Metabolite Identification
Common Namea-Methyldopa mono-O-sulfate
Descriptiona-Methyldopa mono-O-sulfate is a metabolite of methyldopa. Methyldopa (-α-Methyl-3,4-dihydroxyphenylalanine; Aldomet, Aldoril, Dopamet, Dopegyt, etc. ) is an alpha-adrenergic agonist (selective for α2-adrenergic receptors) psychoactive drug used as a sympatholytic or antihypertensive. Its use is now mostly deprecated following the introduction of alternative safer classes of agents. However, it continues to have a role in otherwise difficult to treat hypertension and gestational hypertension (also known as pregnancy-induced hypertension). (Wikipedia)
