Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides calories for metabolic processes, restoring blood glucose levels and reducing protein and fat catabolism. Sodium chloride maintains osmolarity and replaces sodium and chloride losses.
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.
Intravenous infusion. Adult: 500-1000 mL per dose at a rate of 2-6 mL/min, frequency dependent on fluid and electrolyte needs. Maximum 40 mL/kg/day.
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).

Glucose half-life is approximately 1.5-2 hours in normal individuals, prolonged in renal impairment or diabetes. Sodium and chloride have no defined half-life as they are electrolytes; their elimination depends on renal function and hydration status.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Renal: >99% of administered glucose is metabolized or excreted; sodium and chloride are excreted renally. In dextrose 5% and sodium chloride 0.2%, glucose undergoes metabolism to CO2 and water; excess is excreted renally. Sodium and chloride are almost entirely excreted renally with >90% reabsorption under normal conditions.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
