ACC/AHA cholesterol management guideline states that nonstatin drugs (e.g., bile acid sequestrants) do not provide acceptable atherosclerotic cardiovascular disease (ASCVD) risk reduction benefits compared to their potential for adverse effects in the routine prevention of ASCVD. May be useful as adjuncts to statin therapy in high-risk patients (e.g., patients with ASCVD, LDL-cholesterol concentrations ≥190 mg/dL, or diabetes mellitus) who have a less-than-anticipated response to statins, are unable to tolerate even a less-than-recommended intensity of a statin, or are completely intolerant to statin therapy. Select nonstatin drug based on favorable benefit-risk ratio (i.e., demonstrated benefit of ASCVD risk reduction outweighs risks of adverse effects and drug interactions) and patient preferences.
