Used primarily in the management of hypertension, especially in acute settings. It helps lower blood pressure by acting as an alpha-1 adrenergic receptor blocker and a 5-HT1A receptor agonist. Commonly administered intravenously in emergency or perioperative situations where rapid but controlled reduction of blood pressure is needed. Also used in some cases for the treatment of severe hypertension in intensive care units. Its dual mechanism provides effective vasodilation with relatively fewer side effects like reflex tachycardia.
