Ativan, also known by its generic name lorazepam, is a prescription medication that belongs to the class of drugs called benzodiazepines. It is primarily used to treat anxiety disorders, insomnia, and as a sedative before medical procedures.
Ativan works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA helps to regulate the activity of nerve cells, resulting in a calming and sedative effect. By increasing GABA activity, Ativan helps to reduce anxiety, promote relaxation, and induce sleep.
