uires no coagulation monitoringand can be offered when daily. It prolongs the Cell Signaling inhibitor activated partialthromboplastin time, but its effect is just not dose-linear andit is just not suitable for a precise quantification with the anticoagulanteffect. At least 80% of dabigatran is excreted unchangedvia the kidneys; consequently, the drug is contraindicatedin individuals with severe renal failure, with a creatinineclearance much less than 30 mL/min. Dabigatran etexilatehas been already licensed in the European Union andin Canada for the prevention of VTE in individuals undergoinghip- and knee-replacement surgery, with a recommendeddose of 220 mg when daily for all individuals but those withmoderate renal insufficiencyand the elderly, forwhom the recommended dose is 150 mg when daily.A dose reduction is also recommended for individuals on amiodaronetreatment.
Dabigatran etexilate is at present undergoing a large phaseIII plan for the evaluation of its efficacy and safety inthe acute treatment Cell Signaling inhibitor end in the secondary prevention of VTE.The RE-COVER trial evaluated dabigatran for 6 month treatmentof acute symptomatic VTE, even though the RE-MEDY andthe RE-SONATE trials are recruiting individuals who have beensuccessfully treated with common doses of an approved anticoagulantfor three to six months or who have completed6 to 18 months of treatment with vitamin K antagonist forconfirmed acute symptomatic VTE, respectively. The RECOVERstudy was published at the end of 2009. Patientswith acute VTE, DVT and/or PE, who had been initially treatedwith parenteral anticoagulants, had been randomized to receivedabigatran etexilate, administered at a dose of 150 mg twicedaily, or dose adjusted warfarin.
The primary outcome with the study wasthe 6-month incidence of recurrent symptomatic, objectivelyconfirmed VTE and related deaths. Thirty with the 1,274dabigatran individuals, as compared with 27 with the 1,265warfarin individuals, had recurrent VTE. The difference in riskwas 0.4 percentage points. The hazard ratio fgf inhibitor with dabigatran was 1.10. Big bleeding episodes occurredin 20dabigatran individuals and in 24warfarin individuals, and episodes of any bleeding had been observedin 205dabigatran individuals and in 277warfarinpatients.2. Direct element Xa inhibitorsRivaroxaban could be the first of this new class of drugs. It isa potent and selective oral Aspect Xa inhibitor with a particularchemical structure in its active-site binding region thatplays a role in the oral absorption with the drug, with a relativelyhigh bioavailabity.
Plasma levels of thedrug peak after 3 to 4 hours, with a mean half-life rangingfrom 5 to 9 hours in young individuals, and from 11 to13 hours in the elderly. The main VEGF route of excretionis renal, but the drug is also expelled through the faecal/biliarroute. Rivaroxaban can be administered at a fixed dosein any patient and doesn't require laboratory monitoring.Also rivaroxaban has been licensed in the European Unionand in Canada for the prevention of VTE in individuals undergoinghip- and knee-replacement surgery, with a recommendeddose of 10 mg when daily.Two phase II, dose-finding studies compared rivaroxabanadministered at total daily doses ranging from 20 mg to60 mg with common therapy with LMWH followed by oralvitamin K antagonists.
Based on the good resultsof these studies, the following doses had been selected for furtherinvestigation in the three phase III clinical trials aimed toassess the acute phase and fgf inhibitor the long term treatment Cell Signaling inhibitor of DVTand PE: 15 mg bid for 3 weeks followedby 20 mg qd in the ongoing Einstein DVT and EinsteinPE studies, in which individuals with objectively confirmed,symptomatic DVT or PE are randomized to treatment withrivaroxaban alone or with LMWH and vitamin K antagonistsfor a total period of 3 to 12 months, and 20 mg qd in theEinstein Extension study, in which individuals who had completed6 to 12 months of anticoagulant treatment with eithervitamin K antagonists or rivaroxabanafter an acute episode of VTE wererandomized to rivaroxaban or placebo for further 6 to12 months.
The Einstein Extension study is already completed,as well as the outcomes happen to be presented at the AmericanSociety of Hematology meeting in December 2009. Inthis randomised, double blind, placebo-controlled study, theprimary efficacy outcome was the recurrence of symptomaticVTE fgf inhibitor as well as the principal safety outcome was the occurrenceof key bleeding. In the course of treatment, symptomatic recurrentVTE events occurred in 7.1% individuals treated with placeboand in 1.3% individuals treated with rivaroxaban. Following stoppingthe study medication, 1.0% symptomatic recurrent VTEevents occurred in both groups during the a single month observationalperiod of stick to up. No key bleeding eventswere documented in the group of individuals treated with placebo,4major bleeding events occurred in the rivaroxabangroup. None of these bleeding events werefatal or occurred in a critical web-site. Clinically relevant non-majorbleeding occurred in 1.2% and in 5.4% individuals randomizedto placebo and rivaroxaban, respectively. Twopatients in the placebo group and 1patient
