Terapêutica anticoagulante: Novos anticoagulantes orais

Abstract

O surgimento da varfarina, enquanto medicamento anticoagulante, veio solucionar em parte a profilaxia e o tratamento do tromboembolismo venoso. É uma terapia barata, porém tem desvantagens que são a necessidade de monitorização e o risco de hemorragia. A terapêutica anticoagulante foi facilitada pela descoberta e desenvolvimento dos novos anticoagulantes orais. Estes representam uma nova solução terapêutica, além de não necessitar de testes de monitorização, têm revelado menos efeitos hemorrágicos. Porém é fulcral, mais do que na terapêutica convencional com recurso à varfarina, uma elevada adesão à terapêutica, pois as consequências da não adesão são bem mais gravosas do que com a varfarina.Esta nova terapia não é elegível para todos os indivíduos. Para a sua utilização devem considerar-se todos os fatores relacionados com o doente para se realizar uma escolha criteriosa e direcionada da terapêutica anticoagulante em doentes de risco.O custo elevado, a curto prazo, continua a ser o grande motivo da não adesão. Mas quando se estuda os efeitos a longo prazo e se entendem as verdadeiras vantagens desta nova terapêutica em comparação com a varfarina, verifica-se que o benefício supera o custo. Por fim, importa ressalvar que a limitação quanto à existência de antídotos também começa a ser ultrapassada, uma vez que o dabigatrano já tem antídoto aprovado. E o apixabano e o rivaroxabano têm antídoto desenvolvido e aprovado, até à data, apenas nos Estados Unidos. Isto permite aumentar a segurança no uso dos novos anticoagulantes orais.Posto isto, importa conhecer as características de cada um dos anticoagulantes para se poder fazer um melhor ajuste da terapêutica.

The emergence of warfarin as na anticoagulante drug partially resolved the profilaxys and treatment of venous thromboembolism. It is a cheap terapy, but has its disadvantages, the need for monitoring or the risk of bleeding, this therapy was facilitated by the introduction of new oral anticoagulants. These represente a new therapeutic solution, in addition to not requiring monitoring tests have revealed fewer bleeding effects. However, i tis more importante than in conventional therapy with warfarin that get a high adherence to therapy, because the consequences of non-compliance imply far more severe consequences than in warfarin.This new anticoagulante therapy is not elible for all pacientes. For the use of this therapy, all factos related to the pacient should be considered in order to make a judicious and targeted choice of anticoagulante therapy in patients at risk.The high cost, in the short term, remains the major reason for non-adherence. But, once studied the long-term effects and understands the true advantages of this new therapy compared to warfarin, it turn out that the benefit outweighs the cost.Finally, it should be noted that the limitation of antidote also begins to be exceeded, since the dabigatran already has approved antidote. Apixaban and rivaroxaban have antidote developed, but only approved is use in the United States. This facts increases safety in the use of new oral anticoagulants.Having said this, it is importante to know the characteristics of each anticoagulante in order to make a better adjustment of the therapeutics choice.
