The study below is meant to focus on the migrant smuggling crime in Romania, especially analysis of the migrant smuggling infraction provided in the Romanian Criminal Code. Being a component of the human trafficking activity, the illegal migration is a phenomenon that is continuously extending and harder to stop due to the involvement of the organized crime networks and also due the ingenuousness and maliciousness of the people and the criminals. Therewith, the migrant smuggling is highly con...

Smuggling of migrants in Kosovo

Full Text Available Smuggling of migrants, as a serious type of criminality, takes an important place in legal science and criminal legislation. This is due to the fact that actions creating the image of these criminal offences also cause numerous individual, family and societal consequences. Smuggling migrants, with all its consequences, attracts the attention not only of the state authorities, but also the wider public, and numerous researchers and scholars. Nevertheless, despite this fact, this phenomenon has not been studied thoroughly. There is a dire lack of such research in recent years, specifically because of the presence of such crimes in a relatively higher number. This circumstance, specifically the fact that in Kosovo, smuggling migrants is a frequent occurrence, made me engage in studying this type of criminality. The aim of this paper is to research on criminal offences of migrant smuggling in Kosovo, and especially their causes. The causes of these criminal offences may be of numerous natures, but the main causes may be sought in social and economic circumstances, and other conditions related to the unstable political setting, weaknesses in operations of justice authorities, lack of implementation of criminal legislation, etc. In researching the criminal offences of smuggling migrants, I have used the method of historical materialism, legal-dogmatic method, statistical method, complaint method and interviews, and the method of studying individual cases. In the case of addressing criminal offences of smuggling migrants, I have concluded that these offences represent a serious type of crime, thereby resulting in dire individual, family and societal consequences. They are found in all modern societies, including Kosovo.

Plutonium again (smuggling and movements)

A link is discounted between nuclear proliferation and the recently discovered smuggled plutonium from the former Soviet Union at Munich airport and other places in Germany. It is argued that governments wishing to obtain nuclear materials to develop a weapons programme would not arrange to have it smuggled in a suitcase. Instead, it is speculated that a link exists between the plutonium smuggling incidents and the desire to promote the production of mixed oxide (MOX) fuel. Such incidents, by further raising public anxiety, may be intended to turn public opinion in favour of MOX fuel production as a sensible way of getting rid of surplus plutonium. (UK)

Human smuggling in Austria: a comparative analysis of data on smuggled migrants from former Yugoslavia and the Russian Federation.

Peterka-Benton, Daniela

2011-01-01

This article provides a summary of the author’s research on human smuggling in Austria comparing migrants from Former Yugoslavia and the Russian Federation. The project’s primary intent was to collect more detailed information on migrants seeking asylum in Austria and their use of smuggling services to leave their home countries, including detailed information on demographics, force or threat of force by smugglers, routes and methods of transportation, costs of smuggling, payment methods, and deeper perceptual questions regarding the flight. Another central premise of the article discusses how current distinctions between human smuggling and human trafficking are arbitrary in many regards.

The behaviour of purchasing smuggled cigarettes in Taiwan.

Since market liberalization in 1987, the Taiwan Tobacco and Wine Monopoly Bureau (TTWMB) annual statistics indicate that both the demand for imported cigarettes as well as the number of seized smuggled packs have increased with an average revenue loss of NT dollars 4942 million over the past 15 years. The NT dollars 10 average increase in cigarette prices after Taiwan entered the World Trade Organization (WTO) and the implementation of the Tobacco and Alcohol Tax Law in 2002 are forcing policy makers to examine smuggling even more closely. This study evaluates factors that affect an individual smoker's decision to purchase smuggled cigarettes, particularly when faced with higher prices. 437 male smokers of imported cigarettes were drawn from a national interview survey on cigarette consumption, which the Division of Health Policy Research at the National Health Research Institutes conducted during the year 2000. Multiple logistic regression models were used to analyse the behaviour of purchasing smuggled cigarettes with respect to demographic factors, economic factors, smoking behaviour, and other variables. Cigarette price was the driving factor most closely linked to the purchase of smuggled cigarettes--a 1% increase in cigarette price raised the likelihood of purchasing smuggled cigarettes at least 2.60 times (95% confidence interval (CI) 1.08 to 6.26). Smokers who spent more than NT 1000/month dollars on cigarettes were twice as likely to purchase smuggled cigarettes as those who spent less than NT 1000 dollars (odds ratio (OR) 2.34, 95% CI 1.48 to 3.70). Betel nut chewers were more likely to purchase smuggled cigarettes (OR 1.80, 95% CI 1.09 to 2.90). Smokers who opposed cigarette taxation policy were 1.69 times more likely to buy smuggled cigarettes. Personal income was not significantly associated with smuggled cigarettes purchases. This study evaluates what causes smokers to purchase smuggled cigarettes. We have determined that cigarette price is the most

Cigarette smuggling in Europe: who really benefits?

Cigarette smuggling, now on the increase, is so widespread and well organised that it poses a serious threat to public health. This threat comes from two principal directions. First, smuggling makes cigarettes available cheaply, thereby increasing consumption. A third of annual global exports go to the contraband market, representing an enormous impact on consumption, and thus causing an increase in the burden of disease, especially in poorer countries. It is also costing government treasuries thousands of millions of dollars in lost tax revenue. Second, the tobacco industry uses smuggling politically, lobbying governments to lower tax, arguing that smuggling is caused by price differences. This paper shows that the claimed correlation between high prices and high levels of smuggling does not exist in western Europe. In fact, countries such as Norway and Sweden, with expensive cigarettes, do not have a large smuggling problem, whereas countries in the south of Europe do. Cigarette smuggling is not caused principally by "market forces". It is mainly caused by fraud, by the illegal evasion of import duty. The cigarettes involved are not the cheap brands from southern European countries, for which there is no international market. It is the well-known international brands such as Marlboro and Winston. We propose much tighter regulation of cigarette trade, including an international transport convention, and a total ban on transit trade-sale by the manufacturers to dealers, who sell on to smugglers.

Real threat of nuclear smuggling

International Nuclear Information System (INIS)

Williams, P.; Woessner, P.N.

1996-01-01

Trade in uranium and plutonium during the past five years has given smuggling unprecedented relevance to international security. Yet there is considerable controversy over the threat nuclear smuggling poses. Even though serious efforts are being made to attack the problem at the source, the international community has been slow to respond to the dangers that nuclear smuggling presents. We suggest that systematic multinational measures be taken as soon as possible to inhibit theft at the source, to disrupt trafficking and to deter buyers. The U.S., Germany, Russia and other nations with an interest in the nuclear problem should set up a 'flying squad' with an investigative arm, facilities for counter terrorist and counter extortion actions and a disaster management team. This paper discusses these issues. 3 refs

Turning off the tap: the real solution to cigarette smuggling.

Science.gov (United States)

Joossens, L; Raw, M

2003-03-01

The tobacco industry has argued that tobacco smuggling is caused by market forces, i.e., by the price differences between countries, which create an incentive to smuggle cigarettes from 'cheaper' to 'more expensive' countries, and so urged governments to solve the problem by reducing taxes to remove this differential, which will also, they say, restore revenue. Although such market forces have some effect, smuggling is in fact more prevalent in 'cheaper' countries, and reducing tax is not the solution. Where taxes have been reduced tobacco consumption has risen and revenue has fallen, with disastrous consequences for public health. The key to understanding cigarette smuggling is understanding the role of the tobacco industry. At the heart of cigarette smuggling is large scale fraud: container loads of cigarettes are exported, legally and duty unpaid, to countries where they have no market, and where they disappear into the contraband market. They are often smuggled back into the country of origin, where they are sold at a third to half price. It is therefore profitable because duty has been illegally evaded. The key to controlling cigarette smuggling is not lowering taxes, it is controlling the tobacco manufacturing industry and its exporting practices.

State and Smuggling in Modern China: The Case of Guangzhouwan/Zhanjiang

Directory of Open Access Journals (Sweden)

Steven Pieragastini

2017-12-01

Full Text Available The Leizhou Peninsula in western Guangdong (concurrent with the present-day municipality of Zhanjiang has at several points in history been an important site of exchange, both licit and illicit in the eyes of central authorities. The French gained control of the area from the weakened Qing government in 1898–1899 and established their “leased territory” of Guangzhouwan. Administered as part of French Indochina, Guangzhouwan became a fiefdom of smugglers, pimps, and pirates, never developing into the rival to Hong Kong that the French hoped it would become. After a brief Japanese occupation, the French returned the leased territory to the government of Chiang Kai-shek (Jiang Jieshi after World War II, but their colonial presence left a legacy of trafficking, violence, and anti-imperialism that emboldened Communist guerrillas in the area. Once the Communists came into power in 1949, they subjected Zhanjiang and other liminal spaces along the Chinese coast to vigorous anti-smuggling and anti-drug campaigns. But a return to smuggling in the Reform Era (1978–present suggests that the successful repression of smuggling in the Mao era may have been a temporary exception to the historical rule in this region.

This article demonstrates the potential of an historical archaeology of smuggling and the value of an interdisciplinary approach to the study of smuggling and its prevention. By exploring the previously unstudied history of the King’s Pipe in Falmouth, a large chimney used for the destruction of tobacco, a rare survivor of many that once existed in England’s port cities, it demonstrates that archaeology could transform our understanding of smuggling and its prevention, and more broadly the history of crime and punishment in eighteenth century England.

Nuclear Smuggling and Threats to Lithuanian Security

Directory of Open Access Journals (Sweden)

Murauskaitė Eglė

2016-12-01

Full Text Available The article explores threats related to illicit trafficking of radioactive materials and dual-use goods applicable in state level nuclear programs, actualizing the global trends for the Baltic region. The article points to Eastern Europe’s changing risk profile in this respect, as increasing penetration of Russian criminal groups inside Ukraine and the destabilized situations in neighboring countries create an environment where the risk of nuclear smuggling is on the rise. Criminal entities can be seen forming new bonds, with trafficking routes intersecting and zones of influence shifting - consequently, an unusual level of criminal involvement in nuclear smuggling is observed, alongside a geographic shift of smuggling patterns. In addition, states seeking materials and technologies for their military programs have taken a notable interest in this region as a way of circumventing international transit regulations. The article looks at the likely implications of these new nuclear smuggling trends for the security of the Baltic states. It suggests that Lithuania may soon be facing a relatively new threat, and one that it is ill-prepared to counter. The article discusses the risk factors and indicators to watch before that risk becomes reality, and offers ways for Lithuania to contribute to addressing these increasingly acute problems on a regional level.

Background Iran is one of two main target markets for tobacco smuggling in the WHO's Eastern Mediterranean Region. The Iranian government has a local tobacco monopoly but there is high demand for international brands. Informal reports show about 20% of cigarette consumption is smuggled brands. This pack survey study is the first in Iran to gather validated information on use of smuggled cigarettes. Methods A randomized cross-sectional household survey in Tehran in 2008–2009 of 1540 smokers aged 16–90 (83% men) was performed, including interviewer checking of cigarette packs. Results In all, 20.9% of cigarettes and 6.7% of domestic branded cigarettes were smuggled. A total of 60.1% of smokers preferred foreign cigarettes. There was no significant difference between consumption of illegal cigarettes by sex. (Fisher exact test p=0.61) Use of smuggled cigarettes was higher among younger smokers (p=0.01) Conclusions Use of illegal cigarettes is high. Tobacco control laws outlawing their sale are not being enforced. PMID:20876076

Agony of the ecstasy: report of five cases of MDMA smuggling.

Low, V H S; Dillon, E K

2005-10-01

The international smuggling of illicit drugs by the ingestion or rectal insertion of drug-filled packages is recognized in the trafficking of heroin and cocaine. Customs authorities, with suspicion of such activities, presented five subjects. The legally allowed radiological examination comprising one supine abdominal radiograph was performed. Radiographic findings demonstrated the presence of multiple enteric oval, capsule-shaped packages of soft tissue density. This was confirmed following supervised evacuation of bowel contents induced by the administration of laxatives. Analysis of the concealed material identified ecstasy (methylenedioxymethamphetamine (MDMA)), a substance not previously reported as transported by this route.

Validation of a BOTDR-based system for the detection of smuggling tunnels

Cross-border smuggling tunnels enable unmonitored movement of people, drugs and weapons and pose a very serious threat to homeland security. Recently, Klar and Linker (2009) [SPIE paper No. 731603] presented an analytical study of the feasibility of a Brillouin Optical Time Domain Reflectometry (BOTDR) based system for the detection of small sized smuggling tunnels. The current study extends this work by validating the analytical models against real strain measurements in soil obtained from small scale experiments in a geotechnical centrifuge. The soil strains were obtained using an image analysis method that tracked the displacement of discrete patches of soil through a sequence of digital images of the soil around the tunnel during the centrifuge test. The results of the present study are in agreement with those of a previous study which was based on synthetic signals generated using empirical and analytical models from the literature.

Smuggling and cross border shopping of tobacco in Europe.

Science.gov (United States)

Joossens, L; Raw, M

1995-05-27

Governments have recently become concerned about cross border shopping and smuggling because it can decrease tax revenue. The tobacco industry predicted that, with the removal of border controls in the European Union, price differences between neighbouring countries would lead to a diversion of tobacco trade, legally and illegally, to countries with cheaper cigarettes. According to them this diversion would be through increased cross border shopping for personal consumption or through increased smuggling of cheap cigarettes from countries with low tax to countries with high tax, where cigarettes are more expensive. These arguments have been used to urge governments not to increase tax on tobacco products. The evidence suggests, however, that cross border shopping is not yet a problem in Europe and that smuggling is not of cheap cigarettes to expensive countries. Instead, more expensive "international" brands are smuggled into northern Europe and sold illegally on the streets of the cheaper countries of southern Europe.

Training options for countering nuclear smuggling

International Nuclear Information System (INIS)

Ball, D Y; Erickson, S A

1999-01-01

The burden of stopping a nuclear smuggling attempt at the border rests most heavily on the front-line customs inspector. He needs to know how to use the technological tools at his disposal, how to discern tell-tale anomalies in export documents and manifests, how to notice psychological signs of a smuggler's tension, and how to search anything that might hide nuclear material. This means that assistance in the counter-nuclear smuggling training of customs officers is one of the most critical areas of help that the United States can provide. This paper discusses the various modes of specialized training, both in the field and in courses, as well as the types of assistance that can be provided. Training for nuclear customs specialists, and supervisors and managers of nuclear smuggling detection systems is also important, and differs from front-line inspector training in several aspects. The limitations of training and technological tools such as expert centers that will overcome these limitations are also discussed. Training assistance planned by DOE/NN-43 to Russia within the Second Line of Defense program is discussed in the light of these options, and future possibilities for such training are projected

Blood cigarettes: cigarette smuggling and war economies in central and eastern Africa.

Science.gov (United States)

Titeca, Kristof; Joossens, Luk; Raw, Martin

2011-05-01

To analyse cigarette smuggling practices in central and eastern Africa. Primary data were gathered during long-term qualitative field research in which about 400 interviews were conducted. Analysis of secondary sources included academic literature and reports from non-government organisations, multilateral organisations and the press. Our research suggests that the following factors play an important role in cigarette smuggling in eastern and central Africa: (1) government officials encounter difficulties monitoring the long and porous borders; (2) there is a general problem of corrupt government officials and particularly those who allow large-scale smugglers to operate; (3) criminal elements also play an important role in smuggling--cigarette smuggling has helped rebel groups to finance their activities, something illustrated through examples from the war economy in the eastern part of the Democratic Republic of Congo. Our research suggests that cigarette smuggling in this region is not primarily the result of different taxation levels in neighbouring states, but rather the outcome of weak state capacity, high levels of corruption and the activities of rebel groups. Under these conditions smuggling cigarettes becomes an attractive option as taxation is so easily avoided. This explains why in the low-income countries in this study there are high levels of smuggling in spite of low cigarette prices. Comprehensive supply control and enforcement legislation, and cooperation at national, regional and global level are needed to tackle fraudulent practices facilitated by corruption at state level, and to effectively punish interaction between cigarette traders and rebel groups.

Square, D

Four years ago the tobacco-smuggling situation was so bad that the federal government reduced its tobacco taxes. All provinces in the East save Newfoundland followed suit by lowering provincial taxes as well. The western provinces adamantly refused to do this. Today, cartons of cigarettes that sell for $26 in Ontario cost roughly $45 west of the Ontario border. The result, says David Square, is that tobacco smuggling is now a thriving industry in western Canada.

Identifying Victims of Human Trafficking at Hotspots by Focusing on People Smuggled to Europe

Directory of Open Access Journals (Sweden)

Matilde Ventrella

2017-06-01

Full Text Available Research has shown that smuggling of migrants is associated with human trafficking. Hence, victims of human trafficking amongst smuggled migrants should be identified by EU Member States at hotspots established by the European Commission, to overcome the migrant and refugee crisis. Identified victims should be given a visa and a programme of protection to escape their traffickers. In order to achieve these objectives, research suggests that EU law on migrant smuggling should be amended and the Temporary Protection Directive should be applied to smuggled persons when there is an indication that they may be victims of human trafficking. This approach should be adopted by the EASO in cooperation with police forces investigating smuggling and trafficking at hotspots.

2001-01-01

Full text: Background: Fueled by an increase in intercepted nuclear smuggling events, the threat of nuclear smuggling has received increased attention in recent years. This attention has resulted in a focused effort to improve the ability to deter or detect smuggling attempts through border crossings, including seaports, airports, and rail and road crossings. These efforts have primarily been focused on installing SNM detectors across vehicle and pedestrian gates entering these ports. However, the effectiveness of this application in deterring or detecting events has not been carefully evaluated. A recent effort was undertaken to evaluate in detail the susceptibility of an international seaport and airport to nuclear smuggling. The evaluation considered a range of adversary profiles to match these against existing and proposed port security measures and equipment. The evaluation was pursued using path analysis methodologies, which were adapted to the port environment. As a result of limited data concerning the effectiveness of patrol, search, and access control procedures at the port, an assessment methodology was developed to estimate these in a standardized fashion. The methodology considers a detailed list of tasks each type of adversary must successfully accomplish for any particular smuggling scenario and path through the port. Within these tasks, locations or times of potential detection are identified. From a look-up table, a detection level (Low, Medium, or High) is assigned to each detection potential based upon the type of detection possible and considering the possible access or authority of each adversary. The overall detection potential in determined as a sum of these individual detection potentials according to the equation: P t ={1-Σ(1-P n ). Where: P t is the total detection potential for an adversary path, and P n is the individual detection at a particular location or time. The evaluation revealed that the current process of installing portals at

Cigarette smuggling is a major public health issue, stimulating increased tobacco consumption and undermining tobacco control measures. China is the ultimate prize among tobacco's emerging markets, and is also believed to have the world's largest cigarette smuggling problem. Previous work has demonstrated the complicity of British American Tobacco (BAT) in this illicit trade within Asia and the former Soviet Union. This paper analyses internal documents of BAT available on site from the Guildford Depository and online from the BAT Document Archive. Documents dating from the early 1900s to 2003 were searched and indexed on a specially designed project database to enable the construction of an historical narrative. Document analysis incorporated several validation techniques within a hermeneutic process. This paper describes the huge scale of this illicit trade in China, amounting to billions of (United States) dollars in sales, and the key supply routes by which it has been conducted. It examines BAT's efforts to optimise earnings by restructuring operations, and controlling the supply chain and pricing of smuggled cigarettes. Our research shows that smuggling has been strategically critical to BAT's ongoing efforts to penetrate the Chinese market, and to its overall goal to become the leading company within an increasingly global industry. These findings support the need for concerted efforts to strengthen global collaboration to combat cigarette smuggling.

Decision-based model development for nuclear material theft, smuggling, and illicit use

International Nuclear Information System (INIS)

Scott, B.

2002-01-01

Full text: Nuclear material is vulnerable to a range of theft, sabotage, smuggling and illicit use scenarios. These scenarios are dependent on the choices of individuals and organizations involved in these activities. These choices, in turn; are dependent on the perceived payoff vectors of the involved players. These payoff vectors can include monetary gain, ability to avoid detection, penalties for detection, difficulty of accomplishment, resource constraints, infrastructure support, etc. Threat scenarios can be developed from these individual choices, and the set of worst-case threat scenarios can be compiled into a threat definition. The implementation of physical protection controls is dependent on the developed threat scenarios. The analysis of the composition of the postulated threat can be based on the analysis of the postulated decisions of the individuals and organizations involved on theft, smuggling, and illicit use. This paper proposes a model to systematically analyze the significant decision points that an individual or organization addresses as result of its goals. The model's dependence on assumptions is discussed. Using these assumptions, a model is developed that assigns probabilities to a set of decisions performed by the individuals involved in theft/smuggling. The individual and organisation's decisions are based on the perceived cost/benefit of the decisions and the resource constraints. Methods for functionally obtaining decision probabilities from perceived cost/benefit are proposed. The treatment of high-consequence/low-probability events is discussed in terms of analysis of precursor events, and the use of sensitivity analysis is discussed. An example of a simplified model for nuclear material theft, smuggling, and illicit use is presented, and the results of this simplified model are evaluated. By attempting to model the potential distribution of nuclear material theft/smuggling events, this model increases the analytical tools available

We report the results of Raman measurements on some common military explosives and explosives precursors deposited on clothing fabrics, both synthetic and natural, in concentration comparable to those obtained from a single fingerprint or mixed with similar harmless substances to detect illegal compounds for smuggling activities. Raman spectra were obtained using an integrated portable Raman system equipped with an optical microscope and a 785-nm laser in an analysis of smuggling purposes or for counterfeiting activities.

In search of a missing link: Nuclear terrorism and nuclear smuggling

International Nuclear Information System (INIS)

Gere, F.

1998-01-01

There is a common assumption that because of the development of a nuclear smuggling (NS) generated by the disintegration of the Soviet Union, nuclear terrorism (NT) becomes a clear and present danger. But the analysis of the trends in smuggling as well as the current and foreseeable strategies of terrorist organizations suggest that the two phenomena have little chance to connect. Nevertheless it is necessary to understand why there is so much concern about such a possibility. (author)

Complicity in contraband: British American Tobacco and cigarette smuggling in Asia.

To examine the complicity of British American Tobacco (BAT) in cigarette smuggling in Asia, and to assess the centrality of illicit trade to regional corporate strategy. Analysis of previously confidential documents from BAT's Guildford depository. An iterative strategy combined searches based on geography, organisational structure, and key personnel, while corporate euphemisms for contraband were identified by triangulation. BAT documents demonstrate the strategic importance of smuggling across global, regional, national, and local levels. Particularly important in Asia, contraband enabled access to closed markets, created pressure for market opening, and was highly profitable. Documents demonstrate BAT's detailed oversight of illicit trade, seeking to reconcile the conflicting demands of control and deniability. BAT documents demonstrate that smuggling has been driven by corporate objectives, indicate national measures by which the problem can be addressed, and highlight the importance of a coordinated global response via WHO's Framework Convention on Tobacco Control.

Body-packing is the way of psychoactive substances smuggling by swallowing of carefully prepared packages with drugs into the gastrointestinal tract or by insertion them into the vagina or the rectum, especially in order to avoid finding them by the custom service. Cocaine, as well as opiates, is the one of the most often smuggled drugs by so called body-packers. In the present study the first case of the body-packer from Malopolska region in Poland, who was observed in the Toxicology Department of the Collegium Medicum UJ, was described. The 29-year-old man swallowed 60 packages containing cocaine with a total net weight of about 500 grams. The plain abdominal radiography revealed multiple shadows of foreign bodies in the gastrointestinal tract, but the results of blood and urine cocaine measurements were negative. During the 37-hours stay in our department the patient was monitored (blood pressure, heart rate, temperature), laxatives and oral fluids were administered. All the packages were evacuated through the natural way and it was followed up by the control abdominal radiography. No symptoms of acute cocaine intoxication or any other complications were observed. According to the case there is also the thorough review of literature presented including the kinds of body-packing, the diagnostic methods used in recognizing of body-packers and the ways of their treatment taking into consideration the conservative management as well as surgical methods.

Trafficking and Syrian Refugee Smuggling: Evidence from the Balkan Route

Directory of Open Access Journals (Sweden)

Danilo Mandic

2017-06-01

Full Text Available As of March 2016, 4.8 million Syrian refugees were scattered in two dozen countries by the civil war. Refugee smuggling has been a major catalyst of human trafficking in the Middle East and Europe migrant crises. Data on the extent to which smuggling devolved into trafficking in this refugee wave is, however, scarce. This article investigates how Syrian refugees interact with smugglers, shedding light on how human smuggling and human trafficking interrelated on the Balkan Route. I rely on original evidence from in-depth interviews (n = 123 and surveys (n = 100 with Syrian refugees in Jordan, Turkey, Greece, Serbia, and Germany; as well as ethnographic observations in thirty-five refugee camps or other sites in these countries. I argue that most smugglers functioned as guides, informants, and allies in understudied ways—thus refugee perceptions diverge dramatically from government policy assumptions. I conclude with a recommendation for a targeted advice policy that would acknowledge the reality of migrant-smuggler relations, and more effectively curb trafficking instead of endangering refugees.

Detecting nuclear materials smuggling: performance evaluation of container inspection policies.

Gaukler, Gary M; Li, Chenhua; Ding, Yu; Chirayath, Sunil S

2012-03-01

In recent years, the United States, along with many other countries, has significantly increased its detection and defense mechanisms against terrorist attacks. A potential attack with a nuclear weapon, using nuclear materials smuggled into the country, has been identified as a particularly grave threat. The system for detecting illicit nuclear materials that is currently in place at U.S. ports of entry relies heavily on passive radiation detectors and a risk-scoring approach using the automated targeting system (ATS). In this article we analyze this existing inspection system and demonstrate its performance for several smuggling scenarios. We provide evidence that the current inspection system is inherently incapable of reliably detecting sophisticated smuggling attempts that use small quantities of well-shielded nuclear material. To counter the weaknesses of the current ATS-based inspection system, we propose two new inspection systems: the hardness control system (HCS) and the hybrid inspection system (HYB). The HCS uses radiography information to classify incoming containers based on their cargo content into "hard" or "soft" containers, which then go through different inspection treatment. The HYB combines the radiography information with the intelligence information from the ATS. We compare and contrast the relative performance of these two new inspection systems with the existing ATS-based system. Our studies indicate that the HCS and HYB policies outperform the ATS-based policy for a wide range of realistic smuggling scenarios. We also examine the impact of changes in adversary behavior on the new inspection systems and find that they effectively preclude strategic gaming behavior of the adversary. © 2011 Society for Risk Analysis.

Change in tobacco excise policy in Bulgaria: the role of tobacco industry lobbying and smuggling.

2014-05-01

To examine how transnational tobacco companies (TTCs) tried to penetrate the Bulgarian cigarette market and influence tobacco excise tax policy after the fall of communism and during Bulgaria's accession to the European Union (EU). Analysis of internal tobacco industry documents supplemented by analysis of press coverage, tobacco industry journals, market reports and key informant interviews. TTCs have been involved in cigarette smuggling to and through Bulgaria since at least 1975 and used smuggling as a market-entry strategy. National tobacco company Bulgartabac appears to have been involved in smuggling its own cigarettes from and reimporting them to Bulgaria. Since Bulgaria's accession to the EU opened the market to the TTCs, TTCs have exaggerated the scale of the illicit trade to successfully convince politicians and public health experts that tax increases lead to cigarette smuggling. Yet, sources point to TTCs' continued complicity in cigarette smuggling to and through Bulgaria between 2000 and 2010. TTCs aimed to influence the Bulgarian tobacco excise tax regime, import duties and pricing mechanism, but appear to have been less successful than in other former communist countries in part due to the co-existence of a state-owned tobacco company. Undisclosed meetings between the tobacco industry and government ministers and officials are ongoing despite Bulgaria being a party to the Framework Convention on Tobacco Control (FCTC). The TTCs continued involvement in smuggling suggests that deals in 2004, 2007 and 2010 which the European Commission has reached with TTCs to address cigarette smuggling are inadequate. The TTCs' continued access to policymakers suggests that the FCTC is not being properly implemented. Published by the BMJ Publishing Group Limited.

2009-01-01

Much of the data that is collected and analyzed today is structural, consisting not only of entities but also of relationships between the entities. As a result, analysis applications rely upon automated structural data mining approaches to find patterns and concepts of interest. This ability to analyze structural data has become a particular challenge in many security-related domains. In these domains, focusing on the relationships between entities in the data is critical to detect important underlying patterns. In this study we apply structural data mining techniques to automate analysis of nuclear smuggling data. In particular, we choose to model the data as a graph and use graph-based relational learning to identify patterns and concepts of interest in the data. In this paper, we identify the analysis questions that are of importance to security analysts and describe the knowledge representation and data mining approach that we adopt for this challenge. We analyze the results using the Russian nuclear smuggling event database.

Gauvin, Louis

2005-01-01

"Cigarette smuggling: a wide scope phenomenon only there to serve the interests of big tobacco manuafacturers" uses industry officials' quotes and documents to describe how tobacco manufacturers are involved in the organisation of smuggling and how manufacturers use smuggling in two ways: on one hand, to flood markets with cheap cigarettes and defeat governements' efforts to reduce tobacco consumption by adopting one of the most efficient public health measures (ie: high taxation of tobacco products) and on the other hand, by using the false threat of increased contraband to scare politicians and prevent them from adopting strong fiscal policies. The Framework Convention on Tobacco Control (FCTC) with a protocol on smuggling and the collaboration between international agencies is a means to counter and defeat the tobacco industry attemps at sabotaging efficient public health measures.

