Study Notes

Treatment of Hypertension

Diuretics: Help with the excretion of retained salt and water; commonly used examples include thiazide diuretics.
Angiotensin Converting Enzyme (ACE) Inhibitors: Medications such as Capoten block the action of the angiotensin converting enzyme, which helps in reducing blood pressure by preventing vasoconstriction and the secretion of aldosterone.
Angiotensin Receptor Blockers (ARBs): Examples include Losartan; these medications block the effects of angiotensin II, contributing to lower blood pressure.
Beta Blockers: Medications like Tenormin and Atenolol are utilized to treat mild hypertension by decreasing cardiac output, which lowers blood pressure.
Calcium Channel Blockers: Norvasc works by causing arteriolar dilation, thereby reducing blood pressure through relaxation of blood vessel walls.
Alpha 1 Blockers: Medications such as Cardura inhibit the adrenergic effects on blood vessel walls, causing vasodilation and are effective in rapidly reducing blood pressure during hypertensive crises.
Direct Vasodilators: Drugs like Minoxidil and Hydralazine directly relax blood vessels, which helps to lower blood pressure effectively.
