💊 Adverse Effects, Treatment, and Precautions
Peak plasma concentrations of estazolam are reached on average within 2 hours of oral doses. Estazolam is about 93% protein bound. Reported mean elimination half-lives have generally been in the range of 10 to 24 hours. Estazolam is extensively metabolised, mainly to 4-hydroxyestazolam and 1-oxoestazolam, which are considered inactive. These metabolites are excreted, either free or conjugated, in the urine with small amounts detected in the faeces. Only a small proportion of a dose is excreted as unchanged drug.
💊 Uses and Administration
Estazolam is a short-acting benzodiazepine with general properties similar to those of diazepam. It is given as a hypnotic in the short-term management of insomnia in usual oral doses of 1 to 2 mg at night. Small or debilitated elderly patients may be given an initial dose of 0.5 mg.
