HEPARIN LOCK FLUSH vs LIQUAEMIN SODIUM PRESERVATIVE FREE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin potentiates the activity of antithrombin III, inactivating thrombin and activated factor X (FXa), thereby preventing fibrin formation and thrombus propagation.
Heparin binds to antithrombin III, accelerating its inhibition of coagulation factors IIa (thrombin) and Xa, thereby preventing thrombus formation and extension.
10-100 units/mL solution, 1-2 mL flush intravascularly after each catheter use or daily when catheter is not in use; typical adult dose: 10-100 units per flush.
Intravenous: Initial bolus of 80 units/kg followed by continuous infusion at 18 units/kg/hour; subcutaneous: 5000 units every 8-12 hours.

Terminal elimination half-life approximately 1-2 hours (mean 1.5 hours) at therapeutic doses; increases with dose; in renal failure, half-life prolonged up to 3-5 hours; clinical note: duration of effect short due to rapid clearance, requiring continuous infusion or frequent dosing.
Terminal elimination half-life: 1-2 hours (0.5-1.5 h at therapeutic doses, dose-dependent due to saturable clearance). Context: shorter half-life in pulmonary embolism, prolonged in hepatic/renal impairment. Protamine reversal used for rapid offset.
Primarily renal via glomerular filtration and tubular secretion; about 50% excreted unchanged in urine; remainder metabolized in the liver and reticuloendothelial system (heparinase); fecal elimination negligible (<5%).
Renal: 50-70% as unchanged heparin and metabolites via saturable clearance; biliary/fecal: <5% as metabolites.
