Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides a source of calories and hydration. Sodium chloride and potassium chloride replace extracellular fluid and electrolytes.
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 requirements; typical adult dose is 1000-2000 mL per 24 hours, infused at a rate of 50-100 mL/hour.
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.

Not applicable as a primary pharmacokinetic parameter for this combination; dextrose follows glucose disposition with a half-life of approximately 1-2 hours in euglycemic individuals, prolonged in diabetes. Electrolytes distribute and are eliminated with functional half-lives reflecting renal handling (e.g., potassium half-life ~6-8 hours).
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, with negligible renal elimination of unchanged glucose unless hyperglycemia exceeds renal threshold. Sodium and chloride are primarily excreted renally, with >90% of filtered sodium reabsorbed; potassium is predominantly excreted renally (90%) with minor fecal loss (<10%) under normal renal function.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
