Description

Lormetazepam (INN, or methyl-lorazepam, is a drug which is a short to intermediate acting 3-hydroxy benzodiazepine derivative. It possesses hypnotic, anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. Lormetazepam is considered a hypnotic benzodiazepine and is officially indicated for moderate to severe insomnia. Lormetazepam is a short-acting benzodiazepine and is sometimes used in patients who have difficulty in maintaining sleep or falling asleep. Hypnotics should only be used on a short-term basis or, in those with chronic insomnia, on an occasional basis.
