Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides glucose for cellular metabolism, replenishing energy stores and correcting hypoglycemia. Sodium chloride and potassium chloride restore electrolyte balance, maintaining osmolality and membrane potentials.
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. Typical adult dose: 1000 mL to 2000 mL per 24 hours, administered at a rate of 50-100 mL/hour, adjusted based on fluid and electrolyte status.
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). Potassium: Rapid distribution phase (1-1.5 h) with terminal half-life 12-24 h (dose-dependent due to intracellular uptake). Sodium and chloride: Governed by renal regulation, no true half-life.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Renal: Dextrose is metabolized to CO2 and water, not excreted unchanged. Sodium and chloride are excreted renally (90-95% of filtered load reabsorbed). Potassium is excreted renally (90% of daily intake, with 10% fecal).
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
