Argatroban is a direct thrombin inhibitor indicated: For prophylaxis or treatment of thrombosis in adult patients with heparin-induced thrombocytopenia (HIT) ( 1.1 ) As an anticoagulant in adult patients with or at risk for HIT undergoing percutaneous coronary intervention (PCI) ( 1 .2 ) 1.1 Heparin-Induced Thrombocytopenia Argatroban Injection is indicated for prophylaxis or treatment of thrombosis in adult patients with heparin-induced thrombocytopenia (HIT). 1.2 Percutaneous Coronary Intervention Argatroban Injection is indicated as an anticoagulant in adult patients with or at risk for HIT undergoing percutaneous coronary intervention (PCI).

Argatroban is contraindicated in Patients with major bleeding [ see Warnings and Precautions ( 5.1 ) ]. Patients with history of hypersensitivity to argatroban. Airway, skin, and generalized hypersensitivity reactions have been reported [ see Adverse Reactions ( 6.1 ) ]. Major bleeding ( 4 ) History of hypersensitivity to this product ( 4 )

Hemorrhage can occur. Unexplained fall in hematocrit or blood pressure may indicate hemorrhage. ( 5.1 ) Hepatic impairment: Adjust starting dose and titrate carefully in patients with HIT who have moderate or severe hepatic impairment. Avoid use in PCI in patients with clinically significant hepatic impairment. ( 5.2 ) 5.1 Risk of Hemorrhage Hemorrhage can occur at any site in the body in patients receiving argatroban. Unexplained fall in hematocrit or blood pressure may indicate hemorrhage. Intracranial and retroperitoneal hemorrhage [ see Adverse Reactions ( 6.1 ) ] has been reported. The risk of hemorrhage with argatroban may be increased in severe hypertension, immediately following lumbar puncture, spinal anesthesia, major surgery (especially involving the brain, spinal cord, or eye), hematologic conditions associated with increased bleeding tendencies such as congenital or acquired bleeding disorders, and gastrointestinal lesions such as ulcerations. Concomitant use of argatroban with antiplatelet agents, thrombolytics, and other anticoagulants may increase the risk of bleeding. 5.2 Use in Hepatic Impairment When administering argatroban to patients with hepatic impairment, start with a lower dose and carefully titrate until the desired level of anticoagulation is achieved. Achievement of steady state aPTT levels may take longer and require more argatroban dose adjustments in patients with hepatic impairment compared to patients with normal hepatic function [ see Use …

8.1 Pregnancy Risk Summary Limited data from published literature and postmarketing reports do not suggest an association between argatroban and adverse fetal developmental outcomes. There are risks to the mother associated with untreated thrombosis in pregnancy and a risk of hemorrhage in the mother and fetus associated with use of anticoagulants ( see Clinical Considerations ). In animal reproduction studies, there was no evidence of adverse developmental outcomes with intravenous administration of argatroban during organogenesis in rats and rabbits at doses up to 0.3- and 0.2-times, respectively, the maximum recommended human dose (MHRD) ( see Data ). The estimated background risk of …
