Temazepam, sold under the brand name Restoril among others, is a medication of the benzodiazepine class which is generally used to treat severe or debilitating insomnia. [8] It is taken by mouth. [8] Temazepam is rapidly absorbed, and significant hypnotic and anxiolytic effects begin in less than 30 minutes and can last for up to eight hours.
The intravenous use of temazepam poses the greatest threat to those who misuse benzodiazepines. Simultaneous consumption of temazepam with heroin is a potential risk factor of overdose. An Australian study of non-fatal heroin overdoses noted that 26% of heroin users had consumed temazepam at the time of their overdose.
Improved reaction times were noted at 52 weeks in elderly patients free from benzodiazepines. This is an important function in the elderly, especially if they drive a car due to the increased risk of road traffic accidents in benzodiazepine users. [136] At the 24-week follow-up, 80% of people had successfully withdrawn from benzodiazepines.
Flutemazepam was initially first synthesized in 1965, [1] but was not further described until a team at Stabilimenti Chimici Farmaceutici Riuniti SpA in the mid-1970s. [2] [3] It is a short-acting (9–25 hr elimination half-life) fluorinated analogue of temazepam that has powerful hypnotic, sedative, amnesiac, anxiolytic, anticonvulsant and skeletal muscle relaxant properties.
[6] [21] The long-term effects of benzodiazepines may differ from the adverse effects seen after acute administration of benzodiazepines. [22] An analysis of cancer patients found that those who took tranquillisers or sleeping tablets had a substantially poorer quality of life on all measurements conducted, as well as a worse clinical picture ...
Due to these contraindications and the possibility of it causing severe adverse effects including seizures, adverse cardiac effects, and death, [50] [51] in the majority of cases there is no indication for the use of flumazenil in the management of benzodiazepine overdose as the risks in general outweigh any potential benefit of administration.
The central nervous system-depressant effects of benzodiazepines may make driving or operating machinery dangerous, and the elderly are more prone to these adverse effects. High single doses or repeated low doses have been reported to produce hypotonia , poor sucking, and hypothermia in the neonate , and irregularities in the fetal heart.
In one clinical trial with patients who had prior experience with older hypnotics temazepam and nitrazepam, most preferred lormetazepam due to less heavy sedation, amnesia, and residual effects. [8] Some side effects, including drowsiness, amnesia, and respiratory depression, are increased when lormetazepam is combined with other drugs with ...
