Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin binds to antithrombin III, inducing a conformational change that accelerates the inactivation of thrombin (factor IIa) and activated factor X (Xa), thereby inhibiting coagulation.
Magnesium sulfate causes decreased release of acetylcholine at the neuromuscular junction, reducing muscle contractility. It also blocks calcium channels, leading to vasodilation and anticonvulsant effects.
IV infusion: Initial bolus 80 units/kg, then continuous infusion at 18 units/kg/hr. Adjust based on aPTT. Subcutaneous: 5,000-10,000 units every 8-12 hours.
IV: 1-4 g as a 10-20% solution, rate not exceeding 1 g/min; for eclampsia: 4-5 g IV bolus then 1-2 g/hour IV infusion.

1.5 hours (dose-dependent and increases with higher doses; e.g., 2.5 hours after 25,000 units IV; prolonged in hepatic or renal impairment)
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Renal (clearance primarily via reticuloendothelial system and liver, with minimal renal excretion of intact heparin; metabolites eliminated renally; <5% excreted unchanged in urine)
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
