Diazepam, a benzodiazepine with anticonvulsant, anxiolytic, sedative, muscle relaxant and amnesic properties. Its actions are mediated by enhancement of the activity of aminobutyric acid (GABA), a major inhibitory neurotransmitter in the brain. On oral administration, Diazepam is readily and completely absorbed from the gastrointestinal tract, peak plasma concentration occurring within about 30 to 90 minutes.