Detector Requirements to Curb Nuclear Smuggling

International Nuclear Information System (INIS)

Erickson, S A

2001-01-01

The problem of stopping nuclear smuggling of terrorist nuclear devices is a complex one, owing to the variety of pathways by which such a device can be transported. To fashion new detection systems that improve the chances of detecting such a device, it is important to know the various requirements and conditions that would be imposed on them by both the types of devices that might be smuggled and by the requirement that it not overly interfere with the transportation of legitimate goods. Requirements vary greatly from low-volume border crossings to high-volume industrial container ports, and the design of systems for them is likely to be quite different. There is also a further need to detect these devices if they are brought into a country via illicit routes, i.e., those which do not pass through customs posts, but travel overland though open space or to a smaller, unguarded airport or seaport. This paper describes some generic uses of detectors, how they need to be integrated into customs or other law enforcement systems, and what the specifications for such detectors might be

Objective: Drug smuggling in the gastrointestinal tract has soared within the last 20 years. Though illegal substances in the gastrointestinal tract can be visualized with ultrasound, MRI and CT, the abdominal radiograph has by far remained the most frequently used way of detecting smuggled drugs. The purpose of the study was to evaluate the inter-radiologist interpretation error and the reliability of the abdominal radiograph in detecting smuggled drugs. Materials and methods: A total of 279 abdominal radiographs of suspected smugglers were classified by three radiologists as clearly positive or negative for drug smuggling. All available information about the cases was collected from the customs officers and police. Results: Out of these cases 203 (73%) were interpreted as negative and 35 (13%) as positive by all three radiologists. In 86% of the cases there was, therefore, an inter-radiological agreement in interpreting the images. In 41 (14%) cases, however, there was an inter-radiologist disagreement. Kappa-value for inter-observer variability was 0.70. Conclusions: In up to a seventh of the abdominal radiographs the interpretation can be challenging even for an experienced radiologist. False positive interpretation can lead to innocent passengers being detained in vain. As negatively interpreted images usually result in releasing of the suspect, there is no way of knowing how many false negative occur. This makes the abdominal radiograph a suboptimal examination, and low dose CT should be considered as the screening modality for gastrointestinal drug smugglers

Progress in combating cigarette smuggling: controlling the supply chain.

Science.gov (United States)

Joossens, L; Raw, M

2008-12-01

The illicit tobacco trade results in huge losses of revenue to governments, estimated at $US40-50 billion in 2006, and in increased consumption and thus health problems because it makes tobacco available more cheaply. On 20 October 2008 the second meeting of the International Negotiating Body (INB2) on the illicit trade protocol of WHO's Framework Convention on Tobacco Control (FCTC) will discuss measures to tackle the illicit trade in tobacco products. This paper presents the experience over the last decade of three countries, Italy, Spain and the United Kingdom, which shows that tobacco smuggling can be successfully tackled. The evidence strongly suggests that the key to controlling smuggling is controlling the supply chain, and that the supply chain is controlled to a great extent by the tobacco industry.

Managing Migration: Is border control fundamental to anti-trafficking and anti- smuggling interventions?

Directory of Open Access Journals (Sweden)

Rebecca Miller

2013-09-01

Full Text Available Over the last several decades, globalisation and a growing concern over security issues, including transnational crime and terrorism, has shaped migration policies and the priorities of states. As migration rose to the top of many government agendas, a rapid tightening and regularisation of borders ensued in an attempt to keep undesirable, high-risk migrants out of potential destination countries. Concomitantly, transnational crimes, such as trafficking in persons and the smuggling of migrants, have been increasingly defined as border security problems. This article examines the extent to which border control is fundamental to anti-trafficking and anti-smuggling interventions, situating the debate within the wider nexus of globalisation and the securitisation of migration. Based upon their work with the United Nations Office on Drugs and Crime (UNODC Regional Centre for Southeast Asia and the Pacific, the authors take the standpoint that given it is the sovereign right of each state to control its border and regulate migration, the human rights of migrants must be considered within this realpolitik. Clearly, though, this claim is highly political and contentious. In the article, we explore some of the tensions and contradictions that have emerged in this debate, and then develop an argument to suggest that it is possible for states to combine managed migration and strict border controls with the protection of human rights in the current context of globalisation.

Body pushing, prescription drugs and hospital admission.

Science.gov (United States)

Byard, Roger W; Kenneally, Michaela

2017-09-01

A 39-year-old man died of multi-organ failure complicating mixed drug toxicity that included methadone, oxazepam, oxycodone and nitrazepam. His past medical history involved alcohol and poly-substance abuse with chronic self-harm and suicidal ideation. There had been multiple hospital admissions for drug overdoses. At autopsy the most unusual finding was of two packages of 10 tablets each, wrapped in thin plastic film within the rectum. The insertion of drugs into body orifices and cavities has been termed body pushing to distinguish it from body packing where illicit drugs are wrapped and swallowed for transport and smuggling, and body stuffing where small amounts of loosely wrapped or unwrapped drugs are swallowed to conceal evidence from police. This case demonstrates that body pushing may not always involve illicit drugs or attempted concealment from police or customs officials. It appears that the drugs had been hidden to ensure an additional supply during the time of residence in hospital. The extent to which body pushing is currently being used by patients to smuggle drugs into secure medical facilities is yet to be determined.

Estimating price elasticities when there is smuggling: the sensitivity of smoking to price in Canada.

Science.gov (United States)

Gruber, Jonathan; Sen, Anindya; Stabile, Mark

2003-09-01

A central parameter for evaluating tax policies is the price elasticity of demand for cigarettes. But in many countries this parameter is difficult to estimate reliably due to widespread smuggling, which significantly biases estimates using legal sales data. An excellent example is Canada, where widespread smuggling in the early 1990s, in response to large tax increases, biases upwards the response of legal cigarette sales to price. We surmount this problem through two approaches: excluding the provinces and years where smuggling was greatest; and using household level expenditure data on smoking. These two approaches yield a tightly estimated elasticity in the range of -0.45 to -0.47. We also show that the sensitivity of smoking to price is much larger among lower income Canadians. In the context of recent behavioral models of smoking, whereby higher taxes reduce unwanted smoking among price sensitive populations, this finding suggests that cigarette taxes may not be as regressive as previously suggested. Finally, we show that price increases on cigarettes do not increase, and may actually decrease, consumption of alcohol; as a result, smuggling of cigarettes may have raised consumption of alcohol as well.

Alien smuggling: East to West.

Science.gov (United States)

Walsh, J H

1987-01-01

This year untold millions of illegal aliens will enter Western Europe, Canada, and the US; in 1986, the US alone made 1.7 million apprehensions. Because of the numbers involved and the hard currency exchanged, alien smuggling has become big business--a lucrative track in desparate human beings. West Germany's open door asylum policy has been a boon to the smugglers, and West Berlin is currently a favored port of entry. The government provides social benefits--apartments, food, a stipend, and clothing--for asylum seekers. Smuggling operations appear to fit 3 categories: 1) state-sponsored alien smugglers, with a sub-category of terrorists; 2) ethnic smugglers with a history of terrorist spinoffs; and 3) independent smugglers, who are profit oriented, and willing to handle ethnic aliens and terrorists. In West Germany, immigration investigations begin at the border. West German officials often know that as they cause the Eastern border to be tightened, the flow will gravitate south toward Austria. Redirecting the trasit of Third Worlders from East Berlin away from West Germany, Sweden, and Denmark will be a stop-gap measure at best. Part of West Germany's immigration problem can be traced to the Basic Law that provides asylum for those who claim persecution (political, racial, ethnic, or religious). Yet, any attempt to change asylum would result in an admission of defeat in the quest for a unified Germany. Should Austria move to tighten its immigration laws, agreements similar to those between East and West Germany will likely follow.

Meskipun mereka harus rela membayar mahal, cara penyelundupan manusia kerap mereka gunakan karena cara formal untuk bisa masuk ke negara lain tidak dimungkinkan. Tindakan penyelundupan manusia adalah tindak pidana dalam Smuggling Protocol di mana negara-negara yang disinggahi pengungsi Rohingya seperti Thailand, Bangladesh, bahkan Indonesia telah menjadi negara pihak. Akibatnya, Pemerintah Thailand dan Bangladesh kerap menangkap pengungsi Rohingya yang masuk ke negaranya bahkan mengusir mereka untuk kembali ke Myanmar. Padahal, sebagai pencari suaka yang terancam persekusi, etnis Rohingya dilindungi oleh hukum Hak Asasi Manusia khususnya prinsip non-refoulement. Artikel ini menganalisa dilema antara aturan Smuggling Protokol yang bertujuan mencegah dan menegakan hukum atas terjadinya kejahatan penyelundupan manusia dengan kewajiban memberikan pengaman untuk melindungi hak-hak para pengungsi yang terancam persekusi.

[The scale of border trade, tax-free import and tobacco smuggling to Norway].

Science.gov (United States)

Lund, Karl Erik

2004-01-08

There are no studies of the relative significance in Norway of registered sales, tax-free import, border trade or smuggling of tobacco. The estimated registered sales of tobacco are based on data from the Norwegian customs and excise authorities. The border trade and tax-free import estimates were based on nation-wide, representative surveys of daily smokers aged 16-74 carried out by Statistics Norway for the years 1990-1993 and 1997-2001. There are no detailed data on the scale of smuggling other than confiscation statistics compiled by the customs and excise authorities. It is assumed that confiscations amount to about a tenth of the total amount smuggled into the country. The unregistered consumption of cigarettes and tobacco has been on the rise since the early 1990s; in the years 1997-2001 it accounted for about a quarter of total consumption. Broken down, the figures are as follows: 11% was purchased in Sweden, 5% in Denmark, 9% in other foreign countries; 1% was smuggled into the country. The rise in unregistered tobacco consumption is putting further pressure on the high Norwegian taxes on tobacco. But if taxes were cut, domestic demand would rise, and hence have little or even negative impact on revenue flowing to the government from the legal tobacco market and probably little impact on the levels of imported tobacco through tax-free arrangements or cross-border trade. Hence, although the price gap between Norway and neighbouring countries narrows, we must assume that the motivation to acquire tobacco will remain unaffected while Norwegians continue to travel to Sweden to stock up on inexpensive meat produce.

The gastrointestinal tract is being used to an increasing extent as a route for smuggling narcotics. Small, swallowed packages overwrapped with condoms or other materials are usually not detected by the customs authorities. Conventional abdominal radiography may indicate foreign bodies surrounded by a characteristic thin layer of gas and located in the gastrointestinal tract. Some short case histories, and the radiologic findings in four heroin 'body packers' are presented. (orig.)

Smuggling of radioactive substances. Swedish capacity to detect and analyze; Smuggling av radioaktivt material. Sveriges foermaaga till detektion och analys

Energy Technology Data Exchange (ETDEWEB)

Ringbom, A.; Spjuth, L. [Swedish Defence Research Agency (FOI), Stockholm (Sweden)

2001-04-01

This report is the result of a survey of the existing Swedish national capability to detect an attempt to smuggle nuclear material or other radioactive substances. The capacity to perform a more thorough analysis of a seized sample has also been investigated. The study shows that Sweden today has a small capacity to disclose a smuggling attempt of such materials. The limited detection capacity that exists is not sensitive enough for this purpose, and is not used in an optimal way. Furthermore, relevant education of the custom officers is needed. Today, a national capability for an initial analysis of seized material exists, but action plans describing the handling of the material should be resolved. The high number of seizures of radioactive material in countries having a better detection capability indicates that illicit trafficking of radioactive materials is still a problem. In Sweden, we so far do not have many reported incidents of illicit trafficking - partly due to our limited capacity to detect radioactive material - however, we do not know how many incidents that really have occurred. Fixed installations for detection at the border controls are the most efficient way to improve our capacity for detecting nuclear material. An initial pilot study is suggested to be able to estimate the need. Increased education of the custom officers, establishment of formal routines for handling and analysis of seized materials, and to formalise the contacts with international analysis laboratories are also identified as important factors to be improved.

Drug problem in southeast and southwest Asia.

Kulsudjarit, Kongpetch

2004-10-01

In 2002, the drug problem in Southeast and Southwest Asia was serious, particularly in the production of opium and heroin in Afghanistan, Myanmar, and Laos, the three largest producers of illicit opium in the world. The increasing illicit manufacture of ATS, particularly methamphetamine, in Southeast Asia, mainly in China and Myanmar, was also a major concern. Some reports indicated that ephedrine, used for illicitly producing methamphetamine in Southeast Asia, is diverted and smuggled out of China and India, whereas caffeine, the adulterant used for producing methamphetamine tablets, is mainly smuggled into Myanmar through its border with Thailand. Seizure data showed a dramatic increase in trafficking in MDMA through Southeast Asia. In terms of the drug epidemic, in 2002, cannabis remained overall the main drug of abuse in all of the countries of Southeast and Southwest Asia. Opiates, mainly opium and heroin, were also the drugs of choice except in Thailand, where opiate abuse declined, but ATS was the main drug of abuse due to its low cost and availability. A significant increase in ATS abuse, amphetamine, methamphetamine, and MDMA among the youth who smoked, sniffed, and inhaled them was reported in Cambodia, China, Indonesia, Laos, Myanmar, the Philippines, and Thailand. Injecting drug use among opiate abusers has been identified as the prime cause of the rapid spread of HIV/AIDS in Southeast and Southwest Asia.

From cigarette smuggling to illicit tobacco trade.

Science.gov (United States)

Joossens, Luk; Raw, Martin

2012-03-01

Tax policy is considered the most effective strategy to reduce tobacco consumption and prevalence. Tax avoidance and tax evasion therefore undermine the effectiveness of tax policies and result in less revenue for governments, cheaper prices for smokers and increased tobacco use. Tobacco smuggling and illicit tobacco trade have probably always existed, since tobacco's introduction as a valuable product from the New World, but the nature of the trade has changed. This article clarifies definitions, reviews the key issues related to illicit trade, describes the different ways taxes are circumvented and looks at the size of the problem, its changing nature and its causes. The difficulties of data collection and research are discussed. Finally, we look at the policy options to combat illicit trade and the negotiations for a WHO Framework Convention on Tobacco Control (FCTC) protocol on illicit tobacco trade. Twenty years ago the main type of illicit trade was large-scale cigarette smuggling of well known cigarette brands. A change occurred as some major international tobacco companies in Europe and the Americas reviewed their export practices due to tax regulations, investigations and lawsuits by the authorities. Other types of illicit trade emerged such as illegal manufacturing, including counterfeiting and the emergence of new cigarette brands, produced in a rather open manner at well known locations, which are only or mainly intended for the illegal market of another country. The global scope and multifaceted nature of the illicit tobacco trade requires a coordinated international response, so a strong protocol to the FCTC is essential. The illicit tobacco trade is a global problem which needs a global solution.

Smuggling, non-fundamental uncertainty, and parallel market exchange rate volatility

OpenAIRE

Richard Clay Barnett

2003-01-01

We explore a model where smuggling and a parallel currency market arise, owing to government restrictions that prevent agents from legally holding foreign exchange. Despite such restrictions, agents are able to diversify their savings, holding both domestic and parallel foreign cash, basing their portfolio allocation on current and prospective parallel exchange rates. We attribute movements in parallel rates to non-fundamental uncertainty. The model generates equilibria with both positive and...

Objectives To examine the behaviour and attitudes related to smoking and contraband tobacco products among smokers in two socially deprived areas. Design Cross sectional study with qualitative semistructured interviews, augmented by smokers' day grid. Setting Two areas of socioeconomic deprivation in Edinburgh. Participants 50 male and 50 female smokers aged 25-40 years randomly selected from general practitioners' lists from two health centres, each located in an area of deprivation. Results Most smokers wanted to quit but felt unable to because of the importance of smoking in their daily routine and their addiction to nicotine. Strategies for maintaining consumption levels in the face of increasing cigarette prices and low income included purchasing contraband cigarettes and tobacco. Vendors were contacted through social networks, family, and friends as well as common knowledge of people and places, particularly pubs where contraband was available. Most users of contraband considered that smugglers were providing a valuable service. Purchasing contraband tobacco was viewed as rational in the face of material hardship. Many smokers criticised the government for its high tobacco taxation and the lack of local services to help them to stop smoking. Conclusions Smokers in deprived areas perceive a lack of support to help them to stop smoking. Cigarette and tobacco smuggling is therefore viewed positively by low income smokers as a way of dealing with the increasing cost of cigarettes. Smokers in areas of deprivation may thus show little support for tackling smuggling until more action is taken to deal with the material and personal factors that make it difficult for them to quit. What is already known on this topicAreas of deprivation have the highest rates of smoking and lowest levels of cessationAround 25-30% of cigarettes consumed in the United Kingdom are contrabandWe know little about the attitudes of smokers in these areas to smuggled cigarettes or whether and

An Analysis of Some Highly-Structured Networks of Human Smuggling and Trafficking from Albania and Bulgaria to Belgium

Full Text Available The authors examine the logistic ecology of 30 large-scale networks that were active in human smuggling and trafficking from Albania and Bulgaria to Belgium (1995–2003. Ten networks were studied in greater detail in order to determine three final profiles of networks, based on their use of structural and operational intermediary structures. They are called the “individual infiltration” and the “structural infiltration” human smuggling patterns, and the “violent-control prostitution” trafficking pattern. It should be noted that the business is organized in such a way that the organizers of the logistical support are never inculpated.

Full Text Available One method of drug smuggling is body packing or body stuffing, placement of narcotics (opium, heroin, hashish, … inside intestinal tract for transfer from city to city or country to country. Estimating of the methods for transferring, content of packets, packaging, cause of death and results of diagnostic and therapeutic methods can effectively decrease the number of body packer and law execution. This study is case series by randomized sampling. Several parameters such as sex, age, marital status, addiction, job, level of education, type of opioids and their weight and number of packets, result of abdominal X-ray, surgery needs, were collected from April 1999 to December 2000. Through this period of time, 32 male smuggler who had swallowed drug packets were detained. The average age was 41 years (max=62, min=20. The minimum weight of the opium carried by this smugglers was below 20 gram and maximum weight was 1000 grams (median=360 grams. The minimum number of packets were one packet and maximum number of packets were 54 (median=10 packets. In 84 percent of body smugglers the content of packets was opium, 13 percent was heroin and 3 percent was hashish. From the cases, 81 percent of smugglers were addicts themselves. Death occurred in 7 cases from which 3 were after surgery.

1998-01-01

One of the milestones of the WCO Enforcement Programme on Combating nuclear and other radioactive materials smuggling is to raise awareness among Customs services and reinforce their enforcement programmes by providing them training materials and training courses. The International Atomic Energy Agency (IAEA) is recognized as a unique international organization in nuclear field to assist the WCO Secretariat by providing technical input in developing awareness/training materials and conducting training courses. In line with their policies for the effective combating of nuclear and other radioactive materials smuggling, both international organizations have agreed to co-operate by regular attendance each other's technical meetings. This approach was formalized with the signing of Memorandum of Understanding on 13 May 1997. The WCO and IAEA training strategy has been to give priority to the Eastern and Central Europe region and the first joint training course was held in Vienna for Customs Trainers on 2-6 June 1997 and the second course is scheduled for Customs and Police officers of the same region in September 1998.

This article is the first in a series of international case studies developed by the American Cancer Society to illustrate use of publicly available surveillance data for regional tobacco control. A descriptive analysis of Brazil and Paraguay cigarette production and trade data from official sources. Per capita cigarette consumption for Brazil and its neighbour was calculated from 1970 to 1998 using data on production, imports, and exports from NATIONS, the National Tobacco Information Online System. A 63% decrease was observed in the estimate of per capita consumption of cigarettes in Brazil between 1986 and 1998 (from 1913 cigarettes per person in 1986 to 714 cigarettes per person in 1998) and a 16-fold increase in Paraguay was observed during the same period (from 678 cigarettes per person in 1986 to 10 929 cigarettes per person in 1998). Following Brazil's 1999 passage of a 150% cigarette export tax, cigarette exports fell 89% and Brazil's estimated per capita consumption rose to 1990 levels (based on preliminary data). Per capita consumption in Paraguay also fell to 1990 levels. These trends coincide with local evidence that large volumes of cigarettes manufactured in Brazil for export to Paraguay are smuggled back and consumed as tax-free contraband in Brazil. It is hoped that this case study will draw wider public attention to the problems that smuggling presents for tobacco control, help identify other countries confronting similar issues, and stimulate effective interventions.

A.Q. Khan Nuclear Smuggling Network

Molly MacCalman

2016-03-01

Full Text Available Abdul Qadeer Khan, widely viewed as the father of Pakistan’s nuclear weapons program, was arrested on January 31, 2004 for his key role in the black market sale of nuclear technology and equipment to Iran, North Korea, Libya, and possibly others. A.Q. Khan’s nuclear smuggling network prospered throughout the 1980s and 1990s and was linked to middlemen and businesses in over 20 countries. The network offered buyers a menu of both technical expertise and materials with prices ranging from millions to hundreds of millions of dollars. The Khan network was ultimately exposed largely due to years of intelligence gathering by the United States and the United Kingdom. However, very few of the network’s members have been successfully prosecuted and the demand for nuclear material by both state and non-state actors continues. The exposure of Khan’s network confirmed that a non-state actor could procure and sell a turnkey nuclear weapons program to willing buyers.

Fifty-year old man was found dead in the bathroom of his apartment. Forensic autopsy was ordered to determine the cause and manner of death. Autopsy revealed the presence of 55 latex "balls" in the stomach and foregut. In the past the victim was suspected of drug's dealing and smuggling. The content of "balls" and biological material (blood, urine, bloody fluid from internal organs) were analysed with LC MS/MS in the Chair and Department of Forensic Medicine and Forensic Toxicology, Medical University of Silesia in Katowice. The range of cocaine' concentration in the "balls" was 91.2-96.1%, whereas concentration in blood - 107.50 microg/ml, in urine - 284.60 microg/ml and in bloody fluid - 192.30 microg/ml. The cause of death was acute cocaine intoxication.

The long postwar and the politics of penicillin: early circulation and smuggling in Spain, 1944-1954.

2014-01-01

In this paper I explore the early circulation of penicillin. I review the early distribution in Spain of a scarce product, reflect on the available sources about the illegal penicillin trade and discuss some cases of smuggling. I argue the early distribution of penicillin involved time and geography, a particular chronology of post Second World War geopolitics. Penicillin practices and experiences belong to this period, in a dictatorship that tolerated smuggling and illegal trade of other products, some, like penicillin, produced in neighbouring countries. As a commodity that crossed borders, penicillin, transiting between the law and hidden trade, between countries and social domains--between war fronts and from a war front to an urban site to be sold--reveals practices of the early years of prosperity in the 1950s. These transits were permanent tests of a society based on taxes and exchanges, law and bureaucracy, control, discipline and the creation of standards.

Smuggling as the "key to a combined market": British American Tobacco in Lebanon.

Science.gov (United States)

Nakkash, R; Lee, K

2008-10-01

To understand the strategy of British American Tobacco (BAT) and other transnational tobacco companies (TTCs) to gain access to the Lebanese market, which has remained relatively closed under monopoly ownership and political instability. Analysis of internal industry documents, local language secondary sources and industry publications. TTCs have relied on legal and illegal channels to supply the Lebanese market since at least the 1970s. Available documents suggest smuggling has been an important component of BAT's market entry strategy, transported in substantial quantities via middlemen for sale in Lebanon and neighbouring countries. TTCs took advantage of weak and unstable governance, resulting in uncertainty over the Regie's legal status, and continued to supply the contraband trade despite appeals by the government to cease undermining its revenues. Since the end of the civil war in the early 1990s, continued uncertainty about the tobacco monopoly amid political instability has encouraged TTCs to seek a legal presence in the country, while continuing to achieve substantial sales through contraband. Evidence of the complicity of TTCs in cigarette smuggling extends to Lebanon and the Middle East where this trade has especially benefited from weak governance and chronic political instability. The regional nature of TTC strategy supports strong international cooperation under the Framework Convention on Tobacco Control to tackle the problem.

Detection of smuggling of nuclear material covered by a legal transport of radioactive material

Full text: One of the worst scenarios for detection of illicit trafficking of nuclear material is when a legal transport of radioactive material is used to cover the radiation of the smuggled uranium. Feasibility study was performed in the Institute of Isotopes and Surface Chemistry of the Chemical Research Centre of the Hungarian Academy of Sciences (hereinafter: Institute) in order to study the possible on site measurement techniques and approaches applicable in such cases. As the type A and type B packages always incorporate a feature such as a seal, in a realistic scenario the confiscated nuclear material is expected to be placed outside the package. The passive neutron emission of the uranium is negligible for a reasonable isotopic abundance therefore the feasibility study was concentrating on non-destructive, passive gamma- spectrometric methods. Possible application of Nal (diameter 40x40 mm 3 , large planar (15x15x3 mm 3 ) and a hemispheric CdZnTe (500 mm 3 , and high purity Germanium detectors was investigated. During the on site measurements portable electronics, mini multichannel analyzer, palmtop and/or notebook computer were used. The shielding material of the packages was lead or depleted uranium. The smuggled material was simulated by a package of reactor fuel pellets containing low enriched or natural uranium (materials confiscated in earlier cases) and standards containing low enriched uranium. During the supposed scenario the portal monitor provides an indication of an elevated level of the environmental radioactivity. Then the responsible (e.g. customs) officer investigate the vehicle by a hand-held survey meter in order to search for peaks in dose rates. If a peak was localized, which is different from the position of the legally transported package(s) the officer requests for the expertise of the designated institutes. The following model cases provided the basic conclusion: 1. The legal transport of the radioactive material was simulated by a

Background Drugs play an increasing role in contemporary prison life. Prisoners’ drug use, drug smuggling and drug selling have also had a growing impact on the work routines and practices of prison officers. This has led to critiques that prison staff have become ‘too lenient’ regarding drug use....... Methods Based on observational data, qualitative interviews and survey data, this study examines the role of drugs in the way Danish prison officers exercise power. Results Two forms of power are analysed: institutional power, by which the officers can sanction or reward inmates in everyday prison life......, and personal power, by which the officers’ personal authority and skills can reduce the more intrusive aspects of prison control. These forms of power are applied by officers’ use of discretion in order to maintain what they consider to be adequate levels of peace and order in the prison wings. It is shown...

Beyond the drug-terror nexus: drug trafficking and state-crime relations in Central Asia.

Science.gov (United States)

De Danieli, Filippo

2014-11-01

In the wake of collapse of the Soviet Union, Central Asia has transformed into a key hub along the Afghan opiates trafficking routes. Around 30 percent of the heroin manufactured in Afghanistan is estimated to be smuggled through Central Asian republics in its way to booming drug markets in Russia and Eastern Europe. Building upon available evidence and extensive fieldwork research, the article seeks to confute mainstream analyses which emphasize connections between criminal and terrorist networks. The focus is on conducive factors for the establishment of drug routes in Central Asia, the characteristics of drug related networks, and the nature of political-criminal relations across the region. It is argued that in all five Central Asia republics strategic partnerships have formed between drug traffickers and state actors around the exploitation of drug rents and that mafias' influence on politics is stronger in Tajikistan and Kyrgyzstan, the region's poorest countries. By moving the focus from narco-terror to the state-crime connections, the article provides a critical insight into political economy issues surrounding a complex and multifaceted phenomenon such as the drug trade.

Recent trends suggest that cocaine smugglers have become more and more inventive to avoid seizures of large amounts of cocaine transported between countries. We report a case of a mail parcel containing a dance pad which was seized at the Customs Department of Brussels Airport, Belgium. After investigation, the inside of the dance pad was found to contain a thick polymer, which tested positive for cocaine. Analysis was performed using a routine colorimetric swipe test, gas chromatography coupled with mass spectrometry and nuclear magnetic resonance spectroscopy. The polymer was identified as polyvinyl alcohol (PVA) and contained 18% cocaine, corresponding to a street value of € 20,000. Laboratory experiments showed that cocaine could be easily extracted from the PVA matrix. This case report reveals a new smuggling technique for the transportation of large amounts of cocaine from one country to another. © 2011 American Academy of Forensic Sciences.

To examine the behaviour and attitudes related to smoking and contraband tobacco products among smokers in two socially deprived areas. Cross sectional study with qualitative semistructured interviews, augmented by smokers' day grid. Two areas of socioeconomic deprivation in Edinburgh. 50 male and 50 female smokers aged 25-40 years randomly selected from general practitioners' lists from two health centres, each located in an area of deprivation. Most smokers wanted to quit but felt unable to because of the importance of smoking in their daily routine and their addiction to nicotine. Strategies for maintaining consumption levels in the face of increasing cigarette prices and low income included purchasing contraband cigarettes and tobacco. Vendors were contacted through social networks, family, and friends as well as common knowledge of people and places, particularly pubs where contraband was available. Most users of contraband considered that smugglers were providing a valuable service. Purchasing contraband tobacco was viewed as rational in the face of material hardship. Many smokers criticised the government for its high tobacco taxation and the lack of local services to help them to stop smoking. Smokers in deprived areas perceive a lack of support to help them to stop smoking. Cigarette and tobacco smuggling is therefore viewed positively by low income smokers as a way of dealing with the increasing cost of cigarettes. Smokers in areas of deprivation may thus show little support for tackling smuggling until more action is taken to deal with the material and personal factors that make it difficult for them to quit.

Full Text Available The author of the paper provides an overview and analysis of Croatian criminal legislation with regard to criminal activities of human smuggling and trafficking. She points out to the similarities and differences between the criminal acts of illegal transfer of persons across the state border or illegal entering, movement and residence in the Republic of Croatia, other EU Member States or signatories of the Schengen Agreement and human trafficking, comparing and analyzing the legal norms of the old and the new Criminal Code of the Republic of Croatia, international instruments and jurisprudence. Emphasized is the importance of early recognition of the criminal act, especially for the victims. Attention is drawn to the disparity of case law on matters of personal gain as an essential element of this criminal activity, but also to the absence of clearly defining the act of attempting illegal entering, movement and residence in the Republic of Croatia, other EU Member States or signatories of the Schengen Agreement. This paper investigates and analyzes the current situation regarding illegal crossing of state borders of the Republic of Croatia on the basis of available statistical data. Conducted was the analysis of the situation de lege lata in case law in relation to persons registered, accused and convicted of human smuggling and, also, especially for human trafficking. In conclusion, given are the proposals and measures de lege ferenda that need to be implemented in order to combat human smuggling and trafficking, and to successfully fight this type of organized crime.

