DICUMAROL vs HEPARIN SODIUM 2,000 UNITS IN DEXTROSE 5% IN PLASTIC CONTAINER
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), Xa, and others, 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.
25,000 units in 250 mL D5W (100 units/mL) continuous IV infusion at 20,000-40,000 units/24 hours; adjust based on aPTT.

24–48 hours; prolonged in hepatic impairment or with CYP2C9 polymorphisms.
30-150 minutes (dose-dependent, saturable); mean 60-90 min. Prolonged in hepatic/renal impairment and pulmonary embolism.
Primarily renal as inactive metabolites; minimal biliary/fecal. ~95% renal, ~5% fecal.
Primarily renal (40-60% as unchanged drug) and reticuloendothelial system; small amount biliary/fecal. Clearance is saturable.
