Atorvastatin (Atorva) Tablet Indications
Atorvastatin is FDA-approved for cardiovascular risk reduction in patients with or without established coronary disease, and as lipid-lowering therapy for primary hyperlipidemia, familial hypercholesterolemia, dysbetalipoproteinemia, and hypertriglyceridemia. 1
FDA-Approved Cardiovascular Risk Reduction Indications
Atorvastatin reduces cardiovascular events in the following populations 1:
Primary prevention in patients without clinically evident CHD: Reduces risk of myocardial infarction, stroke, revascularization procedures, and angina in adults with multiple CHD risk factors 1
Primary prevention in type 2 diabetes: Reduces MI and stroke in adults with type 2 diabetes and multiple CHD risk factors but without clinically evident CHD 1
Secondary prevention in established CHD: Reduces non-fatal MI, fatal and non-fatal stroke, revascularization procedures, hospitalization for congestive heart failure, and angina in adults with clinically evident CHD 1
FDA-Approved Lipid-Lowering Indications
Atorvastatin is indicated as adjunct to diet for 1:
Primary hyperlipidemia: To reduce LDL-C in adults 1
Heterozygous familial hypercholesterolemia (HeFH): In adults and pediatric patients aged 10 years and older 1
Homozygous familial hypercholesterolemia (HoFH): As adjunct to other LDL-C-lowering therapies, or alone if such treatments are unavailable, in adults and pediatric patients aged 10 years and older 1
Primary dysbetalipoproteinemia: In adults 1
Hypertriglyceridemia: In adults 1
Guideline-Recommended Indications for Specific Populations
Secondary Prevention After Ischemic Stroke/TIA
Atorvastatin 80 mg daily is specifically indicated for stroke prevention in patients with recent ischemic stroke or TIA without known coronary disease and LDL-C >100 mg/dL. 2 This high-intensity regimen reduces stroke recurrence risk 2 and is recommended across all resource settings globally 2
For patients with ischemic stroke/TIA and atherosclerotic disease (intracranial, carotid, aortic, or coronary), atorvastatin combined with ezetimibe if needed should target LDL-C <70 mg/dL to reduce major cardiovascular events 2
Atherosclerotic Cardiovascular Disease (ASCVD)
In patients with clinical ASCVD, atorvastatin 80 mg daily is first-line therapy to achieve LDL-C reduction ≥50% and target LDL-C <70 mg/dL. 3, 4 High-intensity atorvastatin (40-80 mg) reduces ASCVD events by 37% compared to moderate-intensity therapy 4
If LDL-C remains >70 mg/dL on maximally tolerated atorvastatin, add ezetimibe 10 mg daily for an additional 15-25% LDL-C reduction 2, 5
Diabetes Mellitus
For diabetic patients aged 40-75 years without ASCVD, atorvastatin 10-20 mg daily (moderate-intensity) is indicated for primary prevention. 4 In the CARDS trial, atorvastatin 10 mg reduced major cardiovascular events by 37% in diabetic patients 4
For diabetic patients with established ASCVD, treat as secondary prevention with atorvastatin 80 mg targeting LDL-C <70 mg/dL 5
Chronic Kidney Disease
Atorvastatin 20 mg is recommended for both primary and secondary prevention in patients with CKD (excluding hemodialysis) 4
Dosing by Indication
The FDA-approved dosage range is 10-80 mg once daily, taken at any time with or without food 1:
- Secondary prevention/high-risk ASCVD: Start atorvastatin 40-80 mg daily 4, 1
- Primary prevention/moderate risk: Start atorvastatin 10-20 mg daily 4, 1
- Patients requiring >45% LDL-C reduction: Start atorvastatin 40 mg daily 1
- Pediatric HeFH (age ≥10 years): Start 10 mg daily, range 10-20 mg daily 1
- Pediatric HoFH (age ≥10 years): Start 10-20 mg daily, range 10-80 mg daily 1
Important Dosing Restrictions
Do not exceed atorvastatin 20 mg daily when co-administered with saquinavir plus ritonavir, darunavir plus ritonavir, fosamprenavir, fosamprenavir plus ritonavir, elbasvir plus grazoprevir, letermovir, clarithromycin, or itraconazole. 1
Do not exceed atorvastatin 40 mg daily with nelfinavir 1
Common Pitfall to Avoid
Do not use atorvastatin 10 mg for secondary prevention in patients <75 years who can tolerate higher doses—this represents significant undertreatment. 4 Patients with established ASCVD require high-intensity therapy (atorvastatin 40-80 mg) unless contraindicated or not tolerated 2, 4
