morphine urinalyses by radioimmunoassay and thin-layer chromatography in a narcotic clinic setting.

Science.gov (United States)

Kokoski, R J; Jain, M

1975-03-01

Radioimmunoassay (RIA) and thin-layer chromatography (TLC) were compared for morphine detection in an actual narcotic clinic setting. A choice of urines from all those screened by TLC allowed a critical comparison as to actual use or non-use of narcotic drugs, rather than a sampling at random in which the question of possible false positives or negatives cannot be conclusively answered. Although RIA is more sensitive than TLC, its advantage is apparent only in those cases where urine specimens are difficult to obtain frequently regularly or where the use of morphine is suspected by the positive identification of quinine in urine that was morphine-negative by TLC. In a selected group of negative and positive specimens chosen without conscious bias, the two methods gave consistently similar results, indicating that the modified TLC method provided a few or no false positives or negatives if the negatives were from those cases that were not positive anytime up to 3-4 days before urine collection. We conclude that RIA can be of significant value as a supplement to a TLC screening program, without sacrificing the many advantages that TLC has to offer.

Full Text Available The objective of this work was design, characterization, and optimization of controlled drug delivery system containing antibiotic drug/s. Osmotic drug delivery system was chosen as controlled drug delivery system. The porous osmotic pump tablets were designed using Plackett-Burman and Box-Behnken factorial design to find out the best formulation. For screening of three categories of polymers, six independent variables were chosen for Plackett-Burman design. Osmotic agent sodium chloride and microcrystalline cellulose, pore forming agent sodium lauryl sulphate and sucrose, and coating agent ethyl cellulose and cellulose acetate were chosen as independent variables. Optimization of osmotic tablets was done by Box-Behnken design by selecting three independent variables. Osmotic agent sodium chloride, pore forming agent sodium lauryl sulphate, and coating agent cellulose acetate were chosen as independent variables. The result of Plackett-Burman and Box-Behnken design and ANOVA studies revealed that osmotic agent and pore former had significant effect on the drug release up to 12 hr. The observed independent variables were found to be very close to predicted values of most satisfactory formulation which demonstrates the feasibility of the optimization procedure in successful development of porous osmotic pump tablets containing antibiotic drug/s by using sodium chloride, sodium lauryl sulphate, and cellulose acetate as key excipients.

Medicare Advantage prescription drug plans (MA-PDs) and standalone prescription drug plans (PDPs) face different incentives for plan design resulting from the scope of covered benefits (only outpatient drugs for PDPs versus all drug and nondrug services for Medicare Advantage [MA]/MA-PDs). The objective is to begin to explore how MA-PDs and PDPs may be responding to their different incentives related to benefit design. We compared 2012 PDP and MA-PD average formulary coverage, prior authorization (PA) or step therapy use, and copayment requirements for drugs in 6 classes used commonly among Medicare beneficiaries. We primarily used 2012 Prescription Drug Plan Formulary and Pharmacy Network Files and MA enrollment data. 2011 Truven Health MarketScan claims were used to estimate drug prices and to compute drug market share. Average coverage and PA/step rates, and average copayment requirements, were weighted by plan enrollment and drug market share. MA-PDs are generally more likely to cover and less likely to require PA/step for brand name drugs with generic alternatives than PDPs, and MA-PDs often have lower copayment requirements for these drugs. For brands without generics, we generally found no differences in average rates of coverage or PA/step, but MA-PDs were more likely to cover all brands without generics in a class. We found modest, confirmatory evidence suggesting that PDPs and MA-PDs respond to different incentives for plan design. Future research is needed to understand the factors that influence Medicare drug plan design decisions.

The War on “Red Drugs”: Anticommunism and Drug Policy in Republic of Korea, 1945-1960

Ji-Young Park

2016-04-01

Full Text Available This paper investigates the discourses and policies on narcotics in Republic of Korea from 1945 to 1960. Since the Liberation the narcotic problem was regarded as the vestige of Japanese imperialism. which was expected to be cleaned up. The image of narcotic crimes as the legacy of the colonial past was turned into as the result of the Red Army’s tactics to attack on the liberalist camp around the Korean war. The government of ROK represented the source of the illegal drugs as the Red army and the spy from North Korea. The anticommunist discourse about narcotics described the spies, who introduced the enormous amount of poppies into ROK and brought about the addicts, as the social evil. Through this discourse on poppies from North Korea, the government of ROK emphasized the immorality of the communists reinforcing the anticommunist regime, which was inevitable for the government of ROK to legitimize the division of Korea and the establishment of the government alone. This paper examines how the discourses and policies on narcotics in ROK was shaped and transformed from 1945 to 1960 focusing the relationship between the them and the political context such as anticommunism, Korean war, the division of Korea, and etc. This approach would be helpful to reveal the effect of the ROK’s own political situation to the public health system involving the management for drugs.

The purpose of this study is to estimate the risk of nonfatal acute myocardial infarction (AMI) associated with traditional NSAIDs (tNSAIDs), non-narcotic analgesics (paracetamol and metamizole), and symptomatic slow-acting drugs in osteoarthritis (SYSADOAs) overall and in different subgroups of patients. We performed a nested case-control study using a Primary Care Database (Base de datos para la Investigación Farmacoepidemiológica en Atención Primaria), over the study period, 2001-2007. We included patients aged 40-90 years, with nonfatal AMI and randomly selected controls matched for age, sex and calendar year. Exposure to drugs was assessed within a 30-day window before the index date. We did not find an association with nonfatal AMI in patients at low-intermediate background cardiovascular risk (odds ratio = 0.92; 95% confidence interval: 0.76-1.12), whereas there was a moderate significant association among those at high risk (1.28; 1.06-1.54) or when tNSAIDs were used for longer than 365 days (1.43; 1.12-1.82). The greatest risk occurred when these two conditions were combined (1.80; 1.26-2.58). The risk varied across individual tNSAIDs, with ibuprofen (0.95; 0.78-1.16) in the lower and aceclofenac (1.59; 1.15-2.19) in the upper part of the range. Low-dose aspirin did not modify the risk profile showed by any of the individual tNSAIDs examined. Paracetamol (0.84; 0.74-0.95), metamizole (1.06; 0.87-1.29) and SYSADOAs (0.68; 0.47-0.99) were not associated with an increased risk overall or in any subgroup of patients. The risk of nonfatal AMI varied with individual tNSAIDs, duration of treatment and background cardiovascular risk. Paracetamol, metamizole and SYSADOAs did not increase the risk in any of the conditions examined. Copyright © 2014 John Wiley & Sons, Ltd.

Continued development of a portable widefield hyperspectral imaging (HSI) sensor for standoff detection of explosive, chemical, and narcotic residues

Passive, standoff detection of chemical, explosive and narcotic threats employing widefield, shortwave infrared (SWIR) hyperspectral imaging (HSI) continues to gain acceptance in defense and security fields. A robust and user-friendly portable platform with such capabilities increases the effectiveness of locating and identifying threats while reducing risks to personnel. In 2013 ChemImage Sensor Systems (CISS) introduced Aperio, a handheld sensor, using real-time SWIR HSI for wide area surveillance and standoff detection of explosives, chemical threats, and narcotics. That SWIR HSI system employed a liquid-crystal tunable filter for real-time automated detection and display of threats. In these proceedings, we report on a next generation device called VeroVision™, which incorporates an improved optical design that enhances detection performance at greater standoff distances with increased sensitivity and detection speed. A tripod mounted sensor head unit (SHU) with an optional motorized pan-tilt unit (PTU) is available for precision pointing and sensor stabilization. This option supports longer standoff range applications which are often seen at checkpoint vehicle inspection where speed and precision is necessary. Basic software has been extended to include advanced algorithms providing multi-target display functionality, automatic threshold determination, and an automated detection recipe capability for expanding the library as new threats emerge. In these proceedings, we report on the improvements associated with the next generation portable widefield SWIR HSI sensor, VeroVision™. Test data collected during development are presented in this report which supports the targeted applications for use of VeroVision™ for screening residue and bulk levels of explosive and drugs on vehicles and personnel at checkpoints as well as various applications for other secure areas. Additionally, we highlight a forensic application of the technology for assisting forensic

Detection of Stimulants and Narcotics by Liquid Chromatography-Tandem Mass Spectrometry and Gas Chromatography-Mass Spectrometry for Sports Doping Control.

Ahrens, Brian D; Kucherova, Yulia; Butch, Anthony W

2016-01-01

Sports drug testing laboratories are required to detect several classes of compounds that are prohibited at all times, which include anabolic agents, peptide hormones, growth factors, beta-2 agonists, hormones and metabolic modulators, and diuretics/masking agents. Other classes of compounds such as stimulants, narcotics, cannabinoids, and glucocorticoids are also prohibited, but only when an athlete is in competition. A single class of compounds can contain a large number of prohibited substances and all of the compounds should be detected by the testing procedure. Since there are almost 70 stimulants on the prohibited list it can be a challenge to develop a single screening method that will optimally detect all the compounds. We describe a combined liquid chromatography-tandem mass spectrometry (LC-MS/MS) and gas chromatography-mass spectrometry (GC-MS) testing method for detection of all the stimulants and narcotics on the World Anti-Doping Agency prohibited list. Urine for LC-MS/MS testing does not require sample pretreatment and is a direct dilute and shoot method. Urine samples for the GC-MS method require a liquid-liquid extraction followed by derivatization with trifluoroacetic anhydride.

2011-01-01

The Russian Federation (RF) is committed to implementing a comprehensive drug testing program under its Personnel Reliability Program (PRP) for military personnel involved in handling sensitive nuclear materials. This commitment leads to a number of mandatory requirements for the laboratory conducting the confirmation testing to ensure the legitimacy and integrity of the testing process. These requirements are established by the RF Duma to ensure that individuals conducting these tests have adequate training, certifications, and experience to conduct narcotic confirmation tests. This paper describes the facility requirements and personnel qualifications needed for conducting comprehensive drug abuse confirmation testing. Details regarding the personnel training and laboratory experience in the theory and practice of analytical forensic toxicology of drugs of abuse will be presented, as well as the facility requirements for the laboratory conducting such tests. Chain-of-custody, from sample receipt through completion of testing, reporting of results, and continuing until final disposition of specimens will be addressed.

Metabolism of designer drugs of abuse.

Staack, Roland F; Maurer, Hans H

2005-06-01

Abuse of designer drugs is widespread among young people, especially in the so-called "dance club scene" or "rave scene", worldwide. Severe and even fatal poisonings have been attributed to the consumption of such drugs of abuse. However, in contrast to new medicaments, which are extensively studied in controlled clinical studies concerning metabolism, including cytochrome P450 isoenzyme differentiation, and further pharmacokinetics, designer drugs are consumed without any safety testing. This paper reviews the metabolism of new designer drugs of abuse that have emerged on the black market during the last years. Para-methoxyamphetamine (PMA), para-methoxymethamphetamine (PMMA) and 4-methylthioamphetamine (4-MTA), were taken into consideration as new "classical" amphetamine-derived designer drugs. Furthermore, N-benzylpiperazine (BZP), 1-(3, 4-methylenedioxybenzyl)piperazine (MDBP), 1-(3-trifluoromethylphenyl)piperazine (TFMPP), 1-(3-chlorophenyl)piperazine (mCPP) and 1-(4-methoxyphenyl)piperazine (MeOPP) were taken into consideration as derivatives of the class of piperazine-derived designer drugs, as well as alpha-pyr-rolidinopropiophenone (PPP), 4'-methoxy-alpha-pyrrolidinopropiophenone (MOPPP), 3', 4'-methylenedioxy-alpha-pyrrolidino-propiophenone (MDPPP), 4'-methyl-alpha-pyrrolidinopropiophenone (MPPP), and 4'-methyl-alpha-pyrrolidinoexanophenone (MPHP) as derivatives of the class of alpha-pyrrolidinophenone-derived designer drugs. Papers describing identification of in vivo or in vitro human or animal metabolites and cytochrome P450 isoenzyme dependent metabolism have been considered and summarized.

Over the last few decades, computer-aided drug design has emerged as a powerful technique playing a crucial role in the development of new drug molecules. Structure-based drug design and ligand-based drug design are two methods commonly used in computer-aided drug design. In this article, we discuss the theory behind both methods, as well as their successful applications and limitations. To accomplish this, we reviewed structure based and ligand based virtual screening processes. Molecular dynamics simulation, which has become one of the most influential tool for prediction of the conformation of small molecules and changes in their conformation within the biological target, has also been taken into account. Finally, we discuss the principles and concepts of molecular docking, pharmacophores and other methods used in computer-aided drug design.

Smarter Drugs: How Protein Crystallography Revolutionizes Drug Design

International Nuclear Information System (INIS)

Smith, Clyde

2005-01-01

According to Smith, protein crystallography allows scientists to design drugs in a much more efficient way than the standard methods traditionally used by large drug companies, which can cost close to a billion dollars and take 10 to 15 years. 'A lot of the work can be compressed down,' Smith said. Protein crystallography enables researchers to learn the structure of molecules involved in disease and health. Seeing the loops, folds and placement of atoms in anything from a virus to a healthy cell membrane gives important information about how these things work - and how to encourage, sidestep or stop their functions. Drug design can be much faster when the relationship between structure and function tells you what area of a molecule to target. Smith will use a timeline to illustrate the traditional methods of drug development and the new ways it can be done now. 'It is very exciting work. There have been some failures, but many successes too.' A new drug to combat the flu was developed in a year or so. Smith will tell us how. He will also highlight drugs developed to combat HIV, Tuberculosis, hypertension and Anthrax.

Bates, Cory; Laciak, Robert; Southwick, Andrew; Bishoff, Jay

2011-02-01

Prescription narcotic abuse is a significant social problem. Surplus medication following surgery is 1 source of prescription diversion. We assessed prescribing practices, consumption and disposal of prescribed narcotics after urological surgery. Surveys were administered to a 3-month consecutive sample of adult patients who underwent surgery performed by full and adjunct University of Utah Urology faculty. Surveys were performed 2 to 4 weeks postoperatively. With the exception of the investigators, prescribing physicians had no prior knowledge of the study. Data collected included perception of pain control, type and quantity of medication prescribed, quantity of leftover medication, refills needed, disposal instructions and surplus medication disposition. Overall 47% of 586 patients participated in the study. Hydrocodone was prescribed most commonly (63%), followed by oxycodone (35%), and 86% of the patients were satisfied with pain control. Of the dispensed narcotics 58% was consumed and 12% of patients requested refills. A total of 67% of patients had surplus medication from the initial prescription and 92% received no disposal instructions for surplus medication. Of those patients with leftover medication 91% kept the medication at home while 6% threw it in the trash, 2% flushed it down the toilet and less than 1% returned it to a pharmacy. Overprescription of narcotics is common and retained surplus medication presents a readily available source of opioid diversion. It appears that no entity on the prescribing or dispensing ends of prescription opioid delivery is fulfilling the responsibility to accurately educate patients on proper surplus medication disposal. Surgeons should analyze prescribing practices and consider decreasing the quantity of postoperative narcotics prescribed. Copyright © 2011 American Urological Association Education and Research, Inc.

Full Text Available Introduction: Higher education system in each country is mainly responsible for training specialists and efficient personnels in different levels of government. Regarding a community approach, if the system uses social factors properly, goals attainment will be facile. On the contrary, if the system is affected by common social traumas and deviations, it will result in dissonant maladroit graduated students who would trouble themselves, their family and their society. Addiction to narcotic drugs is one of the most important social traumas that is quite common in developing countries. Materials and Methods: The current descriptive analytic study has been conducted in community of Yazd University in academic year of 2010 -2011. For this purpose, 406 students of this university were selected via stratified random sampling method who responded to a researcher-made questionnaire that its validity and reliability were confirmed utilizing psychometric standards. Regarding data description, frequency indexes, percent, mean, and standard deviation were applied. Moreover, inferential tests of chi-square test and correlation coefficient of Pearson were utilized. Results: The study results revealed that approximately 21/9 percent of students were suggested the drug abuse whose rate of drug use was 25/9 percent. 34/1 percent of subjects determined their friend's homes as the most propitious place for their use and most important reasons involved respectively release of spiritual stress, inability to say "No" in response to others’ suggestion. Furthermore, students’ point of view revealed the significant effect of narcotic drugs use on education process. Any of students’ demographic variables had significant correlation with drug abuse. conclusion: since one of the most common social traumas associated with youth generation, specially college students, is addiction to narcotic drugs, that in addition to extensive economic loss, it would jeopardize their

Directory of Open Access Journals (Sweden)

M.H. Lotfi

2012-07-01

Full Text Available Introduction: Addiction is a habit or behavior that is often hard to quit. It is estimated that 190 million persons are substance users around the world. Substance abuse creates tolerance after a while. Shortly after taking the drug, a person will not enjoy as the beginning of its use; that is why the amount of substance used is gradually increased. The purpose of this study was to find the reasons of tendency to narcotics among addicted individuals referred to methadone maintenance therapy (MMT center in Yazd. Materials & Methods: This study was a descriptive-analytic study on 100 addicts referred to methadone maintenance treatment center (MMT in Yazd. Data was collected by a pre-designed questionnaire with acceptable validity and reliability. Data was analyzed using SPSS statistical software and employing descriptive statistics such as percentage, ratio, mean, standard deviation and statistical tests such as t-test and chi- square was performed. Results: 41.9 % of addicts were unemployed, 4.77% married and 5.64% had elementary education. The most common method of substance consumption was inhalation (2.40%. Heroin was the most frequent type of substance used (1/51% The relationship between marital status and type of substance used, and age of onset of drug use was significant. The frequency of substance consumption was significantly different regarding the history of drug use in father, brother and spouses of patients in both sexes. Conclusion: Results of the current study showed that subjects at an early age (adolescence and early adulthood, individuals with low educational status, those with unstable jobs and low income, presence of addicted individuals among first-degree relatives can be the causes leading to addiction in the community.

The aim of this investigation was to examine illegal tablets and capsules seized in Jutland, the western part of Denmark, during the period 1995-1999. The drugs are described according to technical appearance (colour, logo, score, diameter) and content of synthetic drugs. All illegal tablets and capsules received during the period 1995-1999 (109 cases containing 192 different samples) were examined. MDMA was the most common drug and was seen during the entire period. Amphetamine was the second most common drug and has been frequently detected during the the last two years. Drugs like MDE, MBDB, BDB, and 2-CB were rarely seen and they disappeared quickly from the illegal market. MDA appeared on the market at the end of 1999. Only 53% of the tablets contained MDMA as the sole drug. Eighty-one percent of the tablets/capsules contained only one synthetic drug, whereas 13% contained a mixture of two or more synthetic drugs. Six per cent of the samples did not contain a euphoric drug/designer drug. The content of MDMA, MDE, and amphetamine in the tablets varied greatly. MDMA is apparently the drug preferred by the users, but still only half of the tablets contained MDMA as the only drug. The rest of the tablets contained either another synthetic drug or a mixture of drugs. In conclusion, the increasing supply of various drugs with different and unpredictable effects and of miscellaneous quality brings about the risk of serious and complicated intoxications.

The article deals with the problems concerning aetiology and pathogenesis of damages to blood vessels in patients practicing parenteral administration of surrogates of narcotic substances. In order to clinically and experimentally study the pattern of morphological alterations in the area of narcotic substances administration and to work out an appropriate classification of the forms and stages of development of the pathological process, the authors analysed the clinical course of vascular lesions and complications thereof in a total of 244 drug abusers having parenterally administered surrogates of narcotic substances and undergoing treatment at the Department of Vascular Surgery of the Municipal Clinical Hospital of the city of Almaty. Additionally, experimental studies were carried out on 16 rabbits with the induced model of parenteral administration of surrogates of narcotic substances, thus making it possible to study the degree of their effect and to confirm the theory of a chemical impact of the homemade drugs on the vascular wall. The findings of the carried out studies enabled us to single out the following clinical stages of vascular lesions: stage I - the initial stage of cicatricial-and-ulcerous lesions formation, stage II - formation of cutaneous-and-vascular fistulas, stage III - the stage of complications characterized by development of health-hazardous vascular lesions, i. e., arterial and venous thromboses of the major vessels, as well as arrosive bleedings. It was noted that more than 50% of patients were admitted to the clinic presenting with the third stage of vascular lesions. The experimental part of the study included 64 experiments on 16 rabbits (one experiment per each paw of the animal). The laboratory animals were subdivided into three groups. The first experimental group consisted of the rabbits with a mechanically inflicted injury to the vessels. The second and third experimental groups were composed of the rabbits having received

Introduction A key part of drug design and development is the optimization of molecular interactions between an engineered drug candidate and its binding target. Thermodynamic characterization provides information about the balance of energetic forces driving binding interactions and is essential for understanding and optimizing molecular interactions. Areas covered This review discusses the information that can be obtained from thermodynamic measurements and how this can be applied to the drug development process. Current approaches for the measurement and optimization of thermodynamic parameters are presented, specifically higher throughput and calorimetric methods. Relevant literature for this review was identified in part by bibliographic searches for the period 2004 – 2011 using the Science Citation Index and PUBMED and the keywords listed below. Expert opinion The most effective drug design and development platform comes from an integrated process utilizing all available information from structural, thermodynamic and biological studies. Continuing evolution in our understanding of the energetic basis of molecular interactions and advances in thermodynamic methods for widespread application are essential to realize the goal of thermodynamically-driven drug design. Comprehensive thermodynamic evaluation is vital early in the drug development process to speed drug development towards an optimal energetic interaction profile while retaining good pharmacological properties. Practical thermodynamic approaches, such as enthalpic optimization, thermodynamic optimization plots and the enthalpic efficiency index, have now matured to provide proven utility in design process. Improved throughput in calorimetric methods remains essential for even greater integration of thermodynamics into drug design. PMID:22458502

This research has focused on the birthing experience of first-time mothers who received the narcotic analgesic combination of Pethidine and Hydroxyzine during the first stage of labour. A qualitative research methodology was used to collect data. Unstructured interviews were held with first-time mothers to obtain accounts of their experience of childbirth. These narrations were audio-taped while the participants were still being cared for in the postnatal ward of the hospital where delivery took place. Nine interviews were conducted with first-time mothers who gave birth normally vaginally after a normal pregnancy and who received a narcotic analgesic in the first stage of labour. The transcribed interviews were analyzed using Tesch's method of descriptive analysis (in Creswell, 1994:115). Four themes with sub-themes emerged from the analysis. The participants reported on the physical experience of labour and described experiencing a lot of pain for which analgesics were given. They also described how these drugs dulled the pain but made them sleepy and unable to cooperate with the midwives. They described their emotional experiences, which included joy and happiness as well as anxiety, anger and despondence. They also reported that they were not sufficiently informed about labour and child-birth. In the last theme they described the methods they used to help them cope with labour including distracting techniques, leaning on a supportive person or praying. Guidelines to help midwives overcome these problems were developed.

[Effects of the new comprehensive system for designating illegal drug components on the abuse of designer drugs and future problems based on an online questionnaire].

