The treatment of tranquilizer dependence by propranolol

Forty four subjects were treated for benzodiazepine dependence. The withdrawal programme lasted for 10 weeks and included regular group support sessions. Patients were also treated with either propranolol, placebo or "no pill" under double blind conditions. Twenty three patients complied with the full treatment regimen and completed the trial. The outcome of treatment was moderately successful, with 8 out of the 23 patients stopping their tranquilizers and a further 11 achieving a reduction of 50% or more of their original benzodiazepine dose. Tranquilizer dependence is a difficult condition to treat, but preliminary results suggest that propranolol is helpful in reducing the symptoms of benzodiazepine withdrawal.
