High‐ and Low‐Dose Mazindol for Cocaine Dependence in Methadone‐Maintained Patients: A Preliminary Evaluation

Abstract
We conducted a preliminary investigation comparing high‐dose mazindol (8 mg/day), low dose mazindol (1 mg/day), and placebo for cocaine abstinence initiation in a 12‐week, double‐blind, randomized clinical trial enrolling 17 cocaine‐dependent, methadone‐maintained patients. Outcome data did not support a difference between the two dose levels on percentage positive urine screens positive for cocaine (1 mg mazindol=68%, 8 mg mazindol=75%, placebo=91%). Doses of mazindol greater than 8 mg may be needed for a cocaine blocking effect, although potential pressor effects may be a limiting factor.
