DEXTROSE 5% AND SODIUM CHLORIDE 0.9% vs MAGNESIUM SULFATE IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose 5% provides a source of calories and fluid for hydration, preventing ketosis by providing a minimal carbohydrate source. Sodium chloride 0.9% supplies electrolytes and maintains osmotic pressure in extracellular fluid.
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 is 500-1000 mL as a single dose, administered at a rate determined by clinical condition (e.g., 100-200 mL/h for maintenance).
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.

Glucose has a plasma half-life of approximately 1.5-2.5 hours in normal individuals, reflecting rapid cellular uptake and metabolism. Sodium and chloride have no definable half-life as they are actively regulated; however, the half-life of infused sodium is approximately 2-4 hours depending on renal function.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Glucose is completely metabolized to CO2 and water; renal excretion of unchanged glucose is negligible (<1%) in normoglycemic patients. Sodium and chloride are primarily excreted renally (90-95% of infused load) with small fecal and sweat losses. In dextrose 5% and sodium chloride 0.9%, both components are eliminated renally; the dextrose is metabolized, not excreted unchanged.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
