[Effect of psychotropic drugs on sleep disorders in rats during alcohol withdrawal].

The effects of sodium hydroxybutyrate (100 mg/kg); phenazepam (1 mg/kg), apomorphine (0.1 mg/kg and haloperidol (1 mg/kg) on the electrophysiological sleep pattern were studied in rats during 7-day alcohol withdrawal after its voluntary consumption for 13 months. It was shown that alcohol withdrawal led to profound disorders in the sleep-waking cycle. Sodium hydroxybutyrate prevented these disturbances and brought sleep to normal. Phenazepam exerted a powerful sedative and hypnotic effects but did not improve the balance of sleep phases. Apomorphine displayed a tendency to sleep normalization. However, this effect was short-term. Haloperidol did not eliminate abstinence manifestations in the sleep pattern.
