Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides a source of calories and energy, preventing protein catabolism and ketosis. Sodium chloride maintains osmotic pressure and fluid balance. Potassium chloride replenishes potassium and maintains intracellular ion gradients.
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; rate and volume determined by patient's fluid, electrolyte, and caloric needs. Typical adult maintenance: 100-125 mL/hour (2-3 L/day) of D5 0.2% NaCl with 0.15% KCl (20 mEq KCl/L) administered via continuous IV infusion.
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 (endogenous substrate, rapidly cleared via metabolism). Potassium: Terminal elimination half-life ~12-24 hours in healthy individuals, prolonged in renal impairment. Sodium and chloride: No defined half-life; renal excretion is regulated by homeostatic mechanisms.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Renal: Dextrose is completely metabolized to CO2 and water; only trace amounts excreted unchanged (<2%). Sodium and chloride are primarily excreted renally, with >90% of filtered load reabsorbed; excess is excreted in urine. Potassium is predominantly excreted renally (90%), with minor fecal (10%) loss. Biliary excretion is negligible.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
