"Lipitor, Best-selling Drug Ever, Goes Off Patent"

     "Lipitor, Best-selling Drug Ever, Goes Off Patent", is an article in the LA Times, written by Shari Roan on November 30,2011. Lipitor is the top-selling drug that reduces LDL cholesterol "will cease being Pfizer's cash cow." The big drug will still be available, but there will be a less-expensive version called Atorvastin. Lipitor has mad more that a  hundred billion dollars, since it has been approved in 1997. Some of the patients fear that Atorvastin will not be as affective. But in 2010, there was a study conducted by Clinical Therapeutics. Patient received Lipitor in an eight-week study and had a 48 percent reduction of LDL and the patients that took the Atorvastin had a 44 percent reduction of LDL. Lipitor costs one-hundred sixty dollars each month, and and Atorvastin costs ten dollars per month.
       I think this topic is very important, because patients are paying so much for this pill, when there is another pill, which can have the same affect for a less price. Today, many people are not doing financially well. If they have this cholesterol problem, and could not afford to buy this expensive medication, now there is a solution.
