Study Notes
Cardiovascular System Medications
Beta-Blockers
- Slow down heart rate; monitor heart rate during treatment.
Angiotensin-Converting Enzyme (ACE) Inhibitors
- Used for hypertension, heart failure, myocardial infarction (MI), and diabetic nephropathy.
- Mechanism: Blocks formation of angiotensin II, leading to vasodilation and increased potassium levels.
- Adverse effects: Possible angioedema, hyperkalemia; generally well tolerated with some serious allergic responses.
- Examples: captopril, lisinopril, enalapril, fosinopril.
Angiotensin II Receptor Blockers (ARBs)
- Indicated for hypertension, heart failure, MI, and diabetic nephropathy.
- Function: Blocks angiotensin II receptors promoting vasodilation and increased potassium.
- Side effects: Headaches, dizziness, GI complaints, and respiratory symptoms.
- Examples: losartan, irbesartan, valsartan.
Aldosterone Antagonists
- Used in heart failure post-MI and hypertension.
- Mechanism: Blocks aldosterone receptors, increasing Na and water excretion and reducing blood volume.
- Examples: eplerenone, spironolactone.
Calcium Channel Blockers (CCBs)
- Indications include hypertension, angina, and cardiac dysrhythmias.
- Mechanism: Inhibits calcium entry into smooth muscle and myocardium, leading to vasodilation and reduced contraction force.
- Adverse effects: Bradycardia, hypotension, and peripheral edema.
- Examples:
- Selective for blood vessels: nifedipine, amlodipine.
- Non-selective: verapamil, diltiazem.
Alpha-1 Adrenergic Blockers
- Used for hypertension.
- Mechanism: Blocks alpha-1 receptors in arterioles, causing vasodilation.
- Adverse effects include headache, weakness, nausea, and dizziness.
- Examples: doxazosin, prazosin.
Centrally Acting Alpha-2 Agonists
- Indicated for hypertension.
- Mechanism: Stimulates alpha-2 receptors in the brain, leading to relaxation of arteries and reduced cardiac output.
- Example: clonidine.
Cardioselective Beta-1 Blockers
- Treats hypertension, angina, heart failure, tachydysrhythmias, and MI.
- Functions: Decreases contraction force, heart rate, and conduction speed via AV node.
- Also, reduces renin release, leading to vasodilation.
- Adverse effects: Can impact exercise tolerance and cause fluctuations in blood sugar.
- Examples: metoprolol, atenolol.
Non-selective Beta Blockers
- Indications are similar to cardioselective plus cardiac dysrhythmias.
- Mechanism: Blocks beta-1 and beta-2 receptors in myocardium, kidneys, and lungs.
- Side effects include GI issues and respiratory effects.
- Examples: propranolol, carvedilol, labetalol.
Vasodilators
- Primarily used for hypertensive emergencies.
- Mechanism: Centrally acting, provides a rapid reduction in blood pressure and decreases preload and afterload.
- Caveats: Risk of cyanide toxicity.
- Example: nitroprusside.
Cardiac Glycosides
- Indicated for heart failure and atrial fibrillation.
- Mechanism: Inhibits Na/K/ATPase, increasing intracellular calcium, enhancing contraction force.
- Side effects: Headaches, visual changes, gastrointestinal issues, and potential for arrhythmias.
- Example: digoxin.
Diuretics
- Used primarily for hypertension.
- Variants include thiazide and loop diuretics such as Lasix.
Antilipemic Agents
- HMG-CoA Reductase Inhibitors (Statins): Reduce cholesterol by blocking hepatic enzymes, decreasing LDL and VLDL; may cause GI issues and hepatotoxicity.
- Example: atorvastatin.
- Cholesterol Absorption Inhibitors: Reduce cholesterol absorption from the intestine; mild side effects like abdominal pain and risk of hepatitis.
- Example: ezetimibe.
- Bile-Acid Sequestrants: Bind bile acids, promoting cholesterol excretion; side effects include headache and fatigue.
- Example: colesevelam.
