Mechanism of Action

Bacteriostatic sodium chloride 0.9% is an isotonic solution used as a diluent or vehicle for medications. Sodium chloride provides osmotic balance and acts as a source of electrolytes. The bacteriostatic property is due to the presence of benzyl alcohol, which inhibits bacterial growth by disrupting bacterial cell wall synthesis and protein function.

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; typical adult dose is 1000 mL every 24 hours, administered at a rate of 50-100 mL/hour, to maintain intravascular volume and correct sodium deficiency.

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).
