Chemical Structure

Chloral betaine is a complex formed between chloral hydrate and betaine. The chemical structure of chloral betaine allows it to release chloral hydrate slowly in the body, which contributes to its sedative effects. The molecular formula of chloral betaine is C₅H₁₁Cl₃O₂N.

Pharmacology

Chloral betaine acts as a central nervous system depressant. It works by enhancing the effects of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) in the brain, which leads to sedation and hypnosis. The drug is metabolized in the liver to produce chloral hydrate, which is the active form responsible for its pharmacological effects.
