Methyldopa (L-α-Methyl-3,4-dihydroxyphenylalanine; Aldomet, Aldoril, Dopamet, Dopegyt, thiab lwm yam) yog tus neeg sawv cev ntawm tus kabmob antihypertensive. Nws yog metabolized rau alpha-methylnorepinephrine nyob rau hauv lub hlwb, thiab qhov kev sib txuas no yog xav kom ua kom central alpha-2 adrenergic receptors (Gerber, 1990). Ua cov xaiv agonist rau α2 adrenergic receptors, psychoactive tshuaj yog siv los ua sympatholytic lossis antihypertensive. Nws qhov kev siv tam sim no feem ntau tsis ua raws li kev qhia txog kev nyab xeeb kev kawm ntawm cov neeg sawv cev. Txawm li cas los xij, nws txuas ntxiv kom muaj lub luag haujlwm tsis yooj yim los kho kev mob ntshav siab thiab kev mob ntshav tes taw (yav dhau los hu ua cev xeeb tub los ntshav (PIH)).