Morino, Taichi; Okazaki, Mitsuhiro; Toda, Takaki; Yokoyama, Takashi

2015-12-01

Recently, the abuse of designer drugs has become a social problem. Designer drugs are created by modifying part of the chemical structure of drugs that have already been categorized as illegal, thereby creating a different chemical compound in order to evade Pharmaceutical Affairs Law regulations. The new comprehensive system for designating illegal drug components has been in effect since March 2013, and many designer drugs can now be regulated. We conducted an online questionnaire survey of people with a history of designer drug use to elucidate the effects of the new system on the abuse of designer drugs and to identify potential future problems. Over half the subjects obtained designer drugs only before the new system was implemented. Awareness of the system was significantly lower among subjects who obtained designer drugs for the first time after its introduction than those who obtained the drugs only before its implementation. Due to the new system, all methods of acquiring designer drugs saw decreases in activity. However, the ratio of the acquisition of designer drugs via the Internet increased. Since over 50% of the subjects never obtained designer drugs after the new system was introduced, goals that aimed to make drug procurement more difficult were achieved. However, awareness of the new system among subjects who obtained designer drugs after the new system was introduced was significantly low. Therefore, fostering greater public awareness of the new system is necessary. The results of the questionnaire also suggested that acquiring designer drugs through the Internet has hardly been affected by the new system. We strongly hope that there will be a greater push to restrict the sale of designer drugs on the Internet in the near future.

Full Text Available A new phenomenon in the drug market has appeared in recent years: there has been an increase in the number and types of designer drugs. A massive influx of these structural and/or functional analogs of controlled substances has resulted in an increase in their marketing and abuse. At present, these drugs are significantly more widely available compared to previous years because they are relatively inexpensive and marketed as being safer than classic drugs of abuse. The most important factor in the spread of designer drugs is that the majority of these substances are undetectable as drugs or illegal drugs in standard drug testing procedures. The biological effects of these substances are largely unknown to both users and medical scientists. However, most known cases of abuse have shown serious and dangerous physical and psychological reactions in users. The manufacturing and marketing of designer drugs presents a major challenge for specialist sectors, especially laboratories that have to test these substances. This highlights the important role of drugcontrol institutions and regulatory and legislative bodies to determine the legal status of these drugs, which are designed and marketed - mostly through the internet - as being legal. All of these factors make it incumbent upon these sectors to form a unified goal and strategy to control these substances and prevent their spread. This review provides fundamental information about designer drugs. This will provide an accurate overview of their status, and will aid future work to develop a regulatory and legislative strategy to combat their manufacture, marketing, and use.

Marijuana-based drugs: innovative therapeutics or designer drugs of abuse?

Science.gov (United States)

Seely, Kathryn A; Prather, Paul L; James, Laura P; Moran, Jeffery H

2011-02-01

The principal psychoactive component of marijuana, Δ(9)-tetrahydrocannabinol (THC), activates CB1 cannabinoid receptors (CB1Rs). Unfortunately, pharmacological research into the design of effective THC analogs has been hampered by psychiatric side effects. THC-based drug design of a less academic nature, however, has led to the marketing of "synthetic marijuana," labeled as K2 or "Spice," among other terms, which elicits psychotropic actions via CB1R activation. Because of structural dissimilarity to THC, the active ingredients of K2/Spice preparations are widely unregulated. The K2/Spice "phenomenon" provides a context for considering whether marijuana-based drugs will truly provide innovative therapeutics or merely perpetuate drug abuse.

Return to Galileo? The Inquisition of the International Narcotic Control Board.

Science.gov (United States)

Small, Dan; Drucker, Ernest

2008-05-07

2010-01-01

Through a cooperative effort between the U. S. Department of Energy and the Russian Federation (RF) Ministry of Defense (MOD) a Personnel Reliability Program (PRP) for the nuclear handlers within the RF MOD has been implemented. A key element in the RF MOD PRP is the detection and confirmation of narcotic use in subject military and civilian personnel. This paper describes the process of narcotics screening and testing in the RF MOD and explains the confirmation process once screening has shown a positive result. Issues of laboratory certification, employee certification, employee training, sample chain-of-custody, and equipment needs will be addressed.

Computer based method can help in discovery of leads and can potentially eliminate chemical synthesis and screening of many irrelevant compounds, and in this way, it save time as well as cost. Molecular modeling systems are powerful tools for building, visualizing, analyzing and storing models of complex molecular structure that can help to interpretate structure activity relationship. The use of various techniques of molecular mechanics and dynamics and software in Computer aided drug design along with statistics analysis is powerful tool for the medicinal chemistry to synthesis therapeutic and effective drugs with minimum side effect.

Modeling chemical reactions for drug design.

Chemical reactions are involved at many stages of the drug design process. This starts with the analysis of biochemical pathways that are controlled by enzymes that might be downregulated in certain diseases. In the lead discovery and lead optimization process compounds have to be synthesized in order to test them for their biological activity. And finally, the metabolism of a drug has to be established. A better understanding of chemical reactions could strongly help in making the drug design process more efficient. We have developed methods for quantifying the concepts an organic chemist is using in rationalizing reaction mechanisms. These methods allow a comprehensive modeling of chemical reactivity and thus are applicable to a wide variety of chemical reactions, from gas phase reactions to biochemical pathways. They are empirical in nature and therefore allow the rapid processing of large sets of structures and reactions. We will show here how methods have been developed for the prediction of acidity values and of the regioselectivity in organic reactions, for designing the synthesis of organic molecules and of combinatorial libraries, and for furthering our understanding of enzyme-catalyzed reactions and of the metabolism of drugs.

2009-06-01

Full Text Available Objectives : This study was performed to developing orally administered analgesics and locally injected pharmacopuncture analgesics like opioids. Methods : Literary investigation on the origin of poppy (Papaver somniferum L and other narcotics was conducted to examine the potential of developing orally administered analgesics and locally injected pharmacopuncture analgesics. Opium is a gum-like mass derived from air-dried white fluid of immature fruit of the poppy. Opium contains approximately 20 types of alkaloids including morphine, codeine, thebaine, papaverine and others. Natural opioids and synthetic alkaloid derivatives are the constituents of opioid analgesics and their effects and side-effects depend on the peculiarities of receptors. An extreme caution is required in the selection of proper dosage, proper analgesic types, and indications for successful pain management. Results and Discussion : With the enactment of "Narcotic control protocol", herbs such as cannibis and poppy are no longer available for use by Korean medicine doctors, and these doctors are faced with difficulty in managing severe pain in the clinical environment. A systematic consideration is inevitable for overcoming the limitation on these analgesics.

Optimal perioperative pain control regimens remain challenging and opioid analgesics are commonly used. Preoperative nonsteroidal anti-inflammatory drug (NSAID administration has been shown to reduce postoperative narcotic requirements. This study sought to evaluate the efficacy of perioperative intravenous (IV ibuprofen on postoperative pain level and narcotic use in patients undergoing open or laparoscopic inguinal and/or umbilical hernia repair.Methods: A single center, randomized, double-blind placebo-controlled trial involving patients ≥18 years undergoing inguinal and/or umbilical hernia repair was performed. Patients were randomized to receive 800 mg of IV ibuprofen or placebo preoperatively. Outcomes assessed included postoperative pain medication required and visual analog scale (VAS pain scores.Results: Forty-eight adult male patients underwent inguinal and/or umbilical hernia repair. Patients receiving IV ibuprofen used more oxycodone/acetaminophen (32% vs 13% and IV hydromorphone (12% vs 8.7%, and fewer combinations of pain medications (44% vs 65.2% in the first two postoperative hours compared to placebo (p=0.556. The IV ibuprofen group had more patients pain free (28% vs 8.7%, p=0.087 and lower VAS scores (3.08±2.14 vs 3.95±1.54, p=0.134 at 2 hours postoperatively, compared to the placebo group, however, this was not statistically significant.

Delaveris, Gerd Jorunn M; Teige, Brita; Rogde, Sidsel

2014-05-01

The aim of the study was to explore differences and similarities between the various non-natural manners of death (accident, suicide, homicide) regarding toxicological findings in illicit drug users. Medicolegal autopsy reports from the Institute of Forensic Medicine University of Oslo concerning deaths from 2000 to 2009 were investigated. Those aged 20-59 whose manner of death was non-natural and who tested positive for any narcotic drug (morphine/heroin, amphetamines, ecstasy, cannabis, LSD, PCP, and high levels of GHB in addition to methadone and buprenorphine) were selected. All substance findings were registered and categorized (narcotics, ethanol, and medicinal products). Of the 1603 autopsies that met the selection criteria, 1204 were accidental intoxications, 122 accidents other than intoxication, 114 suicides by intoxication, 119 non-intoxication suicides, and 44 victims of homicide. Poly drug use was found in all manners of death. The drug profile as well as the mean number of substances (illicit drugs and medicinal products) varied from 2.9 to 4.6 substances per case, depending on the manner of death. Intoxication suicides had the highest number of substances and a total drug profile similar to accidental intoxications. Non-intoxication suicides had a total drug profile similar to homicide and accidents other than intoxication. The number of substances found per case increased during the decade, mainly due to increased findings of methadone, cannabis, amphetamines, and benzodiazepines. Methadone findings increased much more than buprenorphine. Methadone was found 20 times more often than buprenorphine in accidental intoxication cases. In summary, poly drug findings are common in adults who suffer a non-natural death while using illicit drugs. The different manners of death have some specific characteristics and significant differences regarding drug profile. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Medicinal chemistry is not limited to molecules, their structures and design but also highly cohesive to pharmacological activities. The potency of a molecule varies by its structure. Hence structural activity relationship is the sub-branch which deals with the estimation of ability of a molecule in depicting any pharmacological activity. In silico drug design is a novel technique which is employed in designing a molecule by using computer aided software’s and bringing a superior and potent molecule. In recent years, in silico drug design has been merged with medicinal chemistry especially by the techniques like ligand based strategy to isolate the required structures. By such strategic techniques, there are high chances of delivering high throughput screening which involves of screening large number of molecules in a very less time. Involvement of such techniques would be a boon for development of new drug entity as it can aid in development of newer, safe, effective and potent drug molecules. Hence, the present issue is aimed to emphasize the cohesion between in silico drug design and it significance in medicinal chemistry. The articles which would be published will mainly focus on the role of in silico drug design techniques in the development of molecules to target various disease and disorders. Molecules can from natural/ synthetic/semi synthetic origin. Articles will be a treasure box consisting of employment of computational methods for unprecedented molecules. The issue will be sure an endorsement for international readership and researchers.

Using Metabolomics to Investigate Biomarkers of Drug Addiction.

Ghanbari, Reza; Sumner, Susan

2018-02-01

Drug addiction has been associated with an increased risk for cancer, psychological complications, heart, liver, and lung disease, as well as infection. While genes have been identified that can mark individuals at risk for substance abuse, the initiation step of addiction is attributed to persistent metabolic disruptions occurring following the first instance of narcotic drug use. Advances in analytical technologies can enable the detection of thousands of signals in body fluids and excreta that can be used to define biochemical profiles of addiction. Today, these approaches hold promise for determining how exposure to drugs, in the absence or presence of other environmentally relevant factors, can impact human metabolism. We posit that these can lead to candidate biomarkers of drug dependence, treatment, withdrawal, or relapse. Copyright © 2017. Published by Elsevier Ltd.

A wide range of length and time scales are relevant to pharmacology, especially in drug development, drug design and drug delivery. Therefore, multi-scale computational modeling and simulation methods and paradigms that advance the linkage of phenomena occurring at these multiple scales have become increasingly important. Multi-scale approaches present in silico opportunities to advance laboratory research to bedside clinical applications in pharmaceuticals research. This is achievable through the capability of modeling to reveal phenomena occurring across multiple spatial and temporal scales, which are not otherwise readily accessible to experimentation. The resultant models, when validated, are capable of making testable predictions to guide drug design and delivery. In this review we describe the goals, methods, and opportunities of multi-scale modeling in drug design and development. We demonstrate the impact of multiple scales of modeling in this field. We indicate the common mathematical techniques employed for multi-scale modeling approaches used in pharmacology and present several examples illustrating the current state-of-the-art regarding drug development for: Excitable Systems (Heart); Cancer (Metastasis and Differentiation); Cancer (Angiogenesis and Drug Targeting); Metabolic Disorders; and Inflammation and Sepsis. We conclude with a focus on barriers to successful clinical translation of drug development, drug design and drug delivery multi-scale models.

Type 2 diabetes mellitus is a common metabolism disorder characterized by high glucose in the bloodstream, especially in the case of insulin resistance and relative insulin deficiency. Nowadays, it is very common in middle-aged people and involves such dangerous symptoms as increasing risk of stroke, obesity and heart failure. In Vietnam, besides the common treatment of insulin injection, some herbal medication is used but no unified optimum remedy for the disease yet exists and there is no production of antidiabetic drugs in the domestic market yet. In the development of nanomedicine at the present time, drug design is considered as an innovative tool for researchers to study the mechanisms of diseases at the molecular level. The aim of this article is to review some common protein targets involved in type 2 diabetes, offering a new idea for designing new drug candidates to produce antidiabetic drugs against type 2 diabetes for Vietnamese people.

The term "patient centered," "patient centric," or "patient centricity" is increasingly used in the scientific literature in a wide variety of contexts. Generally, patient centric medicines are recognized as an essential contributor to healthy aging and the overall patient's quality of life and life expectancy. Besides the selection of the appropriate type of drug substance and strength for a particular indication in a particular patient, due attention must be paid that the pharmaceutical drug product design is also adequately addressing the particular patient's needs, i.e., assuring adequate patient adherence and the anticipate drug safety and effectiveness. Relevant pharmaceutical design aspects may e.g., involve the selection of the route of administration, the tablet size and shape, the ease of opening the package, the ability to read the user instruction, or the ability to follow the recommended (in-use) storage conditions. Currently, a harmonized definition on patient centric drug development/design has not yet been established. To stimulate scientific research and discussions and the consistent interpretation of test results, it is essential that such a definition is established. We have developed a first draft definition through various rounds of discussions within an interdisciplinary AAPS focus group of experts. This publication summarizes the outcomes and is intended to stimulate further discussions with all stakeholders towards a common definition of patient centric pharmaceutical drug product design that is useable across all disciplines involved.

The fundamental properties of transdermal therapeutic patch as narcotic analgesics agent has been investigated. From the study of drug and ethanol release patterns from the fentanyl base (FB) patches through diffusion cell and hairless mouse skin, it was observed that the FB release patterns were largely affected by the content of vinyl acetate (VA) of ethylene-co-vinyl acetate (EVA) membrane, and volume fraction of ethanolic solution. Additionally, a variety of control membrane as a function of VA content were examined for swelling following equilibration with ethanolic solutions. Generally, ethanol was incorporated into a transdermal therapeutic device to enable the controlled delivery of enhancer and drug to the skin surface. In vitro skin permeation analysis of the control membrane showed that ethanol flux was linearly related to the ethanol volume fraction. This result was shown that drug permeability increased with increasing as the content of VA. But, the FB flux from saturated aqueous ethanol solutions increases until 80% ethanol volume fraction. Over 80% ethanol volume fraction, the FB flux through skin samples is independent of ethanol volume. These results showed that the decrease in skin permeation due to dehydration nis the dominant effect. 26 refs., 8 figs.

Transversus abdominis plane (TAP) blocks are increasingly being utilized in microvascular breast reconstruction. The implications of TAP blocks on specific reconstructive, patient and institutional outcomes remain to be fully elucidated. Patients undergoing abdominally-based microvascular breast reconstruction from 2015-2017 were reviewed. Length of stay, complications, narcotic consumption, donor-site pain and hospital expenses were compared between patients that did and those that did not receive TAP blocks with liposomal bupivacaine. Outcomes were subsequently compared in patients with elevated body mass index (BMI). Fifty patients (43.9%) received TAP blocks (27 [54.0%] under ultrasound guidance) and 64 patients (56.1%) did not. Patients with TAP blocks had significantly decreased oral and total narcotic consumption (p=0.0001 and pconsumption and postoperative pain compared to patients without TAP blocks. Patients with BMIconsumption or length of stay between the TAP versus no TAP block groups. TAP blocks with liposomal bupivacaine significantly reduce oral and total postoperative narcotic consumption as well as donor-site pain in all patients after abdominally-based microvascular breast reconstruction without increasing hospital expenses. TAP blocks additionally significantly decrease length of stay in patients with BMI≥25.

2010-11-01

In silico fragment-based drug design (FBDD) is a relatively new approach inspired by the success of the biophysical fragment-based drug discovery field. Here, we review the progress made by this approach in the last decade and showcase how it complements and expands the capabilities of biophysical FBDD and structure-based drug design to generate diverse, efficient drug candidates. Advancements in several areas of research that have enabled the development of in silico FBDD and some applications in drug discovery projects are reviewed. The reader is introduced to various computational methods that are used for in silico FBDD, the fragment library composition for this technique, special applications used to identify binding sites on the surface of proteins and how to assess the druggability of these sites. In addition, the reader will gain insight into the proper application of this approach from examples of successful programs. In silico FBDD captures a much larger chemical space than high-throughput screening and biophysical FBDD increasing the probability of developing more diverse, patentable and efficient molecules that can become oral drugs. The application of in silico FBDD holds great promise for historically challenging targets such as protein-protein interactions. Future advances in force fields, scoring functions and automated methods for determining synthetic accessibility will all aid in delivering more successes with in silico FBDD.

"Not for human consumption": a review of emerging designer drugs.

Science.gov (United States)

Musselman, Megan E; Hampton, Jeremy P

2014-07-01

Synthetic, or "designer" drugs, are created by manipulating the chemical structures of other psychoactive drugs so that the resulting product is structurally similar but not identical to illegal psychoactive drugs. Originally developed in the 1960s as a way to evade existing drug laws, the use of designer drugs has increased dramatically over the past few years. These drugs are deceptively packaged as "research chemicals," "incense," "bath salts," or "plant food," among other names, with labels that may contain warnings such as "not for human consumption" or "not for sale to minors." The clinical effects of most new designer drugs can be described as either hallucinogenic, stimulant, or opioid-like. They may also have a combination of these effects due to designer side-chain substitutions. The easy accessibility and rapid emergence of new designer drugs have created challenges for health care providers when treating patients presenting with acute toxicity from these substances, many of which can produce significant and/or life-threatening adverse effects. Moreover, the health care provider has no way to verify the contents and/or potency of the agent ingested because it can vary between packages and distributors. Therefore, a thorough knowledge of the available designer drugs, common signs and symptoms of toxicity associated with these agents, and potential effective treatment modalities are essential to appropriately manage these patients. © 2014 Pharmacotherapy Publications, Inc.

2012-01-01

Full Text Available Ocular diseases, such as, glaucoma, age-related macular degeneration (AMD, diabetic retinopathy, and retinitis pigmentosa require drug management in order to prevent blindness and affecting million of adults in USA and worldwide. There is an increasing need to develop devices for drug delivery to address ocular diseases. This study focuses on the design, simulation, and development of an implantable ocular drug delivery device consisting of micro-/nanochannels embedded between top and bottom covers with a drug reservoir made from polydimethylsiloxane (PDMS which is silicon-based organic and biodegradable polymer. Several simulations were carried out with six different micro-channel configurations in order to see the feasibility for ocular drug delivery applications. Based on the results obtained, channel design of osmotic I and osmotic II satisfied the diffusion rates required for ocular drug delivery. Finally, a prototype illustrating the three components of the drug delivery design is presented. In the future, the device will be tested for its functionality and diffusion characteristics.

Drug-induced apnea.

Science.gov (United States)

Boutroy, M J

1994-01-01

Drugs have been in the past and will in the future still be liable to induce apnea in neonates, infants and older children. At these different stages of development, the child may be abnormally vulnerable to respiratory disorders and apnea, and doses of drugs, without any abnormal side effects in adult patients, can be harmful in younger subjects. Drugs responsible for apnea during development are numerous, but more than half of the problems are induced by sedatives and hypnotics, among which phenothiazines, barbiturates, benzodiazepines (included transplacentally acquired) and general anesthetics are a few. Other pharmacological families are apnea inducers in the neonatal period and childhood: analgesics and opioid narcotics, agents acting at the levels of neuromuscular function and autonomic ganglia, and cardiovascular agents. The pathogenesis of these apneas depends on the disturbance of any mechanism responsible for the respiratory activity: medullary centers and brain stem structures, afferent influx to CNS, sleep stages, upper airways, lungs and respiratory muscles. At key stages such as birth and infancy, drugs may emphasize the particular sensitivity of the mechanisms responsible for inducing apnea. This might explain unexpected respiratory disorders during development.

Drug diversion by health care personnel poses a risk for serious patient harm. Public health identified 2 patients diagnosed with acute hepatitis C virus (HCV) infection who shared a common link with a hospital. Further investigation implicated a drug-diverting, HCV-infected surgical technician who was subsequently employed at an ambulatory surgical center. Patients at the 2 facilities were offered testing for HCV infection if they were potentially exposed. Serum from the surgical technician and patients testing positive for HCV but without evidence of infection before their surgical procedure was further tested to determine HCV genotype and quasi-species sequences. Parenteral medication handling practices at the 2 facilities were evaluated. The 2 facilities notified 5970 patients of their possible exposure to HCV, 88% of whom were tested and had results reported to the state public health departments. Eighteen patients had HCV highly related to the surgical technician's virus. The surgical technician gained unauthorized access to fentanyl owing to limitations in procedures for securing controlled substances. Public health surveillance identified an outbreak of HCV infection due to an infected health care provider engaged in diversion of injectable narcotics. The investigation highlights the value of public health surveillance in identifying HCV outbreaks and uncovering a method of drug diversion and its impacts on patients.

Protein tethering enables rapid and label-free SERS platform for screening drugs of abuse (Conference Presentation)

2017-02-01

A quick, cost-effective method for detection of drugs of abuse in biological fluids would be of great value in healthcare, law enforcement, and home testing applications. The alarming rise in narcotics abuse has led to considerable focus on developing potent and versatile analytical tools that can address this societal problem. While laboratory testing plays a key role in the current detection of drug misuse and the evaluation of patients with drug induced intoxication, these typically require expensive reagents and trained personnel, and may take hours to complete. Thus, a significant unmet need is to engineer a facile method that can rapidly detect drugs with little sample preparation, especially the bound fraction that is typically dominant in the blood stream. Here we report an approach that combines the exquisite sensitivity of surface enhanced Raman spectroscopy (SERS) and a facile protein tethering mechanism to reliably detect four different classes of drugs, barbiturate, benzodiazepine, amphetamine and benzoylecgonine. The proposed approach harnesses the reliable and specific attachment of proteins to both drugs and nanoparticle to facilitate the enhancement of spectral markers that are sensitive to the presence of the drugs. In conjunction with chemometric tools, we have shown the ability to quantify these drugs lower than levels achievable by existing clinical immunoassays. Through molecular docking simulations, we also probe the mechanistic underpinnings of the protein tethering approach, opening the door to detection of a broad class of narcotics in biological fluids within a few minutes as well as for groundwater analysis and toxin detection.

