Methohexital or methohexitone (marketed under the brand names Brevital and Brietal) is a barbiturate derivative. It is classified as short-acting, and has a rapid onset of action. It is similar in its effects to sodium thiopental, a drug it competed with in the market for anesthetics.

Methohexital or methohexitone (marketed under the brand names Brevital and Brietal) is a barbiturate derivative. It is classified as short-acting, and has a rapid onset of action. It is similar in its effects to sodium thiopental, a drug it competed with in the market for anesthetics.
==Pharmacology== Methohexital binds to a distinct site which is associated with Cl− ionophores at GABAA receptors. This increases the length of time which the Cl− ionopores are open, causing an inhibitory effect.
