Answer to Question 1

D
Creatinine kinase levels are the best laboratory indicator of myopathy and/or rhabdomyolysis, which may lead to renal failure. As with the statins, gemfibrozil and other fibrates can cause myopathy. Fibrates must be used with caution in patients taking statins. Concurrent use of gem-fibrozil and rosuvastatin does not cause tendon tenderness or a lupus-like syndrome. Liver func-tion levels should be determined at the start of statin therapy and every 6 months thereafter in patients who do not have liver disease.

Answer to Question 2

B
Reductions in LDL cholesterol are significant within 2 weeks and maximal within 4 to 6 weeks. It does not take 6 months to see a change. The blood level of LDL cholesterol is not reduced immediately upon starting the drug; a reduction is seen within 2 weeks. Blood cholesterol is af-fected, specifically LDL cholesterol, not triglycerides.
