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

[edit]

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]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
