Lorazepam, commonly known by its brand name Ativan, is a benzodiazepine medication primarily used for its anxiolytic (anxiety-reducing) properties. It is frequently prescribed for the short-term management of anxiety disorders, such as generalized anxiety disorder and panic disorder. By enhancing the effects of a neurotransmitter called gamma-aminobutyric acid (GABA), lorazepam helps to calm the nervous system, providing relief from symptoms such as excessive worry, agitation, and tension. It is often used in acute settings, such as during panic attacks or severe anxiety episodes, due to its rapid onset of action.

In addition to its use in anxiety management, lorazepam is also indicated for the treatment of insomnia, particularly when caused by anxiety or stress. Its sedative properties make it effective for helping patients achieve restful sleep. Lorazepam may be used as a premedication before surgical procedures or diagnostic tests to reduce anxiety and induce sedation. Furthermore, it plays a role in the treatment of alcohol withdrawal syndrome, alleviating symptoms like tremors and agitation. Despite its benefits, lorazepam should be used with caution, as it has the potential for dependence and withdrawal symptoms if used long-term.
