Pharmacokinetic properties of benzodiazepine hypnotics. 1983

D J Greenblatt, and D R Abernethy, and M Divoll, and J S Harmatz, and R I Shader

The kinetic properties of three benzodiazepine hypnotics are reviewed. Flurazepam serves as a precursor for at least two rapidly appearing and rapidly cleared metabolites that may contribute to sleep induction and are nonaccumulating. The final metabolite of flurazepam (N-desalkylflurazepam), however, has a long half-life and accumulates during repeated dosage. Temazepam has a relatively slow rate of absorption and an intermediate half-life in the range of 10 to 20 hours. Triazolam has an intermediate rate of absorption; due to its ultrashort half-life (1.5 to 5 hours), triazolam is a non-accumulating hypnotic. Taken together with sleep laboratory studies and clinical trials, knowledge of the kinetic profile of benzodiazepine hypnotics can assist in evaluating their clinical benefits and disadvantages.
