Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Unfractionated heparin (UFH) potentiates antithrombin III (ATIII) activity, leading to inhibition of factor Xa and thrombin (factor IIa). It also binds to heparin cofactor II, inhibits platelet aggregation, and increases vascular permeability.
Heparin binds to antithrombin III, accelerating its inhibition of coagulation factors IIa (thrombin), Xa, and others, thereby preventing thrombus formation and extension.
5000 IU subcutaneously twice daily for prophylaxis; 5000 IU intravenous bolus followed by 800-1000 IU/hour continuous intravenous infusion for treatment.
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.

Terminal elimination half-life is approximately 1.5 hours (subcutaneous) after a 5000 IU dose. With therapeutic doses (e.g., 15,000 IU/24h), half-life may prolong to 2-3 hours. Clinical context: Half-life is dose-dependent and increases with heparin clearance saturation.
30-150 minutes (dose-dependent, saturable); mean 60-90 min. Prolonged in hepatic/renal impairment and pulmonary embolism.
Primarily renal, with 40-60% of the dose excreted unchanged in urine. Minor biliary/fecal elimination (<10%).
Primarily renal (40-60% as unchanged drug) and reticuloendothelial system; small amount biliary/fecal. Clearance is saturable.
