How Does Ativan Affect GABA Signaling?

Lorazepam acts at benzodiazepine binding sites on gamma-aminobutyric acid type A receptors, increasing inhibitory GABA activity in the central nervous system. This action produces anxiolytic, sedative, muscle-relaxing, and anticonvulsant effects associated with benzodiazepines. Sedation and impaired coordination can also occur during treatment.

Treatment duration and dose are individualized according to symptoms, response, adverse reactions, and dependence risk.
