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, causing a conformational change that accelerates the inactivation of thrombin (factor IIa) and factor Xa. This inhibits fibrin formation and prevents clot propagation. Dextrose 5% provides a source of calories and fluid.
5000 IU subcutaneously twice daily for prophylaxis; 5000 IU intravenous bolus followed by 800-1000 IU/hour continuous intravenous infusion for treatment.
For therapeutic anticoagulation in adults, heparin is administered intravenously as an initial bolus of 80 units/kg followed by a continuous infusion of 18 units/kg/hour, with dose adjustment based on activated partial thromboplastin time (aPTT) targeting 1.5-2.5 times control. The concentration of heparin sodium 25,000 units and dextrose 5% in plastic container is typically used for continuous infusion at a rate calculated to deliver the prescribed units per hour.

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.
Terminal elimination half-life: 1-2 hours (dose-dependent, prolonged with higher doses due to saturable clearance). In hepatic or renal impairment: 1.5-3 hours. Clinical context: Twice-daily dosing may not maintain therapeutic levels; monitoring aPTT is essential.
Primarily renal, with 40-60% of the dose excreted unchanged in urine. Minor biliary/fecal elimination (<10%).
Renal: 40-50% as unchanged heparin (saturable); reticuloendothelial system: partial metabolism to uroheparin (less active); fecal: minimal (<5%).
