Novos anticoagulantes para a profilaxia do tromboembolismo venoso em cirurgias ortopédicas de grande porte

Abstract: ResumoApós cerca de 50 anos de experiência com a heparina e antagonistas da vitamina K (AVK), pesquisas e estudos com novos anticoagulantes vêm evoluindo de forma crescente nos últimos anos. Embora consagrados pelo uso, os anticoagulantes tradicionais têm limitações importantes em termos de controle laboratorial, complicações, efeitos colaterais, interações com medicamentos e dieta. A heparina não fracionada (HNF) tem interação com proteínas plasmáticas e parede vascular, pode desencadear trombocitopenia induz… Show more

“…Similar safety and effectiveness standards were obtained with rivaroxaban in VTE prophylaxis during major hip and knee surgeries, also using both the American and the European regimens, in four large-scale studies collectively referred to as RECORD (see comment in Yoshida et al 1 ). Moreover, rivaroxaban showed effective results in the treatment of VTE in the EINSTEIN studies (compared with conventional treatment with enoxaparin and warfarin) 5 .…”

“…Marcos Arêas Marques* For about five decades, vitamin K antagonists (VKA) were the only oral anticoagulants available for the treatment and prophylaxis of venous thromboembolism (VTE) 1 . The already known pharmacodynamic and pharmacokinetic limitations of this class of drugs fostered research into the development of new anticoagulant molecules, with similar effectiveness but presenting the following "theoretically ideal" characteristics: single daily dose oral administration; wide therapeutic window; rapid onset of action; no need for regular laboratory monitoring; predictable pharmacokinetics and pharmacodynamics; fast reversibility in case of bleeding (with antidote); limited food and drug interactions; and a low cost 2 .…”

“…Three clinical trials, namely RE-Novate, RE-Model and RE-Mobilize, evaluated dabigatran use in both the European (40 mg/day) and American (30 mg every 12 hours) regimens in cases of major hip and knee surgeries, and their results were not inferior to those obtained with enoxaparin for DVT prevention. 18 …”

“…17 Os resultados dos ensaios clínicos RE-Novate, RE-Model e RE-Mobilize avaliaram o uso da dabigatrana, tanto no regime europeu (40 mg/dia) e americano (30 mg a cada 12 horas), nas cirurgias de grande porte do quadril e joelho e mostraram resultados não inferiores àqueles obtidos com a enoxaparina para prevenção da TVP. 18 A apixabana é um inibidor do fator Xa. A dose sugerida é de 2,5 mg duas vezes por dia, começa 12 a 24 horas após a operação, continuada durante 12 dias ( AE 2) após ATJ e 35 dias ( AE 3) após artroplastia total de quadril.…”
