Dabigatran Etexilate Mesylate
Indications
Reduction of Risk of Stroke and Systemic Embolism in Non-valvular Atrial Fibrillation: Dabigatran Etexilate Mesylate is indicated to reduce the risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation. Treatment of Deep Venous Thrombosis and Pulmonary Embolism: Dabigatran Etexilate Mesylate is indicated for the treatment of deep venous thrombosis and pulmonary embolism in patients who have been treated with a parenteral anticoagulant for 5-10 days. Reduction in the Risk of Recurrence of Deep Venous Thrombosis and Pulmonary Embolism: Dabigatran Etexilate Mesylate is indicated to reduce the risk of recurrence of deep venous thrombosis and pulmonary embolism in patients who have been previously treated. Prophylaxis of Deep Vein Thrombosis and Pulmonary Embolism Following Hip Replacement Surgery: Dabigatran Etexilate Mesylate is indicated for the prophylaxis of deep vein thrombosis and pulmonary embolism, in patients who have undergone hip replacement surgery.
Pharmacology
Dabigatran and its acyl glucuronides are competitive, direct thrombin inhibitors. Because thrombin (serine protease) enables the conversion of fibrinogen into fibrin during the coagulation cascade, its inhibition prevents the development of a thrombus. Both free and clot-bound thrombin, and thrombin-induced platelet aggregation are inhibited by the active moieties. At recommended therapeutic doses, dabigatran etexilate prolongs the coagulation markers such as aPTT, ECT, and TT. INR is relatively insensitive to the exposure to dabigatran and cannot be interpreted the same way as used for warfarin monitoring. The aPTT test provides an approximation of Dabigatran Etexilate�s anticoagulant effect. The average time course for effects on aPTT, following approved dosing regimens in patients with various degrees of renal impairment is shown in Figure 2. The curves represent mean levels without confidence intervals; variations should be expected when measuring aPTT. While advice cannot be provided on the level of recovery of aPTT needed in any particular clinical setting, the curves can be used to estimate the time to get to a particular level of recovery, even when the time since the last dose of Dabigatran Etexilate is not precisely known. In the RE-LY trial, the median (10 th to 90 th percentile) trough aPTT in patients receiving the 150 mg dose was 52 (40 to 76) seconds.
Dosage Administration
Reduction in Risk of Stroke and Systemic Embolism in Non-valvular AF- CrCl >30 mL/min: 150 mg twice daily CrCl 15 to 30 mL/min: 75 mg twice daily CrCl <15 mL/min or on dialysis: Dosing recommendations cannot be provided CrCl 30 to 50 mL/min with concomitant use of P-gp inhibitors: Reduce dose to 75 mg twice daily if given with P-gp inhibitors dronedarone or systemic ketoconazole. CrCl <30 mL/min with concomitant use of P-gp inhibitors: Avoid co-administration Treatment of DVT and PE, Reduction in the Risk of Recurrence of DVT and PE- CrCl >30 mL/min: 150 mg twice daily CrCl ?30 mL/min or on dialysis: Dosing recommendations cannot be provided CrCl <50 mL/min with concomitant use of P-gp inhibitors: Avoid co-administration Prophylaxis of DVT and PE Following Hip Replacement Surgery- CrCl >30 mL/min: 110 mg for first day, then 220 mg once daily CrCl ?30 mL/min or on dialysis: Dosing recommendations cannot be provided CrCl <50 mL/min with concomitant use of P-gp inhibitors: Avoid co-administration. Reduction of Risk of Stroke and Systemic Embolism in Non-valvular Atrial Fibrillation: For patients with creatinine clearance (CrCl) >30 mL/min, the recommended dose of Dabigatran Etexilate is 150 mg taken orally, twice daily. For patients with severe renal impairment (CrCl 15-30 mL/min), the recommended dose of Dabigatran Etexilate is 75 mg twice daily. Dosing recommendations for patients with a CrCl <15 mL/min or on dialysis cannot be provided. Treatment of Deep Venous Thrombosis and