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 fluid for intravenous administration. It increases blood glucose levels and may cause diuresis via osmotic effects. Sodium chloride provides electrolyte replacement to maintain or restore intravascular volume and extracellular fluid balance.
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 100-200 mL/hour of D5 0.9% NaCl, adjusted based on fluid and electrolyte status, glucose monitoring, and clinical indication.
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: ~1.5–2 hours for metabolic clearance in euglycemic individuals; prolonged in renal impairment (adds renal excretion of glucose if threshold exceeded). Dextrose solution constituents (water, sodium, chloride) have no true half-life; water turnover half-life ~3–4 hours in adults.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Renal elimination of free water and electrolytes. Glucose is metabolized to CO2 and water; excess glucose not metabolized is excreted renally as glucose (glucosuria) when renal threshold exceeded. Sodium and chloride are excreted renally, with >90% of filtered sodium reabsorbed; chloride follows sodium. No biliary or fecal elimination of intact drug.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