Full Text Available La industria tabacalera multinacional, siempre en busca de nuevos mercados, ha realizado una agresiva expansión hacia naciones de ingreso medio y bajo. Al mismo tiempo se ha producido un marcado incremento en el contrabando de tabaco, especialmente de cigarrillos. Ese contrabando provoca graves pérdidas fiscales a los gobiernos de todo el mundo, erosiona las políticas de control del tabaco e incentiva a la delincuencia organizada internacional. Por otro lado, el contrabando provoca incrementos en el consumo y la demanda de tabaco, los cuales benefician a las tabacaleras. Más aún, existe evidencia de que la industria tabacalera internacional ha propiciado el contrabando de cigarrillos e incluso ha participado directamente en el mismo. Al mismo tiempo, realiza costosas campañas de cabildeo entre los gobiernos para combatir los impuestos y favorecer sus intereses. Los estudios académicos y la evidencia empírica demuestran que es posible avanzar en el control del tabaquismo mediante el incremento de las tasas fiscales sin provocar incrementos significativos en el contrabando. Para ello es necesario combatir este delito mediante acciones y controles multilaterales como los que fueron establecidos en el Convenio Marco para el Control del Tabaco (CMCT, el cual presenta las bases para enfrentar el contrabando mediante un enfoque internacional y global. También es necesario aumentar radicalmente las penas judiciales al contrabando y hacer responsable a la industria tabacalera, incluyendo fabricantes y distribuidores, por el destino final de sus exportaciones.The international tobacco industry, in its constant quest for new markets, has expanded aggressively to middle- and low-income nations.

Lindström, Martin

2005-12-01

To study the impact of social participation, trust and the miniaturisation of community, i.e. high social participation/low trust, on consumption of homemade liquor and smuggled liquor during the past year. The Scania 2000 public health survey is a cross-sectional, postal questionnaire study. A total of 13,604 persons aged 18-80 years were included. A logistic regression model was used to investigate the association between the social capital variables and illegal alcohol consumption. The multivariate analyses analysed the importance of confounders (age, country of origin, education and economic stress) on the differences in consumption of homemade and smuggled liquor according to the social capital variables. A 28.2% proportion of all men and 14.9% of all women had consumed homemade liquor during the past year. The proportions who had consumed smuggled liquor during the past year were even higher, 40.1% among men and 21.4% among women. Both forms of illegal alcohol consumption were significantly positively associated with social participation and negatively associated with trust. The miniaturisation of community category, i.e. high social participation/low trust, had significantly higher risks of consumption during the past year of the consumption of both forms of illegally provided alcohol compared to the high social capital (high social participation/high trust) category, while the low social participation/high trust category had significantly lower risks. High social participation combined with low trust is positively associated with consumption of illegally provided alcohol. The results have implications for alcohol prevention programs, because structural/social factors that may hinder information and norms concerning illegal alcohol have been identified in this study.

Smuggling Drugs into the Brain: An Overview of Ligands Targeting Transcytosis for Drug Delivery across the Blood-Brain Barrier.

The blood-brain barrier acts as a physical barrier that prevents free entry of blood-derived substances, including those intended for therapeutic applications. The development of molecular Trojan horses is a promising drug targeting technology that allows for non-invasive delivery of therapeutics into the brain. This concept relies on the application of natural or genetically engineered proteins or small peptides, capable of specifically ferrying a drug-payload that is either directly coupled or encapsulated in an appropriate nanocarrier, across the blood-brain barrier via receptor-mediated transcytosis. Specifically, in this process the nanocarrier-drug system ("Trojan horse complex") is transported transcellularly across the brain endothelium, from the blood to the brain interface, essentially trailed by a native receptor. Naturally, only certain properties would favor a receptor to serve as a transporter for nanocarriers, coated with appropriate ligands. Here we briefly discuss brain microvascular endothelial receptors that have been explored until now, highlighting molecular features that govern the efficiency of nanocarrier-mediated drug delivery into the brain.

Preventive effort was tighten the security and pacification in prison’s gate, sweeping in convict’s room, check every goods accurately which is entered into prison, and etc. However, the repressive effort was reported the smuggling or the convict who involved to the Police officer to get further law process.

Quantitative and qualitative estimates of cross-border tobacco shopping and tobacco smuggling in France.

In France, cigarette sales have fallen sharply, especially in border areas, since the price increases of 2003 and 2004. It was proposed that these falls were not due to people quitting smoking but rather to increased cross-border sales of tobacco and/or smuggling. This paper aims to test this proposition. Three approaches have been used. First, cigarette sales data from French sources for the period 1999-2006 were collected, and a simulation of the changes seen within these sales was carried out in order to estimate what the sales situation would have looked like without the presence of foreign tobacco. Second, the statements regarding tobacco consumed reported by the French population with registered tobacco sales were compared. Finally, in order to identify the countries of origin of foreign tobacco entering France, we collected a random sample of cigarette packs from a waste collection centre. According to the first method, cross-border shopping and smuggling of tobacco accounted for 8635 tones of tobacco in 2004, 9934 in 2005, and 9930 in 2006, ie, between 14% and 17% of total sales. The second method gave larger results: the difference between registered cigarette sales and cigarettes declared as being smoked was around 12,000 to 13,000 tones in 2005, equivalent to 20% of legal sales. The collection of cigarette packs at a waste collection centre showed that foreign cigarettes accounted for 18.6% of our sample in 2005 and 15.5% in 2006. France seems mainly to be a victim of cross-border purchasing of tobacco products, with the contraband market for tobacco remaining modest. in order to avoid cross-border purchases, an increased harmonization of national policies on the taxation of tobacco products needs to be envisaged by the European Union.

Toth, Alexander G; Mitchell, Ojmarrh

2018-05-01

The purpose of this study is to utilize unique qualitative data to determine the effects of sporadic international drug interdictions on drug trafficking, and to assess whether the responses of drug traffickers align with rational choice theory. Qualitative data obtained from 23 high-level United States Drug Enforcement Administration (DEA) informants, who are embedded in international drug trafficking groups, are examined to identify common responses to drug interdiction operations. The findings indicate that sporadic counter-drug interdictions do not a have permanent deterrent effect on transnational drug smuggling operations. However, these types of law enforcement operations produce temporary alterations in drug trafficking, as traffickers adopted a variety of methods to thwart the efforts of law enforcement-often by relying on information acquired from corrupt local law enforcement. The results also indicate that while interdiction operations displaced trafficking activities (temporally, spatially, and methodological), there is little evidence that drug traffickers responded to such operations by moving into new areas (i.e., malign spatial displacement). Sporadic international drug interdiction programs do little to deter drug trafficking organizations (DTOs) from engaging in their illicit trade. Instead, DTOs adjust in a calculating manner to these operations to ensure that their illegal products reach consumer marketplaces, which is congruent with the rational choice theoretical perspective.

Full Text Available A 42-year-old African male was brought by the police to the emergency department under suspicion of drug smuggling by body-packing. Plain abdominal radiograph showed multiple foreign bodies within the gastrointestinal tract. Contrast-enhanced abdominal CT confirmed the findings, and the patient admitted to have swallowed “balls” of hashish. Body-packing is a recognized method of smuggling drugs across international borders. Body packers may present to the emergency department because of drug toxicity, intestinal obstruction, or more commonly, requested by law-enforcement officers for medical confirmation or exclusion of suspected body packing.

Saeger, Kevin J [Los Alamos National Laboratory; Cuellar, Leticia [Los Alamos National Laboratory

2010-01-01

Nuclear weapons proliferation is an existing and growing worldwide problem. To help with devising strategies and supporting decisions to interdict the transport of nuclear material, we developed the Pathway Analysis, Threat Response and Interdiction Options Tool (PATRIOT) that provides an analytical approach for evaluating the probability that an adversary smuggling radioactive or special nuclear material will be detected during transit. We incorporate a global, multi-modal transportation network, explicit representation of designed and serendipitous detection opportunities, and multiple threat devices, material types, and shielding levels. This paper presents the general structure of PATRIOT, and focuses on the theoretical framework used to model the reliabilities of all network components that are used to predict the most likely pathways to the target.

Locating sensors for detecting source-to-target patterns of special nuclear material smuggling: a spatial information theoretic approach.

In this paper, a spatial information-theoretic model is proposed to locate sensors for detecting source-to-target patterns of special nuclear material (SNM) smuggling. In order to ship the nuclear materials from a source location with SNM production to a target city, the smugglers must employ global and domestic logistics systems. This paper focuses on locating a limited set of fixed and mobile radiation sensors in a transportation network, with the intent to maximize the expected information gain and minimize the estimation error for the subsequent nuclear material detection stage. A Kalman filtering-based framework is adapted to assist the decision-maker in quantifying the network-wide information gain and SNM flow estimation accuracy.

The nuclear smuggling international technical working group: Making a difference in combating illicit trafficking

International Nuclear Information System (INIS)

Niemeyer, S.; Koch, L.

2001-01-01

The ITWG was first formed in 1995 for the purpose of fostering international cooperation for combating illicit trafficking of nuclear materials. The initial focus for the ITWG was on the development of nuclear forensics to help answer attribution questions regarding nuclear materials of unknown origin. More recently, the ITWG has also expanded its focus to include detection of nuclear materials during transit. This paper presents some of the key developments by this group and their potential impact for combating nuclear smuggling. The initial focus of the ITWG was to write a status report on international cooperation on nuclear smuggling forensic analysis. This report was submitted to the G-8 countries, and shortly thereafter, nuclear forensics was endorsed at the Moscow Summit in April, 1996, as part of an illicit trafficking program. The ITWG's primary goal is to develop a preferred approach to nuclear forensic investigations that is widely understood and accepted as credible. The technical elements include: 1) development of protocols for a) collection and preservation of evidence and b) for laboratory investigation; 2) prioritizing of techniques for forensic analysis; 3) development of forensic databanks to assist in interpretation; 4) executing inter-laboratory exercises; and 5) facilitating technical assistance to countries upon request. The development of protocols has been conducted jointly by law enforcement officials and laboratory scientists. A major focus during much of the past five years has been the development of a model action plan for nuclear forensics of seized nuclear materials. This action plan lays out the elements that are needed in the instance that illicit nuclear material is uncovered, e.g. incident response, crime scene analysis, collection of evidence (both radioactive and 'traditional' forensics, transportation to a nuclear facility, subsequent laboratory analysis, and then development of the case. At the most recent meeting (ITWG-6

Assessing Detecting and Deterring the Threat of Maritime Nuclear and Radiological Smuggling in the Western Indian Ocean Region

Energy Technology Data Exchange (ETDEWEB)

Khan, M. Umer [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States). Cooperative Monitoring Center

2017-03-01

This paper proposes that current maritime smuggling routes in the western Indian Ocean region are similar to those in the past and that the motivations of terrorist groups and the presence of radioactive sources in the Indian Ocean littoral and other states present a significant security threat. The majority of regional terrorist groups have a hybrid structure, piggybacking on criminal activity to fund their terror activities. Additionally, states have used maritime routes in the Indian Ocean region to transport nuclear materials and missiles. Thus, the maritime dimension of such threats remains, and may be increasing. This paper focuses on issues, motivations, pathways, and methods to detect and interdict nuclear and radiological trafficking. It analyzes the potential use of maritime technology applications for radiation detection and presents recommendations for states and multinational nonproliferation advocacy organizations to address the threat in the Indian Ocean region.

Body packing, pushing, and stuffing are hazardous practices with complex medicolegal and social implications. A radiologist plays both a social and a medicolegal role in their assessment, and it should not be limited only to the identification of the packages but must also provide accurate information about their number and their exact location so as to prevent any package remains in the body packer. Radiologists must also be able to recognize the complications associated with these risky practices. Imaging assessment of body packing is performed essentially through plain abdominal X-ray and computed tomography scans. Ultrasound and magnetic resonance imaging, although with some advantages, actually have a limited use. Copyright © 2014 Elsevier Inc. All rights reserved.

The main task of the General Directorate of Customs Enforcement is to prevent, prosecute and investigate any act of smuggling not only in customs areas (border crossing) but also all over Turkey as well as to be responsible for carrying out the task of the customs procedure partially in customs area. General Directorate of Customs Enforcement implements the task with regard to the prevention, prosecution and investigation of violation of customs legislation, i.e. combating all kinds of smuggling and illegal activities. As far as organizational structure of GDCE is concerned, it has Center and District units. In the Center, under the General Director, three Deputy General Directors exist. There are five Heads of Departments linked to the concerned Deputy General Director. One of them is related with anti-smuggling and anti-narcotics activities as Head of Department of Investigation Intelligence and Prosecution of Anti-Smuggling and Anti-Narcotics. Four Directorates have fulfilled their activities in this Department. The role of Directorate of Anti-Smuggling is to coordinate districts units activities related with combating commercial fraud. That of anti-narcotics is responsible for directing and monitoring of the activities on fighting drugs smuggling done by regional units. The directorate of criminal laboratory is in the stage of being set up. The aim of this directorate is to determine whether or not any suspected material is drugs, and whether any suspected document used in customs procedure is genuine of false. The Directorate of Data Processing and Assessment has: performed the data processing affairs; collected information on seizure case, suspected persons and vehicles; analyzed and distributed information and intelligence. At the regional level, GDCE has 18 district headquarters. There are also many units linked to Regional Headquarters. Especially, after the fall of the Soviet

Miltefosine (hexadecylphosphocholine, HePC), the first orally active drug successful against leishmaniasis, is especially active on the visceral form of the disease. Resistance mechanisms are almost exclusively associated to dysfunction in HePC uptake systems. In order to evade the requirements of its cognate receptor/translocator, HePC-resistant Leishmania donovani parasites (R40 strain) were challenged with constructs consisting of an ω-thiol-functionalized HePC analogue conjugated to the cell-penetrating peptide (CPP) Tat(48-60), either through a disulfide or a thioether bond. The conjugates enter and kill both promastigote and intracellular amastigote forms of the R40 strain. Intracellular release of HePC by reduction of the disulfide-based conjugate was confirmed by means of double tagging at both the CPP (Quasar 670) and HePC (BODIPY) moieties. Scission of the conjugate, however, is not mandatory, as the metabolically more stable thioether conjugate retained substantial activity. The disulfide conjugate is highly active on the bloodstream form of Trypanosoma b. brucei, naturally resistant to HePC. Our results provide proof-of-mechanism for the use of CPP conjugates to avert drug resistance by faulty drug accumulation in parasites, as well as the possibility to extend chemotherapy into other parasites intrinsically devoid of membrane translocation systems.

The role of customs services and World Customs Organization (WCO)'s enforcement programme to combat nuclear and other radioactive materials smuggling

International Nuclear Information System (INIS)

Saka, E.

1999-01-01

The World Customs Organization (established as the Customs Co-operation Council in 1952) is an independent inter-governmental body with world-wide membership (150) whose enforcement mission could be summarized as 'to assist its Members in strengthening their enforcement measures through training and technical programmes designed to combat Customs offences', which also include nuclear and other radioactive materials smuggling. One of the best strategies for an effective fight against illicit trafficking in nuclear and other radioactive materials is to stop their illegal movement at the national border before entering or leaving the country. From this point, Customs services are unique governmental cross-border control agencies, which are mostly located at national cross-border checking points. In addition to this local advantage, Customs expertise and authority in checking documents, goods, vehicles and passengers deserve special mentioning. It should also be noted that Customs services have great experience on how to combat and respond to transnational crime and criminals. On the other hand, in order to maximize on their experience, they should be furnished with sufficient authority for investigation, detection equipment and supported through relevant training programmes. In line with the request made by Member States, the World Customs Organization (WCO) Secretariat has recently developed an enforcement programme on combating nuclear and other radioactive materials smuggling. This programme is based on awareness raising, development of training materials, designing training programmes, promoting exchange of information and improving co-operation at all levels. The WCO Database, the WCO Regional Intelligence Liaison (RILO) project and WCO bilateral and multilateral co-operative initiatives are three key tools which enable Customs administrations to develop accurate, timely and rapid exchange of information and intelligence.

Adams, M; Effertz, T

2011-10-01

The consumption of tobacco products is one of the main causes of illnesses. An often neglected but highly effective instrument for fiscal and preventive purposes is higher taxes on tobacco products. The tobacco industry however claims that higher taxes have tremendous effects on smuggling activity with additional costs with regard to law enforcement. The claim appears to be substantiated by a study which collects and documents the amounts of discarded empty cigarette packs, and which is used to estimate the fraction of illegally imported cigarettes. We show that this study makes use of systematic misspecifications and impreciseness and thus seems to pursue the aim of showing an exaggerated high amount of illegally imported cigarettes. The industry's claim that two thirds of non-taxed cigarettes in Germany are imported illegally, thus lacks any sound, well-grounded empirical corroboration. © Georg Thieme Verlag KG Stuttgart · New York.

This report summarizes the efforts completed in identifying candidate fluorescence compounds and radioisotopes for a developing tagging system. The tagging system is being developed as a deterrent to nuclear smuggling, by providing a means of: (1) tracing materials and pilferers to the facility of origin for any recovered special nuclear materials; (2) inventory control of long-term stored items containing special nuclear materials; and (3) tracking materials transferred between facilities. The tagging system uses four types of tagging materials to cover a range of applications intended to prevent the pilfering of special nuclear materials. One material, fluorescent compounds which are invisible without ultraviolet or near-infrared detection systems, is marked on controlled items with a tracking pattern that corresponds to a specified item in a specified location in the data control system. The tagging system uses an invisible, fluorescent dusting powder to mark equipment and personnel who inappropriately handle the tagged material. The tagging system also uses unique combinations of radionuclides to identify the facility of origin for any special nuclear material. Currently, 18 long-lived radioisotopes, 38 short-live radioisotopes and 10 fluorescent compounds have been selected as candidate materials for the tagging system

Determination of Smuggled Cigarette Characteristics in Brazil and Their Potential Risk to the Human Health

Directory of Open Access Journals (Sweden)

Cleber Pinto da Silva

2016-07-01

Full Text Available The objective of this study was to determine the different characteristics of tobacco found in thirty brands of smuggled cigarettes in Brazil. Determination of arsenic through atomic absorption spectrometry in graphite oven was carried out and classical methodologies were employed to determine dirtiness, total ash, insoluble ash, humidity, tobacco pH and sidestream smoke pH. The methodology used to quantify arsenic presented quantification limit of 15.0 ng g-1 and detection limit of 4.0 ng g-1 in dry tobacco mass. The recovery of arsenic for the method purpose was 98.2% and relative standard deviation 6.0%. About 56% of the brands were observed to have arsenic concentrations above 20.0 ng g-1, which means nearly twice as much as the arsenic found in cigarettes sold legally in Brazil. Levels above the recommended value for humidity were found in 53% of brands. About 96% of the brands presented total ash content above that indicated by the Brazilian Pharmacopoeia. About 53% of the samples contained levels of insoluble ash above the limit. In 90% of the samples, the smoke was alkaline. In dirtiness tests, 81.2% of the brands presented some kind of contaminant, such as fungi, insect fragments, grass or mites. The characteristics revealed that the consumption of this kind of cigarette can increase risks to consumer health. DOI: http://dx.doi.org/10.17807/orbital.v8i3.832 

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.

Technologies for detection of nuclear materials

International Nuclear Information System (INIS)

DeVolpi, A.

1996-01-01

Detection of smuggled nuclear materials at transit points requires monitoring unknown samples in large closed packages. This review contends that high-confidence nuclear-material detection requires induced fission as the primary mechanism, with passive radiation screening in a complementary role. With the right equipment, even small quantities of nuclear materials are detectable with a high probability at transit points. The equipment could also be linked synergistically with detectors of other contrabond. For screening postal mail and packages, passive monitors are probably more cost-effective. When a suspicious item is detected, a single active probe could then be used. Until active systems become mass produced, this two-stage screening/interrogation role for active/passive equipment is more economic for cargo at border crossings. For widespread monitoring of nuclear smuggling, it will probably be necessary to develop a system for simultaneously detecting most categories of contraband, including explosives and illicit drugs. With control of nuclear materials at known storage sites being the first line of defense, detection capabilities at international borders could establish a viable second line of defense against smuggling

Print media is one of the key factors for defining public opinion and setting public policies regarding drugs. Therefore, surveying its content should provide us with a better understanding of the situation. The few existing surveys on this issue in Brazil point out discrepancies between print media and public health. The objective of the present survey is to enhance the analysis of drug-related stories in the Brazilian print media, based on a new time frame, in the year 2000. Major newspapers and magazines of all Brazilian state capitals have been surveyed throughout year 2000, with 4,669 stories presenting drugs as their main topic. A random sample of 964 stories underwent content analysis. Approximately half the stories (49.6%) dealt with smuggling- and repression-related issues. The remainder of the stories (50.4%) approached health, legislation, and public policy issues. Tobacco was the most widely discussed drug, with stories focusing mainly on damage caused by use and on measures for reducing consumption rates among the population. Articles about cocaine, also featured frequently in the print media, dealt mainly with the issues of drug dealing and of damage caused by cocaine use. Regarding marijuana, in addition to the law enforcement repressive approach, some articles dealt with decriminalization and therapeutic use. Articles about alcoholic beverages, featured less frequently in the print media, approached the subject matter from various angles. The number of stories on solvents and psychotropic medication was negligible. The results confirm discrepancies between print media coverage and epidemiology. They also indicate that each drug is approached differently, allowing for a better understanding of the "social climate" in Brazil regarding each drug. Of all possible social interventions for dealing with the issue repression stands out, whereas stories about treatment and damage reduction are relatively scarce. These findings suggest the need for improved

Forensic analysis of a smuggled HEU sample interdicted in Bulgaria

Niemeyer, S.; Hutcheon, I.

2002-01-01

Full text: A sample of HEU was seized in Rousse, Bulgaria on May 29, 1999, at a border crossing between Bulgaria and Romania. A search of the suspect's vehicle uncovered a lead canister hidden in the car trunk. The initial examination of the contents by Bulgarian scientists indicated that the sample was indeed HEU, and subsequently arrangements were made for a U.S. team of nuclear forensics scientists from several national laboratories to conduct a thorough examination. This report gives a summary of the results. The HEU sample was contained in a glass ampoule that was embedded in a yellow wax, and in turn the wax filled the inside of the cylindrical lead container. A broad set of techniques was used to examine both nuclear and non-nuclear materials. Our general experimental approach has been previously described at meetings of the Nuclear Smuggling International Technical Working Group (ITWG), but this case represents the application of the most diverse set of nuclear forensic measurements for an actual seized sample. Analysis of the HEU itself included particle characterization, stoichiometry, impurity elements, residual nuclides, age-dating, and U and Pu isotopics. Measurements by XRD, SEM, and TEM show that sample is mostly U3O8, with minor amounts of two other phases. The powder is extremely fine-grained (160 nm mean) and quite uniform in size. Most grains (95%) are equidimensional, with the remainder rod-or plate-shaped. The U is 72.7% U-235 with a high U-236 abundance of 12.1%. The sample is reprocessed, reactor-irradiated material. The original U enrichment was 90% and the irradiation burned up about 50% of the initial U-235. Pu is present at a very low-level (3 ppb); the Pu-239 abundance is 82% with 240/239=0.12. Three fission products were detected at low levels, giving unambiguous evidence of fuel recycling. The total impurity content is about 600 ppmw (mostly S, Cl, Fe, and Br), which we interpret as indicating a batch processing operation because the

The National Nuclear Security Administration’s Office of Nuclear Smuggling Detection and Deterrence (NSDD) has facilitated the installation of more than 3,500 radiation portal monitors (RPMs) at 606 sites in 56 countries worldwide. This collection of RPMs represents the world’s largest network of radiation detectors and provides one element in the defense-in-depth approach that supports the Global Nuclear Detection Architecture. These systems support NSDD’s mission to build partner country capability to deter, detect, and interdict the illicit transport of radiological and fissile material through strategic points of entry and exit at seaports, airports, and border crossings. NSDD works collaboratively with partner countries and international organizations to optimize the operation of these RPMs. The large amount of data provided by NSDD partner countries highlights the close cooperation and partnerships NSDD has built with 56 countries around the world. Thirty-seven of these countries shared at least some RPM-related data with NSDD in fiscal year 2016. This significant level of data sharing is a key element that distinguishes the NSDD office as unique among nuclear nonproliferation programs and initiatives: NSDD can provide specific, objective, data-driven decisions and support for sustaining the radiation detection systems it helped deploy. This data analysis report summarizes and aggregates the RPM data provided to the NSDD office for analysis and review in fiscal year 2016. The data can be used to describe RPM performance and characterize the wide diversity of NSDD deployment sites. For example, NSDD deploys detector systems across sites with natural background radiation levels that can vary by a factor of approximately six from site to site. Some lanes have few occupancies, whereas others have approximately 8,000 occupancies per day and the different types of cargo that travel through a site can result in site-wide alarm rates that range from near 0% at

U.S. second line of defense: preventing nuclear smuggling across Russia's borders

International Nuclear Information System (INIS)

Ball, D. Y.

1998-01-01

Preventing the theft of weapons-usable highly enriched uranium and plutonium in Russia is one of the central security concerns facing the US today. The dissolution of the highly centralized USSR and the resulting societal crisis has endangered Russia's ability to protect its more than 200 metric tons of plutonium and 1000 tons of highly enriched uranium (roughly 8 kg Pu or 25 kg HEU is sufficient to make a bomb). Producing this fissile material is the most difficult and expensive part of nuclear weapons production and the US must make every effort to ensure that fissile material (and nuclear-related technologies) does not reach the hands of terrorist groups, rogue states or other potential proliferators. In response to this concern, the US has undertaken a number of initiatives in partnership with Russia and other FSU states to prevent the theft of fissile material. The Material Protection, Control and Accounting Program (MPC and A) was begun in 1993 to prevent the theft of nuclear materials from Russian civilian complexes, that is facilities not under control of the Ministry of Defense, which is largely responsible for possession and oversight of nuclear weapons. The MPC and A program is considered the first line of defense against theft of nuclear material because its goal is to prevent theft of material at production and storage facilities. This year the Department of Energy (DOE) initiated a new program called the Second Line of Defense (SLD), the goal of which is to assist Russia in preventing the smuggling of nuclear material and weapons at its borders, either by land, sea or air. The SLD program represents an important phase in the overall effort to ensure the security of nuclear material and weapons in Russia. However, as the US engages Russian customs officials in this important project, Americans should keep in mind that providing equipment--even indigenous equipment--is insufficient by itself; material aid must be accompanied by rigorous inspection and

Kyrgyzstan - a virtual narco-state?

Science.gov (United States)

Kupatadze, Alexander

2014-11-01

Numerous myths have surrounded the drug trade in Central Asia over the past two decades. Analysts writing on the issue and the law enforcement structures of the respective countries often have no complete and accurate information about the scale of the trade, the different groups involved and the role of drugs-related money in politics. Generally there are two dominating views: the first considers Kyrgyzstan to be a virtual narco-state and overstates the involvement of politicians and police officials; the alternative underestimates the role of state representatives, describes the smuggling as more decentralised and chaotic and emphasises the role of organised crime gangs and radical Islamic organisations. Based on the interviews in the field conducted in January-March 2012, this paper analyses these alternative perspectives and the empirical evidence supporting these views. It highlights methodological problems relating to research on similar issues, elucidates networks of smuggling and their links with politics and reflects on complexities in addressing these challenges.

Prevention of the use of legal trafficking for nuclear material and radioactive sources smuggling. Keynote address/session 9

International Nuclear Information System (INIS)

Kravchenko, N.

2001-01-01

Full text: Countries like Russia, which have a large nuclear industry, export a significant number of radioactive sources and substances. Some of them are nuclear material. In general, it is the task of the customs inspectors to verify that the content of the shipment is in agreement with the declaration (as safeguards inspectors verify operators declarations). In case of other goods, this is easy. The consignment can be opened and the content can be seen and compared with the declaration. In the case of radioactive shipments this cannot be done. The radioactive substance is in a shielded container and opening is often only possible in a hot cell. Opening of the package and measurement of the removed source in presence of the customs inspector is impossible because the customs control begins only after the declaration has been registered. Therefore, the Russian customs authorities have contracted a company to develop a gamma spectrometer, which can be used to verify the source, even if inside the shielded shipping container. Throughout the country - where many shipments or receivables take place - there are 18 customs offices, equipped with gamma spectrometers and special software. If a container arrives for customs inspection, its design is called from a database. Then the gamma spectrum outside the container is measured and the measured gamma peak energy and intensity is compared with the expected, which is calculated by software based on the design information of the container. This approach works well. Several cases were already discovered in Russia, where there were attempts to use legal shipments for smuggling radioactive sources. I would like to mention some technical problems concerning control of legal export and import of radioactive sources: a) There are not enough commercial suppliers which offer the needed equipment; because of lack of competition prices for the equipment are too high. b) Presently available equipment is mainly based on HPGE cooled

An individual or group attempting to smuggle nuclear material out of a country has a choice of what border crossing to use and how to do it. If it is possible to think like a smuggler and determine what preferences one would have, then we could protect those smuggler-preferred border crossings first. Thinking like a smuggler requires that one understand a host of things: who is likely to smuggle and what might they have obtained, where they might have gotten it, and where they would like to deliver or sell it, how they will attempt to pass customs, how they might travel on both sides of the border, and what influences they might have on customs officials. After collecting data on criminology, geography, and much else, it is necessary to paste the data together into scenarios to ensure that self-consistent smuggling plans are created. These lead to counter-smuggling opportunities. Smuggling by amateurs turns out to be of a different class than professional smuggling, and needs to be countered differently. This work also assists in formulating key policy questions useful to guide counter-smuggling efforts. This methodology was developed for DOE/NN-43 for assistance with prioritization within the Second Line of Defense program.

