Which medication is most appropriate for long-term management of cholesterol in patients with coronary artery disease?

Choice A rationale Furosemide is a loop diuretic used to treat edema and hypertension. It primarily works by increasing the excretion of salt and water from the body and does not have a direct role in the long-term management of cholesterol levels in patients with coronary artery disease. Choice B rationale Statins are the cornerstone of long-term cholesterol management in patients with coronary artery disease. They work by inhibiting HMG-CoA reductase, an enzyme essential for cholesterol synthesis in the liver, thereby lowering LDL ("bad") cholesterol and reducing the risk of cardiovascular events. Choice C rationale Nifedipine is a calcium channel blocker used to treat hypertension and angina. While it can improve coronary blood flow, it does not directly affect cholesterol levels and is not considered a primary medication for the long-term management of hyperlipidemia. Choice D rationale Clopidogrel is an antiplatelet medication that prevents blood clots. Its role is to reduce the risk of thrombosis in patients with coronary artery disease, but it has no effect on cholesterol metabolism and is not used for the management of lipid levels.
