Clinical Overview
Rivaroxaban is an oral, direct, and selective competitive factor Xa inhibitor (DOAC) on the WHO Model List of Essential Medicines. By blocking factor Xa, it interrupts both intrinsic and extrinsic coagulation cascades, preventing thrombin generation and clot propagation. Indicated for stroke prevention in non-valvular atrial fibrillation, treatment and prevention of deep vein thrombosis (DVT) and pulmonary embolism (PE), and CAD/PAD risk reduction (in combination with aspirin).
