HEPARIN SODIUM IN PLASTIC CONTAINER vs LIQUAEMIN LOCK FLUSH
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin binds to antithrombin III, inducing conformational change that accelerates its inhibition of thrombin (factor IIa), factor Xa, and other coagulation factors (IXa, XIa, XIIa).
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.
Initial IV bolus of 80 units/kg followed by continuous IV infusion of 18 units/kg/hour; dose adjusted based on aPTT. Typical infusion range 10-30 units/kg/hour. Subcutaneous route: 5000 units every 8-12 hours for prophylaxis.
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.

30-150 minutes (dose-dependent: 0.5-1.5 h at low doses, up to 2.5 h at high doses). Prolonged in hepatic or renal impairment.
1-2 hours (dose-dependent; prolonged with higher doses, renal impairment, or in elderly).
Renal (predominantly), with minor biliary/fecal elimination. Clearance is dose- and concentration-dependent due to saturable binding.
Renal (predominantly via reticuloendothelial system and liver metabolism; unchanged drug excreted in urine).
