Source-derived summary

Estazolam, sold under the brand name Prosom among others, is a tranquilizer medication of the triazolobenzodiazepine (TBZD) class, which are benzodiazepines (BZDs) fused with a triazole ring. It possesses anxiolytic, anticonvulsant, hypnotic, sedative and skeletal muscle relaxant properties. Estazolam is an intermediate-acting oral benzodiazepine. It is used for short-term treatment of insomnia.

It was patented in 1968 and came into medical use in 1975.

Medical uses

Estazolam is prescribed for the short-term treatment of certain sleep disorders. It is an effective hypnotic drug showing efficacy in increasing the time spent asleep as well as reducing awakenings during the night. Combination with non-pharmacological options for sleep management results in long-term improvements in sleep quality after discontinuation of short-term estazolam therapy. Estazolam is also sometimes used as a preoperative sleep aid. It was found to be superior to triazolam in side effect profile in preoperative patients in a trial.

Editorial analysis

Why this record matters

“Estazolam” is worth following because a concise public description often conceals a longer documentary argument. Here, Estazolam, benzodiazepine and derivative provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Nov 9, 2025. The linked authority identifier is Q3045264. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1968 and 1975.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
