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) via its pentasaccharide sequence, enhancing ATIII-mediated inhibition of factor Xa and, to a lesser extent, factor IIa (thrombin). It preferentially inhibits factor Xa over thrombin (anti-Xa:anti-IIa ratio ~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 subcutaneous every 12 hours or 1.5 mg/kg subcutaneous once daily

2-3 hours (terminal half-life in healthy adults); prolonged in hepatic impairment and elderly.
4.5-7 hours after single subcutaneous dose; prolonged to 8-12 hours in renal impairment (CrCl <30 mL/min). Clinical context: maintains anti-Xa activity for 12 hours with once-daily dosing.
Renal: ~50% (10% as unchanged drug, 40% as inactive metabolites); Biliary/fecal: ~50% (primarily as metabolites).
Renal (40-60% as unchanged drug via glomerular filtration and saturable tubular reabsorption). Biliary/fecal: negligible (<10%).
