Lorazepam is a type of benzodiazepine, which is an antianxiety medication, that is metabolized more rapidly than many other benzodiazepines. Lorazepam is mainly used for the short-term relief of symptoms of anxiety associated with depression, and it has been used to treat insomnia, nausea, and vomiting. Lorazepam was evaluated as an adjunct medication for the prevention of chemotherapy-induced nausea and vomiting (CINV) in patients with cancer, and it has been studied for its efficacy in the prevention of anticipatory CINV.
