wing orthopedicsurgery also as in treating acute proximal DVT. Ineach study, the authors concluded that once-daily or twice-dailyrivaroxaban was as efficacious as normal therapy with similarsafety profiles.45–48 In 2009, however, the FDA sought moreinformation on this agent.RECORD. The REgulation of Coagulation in main CX-4945 Orthopedicsurgery reducing the Risk of DVT and PE program comprisesfour phase 4 clinical trials investigating the safety andefficacy of rivaroxaban as thromboprophylaxis in far more than12,000 individuals undergoing total hip or knee arthroplasty.49–52 In each study, rivaroxaban was given as 10 mgonce dailyand wascompared with either enoxaparin 40 mg SQ as soon as dailyor enoxaparin 30 mg SQ twice day-to-day.? RECORD 1 analyzed the thromboprophylaxis possible ofrivaroxaban following total hip replacement.
The resultsshowed a statistically considerable reduction within the total incidenceof VTEwith no differencein totalnon-majorbleeding.49? RECORD 2 evaluated the long-term prophylaxis of rivaroxabanversus the short-term prophylaxis of enoxaparinfollowing total hip replacement. When given for 31 to 39days, rivaroxaban was far more effectivethanenoxaparin given for 10 CX-4945 to 14 days. Although there was anincreased danger of bleeding within the rivaroxaban group, it wasnot considerable.50? RECORD 3 and RECORD 4 were conducted to assessVTE prophylaxis following total knee arthroplasty. InRECORD 3, there was a significantdecreasein VTE incidence when rivaroxaban was given for 10 to 14days versus enoxaparin, and main bleeding rates weresimilar among groups.
? In RECORD 4, rivaroxaban as soon as day-to-day was discovered to be superiorto enoxaparin twice dailyin VTE prophylaxisfollowing axitinib knee arthroplasty. Safety profiles weresimilar.52A prespecified pooled analysis of the RECORD programwas performed so as to decide whether there was aneffect on essential NSCLC clinical outcomes. The authors had postulatedthat the total number of events would be lower in theindividual trials. Outcomes of the analysis showed that once-dailyrivaroxaban, compared with enoxaparin, significantly improvedcomposite outcomes of symptomatic VTE, cardiovascularevents, all-cause mortality, and main bleeding events.53Patients receiving rivaroxaban had a 58% reduction in symptomaticVTE and all-cause mortalityfor the total treatment duration plus a 52% reduction in theactive treatment pool, with no significantincreased danger of main bleeding.
53In terms of adverse events, the RECORD program showeda nonsignificant elevation in hepatic enzymesin the rivaroxaban group.49–51Preliminary phase 1 studies reported nonsignificant incidencesof headache, diarrhea, fatigue, flatulence, and dizzinesswith rivaroxaban, but these effects were not quantified in latertrials.29 Interactions normally noticed with current anticoagulantsand axitinib medicines, such as digoxin, naproxen, aspirin, clopidogrel, and abciximabdo not affectrivaroxaban. Far more studies are needed to evaluate the effect offood as well as other drugs on rivaroxaban’s pharmacokinetics andpharmacodynamics.29EINSTEIN. Rivaroxaban is undergoing further phase 3clinical trials for added indications. For VTE treatment, theEinstein programis conducting threeadditional studies.
54 The DVT and PE trials CX-4945 are investigating rivaroxaban15 mg twice day-to-day for three weeks, followed by 20 mg oncedaily, versus enoxaparin 1 mg/kg twice day-to-day for at the least fivedays, followed by warfarin.The extension study compares rivaroxaban 20 mg day-to-day withplacebo for six to 12 months.27 When the PE study is ongoing,data from the DVT and extension studies have been published.In searching for the incidence of current VTE, the researchersnoted that rivaroxaban was non-inferior to enoxaparin– warfarinin the DVT study and superior toplaceboin the extension study.55ROCKET–AF. Rivaroxaban 20 mg dailyis being compared with warfarinfor stroke prevention in individuals with atrial fibrillation. This trialis scheduled to last a maximumof four years, depending on the occurrence of adverseevents.
27MAGELLAN. Rivaroxaban 10 mg day-to-day for 35 days wascompared with enoxaparin 40 mg day-to-day for 10 days in 8,000medically ill individuals.27 This trialhas been completed.ATLAS–ACS TIMI 51. Rivaroxaban 2.5 or 5 mg twice dailytaken for six months was compared with placebo for the preventionof post-ACS cardiac axitinib events.27 TheAnti-Xa Therapy toLower cardiovascular events in addition to aspirin with/withoutthienopyridine therapy in Subjects with Acute CoronarySyndrome–Thrombolysis in Myocardial Infarction trial iscompleted.ApixabanApixabanis an additional oral, direct aspect Xa inhibitorundergoing clinical trials for the prevention and treatmentof VTE, stroke prevention secondary to atrial fibrillation,and secondary prophylaxis in acute coronary syndromes.4The oral bioavailability of apixaban is 50% to 85%. Peak plasmaconcentrations are reached in three hours.The agent’s terminal half-life is eight to 15 hours, and it ismetabolized mainly through the CYP 450 isoenzyme 3A4. It isexcreted through the kidneysand feces.56–58 It
