Methohexital

5-Allyl-1-methyl-5-(1-methyl-2-pentynyl)-2,4,6(1H,3H,5H)-pyrimidinetrione

C14H18N2O3 (262.1317)

Methohexital is only found in individuals that have used or taken this drug. It is an intravenous anesthetic with a short duration of action that may be used for induction of anesthesia. [PubChem]Methohexital binds at a distinct binding site associated with a Cl^- ionopore at the GABA_A receptor, increasing the duration of time for which the Cl^- ionopore is open. The post-synaptic inhibitory effect of GABA in the thalamus is, therefore, prolonged.
