title: Double-blind evaluation of temazepam, flurazepam, and placebo in geriatric insomniacs.
abstract: The efficacy and safety of temazepam (30 mg) were compared with the efficacy and safety of flurazepam hydrochloride (30 mg) and placebo in a four-day, double-blind study in 75 geriatric convalescent-home patients with insomnia. The efficacy and safety profiles of the two active drugs were similar. Patients treated with temazepam, however, reported significantly less drug hangover both on awakening and during the entire day after each night of treatment than did patients receiving flurazepam or placebo. The difference between temazepam and flurazepam was probably due to the drugs' markedly different half-lives, temazepam's mean half-life being ten hours compared with 65.5 hours for the active metabolite of flurazepam. It is well recognized that the elderly may be especially sensitive to the adverse effects associated with the accumulation of the long-acting metabolite of flurazepam. Since temazepam has no active metabolites and minimal accumulation, it is a particularly appropriate hypnotic for use in geriatric patients.
