What is the recommended dosage of statin (HMG-CoA reductase inhibitor) for a male in his early 60s with elevated Low-Density Lipoprotein (LDL) cholesterol?

Statin Dosing for a Male in His Early 60s with Elevated LDL

For a male in his early 60s with elevated LDL cholesterol, initiate moderate-intensity statin therapy with either atorvastatin 10-20 mg or rosuvastatin 5-10 mg once daily, targeting a 30-49% reduction in LDL cholesterol from baseline. 1

Risk Stratification Determines Intensity

The appropriate statin intensity depends critically on this patient's cardiovascular risk profile:

Moderate-Intensity Therapy (Standard Approach)

• For patients aged 40-75 years without established atherosclerotic cardiovascular disease (ASCVD), moderate-intensity statin therapy is the recommended starting point. 1
• Moderate-intensity options include:
  • Atorvastatin 10-20 mg daily 1, 2
  • Rosuvastatin 5-10 mg daily 1, 3
  • Simvastatin 20-40 mg daily 1
  • Pravastatin 40-80 mg daily 1
• This approach targets a 30-49% reduction in LDL cholesterol from baseline. 1, 4

High-Intensity Therapy (For Higher Risk Patients)

If this patient has additional ASCVD risk factors (family history of CVD, hypertension, smoking, or albuminuria), escalate to high-intensity statin therapy targeting ≥50% LDL reduction and an LDL goal of <70 mg/dL. 1

High-intensity options include:

• Atorvastatin 40-80 mg daily 1, 2
• Rosuvastatin 20-40 mg daily 1, 3

Established ASCVD (Secondary Prevention)

For patients with known coronary disease, stroke, or peripheral arterial disease, high-intensity statin therapy is mandatory, targeting an LDL cholesterol <55 mg/dL. 1

Specific Drug Selection Considerations

Rosuvastatin vs Atorvastatin

While both are effective, rosuvastatin demonstrates superior LDL-lowering efficacy milligram-for-milligram compared to atorvastatin. 5, 6

• Rosuvastatin 10 mg achieves approximately 52% LDL reduction 7
• Atorvastatin 10 mg achieves approximately 37-39% LDL reduction 6
• Rosuvastatin 10 mg is roughly equivalent to atorvastatin 20 mg in LDL-lowering potency. 6, 8

Practical Starting Recommendations

For most patients in this age group, start with atorvastatin 10-20 mg or rosuvastatin 5-10 mg, as these provide moderate-intensity therapy with excellent tolerability. 1, 4

Diabetes Considerations

If this patient has diabetes mellitus, the recommendations are more aggressive:

• All diabetic patients aged 40-75 years should receive at least moderate-intensity statin therapy regardless of baseline LDL level. 1
• Diabetic patients with additional ASCVD risk factors should receive high-intensity therapy targeting LDL <70 mg/dL. 1
• The target for diabetic patients with established ASCVD is LDL <55 mg/dL. 1

Monitoring and Titration

Assess LDL cholesterol 4-12 weeks after initiating therapy to determine if the target reduction has been achieved. 1, 3, 2

• If inadequate response on moderate-intensity therapy, increase to high-intensity statin. 1, 4
• If LDL remains ≥70 mg/dL on maximally tolerated statin in high-risk patients, add ezetimibe. 1
• Once at goal, monitor lipids annually. 1, 4

Critical Pitfalls to Avoid

Do not use LDL cholesterol levels alone to decide whether to initiate therapy in this age group—the decision is based on age and risk factors, not just the LDL number. 1

For patients who develop side effects, reduce to the maximum tolerated dose rather than discontinuing therapy entirely, as even low-dose statins provide cardiovascular benefit. 1, 4

Asian patients should start at rosuvastatin 5 mg daily due to higher systemic exposure. 3

Patients with severe renal impairment (not on dialysis) should start rosuvastatin at 5 mg daily and not exceed 10 mg daily. 3