In each audit four operating rooms were visited twice a week. Syringes were checked for standard drug labelling for narcotic and non narcotic preparations. Drug trolley was checked for any expired drugs and whether the trolley was locked in case of operating room (OR) where list was ended or was on hold. Any unattended drug was noted and Induction room was checked twice weekly for accurate drug inventory and for standard drug storage recommendations. Labels were according to standard in non narcotic drugs on 25% syringes in first audit and 63% in second audit, likewise, narcotics labels were according to standards in 41% in first and 57% in second audit. Unattended drugs were present once in first and twice in second audit. There was 100% compliance in other drug storage policy parameters in both audits. Poor compliance of drug labelling standards for both narcotic and non narcotic drugs was present. However, second audit revealed improvement in all areas of drug handling. Dissemination of policies and reminders are important for continuing improvement in use of medication within operation room and within induction room floor stock.

Full Text Available BACKGROUND: Although confinement in drug detoxification ("detox" and re-education through labor (RTL centers is the most common form of treatment for drug dependence in China, little has been published about the experience of drug users in such settings. We conducted an assessment of the impact of detention on drug users' access to HIV prevention and treatment services and consequent threats to fundamental human rights protections. METHODS AND FINDINGS: Chinese government HIV and anti-narcotics legislation and policy documents were reviewed, and in-depth and key informant interviews were conducted with 19 injection drug users (IDUs and 20 government and nongovernmental organization officials in Nanning and Baise, Guangxi Province. Significant contradictions were found in HIV and antinarcotics policies, exemplified by the simultaneous expansion of community-based methadone maintenance therapy and the increasing number of drug users detained in detox and RTL center facilities. IDU study participants reported, on average, having used drugs for 14 y (range 8-23 y and had been confined to detox four times (range one to eight times and to RTL centers once (range zero to three times. IDUs expressed an intense fear of being recognized by the police and being detained, regardless of current drug use.

Computer simulations have become a widely used and powerful tool to study the behaviour of many-particle and many-interaction systems and processes such as nucleic acid dynamics, drug-DNA interactions, enzymatic processes, membrane, antibiotics. The increased reliability of computational techniques has made possible to plane a bottom-up approach in drug design, i.e. designing molecules with improved properties starting from the knowledge of the molecular mechanisms. However, the in silico techniques have to face the fact that the number of degrees of freedom involved in biological systems is very large while the time scale of several biological processes is not accessible to standard simulations. Algorithms and methods have been developed and are still under construction to bridge these gaps. Here we review the activities of our group focussed on the time-scale bottleneck and, in particular, on the use of the meta dynamics scheme that allows the investigation of rare events in reasonable computer time without reducing the accuracy of the calculation. In particular, we have devoted particular attention to the characterization at microscopic level of translocation of antibiotics through membrane pores, aiming at the identification of structural and dynamical features helpful for a rational drug design.

Full Text Available Introduction: Narcotic drug abuse and illicit use of drugs is a major, complicated multifactorial phenomenon affecting most of the societies today. Incidence of drug abuse among adolescents is very high. Adolescents become addicted to substances more quickly than adults. The aim of this study was to assess the pattern of drug abuse among male adolescents in Hamadan. Methods: This study was a descriptive study and samples (n=400 were collected on the basis of snowball sampling method. Information was collected individually through completion of a researcher-designed questionnaire including demographic and epidemiological indices, perceived familial support, religiosity, and locus of control. Results: The results showed that smoking (93%, alcohol (92.5%, marijuana (64.3%, and opium (57.8% use were very high, while LSD (4.8% and Cocaine(2.3% use was rare. 77.8 % of adolescents began drug abuse between 12 and 18 years of age. Moreover, sensation seeking (26.5%, individual interest (24.8%, and peer pressure (22%, were the main reasons for drug abuse. Conclusion: As initial smoking, alcohol and marijuana use play an important role in determining the future addiction of adolescents to narcotics, yearly surveillance programs in the country and evaluation of etiological factors of narcotic addiction need to be studied carefully. All of the preventive and school programs designed for the young should take into account environmental, demographic and policy factors in addition to personal factors so that the programs have a maximum effect.

Background The increased use of opioid analgesics, sedative hypnotics and stimulants, coupled with the associated risks of overdose have raised concerns around the inappropriate prescribing of these monitored drugs. We assessed the impact of new legislation, the Narcotics Safety and Awareness Act, and a centralized Narcotics Monitoring System (implemented November 2011 and May 2012, respectively), on the dispensing of prescriptions suggestive of misuse. Methods We conducted a time series analysis of publicly funded prescriptions for opioids, benzodiazepines and stimulants dispensed monthly in Ontario from January 2007 to May 2013, based on information in the Ontario Public Drug Benefit Database. In the primary analysis, a prescription was deemed potentially inappropriate if it was dispensed within 7 days of an earlier prescription and was for at least 30 tablets of a drug in the same class as the earlier prescription, but originated from a different physician and a different pharmacy. Results After enactment of the new legislation, the prevalence of potentially inappropriate opioid prescriptions decreased by 12.5% in 6 months (from 1.6% in October 2011 to 1.4% in April 2012; p = 0.01). No further significant change was observed after the introduction of the narcotic monitoring system (p = 0.8). By May 2013, the prevalence had dropped to 1.0%. Inappropriate benzodiazepine prescribing was significantly influenced by both the legislation (p significantly influenced by the introduction of the monitoring system in May 2012, falling from 0.7% in April 2012 to 0.3% in May 2013 (p = 0.02). Interpretation For a select group of drugs prone to misuse and diversion, legislation and a prescription monitoring program reduced the prevalence of prescriptions suggestive of misuse. This suggests that regulatory interventions can promote appropriate prescribing which could potentially be applied to other jurisdictions and drugs of concern. PMID:25485251

Drug Design and Emotion

Science.gov (United States)

Folkers, Gerd; Wittwer, Amrei

2007-11-01

"Geteiltes Leid ist halbes Leid." The old German proverb reflects the fact that sharing a bad emotion or feeling with someone else may lower the psychological strain of the person experiencing sorrow, mourning or anger. On the other hand the person showing empathy will take literally a load from its counterpart, up to physiological reaction of the peripheral and central nervous pain system. Though subjective, mental and physical states can be shared. Visual perception of suffering may be important but also narrative description plays a role, all our senses are mixing in. It is hypothetized that literature, art and humanities allow this overlap. A change of mental states can lead to empirically observable effects as it is the case for the effect of role identity or placebo on pain perception. Antidepressants and other therapeutics are another choice to change the mental and bodily states. Their development follows today's notion of "rationality" in the design of therapeutics and is characterized solely by an atomic resolution approach to understand drug activity. Since emotional states and physiological states are entangled, given the difficulty of a physical description of emotion, the future rational drug design should encompass mental states as well.

Anti-malarial Drug Design by Targeting Apicoplasts: New Perspectives

Directory of Open Access Journals (Sweden)

Avinaba Mukherjee

2016-03-01

Full Text Available Objectives: Malaria has been a major global health problem in recent times with increasing mortality. Current treatment methods include parasiticidal drugs and vaccinations. However, resistance among malarial parasites to the existing drugs has emerged as a significant area of concern in anti-malarial drug design. Researchers are now desperately looking for new targets to develop anti-malarials drug which is more target specific. Malarial parasites harbor a plastid-like organelle known as the ‘apicoplast’, which is thought to provide an exciting new outlook for the development of drugs to be used against the parasite. This review elaborates on the current state of development of novel compounds targeted againstemerging malaria parasites. Methods: The apicoplast, originates by an endosymbiotic process, contains a range of metabolic pathways and housekeeping processes that differ from the host body and thereby presents ideal strategies for anti-malarial drug therapy. Drugs are designed by targeting the unique mechanism of the apicoplasts genetic machinery. Several anabolic and catabolic processes, like fatty acid, isopenetyl diphosphate and heme synthess in this organelle, have also been targeted by drugs. Results: Apicoplasts offer exciting opportunities for the development of malarial treatment specific drugs have been found to act by disrupting this organelle’s function, which wouldimpede the survival of the parasite. Conclusion: Recent advanced drugs, their modes of action, and their advantages in the treatment of malaria by using apicoplasts as a target are discussed in this review which thought to be very useful in desigining anti-malarial drugs. Targetting the genetic machinery of apicoplast shows a great advantange regarding anti-malarial drug design. Critical knowledge of these new drugs would give a healthier understanding for deciphering the mechanism of action of anti-malarial drugs when targeting apicoplasts to overcome drug

Morphine sulfate and methadone hydrochloride exhibit very different half-lives but are described as having an analgesic potency of one. The use of a drug like methadone may provide prolonged and constant analgesia in the perioperative setting. This double-blinded investigation used methadone and morphine intraoperatively and measured pain scores and narcotic requirements in the first 24 hours postoperatively. Thirty American Society of Anesthesiology (ASA) patients, physical status I through III, between the ages of 18 to 65 years were scheduled for orthopedic surgery and randomly assigned to receive morphine or methadone at 0.30 mg/kg. Fifteen patients received morphine and fifteen patients received methadone. There was no significant difference between the two groups in terms of age, height, weight, and ASA status. No statistically significant difference was observed among the two groups between the amount of analgesic requirements postoperatively or in the visual analogue scale pain score.

Drug Policy and Indigenous Peoples.

Burger, Julian; Kapron, Mary

2017-06-01

This paper identifies the principal concerns of indigenous peoples with regard to current international treaties on certain psychoactive substances and policies to control and eradicate their production, trafficking, and sale. Indigenous peoples have a specific interest in the issue since their traditional lands have become integrated over time into the large-scale production of coca, opium poppy, and cannabis crops, in response to high demand from the American and European markets, among others. As a consequence, indigenous peoples are persecuted because of their traditional use of these and other plant-based narcotics and hallucinogens. They are also victims of the drug producers who remove them from their lands or forcibly recruit them into the production process. As indigenous peoples are caught in the violent world of illicit drug production, law enforcement often targets them first, resulting in disproportionate rates of criminalization and incarceration.

Full Text Available Narcotics is a highly addictive drug that acts as a stimulant or depresant for the central nervous system. The prevalence of various diseases found to be higher in the group of drug users then those who not use drugs such as endocarditis, hepatitis and HIV. Further evidence that the drug effects the oral health which includes the effect of the hard tissues by increased incidence of caries and periodontitis and the effect of the soft tissues in the form of leukoplakia and oral mucosal fibrosis, reduced production, especially the parotid salivary glands in amphetamine and cannabis users. In addition to the drug is a predisposing of oral infections such as candidiasis and gingivitis. Reduced volume of saliva on abusers may result in reduced immune function of saliva in maintaining oral health. Consequently the drug abusers increased number of bacteria and fungi in the oral cavity, including anaerobic bacteria and Candida albicans, especially in cases of abuse of cannabis. Gingival plaque formation and the growing colonies of anaerobic bacteria may increase the occurrence of gingivitis in the drug abusers. Lack of awareness of drug abusers in oral hygiene causing the gingivitis develops into periodontitis followed by alveolar bone loss.

Patient centric drug product design in modern drug delivery as an opportunity to increase safety and effectiveness.

Science.gov (United States)

Stegemann, Sven

2018-06-01

The advances in drug delivery technologies have enabled pharmaceutical scientists to deliver a drug through various administration routes and optimize the drug release and absorption. The wide range of drug delivery systems and dosage forms represent a toolbox of technology for the development of pharmaceutical drug products but might also be a source of medication errors and nonadherence. Patient centric drug product development is being suggested as an important factor to increase therapeutic outcomes. Areas covered: Patients have impaired health and potentially disabilities and they are not medical or pharmaceutical experts but are requested to manage complex therapeutic regimens. As such the application of technology should also serve to reduce complexity, build on patients' intuition and ease of use. Patients form distinct populations based on the targeted disease, disease cluster or age group with specific characteristics or therapeutic contexts. Expert opinion: Establishing a target product and patient profile is essential to guide drug product design development. Including the targeted patient populations in the process is a prerequisite to achieve patient-centric pharmaceutical drug product design. Addressing the needs early on in the product design process, will create more universal design, avoiding the necessity for multiple product presentations to cover the different patient populations.

2018-01-01

Generative artificial intelligence models present a fresh approach to chemogenomics and de novo drug design, as they provide researchers with the ability to narrow down their search of the chemical space and focus on regions of interest. We present a method for molecular de novo design that utilizes generative recurrent neural networks (RNN) containing long short-term memory (LSTM) cells. This computational model captured the syntax of molecular representation in terms of SMILES strings with close to perfect accuracy. The learned pattern probabilities can be used for de novo SMILES generation. This molecular design concept eliminates the need for virtual compound library enumeration. By employing transfer learning, we fine-tuned the RNN's predictions for specific molecular targets. This approach enables virtual compound design without requiring secondary or external activity prediction, which could introduce error or unwanted bias. The results obtained advocate this generative RNN-LSTM system for high-impact use cases, such as low-data drug discovery, fragment based molecular design, and hit-to-lead optimization for diverse drug targets. © 2017 The Authors.

Medicinal chemistry is a multidisciplinary subject that integrates knowledge from a variety of fields of science, including, but not limited to, chemistry, biology, and physics. The area of drug design involves the cooperative work of scientists with a diverse range of backgrounds and technical skills, trying to tackle complex problems using an integration of approaches and methods. One important contribution to this field comes from physics through studies that attempt to identify and quantify the molecular interactions between small molecules (drugs) and biological targets (receptors), such as the forces that govern the interactions, the thermodynamics of the drug-receptor interactions, and so on. In this context, the interfaces of physics, medicinal chemistry, and drug design are of vital importance for the development of drugs that not only have the right chemistry but also the right intermolecular properties to interact at the macromolecular level, providing useful information about the principles and molecular mechanisms underlying the therapeutic action of drugs. This article highlights some of the most important connections between physics and medicinal chemistry in the design of new drugs.

Fragment-based drug discovery (FBDD) has caused a revolution in the process of drug discovery and design, with many FBDD leads being developed into clinical trials or approved in the past few years. Compared with traditional high-throughput screening, it displays obvious advantages such as efficiently covering chemical space, achieving higher hit rates, and so forth. In this review, we focus on the most recent developments of FBDD for improving drug discovery, illustrating the process and the importance of FBDD. In particular, the computational strategies applied in the process of FBDD and molecular-docking programs are highlighted elaborately. In most cases, docking is used for predicting the ligand-receptor interaction modes and hit identification by structurebased virtual screening. The successful cases of typical significance and the hits identified most recently are discussed.

Fragment-based drug design (FBDD) has become an effective methodology for drug development for decades. Successful applications of this strategy brought both opportunities and challenges to the field of Pharmaceutical Science. Recent progress in the computational fragment-based drug design provide an additional approach for future research in a time- and labor-efficient manner. Combining multiple in silico methodologies, computational FBDD possesses flexibilities on fragment library selection, protein model generation, and fragments/compounds docking mode prediction. These characteristics provide computational FBDD superiority in designing novel and potential compounds for a certain target. The purpose of this review is to discuss the latest advances, ranging from commonly used strategies to novel concepts and technologies in computational fragment-based drug design. Particularly, in this review, specifications and advantages are compared between experimental and computational FBDD, and additionally, limitations and future prospective are discussed and emphasized.

2015-03-01

The aim of the study was to provide information on illicit drug abuse stigmata and general pathological findings among an adult narcotic drug-using population aged 20 to 59 years whose death was nonnatural. A total of 1603 medicolegal autopsy reports from 2000 to 2009 concerning cases positive for morphine, heroin, amphetamines, ecstasy, cannabis, LSD (lysergic acid diethylamide), PCP (phencyclidine), and high levels of GHB (γ-hydroxybutyric acid) in addition to methadone and buprenorphine were investigated. Reported findings of hepatitis, portal lymphadenopathy, recent injection marks, drug user's equipment, and numbers of significant pathological conditions were registered and analyzed according to cases positive for opiates, opioids (OPs), and central nervous system (CNS)-stimulating illicit drugs, respectively. Of the selected cases, 1305 were positive for one or more opiate or OP. Cases positive for OPs had significantly more findings of noninfectious pathological conditions. Hepatitis, portal lymphadenopathy, recent injections marks findings of drug user's equipment were all findings found more frequently among the opiate OP-positive individuals. Portal lymphadenopathy was significantly more often found in cases with hepatitis than in cases with other or no infection. In the population positive for CNS stimulants, hepatitis recent injection marks were more frequent findings than in the CNS stimulant-negative group, irrespective of whether they were opiate OP positive or negative.

Prescription drugs are the highest single cost component for employees' benefits packages in Canada. While industry literature considers cost-containment for prescription drug costs to be a priority for insurers and employers, the implementation of cost-containment measures for private drug plans in Canada remains more of a myth than a reality. Through 18 semi-structured phone interviews conducted with experts from private sector companies, unions, insurers and plan advisors, this study explores the reasons behind this incapacity to implement cost-containment measures by examining how private sector employers negotiate drug benefit design in unionized settings. Respondents were asked questions on how employee benefits are negotiated; the relationships between the players who influence drug benefit design; the role of these players' strategies in influencing plan design; the broad system that underpins drug benefit design; and the potential for a universal pharmacare program in Canada. The study shows that there is consensus about the need to educate employees and employers, more collaboration and data-sharing between these two sets of players, and for external intervention from government to help transform established norms in terms of private drug plan design.

The Impact of Drug Trafficking on Informal Security Actors in Kenya

Directory of Open Access Journals (Sweden)

Moritz Schuberth

2014-01-01

Full Text Available The Kenyan state is currently under pressure from two sides: First, numerous non-state armed groups have taken over the provision of security in areas where the state is practically absent. Second, drug-trafficking organizations are gaining ground as the country is increasingly being used as a major transit hub for narcotics. This article investigates the relationship between drug trafficking and informal security provision in Kenya and draws analogies from comparable experiences in Latin America and West Africa. Field research in Kenya has demonstrated that profit-oriented, informal security actors in Mombasa work for drug lords, while their counterparts in Nairobi are more likely to be hired by politicians. Moreover, faith-based vigilante groups in both cities appear to be less susceptible to external manipulation by drug traffickers. The article concludes by considering the potential consequences of an expansion of the drug trade in Kenya.

Drug-drug interactions (DDIs) are common in clinical care and pose serious risks for patients. Electronic health records display DDI alerts that can influence prescribers, but the interface design of DDI alerts has largely been unstudied. In this study, the objective was to apply human factors engineering principles to alert design. It was hypothesized that redesigned DDI alerts would significantly improve prescribers' efficiency and reduce prescribing errors. In a counterbalanced, crossover study with prescribers, two DDI alert designs were evaluated. Department of Veterans Affairs (VA) prescribers were video recorded as they completed fictitious patient scenarios, which included DDI alerts of varying severity. Efficiency was measured from time-stamped recordings. Prescribing errors were evaluated against predefined criteria. Efficiency and prescribing errors were analyzed with the Wilcoxon signed-rank test. Other usability data were collected on the adequacy of alert content, prescribers' use of the DDI monograph, and alert navigation. Twenty prescribers completed patient scenarios for both designs. Prescribers resolved redesigned alerts in about half the time (redesign: 52 seconds versus original design: 97 seconds; p<.001). Prescribing errors were not significantly different between the two designs. Usability results indicate that DDI alerts might be enhanced by facilitating easier access to laboratory data and dosing information and by allowing prescribers to cancel either interacting medication directly from the alert. Results also suggest that neither design provided adequate information for decision making via the primary interface. Applying human factors principles to DDI alerts improved overall efficiency. Aspects of DDI alert design that could be further enhanced prior to implementation were also identified.

The Open Form Inducer Approach for Structure-Based Drug Design.

Directory of Open Access Journals (Sweden)

Daniel Ken Inaoka

Full Text Available Many open form (OF structures of drug targets were obtained a posteriori by analysis of co-crystals with inhibitors. Therefore, obtaining the OF structure of a drug target a priori will accelerate development of potent inhibitors. In addition to its small active site, Trypanosoma cruzi dihydroorotate dehydrogenase (TcDHODH is fully functional in its monomeric form, making drug design approaches targeting the active site and protein-protein interactions unrealistic. Therefore, a novel a priori approach was developed to determination the TcDHODH active site in OF. This approach consists of generating an "OF inducer" (predicted in silico to bind the target and cause steric repulsion with flexible regions proximal to the active site that force it open. We provide the first proof-of-concept of this approach by predicting and crystallizing TcDHODH in complex with an OF inducer, thereby obtaining the OF a priori with its subsequent use in designing potent and selective inhibitors. Fourteen co-crystal structures of TcDHODH with the designed inhibitors are presented herein. This approach has potential to encourage drug design against diseases where the molecular targets are such difficult proteins possessing small AS volume. This approach can be extended to study open/close conformation of proteins in general, the identification of allosteric pockets and inhibitors for other drug targets where conventional drug design approaches are not applicable, as well as the effective exploitation of the increasing number of protein structures deposited in Protein Data Bank.

Medicinal plants are the main natural pools for the discovery and development of new drugs. In the modern era of computer-aided drug designing (CADD), there is need of prompt efforts to design and construct useful database management system that allows proper data storage, retrieval and management with user-friendly interface. An inclusive database having information about classification, activity and ready-to-dock library of medicinal plant's phytochemicals is therefore required to assist the researchers in the field of CADD. The present work was designed to merge activities of phytochemicals from medicinal plants, their targets and literature references into a single comprehensive database named as Medicinal Plants Database for Drug Designing (MPD3). The newly designed online and downloadable MPD3 contains information about more than 5000 phytochemicals from around 1000 medicinal plants with 80 different activities, more than 900 literature references and 200 plus targets. The designed database is deemed to be very useful for the researchers who are engaged in medicinal plants research, CADD and drug discovery/development with ease of operation and increased efficiency. The designed MPD3 is a comprehensive database which provides most of the information related to the medicinal plants at a single platform. MPD3 is freely available at: http://bioinform.info .

Crisp, Catrina C; Khan, Madiha; Lambers, Donna L; Westermann, Lauren B; Mazloomdoost, Donna M; Yeung, Jennifer J; Kleeman, Steven D; Pauls, Rachel N

This study aimed to determine the effect of intravenous acetaminophen versus placebo on postoperative pain, satisfaction with pain control, and narcotic use after vaginal reconstructive surgery. This was an institutional review board-approved, double-blind placebo-controlled randomized trial. Women scheduled for reconstructive surgery including vaginal hysterectomy and vaginal vault suspension were enrolled. Subjects received 1000 mg of intravenous acetaminophen or 100 mL placebo every 6 hours for 24 hours. Pain and satisfaction with pain control were assessed using visual analog scales and a numeric rating scale. Visual analog scales were collected at 18 and 24 hours postoperatively and at discharge. A sample size calculation determined 90 subjects would be required to detect a 30% reduction in postoperative narcotic use with 80% power and significance level of 0.05. One hundred subjects were enrolled. There were no differences in demographics or surgical data and no difference in narcotic consumption at multiple evaluation points. At 18 hours postoperative, median pain scores at rest were 27.0 (interquartile range, 35.0) for acetaminophen and 35.0 (interquartile range, 44.5) for placebo, finding no difference (P = 0.465). Furthermore, pain with activity and numeric rating scale-assessed pain scales were similar (P = 0.328; P = 0.597). Although satisfaction with pain control was high overall (91.5), no difference was noted. Patients undergoing vaginal reconstructive surgery receiving perioperative intravenous acetaminophen did not experience a decrease in narcotic requirements or postoperative pain when compared with placebo. Reassuringly, pain scores were low and satisfaction with pain control was high for all subjects. The general use of this medication is not supported in these surgical patients.

