Debrisoquine Sulfate

Published: July 26, 2026Updated: August 27, 2026

Debrisoquine Sulfate is an antihypertensive agent that works by blocking alpha-adrenergic receptors, leading to vasodilation and reduced blood pressure. It was historically used in the management of moderate to severe hypertension, though its use has declined in favor of newer agents with more favorable side effect profiles. The medication requires careful dose titration and blood pressure monitoring during treatment initiation.

Primarily used for the treatment of hypertension (high blood pressure). May have been used in cases where other antihypertensive agents were not effective or tolerated. Not commonly prescribed in modern clinical practice.

Acts as a competitive antagonist at alpha-adrenergic receptors, preventing catecholamines (like norepinephrine) from causing vasoconstriction. This results in relaxation of vascular smooth muscle, vasodilation, and subsequently reduced blood pressure.

May cause orthostatic hypotension, dizziness, and reflex tachycardia. Requires careful titration to avoid excessive blood pressure reduction. Contraindicated in patients with pheochromocytoma. Drug interactions may occur with other antihypertensives and sympathomimetics. Use during pregnancy should be carefully considered against potential risks.
