阿尼普酶药理作用

编辑
Classification: Thrombolytic enzyme
Action/Kinetics: Prepared by acylating human plasma derived from lys-plasminogen and purified streptokinase derived from group C beta-hemolytic streptococci. When prepared, anistreplase is an inactive derivative of a fibrinolytic enzyme although the compound can still bind to fibrin. Anistreplase is activated by deacylation and subsequent release of the anisoyl group in the blood stream. The production of plasmin from plasminogen occurs in both the blood stream and the thrombus leading to thrombolysis. Lyses thrombi obstructing coronary arteries and reduces the size of infarcts. t1/2: 70-120 min.

阿尼普酶适应症状

编辑
Management of AMI in adults, resulting in improvement of ventricular function and reduction of mortality. Treatment should be initiated as soon as possible after the onset of symptoms of AMI.

阿尼普酶用法用量

编辑
IV only: 30 units over 2-5 min into an IV line or vein as soon as possible after onset of symptoms.

阿尼普酶注意事项

Pregnancy Category: C
Contraindications: Use in active internal bleeding; within 2 months of intracranial or intraspinal surgery; recent trauma, including cardiopulmonary resuscitation; history of CVA; intracranial neoplasm; arteriovenous malformation or aneurysm; known bleeding diathesis; severe, uncontrolled hypertension; severe allergic reactions to streptokinase.
Special Concerns: Use with caution in nursing mothers. Safety and effectiveness have not been determined in children. NOTE: The risks of anistreplase therapy may be increased in the following conditions; thus, benefit versus risk must be assessed prior to use. Within 10 days of major surgery (e.g., CABG, obstetric delivery, organ biopsy, previous puncture of noncompressible vessels); cerebrovascular disease; within 10 days of GI or GU bleeding; within 10 days of trauma including cardiopulmonary resuscitation; SBP > 180 mm Hg or DBP > 110 mm Hg; likelihood of left heart thrombus (e.g., mitral stenosis with atrial fibrillation); SBE; acute pericarditis; hemostatic defects including those secondary to severe hepatic or renal disease; pregnancy; clients older than 75 years of age; diabetic hemorrhagic retinopathy or other hemorrhagic ophthalmic conditions; septic thrombophlebitis or occluded arteriovenous cannula at seriously infected site; clients on oral anticoagulant therapy; any condition in which bleeding constitutes a significant hazard or would be difficult to manage due to its location.
