Medazepam is a drug that is a benzodiazepine derivative. It possesses anxiolytic, anticonvulsant, sedative, and skeletal muscle relaxant properties. It is known by the following brand names: Azepamid, Nobrium, Tranquirax (mixed with bevonium), Rudotel, Raporan, Ansilan and Mezapam.[2] Medazepam is a long-acting benzodiazepine drug. The half-life of medazepam is 36–200 hours.[3]
Pharmacology
Medazepam acts as a prodrug to nordazepam. Benzodiazepine drugs including medazepam increase the inhibitory processes in the cerebral cortex by allosteric modulation of the GABA receptor.[4] Benzodiazepines may also act via micromolar benzodiazepine-binding sites as Ca2+ channel blockers and significantly inhibited depolarization-sensitive calcium uptake in experiments with cell components from rat brains. This has been conjectured as a mechanism for high dose effects against seizures in a study.[5] It has major active benzodiazepine metabolites, which gives it a more prolonged therapeutic effect after administration.[6]
