pentobarbital wiki

pentobarbital wiki Pentobarbital(previously known as pentobarbitone in Britain and Australia) is a short-acting barbiturate typically used as a sedative, a preanesthetic, and to control convulsions in emergencies.[1] It can also be used for short-term treatment of insomnia but has been largely replaced by the benzodiazepine family of drugs.

In high doses, pentobarbital causes death by respiratory arrest. It is used for veterinary euthanasia and is used by some U.S. states and the U.S. federal government for executions of convicted criminals.[2] In some countries and states, it is also used for physician-assisted suicide.[3][4]

Pentobarbital was widely abused and sometimes known as “yellow jackets” due to the yellow capsule of the Nembutal brand. Pentobarbital in oral (pill) form is no longer commercially available.[2]

Pentobarbital, also known as pentobarbitone in British English and by the brand name Nembutal, is a short-acting psychoactive drug of the barbiturate class which produces powerful anxiolytic, hypnotic, muscle relaxant and amnesic effects. Pentobarbital is used medically as a hypnotic for the short-term treatment of insomnia and as an anticonvulsant in emergency situations. Pentobarbital is also used to put patients into medically induced comas. Pentobarbital works in a similar fashion to benzodiazepines, however barbiturates bind to a distinct allosteric site on the GABAA receptor.

Compared to other barbiturates such as phenobarbital, pentobarbital has a prompt onset of action, generally working within fifteen minutes of ingestion. Pentobarbital’s anxiolytic effects may last for up to 36 hours after the primary effects have worn off.

Pentobarbital, like most short-acting barbiturates, is deemed to be extremely addictive. The abrupt discontinuation of pentobarbital in dependent individuals may be life-threatening and lead to seizures and even death[2]. Pentobarbital drastically enhances the effects of other depressants such as alcohol, and concurrent use may lead to respiratory depression and possibly death.
