NCIt definition : A synthetic monohydrate of chloral with sedative, hypnotic, and anticonvulsive properties.
Chloral hydrate is converted to the active compound trichloroethanol by hepatic alcohol
dehydrogenase. The agent interacts with various neurotransmitter-operated ion channels,
thereby enhancing gamma-aminobutyric acid (GABA)-A receptor mediated chloride currents
and inhibiting amino acid receptor-activated ion currents. In addition, chloral hydrate
enhances the agonistic effects of glycine receptors, inhibits AMPA-induced calcium
influx in cortical neurons, and facilitates 5-HT 3 receptor-mediated currents in ganglionic
neurons. Overall, this results in a depressive effect on the central nervous system.;
