A Once-Daily, Oral, Direct Factor Xa Inhibitor, Rivaroxaban (BAY 59-7939), for Thromboprophylaxis After Total Hip Replacement

Abstract: Background-Rivaroxaban (BAY 59-7939)-an oral, direct Factor Xa inhibitor-could be an alternative to heparins and warfarin for the prevention and treatment of thromboembolic disorders. Methods and Results-This randomized, double-blind, double-dummy, active-comparator-controlled, multinational, dose-ranging study assessed the efficacy and safety of once-daily rivaroxaban relative to enoxaparin for prevention of venous thromboembolism in patients undergoing elective total hip replacement. Patients (nϭ873) were ra… Show more

“…During the development of the oral anticoagulants for prevention of VTE in THR and TKR surgery, multiple phase II dose‐finding trials and phase III trials have typically been conducted for the different types of surgery and comparator dose regimens 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38. The results of the current analyses suggest that the outcome of a single study in one type of surgery with one comparator dose regimen, used in conjunction with the model‐based meta‐analysis, would be sufficient to determine the optimal dose for both types of surgery and compared with both regimens of comparator.…”

“…Estase venosa pode ocorrer como resultado do posicionamento do membro durante o procedimento, do edema pós-operatório localizado, da mobilidade reduzida após a cirurgia e da redução substancial do fluxo venoso dos membros inferiores no transoperató-rio (1)(2)(3)14) . A lesão do endotélio pode ocorrer como resultado do posicionamento e da manipulação do membro inferior na mesa cirúrgica ou da reação térmica causada pela cimentação dos componentes da próte-se (13) .…”

“…Os antagonistas da vitamina K, apesar de administrados por via oral, apresentam início de ação lento, alta variabilidade entre a resposta dos pacientes à droga, necessidade de monitorização laboratorial freqüente, para evitar superdosagens, além de potencial interação com outras drogas (2,(18)(19) . Por sua vez, ambas as heparinas necessitam ser administradas por via parenteral, o que poderia ser considerado um fator para diminuir a adesão ao tratamento, além do desconforto da via (4,14,(28)(29)(30)(31)(32)(33) . O rivaroxaban é um anticoagulante oral que age inibindo diretamente a ação do fator de coagulação X ativado (FXa) (14,(34)(35)(36)(37)(38) .…”
