Thiopental sodium. IV general anaesthetic Increases the duration of GABA dependent Cl channel opening in Induction of anaesthesia Acute porphyria Myotonic dystrophy Severe CV disease Thiopental drug class IV general anaesthetic Thiopental mechanism Increases the duration of GABA dependent Cl channel opening in. sodium pentothal drug class Thiopental Sodium is the sodium salt form of thiopental, an ultrashortacting barbituric acid derivative, with anesthetic activity. Thiopental binds to the chloride ionophore site of the gammaaminobutyric acid ( GABA )A chloride ionophore receptor complex, thereby enhancing the inhibitory actions of GABA
Gradually taper infusion or convert to an oral barbiturate (e. g. , phenobarbital) after prolonged therapy to avoid symptoms of withdrawal. Pentobarbital therapy is an alternative option for sedation in those who fail standard therapy; significant complications including hypotension, oversedation, neurologic sequelae, and drug reaction limit its use. sodium pentothal drug class
The drug is mostly used in interrogation, but it can also be used for helping people relax before you receive general anesthesia with an inhaled medication. But still the most common use for sodium pentothal is the use as an interrogation drug. Sodium thiopental is a rapidonset shortacting barbiturate general anaesthetic. Thiopental is an ultrashort acting barbiturate and is most commonly used in the induction phase of general anesthesia. Following intravenous injection the drug rapidly reaches the Thiopental, and the barbiturate class of drugs, decrease neuronal activity and therefore decrease the production of osmotically active metabolites which in turn decreases swelling. Patients with significant swelling have improved outcomes following the induction of coma. sodium pentothal drug class However, when thiopental is given by prolonged infusion, hepatic enzyme saturation changes its metabolism from a firstorder to a zeroorder process, which together with a very large volume of distribution, causes accumulation. Accumulation of thiopental may result in extended elimination times and very delayed recovery. Thiopental (Pentothal), however, is an effective anesthetic induction drug although other agents, such as propofol (Diprivan) are increasingly commonly used. References Katzung, B. G.
