Lorazepam, commonly known by its brand name Ativan, belongs to a class of medications called benzodiazepines. It works by enhancing the effects of a neurotransmitter in the brain called gamma-aminobutyric acid (GABA), which leads to a calming effect. Prescribed for various conditions, lorazepam can help with anxiety relief, sleep disorders, and even seizure management. However, due to its potential for dependence and side effects, it must be taken under the supervision of a healthcare professional.
