Secobarbital

Secobarbital, also known as secobarbitone in British English and by the brand name Seconal, is a short-acting psychoactive drug of the barbiturate class which produces powerful anxiolytic, hypnotic, muscle relaxant and amnesic effects. The combination drug Tuinal has a combination of secobarbital and amobarbital. Secobarbital is used medically as a hypnotic for the short-term treatment of insomnia and as an anticonvulsant in emergency situations, such as status epilepticus. Secobarbital works in a similar fashion to benzodiazepines, however, barbiturates bind to a different and distinct allosteric site on the GABAA receptor.
