The most commonly used and most effective drugs for treating high LDL cholesterol are called statins. You doctor will choose one of these: lovastatin (Mevacor), pravastatin (Pravachol), simvastatin (Zocor), fluvastatin (Lescol), torvastatin (Lipitor), rosuvastatin (Crestor).
Other drugs that may be used include bile acid sequestering resins, cholesterol absorption inhibitors, fibrates, and nicotinic acid (niacin).
