Methyldopa is a centrally acting antihypertensive agent. It is metabolized to alpha-methylnorepinephrine in the brain, and this compound activates central alpha-2 adrenergic receptors. Being a selective agonist for α2 adrenergic receptors, psychoactive drug is used as a sympatholytic or antihypertensive.
