Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides a source of calories and hydration, preventing ketosis and promoting glycogen deposition. Sodium chloride maintains extracellular fluid volume and electrolyte balance.
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.
Adult: Intravenous infusion at a rate determined by clinical condition, typically 100-200 mL/hour for maintenance; maximum infusion rate 25 g/hour (500 mL/hour). Dose individualized based on fluid, electrolyte, and glucose needs.
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).

Dextrose: <15 minutes due to rapid cellular uptake and metabolism; sodium and chloride: no defined half-life as electrolytes are homeostatically regulated.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Renal; dextrose is metabolized to CO2 and water; sodium and chloride are excreted renally with >90% reabsorption under normal conditions.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
