Lipitor is a brand-name drug that contains atorvastatin calcium, which is used to lower cholesterol levels in the blood. According to the first source [1], the patent for Lipitor expired in 2011, which means that other companies can now produce and sell generic versions of the drug. This can lead to cost savings for patients, as generic drugs are usually cheaper than their brand-name counterparts.

The second source [2] provides information on cost-saving options for Lipitor specifically. The manufacturer of Lipitor, Pfizer, offers a savings card for eligible patients that can help reduce the cost of the drug. The card can be used at most pharmacies and can save patients up to $75 on each prescription. Patients can also sign up for the Lipitor Choice Program, which offers a 90-day supply of the drug for a flat fee of $99.

In addition to these options, patients can also look into purchasing atorvastatin calcium, the generic version of Lipitor. According to the third source [3], generic drugs are usually much cheaper than brand-name drugs, and can be just as effective. Patients should talk to their doctor or pharmacist to determine if atorvastatin calcium is a suitable alternative to Lipitor.

In conclusion, there are several cost-saving options for Lipitor. Patients can look into purchasing the generic version of the drug, using a savings card or signing up for the Lipitor Choice Program offered by the manufacturer. Patients should also consult with their doctor or pharmacist to determine the best option for their individual needs.
