Benzodiazepines are a class of psychoactive drugs known for their sedative, anxiolytic, muscle relaxant, and anticonvulsant properties. Commonly prescribed medications in this category include diazepam (Valium), lorazepam (Ativan), and alprazolam (Xanax). These drugs act primarily on the central nervous system by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA).
