Brotizolam〔DE Patent 2445430〕 (marketed under brand name Lendormin) is a sedative-hypnotic thienodiazepine drug which is a benzodiazepine analog. It possesses anxiolytic, anticonvulsant, hypnotic, 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 severe or debilitating insomnia. Brotizolam is an extremely potent drug and has shown anti-anxiety activity at doses as low as 0.08 to 0.1 milligrams, but the usual hypnotic dose of brotizolam is 0.125 to 0.25 milligrams, and it is rapidly eliminated with an average half-life of 4.4 hours (range 3.6 - 7.9 hours).〔 The drug was developed by a team led by T Nishiyama while working for Takeda Chemical Industries in 1976 in Japan. Brotizolam is not approved for sale in the UK, United States or Canada. It is approved for sale in the Netherlands, Germany, Spain, Belgium, Luxembourg, Austria, Portugal, Israel, Italy, Taiwan and Japan. ==Indications== Insomnia. Brotizolam is prescribed for the short-term treatment, 2–4 weeks only of severe or debilitating insomnia. Insomnia can be described as a difficulty falling asleep, frequent awakening, early awakenings or a combination of each. Brotizolam is a short-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. Premedication. Brotizolam, in a dose of 0.25 mg can be used as a premedication prior to surgery, this dose was found to be comparable in efficacy to 2 mg flunitrazepam as a premedicant prior to surgery. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「brotizolam」の詳細全文を読む スポンサード リンク
