Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides a source of calories and carbohydrate for metabolism; sodium and chloride are major electrolytes that maintain osmotic pressure and acid-base balance; potassium is essential for nerve impulse transmission, muscle contraction, and cardiac 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. Dose depends on patient's fluid, electrolyte, and caloric needs. Typical adult: 1000-2000 mL/day at 1-4 mL/min. Rate should not exceed 10 mL/min. Potassium content is 20 mEq/L; maximum potassium infusion rate is 10-20 mEq/h, not to exceed 240 mEq/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: 1.5-2.5 hours for exogenous glucose clearance. Potassium: terminal half-life 7-12 hours in normal renal function. Sodium: no defined half-life; body content regulated by renal excretion.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Renal: D-glucose is completely reabsorbed under normal conditions; excess is excreted unchanged. Potassium is primarily excreted by the kidneys (90%), with minor fecal (10%) loss. Sodium is predominantly excreted renally (95%), with small amounts via sweat and feces (5%). Chloride follows sodium excretion.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