Connecting drug delivery reality to smart materials design.

Science.gov (United States)

Grainger, David W

2013-09-15

Inflated claims to both design and mechanistic novelty in drug delivery and imaging systems, including most nanotechnologies, are not supported by the generally poor translation of these systems to clinical efficacy. The "form begets function" design paradigm is seductive but perhaps over-simplistic in translation to pharmaceutical efficacy. Most innovations show few clinically important distinctions in their therapeutic benefits in relevant preclinical disease and delivery models, despite frequent claims to the contrary. Long-standing challenges in drug delivery issues must enlist more realistic, back-to-basics approaches to address fundamental materials properties in complex biological systems, preclinical test beds, and analytical methods to more reliably determine fundamental pharmaceutical figures of merit, including drug carrier purity and batch-batch variability, agent biodistribution, therapeutic index (safety), and efficacy.

Computer-aided drug design at Boehringer Ingelheim

Science.gov (United States)

Muegge, Ingo; Bergner, Andreas; Kriegl, Jan M.

2017-03-01

Computer-Aided Drug Design (CADD) is an integral part of the drug discovery endeavor at Boehringer Ingelheim (BI). CADD contributes to the evaluation of new therapeutic concepts, identifies small molecule starting points for drug discovery, and develops strategies for optimizing hit and lead compounds. The CADD scientists at BI benefit from the global use and development of both software platforms and computational services. A number of computational techniques developed in-house have significantly changed the way early drug discovery is carried out at BI. In particular, virtual screening in vast chemical spaces, which can be accessed by combinatorial chemistry, has added a new option for the identification of hits in many projects. Recently, a new framework has been implemented allowing fast, interactive predictions of relevant on and off target endpoints and other optimization parameters. In addition to the introduction of this new framework at BI, CADD has been focusing on the enablement of medicinal chemists to independently perform an increasing amount of molecular modeling and design work. This is made possible through the deployment of MOE as a global modeling platform, allowing computational and medicinal chemists to freely share ideas and modeling results. Furthermore, a central communication layer called the computational chemistry framework provides broad access to predictive models and other computational services.

Fragment-based drug design.

Science.gov (United States)

Feyfant, Eric; Cross, Jason B; Paris, Kevin; Tsao, Désirée H H

2011-01-01

Fragment-based drug design (FBDD), which is comprised of both fragment screening and the use of fragment hits to design leads, began more than 15 years ago and has been steadily gaining in popularity and utility. Its origin lies on the fact that the coverage of chemical space and the binding efficiency of hits are directly related to the size of the compounds screened. Nevertheless, FBDD still faces challenges, among them developing fragment screening libraries that ensure optimal coverage of chemical space, physical properties and chemical tractability. Fragment screening also requires sensitive assays, often biophysical in nature, to detect weak binders. In this chapter we will introduce the technologies used to address these challenges and outline the experimental advantages that make FBDD one of the most popular new hit-to-lead process.

Intratumor heterogeneity alters most effective drugs in designed combinations.

Zhao, Boyang; Hemann, Michael T; Lauffenburger, Douglas A

2014-07-22

The substantial spatial and temporal heterogeneity observed in patient tumors poses considerable challenges for the design of effective drug combinations with predictable outcomes. Currently, the implications of tissue heterogeneity and sampling bias during diagnosis are unclear for selection and subsequent performance of potential combination therapies. Here, we apply a multiobjective computational optimization approach integrated with empirical information on efficacy and toxicity for individual drugs with respect to a spectrum of genetic perturbations, enabling derivation of optimal drug combinations for heterogeneous tumors comprising distributions of subpopulations possessing these perturbations. Analysis across probabilistic samplings from the spectrum of various possible distributions reveals that the most beneficial (considering both efficacy and toxicity) set of drugs changes as the complexity of genetic heterogeneity increases. Importantly, a significant likelihood arises that a drug selected as the most beneficial single agent with respect to the predominant subpopulation in fact does not reside within the most broadly useful drug combinations for heterogeneous tumors. The underlying explanation appears to be that heterogeneity essentially homogenizes the benefit of drug combinations, reducing the special advantage of a particular drug on a specific subpopulation. Thus, this study underscores the importance of considering heterogeneity in choosing drug combinations and offers a principled approach toward designing the most likely beneficial set, even if the subpopulation distribution is not precisely known.

Despite the value of 12-step meetings, few studies have examined factors associated with attendance among those living with HIV/AIDS, such as the impact of HIV disease severity and demographics. This study examines predisposing characteristics, enabling resources and need on attendance at Alcoholic Anonymous (AA) and Narcotics Anonymous (NA) meetings among those living with HIV/AIDS and alcohol problems. Secondary analysis of prospective data from the HIV-Longitudinal Interrelationships of Viruses and Ethanol study, a cohort of 400 adults living with HIV/AIDS and alcohol problems. Factors associated with AA/NA attendance were identified using the Anderson model for vulnerable populations. Generalized estimating equation logistic regression models were fit to identify factors associated with self-reported AA/NA attendance. At study entry, subjects were 75% male, 12% met diagnostic criteria for alcohol dependence, 43% had drug dependence and 56% reported attending one or more AA/NA meetings (past 6 months). In the adjusted model, female gender negatively associated with attendance, as were social support systems that use alcohol and/or drugs, while presence of HCV antibody, drug dependence diagnosis, and homelessness associated with higher odds of attendance. Non-substance abuse related barriers to AA/NA group attendance exist for those living with HIV/AIDS, including females and social support systems that use alcohol and/or drugs. Positive associations of homelessness, HCV infection and current drug dependence were identified. These findings provide implications for policy makers and treatment professionals who wish to encourage attendance at 12-step meetings for those living with HIV/AIDS and alcohol or other substance use problems.

Synthetic cathinone “bath salts”: the mechanism of action, toxicological aspects, clinic, dependence development

Directory of Open Access Journals (Sweden)

Antsyborov A.V.

2017-05-01

Full Text Available according to the authors synthetic cathinone is a new class of designer drugs with psychoactive effect at the peak of intoxication which can cause hallucinatory disorders, acute paranoid disorders of psychotic level, the development of delirious disorders, affective disorders comparable to cocaine, methylenedioxymethamphetamine (MDMA and other drugs with amphetamine-like effect. The first reports of synthetic cathinone appeared in early 2009. On the black market, these substances were marketed as «bath salts». The legislation of the European countries have been carrying these substances to the drug since 2010, in the United States synthetic cathinone has been included in the list of narcotic substances since 2011, in the Russian Federation, these substances can be attributed to narcotic according to the Decree of the RF Government dated 31 December 2009 №1186 «About modification of some resolutions of the Government of the Russian Federation on issues related to trafficking in narcotic drugs». Recent clinical studies indicate dysregulation effect of synthetic cathinone’s on central monoamine system, which is one of the main mechanisms of synthetic cathinone’s action, and is the basis of behavioral disorders due to use. The review provides data about the chemical structure of synthetic cathinone’s, mechanisms of addiction, toxicology, clinical aspects of use.

2014-05-15

The availability of high-quality (13)C-labelled internal standards will improve accurate quantification of narcotics and drugs in biological samples. Thus, the synthesis of 10 [(13)C6]-labelled phenethylamine derivatives, namely amphetamine, methamphetamine, 3,4-methylenedioxyamphetamine, 3,4-methylenedioxymethamphetamine, 3,4-methylenedioxy-N-ethylamphetamine, 4-methoxyamphetamine, 4-methoxymethamphetamine, 3,5-dimethoxyphenethylamine 4-bromo-2,5-dimethoxyphenethylamine and 2,5-dimethoxy-4-iodophenethylamine, have been undertaken. [(13)C6]-Phenol proved to be an excellent starting material for making (13)C-labelled narcotic substances in the phenethylamine class, and a developed Stille-type coupling enabled an efficient synthesis of the 3,4-methylenedioxy and 4-methoxy derivatives. The pros and cons of alternative routes and transformations are also discussed. The [(13)C6]-labelled compounds are intended for use as internal standards in forensic analysis, health sciences and metabolomics studies by gas chromatography-mass spectrometry and liquid chromatography-tandem mass spectrometry.

New designer drugs (synthetic cannabinoids and synthetic cathinones): review of literature.

Science.gov (United States)

Cottencin, Olivier; Rolland, Benjamin; Karila, Laurent

2014-01-01

New designer drugs (synthetic cannabinoids and synthetic cathinones) are new "legal highs" that are sold online for recreational public or private use. Synthetic cannabinoids are psychoactive herbal and chemical products that mimic the effects of cannabis when used. These drugs are available on the Internet or in head shops as incense or air fresheners to circumvent the law. Cathinone is a naturally occurring beta-ketone amphetamine analog found in the leaves of the Catha edulis plant. Synthetic cathinones are phenylalkylamine derivatives that may possess amphetamine-like properties. These drugs are sold online as bath salts. Designer drugs are often labeled as "not for human consumption" to circumvent drug abuse legislation. The absence of legal risks, the ease of obtaining these drugs, the moderate cost, and the availability via the Internet are the main features that attract users, but the number of intoxicated people presenting with emergencies is increasing. There is evidence that negative health and social consequences may affect recreational and chronic users. The addictive potential of designer drugs is not negligible.

Cannabis as a substitute for prescription drugs – a cross-sectional study

Science.gov (United States)

Corroon, James M; Mischley, Laurie K; Sexton, Michelle

2017-01-01

Background The use of medical cannabis is increasing, most commonly for pain, anxiety and depression. Emerging data suggest that use and abuse of prescription drugs may be decreasing in states where medical cannabis is legal. The aim of this study was to survey cannabis users to determine whether they had intentionally substituted cannabis for prescription drugs. Methods A total of 2,774 individuals were a self-selected convenience sample who reported having used cannabis at least once in the previous 90 days. Subjects were surveyed via an online anonymous questionnaire on cannabis substitution effects. Participants were recruited through social media and cannabis dispensaries in Washington State. Results A total of 1,248 (46%) respondents reported using cannabis as a substitute for prescription drugs. The most common classes of drugs substituted were narcotics/opioids (35.8%), anxiolytics/benzodiazepines (13.6%) and antidepressants (12.7%). A total of 2,473 substitutions were reported or approximately two drug substitutions per affirmative respondent. The odds of reporting substituting were 4.59 (95% confidence interval [CI], 3.87–5.43) greater among medical cannabis users compared with non-medical users and 1.66 (95% CI, 1.27–2.16) greater among those reporting use for managing the comorbidities of pain, anxiety and depression. A slightly higher percentage of those who reported substituting resided in states where medical cannabis was legal at the time of the survey (47% vs. 45%, p=0.58), but this difference was not statistically significant. Discussion These patient-reported outcomes support prior research that individuals are using cannabis as a substitute for prescription drugs, particularly, narcotics/opioids, and independent of whether they identify themselves as medical or non-medical users. This is especially true if they suffer from pain, anxiety and depression. Additionally, this study suggests that state laws allowing access to, and use of, medical

Arrhythmogenic effects of illicit drugs in athletes.

Furlanello, Francesco; Bentivegna, Stefano; Cappato, Riccardo; De Ambroggi, Luigi

2003-12-01

Cardiac arrhythmias are among the most important causes of non-eligibility to sports activities, and may be due to different causes (cardiomyopathies, myocarditis, coronary abnormalities, valvular diseases, primary electrical disorders, abuse of illicit drugs). The list of illicit drugs banned by the International Olympic Committee and yearly updated by the World Anti-Doping Agency includes the following classes: stimulants, narcotics, anabolic agents (androgenic steroids and others such as beta-2 stimulants), peptide hormones, mimetics and analogues, diuretics, agents with an antiestrogenic activity, masking agents. Almost all illicit drugs may cause, through a direct or indirect arrhythmogenic effect, in the short, medium or long term, a wide range of cardiac arrhythmias (focal or reentry type, supraventricular and/or ventricular), lethal or not, even in healthy subjects with no previous history of cardiac diseases. Therefore, given the widespread abuse of illicit drugs among athletes, in the management of arrhythmic athletes the cardiologist should always take into consideration the possibility that the arrhythmias be due to the assumption of illicit drugs (sometimes more than one type), especially if no signs of cardiac diseases are present. On the other hand, in the presence of latent underlying arrhythmogenic heart disease including some inherited cardiomyopathies at risk of sudden cardiac death, illicit drugs could induce severe cardiac arrhythmic effects.

On October 5, 1981, Fortune magazine published a cover article entitled the "Next Industrial Revolution: Designing Drugs by Computer at Merck". With a 40+ year investment, we have been in the drug design business longer than most. During its history, the Merck drug design group has had several names, but it has always been in the "design" business, with the ultimate goal to provide an actionable hypothesis that could be tested experimentally. Often the result was a small molecule but it could just as easily be a peptide, biologic, predictive model, reaction, process, etc. To this end, the concept of design is now front and center in all aspects of discovery, safety assessment and early clinical development. At present, the Merck design group includes computational chemistry, protein structure determination, and cheminformatics. By bringing these groups together under one umbrella, we were able to align activities and capabilities across multiple research sites and departments. This alignment from 2010 to 2016 resulted in an 80% expansion in the size of the department, reflecting the increase in impact due to a significant emphasis across the organization to "design first" along the entire drug discovery path from lead identification (LID) to first in human (FIH) dosing. One of the major advantages of this alignment has been the ability to access all of the data and create an adaptive approach to the overall LID to FIH pathway for any modality, significantly increasing the quality of candidates and their probability of success. In this perspective, we will discuss how we crafted a new strategy, defined the appropriate phenotype for group members, developed the right skillsets, and identified metrics for success in order to drive continuous improvement. We will not focus on the tactical implementation, only giving specific examples as appropriate.

In this perspective, we will discuss how we crafted a new strategy, defined the appropriate phenotype for group members, developed the right skillsets, and identified metrics for success in order to drive continuous improvement. We will not focus on the tactical implementation, only giving specific examples as appropriate.

The design of drugs for HIV and HCV.

De Clercq, Erik

2007-12-01

Since the discovery of the human immunodeficiency virus (HIV) in 1983, dramatic progress has been made in the development of novel antiviral drugs. The HIV epidemic fuelled the development of new antiviral drug classes, which are now combined to provide highly active antiretroviral therapies. The need for the treatment of hepatitis C virus (HCV), which was discovered in 1989, has also provided considerable impetus for the development of new classes of antiviral drugs, and future treatment strategies for chronic HCV might involve combination regimens that are analogous to those currently used for HIV. By considering the drug targets in the different stages of the life cycle of these two viruses, this article presents aspects of the history, medicinal chemistry and mechanisms of action of approved and investigational drugs for HIV and HCV, and highlights general lessons learned from anti-HIV-drug design that could be applied to HCV.

Innovations: Alcohol & drug abuse: Narcotics on the net: the availability of Web sites selling controlled substances.

Forman, Robert F

2006-01-01

The Internet is not only a vital medium for communication, entertainment, and commerce, but it is also an outlet for illicit drug sales. Although the U.S. Controlled Substances Act regulates access to certain drugs by requiring prescriptions, unique characteristics of the Internet create significant challenges for the enforcement of U.S. drug policies. In the late 1990s "no prescription Web sites" (NPWs) began to emerge, which allow persons to purchase drugs, such as opiates, without a prescription. Given the likely role of NPWs in increasing prescription drug abuse, health care professionals must develop and disseminate strategies for helping patients who are affected by these Web sites.

Per-oral endoscopic myotomy (POEM) is a less invasive therapy for achalasia with a shorter hospitalization but with similar short- and long-term outcomes as a laparoscopic Heller myotomy (LHM). Previous literature comparing POEM to LHM has focused primarily on postoperative outcome parameters such as complications, dysphagia scores and gastro-esophageal reflux severity. This study specifically compares postoperative pain following POEM to pain following LHM, the current gold-standard operation. A retrospective review of all patients undergoing POEM or LHM for achalasia was performed from 2006 to 2015. Data collection included demographics, comorbidities, length of stay (LOS) and pain scores (arrival to the recovery room, 1 h postoperative, average first 24 h and upon discharge). Statistical analysis was performed using Student's t test and Chi-square test. Forty-four POEM patients and 122 LHM patients were identified. The average age (52.2 ± 20.75 vs 50.9 ± 17.89 years, p = 0.306) and BMI (28.1 ± 7.62 vs 27.6 ± 7.07 kg/m 2 , p = 0.824) did not differ between the POEM and LHM groups, respectively; however, the American Society of Anesthesiology scores were higher in the POEM patients (2.43 ± 0.62 vs 2.11 ± 0.71, p = 0.011). There were no differences in rates of smoking, diabetes, cardiac disease or pulmonary disease. The average pain scores upon arrival to the recovery room and 1 h postoperatively were lower in the POEM group (2.3 ± 3.014 vs 3.61 ± 3 0.418, p = 0.025 and 2.2 ± 2.579 vs 3.46 ± 3.063, p = 0.034, respectively). There was no difference in the average pain score over the first 24 h (2.7 ± 2.067 vs 3.29 ± 1.980, p = 0.472) or at the time of discharge (1.6 ± 2.420 vs 2.09 ± 2.157, p = 0.0657) between the POEM and LHM groups. After standardizing opioid administration against 10 mg of oral morphine, the POEM group used significantly less narcotics that the LHM group (35.8 vs 101.8 mg, p < 0

Hori, Hitoshi; Uto, Yoshihiro; Nakata, Eiji

2010-09-01

We describe herein for the first time our medicinal electronomics bricolage design of hypoxia-targeting antineoplastic drugs and boron tracedrugs as newly emerging drug classes. A new area of antineoplastic drugs and treatments has recently focused on neoplastic cells of the tumor environment/microenvironment involving accessory cells. This tumor hypoxic environment is now considered as a major factor that influences not only the response to antineoplastic therapies but also the potential for malignant progression and metastasis. We review our medicinal electronomics bricolage design of hypoxia-targeting drugs, antiangiogenic hypoxic cell radiosensitizers, sugar-hybrid hypoxic cell radiosensitizers, and hypoxia-targeting 10B delivery agents, in which we design drug candidates based on their electronic structures obtained by molecular orbital calculations, not based solely on pharmacophore development. These drugs include an antiangiogenic hypoxic cell radiosensitizer TX-2036, a sugar-hybrid hypoxic cell radiosensitizer TX-2244, new hypoxia-targeting indoleamine 2,3-dioxygenase (IDO) inhibitors, and a hypoxia-targeting BNCT agent, BSH (sodium borocaptate-10B)-hypoxic cytotoxin tirapazamine (TPZ) hybrid drug TX-2100. We then discuss the concept of boron tracedrugs as a new drug class having broad potential in many areas.

Computational methods for docking small molecules to proteins are prominent in drug discovery. There are hundreds, if not thousands, of documented examples-and several pertinent cases within our research program. Fifteen years ago, our first docking-guided drug design project yielded nanomolar metalloproteinase inhibitors and illustrated the potential of structure-based drug design. Subsequent applications of docking programs to the design of integrin antagonists, BACE-1 inhibitors, and aminoglycosides binding to bacterial RNA demonstrated that available docking programs needed significant improvement. At that time, docking programs primarily considered flexible ligands and rigid proteins. We demonstrated that accounting for protein flexibility, employing displaceable water molecules, and using ligand-based pharmacophores improved the docking accuracy of existing methods-enabling the design of bioactive molecules. The success prompted the development of our own program, Fitted, implementing all of these aspects. The primary motivation has always been to respond to the needs of drug design studies; the majority of the concepts behind the evolution of Fitted are rooted in medicinal chemistry projects and collaborations. Several examples follow: (1) Searching for HDAC inhibitors led us to develop methods considering drug-zinc coordination and its effect on the pKa of surrounding residues. (2) Targeting covalent prolyl oligopeptidase (POP) inhibitors prompted an update to Fitted to identify reactive groups and form bonds with a given residue (e.g., a catalytic residue) when the geometry allows it. Fitted-the first fully automated covalent docking program-was successfully applied to the discovery of four new classes of covalent POP inhibitors. As a result, efficient stereoselective syntheses of a few screening hits were prioritized rather than synthesizing large chemical libraries-yielding nanomolar inhibitors. (3) In order to study the metabolism of POP inhibitors by

Furlanello, Francesco; Serdoz, Laura Vitali; Cappato, Riccardo; De Ambroggi, Luigi

2007-08-01

The current management of athletes with cardiac arrhythmias has become complicated by the widespread use of illicit drugs, which can be arrhythmogenic. The World Anti-Doping Agency annually updates a list of prohibited substances and methods banned by the International Olympic Committee that includes different classes of substances namely, anabolic androgenic steroids, hormones and related substances, beta2-agonists, diuretics, stimulants, narcotics, cannabinoids, glucocorticosteroids, alcohol, beta-blockers and others. Almost all illicit drugs may cause, through a direct or indirect arrhythmogenic effect, a wide range of cardiac arrhythmias (focal or reentry type, supraventricular and/or ventricular) that can even be lethal and which are frequently sport activity related. A large use of illicit drugs has been documented in competitive athletes, but the arrhythmogenic effect of specific substances is not precisely known. Precipitation of cardiac arrhythmias, particularly in the presence of a latent electrophysiologic substrate including some inherited cardiomyopathies, at risk of sudden death or due to long-term consumption of the substances, should raise the suspicion that illicit drugs may be a possible cause and lead cardiologists to investigate carefully this relationship and appropriately prevent the clinical consequences.

Full Text Available 3D-structures of proteins and potential ligands are the cornerstones of rational drug design. The first brick to build upon is selecting a protein target and finding out whether biologically active compounds are known. Both tasks require more information than the structures themselves provide. For this purpose we have built a web resource bridging protein and ligand databases. It consists of three parts: i A data warehouse on annotation of protein structures that integrates many well-known databases such as Swiss-Prot, SCOP, ENZYME and others. ii A conformational library of structures of approved drugs. iii A conformational library of ligands from the PDB, linking the realms of proteins and small molecules.

For many years Malaysia faced the drug addiction issues. The most serious case is relapse phenomenon among treated drug addict (drug addict who have under gone the rehabilitation programme at Narcotic Addiction Rehabilitation Centre, PUSPEN). Thus, the main objective of this study is to find the most significant factor that contributes to relapse to happen. The binary logistic regression analysis was employed to model the relationship between independent variables (predictors) and dependent variable. The dependent variable is the status of the drug addict either relapse, (Yes coded as 1) or not, (No coded as 0). Meanwhile the predictors involved are age, age at first taking drug, family history, education level, family crisis, community support and self motivation. The total of the sample is 200 which the data are provided by AADK (National Antidrug Agency). The finding of the study revealed that age and self motivation are statistically significant towards the relapse cases..