Norway has not traditionally maintained any defence against smuggling of nuclear material. The 1993/94 report to Parliament on nuclear activities in areas adjacent to Norway mentioned the risk of such smuggling in the context of non-proliferation. In the light of this perceived risk a contact group was established with representatives from the Norwegian customs administration, police, armed forces and National Protection Authority. The group today has responsibility for the introduction of countermeasures against nuclear material smuggling in Norway. Another measure was establishment of Norwegian measurement facilities to combat smuggling of nuclear material. There arrangements are based on three lines of defence. The first will typically be the individual officer, the second, the special staff deployed following warnings or other indicators of smuggling, and the third would be any laboratory examination of specimens carried out in Norway or abroad

The Nuclear Smuggling International Technical Working Group: Making a difference in combating illicit trafficking

Niemeyer, S.; Koch, L.

2002-01-01

Full text: The ITWG was first formed in 1995 for the purpose of fostering international cooperation for combating illicit trafficking of nuclear materials. The initial focus for the ITWG was on the development of nuclear forensics to help answer attribution questions regarding nuclear materials of unknown origin. More recently, the ITWG has also expanded its focus to include detection of nuclear materials during transit. This paper presents some of the key developments by this group and their potential impact for combating nuclear smuggling. The initial focus of the ITWG was to write a status report on international cooperation on nuclear smuggling forensic analysis. This 26-page report summarized previous work on nuclear forensics and gave an initial analysis on prioritizing techniques and methods for forensic analysis regarding source and route attribution. This report was submitted to the G-8 countries, and shortly thereafter, nuclear forensics was endorsed at the Moscow Summit in April, 1996, as part of an illicit trafficking program. The work of the ITWG has also been noted at subsequent summit declarations, e.g. Cologne. The ITWG's primary goal is to develop a preferred approach to nuclear forensic investigations that is widely understood and accepted as credible. The technical elements include: 1) development of protocols for a) collection and preservation of evidence and b) for laboratory investigation, 2) prioritizing of techniques for forensic analysis, 3) development of forensic databanks to assist in interpretation, 4) executing inter-laboratory exercises, and 5) facilitating technical assistance to countries upon request. The development of protocols has been conducted jointly by law enforcement officials and laboratory scientists. A major focus during much of the past six years has been the development of a model action plan for nuclear forensics. This action plan lays out the elements that are needed in the instance that illicit nuclear material is

2015-02-01

Given the high risk and lengthy procedure of traditional drug development, drug repurposing is gaining more and more attention. Although many types of drug information have been used to repurpose drugs, drug-drug interaction data, which imply possible physiological effects or targets of drugs, remain unexploited. In this work, similarity of drug interaction was employed to infer similarity of the physiological effects or targets for the drugs. We collected 10,835 drug-drug interactions concerning 1074 drugs, and for 700 of them, drug similarity scores based on drug interaction profiles were computed and rendered using a drug association network with 589 nodes (drugs) and 2375 edges (drug similarity scores). The 589 drugs were clustered into 98 groups with Markov Clustering Algorithm, most of which were significantly correlated with certain drug functions. This indicates that the network can be used to infer the physiological effects of drugs. Furthermore, we evaluated the ability of this drug association network to predict drug targets. The results show that the method is effective for 317 of 561 drugs that have known targets. Comparison of this method with the structure-based approach shows that they are complementary. In summary, this study demonstrates the feasibility of drug repurposing based on drug-drug interaction data. © 2014 John Wiley & Sons A/S.

Modern forensic science has to deal not only with homicides and other traditional crimes but also with more global threats such as smuggling of nuclear materials, clandestine production of weapons of mass destruction, stockpiling of illicit drugs by state-controlled groups and war crimes. Forensic applications have always benefited from the use of advanced analytical tools that can characterise materials found at crime scenes. In this paper we will discuss the use of accelerator mass spectrometry as an ultra sensitive tool for the crime labs of the third millennium.

Modern forensic science has to deal not only with homicides and other traditional crimes but also with more global threats such as smuggling of nuclear materials, clandestine production of weapons of mass destruction, stockpiling of illicit drugs by state-controlled groups and war crimes. Forensic applications have always benefited from the use of advanced analytical tools that can characterise materials found at crime scenes. In this paper we will discuss the use of accelerator mass spectrometry as an ultra sensitive tool for the crime labs of the third millennium

Drug trafficking is an international problem. The prevalence of drug trafficking and newer concealing methods has been ever increasing. Body packing is described as using the abdominal or pelvic cavity for concealing illegal drugs. Body pushers smuggle illicit drugs by inserting them into rectum or vagina. These cases are either presented to the emergency departments as Body Packer Syndrome or as asymptomatic cases for observation, detained for alleged possession of contraband substances. We report a unique case of an asymptomatic white female who was detained at Mumbai International Airport under suspicion and brought to hospital for observation. X ray and CT scan examination revealed 7 wrapped packets in gastrointestinal track and 1 large packet in vagina. A case of female body packer using multiple modalities of concealment especially in vagina is rare in India so it is becomes imperative to present this case in the light of body packing and body pushing of contraband substances.

Due to international commerce, cross-border conflicts, and corruption, a holistic, information driven, approach to border security is required to best understand how resources should be applied to affect sustainable improvements in border security. The ability to transport goods and people by land, sea, and air across international borders with relative ease for legitimate commercial purposes creates a challenging environment to detect illicit smuggling activities that destabilize national level border security. Smuggling activities operated for profit or smuggling operations driven by cross border conflicts where militant or terrorist organizations facilitate the transport of materials and or extremists to advance a cause add complexity to smuggling interdiction efforts. Border security efforts are further hampered when corruption thwarts interdiction efforts or reduces the effectiveness of technology deployed to enhance border security. These issues necessitate the implementation of a holistic approach to border security that leverages all available data. Large amounts of information found in hundreds of thousands of documents can be compiled to assess national or regional borders to identify variables that influence border security. Location data associated with border topics of interest may be extracted and plotted to better characterize the current border security environment for a given country or region. This baseline assessment enables further analysis, but also documents the initial state of border security that can be used to evaluate progress after border security improvements are made. Then, border security threats are prioritized via a systems analysis approach. Mitigation factors to address risks can be developed and evaluated against inhibiting factor such as corruption. This holistic approach to border security helps address the dynamic smuggling interdiction environment where illicit activities divert to a new location that provides less resistance

International dimension of illicit trafficking in nuclear and other radioactive material

Full text: Illicit trafficking in nuclear and other radioactive material is primarily associated with Russia and other former Soviet republics. Indeed, with the collapse of the former Soviet Union (FSU) in 1991, hundreds of tons of weapons-usable nuclear material and thousands of radiation sources were left without adequate control and protection, thus posing a risk for sabotage, theft and diversion. Out of 700 illicit trafficking incidents recorded in the Stanford's database on nuclear smuggling, theft and orphan radiation sources (DSTO), over 450 either took place in the former Soviet Union or involved material that had reportedly originated from the FSU. In the period 1992-1994, Western and Eastern Europe were heavily affected by the inflow of nuclear material smuggled from the FSU. Since then, various measures were taken by the European countries and former Soviet republics to prevent the trafficking of radioactive substances ranging from the improvement of physical security at nuclear facilities to the installation of detection equipment at international borders. However, although the number of illicit trafficking incidents in Western Europe has decreased dramatically since 1994 and the overall annual number of such cases has been lower than in 1994, evidence suggests that diverted nuclear material is still being smuggled out of the FSU. An increased number of interceptions of nuclear and other radioactive material in the Caucasus, Turkey and Central Asia, well-known for their drugs and arms smuggling routes, over the past three years demonstrates that the material may now be moving south rather than west. This is particularly alarming considering the proximity of three countries to the potential end-users of nuclear and other radioactive material, such as AI Qaida terrorist network and aspiring nuclear weapon states in the Middle East. Although the FSU remains the major potential source of nuclear and other radioactive material, it is not the only one. Thefts

Full Text Available Smuggling drugs by swallowing or inserting into a body cavity is not only a serious and growing international crime, but can also lead to lethal medical complications. The most common cause of death in ‘body packers', people transporting drugs by ingesting a packet into the gastrointestinal tract, is acute drug toxicity from a ruptured packet. However, more than 30 years after the initial report of body packing, there is still no definitive treatment protocol for the management of this patient group. The treatment strategy is determined according to the particular condition of the patient and the clinical experience of the treatment center. Surgical intervention is also less common now, due to both the use of improved packaging materials among smugglers and a shift towards a more conservative medical approach. Herein, we report a case of toxicity from ingested packets of cocaine that leaked and, despite surgery, resulted in exitus of the patient.

　Elderly patients often suffer from a variety of diseases and therefore may be prescribed several kinds of drugs. Interactions between these drugs may cause problems in some patients. Guidelines for drug interactions were released on July 8, 2014 "Drug Interaction Guideline for Drug Development and Labeling Recommendations (Final Draft)". These guidelines include the theoretical basis for evaluating the mechanisms of drug interaction, the possible extent of drug interactions, and take into consideration special populations (e.g., infants, children, elderly patients, patients with hepatic or renal dysfunction, and subjects with minor deficient alleles for drug metabolizing enzymes and drug transporters). In this symposium article, I discuss this last special population: altered drug metabolism and drug interactions in subjects with minor alleles of genes encoding deficient drug metabolizing enzymes. I further discuss a drug label for eliglustat (Cerdelga) with instructions for patients with ultra-rapid, extensive, intermediate, and poor metabolizer phenotypes that arise from different CYP2D6 gene alleles.

Anthracyclines and taxanes are commonly used in the treatment of breast cancer. However, tumor resistance to these drugs often develops, possibly due to overexpression of drug transporters. It remains unclear whether drug resistance in vitro occurs at clinically relevant doses of chemotherapy drugs and whether both the onset and magnitude of drug resistance can be temporally and causally correlated with the enhanced expression and activity of specific drug transporters. To address these issues, MCF-7 cells were selected for survival in increasing concentrations of doxorubicin (MCF-7 DOX-2 ), epirubicin (MCF-7 EPI ), paclitaxel (MCF-7 TAX-2 ), or docetaxel (MCF-7 TXT ). During selection cells were assessed for drug sensitivity, drug uptake, and the expression of various drug transporters. In all cases, resistance was only achieved when selection reached a specific threshold dose, which was well within the clinical range. A reduction in drug uptake was temporally correlated with the acquisition of drug resistance for all cell lines, but further increases in drug resistance at doses above threshold were unrelated to changes in cellular drug uptake. Elevated expression of one or more drug transporters was seen at or above the threshold dose, but the identity, number, and temporal pattern of drug transporter induction varied with the drug used as selection agent. The pan drug transporter inhibitor cyclosporin A was able to partially or completely restore drug accumulation in the drug-resistant cell lines, but had only partial to no effect on drug sensitivity. The inability of cyclosporin A to restore drug sensitivity suggests the presence of additional mechanisms of drug resistance. This study indicates that drug resistance is achieved in breast tumour cells only upon exposure to concentrations of drug at or above a specific selection dose. While changes in drug accumulation and the expression of drug transporters does occur at the threshold dose, the magnitude of

The expanded use of multiple drugs has increased the occurrence of adverse drug reactions (ADRs) induced by drug-drug interactions (DDIs). However, such reactions are typically not observed in clinical drug-development studies because most of them focus on single-drug therapies. ADR reporting systems collect information on adverse health effects caused by both single drugs and DDIs. A major challenge is to unambiguously identify the effects caused by DDIs and to attribute them to specific drug interactions. A computational method that provides prospective predictions of potential DDI-induced ADRs will help to identify and mitigate these adverse health effects. We hypothesize that drug-protein interactions can be used as independent variables in predicting ADRs. We constructed drug pair-protein interaction profiles for ~800 drugs using drug-protein interaction information in the public domain. We then constructed statistical models to score drug pairs for their potential to induce ADRs based on drug pair-protein interaction profiles. We used extensive clinical database information to construct categorical prediction models for drug pairs that are likely to induce ADRs via synergistic DDIs and showed that model performance deteriorated only slightly, with a moderate amount of false positives and false negatives in the training samples, as evaluated by our cross-validation analysis. The cross validation calculations showed an average prediction accuracy of 89% across 1,096 ADR models that captured the deleterious effects of synergistic DDIs. Because the models rely on drug-protein interactions, we made predictions for pairwise combinations of 764 drugs that are currently on the market and for which drug-protein interaction information is available. These predictions are publicly accessible at http://avoid-db.bhsai.org . We used the predictive models to analyze broader aspects of DDI-induced ADRs, showing that ~10% of all combinations have the potential to induce ADRs

There are few studies examining both drug-drug and drug-disease interactions in older adults. Therefore, the objective of this study was to describe the prevalence of potential drug-drug and drug-disease interactions and associated factors in community-dwelling older adults. This cross-sectional study included 3055 adults aged 70-79 without mobility limitations at their baseline visit in the Health Aging and Body Composition Study conducted in the communities of Pittsburgh PA and Memphis TN, USA. The outcome factors were potential drug-drug and drug-disease interactions as per the application of explicit criteria drawn from a number of sources to self-reported prescription and non-prescription medication use. Over one-third of participants had at least one type of interaction. Approximately one quarter (25·1%) had evidence of had one or more drug-drug interactions. Nearly 10·7% of the participants had a drug-drug interaction that involved a non-prescription medication. % The most common drug-drug interaction was non-steroidal anti-inflammatory drugs (NSAIDs) affecting antihypertensives. Additionally, 16·0% had a potential drug-disease interaction with 3·7% participants having one involving non-prescription medications. The most common drug-disease interaction was aspirin/NSAID use in those with history of peptic ulcer disease without gastroprotection. Over one-third (34·0%) had at least one type of drug interaction. Each prescription medication increased the odds of having at least one type of drug interaction by 35-40% [drug-drug interaction adjusted odds ratio (AOR) = 1·35, 95% confidence interval (CI) = 1·27-1·42; drug-disease interaction AOR = 1·30; CI = 1·21-1·40; and both AOR = 1·45; CI = 1·34-1·57]. A prior hospitalization increased the odds of having at least one type of drug interaction by 49-84% compared with those not hospitalized (drug-drug interaction AOR = 1·49, 95% CI = 1·11-2·01; drug-disease interaction AOR = 1·69, CI = 1·15-2�

Computational prediction of drug-drug interactions based on drugs functional similarities.

Therapeutic activities of drugs are often influenced by co-administration of drugs that may cause inevitable drug-drug interactions (DDIs) and inadvertent side effects. Prediction and identification of DDIs are extremely vital for the patient safety and success of treatment modalities. A number of computational methods have been employed for the prediction of DDIs based on drugs structures and/or functions. Here, we report on a computational method for DDIs prediction based on functional similarity of drugs. The model was set based on key biological elements including carriers, transporters, enzymes and targets (CTET). The model was applied for 2189 approved drugs. For each drug, all the associated CTETs were collected, and the corresponding binary vectors were constructed to determine the DDIs. Various similarity measures were conducted to detect DDIs. Of the examined similarity methods, the inner product-based similarity measures (IPSMs) were found to provide improved prediction values. Altogether, 2,394,766 potential drug pairs interactions were studied. The model was able to predict over 250,000 unknown potential DDIs. Upon our findings, we propose the current method as a robust, yet simple and fast, universal in silico approach for identification of DDIs. We envision that this proposed method can be used as a practical technique for the detection of possible DDIs based on the functional similarities of drugs. Copyright © 2017.

2014-12-01

The aim of the present work was to perform a systematic review of drug metabolism, transport, pharmacokinetics, and DDI data available in the NDAs approved by the FDA in 2013, using the University of Washington Drug Interaction Database, and to highlight significant findings. Among 27 NMEs approved, 22 (81%) were well characterized with regard to drug metabolism, transport, or organ impairment, in accordance with the FDA drug interaction guidance (2012) and were fully analyzed in this review. In vitro, a majority of the NMEs were found to be substrates or inhibitors/inducers of at least one drug metabolizing enzyme or transporter. However, in vivo, only half (n = 11) showed clinically relevant drug interactions, with most related to the NMEs as victim drugs and CYP3A being the most affected enzyme. As perpetrators, the overall effects for NMEs were much less pronounced, compared with when they served as victims. In addition, the pharmacokinetic evaluation in patients with hepatic or renal impairment provided useful information for further understanding of the drugs' disposition.

Atreya, Ravi V; Sun, Jingchun; Zhao, Zhongming

2013-01-01

Drug addiction is a complex and chronic mental disease, which places a large burden on the American healthcare system due to its negative effects on patients and their families. Recently, network pharmacology is emerging as a promising approach to drug discovery by integrating network biology and polypharmacology, allowing for a deeper understanding of molecular mechanisms of drug actions at the systems level. This study seeks to apply this approach for investigation of illicit drugs and their targets in order to elucidate their interaction patterns and potential secondary drugs that can aid future research and clinical care. In this study, we extracted 188 illicit substances and their related information from the DrugBank database. The data process revealed 86 illicit drugs targeting a total of 73 unique human genes, which forms an illicit drug-target network. Compared to the full drug-target network from DrugBank, illicit drugs and their target genes tend to cluster together and form four subnetworks, corresponding to four major medication categories: depressants, stimulants, analgesics, and steroids. External analysis of Anatomical Therapeutic Chemical (ATC) second sublevel classifications confirmed that the illicit drugs have neurological functions or act via mechanisms of stimulants, opioids, and steroids. To further explore other drugs potentially having associations with illicit drugs, we constructed an illicit-extended drug-target network by adding the drugs that have the same target(s) as illicit drugs to the illicit drug-target network. After analyzing the degree and betweenness of the network, we identified hubs and bridge nodes, which might play important roles in the development and treatment of drug addiction. Among them, 49 non-illicit drugs might have potential to be used to treat addiction or have addictive effects, including some results that are supported by previous studies. This study presents the first systematic review of the network

Body Packing and Its Radiologic Manifestations: A Review Article

International Nuclear Information System (INIS)

Shahnazi, Makhtoom; Sanei Taheri, Morteza; Pourghorban, Ramin

2011-01-01

Body packing is described as using the abdominal or pelvic cavity for concealing illegal drugs. Leakage from the packets may cause catastrophic effects on smugglers and medical history is not reliable in these patients. Moreover, new sophisticated smuggling techniques make it imperative that radiologists and emergency physicians understand and familiarize themselves with the different radiological manifestations of ingested drug packets. Currently, there is no gold standard for imaging patients suspected of body packing; nevertheless, computed tomography (CT) seems to be the best modality for packet detection and unenhanced CT without bowel preparation is a reliable technique for detection of ingested packets. On abdominal radiography, packets may be visualized as oval or round radiopaque foreign bodies surrounded by a gas halo. In the literature, sensitivity of abdominal radiography is reported from 74% to 100%. Visualization of the drug packets may be strikingly hampered by administration of oral or intravenous contrast medium in abdomino-pelvic CT; hence, contrast-enhanced CT does not seem to be a suitable modality for searching the ingested packets in suspicious smugglers

Aptamers as Both Drugs and Drug-Carriers

Directory of Open Access Journals (Sweden)

Md. Ashrafuzzaman

2014-01-01

Full Text Available Aptamers are short nucleic acid oligos. They may serve as both drugs and drug-carriers. Their use as diagnostic tools is also evident. They can be generated using various experimental, theoretical, and computational techniques. The systematic evolution of ligands by exponential enrichment which uses iterative screening of nucleic acid libraries is a popular experimental technique. Theory inspired methodology entropy-based seed-and-grow strategy that designs aptamer templates to bind specifically to targets is another one. Aptamers are predicted to be highly useful in producing general drugs and theranostic drugs occasionally for certain diseases like cancer, Alzheimer’s disease, and so on. They bind to various targets like lipids, nucleic acids, proteins, small organic compounds, and even entire organisms. Aptamers may also serve as drug-carriers or nanoparticles helping drugs to get released in specific target regions. Due to better target specific physical binding properties aptamers cause less off-target toxicity effects. Therefore, search for aptamer based drugs, drug-carriers, and even diagnostic tools is expanding fast. The biophysical properties in relation to the target specific binding phenomena of aptamers, energetics behind the aptamer transport of drugs, and the consequent biological implications will be discussed. This review will open up avenues leading to novel drug discovery and drug delivery.

Drug-Target Kinetics in Drug Discovery.

Science.gov (United States)

Tonge, Peter J

2018-01-17

The development of therapies for the treatment of neurological cancer faces a number of major challenges including the synthesis of small molecule agents that can penetrate the blood-brain barrier (BBB). Given the likelihood that in many cases drug exposure will be lower in the CNS than in systemic circulation, it follows that strategies should be employed that can sustain target engagement at low drug concentration. Time dependent target occupancy is a function of both the drug and target concentration as well as the thermodynamic and kinetic parameters that describe the binding reaction coordinate, and sustained target occupancy can be achieved through structural modifications that increase target (re)binding and/or that decrease the rate of drug dissociation. The discovery and deployment of compounds with optimized kinetic effects requires information on the structure-kinetic relationships that modulate the kinetics of binding, and the molecular factors that control the translation of drug-target kinetics to time-dependent drug activity in the disease state. This Review first introduces the potential benefits of drug-target kinetics, such as the ability to delineate both thermodynamic and kinetic selectivity, and then describes factors, such as target vulnerability, that impact the utility of kinetic selectivity. The Review concludes with a description of a mechanistic PK/PD model that integrates drug-target kinetics into predictions of drug activity.

Neutron activation analysis in forensic investigations. Trace elements characterization of cigarettes

Giordani, L.; Rizzio, E.; Brandone, A.

2005-01-01

Police investigations of the Italian Ministry of Treasury Police involving the illicit sale of tobacco lead to the confiscation of large quantities of smuggled cigarettes. Thousands of tons of cigarettes of different manufacturers are sequestrated yearly in many regions of Italy and different criminal organizations have been identified as unlawful importers. In order to verify whether the recovered smuggled lots of cigarettes come from the official manufacturers, or they have produced illicitly, usually chemical analysis are carried out. By the determination of trace elements content, specific information can be obtained by comparing different brands of cigarettes and different batches of tobacco. Samples of tobacco of cigarettes manufactured by the Italian State Monopoly, taken as 'reference samples', have been compared with those of illicit origin. Elements such as Co, Br, Cr and Sc have been found to be useful for the selective characterization. The results, submitted to statistical elaboration, provided important information on the origin of smuggled cigarettes. (author)

Pharmacodynamics and common drug-drug interactions of the third-generation antiepileptic drugs.

Science.gov (United States)

Stefanović, Srđan; Janković, Slobodan M; Novaković, Milan; Milosavljević, Marko; Folić, Marko

2018-02-01

Anticonvulsants that belong to the third generation are considered as 'newer' antiepileptic drugs, including: eslicarbazepine acetate, lacosamide, perampanel, brivaracetam, rufinamide and stiripentol. Areas covered: This article reviews pharmacodynamics (i.e. mechanisms of action) and clinically relevant drug-drug interactions of the third-generation antiepileptic drugs. Expert opinion: Newer antiepileptic drugs have mechanisms of action which are not shared with the first and the second generation anticonvulsants, like inhibition of neurotransmitters release, blocking receptors for excitatory amino acids and new ways of sodium channel inactivation. New mechanisms of action increase chances of controlling forms of epilepsy resistant to older anticonvulsants. Important advantage of the third-generation anticonvulsants could be their little propensity for interactions with both antiepileptic and other drugs observed until now, making prescribing much easier and safer. However, this may change with new studies specifically designed to discover drug-drug interactions. Although the third-generation antiepileptic drugs enlarged therapeutic palette against epilepsy, 20-30% of patients with epilepsy is still treatment-resistant and need new pharmacological approach. There is great need to explore all molecular targets that may directly or indirectly be involved in generation of seizures, so a number of candidate compounds for even newer anticonvulsants could be generated.

Target-mediated drug disposition with drug-drug interaction, Part I: single drug case in alternative formulations.

Science.gov (United States)

Koch, Gilbert; Jusko, William J; Schropp, Johannes

2017-02-01

Target-mediated drug disposition (TMDD) describes drug binding with high affinity to a target such as a receptor. In application TMDD models are often over-parameterized and quasi-equilibrium (QE) or quasi-steady state (QSS) approximations are essential to reduce the number of parameters. However, implementation of such approximations becomes difficult for TMDD models with drug-drug interaction (DDI) mechanisms. Hence, alternative but equivalent formulations are necessary for QE or QSS approximations. To introduce and develop such formulations, the single drug case is reanalyzed. This work opens the route for straightforward implementation of QE or QSS approximations of DDI TMDD models. The manuscript is the first part to introduce DDI TMDD models with QE or QSS approximations.

Drug abuse: newly-emerging drugs and trends.

Drug abusers have access to new, more potent compounds that evade existing laws by virtue of their novel chemical structures. These drugs are available for purchase at stores and over the internet. The drugs are not illegal because they are so new that laws have not yet been passed to ban them. These drugs are leading to emergency department visits for cardiovascular, neurologic, and psychiatric complications. Standard drug screens are not designed to detect these new substances. The internet provides access to drugs for substance abusers but also provides physicians speed of access to the habits of substance abusers.

Indolealkylamines: biotransformations and potential drug-drug interactions.

Science.gov (United States)

Yu, Ai-Ming

2008-06-01

Indolealkylamine (IAA) drugs are 5-hydroxytryptamine (5-HT or serotonin) analogs that mainly act on the serotonin system. Some IAAs are clinically utilized for antimigraine therapy, whereas other substances are notable as drugs of abuse. In the clinical evaluation of antimigraine triptan drugs, studies on their biotransformations and pharmacokinetics would facilitate the understanding and prevention of unwanted drug-drug interactions (DDIs). A stable, principal metabolite of an IAA drug of abuse could serve as a useful biomarker in assessing intoxication of the IAA substance. Studies on the metabolism of IAA drugs of abuse including lysergic acid amides, tryptamine derivatives and beta-carbolines are therefore emerging. An important role for polymorphic cytochrome P450 2D6 (CYP2D6) in the metabolism of IAA drugs of abuse has been revealed by recent studies, suggesting that variations in IAA metabolism, pharmaco- or toxicokinetics and dynamics can arise from distinct CYP2D6 status, and CYP2D6 polymorphism may represent an additional risk factor in the use of these IAA drugs. Furthermore, DDIs with IAA agents could occur additively at the pharmaco/toxicokinetic and dynamic levels, leading to severe or even fatal serotonin toxicity. In this review, the metabolism and potential DDIs of these therapeutic and abused IAA drugs are described.

6-mercaptopurine and daunorubicin double drug liposomes-preparation, drug-drug interaction and characterization.

Science.gov (United States)

Agrawal, Vineet; Paul, Manash K; Mukhopadhyay, Anup K

2005-01-01

This article addresses and investigates the dual incorporation of daunorubicin (DR) and 6-mercaptopurine (6-MP) in liposomes for better chemotherapy. These drugs are potential candidates for interaction due to the quinone (H acceptor) and hydroxyl (H donor) groups on DR and 6-MP, respectively. Interactions between the two drugs in solution were monitored by UV/Vis and fluorescence spectroscopy. Interaction between the two drugs inside the liposomes was evaluated by HPLC (for 6-MP) and by fluorescence spectroscopy (for daunorubicin) after phospholipase-mediated liposome lysis. Our results provide evidence for the lack of interaction between the two drugs in solution and in liposomes. The entrapment efficiencies of 6-MP in the neutral Phosphatidyl choline (PC):Cholesterol (Chol):: 2:1 and anionic PC:Chol:Cardiolipin (CL) :: 4:5:1 single and double drug liposomes were found to be 0.4% and 1.5% (on average), respectively. The entrapment efficiencies of DR in the neutral and anionic double drug liposomes were found to be 55% and 31%, respectively. The corresponding entrapment of daunorubicin in the single drug liposomes was found to be 62% on average. Our thin layer chromatography (TLC) and transmission electron microscopy (TEM) results suggest stability of lipid and liposomes, thus pointing plausible existence of double drug liposomes. Cytotoxicity experiments were performed by using both single drug and double drug liposomes. By comparing the results of phase contrast and fluorescence microscopy, it was observed that the double drug liposomes were internalized in the jurkat and Hut78 (highly resistant cell line) leukemia cells as viewed by the fluorescence of daunorubicin. The cytotoxicity was dose dependent and had shown a synergistic effect when double drug liposome was used.

Drug-drug interactions between anti-retroviral therapies and drugs of abuse in HIV systems.

Science.gov (United States)

Kumar, Santosh; Rao, P S S; Earla, Ravindra; Kumar, Anil

2015-03-01

Substance abuse is a common problem among HIV-infected individuals. Importantly, addictions as well as moderate use of alcohol, smoking, or other illicit drugs have been identified as major reasons for non-adherence to antiretroviral therapy (ART) among HIV patients. The literature also suggests a decrease in the response to ART among HIV patients who use these substances, leading to failure to achieve optimal virological response and increased disease progression. This review discusses the challenges with adherence to ART as well as observed drug interactions and known toxicities with major drugs of abuse, such as alcohol, smoking, methamphetamine, cocaine, marijuana, and opioids. The lack of adherence and drug interactions potentially lead to decreased efficacy of ART drugs and increased ART, and drugs of abuse-mediated toxicity. As CYP is the common pathway in metabolizing both ART and drugs of abuse, we discuss the possible involvement of CYP pathways in such drug interactions. We acknowledge that further studies focusing on common metabolic pathways involving CYP and advance research in this area would help to potentially develop novel/alternate interventions and drug dose/regimen adjustments to improve medication outcomes in HIV patients who consume drugs of abuse.

A drug's life: the pathway to drug approval.

