It seems like you're referring to "Ativan," which is a brand name for the medication lorazepam. Ativan belongs to the benzodiazepine class of drugs and is primarily used to treat anxiety disorders and occasionally used for other conditions. Here are some key points about Ativan:

Purpose: Ativan is prescribed to relieve symptoms of anxiety disorders, including generalized anxiety disorder (GAD), as well as for anxiety associated with depression and other medical conditions.

Mechanism: It works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA helps to reduce the excessive brain activity that can lead to anxiety.
