Antitussives are for cough - not hypertension. Beta - Adrenergic Blockers/Calcium Channel Blockers reduce blood pressure by affecting heart and blood vessels. Peripheral Vasodilators widen blood vessels to lower blood pressure. Procainamide is mainly for arrhythmias, not hypertension. Thiazide Diuretics reduce fluid volume to lower blood pressure.
