Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin binds to antithrombin III, accelerating its inhibition of coagulation factors IIa (thrombin), Xa, and others, thereby preventing thrombus formation and extension.
Liquamar (phenprocoumon) is a vitamin K antagonist that inhibits the synthesis of vitamin K-dependent clotting factors II, VII, IX, and X in the liver by blocking the reduction of vitamin K to its active hydroquinone form.
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.
Initial: 0.5-1 mg/kg IV (not to exceed 2 mg). Maintenance: 0.5-2 mg IV q8-12h based on INR.

30-150 minutes (dose-dependent, saturable); mean 60-90 min. Prolonged in hepatic/renal impairment and pulmonary embolism.
The terminal elimination half-life of phenprocoumon is approximately 5 to 7 days (range 3-10 days). This long half-life results in sustained anticoagulant effect over days, requiring careful monitoring and dose adjustments.
Primarily renal (40-60% as unchanged drug) and reticuloendothelial system; small amount biliary/fecal. Clearance is saturable.
Phenprocoumon is excreted primarily via renal elimination as metabolites (approximately 60-70% of the dose), with about 20% excreted in feces via biliary elimination. Less than 1% is excreted unchanged in urine.
