Ativan

Overview

What is Ativan? 

Ativan is a brand of prescription medication known for its anxiolytic (anxiety-relieving), sedative, and anticonvulsant properties. Its active ingredient is lorazepam, which is a benzodiazepine (a class of “depressant” or “downer” drugs). 

Lorazepam works by enhancing the effects of γ-Aminobutyric acid 

 (GABA), a major inhibitory neurotransmitter in the brain that induces calmness.
