Lorazepam is a benzodiazepine with anxiolytic, sedative and hypnotic properties.
Lorazepam is almost completely absorbed from the gastrointestinal tract and peak serum levels are reached in 2 hours. It is metabolised by a simple one-step process to a pharmacologically inert glucuronide. There are no major active metabolites. The elimination half-life is about 12 hours and there is minimal risk of excessive accumulation.
Oesophageal dilation occurred in rats treated with lorazepam for more than one year at 6mg/kg/day.
