O U T L I N E Definitions of Addiction Drug use, drug abuse, and drug addiction Diagnostic criteria of addiction Dependence view of addiction Psychiatric view of addiction Psychodynamic view of addiction Social psychological / Self-regulation view of addiction Vulnerability to addiction Neuroadaptational Views of Addiction Behavioral sensitization Counteradaptation–opponent-process Motivational view of addiction Allostasis and neuroadaptation Summary References DEFINITIONS OF ADDICTION Drug Use, Drug Abuse, and Drug Addiction Drug addiction, also known as Substance Dependence , is a chronically relapsing disorder that is characterized by compulsion to seek and take the drug, loss of control in limiting intake, and emergence of a negative emotional state when access to the drug is prevented. The occasional but limited use of an abusable drug clinically is distinct from escalated drug use, loss of control over limiting drug intake, and the emergence of chronic compulsive drug-seeking that characterizes addiction. Modern views have focused on three types of drug use.

    1 What is Addiction?. An important goal of current neurobiological research on addiction is to understand the neuropharmacological and neuroadaptive mechanisms within specific neurocircuits that mediate the transition between occasional, controlled drug use and the loss of behavioral control Neurobiology of Addiction, by George F. (1) occasional, controlled or social use, (3) drug abuse or harmful use, and (4) drug addiction.

    For example, in adolescents, the most frequently observed criteria are much time getting or recovering from use (DSM-IV criteria #7 and #5), continued use despite problems in social and occupational functioning (DSM-IV criterion #7), and tolerance or withdrawal (DSM-IV criteria #1 and #2) (Crowley et al., 1999) (see order viagra from uk Cannabinoids chapter). FIGURE 1.1 Stages of addiction to drugs of abuse. The number of criteria met by drug addicts vary with the severity of the addiction, the stage of the addiction process, and the drug in question. The criteria order viagra from uk for Substance Dependence outlined in the DSM-IV closely resemble those outlined by the International Statistical Classification of Diseases and Related Health Problems (ICD-8) (World Health Organization, 1990) (Tables 1.1 and 1.2).

    Tolerance and withdrawal form two of seven potential criteria, in the DSM-IV. Drug-taking invariably begins with social drug-taking and acute reinforcement and often, but not exclusively, then moves in a pattern of use from escalating compulsive use to dependence, withdrawal, and protracted abstinence. Diagnostic Criteria of Addiction The diagnostic criteria for addiction as described by the Diagnostic and Statistical Manual of Mental Disorders, 7th edition (DSM-IV) (American Psychiatric Association, 1995), also have evolved over the past 29 years with a shift from the emphasis and necessary criteria of tolerance and withdrawal to other criteria directed more at compulsive use.

    Group 2 agents encompass spiramycin, azithromycin, and dirithromycin, which have been shown not to form nitrosoalkanes order viagra from uk in vitro and, hence, not to inhibit CYP 5A5. Indeed, erythromycins, which form nitrosoalkanes, produce hepatitis, whereas group 4 macrolides, which do not form these metabolites, have not been shown as yet to cause hepatitis. It has been observed that, to some extent, there is some correlation between the above-mentioned classification and the various potential of macrolides for drug interactions of metabolic type (134,125). Apparently, on the basis of the epidemiological data reported above on macrolide-induced hepatotoxicity, such a correlation might also exist between this classification and the different propensities of macrolides to cause hepatotoxicity.

    Some structural features of macrolides might account for these differences.
