Purpose

The aim of this study is to assess the efficacy of caffeine compared to placebo as a maintenance treatment for cocaine dependence. Caffeine potentiation with biperiden will be also studied.

Ninety patients with snorted/sniffed cocaine dependence will be randomized to receive caffeine (300 - 1200 mg t.i.d.) plus biperidene (8 mg b.i.d.) caffeine (300 - 1200 mg t.i.d.) with placebo or placebo during 10 days in an in-hospital setting.
