March of 2012 saw the first lawsuits filed against Boehringer Ingelheim, the manufacturer of Pradaxa. This drug was the first of its type to be marketed in over half a century, and Boehringer had high hopes that Pradaxa would knock its only competitor, Warfarin, out of the running in short order. Pradaxa works differently from Warfarin; while both drugs are used to prevent stroke in patients with atrial fibrillation, Warfarin works by inhibiting the production of Vitamin K, a clotting agent in the body. Should there be excessive bleeding in a patient who has taken Warfarin, doses of Vitamin K can be administered to slow the bleeding. Pradaxa, on the other hand, works by inhibiting thrombin, an enzyme in the blood which also controls blood clotting. At this time there is no known antidote to Pradaxa in the event it leads to excessive or uncontrollable bleeding.
What is Atrial Fibrillation?
Atrial fibrillation affects more than two million Americans and is characterized by rapid, uncoordinated contractions in the upper chambers of the heart. Patients with atrial fibrillation are at a much higher risk of developing blood clots, and since the 1950’s doctors have been using Warfarin—which is also known as Coumadin—to help lessen the likelihood of stroke. The FDA approved Pradaxa for use in patients with atrial fibrillation in October of 2010, yet less than a year later reports were coming in regarding serious side effects and even death among Pradaxa users. In December of 2011, in the face of hundreds of adverse reports, the FDA issued a safety warning to patients and physicians, stating they would taking a hard look at the prior Pradaxa studies.
