Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides caloric support and is metabolized to carbon dioxide and water, yielding energy. Sodium chloride provides electrolyte replacement and maintains osmotic pressure.
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. Adult dose is typically 100-200 mL/hour, adjusted based on fluid and electrolyte needs, serum glucose, and 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 has an effective half-life of approximately 1.5-2 hours for equilibration with total body water; however, the terminal elimination half-life is not applicable as it is rapidly metabolized. Sodium has a elimination half-life of about 24-48 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.
The dextrose is metabolized to carbon dioxide and water, with negligible renal excretion of unchanged dextrose. Sodium and chloride are excreted renally, with >90% of an administered sodium load eliminated via kidneys within 24-48 hours in patients with normal renal function.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
