One important caveat is that there must be dabigatran in the bloodstream for idarucizumab to have any effect. Once the dabigatran is cleared by the kidney, idarucizumab will have nothing to bind to and will have no effect. It is recommended to give it if the last dose of dabigatran was in the last hours.
There may be some benefit of longer time frames in patients with renal failure, who will have a slower clearance rate of the dabigatran. Finally, since it is a monoclonal antibody, it is highly specific for dabigatran. It will not reverse the anticoagulant effects of coumadin, plavix, or other NOACs such as rivaroxaban.
The data on idarucizumab in patients who are actually bleeding or being operated on looks favorable as well. The Reversal Effects of Idarucizumab on Active Dabigatran RE-VERSE AD trial, a large international prospective cohort study of patients on dabigatran who receive idarucizumab either for serious bleeding or prior to an urgent surgical procedure, is still ongoing. These data mirror the safety and efficacy data on idarucizumab from earlier human and animal studies.
The FDA-approved dose for idarucizumab is 5 mg, which is administered as two separate 2. The second dose should be administered within 15 minutes of the first infusion. There is no dosing change needed for renal or hepatic impairment.
There are case reports of serious complications in patients receiving idarucizumab, including acute ischemic stroke, cardiac arrest, NSTEMI, DVT, and PE, but the incidence is thought to be extremely low. Your risk of developing a spinal or epidural blood clot is higher if:. If you take PRADAXA and receive spinal anesthesia or have a spinal puncture, your healthcare provider should watch you closely for symptoms of spinal or epidural blood clots.

The amount of sorbitol contained in each dose of idarucizumab is very high and the summary of product characteristics includes a warning about use in people with hereditary fructose intolerance. In certain clinical situations, administration of a second 5 g dose of idarucizumab may be considered.
People treated with idarucizumab may still need other supportive measures; these should be considered as medically appropriate. Anticoagulant therapy is used for preventing and treating thromboembolism across various clinical indications. Licensed oral anticoagulants that are used in the UK include warfarin, and the NOACs apixaban, dabigatran etexilate, edoxaban and rivaroxaban.
The most common adverse effect of anticoagulants is bleeding, ranging from mild events to serious and fatal haemorrhage. Until recently, there were no specific antidotes for NOACs, unlike warfarin. Idarucizumab is the first agent to be licensed to reverse the anticoagulant effect of a NOAC, and it is specific for dabigatran etexilate. This evidence summary looks at the evidence for the efficacy and safety of idarucizumab for reversing the anticoagulant effect of dabigatran etexilate.
Full text of introduction and current guidance. Idarucizumab Praxbind , Boehringer Ingelheim Limited is a humanised monoclonal antibody fragment Fab with a very high affinity to dabigatran. It potently and specifically binds to dabigatran and its metabolites, thereby preventing dabigatran from exerting its anticoagulant effect. Its action is specific to dabigatran etexilate and so it will not reverse the action of other anticoagulants idarucizumab summary of product characteristics.
