Renal Dose
Renal impairment (nonvalvular AF)
CrCl 30-50 mL/min: 20 mg/day
CrCl 15-50 mL/min: 15 mg/day
ESRD on intermittent renal dialysis: 15 mg/day
Renal impairment (postoperative thromboprophylaxis)
CrCl >50 mL/min: Dose adjustment not necessary
CrCl 30-50 mL/min: Use with caution; dose adjustment not necessary
CrCl <30 mL/min: Avoid use
Contraindication
Patient w/ active pathologic bleeding, significant risk of major bleeding (e.g. recent GI ulcer, oesophageal varices, recent brain, spine, or ophth surgery, recent intracranial haemorrhage, malignant neoplasms, vascular aneurysm).
Mode of Action
Factor Xa inhibitor that inhibits platelet activation by selectively blocking the active site of factor Xa without requiring a cofactor (eg, antithrombin III) for activity.
Blood coagulation cascade is dependent on the activation of factor X to factor Xa via the intrinsic and extrinsic pathways plays a central role in the blood coagulation cascade.
Dose-dependent inhibition of factor Xa activity observed; antifactor Xa activity is also influenced by rivaroxaban; prolongs PT and aPTT and HepTest .
Precaution
Patient w/ hepatic disease associated w/ coagulopathy, severe HTN, prosthetic heart valve, vascular retinopathy, bronchiectasis. Anaesth w/ post-op indwelling epidural catheter. Hepatic and renal impairment. Pregnancy and lactation.
Lactation: Unknown whether distributed in human breast milk; not recommended; a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother
