Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

OBJECTIVES: I. Determine whether the benzodiazepine alprazolam reinforces self-medication behavior in anxious patients with varying histories of using other drugs. II. Establish outpatient methods for the study of self-medication and drug reinforcement in patients vulnerable to prescription drug abuse or dependence. III. Evaluate the influence of alcohol and other non-prescription drug use as determinants of vulnerability in these patients. IV. Identify personality, attitudinal, or other variables that might predict different patterns of self-medication. V. Assess the effects of cognitive-behavioral therapy on alprazolam self-medication.
