Tnkase

TNKase ® is indicated to reduce the risk of death associated with acute ST elevation myocardial infarction (STEMI). TNKase is a tissue plasminogen activator, indicated to reduce the risk of death associated with acute ST elevation myocardial infarction (STEMI). ( 1 )

TNKase is contraindicated in patients with [see Warnings and Precautions (5.1) ] : Active internal bleeding History of cerebrovascular accident Intracranial or intraspinal surgery or trauma within 2 months Intracranial neoplasm, arteriovenous malformation, or aneurysm Known bleeding diathesis Severe uncontrolled hypertension Active internal bleeding ( 4 ) History of cerebrovascular accident ( 4 ) Intracranial or intraspinal surgery or trauma within 2 months ( 4 ) Intracranial neoplasm, arteriovenous malformation, or aneurysm ( 4 ) Known bleeding diathesis ( 4 ) Severe uncontrolled hypertension ( 4 )

Bleeding: Increases the risk of bleeding. Avoid intramuscular injections. Monitor for bleeding. ( 5.1 ) Thromboembolism: The use of thrombolytics can increase the risk of thrombo-embolic events in patients with high likelihood of left heart thrombus. ( 5.2 ) Cholesterol Embolization: Has been reported in patients treated with thrombolytic agents. ( 5.3 ) Arrhythmias: It is recommended that anti-arrhythmic therapy for bradycardia and/or ventricular irritability be available when TNKase is administered.

( 5.4 ) Increased Risk of Heart Failure and Recurrent Ischemia when used with Planned Percutaneous Coronary Intervention (PCI) in STEMI: In patients with a large ST segment elevation myocardial infarction, physicians should choose either thrombolysis or PCI as the primary treatment strategy for reperfusion. Rescue PCI or subsequent elective PCI may be performed after administration of thrombolytic therapies if medically appropriate.

( 5.5 ) Hypersensitivity: Monitor patients treated with TNKase during and for several hours after infusion. If symptoms of hypersensitivity occur, initiate appropriate therapy (e.g., antihistamines, corticosteroids). ( 5.6 )

5.1Bleeding

TNKase can cause bleeding, including intracranial hemorrhage and fatal bleeding. Concomitant use of other drugs that impair hemostasis increases the risk of bleeding. Should serious bleeding that is not controlled by local pressure occur, discontinue any concomitant heparin or antiplatelet agents immediately and treat appropriately. Avoid intramuscular injections and nonessential handling of the patient for the first few hours following treatment with TNKase.
