Clinical considerations on the posology of direct oral anticoagulants. / Consideraciones clínicas sobre la posología de los anticoagulantes orales de acción directa.

The efficacy of dicoumarin anticoagulants has been shown in patients with nonvalvular atrial fibrillation. However, they have drawbacks such as the need to adjust the dosage and the interaction with drugs and food. Direct oral anticoagulants are an effective and safe alternative and have a less complicated clinical management. There is considerable debate on the selection criteria for the posology regimens of direct oral anticoagulants. The differences among them and their administration regimens have raised questions about the clinical, pharmacokinetic and pharmacodynamic selection criteria that support the posology. This review critically analyses the available evidence and its impact on the final selection of the dosage regimen.

Los anticoagulantes dicumarínicos han demostrado su eficacia en pacientes con fibrilación auricular no valvular. Sin embargo, presentan desventajas como la necesidad de ajustar la dosis y la interacción con fármacos y alimentos. Por su parte, los anticoagulantes orales de acción directa se presentan como una alternativa eficaz y segura con un manejo clínico menos complejo. Existe un considerable debate sobre los criterios de selección de las pautas posológicas de los anticoagulantes orales de acción directa. Las diferencias entre ellos y sus pautas de administración han despertado dudas sobre los criterios de selección clínicos, farmacocinéticos y farmacodinámicos que avalan dicha posología. Esta revisión analiza de forma crítica las evidencias disponibles y su impacto en la selección final del esquema posológico (AU)
