Treatment of hypertension (chronic and emergency settings), hypertensive crises, and pregnancy-induced hypertension. Often used when multiple blood pressure medications are needed or when rapid blood pressure reduction is required.
Blocks both alpha-1 adrenergic receptors (causing vasodilation) and beta-adrenergic receptors (reducing heart rate and cardiac output). This dual action provides more comprehensive blood pressure reduction compared to beta-blockers alone.
May cause dizziness, orthostatic hypotension, or bradycardia. Contraindicated in patients with asthma, severe bradycardia, or heart block. Should not be discontinued abruptly. Oral and IV doses differ significantly; IV administration requires close monitoring.
