Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose 5% provides calories and fluid for hydration; sodium chloride 0.2% replaces sodium and chloride ions to maintain electrolyte balance; potassium chloride 20 mEq replaces potassium to maintain intracellular ion concentrations and nerve/muscle 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 at a rate of 100-125 mL/hour, providing 5 g dextrose, 0.2 g sodium chloride, and 20 mEq potassium chloride per liter. Typical adult dose is 1 L every 8-12 hours, adjusted for electrolyte needs and fluid status.
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: ~2 hours for glucose; Sodium and chloride: not applicable; Potassium: ~12 hours (terminal) in normokalemia, prolonged in renal impairment.
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, not excreted unchanged. Sodium and chloride are excreted renally; potassium is excreted renally (90%) and fecally (10%).
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
