A comparison of the efficacy and tolerability of clobazam and chlordiazepoxide in the treatment of acute withdrawal from alcohol in patients with primary alcoholism.

Forty patients with primary chronic alcoholism took part in a randomized, double-blind, comparative group study of clobazam and chlordiazepoxide in the treatment of acute alcohol withdrawal. Assessments were carried out during an initial in-patient week followed by a week of out-patient assessments. Both benzodiazepines were shown to be highly effective when compared with baseline measurements. However, the Hamilton Anxiety Rating Scale showed clobazam to be more effective than chlordiazepoxide at both 7 days (p = 0.03) and 14 days (p less than 0.05). The clobazam group showed significant improvements compared with baseline for all four factors of the Leeds Sleep Evaluation Questionnaire, whereas the chlordiazepoxide group showed a significant improvement in only one factor. At the end of the in-patient week, clobazam showed a significant improvement (p less than 0.01) compared to chlordiazepoxide for the Linear Analogue Rating Scale of anxiety/tension. The 1,5 benzodiazepine clobazam has been shown to be a valuable addition to currently available regimens when used alone in the treatment of acute alcohol withdrawal, especially during the initial period where anxiety and insomnia related symptoms are at their peak.
