Mechanism of Action

Heparin binds to antithrombin III, accelerating its inhibition of thrombin (factor IIa) and factor Xa, leading to anticoagulation.

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.

Clinical Dosing

Continuous IV infusion: Initial bolus 80 units/kg, then 18 units/kg/hour; adjust based on aPTT. Typical infusion rate: 1000-2000 units/hour for adults.

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).
