What is Lipitor?
Lipitor (atorvastatin) is a medication that is used to lower cholesterol and reduce the risk of heart attack, stroke, heart disease, and cardiovascular disease. Lipitor belongs to a large class of drugs known as statins, which prevent the liver from making low density lipoprotein (LDL cholesterol) by inhibiting an enzyme called HMG-CoA reductase.
Lipitor was created by Pfizer Inc. and approved by the U.S. Food and Drug Administration (FDA) in 1997. In just a few years, it quickly became the most-prescribed medication in the entire world and the most lucrative drug in history. Until the patent on Lipitor expired in November 2011, Pfizer raked in $11 billion in revenue on the drug every year.
What is the problem with Lipitor?
Many experts believe that Lipitor is over-prescribed to people who do not need it, which is concerning, because they may be at risk of severe side effects, including type-2 diabetes.
Although studies have found that Lipitor is effective for reducing mortality in patients with pre-existing cardiovascular disease and high cholesterol, it is not clear that people without pre-existing cardiovascular disease benefit from Lipitor. A growing number of Lipitor lawsuits allege that Pfizer aggressively marketed Lipitor without warning about the potential dangers.
Lipitor and Type-2 Diabetes
Studies of Lipitor and type-2 diabetes have found that it can elevate blood-sugar levels, which may cause new onset of type-2 diabetes. Unfortunately, people with type-2 diabetes suffer from chronic blood-sugar control problems. It can dramatically shorten a person’s lifespan and lead to fatal complications if it is not controlled.
Although the increased risk of diabetes from Lipitor appears to be small, it is dramatically higher for people with certain risk factors:
- Excess weight or obesity
- High blood sugar
- Insulin resistance
- High triglycerides (blood fat)
- High blood pressure
- Family history of type-2 diabetes
- Sedentary lifestyle
- Age (being over 45)
FDA Warnings for Lipitor and Diabetes
In response to years of research linking Lipitor and diabetes, the U.S. Food and Drug Administration (FDA) published this Drug Safety Communication in February 2012 to warn about the risk and update the label.
The warning for Lipitor was based on “reports of increased blood sugar and glycosylated hemoglobin (HbA1c) levels.” Diabetics who have high glycosylated hemoglobin have poorer control over blood-sugar levels. They also have a significantly higher risk of heart problems and kidney damage.
The FDA Safety Warning was also concerned about the following clinical studies:
- JUPITER Clinical Trial: Researchers found that Crestor, a statin that is very similar to Lipitor, was associated with a 27% increased reports of diabetes compared to patients taking a placebo.
- PROVE-IT TIMI 22 sub-study: Lipitor was specifically associated with increased blood-sugar levels.
Studies of Lipitor and Diabetes
Researcher have published numerous studies linking statins, Lipitor, and type-2 diabetes. Some of these studies include:
- The Lancet published a study in February 2010 that found a 9% increased risk of diabetes in patients taking statins, based on a meta-analysis of 13 clinical trials.
- The Journal of the American College of Cardiology published a study in March 2011 that linked higher doses of Lipitor to higher rates of diabetes.
- The Journal of the American Medical Association (JAMA) published a study in June 2011 that found a 12% increased risk of diabetes associated with statins. Researchers estimated there would be one extra case of diabetes for every 500 people who took a statin.
- The JAMA Internal Medicine published a study in January 2012 that found post-menopausal women who took a statin were 50% more likely to develop diabetes. Conclusions were based on more than 161,000 women between the ages of 50 and 79. Within nine years, 6.4% of women who did not take statins had diabetes, compared to 10% of the women who took statins.
