Pfizer's Lipitor (atorvastatin) is a record-breaking drug, a prescription with the highest peak sales of any drug on the market. Statin drugs like this one, along with other brand equivalents and generics, are a medical doctor's go-to "solution" for managing patient's cholesterol levels. These drugs are formulated to alter liver function, reducing the efficiency of a specific liver enzyme that produces cholesterol. Under the spell of statins, liver cells are then more capable of capturing low-density lipoprotein cholesterol from the blood of patients, potentially reducing risk of heart attack and stroke. Statin drugs are often prescribed after one has suffered a major vascular event to prevent future incidents. However, suppressing the natural function of enzymes in the liver may very well invite new problems in the human body.
