Pharmacology
Benzodiazepine drugs including medazepam increase the inhibitory processes in the cerebral cortex by allosteric modulation of the GABA receptor. 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. It has major active benzodiazepine metabolites, which gives it a more prolonged therapeutic effects after administration.
