Lipitor is a brand-name drug that contains atorvastatin, which is used to lower cholesterol levels and reduce the risk of heart attack and stroke. According to the sources provided, Lipitor is covered by Medicare, but the coverage may vary depending on the specific plan.

The first source, Drug Patent Watch [1], provides information about the patent status of Lipitor. The patent for Lipitor expired in 2011, which means that generic versions of atorvastatin are available. However, the availability of generic versions does not affect the coverage of Lipitor by Medicare.

The second source, Medicare.org [2], confirms that Lipitor is covered by Medicare Part D, which is the prescription drug coverage plan. However, the coverage may vary depending on the specific plan and the pharmacy that the patient uses. Medicare Part D plans have a formulary, which is a list of covered drugs. Lipitor may be included in the formulary, but the patient may need to pay a copayment or coinsurance.

The third source, GoodRx [3], provides information about the cost of atorvastatin with Medicare coverage. The cost may vary depending on the specific plan and the pharmacy that the patient uses. GoodRx also provides a list of pharmacies that offer atorvastatin at a discounted price for Medicare patients.

In conclusion, Lipitor is covered by Medicare, but the coverage may vary depending on the specific plan and the pharmacy that the patient uses. Patients should check their plan's formulary and contact their pharmacy to confirm the cost of Lipitor with their Medicare coverage.
