According to the sources provided, the cost of online Lipitor generics varies depending on the manufacturer and the country. Lipitor is a brand name for atorvastatin, a medication used to lower cholesterol levels in the blood. The drug's patent expired in 2011, and since then, several companies have started producing generic versions of the drug.

DrugPatentWatch [1] lists several manufacturers of generic atorvastatin, including Teva, Mylan, and Watson. The website also provides information on the expiration dates of the drug's patents in different countries. This information can be used to determine when generic versions of the drug will become available in a particular market.

Gabionline [2] reports that the introduction of generic atorvastatin has led to a significant decrease in the price of the drug. The article cites a study that found that the price of atorvastatin decreased by an average of 85% after the introduction of generic versions. However, the price of the drug varies widely depending on the country. For example, the article notes that the price of atorvastatin in the United States is much higher than in other countries.

Another article from Gabionline [3] reports that Pfizer, the company that originally developed Lipitor, has been fighting to maintain its market share in the face of competition from generic manufacturers. The article notes that Pfizer has been offering discounts and rebates to customers to encourage them to continue using Lipitor rather than switching to a generic version of the drug.

In conclusion, the cost of online Lipitor generics varies depending on the manufacturer and the country. The introduction of generic atorvastatin has led to a significant decrease in the price of the drug, but the price still varies widely depending on the market. Pfizer has been fighting to maintain its market share in the face of competition from generic manufacturers by offering discounts and rebates to customers.
