Detailed explanation-1: -Barbiturates are a kind of depressant or sedative drug. They are an old class of drug used to relax the body and help people sleep. These drugs were first developed in the late 19th century. Use of barbiturates as a recreational drug then became popular in the 1960s and 1970s, leading to abuse in some cases.
Detailed explanation-2: -The barbiturates have been used to treat insomnia (trouble in sleeping); but if they are used regularly (for example, every day) for insomnia, they are usually not effective for longer than 2 weeks. The barbiturates have also been used to relieve nervousness or restlessness during the daytime.
Detailed explanation-3: -All night sleep records taken during this period showed that the barbiturate shortened the delay to sleep, increased the total sleep period, lengthened the delay to rapid eye movement (R.E.M.) sleep, and depressed R.E.M. sleep. After five nights R.E.M. sleep returned to baseline values-that is, showed tolerance.