Emerging data suggest that use and abuse of prescription drugs may be decreasing in states where medical cannabis is legal. The aim of this study was to survey cannabis users to determine whether they had intentionally substituted cannabis for prescription drugs.Methods: A total of 2,774 individuals were a self-selected convenience sample who reported having used cannabis at least once in the previous 90 days. Subjects were surveyed via an online anonymous questionnaire on cannabis substitution effects. Participants were recruited through social media and cannabis dispensaries in Washington State.Results: A total of 1,248 (46% respondents reported using cannabis as a substitute for prescription drugs. The most common classes of drugs substituted were narcotics/opioids (35.8%, anxiolytics/benzodiazepines (13.6% and antidepressants (12.7%. A total of 2,473 substitutions were reported or approximately two drug substitutions per affirmative respondent. The odds of reporting substituting were 4.59 (95% confidence interval [CI], 3.87–5.43 greater among medical cannabis users compared with non-medical users and 1.66 (95% CI, 1.27–2.16 greater among those reporting use for managing the comorbidities of pain, anxiety and depression. A slightly higher percentage of those who reported substituting resided in states where medical cannabis was legal at the time of the survey (47% vs. 45%, p=0.58, but this difference was not statistically significant.Discussion: These patient-reported outcomes support prior research that individuals are using cannabis as a substitute for prescription drugs

Tamper-resistant prescription forms for narcotics in France:should we generalise them?

In France, prescription of narcotics must be written on a tamper-resistant prescription form with specific technical particularities. Dosage and daily dose of medicines shall be written out entirely in letters. These prescription forms are also mandatory for buprenorphine, clorazepate, clonazepam, tianeptine, buccal midazolam and zolpidem owing to traffic, abuse or diversion. In 2012, to assess the use of standard and tamper-resistant prescription forms and the acceptability of the generalization of the latter to all medicines, a national opinion survey was performed, with a postal questionnaire, within 3 randomized samples of 1,500 prescribers (physicians, dentists and midwives). Of the 403 participating prescribers (participation rate of 26.8%), 373 were physicians, 14 dentists and 16 midwives. Tamper-resistant prescription forms were used by 76.2% of prescribers, but only by 5.1% in a computerised version, whereas, for standard prescription forms, 61% used computer assisted prescription software. The main reason was the inability of the prescription software to print these forms or to respect the mandatory prescription rules for narcotics. Theft and falsification of prescriptions had ever occurred (working life). Most prescribers (62.5%) were against the generalization of tamper-resistant prescription forms. Those in favour were for a generalization to all medicines (65%) and not only to psychotropic agents. Generalization of tamper-resistant prescription forms is not a consensual solution to prevent medicines' diversion. Some prescribers alluded to the possibility of dematerialisation and electronic transmission of prescription forms, which could avoid theft, forgery or falsification.

Application of Absorption Modeling in Rational Design of Drug Product Under Quality-by-Design Paradigm.

Science.gov (United States)

Kesisoglou, Filippos; Mitra, Amitava

2015-09-01

Physiologically based absorption models can be an important tool in understanding product performance and hence implementation of Quality by Design (QbD) in drug product development. In this report, we show several case studies to demonstrate the potential application of absorption modeling in rational design of drug product under the QbD paradigm. The examples include application of absorption modeling—(1) prior to first-in-human studies to guide development of a formulation with minimal sensitivity to higher gastric pH and hence reduced interaction when co-administered with PPIs and/or H2RAs, (2) design of a controlled release formulation with optimal release rate to meet trough plasma concentrations and enable QD dosing, (3) understanding the impact of API particle size distribution on tablet bioavailability and guide formulation design in late-stage development, (4) assess impact of API phase change on product performance to guide specification setting, and (5) investigate the effect of dissolution rate changes on formulation bioperformance and enable appropriate specification setting. These case studies are meant to highlight the utility of physiologically based absorption modeling in gaining a thorough understanding of the product performance and the critical factors impacting performance to drive design of a robust drug product that would deliver the optimal benefit to the patients.

Design optimization of a novel pMDI actuator for systemic drug delivery.

Pressurized metered dose inhalers (pMDIs) are the most widely prescribed and economical respiratory drug delivery systems. Conventional pMDI actuators-those based on "two-orifice-and-sump" designs-produce an aerosol with a reasonable respirable fraction, but with high aerosol velocity. The latter is responsible for high oropharyngeal deposition, and consequently low drug delivery efficiency. Kos' pMDI technology is based on a proprietary vortex nozzle actuator (VNA), an innovative actuator configuration that seeks to reduce aerosol plume velocity, thereby promoting deep lung deposition. Using VNA development as a case study, this paper presents a systematic design optimization process to improve the actuator performance through use of advanced optical characterization tools. The optimization effort mainly relied on laser-based optical diagnostics to provide an improved understanding of the fundamentals of aerosol formation and interplay of various geometrical factors. The performance of the optimized VNA design thus evolved was characterized using phase Doppler anemometry and cascade impaction. The aerosol velocities for both standard and optimized VNA designs were found to be comparable, with both notably less than conventional actuators. The optimized VNA design also significantly reduces drug deposition in the actuator as well as USP throat adapter, which in turn, leads to a significantly higher fine particle fraction than the standard design (78 +/- 3% vs. 63 +/- 2% on an ex valve basis). This improved drug delivery efficiency makes VNA technology a practical proposition as a systemic drug delivery platform. Thus, this paper demonstrates how advanced optical diagnostic and characterization tools can be used in the development of high efficiency aerosol drug delivery devices.

Multi-Step Usage of in Vivo Models During Rational Drug Design and Discovery

Directory of Open Access Journals (Sweden)

Charles H. Williams

2011-04-01

Full Text Available In this article we propose a systematic development method for rational drug design while reviewing paradigms in industry, emerging techniques and technologies in the field. Although the process of drug development today has been accelerated by emergence of computational methodologies, it is a herculean challenge requiring exorbitant resources; and often fails to yield clinically viable results. The current paradigm of target based drug design is often misguided and tends to yield compounds that have poor absorption, distribution, metabolism, and excretion, toxicology (ADMET properties. Therefore, an in vivo organism based approach allowing for a multidisciplinary inquiry into potent and selective molecules is an excellent place to begin rational drug design. We will review how organisms like the zebrafish and Caenorhabditis elegans can not only be starting points, but can be used at various steps of the drug development process from target identification to pre-clinical trial models. This systems biology based approach paired with the power of computational biology; genetics and developmental biology provide a methodological framework to avoid the pitfalls of traditional target based drug design.

Legalization of drugs of abuse and the pediatrician.

Science.gov (United States)

Schwartz, R H

1991-10-01

Growing numbers of individuals are proposing that drugs be legalized in the United States, with claims that federal, state, and local efforts to prohibit the use of illicit drugs are irrational and unenforceable. "Drug reform" advocates include persons of all political persuasions. Ironically, the call for drug reform comes at a time when trends in drug abuse, as reflected in national and state surveys, show a promising decline. It also is contradictory to at least one recent public opinion poll, in which respondents opposed the legalization of marijuana by a five-to-one margin. While their position is by no means unanimous, proponents of drug reform generally base their arguments on several key premises, such as elimination of or reductions in drug trafficking, enforcement, and interdiction expenditures; increased tax revenues from the legal sale of drugs; and reductions in health-care expenses associated with drug treatment. Reform advocates further claim that legalization would not be followed by an increase in drug use. The validity of each of these arguments is highly questionable. Legalization is a simplistic, short-sighted solution to a complex issue with public health, economic, criminal justice, and societal ramifications. Legalization would, moreover, abrogate the position taken in 1961 by the United States and 114 other nations in ratifying the United Nations Single Convention on Narcotic Drugs. The impact of drug reform merits an unbiased study by an independent agency. Until that time, pediatricians should inform themselves of the arguments for and against drug reform and be prepared to educate patients and their families about the issue.

[Drug Addiction Self-Help Recovery scale (DASH-scale): an approach to the measurement of recovery from drug addiction in self-help program among drug addicts].

Shimane, Takuya; Misago, Chizuru

2004-12-01

The purpose of the study was to develop a scale for measuring the recovery in self-help program for drug addicts. Our study sites were fourteen self-help groups for drug addicts called "DARC: Drug Addiction Rehabilitation Center". DARC activities were based on Narcotics Anonymous types of self-help program. The 25-items DASH-scale questionnaire was developed using data, which were obtained through in-depth interview among DARC staff. A cross-sectional study among recovering addicts participating in "DARC" activities was implemented from Jan 2004 to Feb 2004. 164 subjects were responded to our questionnaire. Factor analysis was carried out and items with weaker or split loadings were removed. Factor analysis of DASH-scale results produced a surprisingly clean four-factor solution. 19-items were left to form the final DASH-scale; regular life-style (6 items), acceptance of drug addiction (5 items), sympathy with member (5 items), reborn (3 items). The internal consistency (Cronbach's Alpha) of these scales was very high (0.87). Low but significant concurrent correlations were observed between the DASH-scale and the Rosenberg Self-Esteem Scale (0.22), Purpose in Life Test (0.35). Discriminant validity of the DASH-scale was supported by significant increase with exposed period of self-help program. Evidence supports the DASH-scale was possible to measure recovery in self-help program.

Drug suicide: a sex-equal cause of death in 16 European countries

Abstract Background There is a lack of international research on suicide by drug overdose as a preventable suicide method. Sex- and age-specific rates of suicide by drug self-poisoning (ICD-10, X60-64) and the distribution of drug types used in 16 European countries were studied, and compared with other self-poisoning methods (X65-69) and intentional self-injury (X70-84). Methods Data for 2000-04\\/05 were collected from national statistical offices. Age-adjusted suicide rates, and age and sex distributions, were calculated. Results No pronounced sex differences in drug self-poisoning rates were found, either in the aggregate data (males 1.6 and females 1.5 per 100,000) or within individual countries. Among the 16 countries, the range (from some 0.3 in Portugal to 5.0 in Finland) was wide. \\'Other and unspecified drugs\\' (X64) were recorded most frequently, with a range of 0.2-1.9, and accounted for more than 70% of deaths by drug overdose in France, Luxembourg, Portugal and Spain. Psychotropic drugs (X61) ranked second. The X63 category (\\'other drugs acting on the autonomic nervous system\\') was least frequently used. Finland showed low X64 and high X61 figures, Scotland had high levels of X62 (\\'narcotics and hallucinogens, not elsewhere classified\\') for both sexes, while England exceeded other countries in category X60. Risk was highest among the middle-aged everywhere except in Switzerland, where the elderly were most at risk. Conclusions Suicide by drug overdose is preventable. Intentional self-poisoning with drugs kills as many males as females. The considerable differences in patterns of self-poisoning found in the various European countries are relevant to national efforts to improve diagnostics of suicide and appropriate specific prevention. The fact that vast majority of drug-overdose suicides came under the category X64 refers to the need of more detailed ICD coding system for overdose suicides is needed to permit better design of suicide

Computer-Aided Drug Design Applied to Marine Drug Discovery: Meridianins as Alzheimer's Disease Therapeutic Agents.

Llorach-Pares, Laura; Nonell-Canals, Alfons; Sanchez-Martinez, Melchor; Avila, Conxita

2017-11-27

Computer-aided drug discovery/design (CADD) techniques allow the identification of natural products that are capable of modulating protein functions in pathogenesis-related pathways, constituting one of the most promising lines followed in drug discovery. In this paper, we computationally evaluated and reported the inhibitory activity found in meridianins A-G, a group of marine indole alkaloids isolated from the marine tunicate Aplidium , against various protein kinases involved in Alzheimer's disease (AD), a neurodegenerative pathology characterized by the presence of neurofibrillary tangles (NFT). Balance splitting between tau kinase and phosphate activities caused tau hyperphosphorylation and, thereby, its aggregation and NTF formation. Inhibition of specific kinases involved in its phosphorylation pathway could be one of the key strategies to reverse tau hyperphosphorylation and would represent an approach to develop drugs to palliate AD symptoms. Meridianins bind to the adenosine triphosphate (ATP) binding site of certain protein kinases, acting as ATP competitive inhibitors. These compounds show very promising scaffolds to design new drugs against AD, which could act over tau protein kinases Glycogen synthetase kinase-3 Beta (GSK3β) and Casein kinase 1 delta (CK1δ, CK1D or KC1D), and dual specificity kinases as dual specificity tyrosine phosphorylation regulated kinase 1 (DYRK1A) and cdc2-like kinases (CLK1). This work is aimed to highlight the role of CADD techniques in marine drug discovery and to provide precise information regarding the binding mode and strength of meridianins against several protein kinases that could help in the future development of anti-AD drugs.

Designing multi-targeted agents: An emerging anticancer drug discovery paradigm.

Science.gov (United States)

Fu, Rong-Geng; Sun, Yuan; Sheng, Wen-Bing; Liao, Duan-Fang

2017-08-18

The dominant paradigm in drug discovery is to design ligands with maximum selectivity to act on individual drug targets. With the target-based approach, many new chemical entities have been discovered, developed, and further approved as drugs. However, there are a large number of complex diseases such as cancer that cannot be effectively treated or cured only with one medicine to modulate the biological function of a single target. As simultaneous intervention of two (or multiple) cancer progression relevant targets has shown improved therapeutic efficacy, the innovation of multi-targeted drugs has become a promising and prevailing research topic and numerous multi-targeted anticancer agents are currently at various developmental stages. However, most multi-pharmacophore scaffolds are usually discovered by serendipity or screening, while rational design by combining existing pharmacophore scaffolds remains an enormous challenge. In this review, four types of multi-pharmacophore modes are discussed, and the examples from literature will be used to introduce attractive lead compounds with the capability of simultaneously interfering with different enzyme or signaling pathway of cancer progression, which will reveal the trends and insights to help the design of the next generation multi-targeted anticancer agents.

Van Vrancken, Michael J; Benavides, Raul; Wians, Frank H

2013-01-01

In recent years, access to information regarding acquisition and synthesis of newer designer drugs has been at an all-time high due largely to the Internet. As these drugs have become more prevalent, laboratory techniques have been developed and refined to identify and screen for this burgeoning population of drugs. This provides a unique opportunity for learning about many of these methods. Laboratory testing techniques and instrumentation are obscure to many health care professionals, yet their results are crucial. Here, we present a case of an overdose of an uncommon designer drug (2C-E) and discuss the basics of liquid chromatography and mass spectrometry, two important techniques used in isolating and identifying the drug. Although often overlooked and taken for granted, these techniques can play a pivotal role in the diagnosis and subsequent management of select patients.

Although there were many discussion and debate by human rights activists on the death penalty which is a violation of human rights, but it does not impede our law enforcement officials to carry out executions, considering death penalty is a part of law as stipulated in article 10 of the Criminal Code. By giving death penalty to the perpetrators of criminal drugs acts, then its expected to eradicate narcotics in Indonesia, considering that imprisonment is no longer effectively applied and provides an opportunity for the convict to become recidivists or even control the narcotics selling inside the prisons such as alleged cases conducted by Freddy Budiman.

Methods: In this cross-sectional study a self-defined and validated questionnaire was used which included all the necessary and standard needed spaces and equipments of an ideal hospital pharmacy. The questionnaire was filled in by one of the researchers in all twelve hospital drugstores located in the teaching and non-teaching hospitals affiliated with Isfahan University of Medical Sciences. Data analysis was done using SPSS (version 14. Results: Results showed that 56% of drugstore space allocations were unsuitable. Used pharmaceutical equipments in 75% of surveyed hospitals were not according to the standards. Almost all of these pharmacies had rather an enough space for storage, but cold storages were not designed in 58% of them. In 66% of perused hospitals, pharmaceutical services disposal level was admissible. The structural engineering parameters like size and dimensions, available spaces, availability of structural planes, existence of air conditioning systems and brightness controllers, adequate stores for drugs and safe places for narcotics were observed in 55% of pharmacies. Conclusions: There are apparent out of standard space allocations and shortages of needed equipments for offering drug services in studied drugstores that may probably lead to a waste of time and money. These issues may reduce the efficiency and safety of pharmaceutical services and drug administration in hospitals.

Reviews of the development of drug discovery through the 20(th) century recognised the importance of chemistry and increasingly bioinformatics, but had relatively little to say about the importance of computing and networked computing in particular. However, the design and discovery of new drugs is arguably the most significant single application of bioinformatics and cheminformatics to have benefitted from the increases in the range and power of the computational techniques since the emergence of the World Wide Web, commonly now referred to as simply 'the Web'. Web services have enabled researchers to access shared resources and to deploy standardized calculations in their search for new drugs. This article first considers the fundamental principles of Web services and workflows, and then explores the facilities and resources that have evolved to meet the specific needs of chem- and bio-informatics. This strategy leads to a more detailed examination of the basic components that characterise molecules and the essential predictive techniques, followed by a discussion of the emerging networked services that transcend the basic provisions, and the growing trend towards embracing modern techniques, in particular the Semantic Web. In the opinion of the authors, the issues that require community action are: increasing the amount of chemical data available for open access; validating the data as provided; and developing more efficient links between the worlds of cheminformatics and bioinformatics. The goal is to create ever better drug design services.

Cholesterol is a well-known component in fats of animal origin and it also is the precursor of natural hormones. Phytosterols appear in plants and only differ slightly in structure from cholesterol. An important difference however is the low absorption in the gut of phytosterols and their saturated derivatives, the phytostanols. As a result, there is time for all kind of reactions in faecal material inside and outside of the gut. Determination of the abuse of natural hormones may be based on gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS). Abuse of natural hormones changes the {sup 13}C/{sup 12}C ratio of some metabolites during a relatively long time. The formation of (natural) hormones in the gut may interfere with this method. Designer drugs are mainly known from sports doping. In animal fattening, designer drugs may be used as well. Small changes in the structure of (natural) hormones may lead to a new group of substances asking for new strategies for their detection and the constatation of their abuse.

2017-01-01

The pharmaceutical industry is progressively operating in an era where development costs are constantly under pressure, higher percentages of drugs are demanded, and the drug-discovery process is a trial-and-error run. The profit that flows in with the discovery of new drugs has always been the motivation for the industry to keep up the pace and keep abreast with the endless demand for medicines. The process of finding a molecule that binds to the target protein using in silico tools has made computational chemistry a valuable tool in drug discovery in both academic research and pharmaceutical industry. However, the complexity of many protein-ligand interactions challenges the accuracy and efficiency of the commonly used empirical methods. The usefulness of quantum mechanics (QM) in drug-protein interaction cannot be overemphasized; however, this approach has little significance in some empirical methods. In this review, we discuss recent developments in, and application of, QM to medically relevant biomolecules. We critically discuss the different types of QM-based methods and their proposed application to incorporating them into drug-design and -discovery workflows while trying to answer a critical question: are QM-based methods of real help in drug-design and -discovery research and industry?

Drug design and discovery is an innovation process that translates the outcomes of fundamental biomedical research into therapeutics that are ultimately made available to people with medical disorders in many countries throughout the world. To identify which nations succeed, exceed, or fail at the drug design/discovery endeavor--more specifically, which countries, within the context of their national size and wealth, are "pulling their weight" when it comes to developing medications targeting the myriad of diseases that afflict humankind--we compiled and analyzed a comprehensive survey of all new drugs (small molecular entities and biologics) approved annually throughout the world over the 20-year period from 1991 to 2010. Based upon this analysis, we have devised prediction algorithms to ascertain which countries are successful (or not) in contributing to the worldwide need for effective new therapeutics. © 2013 Wiley Periodicals, Inc.

Design of a tripartite network for the prediction of drug targets

Science.gov (United States)

Kunimoto, Ryo; Bajorath, Jürgen

2018-02-01

Drug-target networks have aided in many target prediction studies aiming at drug repurposing or the analysis of side effects. Conventional drug-target networks are bipartite. They contain two different types of nodes representing drugs and targets, respectively, and edges indicating pairwise drug-target interactions. In this work, we introduce a tripartite network consisting of drugs, other bioactive compounds, and targets from different sources. On the basis of analog relationships captured in the network and so-called neighbor targets of drugs, new drug targets can be inferred. The tripartite network was found to have a stable structure and simulated network growth was accompanied by a steady increase in assortativity, reflecting increasing correlation between degrees of connected nodes leading to even network connectivity. Local drug environments in the tripartite network typically contained neighbor targets and revealed interesting drug-compound-target relationships for further analysis. Candidate targets were prioritized. The tripartite network design extends standard drug-target networks and provides additional opportunities for drug target prediction.

Deren, S; Des Jarlais, D C

1977-01-01

The utility of the shift-to-risk design for studying the influence of peer groups on drug taking was investigated. Two studies using this design with drug content were conducted, varying the level of information provided about a drug. Subjects were from two college classes consisting of 26 and 28 students. Results indicated that the specification of possible harmful drug effects which are somewhat minimal lead to a significantly greater willingness to recommend trying the drug. In addition, a tendency for a shift-to-caution was found. It was concluded that the shift-to-risk designwas useful for studying decision-making regarding drug use, and that both users and nonusers of drugs should be included in future research.

In this overview, we highlight three aspects of the use of molecular docking. First, we discuss the combination of molecular and quantum mechanics to investigate an unusual enzymatic mechanism of a flavoprotein. Second, we present recent advances in anti-infectious agents' synthesis driven by structural insights. At the end, we focus on larger biological complexes made by protein–protein interactions and discuss their relevance in drug design. This review provides information on how these large systems, even in the presence of the solvent, can be investigated with the outlook of drug discovery.Keywords: structure-based drug design, protein–protein docking, quaternary structure prediction, residue interaction networks, RINs, water position

The aim of this work is to present a simple, practical and efficient protocol for drug design, in particular Diabetes, which includes selection of the illness, good choice of a target as well as a bioactive ligand and then usage of various computer aided drug design and medicinal chemistry tools to design novel potential drug candidates in different diseases. We have selected the validated target dipeptidyl peptidase IV (DPP-IV), whose inhibition contributes to reduce glucose levels in type 2 diabetes patients. The most active inhibitor with complex X-ray structure reported was initially extracted from the BindingDB database. By using molecular modification strategies widely used in medicinal chemistry, besides current state-of-the-art tools in drug design (including flexible docking, virtual screening, molecular interaction fields, molecular dynamics, ADME and toxicity predictions), we have proposed 4 novel potential DPP-IV inhibitors with drug properties for Diabetes control, which have been supported and validated by all the computational tools used herewith.

Taking aim at a moving target: designing drugs to inhibit drug-resistant HIV-1 reverse transcriptases.

