The combination of dipyridamole and coumarin anticoagulants does not alter the prothrombin time, but might cause an increased risk of serious bleeding when compared with anticoagulants alone. There is some evidence that the risk of bleeding may be lower, without a reduction in efficacy, if the INR is maintained within a lower range.
