The wholesale price of Lipitor in the USA is not explicitly mentioned in the provided sources. However, we can gather some insights about drug pricing in general and Lipitor's patent expiration date, which could affect its price.
According to the article from US Pharmacist , the price of a drug is determined by various factors such as research and development costs, manufacturing expenses, marketing expenses, and the competition in the market. The article also mentions that the prices of drugs are typically higher in the USA than in other countries due to the lack of price regulation by the government.
Furthermore, the patent for Lipitor expired in 2011 , which allowed for the production of generic versions of the drug. Generic drugs are usually cheaper than brand-name drugs, and this increased competition could have led to a decrease in the wholesale price of Lipitor.
However, the report from the Public Interest Research Group  suggests that the prices of generic drugs are not necessarily lower than brand-name drugs. The report states that the prices of generic drugs have been increasing in recent years, and some generic drugs have even become more expensive than their brand-name counterparts.
In conclusion, while the exact wholesale price of Lipitor is not provided in the sources, we can assume that its price may have been affected by the expiration of its patent and the competition from generic versions. However, the pricing of drugs is a complex issue that is influenced by many factors, and the prices of generic drugs are not always lower than brand-name drugs.
