Adverse Drug Reaction Classification System

Pharmaceutical Information
Drug Name Chloral hydrate
Drug ID BADD_D00428
Description A 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. It is no longer considered useful as an anti-anxiety medication.
Indications and Usage Mainly used as a hypnotic in the treatment of insomnia; however, it is only effective as a hypnotic for short-term use. May be used as a routine sedative preoperatively to decrease anxiety and cause sedation and/or sleep with respiration depression or cough reflex.
