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 thrombin (factor IIa) and factor Xa, thereby preventing thrombus formation and propagation.
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.
IV: Initial bolus of 5000 units followed by continuous infusion at 1300 units/hour, adjusted based on aPTT. Typical infusion range 1000-2000 units/hour.

24–48 hours; prolonged in hepatic impairment or with CYP2C9 polymorphisms.
30-60 minutes at therapeutic doses, dose-dependent (e.g., 100 U/kg yields t½ ~56 min; 400 U/kg yields ~152 min). At lower doses (e.g., 25 U/kg), t½ is ~30 min. Prolonged in hepatic or renal impairment.
Primarily renal as inactive metabolites; minimal biliary/fecal. ~95% renal, ~5% fecal.
Primarily renal; metabolism by hepatic and reticuloendothelial system desulfation yields uroheparin, which is excreted in urine. Unchanged heparin is also excreted renally, with elimination proportional to dose and molecular weight. Biliary/fecal excretion is negligible (<5%).
