Ativan is a prescription medication classified as a benzodiazepine. It is commonly prescribed to manage anxiety disorders, insomnia, and certain types of seizures. Ativan works by enhancing the effects of a natural chemical in the body known as gamma-aminobutyric acid (GABA). By increasing GABA activity, Ativan helps to promote relaxation and reduce excessive brain activity, making it a key player in the treatment of anxiety-related conditions.
