Estazolam Brand Name– ProSom
What is Estazolam
Estazolam is an intermediate-acting oral benzodiazepine. It is used as a hypnotic for the short-term treatment of patients with insomnia. In comparison with flurazepam, estazolam has similar time to effect and efficacy, but a decreased incidence of side effects.
Estazolam does not have any active metabolites as compared to flurazepam or quazepam.
The FDA approved estazolam in December 1990.
In May 2007, Abbott announced a decision to discontinue the manufacture and distribution of the branded drug, ProSom, due to the availability of generic versions of estazolam and the prevalence of other insomnia therapies.
