Ativan is a brand name for the drug lorazepam, which belongs to a class of medications called benzodiazepines. Ativan is primarily used for the treatment of anxiety disorders and for the short-term relief of symptoms of anxiety. Here are the main uses of Ativan:

1. Anxiety Disorders: Ativan is commonly prescribed to manage symptoms of generalized anxiety disorder (GAD), panic disorder, and social anxiety disorder. It works by enhancing the effects of gamma-aminobutyric acid (GABA), a neurotransmitter that helps calm the brain and reduce feelings of anxiety.

2. Short-term Relief of Anxiety Symptoms: Ativan is often used on a short-term basis to provide immediate relief from acute anxiety symptoms, such as panic attacks or severe anxiety episodes.

3. Preoperative Sedation: Ativan may be used as a preoperative medication to help calm anxious patients before surgical procedures. It can help reduce anxiety and promote relaxation in preparation for surgery.

4. Seizure Disorders: Ativan is sometimes used as an adjunctive therapy in the treatment of certain types of seizures, such as status epilepticus (prolonged seizures) or as a temporary measure to control acute seizures until long-term antiepileptic medications take effect.
