Heart Failure Drugs (Ch. 22, 24, 28) - Watch videos/study guide/blueprint. - TB - Dynamic quizzes Intro -Hypertension is a chronic condition characterized by elevated blood pressure, which increases the risk of cardiovascular and renal complications such as stroke, heart attack, heart failure, and kidney disease -Antihypertensive drugs are medications that lower blood pressure by acting on different targets in the cardiovascular system, such as receptors, enzymes, hormones, or ion channels -Cardiovascular medications are drugs that treat various disorders of the heart and blood vessels, such as angina, arrhythmias, heart failure, and hyperlipidemia -The choice of medication depends on the type and severity of the condition, the patient’s characteristics and preferences, and the potential benefits and risks of each drug Medications for hypertension management Adrenergic drugs: These drugs act on the sympathetic nervous system, which regulates blood pressure by controlling heart rate, cardiac output, vascular tone, and renin release. They include beta blockers, alpha blockers, centrally acting alpha 2 agonists, adrenergic neuron blockers, and alpha 1 and beta 1 blockers. Direct acting vasodilators: These drugs relax the smooth muscle of the blood vessels, causing them to widen and lower blood pressure. They include hydralazine, minoxidil, nitroprusside, and diazoxide. Angiotensin-converting enzyme (ACE) inhibitors: These drugs inhibit the enzyme that converts angiotensin I to angiotensin II, a potent vasoconstrictor and stimulator of aldosterone secretion. They include captopril, enalapril, lisinopril, ramipril, and others with the suffix -pril. Angiotensin II receptor blockers (ARBs): These drugs block the binding of angiotensin II to its receptors on blood vessels and adrenal glands, preventing its vasoconstrictive and aldosterone-stimulating effects. They include losartan, valsartan, candesartan, irbesartan, and others with the suffix -sartan. Calcium channel blockers: These drugs block the entry of calcium into cardiac and vascular smooth muscle cells, reducing their contractility and causing vasodilation. They include verapamil, diltiazem, nifedipine, amlodipine, felodipine, and others with the suffix -dipine. 1. Diuretics: These drugs increase the excretion of water and sodium by the kidneys, reducing blood volume and blood pressure.

Direct renin inhibitors: These drugs inhibit renin, an enzyme that catalyzes the first step in the renin-angiotensin-aldosterone system (RAAS), which regulates blood pressure and fluid balance. They include aliskiren.
