HEPARIN SODIUM 20,000 UNITS AND DEXTROSE 5% IN PLASTIC CONTAINER vs SAVAYSA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin binds to antithrombin III, accelerating its inhibition of thrombin (factor IIa) and activated factor X (Xa), thereby preventing fibrin formation. Dextrose 5% provides caloric support.
Direct inhibitor of factor Xa, thereby decreasing thrombin generation and fibrin clot formation.
IV: Initial bolus 80 units/kg, then continuous infusion at 18 units/kg/hr; adjust based on aPTT. Typical concentration: 20,000 units heparin in 500 mL D5W (40 units/mL).
5 mg orally twice daily for nonvalvular atrial fibrillation; 5 mg orally twice daily for venous thromboembolism treatment after initial parenteral anticoagulation for 5-10 days.

30–150 minutes (mean 90 min) for continuous IV infusion; shorter with higher doses due to saturable clearance. Prolonged in hepatic or renal impairment.
Terminal elimination half-life is 10-14 hours; in healthy subjects, mean half-life is approximately 10 hours. Clinically, this supports once-daily dosing. Half-life is prolonged in renal impairment (e.g., up to 17 hours in severe renal impairment).
Renal: negligible at therapeutic doses; hepatic metabolism to uroheparin and low molecular weight species; biliary/fecal: minimal. Clearance is dose-dependent and saturable.
Eliminated primarily via renal excretion of unchanged drug (approximately 82% of an oral dose is excreted in urine as edoxaban). Fecal/biliary excretion accounts for about 8%. Minor metabolism (<10%) via hydrolysis (mediated by carboxylesterase 1) and conjugation, with metabolites excreted renally or in feces.
