How do Lipitor and Crestor stack up for lowering cholesterol?
Lipitor (atorvastatin) and Crestor (rosuvastatin) are both statins that reduce LDL cholesterol and cut cardiovascular risk. Crestor typically lowers LDL more potently at equivalent doses—for instance, 10 mg Crestor drops LDL by about 50%, while 20 mg Lipitor achieves around 45%.[1] Large trials like JUPITER (for Crestor) and TNT (for Lipitor) show both reduce heart attacks and strokes similarly when LDL targets are met, but Crestor reaches those targets with lower doses.[2][3]
What do head-to-head studies say?
Direct comparisons, like the 2002 PULSAR trial, found 10 mg Crestor reduced LDL by 51.5% versus 40.6% for 20 mg Lipitor, with similar HDL boosts and side effect rates.[4] A 2005 meta-analysis of 167 trials ranked Crestor as the most effective for LDL reduction, followed closely by Lipitor.[5] Effectiveness depends on dose: high-dose Lipitor (80 mg) matches Crestor 40 mg in LDL drop (55-60%), but Crestor starts stronger at low doses.
Why might Crestor edge out Lipitor for some patients?
Crestor has higher potency due to its structure, allowing better liver uptake and longer half-life (19 hours vs. Lipitor's 14 hours).[6] It's preferred for high-risk patients needing aggressive LDL cuts (<70 mg/dL), like those with diabetes or prior heart events. Lipitor, however, has more outcome data from the 2005 PROVE-IT trial, proving 80 mg superiority over moderate statins for post-heart attack patients.[7]
Do they differ in heart protection beyond LDL?
Both slash major vascular events by 20-25% per 39 mg/dL LDL drop, per a 2010 Lancet analysis of 170,000 patients.[8] No clear winner—Lipitor's ASCOT trial showed benefits in hypertensives, while Crestor's HOPE-3 did so in primary prevention.[9][10] Real-world use favors Lipitor for its generic availability since 2011, making it cheaper.
What about side effects and who tolerates which better?
Muscle pain (myalgia) hits 5-10% on either, but Crestor may cause more at high doses due to potency; Lipitor links to slight diabetes risk increase (0.5-1% over placebo).[11] Liver enzyme rises are rare (<2%) for both. Patient reports on forums like Drugs.com rate Crestor slightly higher (5.9/10 vs. Lipitor's 5.3/10), citing fewer aches.[12]
Cost and availability differences
Lipitor generics cost $0.10-$0.50 per 20 mg pill; Crestor generics (since 2016) run $0.20-$1.00 for 10 mg. No active patents block either.[13] Doctors often start with generic atorvastatin for cost, switching to rosuvastatin if LDL goals aren't met.
