Metaclazepam (Talis) is a drug which is a benzodiazepine derivative. It is a relatively selective anxiolytic with less sedative or muscle relaxant properties than other benzodiazepines such as diazepam or bromazepam.[1]

Metaclazepam is slightly more effective as an anxiolytic than bromazepam,[2] or diazepam,[3] with a 15mg dose of metaclazepam equivalent to 4mg of bromazepam.[4]
