Betrixaban (INN, codenamed PRT-054,021) is an anticoagulant drug which acts as a direct factor Xa inhibitor.[1] It is potent, orally active and highly selective for factor Xa, being selected from a group of similar compounds for its low hERG affinity.[2] Betrixaban has undergone human clinical trials for prevention of embolism after knee surgery,[3] and prevention of stroke following atrial fibrillation,[4] with promising results.[5] Betrixaban is currently being studied in a human clinical trial for extended duration thromboprophylaxis to prevent venous thromboembolism in acute medically ill patients.[6] Joint development with Portola was discontinued in 2011 by Merck.[7] Betrixaban is now being developed by Portola Pharmaceuticals.
