Rivaroxaban is a highly selective, oral drug that directly inhibits factor Xa. Through highly selective and competitive inhibition of free and bound factor Xa and prothrombin activity, prolong the activated partial thromboplastin time plate (PT) and prothrombin time (aPTT) in a dose-dependent manner, which can interrupt the coagulation waterfall The endogenous and exogenous pathways inhibit the production of thrombin and thrombosis. Rivaroxaban does not inhibit thrombin (activating factor Ⅱ), nor has it proven to have an effect on platelets
The essential difference between rivaroxaban and fondaparinux/heparin is that it does not require the participation of antithrombin III and can directly antagonize free and bound factor Xa; while heparin requires antithrombin III to function, and It has no effect on factor Xa in the prothrombin complex.
