Secobarbital is an intermediate- to short-acting (half-life 15-40 h) barbiturate drug that is used primarily as a hypnotic agent to treat insomnia. It is also used as a premedica-tion before surgery and for the emergency management of seizures. Secobarbital is an agonist at ► GABAa receptors thereby increasing inhibitory ► GABAergic transmission in the CNS. It binds to a distinct site upon the GABAA receptor ion channel complex increasing the duration of time for which the Cl_ channel is open. Secobarbital, like other barbiturate drugs, has a narrow therapeutic window, that is, a small difference between the minimum effective dose for sedation and maximum tolerated dose producing coma and death. Long-term use of this drug is contraindicated because of its ability to produce tolerance and dependence, and abrupt withdrawal from chronic treatment precipitates a life-threatening withdrawal syndrome. It is used illicitly for the purposes of getting high, to reduce anxiety, to counteract the effects of stimulant drugs, for example, cocaine, ecstasy, and in suicide.