Science.gov (United States)

Keng, Michael K; Wenzell, Candice M; Sekeres, Mikkael A

2013-10-01

In the United States, drugs and medical devices are regulated by the US Food and Drug Administration (FDA). A drug must undergo rigorous testing prior to marketing to and medical use by the general public. The FDA grants marketing approval for drug products based on a comprehensive review of safety and efficacy data. This review article explains the history behind the establishment of the FDA and examines the historical legislation and approval processes for drugs, specifically in the fields of medical oncology and hematology. The agents imatinib (Gleevec, Novartis) and decitabine (Dacogen, Eisai) are used to illustrate both the current FDA regulatory process-specifically the orphan drug designation and accelerated approval process-and why decitabine failed to gain an indication for acute myeloid leukemia. The purpose and construct of the Oncologic Drugs Advisory Committee are also discussed, along with examples of 2 renal cell cancer drugs-axitinib (Inlyta, Pfizer) and tivozanib-that used progression-free survival as an endpoint. Regulatory approval of oncology drugs is the cornerstone of the development of new treatment agents and modalities, which lead to improvements in the standard of cancer care. The future landscape of drug development and regulatory approval will be influenced by the new breakthrough therapy designation, and choice of drug will be guided by genomic insights.

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

Development smuggling and confiscation of illicit radioactive materials demands taking into account its financial implications. The real beneficiaries of smuggling are often difficult to identify. Generally the violation cases are impossible to solve. Who would pay? How the costs of detection, analysis and decontamination could be covered. One of the primary solutions could be better charge of different parties (prisoners). It could as well be the responsibility of involved parties (transporters, enterprises, etc.). Another possibility would be to apply the principle of responsibility for payment by the party responsible for contamination

Drug-drug interaction (DDI) screening systems report potential DDIs. This study aimed to find the prevalence of probable DDI-related adverse drug reactions (ADRs) and compare the clinical usefulness of different DDI screening systems to prevent or warn against these ADRs. A prospective cohort study was conducted in patients urgently admitted to medical departments. Potential DDIs were checked using Complete Drug Interaction®, Lexicomp® Online™, and Drug Interaction Checker®. The study team identified the patients with probable clinically relevant DDI-related ADRs on admission, the causality of which was assessed using the Drug Interaction Probability Scale (DIPS). Sensitivity, specificity, and positive and negative predictive values of screening systems to prevent or warn against probable DDI-related ADRs were evaluated. Overall, 50 probable clinically relevant DDI-related ADRs were found in 37 out of 795 included patients taking at least two drugs, most common of them were bleeding, hyperkalemia, digitalis toxicity, and hypotension. Complete Drug Interaction showed the best sensitivity (0.76) for actual DDI-related ADRs, followed by Lexicomp Online (0.50), and Drug Interaction Checker (0.40). Complete Drug Interaction and Drug Interaction Checker had positive predictive values of 0.07; Lexicomp Online had 0.04. We found no difference in specificity and negative predictive values among these systems. DDI screening systems differ significantly in their ability to detect probable clinically relevant DDI-related ADRs in terms of sensitivity and positive predictive value.

Drug-Drug/Drug-Excipient Compatibility Studies on Curcumin using Non-Thermal Methods

Directory of Open Access Journals (Sweden)

Moorthi Chidambaram

2014-05-01

Full Text Available Purpose: Curcumin is a hydrophobic polyphenol isolated from dried rhizome of turmeric. Clinical usefulness of curcumin in the treatment of cancer is limited due to poor aqueous solubility, hydrolytic degradation, metabolism, and poor oral bioavailability. To overcome these limitations, we proposed to fabricate curcumin-piperine, curcumin-quercetin and curcumin-silibinin loaded polymeric nanoformulation. However, unfavourable combinations of drug-drug and drug-excipient may result in interaction and rises the safety concern. Hence, the present study was aimed to assess the interaction of curcumin with excipients used in nanoformulations. Methods: Isothermal stress testing method was used to assess the compatibility of drug-drug/drug-excipient. Results: The combination of curcumin-piperine, curcumin-quercetin, curcumin-silibinin and the combination of other excipients with curcumin, piperine, quercetin and silibinin have not shown any significant physical and chemical instability. Conclusion: The study concludes that the curcumin, piperine, quercetin and silibinin is compatible with each other and with other excipients.

Full Text Available Miriam Boeri, Thor Whalen, Benjamin Tyndall, Ellen BallardKennesaw State University, Department of Sociology and Criminal Justice, Kennesaw GA, USAAbstract: To better understand patterns of drug use trajectories over time, it is essential to have standard measures of change. Our goal here is to introduce measures we developed to quantify change in drug use behaviors. A secondary goal is to provide effective visualizations of these trajectories for applied use. We analyzed data from a sample of 92 older drug users (ages 45 to 65 to identify transition patterns in drug use trajectories across the life course. Data were collected for every year since birth using a mixed methods design. The community-drawn sample of active and former users were 40% female, 50% African American, and 60% reporting some college or greater. Their life histories provided retrospective longitudinal data on the diversity of paths taken throughout the life course and changes in drug use patterns that occurred over time. Bayesian analysis was used to model drug trajectories displayed by innovative computer graphics. The mathematical techniques and visualizations presented here provide the foundation for future models using Bayesian analysis. In this paper we introduce the concepts of transition counts, transition rates and relapse/remission rates, and we describe how these measures can help us better understand drug use trajectories. Depicted through these visual tools, measurements of discontinuous patterns provide a succinct view of individual drug use trajectories. The measures we use on drug use data will be further developed to incorporate contextual influences on the drug trajectory and build predictive models that inform rehabilitation efforts for drug users. Although the measures developed here were conceived to better examine drug use trajectories, the applications of these measures can be used with other longitudinal datasets.Keywords: drug use, trajectory patterns

Drug interactions between common illicit drugs and prescription therapies.

Lindsey, Wesley T; Stewart, David; Childress, Darrell

2012-07-01

The aim was to summarize the clinical literature on interactions between common illicit drugs and prescription therapies. Medline, Iowa Drug Information Service, International Pharmaceutical Abstracts, EBSCO Academic Search Premier, and Google Scholar were searched from date of origin of database to March 2011. Search terms were cocaine, marijuana, cannabis, methamphetamine, amphetamine, ecstasy, N-methyl-3,4-methylenedioxymethamphetamine, methylenedioxymethamphetamine, heroin, gamma-hydroxybutyrate, sodium oxybate, and combined with interactions, drug interactions, and drug-drug interactions. This review focuses on established clinical evidence. All applicable full-text English language articles and abstracts found were evaluated and included in the review as appropriate. The interactions of illicit drugs with prescription therapies have the ability to potentiate or attenuate the effects of both the illicit agent and/or the prescription therapeutic agent, which can lead to toxic effects or a reduction in the prescription agent's therapeutic activity. Most texts and databases focus on theoretical or probable interactions due to the kinetic properties of the drugs and do not fully explore the pharmacodynamic and clinical implications of these interactions. Clinical trials with coadministration of illicit drugs and prescription drugs are discussed along with case reports that demonstrate a potential interaction between agents. The illicit drugs discussed are cocaine, marijuana, amphetamines, methylenedioxymethamphetamine, heroin, and sodium oxybate. Although the use of illicit drugs is widespread, there are little experimental or clinical data regarding the effects of these agents on common prescription therapies. Potential drug interactions between illicit drugs and prescription drugs are described and evaluated on the Drug Interaction Probability Scale by Horn and Hansten.

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.

2018-02-01

A drug's physical characteristics, such as colour, could be factors influencing its therapeutic effects. It is not well understood whether people's expectations on drug effects and efficacy are affected by colour, especially among Chinese population. This study was conducted to examine people's expectations on drug effects and efficacy on the basis of drug colour, and to reveal possible gender differences in colour-related drug expectations. Participants (n = 224) were asked to classify seven single-coloured and six two-coloured capsules into one of four categories of drug effects, and to indicate the strength of drug efficacy. It is found that all the coloured capsules yielded non-chance distributions in classifications of drug effects, with six single-coloured and four two-coloured capsules associated with specific drug effects. Colour also conveyed differential strengths of drug efficacy in general and in relation to specific drug effects. There were gender differences in drug expectations for some colours and colour combinations. Practitioner Summary: Drug colour was found to have impacts on perceived drug effects and efficacy. The findings from the present study can be used by ergonomics practitioners to design appropriate drug colours in support of drug differentiation, therapeutic effects and medication adherence.

Drug-drug interactions involving lysosomes: mechanisms and potential clinical implications.

Science.gov (United States)

Logan, Randall; Funk, Ryan S; Axcell, Erick; Krise, Jeffrey P

2012-08-01

Many commercially available, weakly basic drugs have been shown to be lysosomotropic, meaning they are subject to extensive sequestration in lysosomes through an ion trapping-type mechanism. The extent of lysosomal trapping of a drug is an important therapeutic consideration because it can influence both activity and pharmacokinetic disposition. The administration of certain drugs can alter lysosomes such that their accumulation capacity for co-administered and/or secondarily administered drugs is altered. In this review the authors explore what is known regarding the mechanistic basis for drug-drug interactions involving lysosomes. Specifically, the authors address the influence of drugs on lysosomal pH, volume and lipid processing. Many drugs are known to extensively accumulate in lysosomes and significantly alter their structure and function; however, the therapeutic and toxicological implications of this remain controversial. The authors propose that drug-drug interactions involving lysosomes represent an important potential source of variability in drug activity and pharmacokinetics. Most evaluations of drug-drug interactions involving lysosomes have been performed in cultured cells and isolated tissues. More comprehensive in vivo evaluations are needed to fully explore the impact of this drug-drug interaction pathway on therapeutic outcomes.

Political instability, conflicts and inequalities result into significant flows of people worldwide, moving to different countries in search of a better life, safety or to be reunited with their families. Irregular crossings into Europe via sea routes, despite not being new, have recently increased together with the loss of lives of people in the attempt to reach EU shores. This highlights the need to find ways to improve the understanding of what is happening at sea. This paper, intends to expand the knowledge available on practices among smugglers and contribute to early warning and maritime situational awareness. By identifying smuggling techniques and based on anomaly detection methods, behaviours of interest are modelled and one class support vector machines are used to classify unlabelled data and detect potential smuggling vessels. Nine vessels are identified as potentially carrying irregular migrants and refugees. Though, further inspection of the results highlights possible misclassifications caused by data gaps and limited knowledge on smuggling tactics. Accepted classifications are considered subject to further investigation by the authorities.

Increasing excise taxes in the presence of an illegal cigarette market: the 2011 Brazil tobacco tax reform

Directory of Open Access Journals (Sweden)

Roberto Magno Iglesias

Full Text Available ABSTRACT The Brazilian cigarette excise tax reform of 2011 increased tax rates significantly in the presence of a high proportion of illegal and cheap cigarettes contributing to total consumption. Prior to 2011, tobacco tax policy in Brazil had reduced excise tax share on consumer prices, for fear of smuggling. This report examines two hypotheses explaining why tax authorities changed direction. The first is related to lack of concern regarding smuggling in tobacco industry pricing behavior before 2011 (rather than reducing prices following tax reduction, legal companies increased net of tax prices above inflation and key costs. The second hypothesis regards inconsistent industry assessments of the size of the illicit market, which ultimately undermined the credibility of the industry with tax authorities. The author concludes that the 2011 reform was designed to revert the weakness of previous policies, and did indeed succeed. The post-2011 experience in Brazil indicates that increased cigarette excise taxes can increase government revenues and reduce smoking prevalence and consumption despite widespread smuggling of tobacco products.

Illegality of international population movements in Poland.

Science.gov (United States)

Okolski, M

2000-01-01

Until the beginning of the 1990s Poland did not receive foreign migrants. Thereafter, the situation changed dramatically. A large part of the inflow proved to be illegal migrants, many of whom were in transit to Western Europe. Although these movements gradually declined in the second half of the decade, some became increasingly identified with relatively sophisticated smuggling of people. Foreigners smuggled from the South to the West, together with the international criminal networks assisting them, became typical of the migratory movements of people in Central and Eastern Europe during the 1990s. This article seeks to describe illegal migration from the perspective of Poland, a country often perceived as a major transit area in the smuggling of persons to Western Europe. The conclusions draw on the findings of several surveys recently carried out in Poland. Basic concepts related to illegal migration are defined and juxtaposed, and various myths and stereotypes concerning it that most often stem from the paucity of empirical evidence are examined. Finally, the trends observed in Poland are interpreted within the larger context of contemporary European migration.

Orphan drugs: trends and issues in drug development.

Science.gov (United States)

Rana, Proteesh; Chawla, Shalini

2018-04-12

Research in rare diseases has contributed substantially toward the current understanding in the pathophysiology of the common diseases. However, medical needs of patients with rare diseases have always been neglected by the society and pharmaceutical industries based on their small numbers and unprofitability. The Orphan Drug Act (1983) was the first serious attempt to address the unmet medical needs for patients with rare diseases and to provide impetus for the pharmaceutical industry to promote orphan drug development. The process of drug development for rare diseases is no different from common diseases but involves significant cost and infrastructure. Further, certain aspect of drug research may not be feasible for the rare diseases. The drug-approving authority must exercise their scientific judgment and ensure due flexibility while evaluating data at various stages of orphan drug development. The emergence of patent cliff combined with the government incentives led the pharmaceutical industry to realize the good commercial prospects in developing an orphan drug despite the small market size. Indeed, many drugs that were given orphan designation ended up being blockbusters. The orphan drug market is projected to reach $178 billion by 2020, and the prospects of research and development in rare diseases appears to be quite promising and rewarding.

Summarizing the status of drugs in the market and examining the trend of drug research and development is important in drug discovery. In this study, we compared the drug targets and the market sales of the new molecular entities approved by the U.S. Food and Drug Administration from January 2000 to December 2009. Two networks, namely, the target-target and drug-drug networks, have been set up using the network analysis tools. The multi-target drugs have much more potential, as shown by the network visualization and the market trends. We discussed the possible reasons and proposed the rational strategies for drug research and development in the future.

Sucralfate, a complex of aluminium hydroxide with sulfated sucrose, forms a strong gastrointestinal tract (GIT) mucosal barrier with excellent anti-ulcer property. Because sucralfate does not undergo any significant oral absorption, sucralfate resides in the GIT for a considerable length of time. The unabsorbed sucralfate may alter the pharmacokinetics of the oral drugs by impeding its absorption and reducing the oral bioavailability. Because of the increased use of sucralfate, it was important to provide a reappraisal of the published clinical drug-drug interaction studies of sucralfate with scores of drugs. This review covers several category of drugs such as non-steroidal anti-inflammatory drugs, fluoroquinolones, histamine H2-receptor blockers, macrolides, anti-fungals, anti-diabetics, salicylic acid derivatives, steroidal anti-inflammatory drugs and provides pharmacokinetic data summary along with study design, objectives and key remarks. While the loss of oral bioavailability was significant for the fluoroquinolone class, it generally varied for other classes of drugs, suggesting that impact of the co-administration of sucralfate is manageable in clinical situations. Given the technology advancement in formulation development, it may be in order feasible to develop appropriate formulation strategies to either avoid or minimize the absorption-related issues when co-administered with sucralfate. It is recommended that consideration of both in vitro and preclinical studies may be in order to gauge the level of interaction of a drug with sucralfate. Such data may aid in the development of appropriate strategies to navigate the co-administration of sucralfate with other drugs in this age of polypharmacy.

Glutamatergic transmission in drug reward: implications for drug addiction.

D'Souza, Manoranjan S

2015-01-01

Individuals addicted to drugs of abuse such as alcohol, nicotine, cocaine, and heroin are a significant burden on healthcare systems all over the world. The positive reinforcing (rewarding) effects of the above mentioned drugs play a major role in the initiation and maintenance of the drug-taking habit. Thus, understanding the neurochemical mechanisms underlying the reinforcing effects of drugs of abuse is critical to reducing the burden of drug addiction in society. Over the last two decades, there has been an increasing focus on the role of the excitatory neurotransmitter glutamate in drug addiction. In this review, pharmacological and genetic evidence supporting the role of glutamate in mediating the rewarding effects of the above described drugs of abuse will be discussed. Further, the review will discuss the role of glutamate transmission in two complex heterogeneous brain regions, namely the nucleus accumbens (NAcc) and the ventral tegmental area (VTA), which mediate the rewarding effects of drugs of abuse. In addition, several medications approved by the Food and Drug Administration that act by blocking glutamate transmission will be discussed in the context of drug reward. Finally, this review will discuss future studies needed to address currently unanswered gaps in knowledge, which will further elucidate the role of glutamate in the rewarding effects of drugs of abuse.

Purpose: Curcumin is a hydrophobic polyphenol isolated from dried rhizome of turmeric. Clinical usefulness of curcumin in the treatment of cancer is limited due to poor aqueous solubility, hydrolytic degradation, metabolism, and poor oral bioavailability. To overcome these limitations, we proposed to fabricate curcumin-piperine, curcumin-quercetin and curcumin-silibinin loaded polymeric nanoformulation.

Hybrid nanostructured drug carrier with tunable and controlled drug release

International Nuclear Information System (INIS)

Depan, D.; Misra, R.D.K.

2012-01-01

We describe here a transformative approach to synthesize a hybrid nanostructured drug carrier that exhibits the characteristics of controlled drug release. The synthesis of the nanohybrid architecture involved two steps. The first step involved direct crystallization of biocompatible copolymer along the long axis of the carbon nanotubes (CNTs), followed by the second step of attachment of drug molecule to the polymer via hydrogen bonding. The extraordinary inorganic–organic hybrid architecture exhibited high drug loading ability and is physically stable even under extreme conditions of acidic media and ultrasonic irradiation. The temperature and pH sensitive characteristics of the hybrid drug carrier and high drug loading ability merit its consideration as a promising carrier and utilization of the fundamental aspects used for synthesis of other promising drug carriers. The higher drug release response during the application of ultrasonic frequency is ascribed to a cavitation-type process in which the acoustic bubbles nucleate and collapse releasing the drug. Furthermore, the study underscores the potential of uniquely combining CNTs and biopolymers for drug delivery. - Graphical abstract: Block-copolymer crystallized on carbon nanotubes (CNTs). Nanohybrid drug carrier synthesized by attaching doxorubicin (DOX) to polymer crystallized CNTs. Crystallized polymer on CNTs provide mechanical stability. Triggered release of DOX. Highlights: ► The novel synthesis of a hybrid nanostructured drug carrier is described. ► The drug carrier exhibits high drug loading ability and is physically stable. ► The high drug release is ascribed to a cavitation-type process.

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.

Brand-name drug, generic drug, orphan drug. Pharmacological therapy with biosimilar drugs - provision of due diligence in the treatment process.

Science.gov (United States)

Zajdel, Justyna; Zajdel, Radosław

2013-01-01

Due diligence in the process of provision of healthcare services refers, among other elements, to the application of pharmacological therapy at a time which offers the greatest chance for a successful outcome of treatment, i.e. for achieving the optimum expected effect understood as an improvement in the patient's health, reduction of health risks or elimination of the disease. However, due diligence may also refer to actions aimed at ensuring that neither the patient nor the healthcare payer is required to incur unreasonable costs in the process of treatment. The validity of that statement stems not only from normative acts but also from ethical standards laid down in the Medical Code of Ethics (Article 57 section 2). It often happens that the provision of optimal treatment calls for deviations from the formal provisions included in Summary Product Characteristics (SPCs), and the application of drugs that are bioequivalent to reference drugs, which translates into a significant reduction of costs. The present study addresses the problem of acceptability of a specific form of drug substitution consisting in the replacement of a reference drug with a generic drug. Also explored are legal aspects associated with the possibility of therapy based on "off-label use". The study reviews normative acts existing in the Polish and EU legislation. It also provides a clear definition of orphan drug, which has made it possible to make a distinction and investigate mutual relations between the concepts of brand-name (reference) drug, orphan drug and generic drug.

With substantial numbers of breast tumors showing or acquiring treatment resistance, it is of utmost importance to develop new agents for the treatment of the disease, to know their effectiveness against breast cancer and to understand their relationships with other drugs to best assign the right drug to the right patient. To achieve this goal drug screenings on breast cancer cell lines are a promising approach. In this study a large-scale drug screening of 37 compounds was performed on a panel of 42 breast cancer cell lines representing the main breast cancer subtypes. Clustering, correlation and pathway analyses were used for data analysis. We found that compounds with a related mechanism of action had correlated IC50 values and thus grouped together when the cell lines were hierarchically clustered based on IC50 values. In total we found six clusters of drugs of which five consisted of drugs with related mode of action and one cluster with two drugs not previously connected. In total, 25 correlated and four anti-correlated drug sensitivities were revealed of which only one drug, Sirolimus, showed significantly lower IC50 values in the luminal/ERBB2 breast cancer subtype. We found expected interactions but also discovered new relationships between drugs which might have implications for cancer treatment regimens.

Full Text Available The effect of drug on a person may be different than expected because that drug interacts with another drug the person is taking (drug-drug interaction, food, beverages, dietary supplements the person is consuming (drug-nutrient/food interaction or another disease the person has (drug-disease interaction. A drug interaction is a situation in which a substance affects the activity of a drug, i.e. the effects are increased or decreased, or they produce a new effect that neither produces on its own. These interactions may occur out of accidental misuse or due to lack of knowledge about the active ingredients involved in the relevant substances. Regarding food-drug interactions physicians and pharmacists recognize that some foods and drugs, when taken simultaneously, can alter the body's ability to utilize a particular food or drug, or cause serious side effects. Clinically significant drug interactions, which pose potential harm to the patient, may result from changes in pharmaceutical, pharmacokinetic, or pharmacodynamic properties. Some may be taken advantage of, to the benefit of patients, but more commonly drug interactions result in adverse drug events. Therefore it is advisable for patients to follow the physician and doctors instructions to obtain maximum benefits with least fooddrug interactions. The literature survey was conducted by extracting data from different review and original articles on general or specific drug interactions with food. This review gives information about various interactions between different foods and drugs and will help physicians and pharmacists prescribe drugs cautiously with only suitable food supplement to get maximum benefit for the patient.

Drugs used for treatment of rare diseases are known worldwide under the term of orphan drugs because pharmaceutical companies have not been interested in "adopting" them, that is in investing in research, developing and producing these drugs. This kind of policy has been justified by the fact that these drugs are targeted for small markets, that only a small number of patients is available for clinical trials, and that large investments are required for the development of drugs meant to treat diseases whose pathogenesis has not yet been clarified in majority of cases. The aim of this paper is to present previous and present status of orphan drugs in Serbia and other countries. THE BEGINNING OF ORPHAN DRUGS DEVELOPMENT: This problem was first recognized by Congress of the United States of America in January 1983, and when the "Orphan Drug Act" was passed, it was a turning point in the development of orphan drugs. This law provides pharmaceutical companies with a series of reliefs, both financial ones that allow them to regain funds invested into the research and development and regulatory ones. Seven years of marketing exclusivity, as a type of patent monopoly, is the most important relief that enables companies to make large profits. There are no sufficient funds and institutions to give financial support to the patients. It is therefore necessary to make health professionals much more aware of rare diseases in order to avoid time loss in making the right diagnosis and thus to gain more time to treat rare diseases. The importance of discovery, development and production of orphan drugs lies in the number of patients whose life quality can be improved significantly by administration of these drugs as well as in the number of potential survivals resulting from the treatment with these drugs.

Investigating drug repositioning opportunities in FDA drug labels through topic modeling.

2012-01-01

Drug repositioning offers an opportunity to revitalize the slowing drug discovery pipeline by finding new uses for currently existing drugs. Our hypothesis is that drugs sharing similar side effect profiles are likely to be effective for the same disease, and thus repositioning opportunities can be identified by finding drug pairs with similar side effects documented in U.S. Food and Drug Administration (FDA) approved drug labels. The safety information in the drug labels is usually obtained in the clinical trial and augmented with the observations in the post-market use of the drug. Therefore, our drug repositioning approach can take the advantage of more comprehensive safety information comparing with conventional de novo approach. A probabilistic topic model was constructed based on the terms in the Medical Dictionary for Regulatory Activities (MedDRA) that appeared in the Boxed Warning, Warnings and Precautions, and Adverse Reactions sections of the labels of 870 drugs. Fifty-two unique topics, each containing a set of terms, were identified by using topic modeling. The resulting probabilistic topic associations were used to measure the distance (similarity) between drugs. The success of the proposed model was evaluated by comparing a drug and its nearest neighbor (i.e., a drug pair) for common indications found in the Indications and Usage Section of the drug labels. Given a drug with more than three indications, the model yielded a 75% recall, meaning 75% of drug pairs shared one or more common indications. This is significantly higher than the 22% recall rate achieved by random selection. Additionally, the recall rate grows rapidly as the number of drug indications increases and reaches 84% for drugs with 11 indications. The analysis also demonstrated that 65 drugs with a Boxed Warning, which indicates significant risk of serious and possibly life-threatening adverse effects, might be replaced with safer alternatives that do not have a Boxed Warning.

Severe adverse drug reactions (ADRs) are the fourth leading cause of fatality in the U.S. with more than 100,000 deaths per year. As up to 30% of all ADRs are believed to be caused by drug-drug interactions (DDIs), typically mediated by cytochrome P450s, possibilities to predict DDIs from existing knowledge are important. We collected data from public sources on 1485, 2628, 4371, and 27,966 possible DDIs mediated by four cytochrome P450 isoforms 1A2, 2C9, 2D6, and 3A4 for 55, 73, 94, and 237 drugs, respectively. For each of these data sets, we developed and validated QSAR models for the prediction of DDIs. As a unique feature of our approach, the interacting drug pairs were represented as binary chemical mixtures in a 1:1 ratio. We used two types of chemical descriptors: quantitative neighborhoods of atoms (QNA) and simplex descriptors. Radial basis functions with self-consistent regression (RBF-SCR) and random forest (RF) were utilized to build QSAR models predicting the likelihood of DDIs for any pair of drug molecules. Our models showed balanced accuracy of 72-79% for the external test sets with a coverage of 81.36-100% when a conservative threshold for the model's applicability domain was applied. We generated virtually all possible binary combinations of marketed drugs and employed our models to identify drug pairs predicted to be instances of DDI. More than 4500 of these predicted DDIs that were not found in our training sets were confirmed by data from the DrugBank database.

Drug decriminalization and the price of illicit drugs.

Félix, Sónia; Portugal, Pedro

2017-01-01

This study is an empirical assessment of the impact of the drug decriminalization policy followed by Portugal in July 2001, on the price of illicit drugs. The analysis is performed using a difference-in-differences approach and the Synthetic Control Method in order to construct a synthetic control unit from a convex combination of countries. The results suggest that the prices of opiates and cocaine in the post-treatment period did not decrease in the sequence of the policy change. We conclude that the drug decriminalization policy seems to have caused no harm through lower illicit drugs prices, which would lead to higher drug usage and dependence.

Body packing is the ingestion or insertion in the human body of packed illicit substances. Over the last 20 years, drug smuggling has increased global and new means of transport of narcotics have emerged. Among these, the most frequent one is the gastrointestinal tract: from mouth to anus, vagina, and ears. Cocaine is one of the most traded drugs, followed by heroin. Condoms, latex gloves, and balloons are typically used as drug packets for retention in the body. There are different radiologic modalities to detect illicit drugs in body packing: Plain radiography, computed tomography (CT), ultrasound, and magnetic resonance. Current protocols recommend the use of radiography to confirm packet retention and, in case of doubt, the use of abdominal CT scan with reduced mAs. In case of packet rupture, catastrophic effects can occur. Management of patients carrying packets of drugs is a recurrent medico-legal problem. To improve diagnostic accuracy and prevent hazardous complications, radiologists and emergency physicians should be familiar with radiologic features of body packing. The radiologist plays both a social and a medico-legal role in their assessment, and it should not be limited only to the identification of the packages but must also provide accurate information about their number and their exact location. In this review, we focus on diagnostic errors and medico-legal issues related to the radiological assessment of body packers.

Perceived neighborhood illicit drug selling, peer illicit drug disapproval and illicit drug use among U.S. high school seniors

Science.gov (United States)

2014-01-01

Background This study examined associations between perceived neighborhood illicit drug selling, peer illicit drug disapproval and illicit drug use among a large nationally representative sample of U.S. high school seniors. Methods Data come from Monitoring the Future (2007–2011), an annual cross-sectional survey of U.S. high school seniors. Students reported neighborhood illicit drug selling, friend drug disapproval towards marijuana and cocaine use, and past 12-month and past 30-day illicit drug use (N = 10,050). Multinomial logistic regression models were fit to explain use of 1) just marijuana, 2) one illicit drug other than marijuana, and 3) more than one illicit drug other than marijuana, compared to “no use”. Results Report of neighborhood illicit drug selling was associated with lower friend disapproval of marijuana and cocaine; e.g., those who reported seeing neighborhood sales “almost every day” were less likely to report their friends strongly disapproved of marijuana (adjusted odds ratio [AOR] = 0.38, 95% CI: 0.29, 0.49) compared to those who reported never seeing neighborhood drug selling and reported no disapproval. Perception of neighborhood illicit drug selling was also associated with past-year drug use and past-month drug use; e.g., those who reported seeing neighborhood sales “almost every day” were more likely to report 30-day use of more than one illicit drug (AOR = 11.11, 95% CI: 7.47, 16.52) compared to those who reported never seeing neighborhood drug selling and reported no 30-day use of illicit drugs. Conclusions Perceived neighborhood drug selling was associated with lower peer disapproval and more illicit drug use among a population-based nationally representative sample of U.S. high school seniors. Policy interventions to reduce “open” (visible) neighborhood drug selling (e.g., problem-oriented policing and modifications to the physical environment such as installing and monitoring surveillance cameras) may

Antineoplastic Drugs

Sadée, Wolfgang; El Sayed, Yousry Mahmoud

The limited scope of therapeutic drug-level monitoring in cancer chemotherapy results from the often complex biochemical mechanisms that contribute to antineoplastic activity and obscure the relationships among drug serum levels and therapeutic benefits. Moreover, new agents for cancer chemotherapy are being introduced at a more rapid rate than for the treatment of other diseases, although the successful application of therapeutic drug-level monitoring may require several years of intensive study of the significance of serum drug levels. However, drug level monitoring can be of considerable value during phase I clinical trials of new antineoplastic agents in order to assess drug metabolism, bioavailability, and intersubject variability; these are important parameters in the interpretation of clinical studies, but have no immediate benefit to the patient. High performance liquid chromatography (HPLC) probably represents the most versatile and easily adaptable analytical technique for drug metabolite screening (1). HPLC may therefore now be the method of choice during phase I clinical trials of antineoplastic drugs. For example, within a single week we developed an HPLC assay—using a C18 reverse-phase column, UV detection, and direct serum injection after protein precipitation—for the new radiosensitizer, misonidazole (2).

