For chronic ACS, what is the recommended atorvastatin dosing range?

• A. 10-20 mg daily
• B. 40-80 mg daily
• C. 5 mg daily
• D. 80-120 mg daily

Answer: (B)

In chronic ACS, the goal is to use high-intensity statin therapy to markedly lower LDL-C and reduce the risk of future events. For atorvastatin, the high-intensity dose range is 40–80 mg daily, which typically lowers LDL-C by about 50% or more and has proven benefits in secondary prevention after ACS. Lower doses like 10–20 mg or 5 mg are only moderate- or low-intensity and don’t achieve the same level of LDL reduction. Doses above the approved maximum (80 mg) aren’t standard practice and don’t provide proven extra benefit. So the recommended dosing range is 40–80 mg daily.