HIV undergoes rapid genetic variation; this variation is caused primarily by the enormous number of viruses produced daily in an infected individual. Because of this variation, HIV presents a moving target for drug and vaccine development. The variation within individuals has led to the generation of diverse HIV-1 subtypes, which further complicates the development of effective drugs and vaccines. In general, it is more difficult to hit a moving target than a stationary target. Two broad strategies for hitting a moving target (in this case, HIV replication) are to understand the movement and to aim at the portions that move the least. In the case of anti-HIV drug development, the first option can be addressed by understanding the mechanism(s) of drug resistance and developing drugs that effectively inhibit mutant viruses. The second can be addressed by designing drugs that interact with portions of the viral machinery that are evolutionarily conserved, such as enzyme active sites.

2005-10-01

In the post-genome-sequencing era, emerging genomic technologies are shifting the paradigm for drug discovery and development. Nevertheless, drug discovery and development still remain high-risk and high-stakes ventures with long and costly timelines. Indeed, the attrition of drug candidates in preclinical and development stages is a major problem in drug design. For at least 30% of the candidates, this attrition is due to poor pharmacokinetics and toxicity. Thus, pharmaceutical companies have begun to seriously re-evaluate their current strategies of drug discovery and development. In that light, we propose that a transport mechanism-based design might help to create new, pharmacokinetically advantageous drugs, and as such should be considered an important component of drug design strategy. Performing enzyme- and/or cell-based drug transporter, interaction tests may greatly facilitate drug development and allow the prediction of drug-drug interactions. We recently developed methods for high-speed functional screening and quantitative structure-activity relationship analysis to study the substrate specificity of ABC transporters and to evaluate the effect of genetic polymorphisms on their function. These methods would provide a practical tool to screen synthetic and natural compounds, and these data can be applied to the molecular design of new drugs. In this review article, we present an overview on the genetic polymorphisms of human ABC transporter ABCG2 and new camptothecin analogues that can circumvent AGCG2-associated multidrug resistance of cancer.

Our understanding of the structural biology of G protein-coupled receptors has undergone a transformation over the past 5 years. New protein-ligand complexes are described almost monthly in high profile journals. Appreciation of how small molecules and natural ligands bind to their receptors has the potential to impact enormously how medicinal chemists approach this major class of receptor targets. An outline of the key topics in this field and some recent examples of structure- and fragment-based drug design are described. A table is presented with example views of each G protein-coupled receptor for which there is a published X-ray structure, including interactions with small molecule antagonists, partial and full agonists.

Kesharwani, Rajesh Kumar; Singh, Durg Vijay; Misra, Krishna

Cysteine proteases (falcipains), a papain-family of enzymes of Plasmodium falciparum, are responsible for haemoglobin degradation and thus necessary for its survival during asexual life cycle phase inside the human red blood cells while remaining non-functional for the human body. Therefore, these can act as potential targets for designing antimalarial drugs. The P. falciparum cysteine proteases, falcipain-II and falcipain- III are the enzymes which initiate the haemoglobin degradation, therefore, have been selected as targets. In the present study, we have designed new leupeptin analogues and subjected to virtual screening using Glide at the active site cavity of falcipain-II and falcipain-III to select the best docked analogues on the basis of Glide score and also compare with the result of AutoDock. The proposed analogues can be synthesized and tested in vivo as future potent antimalarial drugs. Protein falcipain-II and falcipain-III together with bounds inhibitors epoxysuccinate E64 (E64) and leupeptin respectively were retrieved from protein data bank (PDB) and latter leupeptin was used as lead molecule to design new analogues by using Ligbuilder software and refined the molecules on the basis of Lipinski rule of five and fitness score parameters. All the designed leupeptin analogues were screened via docking simulation at the active site cavity of falcipain-II and falcipain-III by using Glide software and AutoDock. The 104 new leupeptin-based antimalarial ligands were designed using structure-based drug designing approach with the help of Ligbuilder and subjected for virtual screening via docking simulation method against falcipain-II and falcipain-III receptor proteins. The Glide docking results suggest that the ligands namely result_037 shows good binding and other two, result_044 and result_042 show nearly similar binding than naturally occurring PDB bound ligand E64 against falcipain-II and in case of falcipain-III, 15 designed leupeptin analogues having

Design of Drug Delivery Methods for the Brain and Central Nervous System

Science.gov (United States)

Lueshen, Eric

Due to the impermeability of the blood-brain barrier (BBB) to macromolecules delivered systemically, drug delivery to the brain and central nervous system (CNS) is quite difficult and has become an area of intense research. Techniques such as convection-enhanced intraparenchymal delivery and intrathecal magnetic drug targeting offer a means of circumventing the blood-brain barrier for targeted delivery of therapeutics. This dissertation focuses on three aspects of drug delivery: pharmacokinetics, convection-enhanced delivery, and intrathecal magnetic drug targeting. Classical pharmacokinetics mainly uses black-box curve fitting techniques without biochemical or biological basis. This dissertation advances the state-of-the-art of pharmacokinetics and pharmacodynamics by incorporating first principles and biochemical/biotransport mechanisms in the prediction of drug fate in vivo. A whole body physiologically-based pharmacokinetics (PBPK) modeling framework is engineered which creates multiscale mathematical models for entire organisms composed of organs, tissues, and a detailed vasculature network to predict drug bioaccumulation and to rigorously determine kinetic parameters. These models can be specialized to account for species, weight, gender, age, and pathology. Systematic individual therapy design using the proposed mechanistic PBPK modeling framework is also a possibility. Biochemical, anatomical, and physiological scaling laws are also developed to accurately project drug kinetics in humans from small animal experiments. Our promising results demonstrate that the whole-body mechanistic PBPK modeling approach not only elucidates drug mechanisms from a biochemical standpoint, but offers better scaling precision. Better models can substantially accelerate the introduction of drug leads to clinical trials and eventually to the market by offering more understanding of the drug mechanisms, aiding in therapy design, and serving as an accurate dosing tool.

2013-06-01

Full Text Available This article assesses the use of capital punishment for drug trafficking and related crimes from a comparative perspective. Domestic narcotics legislation, as well as important drug trafficking cases in four Southeast Asian nations (Singapore, Malaysia, Indonesia, and Thailand are examined in-depth and compared to the United States, which plays an important role in eradicating global drug-related problems. This article contends that the use of capital punishment is disproportionate to the gravity of drug-related offenses and that international drug control and enforcement treaties never suggested using such sanctions to deter crime. Fortunately, four Southeast Asian countries in this study, including Singapore, Malaysia, Indonesia and Thailand, currently realize this disproportionality and have become reluctant to carry out executions for drug trafficking; even though they continue to sentence a large number of drug-related offenders to death annually, they do not actually carry out these executions. Future research related to this topic is also recommended in this article.

Drug Partitioning in Micellar Media and Its Implications in Rational Drug Design: Insights with Streptomycin.

Science.gov (United States)

Judy, Eva; Pagariya, Darshna; Kishore, Nand

2018-03-20

Oral bioavailability of a drug molecule requires its effective delivery to the target site. In general, majority of synthetically developed molecular entities have high hydrophobic nature as well as low bioavailability, therefore the need for suitable delivery vehicles arises. Self-assembled structures such as micelles, niosomes, and liposomes have been used as effective delivery vehicles and studied extensively. However, the information available in literature is mostly qualitative in nature. We have quantitatively investigated the partitioning of antibiotic drug streptomycin into cationic, nonionic, and a mixture of cationic and nonionic surfactant micelles and its interaction with the transport protein serum albumin upon subsequent delivery. A combination of calorimetry and spectroscopy has been used to obtain the thermodynamic signatures associated with partitioning and interaction with the protein and the resulting conformational changes in the latter. The results have been correlated with other class of drugs of different nature to understand the role of molecular features in the partitioning process. These studies are oriented toward understanding the physical chemistry of partitioning of a variety of drug molecules into suitable delivery vehicles and hence establishing structure-property-energetics relationships. Such studies provide general guidelines toward a broader goal of rational drug design.

Cohn, L.; Machado, Antonio F.; Bier, Robert; Cohn, Marthe

1988-01-01

To provide an effective continuum of the relief of severe carcinomatous pain with minimal side reactions, we initiated treatment with piroxicam (60 to 120 mg per day) and doxepin hydrochloride (25 to 225 mg per day). Of 30 patients presenting with severe pain of cancer of various origins, 7 continued to death with piroxicam and doxepin therapy. An additional 17 were successfully treated for 6 to 66 weeks with therapy reported here but, as disease progressed, required supplemental narcotics. The remaining six abandoned the use of piroxicam due to complications of therapy, which ranged from diarrhea to gastric perforation; serious complications were associated with patients' failure to adhere to a prescribed regimen of sucralfate. Therapy with piroxicam and doxepin proved to be safe and efficacious. PMID:3363962

Modern Prodrug Design for Targeted Oral Drug Delivery

Directory of Open Access Journals (Sweden)

Arik Dahan

2014-10-01

Full Text Available The molecular information that became available over the past two decades significantly influenced the field of drug design and delivery at large, and the prodrug approach in particular. While the traditional prodrug approach was aimed at altering various physiochemical parameters, e.g., lipophilicity and charge state, the modern approach to prodrug design considers molecular/cellular factors, e.g., membrane influx/efflux transporters and cellular protein expression and distribution. This novel targeted-prodrug approach is aimed to exploit carrier-mediated transport for enhanced intestinal permeability, as well as specific enzymes to promote activation of the prodrug and liberation of the free parent drug. The purpose of this article is to provide a concise overview of this modern prodrug approach, with useful successful examples for its utilization. In the past the prodrug approach used to be viewed as a last option strategy, after all other possible solutions were exhausted; nowadays this is no longer the case, and in fact, the prodrug approach should be considered already in the very earliest development stages. Indeed, the prodrug approach becomes more and more popular and successful. A mechanistic prodrug design that aims to allow intestinal permeability by specific transporters, as well as activation by specific enzymes, may greatly improve the prodrug efficiency, and allow for novel oral treatment options.

In recent years, access to information regarding acquisition and synthesis of newer designer drugs has been at an all-time high due largely to the Internet. As these drugs have become more prevalent, laboratory techniques have been developed and refined to identify and screen for this burgeoning population of drugs. This provides a unique opportunity for learning about many of these methods. Laboratory testing techniques and instrumentation are obscure to many health care professionals, yet t...

In this study, we developed a microdevice concept for drug/fluidic transport taking an inspiration from supramolecular motor found in biological cells. Specifically, idealized multi-functional design geometry (nozzle/diffuser/nozzle) was developed for (i) fluidic/particle transport; (ii) particle separation; and (iii) droplet generation. Several design simulations were conducted to demonstrate the working principles of the multi-functional device. The design simulations illustrate that the proposed design concept is feasible for multi-functionality. However, further experimentation and optimization studies are needed to fully evaluate the multifunctional device concept for multiple applications.

Cranial ultrasound examinations were performed during the first 3 days of life and at age 1 month on 22 infants with the neonatal abstinence syndrome. The results were compared to those obtained in 15 control infants who were not exposed to narcotic drugs in utero. The ultrasound images were examined for ventricular configuration, intracranial hemidiameters, area of thalami, and width of temporal lobes. At 24 to 72 h and at 1 month of age, significantly more drug-exposed than control infants had a slit-like ventricular configuration. The intracranial hemidiameter was significantly smaller in the drug-exposed than in the control infants. All cerebral measurements except the right temporal lobe demonstrated significant growth over the first month of life in both groups of infants. By means of ancillary examinations (computerized tomography and transfontanel pressure measurements) the pathogenesis of the slit-like ventricles was found not to be related to edema or to increased intracranial pressure. Whether or not the ventricles remain small and brain growth remains parallel after the period of abstinence awaits further investigation. (orig.)

The microbial and chemical analysis of illicit drug samples from different areas of Pakistan i.e. Quetta, Karachi, Lahore and Islamabad was conducted in a cross-sectional study at National Institute of Health, Islamabad. The drug samples were confiscated by Anti Narcotics Force (ANF), Pakistan. Microbial analysis was done by estimating bioburden which revealed the presence of gram negative and positive bacteria's, fungus, Streptococcus, Staphylococcus species. Trypton soya agar was used for total aerobic count, MacConkey agar for gram-negative bacteria, Sabouraud dextrose agar for fungus and Vogel-Johnson agar for Streptococcus and Staphylococcus species. Colour tests were applied to identify the drug samples. Qualitative and quantitative analysis of suspected samples of Heroin, morphine, cocaine and acetic anhydride was made by employing different chromatographic techniques i.e. Thin-layer chromatography (TLC) and High-performance liquid chromatography (HPLC). The samples were found to be adulterated with paracetamol, diazepam and Dextromethorphen. Acetic anhydride was adulterated with hydrochloric acid (HCl). There is lack of information providing structured advice on responses to the consequences of illicit drug adulteration. Robust and rehearsed interventions and communication strategies would provide a basis for response for a wide variety of organisations. Research into the usefulness of media warnings about adulteration of illicit drugs is required.

Full Text Available according to the authors, appeared not long ago new psychoactive substances (designer drugs, including synthetic cannabinoids, derivatives of cathinone, phenethylamines, new stimulants, synthetic opioids, tryptamine derivatives, phencyclidine, piperazine, agonists of GABA (A/B receptors have become a serious problem for both consumers and doctors. Consumers of these substances are attracted primarily by the intensity of psychoactive effects, as well as «legal purity», which is declared by shadow producers. This indicates that there are some significant difficulties of laboratory typing of new surfactants. Designer drugs when ingested, can affect a range of neurotransmitter pathways/receptors: dopamine, cannabinoid (CB1, GABA(A/B, 5-HT2A, glutamate, and k-opioid receptors (KOR, the imbalance of which leads to the development of polymorphic psychotic disorders.

Optimization and design of ibuprofen-loaded nanostructured lipid carriers using a hybrid-design approach for ocular drug delivery

Science.gov (United States)

Rathod, Vishal

The objective of the present project was to develop the Ibuprofen-loaded Nanostructured Lipid Carrier (IBU-NLCs) for topical ocular delivery based on substantial pre-formulation screening of the components and understanding the interplay between the formulation and process variables. The BCS Class II drug: Ibuprofen was selected as the model drug for the current study. IBU-NLCs were prepared by melt emulsification and ultrasonication technique. Extensive pre-formulation studies were performed to screen the lipid components (solid and liquid) based on drug's solubility and affinity as well as components compatibility. The results from DSC & XRD assisted in selecting the most suitable ratio to be utilized for future studies. DynasanRTM 114 was selected as the solid lipid & MiglyolRTM 840 was selected as the liquid lipid based on preliminary lipid screening. The ratio of 6:4 was predicted to be the best based on its crystallinity index and the thermal events. As there are many variables involved for further optimization of the formulation, a single design approach is not always adequate. A hybrid-design approach was applied by employing the Plackett Burman design (PBD) for preliminary screening of 7 critical variables, followed by Box-Behnken design (BBD), a sub-type of response surface methodology (RSM) design using 2 relatively significant variables from the former design and incorporating Surfactant/Co-surfactant ratio as the third variable. Comparatively, KolliphorRTM HS15 demonstrated lower Mean Particle Size (PS) & Polydispersity Index (PDI) and KolliphorRTM P188 resulted in Zeta Potential (ZP) ibuprofen thereafter over several hours. These values also confirm that the production method, and all other selected variables, effectively promoted the incorporation of ibuprofen in NLC. Quality by Design (QbD) approach was successfully implemented in developing a robust ophthalmic formulation with superior physicochemical and morphometric properties. NLCs as the

Full Text Available Contact with many different biological membranes goes along the destiny of a drug after its systemic administration. From the circulating macrophage cells to the vessel endothelium, to more complex absorption barriers, the interaction of a biomolecule with these membranes largely affects its rate and time of biodistribution in the body and at the target sites. Therefore, investigating the phenomena occurring on the cell membranes, as well as their different interaction with drugs in the physiological or pathological conditions, is important to exploit the molecular basis of many diseases and to identify new potential therapeutic strategies. Of course, the complexity of the structure and functions of biological and cell membranes, has pushed researchers toward the proposition and validation of simpler two- and three-dimensional membrane models, whose utility and drawbacks will be discussed. This review also describes the analytical methods used to look at the interactions among bioactive compounds with biological membrane models, with a particular accent on the calorimetric techniques. These studies can be considered as a powerful tool for medicinal chemistry and pharmaceutical technology, in the steps of designing new drugs and optimizing the activity and safety profile of compounds already used in the therapy.

OBJECTIVE Given the increasing prevalence of obesity, more patients with a high body mass index (BMI) will require surgical treatment for degenerative spinal disease. In previous investigations of lumbar spine pathology, obesity has been associated with worsened postoperative outcomes and increased costs. However, few studies have examined the association between BMI and postoperative outcomes following anterior cervical discectomy and fusion (ACDF) procedures. Thus, the purpose of this study was to compare surgical outcomes, postoperative narcotics consumption, complications, and hospital costs among BMI stratifications for patients who have undergone primary 1- to 2-level ACDF procedures. METHODS The authors retrospectively reviewed a prospectively maintained surgical database of patients who had undergone primary 1- to 2-level ACDF for degenerative spinal pathology between 2008 and 2015. Patients were stratified by BMI as follows: normal weight (costs. Regression analyses were controlled for preoperative demographic and procedural characteristics. RESULTS Two hundred seventy-seven patients were included in the analysis, of whom 20.9% (n = 58) were normal weight, 37.5% (n = 104) were overweight, 24.9% (n = 69) were obese I, and 16.6% (n = 46) were obese II-III. A higher BMI was associated with an older age (p = 0.049) and increased comorbidity burden (p = 0.001). No differences in sex, smoking status, insurance type, diagnosis, presence of neuropathy, or preoperative VAS pain scores were found among the BMI cohorts (p > 0.05). No significant differences were found among these cohorts as regards operative time, intraoperative blood loss, length of hospital stay, and number of operative levels (p > 0.05). Additionally, no significant differences in postoperative narcotics consumption, VAS score improvement, complication rates, arthrodesis rates, reoperation rates, or total direct costs existed across BMI stratifications (p > 0.05).

Full Text Available Reverse transcriptase (RT is a multifunctional enzyme in the human immunodeficiency virus (HIV-1 life cycle and represents a primary target for drug discovery efforts against HIV-1 infection. Two classes of RT inhibitors, the nucleoside RT inhibitors (NRTIs and the nonnucleoside transcriptase inhibitors are prominently used in the highly active antiretroviral therapy in combination with other anti-HIV drugs. However, the rapid emergence of drug-resistant viral strains has limited the successful rate of the anti-HIV agents. Computational methods are a significant part of the drug design process and indispensable to study drug resistance. In this review, recent advances in computer-aided drug design for the rational design of new compounds against HIV-1 RT using methods such as molecular docking, molecular dynamics, free energy calculations, quantitative structure-activity relationships, pharmacophore modelling and absorption, distribution, metabolism, excretion and toxicity prediction are discussed. Successful applications of these methodologies are also highlighted.

The formulation of the problem in this thesis is: why is the implementation of rehabilitation on underage narcotics users so low. What is the problem with implementing rehabilitation on underage narcotics users? What do the police at Polda Lampung do on underage narcotics users? The result of the research show that the implementation of rehabilitation on underage narcotics users is not in line with state regulations, they are government policy, policy of health minister on technical regulation on medical rehabilitation for the drugs addicts, drugs users, and victim of drugs users, which stated that the underage narcotics users is supposed to be put in rehabilitation but this rule has never been applied on, most of the underage narcotics users were put in jail than on rehabilitation. The problem on rehabilitation is affected by some factors like law structure of Direktorat Narkoba Polda Lampung on the implementation of rehabilitation is not optimal, law culture on the level of obedience of the society about the law is not optimal, and the effort of Kepolisian Daerah Lampung in solving the underage narcotics users is through preemptive, preventive, and repressive way.

Colon-targeted oral drug delivery systems: design trends and approaches.

Amidon, Seth; Brown, Jack E; Dave, Vivek S

2015-08-01

Colon-specific drug delivery systems (CDDS) are desirable for the treatment of a range of local diseases such as ulcerative colitis, Crohn's disease, irritable bowel syndrome, chronic pancreatitis, and colonic cancer. In addition, the colon can be a potential site for the systemic absorption of several drugs to treat non-colonic conditions. Drugs such as proteins and peptides that are known to degrade in the extreme gastric pH, if delivered to the colon intact, can be systemically absorbed by colonic mucosa. In order to achieve effective therapeutic outcomes, it is imperative that the designed delivery system specifically targets the drugs into the colon. Several formulation approaches have been explored in the development colon-targeted drug delivery systems. These approaches involve the use of formulation components that interact with one or more aspects of gastrointestinal (GI) physiology, such as the difference in the pH along the GI tract, the presence of colonic microflora, and enzymes, to achieve colon targeting. This article highlights the factors influencing colon-specific drug delivery and colonic bioavailability, and the limitations associated with CDDS. Further, the review provides a systematic discussion of various conventional, as well as relatively newer formulation approaches/technologies currently being utilized for the development of CDDS.

High-throughput spectrometer designs in a compact form-factor: principles and applications

Science.gov (United States)

Norton, S. M.

2013-05-01

Many compact, portable Raman spectrometers have entered the market in the past few years with applications in narcotics and hazardous material identification, as well as verification applications in pharmaceuticals and security screening. Often, the required compact form-factor has forced designers to sacrifice throughput and sensitivity for portability and low-cost. We will show that a volume phase holographic (VPH)-based spectrometer design can achieve superior throughput and thus sensitivity over conventional Czerny-Turner reflective designs. We will look in depth at the factors influencing throughput and sensitivity and illustrate specific VPH-based spectrometer examples that highlight these design principles.