Measured drug residue concentrations in the sewage are used to determine the load (total mass of the drug being used by the entire community. Knowledge of the size or population of the community then allows for the calculation of drug-use relative to population (typically drug-mass/day/1000 inhabitants which facilitates comparisons between differing communities or populations. Studies have been performed in many European countries, including Norway, as well as in the US and Australia. The approach has successfully estimated the use of cocaine, amphetamine, methamphetamine, MDMA, cannabis, nicotine and alcohol. The analysis of biomarkers of drug use in sewage has great potential to support and complement existing techniques for estimating levels of drug use, and as such has been identified as a promising development by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA; www.emcdda.europa.eu/wastewater-analysis. The approach is not without its challenges, and ongoing collaboration across Europe aims at agreeing upon best-practice and harmonising the methods being used. In Norway development is being performed through the NFR RUSMIDDEL funded DrugMon (www.niva.no/drugmon project that has led to the development of many new techniques, significantly improved our understanding of the uncertainties associated with the approach and allowed the coordination of Europe wide collaboration which has included all important intercalibration exercises. Application of the technique can provide evidence-based and real-time estimates of collective drug use with the resulting data used to improve the much needed estimates of drug use and dependency.

To examine the effects of a permissive attitude towards regular and occasional drug use, life satisfaction, self-esteem, depression, and other psychosocial variables in the drug use of psychoactive drug users. Psychosocial factors that might affect a permissive attitude towards regular / occasional drug use and life satisfaction were further explored. We analysed data of a sample of psychoactive drug users from a longitudinal survey of psychoactive drug abusers in Hong Kong who were interviewed at 6 time points at 6-month intervals between January 2009 and December 2011. Data of the second to the sixth time points were stacked into an individual time point structure. Random-effects probit regression analysis was performed to estimate the relative contribution of the independent variables to the binary dependent variable of drug use in the last 30 days. A permissive attitude towards drug use, life satisfaction, and depression at the concurrent time point, and self-esteem at the previous time point had direct effects on drug use in the last 30 days. Interestingly, permissiveness to occasional drug use was a stronger predictor of drug use than permissiveness to regular drug use. These 2 permissive attitude variables were affected by the belief that doing extreme things shows the vitality of young people (at concurrent time point), life satisfaction (at concurrent time point), and self-esteem (at concurrent and previous time points). Life satisfaction was affected by sense of uncertainty about the future (at concurrent time point), self-esteem (at concurrent time point), depression (at both concurrent and previous time points), and being stricken by stressful events (at previous time point). A number of psychosocial factors could affect the continuation or discontinuation of drug use, as well as the permissive attitude towards regular and occasional drug use, and life satisfaction.

Full Text Available Better the drugs you know than the drugs you do not know. Drug repurposing is a promising, fast, and cost effective method that can overcome traditional de novo drug discovery and development challenges of targeting neuropsychiatric and other disorders. Drug discovery and development targeting neuropsychiatric disorders are complicated because of the limitations in understanding pathophysiological phenomena. In addition, traditional de novo drug discovery and development are risky, expensive, and time-consuming processes. One alternative approach, drug repurposing, has emerged taking advantage of off-target effects of the existing drugs. In order to identify new opportunities for the existing drugs, it is essential for us to understand the mechanisms of action of drugs, both biologically and pharmacologically. By doing this, drug repurposing would be a more effective method to develop drugs against neuropsychiatric and other disorders. Here, we review the difficulties in drug discovery and development in neuropsychiatric disorders and the extent and perspectives of drug repurposing.

Guerreiro, Diogo Frasquilho; Carmo, Ana Lisa; da Silva, Joaquim Alves; Navarro, Rita; Góis, Carlos

2011-01-01

Club drugs are the following substances: Methylenedioxymethamphetamine (MDMA); Methamphetamine; Lysergic Acid Diethylamide (LSD); Ketamine; Gamma-hydroxybutyrate (GHB) and Flunitrazepam. These substances are mainly used by adolescents and young adults, mostly in recreational settings like dance clubs and rave parties. These drugs have diverse psychotropic effects, are associated with several degrees of toxicity, dependence and long term adverse effects. Some have been used for several decades, while others are relatively recent substances of abuse. They have distinct pharmacodynamic and pharmacokinetic properties, are not easy to detect and, many times, the use of club drugs is under diagnosed. Although the use of these drugs is increasingly common, few health professionals feel comfortable with the diagnosis and treatment. The authors performed a systematic literature review, with the goal of synthesising the existing knowledge about club drugs, namely epidemiology, mechanism of action, detection, adverse reactions and treatment. The purpose of this article is creating in Portuguese language a knowledge data base on club drugs, that health professionals of various specialties can use as a reference when dealing with individual with this kind of drug abuse.

Human Drug Discrimination: Elucidating the Neuropharmacology of Commonly Abused Illicit Drugs.

Drug-discrimination procedures empirically evaluate the control that internal drug states have over behavior. They provide a highly selective method to investigate the neuropharmacological underpinnings of the interoceptive effects of drugs in vivo. As a result, drug discrimination has been one of the most widely used assays in the field of behavioral pharmacology. Drug-discrimination procedures have been adapted for use with humans and are conceptually similar to preclinical drug-discrimination techniques in that a behavior is differentially reinforced contingent on the presence or absence of a specific interoceptive drug stimulus. This chapter provides a basic overview of human drug-discrimination procedures and reviews the extant literature concerning the use of these procedures to elucidate the underlying neuropharmacological mechanisms of commonly abused illicit drugs (i.e., stimulants, opioids, and cannabis) in humans. This chapter is not intended to review every available study that used drug-discrimination procedures in humans. Instead, when possible, exemplary studies that used a stimulant, opioid, or Δ 9 -tetrahydrocannabinol (the primary psychoactive constituent of cannabis) to assess the discriminative-stimulus effects of drugs in humans are reviewed for illustrative purposes. We conclude by commenting on the current state and future of human drug-discrimination research.

Allosteric cross-talk in chromatin can mediate drug-drug synergy

2017-03-01

Exploitation of drug-drug synergism and allostery could yield superior therapies by capitalizing on the immensely diverse, but highly specific, potential associated with the biological macromolecular landscape. Here we describe a drug-drug synergy mediated by allosteric cross-talk in chromatin, whereby the binding of one drug alters the activity of the second. We found two unrelated drugs, RAPTA-T and auranofin, that yield a synergistic activity in killing cancer cells, which coincides with a substantially greater number of chromatin adducts formed by one of the compounds when adducts from the other agent are also present. We show that this occurs through an allosteric mechanism within the nucleosome, whereby defined histone adducts of one drug promote reaction of the other drug at a distant, specific histone site. This opens up possibilities for epigenetic targeting and suggests that allosteric modulation in nucleosomes may have biological relevance and potential for therapeutic interventions.

Food-drug interactions

Interactions between food and drugs may inadvertently reduce or increase the drug effect. The majority of clinically relevant food-drug interactions are caused by food-induced changes in the bioavailability of the drug. Since the bioavailability and clinical effect of most drugs are correlated......, the bioavailability is an important pharmacokinetic effect parameter. However, in order to evaluate the clinical relevance of a food-drug interaction, the impact of food intake on the clinical effect of the drug has to be quantified as well. As a result of quality review in healthcare systems, healthcare providers...... are increasingly required to develop methods for identifying and preventing adverse food-drug interactions. In this review of original literature, we have tried to provide both pharmacokinetic and clinical effect parameters of clinically relevant food-drug interactions.

DRUG MANAGEMENT REVIEWS IN DISTRICT DRUG MANAGEMENT UNIT AND GENERAL HOSPITAL

Directory of Open Access Journals (Sweden)

Max Joseph Herman

2009-12-01

Full Text Available Drug is one of the essential elements in healthcare that should be effectively and efficiently managed. Following thedecentralization in 2001 in Indonesia, drug management has changed in district drug management units and also in District General Hospitals. Certainly this condition influences the sustainability of drug access in primary health care such as in Community Health Center and District General Hospital, especially in drug financing policy. A cross sectional descriptive study to obtain information on drug management in public healthcare in district had been carried out between July and December 2006 in 10 District Public Drug Management Units from 10 district health offices and 9 district general hospitals as samples. Data were collected by interviewing heads of Drug Section in District Health Offices and heads of Hospital Pharmacies using structured questionnaires and observing drug storage in District Drug Management Units, Community Health Centers, and Hospital Pharmacies. Results of the study show that drug planning in District Health Offices and General Hospitals did not meet the basic real need in some districts nor District Hospitals. The minimum health service standards had no been achieved yet. Furthermore, drug procurement, storage and recording as well as reporting was not good enough either, such as shown by the existence of expired drugs. Lead time for drug delivery to community health centers in some districts was longer than the average of lead time in the past 3 years.

Drugs as instruments: a new framework for non-addictive psychoactive drug use.

Science.gov (United States)

Müller, Christian P; Schumann, Gunter

2011-12-01

Most people who are regular consumers of psychoactive drugs are not drug addicts, nor will they ever become addicts. In neurobiological theories, non-addictive drug consumption is acknowledged only as a "necessary" prerequisite for addiction, but not as a stable and widespread behavior in its own right. This target article proposes a new neurobiological framework theory for non-addictive psychoactive drug consumption, introducing the concept of "drug instrumentalization." Psychoactive drugs are consumed for their effects on mental states. Humans are able to learn that mental states can be changed on purpose by drugs, in order to facilitate other, non-drug-related behaviors. We discuss specific "instrumentalization goals" and outline neurobiological mechanisms of how major classes of psychoactive drugs change mental states and serve non-drug-related behaviors. We argue that drug instrumentalization behavior may provide a functional adaptation to modern environments based on a historical selection for learning mechanisms that allow the dynamic modification of consummatory behavior. It is assumed that in order to effectively instrumentalize psychoactive drugs, the establishment of and retrieval from a drug memory is required. Here, we propose a new classification of different drug memory subtypes and discuss how they interact during drug instrumentalization learning and retrieval. Understanding the everyday utility and the learning mechanisms of non-addictive psychotropic drug use may help to prevent abuse and the transition to drug addiction in the future.

Drug interactions with oral sulphonylurea hypoglycaemic drugs.

Science.gov (United States)

Hansen, J M; Christensen, L K

1977-01-01

The effect of the oral sulphonylurea hypoglycaemic drugs may be influenced by a large number of other drugs. Some of these combinations (e.g. phenylbutazone, sulphaphenazole) may result in cases of severe hypoglycaemic collapse. Tolbutamide and chlorpropamide should never be given to a patient without a prior careful check of which medicaments are already being given. Similarly, no drug should be given to a diabetic treated with tolbutamide and chlorpropamide without consideration of the possibility of interaction phenomena.

Optimization of Drug Delivery by Drug-Eluting Stents.

Directory of Open Access Journals (Sweden)

Franz Bozsak

Full Text Available Drug-eluting stents (DES, which release anti-proliferative drugs into the arterial wall in a controlled manner, have drastically reduced the rate of in-stent restenosis and revolutionized the treatment of atherosclerosis. However, late stent thrombosis remains a safety concern in DES, mainly due to delayed healing of the endothelial wound inflicted during DES implantation. We present a framework to optimize DES design such that restenosis is inhibited without affecting the endothelial healing process. To this end, we have developed a computational model of fluid flow and drug transport in stented arteries and have used this model to establish a metric for quantifying DES performance. The model takes into account the multi-layered structure of the arterial wall and incorporates a reversible binding model to describe drug interaction with the cells of the arterial wall. The model is coupled to a novel optimization algorithm that allows identification of optimal DES designs. We show that optimizing the period of drug release from DES and the initial drug concentration within the coating has a drastic effect on DES performance. Paclitaxel-eluting stents perform optimally by releasing their drug either very rapidly (within a few hours or very slowly (over periods of several months up to one year at concentrations considerably lower than current DES. In contrast, sirolimus-eluting stents perform optimally only when drug release is slow. The results offer explanations for recent trends in the development of DES and demonstrate the potential for large improvements in DES design relative to the current state of commercial devices.

Less targeted and limited solubility of hydrophobic-based drug are one of the serious obstacles in drug delivery system. Thus, new strategies to enhance the solubility of hydrophobic drug and controlled release behaviors would be developed. Herein, curcumin, a model of hydrophobic drug, has been loaded into PEGylated magnetic liposomes as a drug carrier platform for drug controlled release system. Inductive magnetic heating (hyperthermia)-stimulated drug release, in vitro cellular cytotoxicity assay of curcumin-loaded PEGylated magnetic liposomes and cellular internalization-induced by magnetic guidance would be investigated. The resultant of drug carriers could disperse homogeneously in aqueous solution, showing a superparamagnetic characteristic and could inductive magnetic heating with external high-frequency magnetic field (HFMF). In vitro curcumin release studies confirmed that the drug carriers exhibited no significant release at 37 °C, whereas exhibited rapid releasing at 45 °C. However, it would display enormous (three times higher) curcumin releasing under the HFMF exposure, compared with that without HFMF exposure at 45 °C. In vitro cytotoxicity test shows that curcumin-loaded PEGylated magnetic liposomes could efficiently kill MCF-7 cells in parallel with increasing curcumin concentration. Fluorescence microscopy observed that these drug carriers could internalize efficiently into the cellular compartment of MCF-7 cells. Thus, it would be anticipated that the novel hydrophobic drug-loaded PEGylated magnetic liposomes in combination with inductive magnetic heating are promising to apply in the combination of chemotherapy and thermotherapy for cancer therapy.

Hidden wholesale: The drug diffusing capacity of online drug cryptomarkets.

Science.gov (United States)

Aldridge, Judith; Décary-Hétu, David

2016-09-01

In spite of globalizing processes 'offline' retail drug markets remain localized and - in recent decades - typically 'closed', in which dealers sell primarily to known customers. We characterize drug cryptomarkets as 'anonymous open' marketplaces that allow the diffusion of drugs across locales. Where cryptomarket customers make stock-sourcing purchases for offline distribution, the cryptomarket may indirectly serve drug users who are not themselves cryptomarket customers, thereby increasing the drug diffusing capacity of these marketplaces. Our research aimed to identify wholesale activity on the first major cryptomarket, Silk Road 1. Data were collected 13-15 September 2013. A bespoke web crawler downloaded content from the first major drug cryptomarket, Silk Road 1. This generated data on 1031 vendors and 10,927 drug listings. We estimated monthly revenues to ascertain the relative importance of wholesale priced listings. Wholesale-level revenue generation (sales for listings priced over USD $1000.00) accounted for about a quarter of the revenue generation on SR1 overall. Ecstasy-type drugs dominated wholesale activity on this marketplace, but we also identified substantial wholesale transactions for benzodiazepines and prescription stimulants. Less important, but still generating wholesale revenue, were cocaine, methamphetamine and heroin. Although vendors on the marketplace were located in 41 countries, wholesale activity was confined to only a quarter of these, with China, the Netherlands, Canada and Belgium prominent. The cryptomarket may function in part as a virtual broker, linking wholesalers with offline retail-level distributors. For drugs like ecstasy, these marketplaces may link vendors in producer countries directly with retail level suppliers. Wholesale activity on cryptomarkets may serve to increase the diffusion of new drugs - and wider range of drugs - in offline drug markets, thereby indirectly serving drug users who are not cryptomarket

DrugSig: A resource for computational drug repositioning utilizing gene expression signatures.

Directory of Open Access Journals (Sweden)

Hongyu Wu

Full Text Available Computational drug repositioning has been proved as an effective approach to develop new drug uses. However, currently existing strategies strongly rely on drug response gene signatures which scattered in separated or individual experimental data, and resulted in low efficient outputs. So, a fully drug response gene signatures database will be very helpful to these methods. We collected drug response microarray data and annotated related drug and targets information from public databases and scientific literature. By selecting top 500 up-regulated and down-regulated genes as drug signatures, we manually established the DrugSig database. Currently DrugSig contains more than 1300 drugs, 7000 microarray and 800 targets. Moreover, we developed the signature based and target based functions to aid drug repositioning. The constructed database can serve as a resource to quicken computational drug repositioning. Database URL: http://biotechlab.fudan.edu.cn/database/drugsig/.

High-Throughput Cytochrome P450 Cocktail Inhibition Assay for Assessing Drug-Drug and Drug-Botanical Interactions.

Science.gov (United States)

Li, Guannan; Huang, Ke; Nikolic, Dejan; van Breemen, Richard B

2015-11-01

Detection of drug-drug interactions is essential during the early stages of drug discovery and development, and the understanding of drug-botanical interactions is important for the safe use of botanical dietary supplements. Among the different forms of drug interactions that are known, inhibition of cytochrome P450 (P450) enzymes is the most common cause of drug-drug or drug-botanical interactions. Therefore, a rapid and comprehensive mass spectrometry-based in vitro high-throughput P450 cocktail inhibition assay was developed that uses 10 substrates simultaneously against nine CYP isoforms. Including probe substrates for CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2E1, and two probes targeting different binding sites of CYP3A4/5, this cocktail simultaneously assesses at least as many P450 enzymes as previous assays while remaining among the fastest due to short incubation times and rapid analysis using ultrahigh pressure liquid chromatography-tandem mass spectrometry. The method was validated using known inhibitors of each P450 enzyme and then shown to be useful not only for single-compound testing but also for the evaluation of potential drug-botanical interactions using the botanical dietary supplement licorice (Glycyrrhiza glabra) as an example.

Altered drug metabolism during pregnancy: hormonal regulation of drug-metabolizing enzymes.

Science.gov (United States)

Jeong, Hyunyoung

2010-06-01

Medication use during pregnancy is prevalent, but pharmacokinetic information of most drugs used during pregnancy is lacking in spite of known effects of pregnancy on drug disposition. Accurate pharmacokinetic information is essential for optimal drug therapy in mother and fetus. Thus, understanding how pregnancy influences drug disposition is important for better prediction of pharmacokinetic changes of drugs in pregnant women. Pregnancy is known to affect hepatic drug metabolism, but the underlying mechanisms remain unknown. Physiological changes accompanying pregnancy are probably responsible for the reported alteration in drug metabolism during pregnancy. These include elevated concentrations of various hormones such as estrogen, progesterone, placental growth hormones and prolactin. This review covers how these hormones influence expression of drug-metabolizing enzymes (DMEs), thus potentially responsible for altered drug metabolism during pregnancy. The reader will gain a greater understanding of the altered drug metabolism in pregnant women and the regulatory effects of pregnancy hormones on expression of DMEs. In-depth studies in hormonal regulatory mechanisms as well as confirmatory studies in pregnant women are warranted for systematic understanding and prediction of the changes in hepatic drug metabolism during pregnancy.

Illicit Drug Use, Illicit Drug Use Disorders, and Drug Overdose Deaths in Metropolitan and Nonmetropolitan Areas - United States.

Mack, Karin A; Jones, Christopher M; Ballesteros, Michael F

2017-10-20

Drug overdoses are a leading cause of injury death in the United States, resulting in approximately 52,000 deaths in 2015. Understanding differences in illicit drug use, illicit drug use disorders, and overall drug overdose deaths in metropolitan and nonmetropolitan areas is important for informing public health programs, interventions, and policies. Illicit drug use and drug use disorders during 2003-2014, and drug overdose deaths during 1999-2015. The National Survey of Drug Use and Health (NSDUH) collects information through face-to-face household interviews about the use of illicit drugs, alcohol, and tobacco among the U.S. noninstitutionalized civilian population aged ≥12 years. Respondents include residents of households and noninstitutional group quarters (e.g., shelters, rooming houses, dormitories, migratory workers' camps, and halfway houses) and civilians living on military bases. NSDUH variables include sex, age, race/ethnicity, residence (metropolitan/nonmetropolitan), annual household income, self-reported drug use, and drug use disorders. National Vital Statistics System Mortality (NVSS-M) data for U.S. residents include information from death certificates filed in the 50 states and the District of Columbia. Cases were selected with an underlying cause of death based on the ICD-10 codes for drug overdoses (X40-X44, X60-X64, X85, and Y10-Y14). NVSS-M variables include decedent characteristics (sex, age, and race/ethnicity) and information on intent (unintentional, suicide, homicide, or undetermined), location of death (medical facility, in a home, or other [including nursing homes, hospices, unknown, and other locations]) and county of residence (metropolitan/nonmetropolitan). Metropolitan/nonmetropolitan status is assigned independently in each data system. NSDUH uses a three-category system: Core Based Statistical Area (CBSA) of ≥1 million persons; CBSA of illicit drugs, the prevalence was highest for the large metropolitan areas compared with

Drug resistance in leishmaniasis: current drug-delivery systems and future perspectives.

Science.gov (United States)

Yasinzai, Masoom; Khan, Momin; Nadhman, Akhtar; Shahnaz, Gul

2013-10-01

Leishmaniasis is a complex of diseases with numerous clinical manifestations for instance harshness from skin lesions to severe disfigurement and chronic systemic infection in the liver and spleen. So far, the most classical leishmaniasis therapy, despite its documented toxicities, remains pentavalent antimonial compounds. The arvailable therapeutic modalities for leishmaniasis are overwhelmed with resistance to leishmaniasis therapy. Mechanisms of classical drug resistance are often related with the lower drug uptake, increased efflux, the faster drug metabolism, drug target modifications and over-expression of drug transporters. The high prevalence of leishmaniasis and the appearance of resistance to classical drugs reveal the demand to develop and explore novel, less toxic, low cost and more promising therapeutic modalities. The review describes the mechanisms of classical drug resistance and potential drug targets in Leishmania infection. Moreover, current drug-delivery systems and future perspectives towards Leishmaniasis treatment are also covered.

Drug Use, the Drug Environment, and Child Physical Abuse and Neglect.

Science.gov (United States)

Freisthler, Bridget; Wolf, Jennifer Price; Wiegmann, Wendy; Kepple, Nancy J

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.

The importance of illicit drug price data and making appropriate adjustments for purity has been repeatedly highlighted for understanding illicit drug markets. The European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) has been collecting retail price data for a number of drug types alongside drug-specific purity information for over 15 years. While these data are useful for a number of monitoring and analytical purposes, they are not without their limitations and there are circumstances where additional adjustment needs to be considered. This paper reviews some conceptual issues and measurement challenges relevant to the interpretation of price data. It also highlights the issues with between-country comparisons of drug prices and introduces the concept of affordability of drugs, going beyond purity-adjustment to account for varying national economies. Based on a 2015 European data set of price and purity data across the heroin and cocaine retail markets, the paper demonstrates a new model for drug market comparative analysis; calculation of drug affordability is achieved by applying to purity-adjusted prices 2015 Price Level Indices (PLI, Eurostat). Available data allowed retail heroin and cocaine market comparison for 27 European countries. The lowest and highest unadjusted prices per gram were observed for heroin: in Estonia, Belgium, Greece and Bulgaria (lowest) and Finland, Ireland, Sweden and Latvia (highest); for cocaine: the Netherlands, Belgium and the United Kingdom (lowest) and Turkey, Finland, Estonia and Romania (highest). The affordability per gram of heroin and cocaine when taking into account adjustment for both purity and economy demonstrates different patterns. It is argued that purity-adjusted price alone provides an incomplete comparison of retail price across countries. The proposed new method takes account of the differing economic conditions within European countries, thus providing a more sophisticated tool for cross

Full Text Available Antipsychotic drugs are medications commonly for schizophrenia (SCZ treatment, which include two groups: typical and atypical. SCZ patients have multiple comorbidities, and the coadministration of drugs is quite common. This may result in adverse drug-drug interactions, which are events that occur when the effect of a drug is altered by the coadministration of another drug. Therefore, it is important to provide a comprehensive view of these interactions for further coadministration improvement. Here, we extracted SCZ drugs and their adverse drug interactions from the DrugBank and compiled a SCZ-specific adverse drug interaction network. This network included 28 SCZ drugs, 241 non-SCZs, and 991 interactions. By integrating the Anatomical Therapeutic Chemical (ATC classification with the network analysis, we characterized those interactions. Our results indicated that SCZ drugs tended to have more adverse drug interactions than other drugs. Furthermore, SCZ typical drugs had significant interactions with drugs of the “alimentary tract and metabolism” category while SCZ atypical drugs had significant interactions with drugs of the categories “nervous system” and “antiinfectives for systemic uses.” This study is the first to characterize the adverse drug interactions in the course of SCZ treatment and might provide useful information for the future SCZ treatment.

Confusing the drug facts on one nonprescription drug label with those on another: The Drug Facts Label as a text schema

Full Text Available The Drug Facts Label is designed to guide consumers in comparing nonprescription drugs. Undergraduates studied and recalled drug facts for three analgesic or non-analgesic labels using Drug Facts Label headings as retrieval cues. They then studied and recalled drug facts from an aspirin label. Aspirin recall was greater when the prior labels were analgesics, but prior-label intrusion errors were also greater. These two effects were associated with the number of prior drug labels on which facilitating and interfering drug facts appeared. Using the Drug Facts Label schema to read drug labels can both enhance and degrade the recall of nonprescription drug facts.

Currently, most guidelines on drug-drug interaction (DDI) neither consider the potential effect of genetic polymorphism in the strength of the interaction nor do they account for the complex interaction caused by the combination of DDI and drug-gene interaction (DGI) where there are multiple biotransformation pathways, which is referred to as drug-drug-gene interaction (DDGI). In this systematic review, we report the impact of pharmacogenetics on DDI and DDGI in which three major drug-metabolizing enzymes - CYP2C9, CYP2C19 and CYP2D6 - are central. We observed that several DDI and DDGI are highly gene-dependent, leading to a different magnitude of interaction. Precision drug therapy should take pharmacogenetics into account when drug interactions in clinical practice are expected.

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.

Chytil, Petr; Koziolová, Eva; Etrych, Tomáš; Ulbrich, Karel

2018-01-01

Over the past few decades, numerous polymer drug carrier systems are designed and synthesized, and their properties are evaluated. Many of these systems are based on water-soluble polymer carriers of low-molecular-weight drugs and compounds, e.g., cytostatic agents, anti-inflammatory drugs, or multidrug resistance inhibitors, all covalently bound to a carrier by a biodegradable spacer that enables controlled release of the active molecule to achieve the desired pharmacological effect. Among others, the synthetic polymer carriers based on N-(2-hydroxypropyl) methacrylamide (HPMA) copolymers are some of the most promising carriers for this purpose. This review focuses on advances in the development of HPMA copolymer carriers and their conjugates with anticancer drugs, with triggered drug activation in tumor tissue and especially in tumor cells. Specifically, this review highlights the improvements in polymer drug carrier design with respect to the structure of a spacer to influence controlled drug release and activation, and its impact on the drug pharmacokinetics, enhanced tumor uptake, cellular trafficking, and in vivo antitumor activity. © 2017 WILEY-VCH Verlag GmbH & Co.

Drug Retention Times

Energy Technology Data Exchange (ETDEWEB)

None, None

2007-05-01

The purpose of this monograph is to provide information on drug retention times in the human body. The information provided is based on plausible illegal drug use activities that might be engaged in by a recreational drug user. Based on anecdotal evidence, most people “party” during extended time away from the work environment. Therefore, the following scenarios were envisioned: (1) a person uses an illicit drug at a party on Saturday night (infrequent user); (2) a person uses a drug one time on Friday night and once again on Saturday night (infrequent user); and (3) a person uses a drug on Friday night, uses a drug twice on Saturday night, and once again on Sunday (frequent user).

A total of 103 drugs (including 14 combination drugs) were approved by the U.S. Food and Drug Administration from 2013 to 2016. Pharmacokinetic-based drug interaction profiles were analyzed using the University of Washington Drug Interaction Database and the clinical relevance of these observations was characterized based on information from New Drug Application reviews. CYP3A was identified as a major contributor to clinical drug-drug interactions (DDIs), involved in approximately 2/3 of all interactions. Transporters (alone or with enzymes) were found to participate in about half of all interactions, although most of these were weak-to-moderate interactions. When considered as victims, eight new molecular entities (NMEs; cobimetinib, ibrutnib, isavuconazole, ivabradine, naloxegol, paritaprevir, simeprevir, and venetoclax) were identified as sensitive substrates of CYP3A, two NMEs (pirfenidone and tasimelteon) were sensitive substrates of CYP1A2, one NME (dasabuvir) was a sensitive substrate of CYP2C8, one NME (eliglustat) was a sensitive substrate of CYP2D6, and one NME (grazoprevir) was a sensitive substrate of OATP1B1/3 (with changes in exposure greater than 5-fold when co-administered with a strong inhibitor). Interestingly, approximately 75% of identified CYP3A substrates were also substrates of P-gp. As perpetrators, most clinical DDIs involved weak-to-moderate inhibition or induction, with only two drugs (Viekira Pak and idelalisib) showing strong inhibition of CYP3A, and one NME (lumacaftor) considered as a strong CYP3A inducer. Among drugs with large changes in exposure (≥ 5-fold), whether as victim or perpetrator, the most represented therapeutic classes were antivirals and oncology drugs, suggesting a significant risk of clinical DDIs in these patient populations.

