Methyldopa is an antihypertensive medication used to treat high blood pressure. There are several synonyms for methyldopa, including alpha-methyldopamine, Aldomet, dopamethyl, and L-α-methyl-3,4-dihydroxyphenylalanine. Methyldopa works by reducing the activity of the sympathetic nervous system, which helps to dilate blood vessels and reduce blood pressure. It is also used to treat gestational hypertension, a type of high blood pressure that occurs during pregnancy. Methyldopa is available as tablets or capsules and may be prescribed alone or in combination with other medications. As with all medications, it is important to take methyldopa as directed by a healthcare provider to achieve the best possible results.
