LIQUAEMIN LOCK FLUSH vs LIQUAEMIN SODIUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin potentiates the activity of antithrombin III, thereby inactivating thrombin (factor IIa) and activated factor X (Xa), and preventing fibrin clot formation. It also inhibits factors IXa, XIa, and XIIa.
Heparin binds to antithrombin III, accelerating the inactivation of thrombin and factor Xa, thereby inhibiting coagulation cascade.
10-100 units/mL solution; flush intermittent intravenous catheters after each use with 1-5 mL; for central venous catheters, use 2-3 mL of 10 units/mL solution; for peripheral catheters, use 1-2 mL of 10 units/mL solution.
Initial adult dose: 5,000 units IV bolus, followed by continuous IV infusion at 1,000–2,000 units/hour; or 10,000–20,000 units subcutaneously every 12 hours. Dose adjusted based on aPTT.

1-2 hours (dose-dependent; prolonged with higher doses, renal impairment, or in elderly).
Mean 1.5 hours (range 1-2 hours) after IV administration; increases with dose (e.g., 25,000 U IV: ~2.5 h). Clinical context: nonlinear pharmacokinetics; half-life prolonged in hepatic or renal impairment.
Renal (predominantly via reticuloendothelial system and liver metabolism; unchanged drug excreted in urine).
Primarily renal (heparin is metabolized and excreted as uroheparin and other metabolites; up to 50% of administered dose appears in urine as unchanged heparin, but clearance is dose-dependent and nonlinear).
