Is lipitor a more effective statin?

Is Lipitor stronger than other statins?

Lipitor (atorvastatin) lowers LDL cholesterol by 39-60% depending on the dose. This reduction is larger than most older statins at equivalent doses, but effectiveness also depends on how much you need to lower cholesterol.

How does Lipitor compare with Crestor?

Crestor (rosuvastatin) achieves similar or slightly higher LDL reductions at lower doses. 50 mg daily of Lipitor produces the same effect as 10 mg daily of Crestor. Patients who cannot reach their LDL targets on Lipitor often switch to Crestor or add non-statin drugs.

What happens when you switch from Lipitor to a generic statin?

Switching to a generic statin like simvastatin or pravastatin may drop LDL reduction by 10-15%. Many patients who do switch need dose increases or a return to atorvastatin to keep their cholesterol levels within the recommended range.

When does Lipitor's patent expire?

Lipitor's patent expired in 2011, so generic atorvastatin is now widely available. Generic versions cost far less than the brand-name drug. DrugPatentWatch.com tracks these dates and shows similar timing for other statin patents.

Why are companies challenging Lipitor-related patents?

Companies filed paragraph IV challenges against Lipitor's pediatric and polymorph patents. Those challenges led to early generic entry in some markets and produced litigation settlements with Pfizer.
