* 2013 ACC/AHA guidelines: high-intensity statin lowers cholesterol by >50%, moderate-intensity statin lowers cholesterol by 30-50%, low-intensity statin lowers cholesterol by <30%. All patients age 21-75 with any form of CVD, or LDL-C ≥ 190, should be given high-intensity statin unless they have clinical features that might predispose them to statin toxicity (i.e., serious co-morbidities such as renal or liver dz, hx statin intolerance, ALT >3xULN, drug interactions). Patients with CVD over 75 years old or unable to tolerate high-intensity statin should be on moderate-intensity statin. All patients with DM (age 40-75) with LDL-C 70-189, without known CVD, should receive moderate-intensity statin, or if 10-year risk by ASCVD risk calculator is > 7.5%, high-intensity statin. Patients age 40-75 without diabetes or CVD, but with LDL-C 70-189 and 10-year risk >7.5%, should consider a moderate-to-high intensity statin.
+ Atorvastatin 40-80mg considered high intensity. Avoid atorvastatin with glecaprevir/pibrentasvir (Mavyret) for HCV.
** 10 mg ezetimibe§ plus 10, 20, 40 or 80mg simvastatin. Vytorin not included in statin intensity charts
§ 2017 guidelines from ACC recommend considering non-statin therapies to achieve ≥50% LDL-C reduction (or LDL <70) for patients with clinical ASCVD who are already on maximally tolerated statin. First review adherence given estimates that ~50% of patients poorly adhere. Following that, combining ezetimibe, 10 mg/day, adds up to 25% additional LDL-C lowering. In patients who require more lowering, a PCSK9 inhibitor may be considered.
x FDA recommends that healthcare professionals should maintain patients on simvastatin 80mg only if they have been taking this dose for >12 months without evidence of muscle toxicity; do not start new patients on simvastatin 80mg or escalate to this dose.
x Do not exceed 10 mg simvastatin daily with diltiazem, verapamil.
x Do not exceed 20 mg simvastatin daily with amiodarone, amlodipine, ranolazine
x Avoid simvastatin with glecaprevir/pibrentasvir (Mavyret) for HCV.
