Brand name : LIXIANA TABLETS 30 mg Active ingredient: Edoxaban tosilate hydrate Dosage form: slightly red tablet, φ: 8.6 mm, thickness: 3.8 mm Printings on wrapping: 甲苯磺酸依度沙班片 30mg DSC472 LIXIANA 30mg Effects of this medicine This medicine suppresses coagulation by inhibiting active blood coagulation factor X in the process of coagulation. After surgery, coagulation tends to occur because of hemostatic action, and with vascular injury and bedrest, blood is more likely to come coagulated. Especially, when blood clots (thrombi) are formulated on the leg and move through vessels to lung, they may become stuck in the lung vessels. The medicine suppresses thrombus formation. It is used for suppression of venous thrombosis in patients who underwent surgery for total knee replacement, total hip replacement or hip fracture.
