Moxonidine
Moxonidine is a centrally-acting antihypertensive medication that works by stimulating imidazoline I1 receptors in the brain, reducing sympathetic nervous system activity and lowering blood pressure. It is primarily prescribed for the treatment of essential (primary) hypertension in patients who need additional blood pressure control.
Moxonidine is an antihypertensive that lowers blood pressure by reducing sympathetic nervous system activity through imidazoline receptor activation.

Moxonidine is used to treat essential (primary) hypertension, typically as a second-line agent when other antihypertensives are insufficient or as add-on therapy for patients requiring additional blood pressure control.
Moxonidine is an imidazoline I1 receptor agonist that acts on the rostral ventrolateral medulla in the brainstem. By stimulating these receptors, it reduces sympathetic outflow from the central nervous system, leading to decreased peripheral vascular resistance and lowered blood pressure.
Common side effects include dry mouth, drowsiness, and dizziness. Unlike clonidine, moxonidine has less affinity for alpha-2 adrenergic receptors, resulting in reduced sedation. Abrupt discontinuation should be avoided as it may cause rebound hypertension. Caution is needed in patients with severe coronary artery disease, moderate heart failure, or moderate-to-severe renal impairment.
