In an analysis of the Melagatran Thrombosis Prophylaxis in Orthopedic Surgery (METHRO) III study, we evaluated whether concomitant administration of aspirin (ASA) and non-steroidal anti-inflammatory drugs (NSAIDs) with the direct thrombin inhibitor melagatran/ximelagatran or the low-molecular-weight heparin enoxaparin increased bleeding in patients undergoing major joint surgery. Further objectives were to compare the influence of the timing of initial postoperative administration of melagatran/ximelagatran on bleeding in orthopedic patients receiving ASA/NSAIDs and in comparison with the preoperative administration of enoxaparin. ASA or NSAIDs in conjunction with melagatran/ximelagatran or enoxaparin did not increase bleeding. Bleeding rates were not significantly different, irrespective of the timing of the initial postoperative dose of melagatran/ximelagatran (4-8 vs. 4-12 h) when compared with preoperative (12 h) administration of enoxaparin. Transfusion rates were significantly lower with administration of melagatran/ximelagatran compared with enoxaparin.
