| umls-concept:C0008161 | skos:definition | MSH: A hypnotic and sedative used in the treatment of INSOMNIA.,CSP: hypnotic and sedative used in the treatment of insomnia; the safety margin is too narrow for chloral hydrate to be used as a general anesthetic in humans, but it is commonly used for that purpose in animal experiments; chemical formula CCL3CH(OH)2.,NCI: 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. | lld:umls |
