Mechanism of action

Chloral hydrate is a prodrug that is metabolized to trichloroethanol, which acts as a positive allosteric modulator of GABA-A receptors. This enhancement of GABAergic inhibitory signaling depresses central nervous system activity, producing sedation and hypnotic effects. The drug has been used clinically for over a century as a short-acting sedative for insomnia and procedural sedation.
