Mechanism of Action

Anticoagulant: binds to antithrombin III, enhancing its inhibition of factor Xa and thrombin; also inactivates factors IX, XI, XII, and plasmin.

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: 12-18 units/kg/hour, adjusted based on aPTT. Initial bolus of 60-80 units/kg may be given. Typical infusion rate for prophylaxis: 5,000 units subcutaneously every 8-12 hours.

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).
