Chloral betaine
Chloral betaine (USAN, BAN) (brand names Beta-Chlor, Somilan), also known as cloral betaine (INN), is a sedative-hypnotic drug. It was introduced by Mead Johnson in the United States in 1963. It is a betaine complex with chloral hydrate, which acts as an extended-acting formulation of chloral hydrate which is then metabolized into trichloroethanol, which is responsible for most or all of its effects.
