Barbiturate - Wikipedia, the free encyclopedia

Barbiturates are drugs that act as central nervous system depressants, and can therefore produce a wide spectrum of effects, from mild sedation to total.

Barbituric acid itself does not have any direct effect on the central nervous system and chemists have derived over 2,500 compounds from it that possess pharmacologically active qualities. The broad class of barbiturates is further broken down and classified according to speed of onset and duration of action. Ultrashort-acting barbiturates are commonly used for anesthesia because their extremely short duration of action allows for greater control. These properties allow doctors to rapidly put a patient "under" in emergency surgery situations.

Barbiturates are used to treat anxiety, insomnia, and seizure disorders. They are not, however, prescribed as often due to the availability of benzodiazepines and non-benzodiazepines. Barbiturates can be addictive and have strong withdrawal symptoms and rebound (exaggerated) effects on rapid eye movement (REM) sleep when they are abruptly stopped and can interfere with sleep.

It also is important to use the correct dose of barbiturates since a relatively small overdose may lead to coma or death.
