Lipitor (atorvastatin) is a widely used statin drug that is prescribed to lower cholesterol levels and reduce the risk of heart attack and stroke. When compared to other statins, Lipitor has a higher cost, but it is also considered to be more potent.

According to the drug patent watch website [1], Lipitor is the brand name for atorvastatin, which was first approved by the FDA in 1996. The patent for Lipitor expired in 2011, and since then, several generic versions of atorvastatin have become available. The availability of generic atorvastatin has made it more affordable for patients who cannot afford the brand-name version.

GoodRx [2] provides a comparison chart for the intensity of different statins. The chart shows that atorvastatin (Lipitor) is considered a high-intensity statin, along with rosuvastatin (Crestor). High-intensity statins are more effective at lowering LDL cholesterol levels than moderate-intensity statins such as lovastatin (Mevacor) and simvastatin (Zocor).

Drugs.com [3] provides a comparison of atorvastatin (generic) and Lipitor (brand name). The comparison shows that the generic version of atorvastatin is significantly less expensive than Lipitor. The website also notes that the generic version of atorvastatin is just as effective as Lipitor in lowering cholesterol levels.

In conclusion, Lipitor (atorvastatin) is a high-intensity statin that is more expensive than other statins, but it is also considered to be more potent. The availability of generic atorvastatin has made it more affordable for patients who cannot afford the brand-name version. Patients should discuss with their healthcare providers to determine which statin is best for them based on their individual health needs and budget.
