Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides caloric support and corrects hypoglycemia; sodium chloride replaces sodium and chloride ions to maintain electrolyte balance; potassium chloride replaces potassium for maintenance of normal cellular 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.
Intravenous infusion, typical adult dose: 1000-2000 mL per 24 hours, rate adjusted based on fluid and electrolyte status. Potassium chloride content provides 15 mEq per liter; infusion rate should not exceed 10-20 mEq/hr potassium.
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: rapid, <15 min (physiologic turnover); Potassium: 6-8 h (intracellular redistribution phase); Sodium: prolonged, 24-48 h (dependent on renal function).
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Glucose is metabolized to carbon dioxide and water; potassium is primarily eliminated renally (90-95%) with minor fecal loss; sodium and chloride are excreted renally according to homeostasis.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