Full Text Available Abstract Aim This study aimed to examine drug use, drug treatment history and risk behaviour among a sample of Iranian drug users seeking treatment through a general practice clinic in Iran. Methods Review of medical records and an intake questionnaire at a large general practice in Marvdasht, Iran, with a special interest in drug dependence treatment. Records from a random sample of injecting drug users (IDU, non-injecting drug users (DU and non-drug using patients were examined. Results 292 records were reviewed (34% IDU, 31% DU and 35% non-drug users. Eighty-three percent were males; all females were non-drug users. The mean age of the sample was 30 years. Of the IDU sample, 67% reported sharing a needle or syringe, 19% of these had done so in prison. Of those who had ever used drugs, being 'tired' of drug use was the most common reason for seeking help (34%. Mean age of first drug use was 20 years. The first drugs most commonly used were opium (72%, heroin (13% and hashish/ other cannabinoids (13%. Three quarters reported having previously attempted to cease their drug use. IDU were more likely than DU to report having ever been imprisoned (41% vs 7% and 41% to have used drugs in prison. Conclusion This study has shown that there is a need for general practice clinics in Iran to treat drug users including those who inject and that a substantial proportion of those who inject have shared needles and syringes, placing them at risk of BBVI such as HIV and hepatitis C. The expansion of services for drug users in Iran such as needle and syringe programs and pharmacotherapies are likely to be effective in reducing the harms associated with opium use and heroin injection.

Violence is amongst the primary concerns of communities around the world and research has demonstrated links between violence and the illicit drug trade, particularly in urban settings. Given the growing emphasis on evidence-based policy-making, and the ongoing severe drug market violence in Mexico and other settings, we conducted a systematic review to examine the impacts of drug law enforcement on drug market violence. We conducted a systematic review using Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines. Specifically, we undertook a search of English language electronic databases (Academic Search Complete, PubMed, PsycINFO, EMBASE, Web of Science, Sociological Abstracts, Social Service Abstracts, PAIS International and Lexis-Nexis), the Internet (Google, Google Scholar), and article reference lists, from database inception to January 24, 2011. Overall, 15 studies were identified that evaluated the impact of drug law enforcement on drug market violence, including 11 (73%) longitudinal analyses using linear regression, 2 (13%) mathematical drug market models, and 2 (13%) qualitative studies. Fourteen (93%) studies reported an adverse impact of drug law enforcement on levels of violence. Ten of the 11 (91%) studies employing longitudinal qualitative analyses found a significant association between drug law enforcement and drug market violence. Our findings suggest that increasing drug law enforcement is unlikely to reduce drug market violence. Instead, the existing evidence base suggests that gun violence and high homicide rates may be an inevitable consequence of drug prohibition and that disrupting drug markets can paradoxically increase violence. In this context, and since drug prohibition has not meaningfully reduced drug supply, alternative regulatory models will be required if drug supply and drug market violence are to be meaningfully reduced.

The number of drugs that are found to be photochemically unstable or able to induce phototoxic side-effects is steadily increasing. It can be difficult, however, to obtain relevant information on the photoreactivity of drugs or drug products from the commonly used handbooks. This is because of lack of standard methods of evaluation or a requirement for official specifications for a given product. The author points to the main problems connected with interactions between drugs and light in vitro and in vivo. The most obvious result of exposure to light is reduced potency of the drug because of photodecomposition. Adverse effects due to the formation of photodegradation products during storage and use have also been reported. The drug substance can further cause light-induced side-effects after administration to the patient, e.g. phototoxicity and photoallergy. More data on photoreactivity are needed in order to minimize the side-effects of frequently used drugs. The article includes a list of potential photosensitizing drug substances on the Norwegian market.

Nanotechnology has attracted great attention all over the world in recent several years and has led to the establishment of the novel technical field of "nanomedicine" through collaboration with advanced medical technology. Particularly, site-specific drug targeting using particle drug carrier systems has made substantial progress and been actively developed. This review explains the essential factors (size and chemical character) of drug carriers to allow long circulation in the bloodstream avoiding the reticuloendothelial system, and shows the present status and future perspective of several types of nano-carrier systems (water-soluble polymer, liposome and polymeric micelle). We also introduce the novel concept of multi-targeting system (combination of two or more targeting methodologies) for ideal drug therapies.

Full Text Available Objective: To determine the prevalence of potential clinically relevant drug- drug interactions in adult oncological inpatients, as well as to describe the most frequent interactions. A standard database was used. Method: An observational, transversal, and descriptive study including patients admitted to the Oncology Service of a reference hospital. All prescriptions were collected twice a week during a month. They were analysed using Lexicomp® database, recording all interactions classified with a level of risk: C, D or X. Results: A total of 1 850 drug-drug interactions were detected in 218 treatments. The prevalence of treatments with at least one clinically relevant interaction was 95%, being 94.5% for those at level C and 26.1% for levels D and X. The drugs most commonly involved in the interactions detected were opioid analgesics, antipsychotics (butyrophenones, benzodiazepines, pyrazolones, glucocorticoids and heparins, whereas interactions with antineoplastics were minimal, highlighting those related to paclitaxel and between metamizole and various antineoplastics. Conclusions: The prevalence of clinically relevant drug-drug interactions rate was very high, highlighting the high risk percentage of them related to level of risk X. Due to the frequency of onset and potential severity, highlighted the concomitant use of central nervous system depressants drugs with risk of respiratory depression, the risk of onset of anticholinergic symptoms when combining morphine or haloperidol with butylscopolamine, ipratropium bromide or dexchlorpheniramine and the multiple interactions involving metamizole.

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.

Drug-Drug Multicomponent Solid Forms: Cocrystal, Coamorphous and Eutectic of Three Poorly Soluble Antihypertensive Drugs Using Mechanochemical Approach.

Haneef, Jamshed; Chadha, Renu

2017-08-01

The present study deals with the application of mechanochemical approach for the preparation of drug-drug multicomponent solid forms of three poorly soluble antihypertensive drugs (telmisartan, irbesartan and hydrochlorothiazide) using atenolol as a coformer. The resultant solid forms comprise of cocrystal (telmisartan-atenolol), coamorphous (irbesartan-atenolol) and eutectic (hydrochlorothiazide-atenolol). The study emphasizes that solid-state transformation of drug molecules into new forms is a result of the change in structural patterns, diminishing of dimers and creating new facile hydrogen bonding network based on structural resemblance. The propensity for heteromeric or homomeric interaction between two different drugs resulted into diverse solid forms (cocrystal/coamorphous/eutectics) and become one of the interesting aspects of this research work. Evaluation of these solid forms revealed an increase in solubility and dissolution leading to better antihypertensive activity in deoxycorticosterone acetate (DOCA) salt-induced animal model. Thus, development of these drug-drug multicomponent solid forms is a promising and viable approach to addressing the issue of poor solubility and could be of considerable interest in dual drug therapy for the treatment of hypertension.

Joyce, Helena; McCann, Andrew; Clynes, Martin; Larkin, Annemarie

2015-05-01

Chemotherapy involving the use of anticancer drugs remains an important strategy in the overall management of patients with metastatic cancer. Acquisition of multidrug resistance remains a major impediment to successful chemotherapy. Drug transporters in cell membranes and intracellular drug metabolizing enzymes contribute to the resistance phenotype and determine the pharmacokinetics of anticancer drugs in the body. ATP-binding cassette (ABC) transporters mediate the transport of endogenous metabolites and xenobiotics including cytotoxic drugs out of cells. Solute carrier (SLC) transporters mediate the influx of cytotoxic drugs into cells. This review focuses on the substrate interaction of these transporters, on their biology and what role they play together with drug metabolizing enzymes in eliminating therapeutic drugs from cells. The majority of anticancer drugs are substrates for the ABC transporter and SLC transporter families. Together, these proteins have the ability to control the influx and the efflux of structurally unrelated chemotherapeutic drugs, thereby modulating the intracellular drug concentration. These interactions have important clinical implications for chemotherapy because ultimately they determine therapeutic efficacy, disease progression/relapse and the success or failure of patient treatment.

Gao Lei; Zhang Dianrui; Chen Minghui

2008-01-01

Formulation of poorly soluble drugs is a general intractable problem in pharmaceutical field, especially those compounds poorly soluble in both aqueous and organic media. It is difficult to resolve this problem using conventional formulation approaches, so many drugs are abandoned early in discovery. Nanocrystals, a new carrier-free colloidal drug delivery system with a particle size ranging from 100 to 1000 nm, is thought as a viable drug delivery strategy to develop the poorly soluble drugs, because of their simplicity in preparation and general applicability. In this article, the product techniques of the nanocrystals were reviewed and compared, the special features of drug nanocrystals were discussed. The researches on the application of the drug nanocrystals to various administration routes were described in detail. In addition, as introduced later, the nanocrystals could be easily scaled up, which was the prerequisite to the development of a delivery system as a market product

Full Text Available Although essentially not all therapies need drug intervention, drugs is still an important components in health sector, either in preventive, curative, rehabilitative or promotion efforts. Hence the access to drugs is a main problem, either in international or national scale even to the smallest unit. The problem on access to drugs is very complicated and cannot be separated especially from pharmacy management problems; moreover in general from the overall lack of policy development and effective of health policy, and also the implementation process. With the policy development and effective health policy, rational drug uses, sufficient health service budget so a country can overcome the health problems. Besides infrastructures, regulations, distribution and cultural influences; the main obstacles for drug access is drugs affordability if the price of drugs is an important part and determined by many factors, especially the drug status whether is still patent orgenerics that significantly decrease cost of health cares and enhance the drugs affordability. The determination of essential drug prices in developing countries should based on equity principal so that poor people pay cheaper and could afford the essential drugs. WHO predicts two third of world population can not afford the essential drugs in which in developing countries, some are because of in efficient budget allocation in consequence of drug distribution management, including incorrect selection and allocation and also irrational uses. In part these could be overcome by enhancing performances on the allocation pharmacy needs, including the management of information system, inventory management, stock management and the distribution. Key words: access, drugs, essential drugs, generic drugs

Drug-drug interactions of antifungal agents and implications for patient care.

Gubbins, Paul O; Amsden, Jarrett R

2005-10-01

Drug interactions in the gastrointestinal tract, liver and kidneys result from alterations in pH, ionic complexation, and interference with membrane transport proteins and enzymatic processes involved in intestinal absorption, enteric and hepatic metabolism, renal filtration and excretion. Azole antifungals can be involved in drug interactions at all the sites, by one or more of the above mechanisms. Consequently, azoles interact with a vast array of compounds. Drug-drug interactions associated with amphotericin B formulations are predictable and result from the renal toxicity and electrolyte disturbances associated with these compounds. The echinocandins are unknown cytochrome P450 substrates and to date are relatively devoid of significant drug-drug interactions. This article reviews drug interactions involving antifungal agents that affect other agents and implications for patient care are highlighted.

Drug treatment may be related to the development of adverse drug reactions (ADRs). In this paper, we evaluated the ADRs in patients admitted to Catanzaro Hospital. After we obtained the approval by local Ethical Committee, we performed a retrospective study on clinical records from March 01, 2013 to April 30, 2015. The association between drug and ADR or between drug and drug-drug-interactions (DDIs) was evaluated using the Naranjo's probability scale and Drug Interaction Probability Scale (DIPS), respectively. During the study period, we analyzed 2870 clinical records containing a total of 11,138 prescriptions, and we documented the development of 770 ADRs. The time of hospitalization was significantly higher (P<0.05) in women with ADRs (12.6 ± 1.2 days) with respect to men (11.8± 0.83 days). Using the Naranjo score, we documented a probable association in 78% of these reactions, while DIPS revealed that about 22% of ADRs were related to DDIs. Patients with ADRs received 3052 prescriptions on 11,138 (27.4%) having a mean of 6.1±0.29 drugs that was significantly higher (P<0.01) with respect to patients not experiencing ADRs (mean of 3.4±0.13 drugs). About 19% of ADRs were not diagnosed and were treated as new diseases. Our results indicate that drug administration induces the development of ADRs also during the hospitalization, particularly in elderly women. Moreover, we also documented that ADRs in some patients are under-diagnosed, therefore, it is important to motivate healthcare to report the ADRs in order to optimize the patients' safety.

Drug Use among Seniors on Public Drug Programs in Canada, 2012.

Science.gov (United States)

Proulx, Jeff; Hunt, Jordan

2015-01-01

Seniors take more drugs than younger Canadians because, on average, they have a higher number of chronic conditions. Although taking multiple medications may be necessary to manage these conditions, it is important to consider the benefits and risks of each medication and the therapeutic goals of the patient. This article provides an in-depth look at the number and types of drugs used by seniors using drug claims data from the CIHI's National Prescription Drug Utilization Information System Database, representing approximately 70% of seniors in Canada. In 2012, almost two-thirds (65.9%) of seniors on public drug programs had claims for five or more drug classes, while 27.2% had claims for 10 or more, and 8.6% had claims for 15 or more. The most commonly used drug class was statins, used by nearly half (46.6%) of seniors. Nearly two-thirds (60.9%) of seniors living in long-term care (LTC) facilities had claims for 10 or more drug classes. Proton pump inhibitors were the most commonly used drug class among seniors living in LTC facilities (used by 37.0% of seniors in LTC facilities), while statins ranked seventh (29.8%).

Williams, Christopher Ty

2016-03-01

In this article, the processing of investigational and new drug applications is described and the standard and expedited review processes are examined. The efforts of the US Food and Drug Administration to ensure greater agency transparency and fiscal responsibility and intensify oversight during the drug development and approval process are reviewed. Often attributed to a decrease in the number of uninsured adults, both the increase in prescription drug sales and the high costs associated with bringing a new drug to market highlight the necessity for a streamlined and cost-effective process to deliver these drugs safely and effectively.

Full Text Available Abstract Thailand has traditionally pursued an aggressive enforcement-based anti-illicit drug policy in an effort to make the country "drug-free." In light of this ongoing approach, we sought to assess impacts of enforcement on drug use behaviors among a cohort of injection drug users (IDU in Thailand. We examined drug use patterns among IDU participating in a cross-sectional study conducted in Bangkok (n = 252. Participants were asked to provide data regarding patterns of drug use in the previous six months, including types of drugs consumed, method of consumption, frequency of use, and weekly income spent on drugs. We also conducted bivariate analyses to identify a possible effect of a reported increase in police presence on measures of drug use and related risk behaviors among study participants. One hundred fifty-five (61.5% individuals reported injection heroin use and 132 (52.4% individuals reported injection midazolam use at least daily in the past six months. Additionally, 86 (34.1% individuals reported at least daily injection Yaba and Ice (i.e., methamphetamine use. Participants in our study reported high levels of illicit drug use, including the injection of both illicit and licit drugs. In bivariate analyses, no association between increased police presence and drug use behaviors was observed. These findings demonstrate high ongoing rates of drug injecting in Thailand despite reports of increased levels of strict enforcement and enforcement-related violence, and raise questions regarding the merits of this approach.

The structural preciseness of dendrimers makes them perfect drug delivery carriers, particularly in the form of dendrimer-drug conjugates. Current dendrimer-drug conjugates are synthesized by anchoring drug and functional moieties onto the dendrimer peripheral surface. However, functional groups exhibiting the same reactivity make it impossible to precisely control the number and the position of the functional groups and drug molecules anchored to the dendrimer surface. This structural heterogeneity causes variable pharmacokinetics, preventing such conjugates to be translational. Furthermore, the highly hydrophobic drug molecules anchored on the dendrimer periphery can interact with blood components and alter the pharmacokinetic behavior. To address these problems, we herein report molecularly precise dendrimer-drug conjugates with drug moieties buried inside the dendrimers. Surprisingly, the drug release rates of these conjugates were tailorable by the dendrimer generation, surface chemistry, and acidity. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Rings in drugs.

Taylor, Richard D; MacCoss, Malcolm; Lawson, Alastair D G

2014-07-24

We have analyzed the rings, ring systems, and frameworks in drugs listed in the FDA Orange Book to understand the frequency, timelines, molecular property space, and the application of these rings in different therapeutic areas and target classes. This analysis shows that there are only 351 ring systems and 1197 frameworks in drugs that came onto the market before 2013. Furthermore, on average six new ring systems enter drug space each year and approximately 28% of new drugs contain a new ring system. Moreover, it is very unusual for a drug to contain more than one new ring system and the majority of the most frequently used ring systems (83%) were first used in drugs developed prior to 1983. These observations give insight into the chemical novelty of drugs and potentially efficient ways to assess compound libraries and develop compounds from hit identification to lead optimization and beyond.

[Designer drugs in Jutland].

Simonsen, K W; Kaa, E

2001-04-16

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.

La contracción de las redes de contrabando de migrantes en México

2014-04-01

Full Text Available Both the official and the academic discourse argue that migrant smuggling along the border between Mexico and the United States is an increasingly complex and lucrative business that requires the operation of extensive networks with ties to organized crime. The results of this study, based on a qualitative methodology that includes in-depth interviews with 115 smugglers of migrants describe a different scenario. Smugglers of migrants have to share their profits with new actors; as a result, some migrant-smuggling networks have been forced to lay off some of their members to reduce operating costs while other networks have decided not to hire more people in order to maintain the profitability of the business.

Challenges in ensuring radiological safety and nuclear forensic for malicious acts involving nuclear and other radioactive material

International Nuclear Information System (INIS)

Sharma, Ranjit; Chatterjee, M.K.; Singh, Rajvir; Pradeepkumar, K.S.

2010-01-01

Nuclear and other radioactive materials may get smuggled into the country aimed at malicious acts. Radioactive material detected accidentally or during inspection at the entry points/national borders may indicate illicit trafficking for the purpose of nuclear/radiological terrorism. As country requires prevention and preparedness for response to these malicious acts, nuclear forensic techniques are to be developed incorporating radiological safety aspects. Nuclear forensics helps in determining the origin, intended use, legal owner and the smuggled route etc. by using fingerprinting as well as comparison with reference data. The suggested sequence of methods for analysis of radioactive material/samples will be radiological assessment, physical characterization, traditional forensic analysis, isotope analysis along with elemental/chemical analysis

Considering increased use of cardiovascular drugs and limitations in pre-marketing trials for drug safety evaluation, post marketing evaluation of adverse drug reactions (ADRs) induced by this class of medicinal products seems necessary. To determine the rate and seriousness of adverse reactions induced by cardiovascular drugs in outpatients. To compare sex and different age groups in developing ADRs with cardiovascular agents. To assess the relationship between frequencies of ADRs and the number of drugs used. This cross-sectional study was done in cardiovascular clinic at a teaching hospital. All patients during an eight months period were evaluated for cardiovascular drugs induced ADRs. Patient and reaction factors were analyzed in detected ADRs. Patients with or without ADRs were compared in sex and age by using chi-square test. Assessing the relationship between frequencies of ADRs and the number of drugs used was done by using Pearson analysis. The total number of 518 patients was visited at the clinic. ADRs were detected in 105 (20.3%) patients. The most frequent ADRs were occurred in the age group of 51-60. The highest rate of ADRs was recorded to be induced by Diltiazem (23.5%) and the lowest rate with Atenolol (3%). Headache was the most frequent detected ADR (23%). Assessing the severity and preventability of ADRs revealed that 1.1% of ADRs were detected as severe and 1.9% as preventable reactions. Women significantly developed more ADRs in this study (chi square = 3.978, PPearson=0.259, P<0.05). Monitoring ADRs in patients using cardiovascular drugs is a matter of importance since this class of medicines is usually used by elderly patients with critical conditions and underlying diseases.

2009-02-01

Drug expenditure trends in 2007 and 2008, projected drug expenditures for 2009, and factors likely to influence drug expenditures are discussed. Various factors are likely to influence drug expenditures in 2009, including drugs in development, the diffusion of new drugs, drug safety concerns, generic drugs, Medicare Part D, and changes in the drug supply chain. The increasing availability of important generic drugs and drug safety concerns continue to moderate growth in drug expenditures. The drug supply chain remains dynamic and may influence drug expenditures, particularly in specialized therapeutic areas. Initial data suggest that the Medicare Part D benefit has influenced drug expenditures, but the ultimate impact of the benefit on drug expenditures remains unclear. From 2006 to 2007, total U.S. drug expenditures increased by 4.0%, with total spending rising from $276 billion to $287 billion. Drug expenditures in clinics continue to grow more rapidly than in other settings, with a 9.9% increase from 2006 to 2007. Hospital drug expenditures increased at a moderate rate of only 1.6% from 2006 to 2007; through the first nine months of 2008, hospital drug expenditures increased by only 2.8% compared with the same period in 2007. In 2009, we project a 0-2% increase in drug expenditures in outpatient settings, a 1-3% increase in expenditures for clinic-administered drugs, and a 1-3% increase in hospital drug expenditures.

[New drug development by innovative drug administration--"change" in pharmaceutical field].

Science.gov (United States)

Nagai, T

1997-11-01

New drug development can be made by providing products of higher "selectivity for the drug" for medical treatment. There are two ways for the approach to get higher "selectivity of drug": 1) discovery of new compounds with high selectivity of drug; 2) innovation of new drug administration, that is new formulation and/or method with high selectivity of drug by integration and harmonization of various hard/soft technologies. An extensive increase of biological information and advancement of surrounding science and technology may modify the situation as the latter overcomes the former in the 21 century. As the science and technology in the 21 century is said to be formed on "3H", that is, 1. hybrid; 2. hi-quality; 3. husbandry, the new drug development by innovative drug administration is exactly based on the science and technology of 3H. Its characteristic points are interdisciplinary/interfusion, international, of philosophy/ethics, and systems of hard/hard/heart. From these points of view, not only the advance of unit technology but also a revolution in thinking way should be "must" subjects. To organize this type of research well, a total research activity such as ROR (research on research) might take an important and efficient role. Here the key words are the "Optimization technology" and "Change in Pharmaceutical Fields." As some examples of new drug innovation, our trials on several topical mucosal adhesive dosage forms and parenteral administration of peptide drugs such as insulin and erythropoietin will be described.

Non-medical use of prescription drugs among illicit drug users: A case study on an online drug forum.

Science.gov (United States)

Rönkä, Sanna; Katainen, Anu

2017-01-01

The non-medical use of prescription drugs is a growing phenomenon associated with increasing health-related harms. However, little is known about the drivers of this process among illicit drug users. Our aim is to show how the qualities of pharmaceutical drugs, pharmaceutical related knowledge, online communities sharing this knowledge and medical professionals mediate and transform the consumption behaviour related to pharmaceutical drugs. The data consist of discussion threads from an online drug use forum. Using actor network theory (ANT), we analysed translations that mediate the online user community's relationship with pharmaceutical drugs. Differences in experienced drug effects are explained both as a process of 'learning' and as differences in brain chemistry at the receptor level. Both science- and experience-based information are shared on best practices to optimise use, avoid adverse health effects and maximise the experience of intoxication. The expanded context of doctors' practices places stress on the medical framework for drug use. Our analysis shows how the non-medical use of psychoactive pharmaceuticals relates to joint, medicalised ideas of bodies as sites of medical experimentation, as well as to the collective process of constructing 'pharmaceutical competences' in user networks. Understandings of intoxication have increasingly been permeated with the pharmacological and scientific logic of knowledge. The forum works as a platform for harm reduction inspired exchange of knowledge. However, the user community's knowledge sharing practices can generate a shared perception of a sufficient or even superior drug use experience and knowledge. This may lead to overdoses and other risky behaviour, and thereby contribute to increased harms related to non-medical use of prescription drugs. Copyright © 2016 Elsevier B.V. All rights reserved.

Systematic evaluation of drug-disease relationships to identify leads for novel drug uses.

Chiang, A P; Butte, A J

2009-11-01

Drug repositioning refers to the discovery of alternative uses for drugs--uses that are different from that for which the drugs were originally intended. One challenge in this effort lies in choosing the indication for which a drug of interest could be prospectively tested. We systematically evaluated a drug treatment-based view of diseases in order to address this challenge. Suggestions for novel drug uses were generated using a "guilt by association" approach. When compared with a control group of drug uses, the suggested novel drug uses generated by this approach were significantly enriched with respect to previous and ongoing clinical trials.

Vilar, Santiago; Hripcsak, George

2017-07-01

Explosion of the availability of big data sources along with the development in computational methods provides a useful framework to study drugs' actions, such as interactions with pharmacological targets and off-targets. Databases related to protein interactions, adverse effects and genomic profiles are available to be used for the construction of computational models. In this article, we focus on the description of biological profiles for drugs that can be used as a system to compare similarity and create methods to predict and analyze drugs' actions. We highlight profiles constructed with different biological data, such as target-protein interactions, gene expression measurements, adverse effects and disease profiles. We focus on the discovery of new targets or pathways for drugs already in the pharmaceutical market, also called drug repurposing, in the interaction with off-targets responsible for adverse reactions and in drug-drug interaction analysis. The current and future applications, strengths and challenges facing all these methods are also discussed. Biological profiles or signatures are an important source of data generation to deeply analyze biological actions with important implications in drug-related studies. © The Author 2016.

da Justa Neves, Diana Brito; Caldas, Eloisa Dutra

2015-10-01

The objectives of this work were to evaluate current legislation on dietary supplements in the United States, the European Union and Brazil, and the profile of adulterated and/or irregular products on these markets. Due to a less restrictive legal framework, a supplement product that is freely available in the US may be considered a drug or even be proscribed in the EU and Brazil, thus giving rise to a clandestine market based on smuggling. From 2007 to 2014, the United States Food and Drug Administration reported 572 cases of supplement adulterations in the country, mainly products for sexual enhancement (41.6%). Data from the European Union Rapid Alert System for Food and Feed showed 929 adulterations during the same period, over 40% due to unauthorized ingredients or undeclared medicines. From 2007 to 2013, the Brazilian Federal Police Department seized 5470 supplement products, 92.2% with an American-declared origin. Qualitative chemical analyses performed on 2898 products found 180 adulterations, 41.1% due to undeclared drugs, mainly anabolic steroids, anorectics and products for erectile dysfunction, all considered medicines in Brazil. Educating the public regarding the potential risks they are taking when consuming adulterated or irregular products is necessary to protect the health of consumers. Copyright © 2015 Elsevier Inc.

Liu, Xinyue; Hatton, Randy C; Zhu, Yanmin; Hincapie-Castillo, Juan M; Bussing, Regina; Barnicoat, Marie; Winterstein, Almut G

With an increasing prevalence of psychotropic polypharmacy, clinicians depend on drug-drug interaction (DDI) references to ensure safe regimens, but the consistency of such information is frequently questioned. To evaluate the consistency of psychotropic DDIs documented in Clinical Pharmacology (CP), Micromedex (MM), and Lexicomp (LC) and summarize consistent psychotropic DDIs. In May 2016, we extracted severe or major psychotropic DDIs for 102 psychotropic drugs, including central nervous system (CNS) stimulants, antidepressants, an antimanic agent (lithium), antipsychotics, anticonvulsants, and anxiolytics-sedatives-hypnotics from CP, MM, and LC. We then summarized the psychotropic DDIs that were included in all 3 references and with evidence quality of "excellent" or "good" based on MM. We identified 1496, 938, and 1006 unique severe or major psychotropic DDIs from CP, MM, and LC, respectively. Common adverse effects related to psychotropic DDIs include increased or decreased effectiveness, CNS depression, neurotoxicity, QT prolongation, serotonin syndrome, and multiple adverse effects. Among these interactions, only 371 psychotropic DDIs were documented in all 3 references, 59 of which had "excellent" or "good" quality of evidence based on MM. The consistency of psychotropic DDI documentation across CP, MM, and LC is poor. DDI documentations need standards that would encourage consistency among drug information references. The list of the 59 DDIs may be useful in the assessment of psychotropic polypharmacy and highlighting DDI alerts in clinical practice. Copyright © 2017 American Pharmacists Association®.

Automatic extraction of drug indications from FDA drug labels.

Khare, Ritu; Wei, Chih-Hsuan; Lu, Zhiyong

2014-01-01

Extracting computable indications, i.e. drug-disease treatment relationships, from narrative drug resources is the key for building a gold standard drug indication repository. The two steps to the extraction problem are disease named-entity recognition (NER) to identify disease mentions from a free-text description and disease classification to distinguish indications from other disease mentions in the description. While there exist many tools for disease NER, disease classification is mostly achieved through human annotations. For example, we recently resorted to human annotations to prepare a corpus, LabeledIn, capturing structured indications from the drug labels submitted to FDA by pharmaceutical companies. In this study, we present an automatic end-to-end framework to extract structured and normalized indications from FDA drug labels. In addition to automatic disease NER, a key component of our framework is a machine learning method that is trained on the LabeledIn corpus to classify the NER-computed disease mentions as "indication vs. non-indication." Through experiments with 500 drug labels, our end-to-end system delivered 86.3% F1-measure in drug indication extraction, with 17% improvement over baseline. Further analysis shows that the indication classifier delivers a performance comparable to human experts and that the remaining errors are mostly due to disease NER (more than 50%). Given its performance, we conclude that our end-to-end approach has the potential to significantly reduce human annotation costs.

The therapeutic drug monitoring (TDM) of antiepileptic drugs is a tool widely used in the management of epilepsy. In Morocco, this monitoring is carried out by the Centre Anti Poison et Pharmacovigilance (CAPM) since April 1995. This is a retrospective study spanning 20 years. It concerns the therapeutic drug monitoring of Phenobarbital (PB) of carbamazepine (CBZ) and valproic acid (VPA). Therapeutic drug monitoring of the 3 antiepileptic drugs represent 58.85% of all applications received by the CAPM. The dosage of PB was ranked first followed by that of CBZ and finally by the VPA. Weak demand for therapeutic drug monitoring in Morocco could be explained by the low number of neurologists in addition to social factors. With its affordable price by patients, PB is the most prescribed antiepileptic drug in our country, which explains the high demand for its dosage. As for the therapeutic drug monitoring of the antiepileptic drug, they were mainly related to age, the occurrence of adverse effects, the association antiepileptic drugs or in the case of verification of patient compliance. Efforts are required for promoting the interests of therapeutic drug monitoring of antiepileptic drug in the management of epilepsy in Morocco.

