Apixaban acts by inhibiting coagulation, and thus prevents development of blood clots. As a result of FXa inhibition, apixaban prolongs clotting tests such as prothrombin time (PT), INR, and activated partial thromboplastin time (aPTT). Changes observed in these clotting tests at the expected therapeutic dose, however, are small, subject to a high degree of variability, and not useful in monitoring the anticoagulation effect of apixaban.

Apixaban is a substrate of both CYP3A4 and P-gp. Inhibitors of CYP3A4 and P-gp increase exposure to Apixaban and increase the risk of bleeding. Inducers of CYP3A4 and P-gp decrease exposure to Apixaban and increase the risk of stroke.

Apixaban can cause a skin rash or severe allergic reaction.

Pregnancy: There are no adequate and well-controlled studies of Apixaban in pregnant women. Treatment is likely to increase the risk of hemorrhage during pregnancy and delivery. Apixaban should be used during pregnancy only if the potential benefit outweighs the potential risk to the mother and fetus.

Labor and Delivery: Safety and effectiveness of Apixaban during labor and delivery have not been studied in clinical trials. Consider the risks of bleeding and of stroke in using Apixaban in this condition.

Nursing Mothers: It is unknown whether Apixaban or its metabolites are excreted in human milk. Women should be instructed either to discontinue breastfeeding or to discontinue Apixaban therapy, taking into account the importance of the drug to the mother.

Increased Risk of Stroke with Discontinuation of Apixaban Discontinuing Apixaban in the absence of adequate alternative anticoagulation increases the risk of thrombotic events. An increased rate of stroke was observed during the transition from Apixaban to warfarin in clinical trials in patients with nonvalvular atrial fibrillation. If Apixaban must be discontinued for a reason other than pathological bleeding, consider coverage with another anticoagulant.

Hepatic Impairment: No dose adjustment is required in patients with mild hepatic impairment. Because patients with moderate hepatic impairment may have intrinsic coagulation abnormalities and there is limited clinical experience with Apixaban in these patients, dosing recommendations cannot be provided Apixaban is not recommended in patients with severe hepatic impairment

Renal Impairment: The dosing adjustment for moderate renal impairment is described above. No data inform use in patients with creatinine clearance <15 ml/min or on dialysis.

Pediatric Use: Safety and effectiveness in pediatric patients have not been established.

Geriatric Use: Of the total subjects in clinical studies of Apixaban, >69% were 65 and older, and >31% were 75 and older. The effects of Apixaban on the risk of stroke and major bleeding compared to warfarin were maintained in geriatric subjects.

Anti-coagulants, Anti-platelet drugs, Fibrinolytics (Thrombolytics), Oral Anti-coagulants

There is no antidote to Apixaban. Overdose of Apixaban increases the risk of bleeding. Activated charcoal may be useful in the management of Apixaban overdose.

Keep in a dry place and store below 30°C. Protect from light and keep out of the reach of children.
