in two hours, which can remove the use of “bridging”with a low-molecular-weight heparin or unfractionatedheparin. The half-life is 14 to 17 hours with several doses.Dabigatran undergoes conjugation with glucuronic acid; 80%of the drug is eliminated renally.The dose is 150 mg twice daily, decreased to 75 mg Decitabine twicedaily for patients with a creatinine clearanceof below30 mL/minute. It is not advisable for patients with a CrClof much less than 15 mL/minute or for hemodialysis patients becauseof a lack of adequate evidence supporting its use in this population.46Dabigatran does not inhibit or induce the CYP isoenzymes,and it isn't metabolized by CYP isoenzymes.47 Dabigatranshould be avoided with P-glycoprotein inducers.
Dose adjustments aren't essential for use withP-glycoprotein inhibitors such as amiodarone, clarithromycin, diltiazem, ketoconazole,quinidine, and verapamil.Dabigatran is regarded Decitabine a Pregnancy Class C medication;it's unknown no matter if it's excreted in breast milk.46 Based onits pharmacokinetic/pharmacodynamic profile and its quickonset of action, this agent would be an ideal alternative to warfarinto lessen the risk of stroke in patients with AF or atrialflutter.Data from a pilot trial—PETRO—suggested that dabigatran may be a suitable substitutefor warfarin to reduce the risk of thromboembolic events inthose with AF.48 According to these results, the Randomized Evaluationof Long-term Anticoagulation Therapytrialwas conducted. In this trial 18,113 subjects with AF at risk forthromboembolism were randomly assigned to receive warfarinor certainly one of two doses of dabigatran 110 or150 mg twice daily.
Of note, patients with a CrCl of much less Doxorubicin than30 mL/minute were excluded from the trial.The primary endpoint of this non-inferiority trialwas stroke or systemic embolism. Significant bleeding in this trialwas defined as a drop in hemoglobin of 2 g/L, transfusion of2 or much more units of blood, or symptomatic bleeding in a criticalarea or organ.Patients were evaluated for a median of two years. The primaryendpoint occurred in 182 patients receiving dabigatran110 mgand in 199of thosereceiving warfarin. The rate of AEs inthose receiving dabigatran 150 mg was 134.The risk of hemorrhagic stroke was substantially reducedwith dabigatran 110 mgand 150 mgwhen comparedwith warfarin. Significant bleeding was substantially reducedwith dabigatran 110 mg compared with warfarinbut not with 150 mg compared withwarfarin.
The PARP rate of GI bleeding, no matter if life-threatening or not,was higher in the 150-mg dabigatran group than in the warfaringroup.The rate of intracranial hemorrhage was substantially higherwith warfarin. AE rates were 0.74% per year with warfarin and0.3% per year with dabigatran 150 mg.39The 150-mg dose was connected with a reduce risk of strokeor systemic embolism than the 110-mg dose, but no statistical difference in majorbleeding was seen. Thedifference in the primary endpoint in between the doses wasdriven by a difference in the risk of stroke brought on by ischemicor unspecified causes. The rate of MI was significantlyincreased with both dabigatran 110 mg] and dabigatran 150 mgcompared with warfarin.
Unlike the riskof hepatotoxicity noted with ximelagatran, one more directthrombin inhibitor, dabigatran in this trial was not associatedwith hepatoxicity or elevated levels Doxorubicin in liver function tests. Dyspepsiawas the only other AE seen much more usually in patients receivingdabigatran.39Subsequently, the RE-LY investigators published reviseddata for the primary endpoint as well as the rate of MI that occurredduring the trial according to newly identified events. Incorporationof these results did not alter the primary efficacy or safetyresults. On the other hand, the difference in the rate of MI in the Decitabine comparisonof the 150-mg dose with placebo was no longer considerable.40The RE-LY findings suggested that dabigatran could possibly be analternative to warfarin for lowering the risk of stroke and systemicembolism in patients with AF and risk factors for stroke.
The 150-mg dose supplied far better stroke and systemic embolismprotection than Doxorubicin warfarin, but there was no difference in the riskof bleeding. The FDA did not approve the 110-mg dose that wasused in the RE-LY trial, in all probability because of the increasedrisk of ischemic strokes in this group. The 75-mg dose that theFDA did approve for patients with renal impairment has notbeen evaluated in clinical trials.Warfarin is readily available as a generic medication, but therapycomes with the added price of office visits and laboratory monitoring.Though patients receiving dabigatran do not requirespecific monitoring, the cost with the medication is significantly higherthan that of warfarin. Consequently, a cost-effectiveness analysisusing data primarily from RE-LY was conducted. The cost ofdabigatran employed in this analysiswas estimated according to pricingfrom the United kingdom. Total costsassociatedwith warfarin were $143,193 and $168,398 for dabigatran150 mg twice daily.The incremental cost-effectiveness ratio was $45,372 per quality-adjusted life yearwith dabigatran
