title: Diethylpropion pharmacotherapeutic adjuvant therapy for inpatient treatment of cocaine dependence: a test of the cocaine-agonist hypothesis.
abstract: Fifty cocaine-dependent patients completed a 2-week double-blind, double-dummy, parallel-group comparison of four dosage levels of diethylpropion and placebo. This clinical trial was designed to evaluate both diethylpropion's ability to attenuate cocaine cue-induced craving and its potential for development as a medication with cocaine-agonist properties. The results indicated that diethylpropion was not superior to placebo and confirmed earlier reports that craving for cocaine diminishes over the course of an inpatient hospitalization. Moreover, the results showed that the cocaine cue-induced craving paradigm employed is effective in stimulating craving for cocaine. Medications that are effective in attenuating this type of "conditioned" craving may have relevance to the breaking of the cycle of relapse and long-term treatment of cocaine dependence. Diethylpropion may not be an appropriate candidate for future medication development because of its lack of obvious therapeutic efficacy and the emergence of a significant number of side effects. However, a cocaine-agonist medication strategy may be appropriate for a subgroup of cocaine-dependent patients with coexisting attention deficit-hyperactivity disorder.
