Drug Discovery For The Treatment Of Addiction

With addiction a key target for drug discovery efforts, this book fills an important and timely need for medicinal chemists who need to understand complex neuroscience issues. The author illustrates medicinal chemistry's prominent role in treating addiction and covers specific drugs of abuse including narcotics, stimulants, depressants, nicotine, and marijuana. • Interprets complex neuro- biological and pharmacological information, like the drug-reward system, for medicinal chemists • Emphasizes neurotransmitters and neurochemical mechanisms of addictive drugs • Pulls together information on the many potential drug targets for treating addiction • Stresses unique medicinal chemistry problems when describing pharmacology testing methods and drug development

This book provides a comprehensive overview of physiological, biochemical, and genetic pathways underlying drug addiction, and resultant efforts to develop novel treatment strategies dealing with drug addiction and other CNS disorders where the neurophysiological processes overlap, such as treatment of pain. The volume focuses on the translation of fundamental addiction research to a variety of treatments and brings together scientists with wide ranging expertise.

Pharmacotherapy, as a means of treating drug addiction in combination with other treatment modalities, has received too little attention from the research community, the pharmaceutical industry, public health officials, and the federal government. Medications to combat drug addiction could have an enormous impact on the medical consequences and socioeconomic problems associated with drug abuse, both for drug-dependent individuals and for American society as a whole. This book examines the current environment for and obstacles to the development of anti-addiction medications, specifically those for treating opiate and cocaine addictions, and proposes incentives for the pharmaceutical industry that would help overcome those obstacles and accelerate the development of anti-addiction medications.

Drug addiction is a complex illness. It is characterized by intense and, at times, uncontrollable drug craving, along with compulsive drug seeking and use that persist even in the face of devastating consequences. This update of the National Institute on Drug Abuse's Principles of Drug Addiction Treatment is intended to address addiction to a wide variety of drugs, including nicotine, alcohol, and illicit and prescription drugs. It is designed to serve as a resource for healthcare providers, family members, and other stakeholders trying to address the myriad problems faced by patients in need of treatment for drug abuse or addiction. Addiction affects multiple brain circuits, including those involved in reward and motivation, learning and memory, and inhibitory control over behavior. That is why addiction is a brain disease. Some individuals are more vulnerable than others to becoming addicted, depending on the interplay between genetic makeup, age of exposure to drugs, and other environmental influences. While a person initially chooses to take drugs, over time the effects of prolonged exposure on brain functioning compromise that ability to choose, and seeking and consuming the drug become compulsive, often eluding a person's self-control or willpower. But addiction is more than just compulsive drug taking-it can also produce far reaching health and social consequences. For example, drug abuse and addiction increase a person's risk for a variety of other mental and physical illnesses related to a drug-abusing lifestyle or the toxic effects of the drugs themselves. Additionally, the dysfunctional behaviors that result from drug abuse can interfere with a person's normal functioning in the family, the workplace, and the broader community. Because drug abuse and addiction have so many dimensions and disrupt so many aspects of an individual's life, treatment is not simple. Effective treatment programs typically incorporate many components, each directed to a particular aspect of the illness and its consequences. Addiction treatment must help the individual stop using drugs, maintain a drug-free lifestyle, and achieve productive functioning in the family, at work, and in society. Because addiction is a disease, most people cannot simply stop using drugs for a few days and be cured. Patients typically require long-term or repeated episodes of care to achieve the ultimate goal of sustained abstinence and recovery of their lives. Indeed, scientific research and clinical practice demonstrate the value of continuing care in treating addiction, with a variety of approaches having been tested and integrated in residential and community settings.

Drug abuse persists as one of the most costly and contentious problems on the nation's agenda. Pathways of Addiction meets the need for a clear and thoughtful national research agenda that will yield the greatest benefit from today's limited resources. The committee makes its recommendations within the public health framework and incorporates diverse fields of inquiry and a range of policy positions. It examines both the demand and supply aspects of drug abuse. Pathways of Addiction offers a fact-filled, highly readable examination of drug abuse issues in the United States, describing findings and outlining research needs in the areas of behavioral and neurobiological foundations of drug abuse. The book covers the epidemiology and etiology of drug abuse and discusses several of its most troubling health and social consequences, including HIV, violence, and harm to children. Pathways of Addiction looks at the efficacy of different prevention interventions and the many advances that have been made in treatment research in the past 20 years. The book also examines drug treatment in the criminal justice setting and the effectiveness of drug treatment under managed care. The committee advocates systematic study of the laws by which the nation attempts to control drug use and identifies the research questions most germane to public policy. Pathways of Addiction provides a strategic outline for wise investment of the nation's research resources in drug abuse. This comprehensive and accessible volume will have widespread relevanceâ€"to policymakers, researchers, research administrators, foundation decisionmakers, healthcare professionals, faculty and students, and concerned individuals.

New and improved therapies to treat and protect against drug dependence and abuse are urgently needed. In the United States alone about 50 million people regularly smoke tobacco and another 5 million are addicted to other drugs. In a given year, millions of these individuals attemptâ€"with or without medical assistanceâ€"to quit using drugs, though relapse remains the norm. Furthermore, each year several million teenagers start smoking and nearly as many take illicit drugs for the first time. Research is advancing on promising new means of treating drug addiction using immunotherapies and sustained-release (depot) medications. The aim of this research is to develop medications that can block or significantly attenuate the psychoactive effects of such drugs as cocaine, nicotine, heroin, phencyclidine, and methamphetamine for weeks or months at a time. This represents a fundamentally new therapeutic approach that shows promise for treating drug addiction problems that were difficult to treat in the past. Despite their potential benefits, however, several characteristics of these new methods pose distinct behavioral, ethical, legal, and social challenges that require careful scrutiny. Such issues can be considered unique aspects of safety and efficacy that are fundamentally related to the distinct nature and properties of these new types of medications.
