RT Journal Article SR Electronic T1 THE METABOLIC FATE OF CHLORAL HYDRATE JF Journal of Pharmacology and Experimental Therapeutics JO J Pharmacol Exp Ther FD American Society for Pharmacology and Experimental Therapeutics SP 49 OP 58 VO 92 IS 1 A1 Thomas C. Butler YR 1948 UL http://jpet.aspetjournals.org/content/92/1/49.abstract AB Methods are described for the determination of trichloroethanol, chloral hydrate, and trichloroacetic acid when present together in plasma. When chloral hydrate is administered intravenously to dogs, the concentration of chloral hydrate in the plasma falls rapidly. Trichloroethanol and trichloroacetic acid appear very quickly in the plasma and reach such concentrations as to indicate that only a small part of the chloral hydrate is oxidized and that a high proportion, perhaps all, of the remainder is reduced to the alcohol. The removal of trichloroethanol from the plasma is relatively slow, and the concentrations reached are sufficient to account, in large part at least, for the depressant effects that follow the administration of chioral hydrate.
