Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides a source of calories and carbohydrate for metabolism, preventing ketosis and promoting protein-sparing. Sodium chloride provides electrolytes to maintain osmotic pressure and 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: rate determined by patient's fluid and electrolyte needs; typical maintenance dose 30-100 mL/hour for adults. 10% dextrose provides 340 kcal/L. 0.33% NaCl provides 51 mEq/L Na+.
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: ~2.3 hours (intracellular utilization). Sodium chloride: not applicable; electrolytes are regulated homeostatically. Clinically, dextrose's half-life reflects rapid cellular uptake.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Renal: nearly 100% as free water and electrolytes. Dextrose is completely metabolized to CO2 and water; no significant biliary or fecal elimination.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
