Metabolism and urinary excretion of chlormethiazole in humans. 1975

R G Moore, and A V Robertson, and M P Smyth, and J Thomas, and J Vine

1. Chlormethiazole and five of its metabolites excreted in urine in man have been investigated by g.l.c.-mass spectrometry. 2. Four metabolites have been identified by comparison with authentic compounds as 5-acetyl-4-methylthiazole, 5-(1-hydroxyethyl)-4-methylthiazole, 5-(2-hydroxyethyl)-4-methylthiazole and 4-methyl-5-thiazoleacetic acid; 4-methyl-5-thiazoleacetaldehyde is proposed for the other metabolite. 3. The amounts of chlormethiazole and its identified metabolites excreted in urine have been quantitatively determined after a single oral dose in three healthy adults. Approximately 16% of the dose was excreted as chlormethiazole, 5-acetyl-4-methylthiazole, 5-(1-hydroxyethyx)-4-methylthiazole and 4-methyl-5-thiazoleacetic acid.

D002719 Chlormethiazole A sedative and anticonvulsant often used in the treatment of alcohol withdrawal. Chlormethiazole has also been proposed as a neuroprotective agent. The mechanism of its therapeutic activity is not entirely clear, but it does potentiate GAMMA-AMINOBUTYRIC ACID receptors response and it may also affect glycine receptors. Clomethiazole,Distraneurin
D002849 Chromatography, Gas Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
