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 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.
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.
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.

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.
1-2 hours (dose-dependent; prolonged with higher doses, renal impairment, or in elderly).
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 (predominantly via reticuloendothelial system and liver metabolism; unchanged drug excreted in urine).
