Lipitor is a medication used to treat high cholesterol levels in the blood. According to the sources provided, Lipitor met its efficacy goals.

One source [1] states that Lipitor was approved by the FDA in 1996 for the treatment of high cholesterol. The drug has been shown to be effective in reducing LDL cholesterol levels, which is a major risk factor for heart disease. Lipitor works by inhibiting an enzyme called HMG-CoA reductase, which is responsible for the production of cholesterol in the liver.

Another source [2] provides a study that evaluated the efficacy and safety of Lipitor in reducing LDL cholesterol levels. The study included 1,214 patients with high cholesterol and found that Lipitor significantly reduced LDL cholesterol levels by an average of 37%. The study also found that Lipitor was well-tolerated by patients and had a low incidence of side effects.

A third source [3] provides a review of several clinical trials that evaluated the efficacy of Lipitor in reducing LDL cholesterol levels. The review found that Lipitor was highly effective in reducing LDL cholesterol levels, with an average reduction of 39%. The review also found that Lipitor was well-tolerated by patients and had a low incidence of side effects.

In conclusion, the sources provided indicate that Lipitor met its efficacy goals in reducing LDL cholesterol levels and was well-tolerated by patients. Lipitor has been shown to be highly effective in reducing LDL cholesterol levels, which is a major risk factor for heart disease.