The aim of this study was to investigate the prevalence and pattern of psychoactive substances among suspected DUID (Driving Under the Influence of Drugs) drivers in Hungary in 2014 and 2015. Blood and/or urine samples of 1252 suspected drivers (600 in 2014 and 652 in 2015) were analyzed for classical illicit and licit drugs, stimulant designer drugs (SDDs), and for synthetic cannabinoids, with 78.3% and 79.6% positive cases for at least one substance in 2014, and 2015, respectively. Impairment was proven in 39.2% (2014) and 35.7% (2015) of all drivers tested, based on the legal criteria of Hungary. Classical illicit drugs were found to be present in blood or urine of 89-61%, drivers tested. Drivers also tested positive for legal medications in 20-22%, SDDs in 21-28%, and synthetic cannabinoids in 15-19% of all cases. This indicates a drop in prevalence for classical illicit drugs and a slight but statistically non-significant increase for the other three substance groups. The distribution of drug types in each category were: [1] classical illicit drugs: cannabis (432), amphetamine (321), and cocaine (79); [2] medicines: alprazolam (94) and clonazepam (36); [3] SDDs: pentedrone (137) and α-PVP (33); [4] synthetic cannabinoids: AB-CHMINACA (46) and MDMB-CHMICA (30). The average age of illicit drug and SDD users was 30 years, while legal medications users were 36 years old on average, and the mean age of synthetic cannabinoid users was 26.5 years. The presence of both alcohol and at least one drug in samples was found in about 10% of the cases, both years. The ratio of multi-drug use was 33.0% in 2014 and 41.3% in 2015. Compared to former years the number of drivers who tested positive for drugs doubled in Hungary, but it is still low compared to alcohol positive cases. The relatively low detected rate of DUID can be explained by (1) combined alcohol consumption masking drug symptoms, (2) the absence of road-side tests for illicit and designer drugs and, (3) police

Abstract Background There is a lack of international research on suicide by drug overdose as a preventable suicide method. Sex- and age-specific rates of suicide by drug self-poisoning (ICD-10, X60-64) and the distribution of drug types used in 16 European countries were studied, and compared with other self-poisoning methods (X65-69) and intentional self-injury (X70-84). Methods Data for 2000-04\\/05 were collected from national statistical offices. Age-adjusted suicide rates, and age and sex distributions, were calculated. Results No pronounced sex differences in drug self-poisoning rates were found, either in the aggregate data (males 1.6 and females 1.5 per 100,000) or within individual countries. Among the 16 countries, the range (from some 0.3 in Portugal to 5.0 in Finland) was wide. \\'Other and unspecified drugs\\' (X64) were recorded most frequently, with a range of 0.2-1.9, and accounted for more than 70% of deaths by drug overdose in France, Luxembourg, Portugal and Spain. Psychotropic drugs (X61) ranked second. The X63 category (\\'other drugs acting on the autonomic nervous system\\') was least frequently used. Finland showed low X64 and high X61 figures, Scotland had high levels of X62 (\\'narcotics and hallucinogens, not elsewhere classified\\') for both sexes, while England exceeded other countries in category X60. Risk was highest among the middle-aged everywhere except in Switzerland, where the elderly were most at risk. Conclusions Suicide by drug overdose is preventable. Intentional self-poisoning with drugs kills as many males as females. The considerable differences in patterns of self-poisoning found in the various European countries are relevant to national efforts to improve diagnostics of suicide and appropriate specific prevention. The fact that vast majority of drug-overdose suicides came under the category X64 refers to the need of more detailed ICD coding system for overdose suicides is needed to permit better design of suicide

The purpose of this paper is to describe HIV-related risk behavior and knowledge of HIV among inmates of Kerobokan prison Bali, Indonesia. A cross-sectional survey of inmates of using a structured questionnaire and sample framework to reflect narcotic use among inmates and the prison gender mix. Among 230 inmates recruited to the study self-reported prevalence of injecting drug use was 7.4 percent (95 percent CI 4.0-10.8 percent). Respondents who participated in a prison based methadone treatment program were all still injecting drugs, these made up 13/17 of the IDU. In total, 47 percent (95 percent CIs 45-55 percent) of respondents who reported injecting also reported sharing needles within the last week. Sexual intercourse while in prison was reported by 3.0 percent (95 percent CI 0.82-5.26 percent) of study respondents. One-third of non-injectors were unaware of the preventative role of condom use. This study suggests that despite harm reduction initiatives within Kerobokan prison HIV risk behavior continues and there is a considerable lack of awareness of the importance of condom use in preventing HIV. The authors relied on self-reported risk behavior that may be subject to reporting bias. The sampling strategy may not reflect the true ratio inmates using or not using narcotics. The current harm reduction approach, including methadone substitution treatment should be optimized within the Indonesian prison setting. This is the first study reporting HIV-related risk behavior from an Indonesian prison with an established methadone substitution program.

This study aimed to determine design features of a drug-checking service that would be feasible, attractive and likely to be used by Australian festival and nightlife attendees. Web survey of 851 Australians reporting use of psychostimulants and/or hallucinogens and attendance at licensed venues past midnight and/or festivals in the past year (70% male; median age 23 years). A drug-checking service located at festivals or clubs would be used by 94%; a fixed-site service external to such events by 85%. Most (80%) were willing to wait an hour for their result. Almost all (94%) would not use a service if there was a possibility of arrest, and a majority (64%) would not use a service that did not provide individual feedback of results. Drug-checking results were only slightly more attractive if they provided comprehensive quantitative results compared with qualitative results of key ingredients. Most (93%) were willing to pay up to $5, and 68% up to $10, per test. One-third (33%) reported willingness to donate a whole dose for testing: they were more likely to be male, younger, less experienced, use drugs more frequently and attend venues/festivals less frequently. In this sample, festival- or club-based drug-checking services with low wait times and low cost appear broadly attractive under conditions of legal amnesty and individualised feedback. Quantitative analysis of ecstasy pills requiring surrender of a whole pill may appeal to a minority in Australia where pills are more expensive than elsewhere.

Full Text Available While a typical way for diabetes therapy is discrete insulin infusion based on long-time interval measurement, in this paper, we design a closed-loop control system for continuous drug infusion to improve the traditional discrete methods and make diabetes therapy automatic in practice. By exploring the accumulative function of drug to insulin, a continuous injection model is proposed. Based on this model, proportional-integral-derivative (PID and fuzzy logic controllers are designed to tackle a control problem of the resulting highly nonlinear plant. Even with serious disturbance of glucose, such as nutrition absorption at meal time, the proposed scheme can perform well in simulation experiments.

Fragment-based quantitative structure-activity relationship (FB-QSAR) for fragment-based drug design.

In cooperation with the fragment-based design a new drug design method, the so-called "fragment-based quantitative structure-activity relationship" (FB-QSAR) is proposed. The essence of the new method is that the molecular framework in a family of drug candidates are divided into several fragments according to their substitutes being investigated. The bioactivities of molecules are correlated with the physicochemical properties of the molecular fragments through two sets of coefficients in the linear free energy equations. One coefficient set is for the physicochemical properties and the other for the weight factors of the molecular fragments. Meanwhile, an iterative double least square (IDLS) technique is developed to solve the two sets of coefficients in a training data set alternately and iteratively. The IDLS technique is a feedback procedure with machine learning ability. The standard Two-dimensional quantitative structure-activity relationship (2D-QSAR) is a special case, in the FB-QSAR, when the whole molecule is treated as one entity. The FB-QSAR approach can remarkably enhance the predictive power and provide more structural insights into rational drug design. As an example, the FB-QSAR is applied to build a predictive model of neuraminidase inhibitors for drug development against H5N1 influenza virus. (c) 2008 Wiley Periodicals, Inc.

Chemically-triggered drug delivery systems (DDSs) have been extensively studied as they do not require specialized equipment to deliver the drug and can deeply penetrate human tissue. However, their syntheses are complicated and they tend to be cytotoxic, which restricts their clinical utility. In this work, the self-regulated drug loading and release capabilities of peptide-protected gold nanoclusters (Pep-Au NCs) are investigated using vancomycin (Van) as the model drug. Gold nanoclusters (Au NCs) coated with a custom-designed pentapeptide are synthesized as drug delivery nanocarriers and loaded with Van - a spontaneous process reliant on the specific binding between Van and the custom-designed peptide. The Van-loaded Au NCs show comparable antimicrobial activity with Van on its own, and the number of Van released by the Pep-Au NCs is found to be proportional to the amount of bacteria present. The controlled nature of the Van release is very encouraging, and predominantly due to the stronger binding affinity of Van with bacteria than that with Au NCs. In addition, these fluorescent Au NCs could also be used to construct temperature sensors, which enable the in vitro and in vivo bioimaging.

Computer-aided drug design plays an important role in medicinal chemistry to obtain insights into molecular mechanisms and to prioritize design strategies. Although significant improvement has been made in structure based design, it still remains a key challenge to accurately model and predict induced fit mechanisms. Most of the current available techniques either do not provide sufficient protein conformational sampling or are too computationally demanding to fit an industrial setting. The current study presents a systematic and exhaustive investigation of predicting binding modes for a range of systems using PELE (Protein Energy Landscape Exploration), an efficient and fast protein-ligand sampling algorithm. The systems analyzed (cytochrome P, kinase, protease, and nuclear hormone receptor) exhibit different complexities of ligand induced fit mechanisms and protein dynamics. The results are compared with results from classical molecular dynamics simulations and (induced fit) docking. This study shows that ligand induced side chain rearrangements and smaller to medium backbone movements are captured well in PELE. Large secondary structure rearrangements, however, remain challenging for all employed techniques. Relevant binding modes (ligand heavy atom RMSD PELE method within a few hours of simulation, positioning PELE as a tool applicable for rapid drug design cycles.

The current retrospective study was completed with the aim to identify demographic characteristics and clinical predictors (if any) of the patients discharged from our pain clinic due to breach in narcotic use contract (BNUC). Retrospective patient charts' review and data audit. University hospital-affiliated pain clinic in the United States. All patient charts in our pain clinic for a 2-year period (2011-2012). The patients with BNUC were delineated from the patients who had not been discharged from our pain clinic. Pain characteristics, pain management, and substance abuse status were compared in each patient with BNUC between the time of admission and the time of discharge. The patients with BNUC discharges showed significant variability for the discharging factors among the pain physicians within a single pain clinic model with this variability being dependent on their years of experience and their proactive interventional pain management. The patients with BNUC in our pain clinic setting were primarily middle-aged, obese, unmarried males with nondocumented stable occupational history who were receiving only noninterventional pain management. Substance abuse, doctor shopping, and potential diversion were the top three documented reasons for BNUC discharges. In 2011-2012, our pain clinic discharged 1-in-16 patients due to breach in narcotic use contract.

A pharmacy department's change from indexed sequential access files to a data base management system (DBMS) for purposes of automated inventory control is described. The DBMS has three main functional areas: (1) inventory ordering and accountability, (2) charging of interdepartmental and intradepartmental orders, and (3) data manipulation with report design for management control. There are seven files directly related to the inventory ordering and accountability area. Each record can be accessed directly or through another file. Information on the quantity of a drug on hand, drug(s) supplied by a specific vendor, status of a purchase order, or calculation of an estimated order quantity can be retrieved quickly. In the drug master file, two records contain a reorder point and safety-stock level that are determined by searching the entries in the order history file and vendor master file. The intradepartmental and interdepartmental orders section contains five files assigned to record and store information on drug distribution. All items removed from the stockroom and distributed are recorded, and reports can be generated for itemized bills, total cost by area, and as formatted files for the accounts payable department. The design, development, and implementation of the DBMS took approximately a year using a part-time pharmacist and minimal outside help, while the previous system required constant expensive help of a programmer/analyst. The DBMS has given the pharmacy department a flexible inventory management system with increased drug control, decreased operating expenses, increased use of department personnel, and the ability to develop and enhance other systems.

The rapid development of nanotechnology provides alternative approaches to overcome several limitations of conventional anti-cancer therapy. Drug targeting using functionalized nanoparticles to advance their transport to the dedicated site, became a new standard in novel anti-cancer methods. In effect, the employment of nanoparticles during design of antineoplastic drugs helps to improve pharmacokinetic properties, with subsequent development of high specific, non-toxic and biocompatible anti-cancer agents. However, the physicochemical and biological diversity of nanomaterials and a broad spectrum of unique features influencing their biological action requires continuous research to assess their activity. Among numerous nanosystems designed to eradicate cancer cells, only a limited number of them entered the clinical trials. It is anticipated that progress in development of nanotechnology-based anti-cancer materials will provide modern, individualized anti-cancer therapies assuring decrease in morbidity and mortality from cancer diseases. In this review we discussed the implication of nanomaterials in design of new drugs for effective antineoplastic therapy and describe a variety of mechanisms and challenges for selective tumor targeting. We emphasized the recent advantages in the field of nanotechnology-based strategies to fight cancer and discussed their part in effective anti-cancer therapy and successful drug delivery.

2014-08-01

Full Text Available Background: Severe abdominal pain is not common after laparoscopic surgeries, but acute or chronic pain after operation is considerable in some patients. Post-operative Pain control after laparoscopic surgeries, is conventionally achieved using analgesics such as non-steroidal anti-inflammatory drugs (NSAIDs and narcotics, but their administration has a lot of side effects. This study compares the efficacy and side effects of local anesthetic drugs versus conventional analgesics in post-operative pain control.Materials and Methods: This prospective investigation was conducted into two groups of patients (n=93. Group 1, as control group, was given conventional analgesics such as narcotics and NSAIDs. In investigational group, at the end of laparoscopic surgery, prior to port withdrawal, a local anesthetic mixture, a short acting (Lidocaine 2% plus a long acting (Bupivacaine 0.5% is instilled through the port lumen between the abdominal wall layers. The efficacy of both types of medications was compared to their efficacy and side effects.Results: 85% of the control group, received 5 to 20 ml Morphine for pain control while the others were controlled with trans-rectal NSAIDs. In the treatment group, the pain of 65% of the patients was controlled only by local anesthetic drugs, 30% required NSAIDs and the other 5% required narcotics administration for pain control.Conclusion: The administration of local anesthetic drugs after laparoscopic surgery is an effective method for pain control with a low complications rate and side effects of narcotics.

Application of Quality by Design (QbD) Principles to Extractables/Leachables Assessment. Establishing a Design Space for Terminally Sterilized Aqueous Drug Products Stored in a Plastic Packaging System.

Science.gov (United States)

Jenke, Dennis

2010-01-01

The concept of quality by design (QbD) reflects the current global regulatory thinking related to pharmaceutical products. A cornerstone of the QbD paradigm is the concept of a design space, where the design space is a multidimensional combination of input variables and process parameters that have been demonstrated to provide the assurance of product quality. If a design space can be established for a pharmaceutical process or product, then operation within the design space confirms that the product or process output possesses the required quality attributes. This concept of design space can be applied to the safety (leachables) assessment of drug products manufactured and stored in packaging systems. Critical variables in such a design space would include those variables that affect the interaction of the drug product and its packaging, including (a) composition of the drug product, (b) composition of the packaging system, (c) configuration of the packaging system, and (d) the conditions of contact. This paper proposes and justifies such a leachables design space for aqueous drug products packaged in a specific plastic packaging system. Such a design space has the following boundaries:Aqueous drug products with a pH in the range of 2 to 8 and that contain no polarity-impacting agents such as organic solubilizers and stabilizers (addressing variable a). Packaging systems manufactured from materials that meet the system's existing material specifications (addressing variable b). Nominal fill volumes from 50 to 1000 mL (addressing variable c). Products subjected to terminal sterilization and then stored at room temperature for a period of up to 24 months (addressing variable d). The ramification of such a design space is that any drug product that falls within these boundaries is deemed to be compatible with the packaging system, from the perspective of safety, without the requirement of supporting drug product testing. When drug products are packaged in plastic

The aim of the present study was to investigate whether differences in total and peak drug exposure upon generic substitution are due to differences between formulations or to intrasubject pharmacokinetic variability of the active substance. The study was designed as a retrospective reanalysis of existing studies. Nine replicate design bioequivalence studies representing six drug classes - i.e. for alendronate, atorvastatin, cyclosporin, ebastine, exemestane, mycophenolate mofetil, and ropinirole - were retrieved from the Dutch Medicines Regulatory Authority. In most studies, the intrasubject variability in total and peak drug exposure was comparable for the brand-name [in the range 0.01-0.24 for area under the concentration-time curve (AUCt ) and 0.02-0.29 for peak plasma concentration (Cmax ) on a log scale] and generic (0.01-0.23 for AUCt and 0.08-0.33 for Cmax ) drugs, and was comparable with the intrasubject variability upon switching between those drugs (0.01-0.23 for AUCt and 0.06-0.33 for Cmax ). The variance related to subject-by-formulation interaction could be considered negligible (-0.069 to 0.047 for AUCt and -0.091 to 0.02 for Cmax ). In the investigated studies, the variation in total and peak exposure seen when a patient is switched from a brand-name to a generic drug is comparable with that seen following repeated administration of the brand-name drug in the patient. Only the intrasubject variability seems to play a crucial and decisive role in the variation in drug exposure seen; no additional formulation-dependent variation in exposure is observed upon switching. Thus, our data support that, for the medicines that were included in the present investigation, from a clinical pharmacological perspective, the benefit-risk balance of a generic drug is comparable with that of the brand-name drug. © 2015 The British Pharmacological Society.

Using well-characterized chemical reactions and readily available monomers, chemists are able to create sets of compounds, termed libraries, which are useful in drug discovery processes. The design of combinatorial chemical libraries can be complex and there has been much information recently published offering suggestions on how the design process can be carried out. This review focuses on literature with the goal of organizing current thinking. At this point in time, it is clear that benchmarking of current suggested methods is required as opposed to further new methods.

Drug prescription and administration processes strongly impact on the occurrence of risks in medical settings for they can be sources of adverse drug events (ADEs). A properly engineered use of information and communication technologies has proven to be a promising approach to reduce these risks. In this study, we propose PHARMA, a web information system which supports healthcare staff in the secure cooperative execution of drug prescription, transcription and registration tasks. PHARMA allows the easy sharing and management of documents containing drug-related information (i.e., drug prescriptions, medical reports, screening), which is often inconsistent and scattered across different information systems and heterogeneous organization domains (e.g., departments, other hospital facilities). PHARMA enables users to access such information in a consistent and secure way, through the adoption of REST and web-oriented design paradigms and protocols. We describe the implementation of the PHARMA prototype, and we discuss the results of the usability evaluation that we carried out with the staff of a hospital in Florence, Italy.

Metal complexes in cancer therapy – an update from drug design perspective

Full Text Available Umar Ndagi, Ndumiso Mhlongo, Mahmoud E Soliman Molecular Modelling and Drug Design Research Group, School of Health Sciences, University of KwaZulu-Natal, Westville, Durban, South Africa Abstract: In the past, metal-based compounds were widely used in the treatment of disease conditions, but the lack of clear distinction between the therapeutic and toxic doses was a major challenge. With the discovery of cisplatin by Barnett Rosenberg in 1960, a milestone in the history of metal-based compounds used in the treatment of cancers was witnessed. This forms the foundation for the modern era of the metal-based anticancer drugs. Platinum drugs, such as cisplatin, carboplatin and oxaliplatin, are the mainstay of the metal-based compounds in the treatment of cancer, but the delay in the therapeutic accomplishment of other metal-based compounds hampered the progress of research in this field. Recently, however, there has been an upsurge of activities relying on the structural information, aimed at improving and developing other forms of metal-based compounds and nonclassical platinum complexes whose mechanism of action is distinct from known drugs such as cisplatin. In line with this, many more metal-based compounds have been synthesized by redesigning the existing chemical structure through ligand substitution or building the entire new compound with enhanced safety and cytotoxic profile. However, because of increased emphasis on the clinical relevance of metal-based complexes, a few of these drugs are currently on clinical trial and many more are awaiting ethical approval to join the trial. In this review, we seek to give an overview of previous reviews on the cytotoxic effect of metal-based complexes while focusing more on newly designed metal-based complexes and their cytotoxic effect on the cancer cell lines, as well as on new approach to metal-based drug design and molecular target in cancer therapy. We are optimistic that the concept of selective

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.

Over the last decade, deep learning (DL) methods have been extremely successful and widely used to develop artificial intelligence (AI) in almost every domain, especially after it achieved its proud record on computational Go. Compared to traditional machine learning (ML) algorithms, DL methods still have a long way to go to achieve recognition in small molecular drug discovery and development. And there is still lots of work to do for the popularization and application of DL for research purpose, e.g., for small molecule drug research and development. In this review, we mainly discussed several most powerful and mainstream architectures, including the convolutional neural network (CNN), recurrent neural network (RNN), and deep auto-encoder networks (DAENs), for supervised learning and nonsupervised learning; summarized most of the representative applications in small molecule drug design; and briefly introduced how DL methods were used in those applications. The discussion for the pros and cons of DL methods as well as the main challenges we need to tackle were also emphasized.

Toxicity is a common drawback of newly designed chemotherapeutic agents. With the exception of pharmacophore-induced toxicity (lack of selectivity at higher concentrations of a drug), the toxicity due to chemotherapeutic agents is based on the toxicophore moiety present in the drug. To date, methodologies implemented to determine toxicophores may be broadly classified into biological, bioanalytical and computational approaches. The biological approach involves analysis of bioactivated metabolites, whereas the computational approach involves a QSAR-based method, mapping techniques, an inverse docking technique and a few toxicophore identification/estimation tools. Being one of the major steps in drug discovery process, toxicophore identification has proven to be an essential screening step in drug design and development. The paper is first of its kind, attempting to cover and compare different methodologies employed in predicting and determining toxicophores with an emphasis on their scope and limitations. Such information may prove vital in the appropriate selection of methodology and can be used as screening technology by researchers to discover the toxicophoric potentials of their designed and synthesized moieties. Additionally, it can be utilized in the manipulation of molecules containing toxicophores in such a manner that their toxicities might be eliminated or removed.

There are about 60,000 chemical substances which may cause poisoning. Identifying the cause substances is, therefore, very important for patient at emergency department. Triage is an immunoassay kit for the qualitative test for the metabolites of 8 major abuse drugs in urine. We assessed the usefullness of Triage on two patient groups. The first Group consists of the patients considered having not taken substances at initial diagnosis; the second Group consists of the patients considered having taken substances. The result are as follows. 1) The rate of Triage positive patients in the first Group were: attempt-suicide 23%, coma 24%, shock 10%, trauma 7%, respectively. Except for the habitually used medicine, narcotic and stimulant drugs were detected. In the first Group, negative result of Triage was effective in diagnosing the patients as not poisoned, excluding the possitivity of 8 major drugs usage. 2) The rate of Triage positive patients in the second Group were very high: attempt-suicide 77%, coma 51%, shock 57%, trauma 30%, respectively, showing mostly any of 8 major drugs were the cause of poisoning. In the second Group, positive result of Triage was effective in diagnosing the patient as poisoning or as coexisting poisoning with other diseases. 3) The specificity of Triage diagnosis in the first Group was 80% (113/142). The specificity and the sensitivity in the second Group were 64% (50/78) and 97% (74/76), respectively. These results means that Triage is very useful for diagnosis on 8 major drugs poisoning. 4) Triage is efficient for identifying the cause substances in drug poisoning and, therefore, can save medical expense. Triage is a very useful test kit at emergency department.

Complex Networks are useful in solving problems in drug research and industry, developing mathematical representations of different systems. These systems move in a wide range from relatively simple graph representations of drug molecular structures to large systems. We can cite for instance, drug-target protein interaction networks, drug policy legislation networks, or drug treatment in large geographical disease spreading networks. In any case, all these networks have essentially the same components: nodes (atoms, drugs, proteins, microorganisms and/or parasites, geographical areas, drug policy legislations, etc.) and edges (chemical bonds, drug-target interactions, drug-parasite treatment, drug use, etc.). Consequently, we can use the same type of numeric parameters called Topological Indices (TIs) to describe the connectivity patterns in all these kinds of Complex Networks despite the nature of the object they represent. The main reason for this success of TIs is the high flexibility of this theory to solve in a fast but rigorous way many apparently unrelated problems in all these disciplines. Another important reason for the success of TIs is that using these parameters as inputs we can find Quantitative Structure-Property Relationships (QSPR) models for different kind of problems in Computer-Aided Drug Design (CADD). Taking into account all the above-mentioned aspects, the present work is aimed at offering a common background to all the manuscripts presented in this special issue. In so doing, we make a review of the most common types of complex networks involving drugs or their targets. In addition, we review both classic TIs that have been used to describe the molecular structure of drugs and/or larger complex networks. Next, we use for the first time a Markov chain model to generalize Galvez TIs to higher order analogues coined here as the Markov-Galvez TIs of order k (MGk). Lastly, we illustrate the calculation of MGk values for different classes of

An adaptive drug delivery design using neural networks for effective treatment of infectious diseases: a simulation study.

