Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides a source of calories and acts as a substrate for cellular metabolism, replenishing glucose stores. Sodium chloride provides electrolytes for maintenance of 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; adult dose is 500-1000 mL at a rate of 100-200 mL/hour; frequency depends on fluid and electrolyte needs; maximum rate up to 400 mL/hour in hypovolemic states.
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 terminal half-life; dextrose is rapidly cleared from circulation with a metabolic clearance rate of ~15-20 mg/kg/min under normal conditions. The half-life of infused glucose is approximately 15-30 minutes due to rapid cellular uptake and metabolism.
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 via glycolysis and the citric acid cycle; essentially eliminated as CO₂ (exhaled) and water (renal, insensible loss). Sodium and chloride are primarily excreted renally (95%) with minor fecal (<2%) and sweat losses.
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
