The Food and Drug Administration has approved two applications for first generic versions of apixaban (Eliquis, Bristol-Myers Squibb/Pfizer) tablets to reduce the risk for stroke and systemic embolism in patients with nonvalvular atrial fibrillation.
The FDA gave the go-ahead to market generic versions of apixaban to Micro Labs Limited and Mylan Pharmaceuticals.
“Today’s approvals of the first generics of apixaban are an example of how the FDA’s generic drug program improves access to lower-cost, safe, and high-quality medicines,” Janet Woodcock, MD, director of the FDA’s Center for Drug Evaluation and Research, said in a statement today. “These approvals mark the first generic approvals of a direct oral anticoagulant.”
It is estimated that between 2.7 and 6.1 million people in the United States have atrial fibrillation. Many of these individuals use anticoagulants or anticlotting drugs to reduce that risk. Direct oral anticoagulants, however, do not require repeated blood testing.
Apixaban was approved by the FDA in December 2012 for the prevention of stroke and systemic embolism in patients with nonvalvular atrial fibrillation. Additional indications in the United States are to treat and prevent the recurrence of deep vein thrombosis (DVT) and pulmonary embolism (PE) and as DVT/PE prophylaxis in adults who have undergone hip or knee replacement surgery.
The FDA reminds providers that, as with brand name apixaban, generic versions must be dispensed with a medication guide that provides important instructions on the drug’s uses and risks. Healthcare professionals should counsel patients on signs and symptoms of possible bleeding.
As with other FDA-approved anticlotting drugs, bleeding, including life-threatening and fatal bleeding, is the most serious risk with apixaban.
Full prescribing information for the drug also warns about the increased risk for stroke in patients who discontinue use of the drug without taking some other form of anticoagulation. Epidural or spinal hematoma, which may cause long-term or permanent paralysis, may occur in patients treated with apixaban who are undergoing spinal epidural anesthesia or spinal puncture.
