Inogatran is a synthetic thrombin inhibitor, developed for the possible treatment and prophylaxis of arterial and venous thrombotic diseases.
Inogatran (0.075, 0.25, 0.75 mg/kg, i.v.) results in dose-dependent increases in activated partial thromboplastin time (aPTT), thrombin time (TT), and prothrombin time (PT) in a canine electrolytic injury model of venous thrombosis[1]. Inogatran dose-dependently inhibits thrombus formation, which is measured as an increase in time to occlusion (TTO) and a decrease in thrombus weight. Inogatran also improves vena caval blood flow and reduces the overall incidence of thrombotic occlusion in a rat model[2].
