Lorazepam is a medication belonging to the benzodiazepine class, commonly prescribed to treat anxiety disorders, insomnia, and seizures. It works by enhancing the effects of a neurotransmitter called GABA, which helps to calm the brain and nervous system. This medication is usually taken orally, but it can also be administered intravenously in medical settings. While effective, Lorazepam can lead to dependence if used for extended periods, so it is important to follow a doctor's guidance regarding dosage and duration of use.
