2.5 lorazepam

Lorazepam is a medication that belongs to the benzodiazepine class of drugs. It is commonly prescribed to treat anxiety disorders, insomnia, and certain types of seizures. Lorazepam works by enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA is a neurotransmitter that has a calming effect on the brain, and by increasing its activity, lorazepam helps to reduce anxiety and promote relaxation.
