Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides calories for metabolic processes, restoring blood glucose levels and reducing protein and fat catabolism. Sodium chloride maintains osmolarity and replaces sodium and chloride losses.
Magnesium sulfate causes decreased release of acetylcholine at the neuromuscular junction, reducing muscle contractility. It also blocks calcium channels, leading to vasodilation and anticonvulsant effects.
Intravenous infusion. Adult: 500-1000 mL per dose at a rate of 2-6 mL/min, frequency dependent on fluid and electrolyte needs. Maximum 40 mL/kg/day.
IV: 1-4 g as a 10-20% solution, rate not exceeding 1 g/min; for eclampsia: 4-5 g IV bolus then 1-2 g/hour IV infusion.

Glucose half-life is approximately 1.5-2 hours in normal individuals, prolonged in renal impairment or diabetes. Sodium and chloride have no defined half-life as they are electrolytes; their elimination depends on renal function and hydration status.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Renal: >99% of administered glucose is metabolized or excreted; sodium and chloride are excreted renally. In dextrose 5% and sodium chloride 0.2%, glucose undergoes metabolism to CO2 and water; excess is excreted renally. Sodium and chloride are almost entirely excreted renally with >90% reabsorption under normal conditions.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
