Limited data in animals suggests possible prolonged elimination half-life of t-PA in patients with severely impaired hepatic function and/or hepatic blood flow. WebThe plasma half-life of alteplase is 3 to 4 min, with metabolism mainly by the liver (plasma clearance 550–680 ml/min). Total plasma clear-ance therefore occurs in approximately 40 min. Due to its relative fibrin sp ecificity, alteplase, at a dose of 100 mg, leads to a modest decrease of the circulating fibrinogen levels to about 60% at 4 h,
