Lipitor is a brand-name drug that contains atorvastatin, which is used to lower cholesterol levels in the body. The drug is manufactured by Pfizer and has been available in the market since 1996. However, the patent for Lipitor expired in 2011, which means that other companies can now produce and sell generic versions of the drug [1].

Generic versions of Lipitor are available in various pharmacies and drugstores, and they are usually cheaper than the brand-name drug. The generic versions of Lipitor are also available online through various websites that sell prescription drugs. However, it is important to note that buying drugs online can be risky, and it is important to ensure that the website is reputable and that the drugs are safe and effective [2].

According to Everyday Health [3], some of the generic versions of Lipitor that are available in the market include Atorvastatin Calcium, Atorvastatin Calcium Tablets, and Atorvastatin Calcium Oral. These drugs are available in various strengths, and the dosage and frequency of use should be determined by a healthcare provider.

In conclusion, generic versions of Lipitor are available in various pharmacies and drugstores, as well as online through reputable websites. However, it is important to consult with a healthcare provider before using any medication and to ensure that the drugs are safe and effective.
