Abstract
The cocaine epidemic has stimulated novel treatments aimed at reducing relapse to this extremely addicting drug. After detoxification and standard treatment, former cocaine users continue to exhibit strong cocaine craving and physiological changes when presented with cocaine-related stimuli. Because these conditioned responses may increase the risk of relapse, a new treatment has been developed to extinguish such responses. The extinction process, consisting of repeated presentations of cocaine-related stimuli until the stimuli gradually lose their ability to evoke conditioned responses, is integrated into a comprehensive rehabilitation program. Cocaine dependence is often combined with opiate dependence. Desipramine has been added to methadone maintenance in an attempt to reduce dependence on both substances. Methadone impedes catabolism of desipramine so that relatively low doses of desipramine may produce antidepressant effects and possibly reduce the desire to use cocaine. Preliminary evidence from a placebo-controlled study of desipramine in combination with methadone suggests that desipramine produces significant improvements in psychological functioning, but its effects on reduction of cocaine use are less dramatic.
