title: [Antiabstinent action of fenibut and baclofen on a model of abstinence induced by the benzodiazepine receptor antagonist CGS 8216 in rats receiving diazepam].
abstract: Benzodiazepine receptor antagonist CGS 8216 (2.5 mg/kg) induced clear-cut signs of abstinence lasting 1-1.5 hours in rats after discontinuation of diazepam treatment (10-20 mg/kg/day, 20 days). Diazepam (10-20 mg/kg) and GABAB-receptor agonists: phenibut (10-100 mg/kg) and baclofen (1.25-5.0 mg/kg) abolished the signs of abstinence. Conversely, GABAB-receptor agonist THIP enhanced the signs of abstinence. It is suggested that anti-abstinence effect of phenibut and baclofen may reflect their tranquilizing activity.
