Study type
Interventional
Description of intervention(s) / exposure
Patients entered into the trial will be randomized to receive either Bioeffective A 320mg three times daily (1 capsule three times daily) or placebo 1 capsule three times daily for the full 12 weeks duration of the trial. The trial will examine the effect of Bioeffective A versus placebo during two phases of treatment; Phase 1: acute alcohol withdrawal (defined as the first 7 days following cessation of alcohol intake), and Phase 2: the subsequent 11 weeks of alcohol abstinence maintenance. During Phase 1 (acute alcohol withdrawal) the trial will examine the effect of Bioeffective A versus placebo on the outcome of conventional treatment of alcohol withdrawal in which all subjects will receive benzodiazepines prescribed as needed according to the severity of alcohol withdrawal as measured by the Clinical Institute Withdrawal Assessment for Alcohol - revised (CIWA-Ar) alcohol withdrawal scale. Phase 2 of the trial will examine the effect of Bioeffective A versus placebo on the outcome of conventional treatment of alcohol abstinence maintenance, during which all subjects will receive supportive counselling during attendance at a regular schedule of outpatient clinic reviews.
