Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin binds to antithrombin III, accelerating its inhibition of coagulation factors IIa (thrombin), Xa, and others, thereby preventing thrombus formation and extension.
Heparin binds to antithrombin III, inducing a conformational change that accelerates the inactivation of thrombin (factor IIa) and factor Xa, thereby inhibiting coagulation.
25,000 units in 250 mL D5W (100 units/mL) continuous IV infusion at 20,000-40,000 units/24 hours; adjust based on aPTT.
Intravenous: Initial bolus of 80 units/kg (or 5000 units) followed by continuous infusion of 18 units/kg/h (or 1300 units/h), adjusted to maintain aPTT 1.5-2.5 times control. Subcutaneous: 5000 units every 8-12 hours for prophylaxis.

30-150 minutes (dose-dependent, saturable); mean 60-90 min. Prolonged in hepatic/renal impairment and pulmonary embolism.
0.5–2 hours (dose-dependent; at therapeutic doses, ~1–2 h; with higher doses, up to 2.5 h). Clinical context: shorter half-life in pulmonary embolism; prolonged in hepatic or renal impairment.
Primarily renal (40-60% as unchanged drug) and reticuloendothelial system; small amount biliary/fecal. Clearance is saturable.
Primarily cleared via reticuloendothelial system and metabolism; renal excretion of unchanged drug is minimal (<5%).
