Pradaxa Thrombin Inhibitor

Pradaxa / The Maher Law Firm


One month after 50 cases of fatal bleeding incidents were reported, the U.S. Food and Drug Administration announced that it will conduct a complete safety review of the drug, Pradaxa (dabigatran). Pradaxa is an oral direct thrombin inhibitor that is used to prevent stroke in patients suffering from non valvular atrial fibrillation. The FDA’s safety review will allow the agency to better determine whether or not the reports of bleeding are occurring more commonly than would be expected.

The FDA granted limited approval of Pradaxa in October 2010, allowing the drug to be used in two doses, the 150mg bid and 75mg bid. This limitation was immediately questioned given the fact the 75mg dose had never actually been formally tested in clinical trials. In fact, an article published in the New England Journal of Medicine reported commentary from FDA researchers that specifically noted a “prevailing concern about the potential for excess bleeding.”

The drug’s maker, Boehringer Ingelheim, maintains that Pradaxa’s safety profile was in line with what had been seen in its clinical trials.
