Final Answer:
Methyldopa activates alpha-2 adrenergic receptors after being converted to methylnorepinephrine by dopamine beta-hydroxylase
Step-by-step explanation:
Methyldopa activates alpha-2 adrenergic receptors after being converted to methylnorepinephrine by dopamine beta-hydroxylase. Methyldopa is a medication used to treat high blood pressure (hypertension). Once ingested, it is converted into methylnorepinephrine, which then stimulates alpha-2 adrenergic receptors in the central nervous system. This activation leads to a decrease in sympathetic nervous system activity, resulting in vasodilation and a subsequent reduction in blood pressure.
Methyldopa, an antihypertensive medication, is converted to methylnorepinephrine by dopamine beta-hydroxylase. Methylnorepinephrine activates alpha-2 adrenergic receptors in the central nervous system, leading to decreased sympathetic activity. This process results in vasodilation and helps lower blood pressure in the treatment of hypertension.