Pulmonary Embolism: For patients with CrCl >30 mL/min, the recommended dose of Dabigatran Etexilate is 150 mg taken orally, twice daily, after 5-10 days of parenteral anticoagulation. Dosing recommendations for patients with a CrCl ?30 mL/min or on dialysis cannot be provided. Reduction in the Risk of Recurrence of Deep Venous Thrombosis and Pulmonary Embolism: For patients with CrCl >30 mL/min, the recommended dose of Dabigatran Etexilate is 150 mg taken orally, twice daily after previous treatment. Dosing recommendations for patients with a CrCl ?30 mL/min or on dialysis cannot be provided. Prophylaxis of Deep Vein Thrombosis and Pulmonary Embolism Following Hip Replacement Surgery: For patients with CrCl >30 mL/min, the recommended dose of Dabigatran Etexilate is 110 mg taken orally 1-4 hours after surgery and after hemostasis has been achieved, then 220 mg taken once daily for 28-35 days. If Dabigatran Etexilate is not started on the day of surgery, after hemostasis has been achieved initiate treatment with 220 mg once daily. Dosing recommendations for patients with a CrCl ?30 mL/min or on dialysis cannot be provided
Contraindications
Dabigatran Etexilate is contraindicated in patients with: Active pathological bleeding. History of a serious hypersensitivity reaction to Dabigatran Etexilate (e.g., anaphylactic reaction or anaphylactic shock). Mechanical prosthetic heart valve.
Side Effects
The following clinically significant adverse reactions are described elsewhere in the labeling: Increased Risk of Thrombotic Events after Premature Discontinuation Risk of Bleeding Spinal/Epidural Anesthesia or Puncture Thromboembolic and Bleeding Events in Patients with Prosthetic Heart Valves Increased Risk of Thrombosis in Patients with Triple-Positive Antiphospholipid Syndrome
Pregnancy And Lactation
Pregnancy: The limited available data on Dabigatran Etexilate use in pregnant women are insufficient to determine drug-associated risks for adverse developmental outcomes. There are risks to the mother associated with untreated venous thromboembolism in pregnancy and a risk of hemorrhage in the mother and fetus associated with the use of anticoagulant Lactation: There are no data on the presence of dabigatran in human milk, the effects on the breastfed child, or on milk production. Dabigatran and/or its metabolites were present in rat milk. Breastfeeding is not recommended during treatment with Dabigatran Etexilate.
Therapeutic
Pediatric Use: The safety and effectiveness of Dabigatran Etexilate in pediatric patients have not been established. Geriatric Use: Of the total number of patients in the RE-LY study, 82% were 65 and over, while 40% were 75 and over. The risk of stroke and bleeding increases with age, but the risk-benefit profile is favorable in all age groups.
Storage Conditions
Accidental overdose may lead to hemorrhagic complications. In the event of hemorrhagic complications, initiate appropriate clinical support, discontinue treatment with Dabigatran Etexilate, and investigate the source of bleeding. A specific reversal agent (idarucizumab) is available. Dabigatran is primarily eliminated by the kidneys with a low plasma protein binding of approximately 35%. Hemodialysis can remove dabigatran; however, data supporting this approach are limited. Using a high-flux dialyzer, blood flow rate of 200 mL/min, and dialysate flow rate of 700 mL/min, approximately 49% of total dabigatran can be cleared from plasma over 4 hours. At the same dialysate flow rate, approximately 57% can be cleared using a dialyzer blood flow rate of 300 mL/min, with no appreciable increase in clearance observed at higher blood flow rates. Upon cessation of hemodialysis, a redistribution effect of approximately 7% to 15% is seen. The effect of dialysis on dabigatran�s plasma concentration would be expected to vary based on patient specific characteristics. Measurement of aPTT or ECT may help guide therapy
