Rapid Summary

Overview

Highly potent, long-acting statin. The cornerstone of primary and secondary prevention of atherosclerotic cardiovascular disease.

Maximum Dose

Max 80 mg/day (Used for high-intensity secondary prevention post-MI/CVA).

Clinical Focus

Does not require evening dosing due to its long half-life. Monitor for muscle pain and dark urine.

Bottom Line

Atorvastatin is the most prescribed statin with the broadest evidence base for cardiovascular risk reduction, but myalgia is common and rhabdomyolysis, though rare, requires vigilance.

Formulation & Access

Brand Names

Lipitor, Lorstat

Oral Routes

Tablets (10 mg, 20 mg, 40 mg, 80 mg).

Prescribing & PBS

Unrestricted General Benefit (S4).

Indications & Use

Primary

PBSTGA

Hypercholesterolemia, high CV risk, post-MI, post-CVA.

Clinical Place

First-line lipid-lowering agent. Exhibits powerful pleiotropic anti-inflammatory effects that stabilize atherosclerotic plaques.

Class & Role

HMG-CoA Reductase Inhibitor — Highly potent, long-acting statin.

Route / Formulation

Tablets (10 mg, 20 mg, 40 mg, 80 mg). (Lipitor, Lorstat)

Usual Dose & Max

PO 10-20 mg OD. Max 80 mg/day (Used for high-intensity secondary prevention post-MI/CVA).

Key Indication Doses

Primary Prevention: PO 10-20 mg OD. Secondary Prevention (Post-MI/Stroke): PO 40-80 mg OD. High-intensity therapy is mandatory unless contraindicated. Elderly / Frail: Consider starting at 10-20 mg OD due to increased myopathy risk.

Best Uses

Atorvastatin is the most prescribed statin with the broadest evidence base for cardiovascular risk reduction, but myalgia is common and rhabdomyolysis, though rare, requires vigilance.

Avoid / Cautions

Active liver disease, unexplained persistent transaminitis. Pregnancy Category D (Cholesterol is essential for fetal development).

Key Risks

Musculoskeletal: Myalgia (muscle aches), myopathy. CRITICAL — Rhabdomyolysis (muscle breakdown releasing myoglobin, causing renal failure). Hepatic: Transaminitis (elevated ALT/AST). Metabolic: Mildly increases risk of new-onset Type 2 Diabetes.

Key Interactions

Metabolised exclusively by CYP3A4. Inhibitors (Clarithromycin, Grapefruit juice, Amiodarone, Diltiazem) massively increase Atorvastatin levels, precipitating rhabdomyolysis. Gemfibrozil (Fibrate) blocks statin uptake, drastically increasing blood levels. Avoid combo.

Monitoring

Baseline and routine Lipids (to assess efficacy) and LFTs. Check CK (Creatine Kinase) if muscle pain occurs. Ask about unexplained muscle pain, weakness, or brown/dark urine at every review.

Clinical Pearl

Unlike older statins (Simvastatin/Pravastatin) which have short half-lives and must be taken strictly at night when cholesterol synthesis peaks, Atorvastatin's long half-life allows it to be taken at any time of day.
