Abstract

L'invention concerne une méthode de traitement de la thrombose chez des mammifères consistant à administrer des quantités thérapeutiquement efficaces d'une combinaison (i) d'un inhibiteur du facteur Xa et (ii) d'un composé choisi dans le groupe constitué d'aspirine, de TPA, d'un antagoniste de GPIIb/IIIa, d'héparine à faible masse moléculaire et d'héparine. Concernant au moins un parmi (i) et (ii), la dose administrée est une dose subthérapeutique. De préférence, la combinaison de (i) et de (ii) produit un effet synergique.
