Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose 5% provides free water and calories for cellular metabolism, with glucose being the primary energy source. Sodium chloride 0.33% restores sodium and chloride ions to maintain extracellular fluid osmolality and acid-base balance. Potassium chloride 0.075% replenishes potassium, essential for nerve conduction, muscle contraction, and enzymatic reactions.
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. Dose determined by fluid, electrolyte, and caloric requirements. Typical adult dose: 500-1000 mL as a single infusion at a rate of 100-200 mL/hour, based on clinical 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: <15 minutes (rapid cellular uptake and metabolism). Electrolytes: sodium and chloride have no defined half-life due to rapid distribution and renal regulation; potassium half-life approximately 1-1.5 hours in plasma following intravenous administration.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Dextrose: nearly completely metabolized to CO2 and water, with <1% excreted unchanged in urine. Sodium and chloride: primarily excreted renally, with >90% of filtered load reabsorbed; excretion varies with dietary intake and homeostatic mechanisms. Potassium: >90% excreted renally, with the remainder in feces and sweat.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
