Ativan, known by its generic name lorazepam, is a benzodiazepine medication commonly prescribed to manage anxiety disorders, panic attacks, and certain types of seizures. Its mechanism of action involves enhancing the effects of gamma-aminobutyric acid (GABA), a neurotransmitter that helps regulate brain activity by inhibiting nerve transmission. By increasing GABA activity, Ativan produces a calming effect on the central nervous system, which alleviates symptoms of anxiety and reduces the likelihood of seizures. Typically administered orally in tablet form, Ativan is known for its relatively fast onset of action, making it effective for addressing acute episodes of anxiety or panic.
