Lorazepam

Brand Names: Ativan, Loreev XR, Temesta.

Definition: Lorazepam is a medication in the benzodiazepine class used to treat anxiety disorders, insomnia, and acute seizures. It works by enhancing the effects of GABA, a natural inhibitory neurotransmitter in the brain, which produces a calming effect on the central nervous system. Due to its sedative and muscle-relaxant properties, it is also frequently used as a premedication before surgery or to manage symptoms of alcohol withdrawal.
