Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides caloric support, replenishes glycogen stores, and prevents ketosis by supplying glucose for cellular energy metabolism. Sodium chloride maintains osmotic balance and replaces extracellular fluid and electrolytes.
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 and volume determined by patient fluid and electrolyte needs, typically 1-2 L/day in adults.
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.

Exogenous dextrose has a plasma half-life of approximately 15–20 minutes under normal metabolic conditions; in hyperglycemia or insulin resistance, half-life is prolonged.
Normal renal function: 4–6 hours (terminal). In oliguria or anuria, half-life may extend to >24 hours, requiring dose adjustment.
Exogenous dextrose is fully metabolized to carbon dioxide and water; no significant renal or biliary excretion of intact dextrose. Sodium and chloride are primarily excreted renally (greater than 90% of filtered load reabsorbed; excess excreted in urine).
Primarily renal (glomerular filtration); >90% excreted unchanged in urine. Biliary/fecal elimination is negligible (<1%).