Science.gov (United States)

Padhi, Radhakant; Bhardhwaj, Jayender R

2009-06-01

An adaptive drug delivery design is presented in this paper using neural networks for effective treatment of infectious diseases. The generic mathematical model used describes the coupled evolution of concentration of pathogens, plasma cells, antibodies and a numerical value that indicates the relative characteristic of a damaged organ due to the disease under the influence of external drugs. From a system theoretic point of view, the external drugs can be interpreted as control inputs, which can be designed based on control theoretic concepts. In this study, assuming a set of nominal parameters in the mathematical model, first a nonlinear controller (drug administration) is designed based on the principle of dynamic inversion. This nominal drug administration plan was found to be effective in curing "nominal model patients" (patients whose immunological dynamics conform to the mathematical model used for the control design exactly. However, it was found to be ineffective in curing "realistic model patients" (patients whose immunological dynamics may have off-nominal parameter values and possibly unwanted inputs) in general. Hence, to make the drug delivery dosage design more effective for realistic model patients, a model-following adaptive control design is carried out next by taking the help of neural networks, that are trained online. Simulation studies indicate that the adaptive controller proposed in this paper holds promise in killing the invading pathogens and healing the damaged organ even in the presence of parameter uncertainties and continued pathogen attack. Note that the computational requirements for computing the control are very minimal and all associated computations (including the training of neural networks) can be carried out online. However it assumes that the required diagnosis process can be carried out at a sufficient faster rate so that all the states are available for control computation.

2014-01-01

Recent advances in the understanding of molecular recognition and protein–ligand interactions have facilitated rapid development of potent and selective ligands for therapeutically relevant targets. Over the past two decades, a variety of useful approaches and emerging techniques have been developed to promote the identification and optimization of leads that have high potential for generating new therapeutic agents. Intriguingly, the innovation of a fragment-based drug design (FBDD) approach has enabled rapid and efficient progress in drug discovery. In this critical review, we focus on the construction of fragment libraries and the advantages and disadvantages of various fragment-based screening (FBS) for constructing such libraries. We also highlight the deconstruction–reconstruction strategy by utilizing privileged fragments of reported ligands. PMID:25263697

2015-01-01

Drug use is one of the fundamental problems of the contemporary world. Due to the debilitating effects on physical and mental health and the possibility of impaired social functions, it is extremely important to assess exposure to psychoactive substances among high-risk groups. Taking into account characteristics of adolescence, one of them includes young people. To assess the exposure of young people to drugs, survey research is the most commonly use. To establish reliability of the information indicated by the students, toxicological studies could be a good manner. High-performance liquid chromatography coupled with mass spectrometry (LC-MS) is currently one of the most common techniques use for the detection and determination of psychoactive substances in biological material. In practice, an important issue in toxicological studies is the selection of a suitable biological material. Taking into account economic considerations and the method of sampling, the saliva is an increasingly used alternative material. The aim of this study was to assess the exposure of junior high school students on psychoactive substances--designer drugs, through the analysis of surveys and qualitative analysis of saliva taken from teenagers. It has been shown that surveys are a relatively quick and easy form of assessing the exposure of young people to psychoactive substances, but require verification through toxicological analysis of biological material for the presence of psychoactive substances for their reliability. Poznan secondary school students experimented with designer drugs at a similar level as respondents of nationwide survey from 2013.

Most likely, opium was the first narcotic substance discovered at the dawn of humankind. The history of drug addiction is immensely rich and allows for tracing the long way humankind had to travel to reach the contemporary level of consciousness with respect to narcotic substances. A retrospective view of drug addiction that takes into consideration the historical context, while extending our knowledge, also allows for a better understanding of today's problems. The report presents elements of a retrospective view of problems associated with addiction to opium, morphine and heroin over the centuries, what is a subject of scientific interest in contemporary toxicology.

Kim, Hai-Young; Wyss, Daniel F

2015-01-01

Fragment-based drug design (FBDD) comprises both fragment-based screening (FBS) to find hits and elaboration of these hits to lead compounds. Typical fragment hits have lower molecular weight (FBDD since it identifies and localizes the binding site of weakly interacting hits on the target protein. Here we describe ligand-based NMR methods for hit identification from fragment libraries and for functional cross-validation of primary hits.

poolHiTS: A Shifted Transversal Design based pooling strategy for high-throughput drug screening

Directory of Open Access Journals (Sweden)

Woolf Peter J

2008-05-01

Full Text Available Abstract Background A key goal of drug discovery is to increase the throughput of small molecule screens without sacrificing screening accuracy. High-throughput screening (HTS in drug discovery involves testing a large number of compounds in a biological assay to identify active compounds. Normally, molecules from a large compound library are tested individually to identify the activity of each molecule. Usually a small number of compounds are found to be active, however the presence of false positive and negative testing errors suggests that this one-drug one-assay screening strategy can be significantly improved. Pooling designs are testing schemes that test mixtures of compounds in each assay, thereby generating a screen of the whole compound library in fewer tests. By repeatedly testing compounds in different combinations, pooling designs also allow for error-correction. These pooled designs, for specific experiment parameters, can be simply and efficiently created using the Shifted Transversal Design (STD pooling algorithm. However, drug screening contains a number of key constraints that require specific modifications if this pooling approach is to be useful for practical screen designs. Results In this paper, we introduce a pooling strategy called poolHiTS (Pooled High-Throughput Screening which is based on the STD algorithm. In poolHiTS, we implement a limit on the number of compounds that can be mixed in a single assay. In addition, we show that the STD-based pooling strategy is limited in the error-correction that it can achieve. Due to the mixing constraint, we show that it is more efficient to split a large library into smaller blocks of compounds, which are then tested using an optimized strategy repeated for each block. We package the optimal block selection algorithm into poolHiTS. The MATLAB codes for the poolHiTS algorithm and the corresponding decoding strategy are also provided. Conclusion We have produced a practical version

Rectal drug administration: clinical pharmacokinetic considerations.

The human rectum represents a body cavity in which drugs can be easily introduced and retained and from which absorption is well possible. There are important therapeutic reasons why it is sometimes preferable to give a drug rectally rather than orally, e.g. in cases of nausea and vomiting. Drawbacks of rectal drug administration include the interruption of absorption by defaecation and lack of patient acceptability. The mechanism of drug absorption from the rectum is probably no different to that in the upper part of the gastrointestinal tract, despite the fact that the physiological circumstances (e.g. pH, fluid content) differ substantially, Absorption from aqueous and alcoholic solutions may occur very rapidly, which has proved to be of considerable therapeutic value in the rapid suppression of acute convulsive attacks by diazepam (e.g. in children), but absorption from suppositories is generally slower and very much dependent on the nature of the suppository base, the use of surfactants or other additives, particle size of the active ingredient, etc. There is some evidence that hepatic first-pass elimination of high clearance drugs is partially avoided after rectal administration, e.g. lignocaine. This can be explained by the rectal venous blood supply: the upper part is connected with the portal system, whereas the lower part is directly connected with the systemic circulation. Plasma concentration data following rectal administration of representatives of several classes of drugs are reviewed: anticonvulsants, non-narcotic analgesics and non-steroidal anti-inflammatory agents, hypnosedatives and anaesthetics, strong analgesics, theophylline and derivatives, corticosteroids, antibacterial agents, thiazinamium, promethazine, hyoscine-N-butyl-bromide, streptokinase, progesterone, ergotamine tartrate and levodopa. Only limited number of cases has it been adequately shown that the rectal route of administration gives plasma concentrations which are comparable to

2014-01-01

For many teenagers the time of growing up is a period of trying prohibited substances. Nowadays apart from alcohol and tobacco new designed, psychoactive substances known as "smart drugs" or "legal highs" are available. Intensive development of their market is taking place in the last few years which is difficult to overcome by regulations only. Toxicological tests used now are not able to detect the presence of many such substances in the body. Designer drugs cause the interest of young people even from small towns and many times taking them give effects requiring medical help. Caffeine is also a psychoactive substance but depending on the dose it can have positive or detrimental effect. Recently there are more and more products with caffeine, especially drinks and dietary supplements, what can cause the increase of consumption of caffeine. Children are particularly exposed to the adverse effect of high consumption of caffeine because of their small body weight and development of the central nervous system. This article presents actual data about the market of designer drugs, frequency of using them, consumption of caffeine by children and teenagers and about the impact of these substances on the organism.

Ebola virus: A gap in drug design and discovery - experimental and computational perspective.

Balmith, Marissa; Faya, Mbuso; Soliman, Mahmoud E S

2017-03-01

The Ebola virus, formally known as the Ebola hemorrhagic fever, is an acute viral syndrome causing sporadic outbreaks that have ravaged West Africa. Due to its extreme virulence and highly transmissible nature, Ebola has been classified as a category A bioweapon organism. Only recently have vaccine or drug regimens for the Ebola virus been developed, including Zmapp and peptides. In addition, existing drugs which have been repurposed toward anti-Ebola virus activity have been re-examined and are seen to be promising candidates toward combating Ebola. Drug development involving computational tools has been widely employed toward target-based drug design. Screening large libraries have greatly stimulated research toward effective anti-Ebola virus drug regimens. Current emphasis has been placed on the investigation of host proteins and druggable viral targets. There is a huge gap in the literature regarding guidelines in the discovery of Ebola virus inhibitors, which may be due to the lack of information on the Ebola drug targets, binding sites, and mechanism of action of the virus. This review focuses on Ebola virus inhibitors, drugs which could be repurposed to combat the Ebola virus, computational methods which study drug-target interactions as well as providing further insight into the mode of action of the Ebola virus. © 2016 John Wiley & Sons A/S.

Evaluating a policing strategy intended to disrupt an illicit street-level drug market.

Corsaro, Nicholas; Brunson, Rod K; McGarrell, Edmund F

2010-12-01

The authors examined a strategic policing initiative that was implemented in a high crime Nashville, Tennessee neighborhood by utilizing a mixed-methodological evaluation approach in order to provide (a) a descriptive process assessment of program fidelity; (b) an interrupted time-series analysis relying upon generalized linear models; (c) in-depth resident interviews. Results revealed that the initiative corresponded with a statistically significant reduction in drug and narcotics incidents as well as perceived changes in neighborhood disorder within the target community. There was less-clear evidence, however, of a significant impact on other outcomes examined. The implications that an intensive crime prevention strategy corresponded with a reduction in specific forms of neighborhood crime illustrates the complex considerations that law enforcement officials face when deciding to implement this type of crime prevention initiative.

1986-01-01

The article provides an integrated picture of the drug abuse situation in Egypt based on a series of large scale field surveys that the authors have conducted since 1957. Apart from the consumption of alcohol and tobacco, the results of the surveys show that cannabis remains the most widely abused psycho-active substance in Egypt. Cannabis use has been known in the country for a long time. The abuse of psychotropic substances emerged as a problem during the 1970s and has remained one of the major drug problems ever since. The abuse of cocaine and heroin first emerged as a problem in the period following the First World War. It disappeared during the early 1930s, when the country was struck by an economic crisis, only to re-emerge during the 1980s. The most recent surveys show that 30 per cent of male industrial workers and 20 per cent of male students have used drugs at some time in their lives, and, among them, approximately 25 per cent have continued to do so. The respondents rank alcohol as the most frequently abused substance, followed by natural narcotics (e.g. cannabis and opiates) and psychotropic substances. The first use of alcohol and cannabis most often occurs during some social occasion or in the company of friends, while the first use of psychotropic substances is usually an effort to cope with psychological or physical discomfort, or stress-triggering situations. In general, it is the drug users, rather than the non-users, who hear about drugs, see drugs and have personal friends and relatives who themselves abuse drugs.

2015-01-01

Design of experiments (DOE), a component of Quality by Design (QbD), is systematic and simultaneous evaluation of process variables to develop a product with predetermined quality attributes. This article presents a case study to understand the effects of process variables in a bead milling process used for manufacture of drug nanoparticles. Experiments were designed and results were computed according to a 3-factor, 3-level face-centered central composite design (CCD). The factors investigated were motor speed, pump speed and bead volume. Responses analyzed for evaluating these effects and interactions were milling time, particle size and process yield. Process validation batches were executed using the optimum process conditions obtained from software Design-Expert® to evaluate both the repeatability and reproducibility of bead milling technique. Milling time was optimized to process variables by applying DOE resulted in considerable decrease in milling time to achieve the desired particle size. The study indicates the applicability of DOE approach to optimize critical process parameters in the manufacture of drug nanoparticles.

Full Text Available Tramadol HCL is a centrally acting opioid analgesic. Although the drug has a higher plasma half life, the steady state plasma concentration is not achieved with frequent dosing of q.i.d at 6 hour intervals. Therefore, the objective of the present work was to formulate a 100mg strength Tramadol matrix tablets to extend the drug release and thus decrease the dosing frequency and achieve steady state plasma concentration. Initially, preformulation studies were carried out to rule out any incompatibility between the drug and the chosen polymer(s after exposing physical mixtures of the drug and the polymer(s to 40 and deg;C/75% RH for three months. A suitable method was developed for drug estimation at 271nm by a UV double beam spectrophotometer. Next, various batches of tablets were designed using different polymers such as Ethylcellulose, Carnauba wax, HPMC-K100M, Carbopol-974P and Kollidon-SR. Direct compression technique was used except for the formulation containing carnauba wax for which melt granulation was done followed by compression. Formulations F-1 to F-15 contained single polymers in increasing concentrations in drug:polymer ratios of 1:1, 1:2 and 1:3 where it was observed that the drug release extended with increasing polymer concentrations. Carbopol-974P extended drug release better followed by HPMC-K100M and Carnauba wax compared to other polymers. A combination of these polymers was also used at various ratios to get formulations F-16 to F-20 and observed that the polymer combinations controlled drug release better. The type of fillers like lactose and microcrystalline cellulose had no effect on the physiochemical characters as well as on the drug release profiles. The in vitro release data from the best formulation fitted well in Higuchi as well as Peppas model, the and #8216;n and #8217; value, which confirmed that the release mechanism shifted from initial dissolution to later extended diffusion in which both diffusion and erosion

The impact of pharmacophore modeling in drug design.

2005-07-01

With the reliable use of computer simulations in scientific research, it is possible to achieve significant increases in productivity as well as a reduction in research costs compared with experimental approaches. For example, computer-simulation can substantially enchance productivity by focusing the scientist to better, more informed choices, while also driving the 'fail-early' concept to result in a significant reduction in cost. Pharmacophore modeling is a reliable computer-aided design tool used in the discovery of new classes of compounds for a given therapeutic category. This commentary will briefly review the benefits and applications of this technology in drug discovery and design, and will also highlight its historical evolution. The two most commonly used approaches for pharmacophore model development will be discussed, and several examples of how this technology was successfully applied to identify new potent leads will be provided. The article concludes with a brief outline of the controversial issue of patentability of pharmacophore models.

Evaluation of optimized bronchoalveolar lavage sampling designs for characterization of pulmonary drug distribution.

Science.gov (United States)

Clewe, Oskar; Karlsson, Mats O; Simonsson, Ulrika S H

2015-12-01

Bronchoalveolar lavage (BAL) is a pulmonary sampling technique for characterization of drug concentrations in epithelial lining fluid and alveolar cells. Two hypothetical drugs with different pulmonary distribution rates (fast and slow) were considered. An optimized BAL sampling design was generated assuming no previous information regarding the pulmonary distribution (rate and extent) and with a maximum of two samples per subject. Simulations were performed to evaluate the impact of the number of samples per subject (1 or 2) and the sample size on the relative bias and relative root mean square error of the parameter estimates (rate and extent of pulmonary distribution). The optimized BAL sampling design depends on a characterized plasma concentration time profile, a population plasma pharmacokinetic model, the limit of quantification (LOQ) of the BAL method and involves only two BAL sample time points, one early and one late. The early sample should be taken as early as possible, where concentrations in the BAL fluid ≥ LOQ. The second sample should be taken at a time point in the declining part of the plasma curve, where the plasma concentration is equivalent to the plasma concentration in the early sample. Using a previously described general pulmonary distribution model linked to a plasma population pharmacokinetic model, simulated data using the final BAL sampling design enabled characterization of both the rate and extent of pulmonary distribution. The optimized BAL sampling design enables characterization of both the rate and extent of the pulmonary distribution for both fast and slowly equilibrating drugs.

Full Text Available Objective . We present the clinical, biochemical, and imaging findings of a woman with vitamin D deficiency and severe osteomalacia related to intravenous heroin addiction. Results . A 54-year-old woman with a medical history significant for long-standing heroin abuse presented with complaints of bone pain, muscle cramping, and a left hip ulcer. She had been bed bound for approximately 1 year secondary to pain of uncertain etiology, and her husband was bringing her both food and drugs. She was admitted to the hospital for debridement of a right ischial ulcer. Further workup revealed osteomyelitis of the left hip and severe vitamin D deficiency. Radiologic evaluation demonstrated diffuse osteopenia with pseudofractures, as well as true fractures. Conclusion . This is the first case reported in the English literature of advanced osteomalacia resulting from a debilitating narcotic dependency. Vitamin D deficiency should be considered in patients with poor nutrition and prolonged sunlight deprivation from any cause.

This study aims to investigate factors affecting weakly basic drugs liposomal systems. Resolution V fractional factorial design (2 V 5-1 ) is used as an example of screening designs that would better be used as a wise step before proceeding with detailed factors effects or optimization studies. Five factors probable to affect liposomal systems of weakly basic drugs were investigated using Amisulpride as a model drug. Factors studied were; A: Preparation technique B: Phosphatidyl choline (PhC) amount (mg) C: Cholesterol: PhC molar ratio, D: Hydration volume (ml) and E: Sonication type. Levels investigated were; Ammonium sulphate-pH gradient technique or Transmembrane zinc chelation-pH gradient technique, 200 or 400 mg, 0 or 0.5, 10 or 20 ml and bath or probe sonication for A, B, C, D and E respectively. Responses measured were Particle size (PS) (nm), Zeta potential (ZP) (mV) and Entrapment efficiency percent (EE%). Ion selective electrode was used as a novel method for measuring unentrapped drug concentration and calculating entrapment efficiency without the need for liposomal separation. Factors mainly affecting the studied responses were Cholesterol: PhC ratio and hydration volume for PS, preparation technique for ZP and preparation technique and hydration volume for EE%. The applied 2 V 5-1 design enabled the use of only 16 trial combinations for screening the influence of five factors on weakly basic drugs liposomal systems. This clarifies the value of the use of screening experiments before extensive investigation of certain factors in detailed optimization studies. Copyright © 2017. Published by Elsevier B.V.

The pro-heroin effects of anti-opium laws in Asia.

Westermeyer, J

1976-09-01

Over 25 years anti-opium laws were enacted by three Asian governments in countries where opium use was traditional. Within months, heroin use suddenly appeared; and within a decade, heroin addiction surpassed opium addiction. The laws led to (1) increased price of narcotic drugs, (2) a heroin "industry," (3) corruption of the law enforcement system, and (4) major health problems involving parenteral drug use. The Asian experience indicates that antinarcotic laws can be effective only with careful preparations: (1) changing society's attitude toward the traditional drug from ambivalence to opposition; (2) mobilizing resources to treat and rehabilitate all addicts within a short period of time; (3) developing the social will to incarcerate all "recidivist" addicts for a prolonged period; and (4) preventing narcotic production or importation.

Scaffolds that secure and deliver therapeutic ingredients like signaling molecules and stem cells hold great promise for drug delivery and tissue engineering. Employing a core-shell design for scaffolds provides a promising solution. Some unique methods, such as co-concentric nozzle extrusion, microfluidics generation, and chemical confinement reactions, have been successful in producing core-shelled nano/microfibers and nano/microspheres. Signaling molecules and drugs, spatially allocated to the core and/or shell part, can be delivered in a controllable and sequential manner for optimal therapeutic effects. Stem cells can be loaded within the core part on-demand, safely protected from the environments, which ultimately affords ex vivo culture and in vivo tissue engineering. The encapsulated cells experience three-dimensional tissue-mimic microenvironments in which therapeutic molecules are secreted to the surrounding tissues through the semi-permeable shell. Tuning the material properties of the core and shell, changing the geometrical parameters, and shaping them into proper forms significantly influence the release behaviors of biomolecules and the fate of the cells. This topical issue highlights the immense usefulness of core-shell designs for the therapeutic actions of scaffolds in the delivery of signaling molecules and stem cells for tissue regeneration and disease treatment.

Rational design of dendrimer/lipid nanoassemblies in drug delivery for cancer chemotherapy

Science.gov (United States)

Sun, Qihang

Nanocarriers can minimize the side effects and improve therapeutic efficacy of anticancer drugs. Although some success has been achieved via active or passive drug delivery to tumor cells, the known nanocarriers are far from satisfying therapeutic efficacy expectations. This is because they usually fail in one of the four crucial requirements, that is, to retain drug in blood circulation but release it reliably in tumor cells and to be stealthy in transport in circulation and tumor tissue but sticky upon arrival at the tumor cell. Therefore, the goal of this work is to fabricate nanoassemblies of dendrimers and lipids to address all these challenges. Particularly, nanoassemblies designed and prepared in this work are illustrated to improve the tumor tissue penetration. Examples of dendrimers synthesized in this work are water-insoluble, pH-dependent water-insoluble and water-soluble biodegradable polyester dendrimers. These dendrimers are shown to be encapsulated by commonly used fusogenic and long-circulating lipids to form reliable nanoassemblies. The dendrimer/lipid nanocarriers are used to demonstrate a cascade drug delivery. They are expected to be stable in circulation, due to their appropriately large size, but to release the drug-loaded dendrimers in tumor tissue. The released dendrimers carrying drugs are much smaller and hence expected to have a much deeper penetration throughout the tumor tissue.

Throughout the history of human civilizations, cancer has been a major health problem. Its treatment has been interesting but challenging to scientists. Glutamic acid and its derivative glutamine are known to play interesting roles in cancer genesis, hence, it was realized that structurally variant glutamic acid derivatives may be designed and developed and, might be having antagonistic effects on cancer. The present article describes the state-of-art of glutamic acid and its derivatives as anticancer agents. Attempts have been made to explore the effectivity of drug-delivery systems based on glutamic acid for the delivery of anticancer drugs. Moreover, efforts have also been made to discuss the mechanism of action of glutamic acid derivatives as anticancer agents, clinical applications of glutamic acid derivatives, as well as recent developments and future perspectives of glutamic acid drug development have also been discussed.
