Metaclazepam
Metaclazepam
Chemical compound
Metaclazepam[1] (marketed under the brand name Talis) is a drug which is a benzodiazepine derivative.[2][3] It is a relatively selective anxiolytic with less sedative or muscle relaxant properties than other benzodiazepines such as diazepam or bromazepam.[4] It has an active metabolite N-desmethylmetaclazepam, which is the main metabolite of metaclazepam.[5] There is no significant difference in metabolism between younger and older individuals.[6]
Metaclazepam is slightly more effective as an anxiolytic than bromazepam,[7] or diazepam,[8] with a 15 mg dose of metaclazepam equivalent to 4 mg of bromazepam.[9] Metaclazepam can interact with alcohol producing additive sedative-hypnotic effects.[6][10] Fatigue is a common side effect from metaclazepam at high doses.[11] Small amounts of metaclazepam as well as its metabolites enter into human breast milk.[12]
