Lorazepam is a high-potency short-to-intermediate-acting 3-hydroxy benzodiazepine drug.Lorazepam is used for the short-term treatment of anxiety, insomnia, acute seizures including status epilepticus and sedation of hospitalised patients, as well as sedation of aggressive patients.It is considered to be a short-acting drug which, similar to other benzodiazepines, exerts its therapeutic as well as adverse effects via its interaction at benzodiazepine binding sites, which are located on GABAA receptors in the central nervous system.Lorazepam is sometimes used for individuals receiving mechanical ventilation.It is sometimes used as an alternative to haloperidol when there is the need for rapid sedation of violent or agitated individuals,used in chemotherapy as an adjunct to antiemetics for treating anticipatory nausea and vomiting,as adjunct therapy for cyclic vomiting syndrome.