Staphylococcus aureus is a Gram-positive bacterium that has become the leading cause of hospital acquired infections in the US. Repurposing Food and Drug Administration (FDA) approved drugs for antimicrobial therapy involves lower risks and costs compared to de novo development of novel antimicrobial agents. In this study, we examined the antimicrobial properties of two commercially available anthelmintic drugs. The FDA approved drug niclosamide and the veterinary drug oxyclozanide displayed strong in vivo and in vitro activity against methicillin resistant S. aureus (minimum inhibitory concentration (MIC): 0.125 and 0.5 μg/ml respectively; minimum effective concentration: ≤ 0.78 μg/ml for both drugs). The two drugs were also effective against another Gram-positive bacteria Enterococcus faecium (MIC 0.25 and 2 μg/ml respectively), but not against the Gram-negative species Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter aerogenes. The in vitro antimicrobial activity of niclosamide and oxyclozanide were determined against methicillin, vancomycin, linezolid or daptomycin resistant S. aureus clinical isolates, with MICs at 0.0625-0.5 and 0.125-2 μg/ml for niclosamide and oxyclozanide respectively. A time-kill study demonstrated that niclosamide is bacteriostatic, whereas oxyclozanide is bactericidal. Interestingly, oxyclozanide permeabilized the bacterial membrane but neither of the anthelmintic drugs exhibited demonstrable toxicity to sheep erythrocytes. Oxyclozanide was non-toxic to HepG2 human liver carcinoma cells within the range of its in vitro MICs but niclosamide displayed toxicity even at low concentrations. These data show that the salicylanilide anthelmintic drugs niclosamide and oxyclozanide are suitable candidates for mechanism of action studies and further clinical evaluation for treatment of staphylococcal infections.

DenguePredict: An Integrated Drug Repositioning Approach towards Drug Discovery for Dengue.

Wang, QuanQiu; Xu, Rong

2015-01-01

Dengue is a viral disease of expanding global incidence without cures. Here we present a drug repositioning system (DenguePredict) leveraging upon a unique drug treatment database and vast amounts of disease- and drug-related data. We first constructed a large-scale genetic disease network with enriched dengue genetics data curated from biomedical literature. We applied a network-based ranking algorithm to find dengue-related diseases from the disease network. We then developed a novel algorithm to prioritize FDA-approved drugs from dengue-related diseases to treat dengue. When tested in a de-novo validation setting, DenguePredict found the only two drugs tested in clinical trials for treating dengue and ranked them highly: chloroquine ranked at top 0.96% and ivermectin at top 22.75%. We showed that drugs targeting immune systems and arachidonic acid metabolism-related apoptotic pathways might represent innovative drugs to treat dengue. In summary, DenguePredict, by combining comprehensive disease- and drug-related data and novel algorithms, may greatly facilitate drug discovery for dengue.

Kaposy, Chris

2014-03-01

This article describes the shortage of generic injectable medications in Canada that affected hospitals in 2012. It traces the events leading up to the drug shortage, the causes of the shortage, and the responses by health administrators, pharmacists, and ethicists. The article argues that generic drug shortages are an ethical problem because health care organizations and governments have an obligation to avoid exposing patients to resource scarcity. The article also discusses some options governments could pursue in order to secure the drug supply and thereby fulfill their ethical obligations.

Microfluidic Devices for Drug Delivery Systems and Drug Screening

Science.gov (United States)

Kompella, Uday B.; Damiati, Safa A.

2018-01-01

Microfluidic devices present unique advantages for the development of efficient drug carrier particles, cell-free protein synthesis systems, and rapid techniques for direct drug screening. Compared to bulk methods, by efficiently controlling the geometries of the fabricated chip and the flow rates of multiphase fluids, microfluidic technology enables the generation of highly stable, uniform, monodispersed particles with higher encapsulation efficiency. Since the existing preclinical models are inefficient drug screens for predicting clinical outcomes, microfluidic platforms might offer a more rapid and cost-effective alternative. Compared to 2D cell culture systems and in vivo animal models, microfluidic 3D platforms mimic the in vivo cell systems in a simple, inexpensive manner, which allows high throughput and multiplexed drug screening at the cell, organ, and whole-body levels. In this review, the generation of appropriate drug or gene carriers including different particle types using different configurations of microfluidic devices is highlighted. Additionally, this paper discusses the emergence of fabricated microfluidic cell-free protein synthesis systems for potential use at point of care as well as cell-, organ-, and human-on-a-chip models as smart, sensitive, and reproducible platforms, allowing the investigation of the effects of drugs under conditions imitating the biological system.

The worldwide trend of using botanical drugs and strategies for developing global drugs.

Science.gov (United States)

Ahn, Kyungseop

2017-03-01

Natural product drugs, or botanical drugs, are drugs composed of natural substances which have constituents with healthenhancing or medicinal activities. In Korea, government-led projects brought attention to botanical drugs invigorating domestic botanical drug industry. Foreign markets, as well, are growing bigger as the significance of botanical drugs stood out. To follow along with the tendency, Korea puts a lot of effort on developing botanical drugs suitable for global market. However, standards for approving drug sales vary by countries. And also, thorough standardization, certification, clinical studies and data of these will be required as well as data confirming safety and effectiveness. Meanwhile, as an international exchange in botanical drug market continues, the importance of plant resources was emphasized. Thus countries' ownership of domestic natural resources became vital. Not only establishing a systematic method to secure domestic plant resources, but also cooperation with other countries on sharing natural resources is essential to procure natural resources effectively. Korea started to show visible results with botanical drugs, and asthma/COPD treatment made out of speedwell is one example. Sufficient investment and government's active support for basic infrastructure for global botanical drugs will bring Korea to much higher level of botanical drug development.

Mousavikhamene, Zeynab; Abdekhodaie, Mohammad J; Ahmadieh, Hamid

2017-10-01

A unique method was used to facilitate ocular drug delivery from periocular route by drug loaded magnetic sensitive particles. Injection of particles in periocular space along the eye axis followed by application of magnetic field in front of the eye would trigger the magnetic polymeric particles to move along the direction of magnetic force and reside against the outer surface of the sclera. This technique prevents removal of drug in the periocular space, observed in conventional transscleral drug delivery systems and hence higher amount of drug can enter the eye in a longer period of time. The experiments were performed by fresh human sclera and an experimental setup. Experimental setup was designed by side by side diffusion cell and hydrodynamic and thermal simulation of the posterior segment of the eye were applied. Magnetic polymeric particles were synthesized by alginate as a model polymer, iron oxide nanoparticles as a magnetic agent and diclofenac sodium as a model drug and characterized by SEM, TEM, DLS and FT-IR techniques. According to the SEM images, the size range of particles is around 60 to 800nm. The results revealed that the cumulative drug transfer from magnetic sensitive particles across the sclera improves by 70% in the presence of magnetic field. The results of this research show promising method of drug delivery to use magnetic properties to facilitate drug delivery to the back of the eye. Copyright © 2017. Published by Elsevier B.V.

Discontinued drugs in 2012: cardiovascular drugs.

Zhao, Hong-Ping; Jiang, Hong-Min; Xiang, Bing-Ren

2013-11-01

The continued high rate of cardiovascular morbidity and mortality has attracted wide concern and great attention of pharmaceutical industry. In order to reduce the attrition of cardiovascular drug R&D, it might be helpful recapitulating previous failures and identifying the potential factors to success. This perspective mainly analyses the 30 cardiovascular drugs dropped from clinical development in 2012. Reasons causing the termination of the cardiovascular drugs in the past 5 years are also tabulated and analysed. The analysis shows that the attrition is highest in Phase II trials and financial and strategic factors and lack of clinical efficacy are the principal reasons for these disappointments. To solve the four problems (The 'better than the Beatles' problem, the 'cautious regulator' problem, the 'throw money at it' tendency and the 'basic researchbrute force' bias) is recommended as the main measure to increase the number and quality of approvable products.

[Are there any sex/gender differences in drug use and drug addiction?].

Science.gov (United States)

Mendrek, Adrianna

Drug use and drug addiction have been traditionally considered to be a male problem, however the gender gap has been decreasing over the past few decades. Thus, while the prevalence of alcohol, cannabis and nicotine dependence is still overall greater among men than among women, sex/gender differences in the abuse of stimulants and opiates seem to have disappeared. Moreover, women appear to be more prone to develop drug dependence, suffer more severe physical and psychological consequences of drug abuse, and have more difficulties quitting the habit. Numerous psychological, socio-cultural and biological factors have been implicated in these changing statistics. For example, while a large proportion of men initiate drug use to induce feelings of elation, energy or focus, women frequently start taking drugs to alleviate pre-existing mental health problems, including high levels of stress, feelings of alienation, depression, anxiety, or post-traumatic stress disorder. This maladaptive self-medication strategy often results in a faster transition to a habitual drug use and eventually a more severe dependence. In addition, the socio-cultural norms (particularly in the Western society) have changed dramatically over the past few decades. Thus, while there is still a more severe stigma and prejudice against women who use drugs (especially if they are pregnant of have children), overall there is much greater acceptance of women's drug use than it was several decades ago. Moreover, women have much greater access to various drugs of abuse than they used to have. Finally, over the past couple of decades new research started emerging pointing to some neurobiological factors that could also contribute to sex differences in drug addiction. Thus, there is now evidence that dopamine system, which for decades has been strongly implicated in drug reinforcement, is sexually dimorphic. The number of dopaminergic neurons, the density of the dopaminergic terminals, as well as

Mexico's "ley de narcomenudeo" drug policy reform and the international drug control regime.

Science.gov (United States)

Mackey, Tim K; Werb, Daniel; Beletsky, Leo; Rangel, Gudelia; Arredondo, Jaime; Strathdee, Steffanie A

2014-11-14

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.

Miyasaka Lincoln Sakiara

2003-01-01

Full Text Available OBJECTIVE: To assess the frequency of combination of antidepressants with other drugs and risk of drug interactions in the setting public hospital units in Brazil. METHODS: Prescriptions of all patients admitted to a public hospital from November 1996 to February 1997 were surveyed from the hospital's data processing center in São Paulo, Brazil. A manual search of case notes of all patients admitted to the psychiatric unit from January 1993 to December 1995 and all patients registered in the affective disorders outpatient clinic in December 1996 was carried out. Patients taking any antidepressant were identified and concomitant use of drugs was checked. By means of a software program (Micromedex® drug interactions were identified. RESULTS: Out of 6,844 patients admitted to the hospital, 63 (0.9% used antidepressants and 16 (25.3% were at risk of drug interaction. Out of 311 patients in the psychiatric unit, 63 (20.2% used antidepressants and 13 of them (20.6% were at risk. Out of 87 patients in the affective disorders outpatient clinic, 43 (49.4% took antidepressants and 7 (16.2% were at risk. In general, the use of antidepressants was recorded in 169 patients and 36 (21.3% were at risk of drug interactions. Twenty different forms of combinations at risk of drug interactions were identified: four were classified as mild, 15 moderate and one severe interaction. CONCLUSION: In the hospital general units the number of drug interactions per patient was higher than in the psychiatric unit; and prescription for depression was lower than expected.

Drug accumulation by means of noninvasive magnetic drug delivery system

International Nuclear Information System (INIS)

Chuzawa, M.; Mishima, F.; Akiyama, Y.; Nishijima, S.

2011-01-01

The medication is one of the most general treatment methods, but drugs diffuse in the normal tissues other than the target part by the blood circulation. Therefore, side effect in the medication, particularly for a drug with strong effect such as anti-cancer drug, are a serious issue. Drug Delivery System (DDS) which accumulates the drug locally in the human body is one of the techniques to solve the side-effects. Magnetic Drug Delivery System (MDDS) is one of the active DDSs, which uses the magnetic force. The objective of this study is to accumulate the ferromagnetic drugs noninvasively in the deep part of the body by using MDDS. It is necessary to generate high magnetic field and magnetic gradient at the target part to reduce the side-effects to the tissues with no diseases. The biomimetic model was composed, which consists of multiple model organs connected with diverged blood vessel model. The arrangement of magnetic field was examined to accumulate ferromagnetic drug particles in the target model organ by using a superconducting bulk magnet which can generate high magnetic fields. The arrangement of magnet was designed to generate high and stable magnetic field at the target model organ. The accumulation experiment of ferromagnetic particles has been conducted. In this study, rotating HTS bulk magnet around the axis of blood vessels by centering on the target part was suggested, and the model experiment for magnet rotation was conducted. As a result, the accumulation of the ferromagnetic particles to the target model organ in the deep part was confirmed.

Enhanced drug delivery capabilities from stents coated with absorbable polymer and crystalline drug.

2012-09-28

Current drug eluting stent (DES) technology is not optimized with regard to the pharmacokinetics of drug delivery. A novel, absorbable-coating sirolimus-eluting stent (AC-SES) was evaluated for its capacity to deliver drug more evenly within the intimal area rather than concentrating drug around the stent struts and for its ability to match coating erosion with drug release. The coating consisted of absorbable poly-lactide-co-glycolic acid (PLGA) and crystalline sirolimus deposited by a dry-powder electrostatic process. The AC-SES demonstrated enhanced drug stability under simulated use conditions and consistent drug delivery balanced with coating erosion in a porcine coronary implant model. The initial drug burst was eliminated and drug release was sustained after implantation. The coating was absorbed within 90 days. Following implantation into porcine coronary arteries the AC-SES coating is distributed in the surrounding intimal tissue over the course of several weeks. Computational modeling of drug delivery characteristics demonstrates how distributed coating optimizes the load of drug immediately around each stent strut and extends drug delivery between stent struts. The result was a highly efficient arterial uptake of drug with superior performance to a clinical bare metal stent (BMS). Neointimal thickness (0.17±0.07 mm vs. 0.28±0.11 mm) and area percent stenosis (22±9% vs. 35±12%) were significantly reduced (pstent implantation in an overlap configuration in porcine coronary arteries. Inflammation was significantly reduced in the AC-SES compared to the BMS at both 30 and 90 days after implantation. Biocompatible, rapidly absorbable stent coatings enable the matching of drug release with coating erosion and provide for the controlled migration of coating material into tissue to reduce vicissitudes in drug tissue levels, optimizing efficacy and reducing potential toxicity.

Evaluation of drug interaction microcomputer software: Dambro's Drug Interactions.

Science.gov (United States)

Poirier, T I; Giudici, R A

1990-01-01

Dambro's Drug Interactions was evaluated using general and specific criteria. The installation process, ease of learning and use were rated excellent. The user documentation and quality of the technical support were good. The scope of coverage, clinical documentation, frequency of updates, and overall clinical performance were fair. The primary advantages of the program are the quick searching and detection of drug interactions, and the attempt to provide useful interaction data, i.e., significance and reference. The disadvantages are the lack of current drug interaction information, outdated references, lack of evaluative drug interaction information, and the inability to save or print patient profiles. The program is not a good value for the pharmacist but has limited use as a quick screening tool.

[Drug induced diarrhea].

Morard, Isabelle; Hadengue, Antoine

2008-09-03

Diarrhea is a frequent adverse event involving the most frequently antibiotics, laxatives and NSAI. Drug induced diarrhea may be acute or chronic. It may be due to expected, dose dependant properties of the drug, to immuno-allergic or bio-genomic mechanisms. Several pathophysiological mechanisms have been described resulting in osmotic, secretory or inflammatory diarrhea, shortened transit time, or malabsorption. Histopathological lesions sometimes associated with drug induced diarrhea are usually non specific and include ulcerations, inflammatory or ischemic lesions, fibrous diaphragms, microscopic colitis and apoptosis. The diagnosis of drug induced diarrhea, sometimes difficult to assess, relies on the absence of other obvious causes and on the rapid disappearance of the symptoms after withdrawal of the suspected drug.

Predicting adverse drug reaction profiles by integrating protein interaction networks with drug structures.

Science.gov (United States)

Huang, Liang-Chin; Wu, Xiaogang; Chen, Jake Y

2013-01-01

The prediction of adverse drug reactions (ADRs) has become increasingly important, due to the rising concern on serious ADRs that can cause drugs to fail to reach or stay in the market. We proposed a framework for predicting ADR profiles by integrating protein-protein interaction (PPI) networks with drug structures. We compared ADR prediction performances over 18 ADR categories through four feature groups-only drug targets, drug targets with PPI networks, drug structures, and drug targets with PPI networks plus drug structures. The results showed that the integration of PPI networks and drug structures can significantly improve the ADR prediction performance. The median AUC values for the four groups were 0.59, 0.61, 0.65, and 0.70. We used the protein features in the best two models, "Cardiac disorders" (median-AUC: 0.82) and "Psychiatric disorders" (median-AUC: 0.76), to build ADR-specific PPI networks with literature supports. For validation, we examined 30 drugs withdrawn from the U.S. market to see if our approach can predict their ADR profiles and explain why they were withdrawn. Except for three drugs having ADRs in the categories we did not predict, 25 out of 27 withdrawn drugs (92.6%) having severe ADRs were successfully predicted by our approach. © 2012 WILEY-VCH Verlag GmbH & Co.

Drugs in breast milk.

Science.gov (United States)

Hervada, A R; Feit, E; Sagraves, R

1978-09-01

The amount of drug excreted into breast milk is dependent upon the lipid solubility of the medication, the mechanism of transport, the degree of ionization, and change in plasma pH. The higher the lipid solubility, the greater the concentration in human milk. The majority of drugs are transported into mammary blood capillaries by passive diffusion. The rest are transported by reverse pinocytosis. Once the drug has entered the epithelial cells of breast tissue, the drug molecules are excreted into the human milk by active transport, passive diffusion, or apocrine secretion. The amount of free (active) drug available for transport depends on the degree of protein binding the plasma pH. Another factor affecting excretion of drugs is the time when breast feeding occurs. In the 1st few days of life, when colostrum is present, water-soluble drugs pass through the breast more easily than afterwards when milk is produced. Then lipid-soluble drugs cross in higher concentrations. The effect on nursing infants is dependent on the amount excreted into the milk, the total amount absorbed by the infant, and the toxicity of the drug. The use of the following drugs in breast feeding mothers is reviewed: anticoagulants, antihypertensives and diuretics, antimicrobials, drugs affecting the central nervous system (alcohol, chloral hydrate, meprobamate, lithium, and aspirin), marijuana, other drugs (antihistamines, atropine, ergot alkaloids, laxatives, nicotine, iodides, propylthiouracil, theophylline), hormones (insulin, thyroxine, and oral contraceptives), and radiopharmaceuticals.

Drug detection in breath: non-invasive assessment of illicit or pharmaceutical drugs.

Breath analysis not only holds great potential for the development of new non-invasive diagnostic methods, but also for the identification and follow up of drug levels in breath. This is of interest for both, forensic and medical science. On the one hand, the detection of drugs of abuse in exhaled breath-similar to the well-known breath alcohol tests-would be highly desirable as an alternative to blood or urine analysis in situations such as police controls for drugged driving. The non-invasive detection of drugs and their metabolites is thus of great interest in forensic science, especially since marijuana is becoming legalized in certain parts of the US and the EU. The detection and monitoring of medical drugs in exhaled breath without the need of drawing blood samples on the other hand, is of high relevance in the clinical environment. This could facilitate a more precise medication and enable therapy control without any burden to the patient. Furthermore, it could be a step towards personalized medicine. This review gives an overview of the current state of drug detection in breath, including both volatile and non-volatile substances. The review is divided into two sections. The first section deals with qualitative detection of drugs (drugs of abuse), while the second is related to quantitative drug detection (medical drugs). Chances and limitations are discussed for both aspects. The detection of the intravenous anesthetic propofol is presented as a detailed example that demonstrates the potential, requirements, pitfalls and limitations of therapeutic drug monitoring by means of breath analysis.

Text mining and data integration methods are gaining ground in the field of health sciences due to the exponential growth of bio-medical literature and information stored in biological databases. While such methods mostly try to extract bioentity associations from PubMed, very few of them are dedicated in mining other types of repositories such as chemical databases. Herein, we apply a text mining approach on the DrugBank database in order to explore drug associations based on the DrugBank "Description", "Indication", "Pharmacodynamics" and "Mechanism of Action" text fields. We apply Name Entity Recognition (NER) techniques on these fields to identify chemicals, proteins, genes, pathways, diseases, and we utilize the TextQuest algorithm to find additional biologically significant words. Using a plethora of similarity and partitional clustering techniques, we group the DrugBank records based on their common terms and investigate possible scenarios why these records are clustered together. Different views such as clustered chemicals based on their textual information, tag clouds consisting of Significant Terms along with the terms that were used for clustering are delivered to the user through a user-friendly web interface. DrugQuest is a text mining tool for knowledge discovery: it is designed to cluster DrugBank records based on text attributes in order to find new associations between drugs.

García, A J; Martos, F; Leiva, F; Sánchez de la Cuesta, F

2003-01-01

In this article we analyze the responses of 1220 Spanish physicians who participated in a survery about generic drugs. A previously validated questionnaire was sent to physicians through the Spanish Medical Councils of the different provinces. Four items were analyzed: what doctors know about generic drugs (knowledge); physicians' prescribing habits concerning these drugs (attitude and professional competence); how prescription of generic drugs effects pharmaceutical costs amd, finally, what doctors believe a generic drug should be. The influence of physician-related variables (age, type of contract, specialty, workload, etc.) on prescribing of generic drugs was also analyzed. In view of the results, we believe that to rationalize expenditure through and appropriate policy on generic drugs Spanish health authorities should offer more and better training and information (clear and independent) about what generic drugs are.

Random drug testing of people being treated for chronic pain has become more common. Physicians may drug test patients on opioid therapy as a result of concerns over prosecution, drug misuse, addiction, and overdose. However, profit motive has remained unexplored. This article suggests profits also drive physician drug-testing behavior and evidence is offered, including an exploration of Medicare reimbursement incentives and kickbacks for drug testing.

A Novel Drug-Mouse Phenotypic Similarity Method Detects Molecular Determinants of Drug Effects.

Directory of Open Access Journals (Sweden)

Jeanette Prinz

Full Text Available The molecular mechanisms that translate drug treatment into beneficial and unwanted effects are largely unknown. We present here a novel approach to detect gene-drug and gene-side effect associations based on the phenotypic similarity of drugs and single gene perturbations in mice that account for the polypharmacological property of drugs. We scored the phenotypic similarity of human side effect profiles of 1,667 small molecules and biologicals to profiles of phenotypic traits of 5,384 mouse genes. The benchmarking with known relationships revealed a strong enrichment of physical and indirect drug-target connections, causative drug target-side effect links as well as gene-drug links involved in pharmacogenetic associations among phenotypically similar gene-drug pairs. The validation by in vitro assays and the experimental verification of an unknown connection between oxandrolone and prokineticin receptor 2 reinforces the ability of this method to provide new molecular insights underlying drug treatment. Thus, this approach may aid in the proposal of novel and personalized treatments.

To identify and evaluate the frequency, severity, mechanism and common pairs of drug-drug interactions (DDIs) in prescriptions by consultants in medicine outpatient department. This cross sectional descriptive study was done by Pharmacology department of Bahria University Medical & Dental College (BUMDC) in medicine outpatient department (OPD) of a private hospital in Karachi from December 2015 to January 2016. A total of 220 prescriptions written by consultants were collected. Medications given with patient's diagnosis were recorded. Drugs were analyzed for interactions by utilizing Medscape drug interaction checker, drugs.com checker and stockley`s drug interactions index. Two hundred eleven prescriptions were selected while remaining were excluded from the study because of unavailability of the prescribed drugs in the drug interaction checkers. In 211 prescriptions, two common diagnoses were diabetes mellitus (28.43%) and hypertension (27.96%). A total of 978 medications were given. Mean number of medications per prescription was 4.6. A total of 369 drug-drug interactions were identified in 211 prescriptions (175%). They were serious 4.33%, significant 66.12% and minor 29.53%. Pharmacokinetic and pharmacodynamic interactions were 37.94% and 51.21% respectively while 10.84% had unknown mechanism. Number wise common pairs of DDIs were Omeprazole-Losartan (S), Gabapentine- Acetaminophen (M), Losartan-Diclofenac (S). The frequency of DDIs is found to be too high in prescriptions of consultants from medicine OPD of a private hospital in Karachi. Significant drug-drug interactions were more and mostly caused by Pharmacodynamic mechanism. Number wise evaluation showed three common pairs of drugs involved in interactions.

Drug metabolism and ageing.

Wynne, Hilary

2005-06-01

Older people are major consumers of drugs and because of this, as well as co-morbidity and age-related changes in pharmacokinetics and pharmacodynamics, are at risk of associated adverse drug reactions. While age does not alter drug absorption in a clinically significant way, and age-related changes in volume of drug distribution and protein binding are not of concern in chronic therapy, reduction in hepatic drug clearance is clinically important. Liver blood flow falls by about 35% between young adulthood and old age, and liver size by about 24-35% over the same period. First-pass metabolism of oral drugs avidly cleared by the liver and clearance of capacity-limited hepatically metabolized drugs fall in parallel with the fall in liver size, and clearance of drugs with a high hepatic extraction ratio falls in parallel with the fall in hepatic blood flow. In normal ageing, in general, activity of the cytochrome P450 enzymes is preserved, although a decline in frail older people has been noted, as well as in association with liver disease, cancer, trauma, sepsis, critical illness and renal failure. As the contribution of age, co-morbidity and concurrent drug therapy to altered drug clearance is impossible to predict in an individual older patient, it is wise to start any drug at a low dose and increase this slowly, monitoring carefully for beneficial and adverse effects.

Recent trends for drug lag in clinical development of oncology drugs in Japan: does the oncology drug lag still exist in Japan?

Science.gov (United States)

Maeda, Hideki; Kurokawa, Tatsuo

2015-12-01

This study exhaustively and historically investigated the status of drug lag for oncology drugs approved in Japan. We comprehensively investigated oncology drugs approved in Japan between April 2001 and July 2014, using publicly available information. We also examined changes in the status of drug lag between Japan and the United States, as well as factors influencing drug lag. This study included 120 applications for approval of oncology drugs in Japan. The median difference over a 13-year period in the approval date between the United States and Japan was 875 days (29.2 months). This figure peaked in 2002, and showed a tendency to decline gradually each year thereafter. In 2014, the median approval lag was 281 days (9.4 months). Multiple regression analysis identified the following potential factors that reduce drug lag: "Japan's participation in global clinical trials"; "bridging strategies"; "designation of priority review in Japan"; and "molecularly targeted drugs". From 2001 to 2014, molecularly targeted drugs emerged as the predominant oncology drug, and the method of development has changed from full development in Japan or bridging strategy to global simultaneous development by Japan's taking part in global clinical trials. In line with these changes, the drug lag between the United States and Japan has significantly reduced to less than 1 year.

Full Text Available BACKGROUND The geriatric population is increasing as a result of advanced medical facilities. This population also faces a number of medical health challenges. They tend to receive multiple medications often leading to Drug-Drug Interactions (DDIs Adverse Drug Reactions (ADRs and other clinical consequences, which compromises their quality of life if not endangering it as well. There are few Indian studies focusing on this problem. Hence, this study was undertaken with the aim to assess the polypharmacy pattern, proportion of DDIs and adverse drug reactions in the geriatric population in a tertiary care hospital. MATERIALS AND METHODS This was a cross-sectional study wherein data from 201 geriatric inpatient’s prescriptions were collected. The prescriptions were assessed for demographic details such as age, gender, comorbidities and drugs prescribed. All prescriptions were evaluated for polypharmacy, DDIs and ADRs. DDIs were assessed using Micromedex software. Patients were stratified into groups and DDIs were compared between the groups, gender and also with number of drugs used. RESULTS There were 201 patients with a mean age of approximately 70 years. Polypharmacy occurred in 73.63% of them with mean number of drugs being 6.23. The number of drugs used increased significantly with age (p=0.0001. Hypertension was the most common comorbidity. Polypharmacy was strongly associated with hypertension and dyslipidaemia. A total of 129 (64.17% patients accounted for 425 potential DDIs. The most common drug involved in DDIs was aspirin. A subset analysis of ADRs showed an occurrence of 50.68% with 10.81% being definitely avoidable. CONCLUSION Elderly individuals are at increased risk of being on polypharmacy. This comes with the risk of several potential DDIs, which in turn may lead to adverse drug reactions, which results in morbidity. Doctors involved in the care of the elderly should be aware of these facts and exercise caution while adding any

More than 20% of clinically used drugs are glucuronidated by a microsomal enzyme UDP-glucuronosyltransferase (UGT). Inhibition or induction of UGT can result in an increase or decrease in blood drug concentration. To avoid drug-drug interactions and adverse drug reactions in individuals, therefore, it is important to understand whether UGTs are involved in metabolism of drugs and drug candidates. While most of glucuronides are inactive metabolites, acyl-glucuronides that are formed from compounds with a carboxylic acid group can be highly toxic. Animals such as mice and rats are widely used to predict drug metabolism and drug-induced toxicity in humans. However, there are marked species differences in the expression and function of drug-metabolizing enzymes including UGTs. To overcome the species differences, mice in which certain drug-metabolizing enzymes are humanized have been recently developed. Humanized UGT1 (hUGT1) mice were created in 2010 by crossing Ugt1-null mice with human UGT1 transgenic mice in a C57BL/6 background. hUGT1 mice can be promising tools to predict human drug glucuronidation and acyl-glucuronide-associated toxicity. In this review article, studies of drug metabolism and toxicity in the hUGT1 mice are summarized. We further discuss research and strategic directions to advance the understanding of drug glucuronidation in humans. Copyright © 2017 The Japanese Society for the Study of Xenobiotics.

2011-01-01

Full Text Available Numerous nanocarriers of various compositions and geometries have been developed for the delivery and release of therapeutic and imaging agents. Due to the high specific surface areas of nanocarriers, different mechanisms such as ion pairing and hydrophobic interaction need to be explored for achieving sustained release. Recently, we developed a three-parameter model that considers reversible drug-carrier interaction and first-order drug release from liposomes. A closed-form analytical solution was obtained. Here, we further explore the ability of the model to capture the release of bioactive molecules such as drugs and growth factors from various nanocarriers. A parameter study demonstrates that the model is capable of resembling major categories of drug release kinetics. We further fit the model to 60 sets of experimental data from various drug release systems, including nanoparticles, hollow particles, fibers, and hollow fibers. Additionally, bootstrapping is used to evaluate the accuracy of parameter determination and validate the model in selected cases. The simplicity and universality of the model and the clear physical meanings of each model parameter render the model useful for the design and development of new drug delivery systems.
