DICUMAROL vs LIQUAEMIN SODIUM PRESERVATIVE FREE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dicumarol is a vitamin K antagonist that inhibits the synthesis of vitamin K-dependent clotting factors (II, VII, IX, X) and anticoagulant proteins C and S by blocking the reduction of vitamin K epoxide to vitamin K hydroquinone in the liver.
Heparin binds to antithrombin III, accelerating its inhibition of coagulation factors IIa (thrombin) and Xa, thereby preventing thrombus formation and extension.
Initial oral dose 200-300 mg once daily for 2-3 days, then maintenance 25-200 mg once daily adjusted to target INR of 2.0-3.0 for most indications. Administered orally.
Intravenous: Initial bolus of 80 units/kg followed by continuous infusion at 18 units/kg/hour; subcutaneous: 5000 units every 8-12 hours.

24–48 hours; prolonged in hepatic impairment or with CYP2C9 polymorphisms.
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 as inactive metabolites; minimal biliary/fecal. ~95% renal, ~5% fecal.
Renal: 50-70% as unchanged heparin and metabolites via saturable clearance; biliary/fecal: <5% as metabolites.
