Os antagonistas da vitamina K foram, durante mais de 50 anos, os únicos anticoagulantes orais disponiveis. A imprevisibilidade da farmacocinética e farmacodinâmica desta classe de fármacos, responsável pela dificuldade na sua utilização, conduziu à necessidade do desenvolvimento de novas moléculas anticoagulantes. Estão actualmente diponíveis os resultados dos estudos de novos anticoagulantes orais no tromboembolismo venoso e na fibrilhação auricular, que se revêem neste trabalho. For more than 50 years, vitamin K antagonists were the only oral anticoagulants available. The unpredictability of its pharmacokinetics and pharmacodynamics, responsible for its difficult clinical management, has raised the need of new anticoagulants. Results of trials involving the new anticoagulants in venous thromboembolism and atrial fibrillation are now available and reviewed in this paper.
