Zolpidem: distinct from triazolam?
1Department of Pharmacy, Methodist Hospitals of Memphis-Central, TN 38104, USA.
Objective:
To review the literature that compares zolpidem with triazolam, with an emphasis on efficacy and safety in humans.
Data Sources:
Information was retrieved from a MEDLINE search (1983-1996) of the English-language literature using the terms triazolam and zolpidem.
Study Selection:
Reports of clinical trials comparing the safety and efficacy of zolpidem and triazolam were included in this review.
Data Extraction:
Data were evaluated according to study design, efficacy, and adverse effects. Pertinent information was selected and the data synthesized into a review format.
Data Synthesis:
Zolpidem and triazolam have similar pharmacokinetic and pharmacodynamic effects in humans. Clinical trials have shown that usually recommended, equipotent dosages of zolpidem and triazolam do not differ with respect to pharmacokinetics, efficacy, tolerability, residual effects, memory impairment, rebound insomnia, abuse potential, or other adverse effects.
Conclusions:
Zolpidem offers no distinct therapeutic advantage over triazolam for the treatment of insomnia.
