Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Low molecular weight heparin that potentiates antithrombin III, inhibiting factor Xa and factor IIa, thereby preventing thrombus formation.
Enoxaparin binds to antithrombin III (ATIII), accelerating its inhibition of coagulation factors Xa and IIa (thrombin). Its anti-factor Xa to anti-factor IIa activity ratio is approximately 3.6:1.
Embolectomy with intra-arterial streptokinase: 250,000 IU loading dose over 30 minutes followed by 100,000 IU/hour for up to 72 hours. Alternatively, mechanical thrombectomy without thrombolytic.
1 mg/kg subcutaneously every 12 hours or 1.5 mg/kg subcutaneously once daily. For prophylaxis: 40 mg subcutaneously once daily or 30 mg subcutaneously every 12 hours.

2-3 hours (terminal half-life in healthy adults); prolonged in hepatic impairment and elderly.
Terminal elimination half-life is 4.5 hours after subcutaneous administration based on anti-Factor Xa activity; prolonged to 6-7 hours in renal impairment (CrCl <30 mL/min).
Renal: ~50% (10% as unchanged drug, 40% as inactive metabolites); Biliary/fecal: ~50% (primarily as metabolites).
Renal excretion of anti-Factor Xa activity accounts for approximately 40% of total clearance; a small fraction undergoes biliary/fecal elimination (<10%).
