A patient who has hyperlipidemia has been taking atorvastatin (Lipitor) 60 mg daily for 6 months. The patient's initial lipid profile showed LDL of 180 mg/dL, HDL of 45 mg/dL, and triglycerides of 160 mg/dL
The primary care NP orders a lipid profile today that shows LDL of 105 mg/dL, HDL of 50 mg/dL, and triglycerides of 120 mg/dL. The patient reports muscle pain and weakness. The NP should: a. order liver function tests (LFTs).
b. order a creatine kinase-MM (CK-MM) level.
c. change atorvastatin to twice-daily dosing.
d. add gemfibrozil (Lopid) to the patient's medication regimen.
B
Hepatotoxicity and muscle toxicity are the two primary adverse effects of greatest concern with statin use. Patients who report muscle discomfort or weakness should have a CK-MM level drawn. LFTs are indicated with signs of hepatotoxicity. It is not correct to change the dosing schedule. Gemfibrozil is not indicated.
