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 a number of doses.Dabigatran undergoes conjugation with glucuronic acid; 80%of the drug is eliminated renally.The dose is 150 mg twice every day, decreased to 75 mg Decitabine twicedaily for patients having a creatinine clearanceof below30 mL/minute. It isn't advised for patients having a CrClof 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 required for use withP-glycoprotein inhibitors including amiodarone, clarithromycin, diltiazem, ketoconazole,quinidine, and verapamil.Dabigatran is deemed Decitabine a Pregnancy Class C medication;it's unknown no matter whether 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 reduce the risk of stroke in patients with AF or atrialflutter.Data from a pilot trial—PETRO—suggested that dabigatran may well be a suitable substitutefor warfarin to reduce the risk of thromboembolic events inthose with AF.48 Based on 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 every day.
Of note, patients having a CrCl of less Doxorubicin than30 mL/minute were excluded from the trial.The principal endpoint of this non-inferiority trialwas stroke or systemic embolism. Main bleeding in this trialwas defined as a drop in hemoglobin of 2 g/L, transfusion of2 or far more units of blood, or symptomatic bleeding inside a criticalarea or organ.Individuals were evaluated to get 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. Main bleeding was substantially reducedwith dabigatran 110 mg compared with warfarinbut not with 150 mg compared withwarfarin.
The PARP rate of GI bleeding, no matter whether life-threatening or not,was higher within the 150-mg dabigatran group than within 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 associated having a reduce risk of strokeor systemic embolism than the 110-mg dose, but no statistical difference in majorbleeding was seen. Thedifference within the principal endpoint between the doses wasdriven by a difference within the risk of stroke caused by ischemicor unspecified causes. The rate of MI was significantlyincreased with both dabigatran 110 mg] and dabigatran 150 mgcompared with warfarin.
In contrast to the riskof hepatotoxicity noted with ximelagatran, another directthrombin inhibitor, dabigatran in this trial was not associatedwith hepatoxicity or elevated levels Doxorubicin in liver function tests. Dyspepsiawas the only other AE seen far more often in patients receivingdabigatran.39Subsequently, the RE-LY investigators published reviseddata for the principal endpoint along with the rate of MI that occurredduring the trial according to newly identified events. Incorporationof these results did not change the principal efficacy or safetyresults. On the other hand, the difference within the rate of MI within the Decitabine comparisonof the 150-mg dose with placebo was no longer significant.40The RE-LY findings suggested that dabigatran may be analternative to warfarin for reducing the risk of stroke and systemicembolism in patients with AF and risk aspects for stroke.
The 150-mg dose offered superior stroke and systemic embolismprotection than Doxorubicin warfarin, but there was no difference within the riskof bleeding. The FDA did not approve the 110-mg dose that wasused within the RE-LY trial, almost certainly 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 obtainable as a generic medication, but therapycomes using the added price of office visits and laboratory monitoring.Though patients receiving dabigatran do not requirespecific monitoring, the cost from the medication is significantly higherthan that of warfarin. Consequently, a cost-effectiveness analysisusing data mainly from RE-LY was conducted. The cost ofdabigatran utilized in this analysiswas estimated according to pricingfrom the United kingdom. Total costsassociatedwith warfarin were $143,193 and $168,398 for dabigatran150 mg twice every day.The incremental cost-effectiveness ratio was $45,372 per quality-adjusted life yearwith dabigatran
