Which medication is NOT primarily used to treat hyperlipidemia?

• A. Simvastatin
• B. Losartan
• C. Gemfibrozil
• D. Cholestyramine

Answer: (B)

Understanding which medications directly target lipid levels helps explain why Losartan isn’t used to treat hyperlipidemia. Lipid-lowering drugs work by specific mechanisms: statins like Simvastatin inhibit HMG-CoA reductase, reducing hepatic cholesterol synthesis and lowering LDL. Fibrates such as Gemfibrozil activate PPAR-alpha, lowering triglycerides and often modestly increasing HDL. Bile acid sequestrants like Cholestyramine bind bile acids in the gut, prompting the liver to convert more cholesterol into bile acids, which lowers LDL. Losartan is an angiotensin II receptor blocker used for hypertension (and related conditions); it does not primarily affect lipid levels, so it isn’t a lipid-lowering agent.
