Brotizolam (marketed under brand name Lendormin) is a drug which is thienobenzodiazepine (a benzodiazepine derivative). It possesses anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties, and is considered to be similar in effect to short-acting benzodiazepines such as triazolam. It is used in the short term treatment of insomnia although due to its short half life it is considered to have relatively high abuse potential and so would not be a first-line treatment. Brotizolam is a potent drug with a dosage of between 0.5 and 1.5 milligrams, but is rapidly eliminated with an average half life of 4.4 hours (range 3.6 - 7.9 hours).
Brotizolam is not approved for sale in the UK, United States or Canada.
Brotizolam induces impairment of motor function and has hypnotic properties. Brotizolam increases the slow wave light sleep (SWLS) in a dose-dependent manner whilst suppressing deep sleep stages. Less time is spent in stages 3 and 4 which are the deep sleep stages when benzodiazepines such as brotizolam are used. Benzodiazepines are therefore not good hypnotics in the treatment of insomnia. The suppression of deep sleep stages by benzodiazepines may be especially problematic to the elderly as they naturally spend less time in the deep sleep stage.
Insomnia. Brotizolam is prescribed for the short term treatment, 2 - 4 weeks only of severe insomnia. Insomnia can be described as a difficulty falling asleep, frequent awakening, early awakenings or a combination of each. Brotizolam is a short-intermediate acting benzodiazepine and is sometimes used in patients who have difficulty in maintaining sleep or getting to sleep. Hypnotics should only be used on a short term basis or in those with chronic insomnia on an occasional basis.
