Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides calories and serves as a source of glucose, which is utilized for cellular energy metabolism. Sodium chloride provides sodium and chloride ions to maintain electrolyte balance and osmotic pressure. Potassium chloride provides potassium ions essential for cellular functions, including nerve conduction and muscle contraction, and helps correct or prevent hypokalemia.
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: 1000-2000 mL/day (25-50 mL/kg/day) titrated to fluid and electrolyte needs; maximum infusion rate 0.5 g/kg/hour dextrose.
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.

Dextrose: not applicable as it is rapidly metabolized; glucose half-life is approximately 1.5-2 hours in normal individuals, prolonged in diabetes. Sodium and potassium: not defined as they are regulated by renal function.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Dextrose is metabolized to carbon dioxide and water; <1% excreted unchanged in urine. Sodium chloride and potassium chloride are excreted renally; >90% of filtered sodium and potassium is reabsorbed, with excretion balancing intake via renal regulation. Biliary/fecal excretion is negligible.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
