Mechanism of Action

Dextrose provides calories and serves as a source of glucose, which is metabolized to carbon dioxide and water, yielding energy. Sodium and chloride are major electrolytes that maintain osmolality and acid-base balance. Potassium is essential for nerve conduction, muscle contraction, and maintaining intracellular tonicity.

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

Intravenous infusion; dose determined by individual patient requirements, fluid and electrolyte status, serum potassium concentration, and acid-base balance; typical adult rate: 100-200 mL/hour (up to 2 L/day) as maintenance fluid.

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).
