Prevention of recurrent DVT &/or PE & related death.
Dosage/Direction for Use
Adult & elderly Prevention of VTE in patient who have undergone major orthopaedic surgery 220 mg once daily taken as 2 cap of 110 mg. Prevention of stroke, systemic embolism & reduction of vascular mortality in patient w/ atrial fibrillation 300 mg taken as 150 mg bid. Therapy should be continued life-long. Treatment of acute DVT &/or PE & prevention of related death 300 mg taken as 150 mg bid following treatment w/ a parenteral anticoagulant for at least 5 days.

Adult Prevention of VTE following knee or hip replacement surgery Initially 110 mg w/in 1-4 hr of completed surgery & continuing w/ 2 cap of 110 mg once daily thereafter for a total of 10 days (following knee replacement surgery) or 28-35 days (following hip replacement surgery). Delay initiation of treatment for both surgeries if haemostasis is not secured. Initiate 2 cap of 110 mg once daily if the treatment is not started on the day of surgery. Elderly ≥80 yr Prevention of stroke, systemic embolism & reduction of vascular mortality in patient w/ atrial fibrillation 220 mg taken as 110 mg bid. Moderate renal impairment (CrCl 30-50 mL/min) or concomitant use w/ strong P-gp inhibitors (eg, amiodarone, quinidine or verapamil) Prevention of VTE in patient who have undergone major orthopaedic surgery 150 mg once daily as 2 cap of 75 mg. Prevention of VTE events following knee or hip replacement surgery Initially 75 mg w/in 1-4 hr of completed surgery & continuing w/ 2 cap of 75 mg once daily thereafter for a total of 10 days (following knee replacement surgery) or 28-35 days (following hip replacement surgery). Delay initiation of treatment for both surgeries if haemostasis is not secured. Initiate 2 cap of 75 mg once daily if the treatment is not started on the day of surgery. Patient at risk of bleeding (eg, ≥75 yr, moderate renal impairment, concomitant use w/ strong P-gp inhibitors) 220 mg taken as 110 mg bid. Catheter ablation for atrial fibrillation 150 mg bid.

Discontinue use at least 12 hr for acute surgery or at least 24 hr prior to invasive or surgical procedures or 2-4 days in major surgery where complete hemostasis may be required. Increased risk of spinal or epidural hematoma in case of traumatic or repeated puncture & by prolonged use of epidural catheters; an interval of at least 1 hr after removal of catheter should elapse before the administration of the 1st dose.
