Methyldopa functions as a centrally acting sympatholytic agent. It is believed to be converted in the brain to alpha-methylnorepinephrine, which then stimulates alpha-adrenergic receptors in the brainstem. This action reduces sympathetic outflow from the central nervous system, leading to a decrease in blood pressure [3].
