Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides caloric supplementation and serves as a source of glucose for cellular metabolism. Sodium chloride provides electrolytes for maintenance of fluid 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.
Intravenous infusion; typical adult dose is 1000-2000 mL per day, rate dependent on clinical condition and fluid status; maximum infusion rate usually 5 mL/kg/hour.
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 has a plasma half-life of approximately 1-2 hours; sodium and chloride have half-lives that depend on renal function and hydration status, typically 6-12 hours for sodium. In clinical context, half-life is not typically used for fluid and electrolyte replacement.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Dextrose and sodium chloride are endogenous substances. Dextrose is metabolized to CO2 and water; excess is excreted renally as glucose. Sodium and chloride are primarily excreted renally, with minimal biliary/fecal elimination. Nearly 100% of infused sodium and chloride are eliminated renally under normal conditions.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
