Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Heparin binds to antithrombin III, accelerating its inactivation of thrombin (factor IIa) and factor Xa, thereby inhibiting coagulation.
Magnesium sulfate provides magnesium ions, which are essential for various physiological processes. It acts as a cofactor for enzymatic reactions, stabilizes excitable membranes, and antagonizes calcium entry at the neuromuscular junction, leading to reduced acetylcholine release and muscle relaxation. In the CNS, it may act as a noncompetitive antagonist of NMDA receptors, exerting anticonvulsant effects.
5,000 units IV bolus, followed by continuous IV infusion of 18 units/kg/hr (initial based on actual body weight) for treatment of venous thromboembolism; or 5,000 units subcutaneously every 8-12 hours for prophylaxis of deep vein thrombosis. Titrate to aPTT 1.5-2.5 times control.
1 to 4 g intravenously as a 5% to 20% solution, rate not exceeding 150 mg/min; dosing frequency depends on indication (e.g., preeclampsia/eclampsia: 4-5 g IV loading then 1-2 g/hr infusion; hypomagnesemia: 1-2 g IV over 1-2 hours, may repeat based on serum magnesium levels).

Terminal half-life: 1-2 hours (dose-dependent; mean 1.5 hours). Clinical context: Prolonged in hepatic/renal insufficiency; obesity (increased Vd). IV bolus: 30-60 min; continuous infusion: 1-2 hours.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Renal: 40% as unchanged drug; reticuloendothelial system (liver, spleen): 60% metabolized to low molecular weight forms, then renally eliminated.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
