Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides calories and serves as a source of energy. Sodium chloride provides electrolytes to maintain osmolality and fluid balance.
Magnesium sulfate provides magnesium ions, which are essential for various physiological processes. It acts as a cofactor for enzymatic reactions, stabilizes excitable membranes, and antagonizes calcium entry at the neuromuscular junction, leading to reduced acetylcholine release and muscle relaxation. In the CNS, it may act as a noncompetitive antagonist of NMDA receptors, exerting anticonvulsant effects.
Intravenous infusion; rate determined by fluid and electrolyte needs; typical adult rate 100-200 mL/hour.
1 to 4 g intravenously as a 5% to 20% solution, rate not exceeding 150 mg/min; dosing frequency depends on indication (e.g., preeclampsia/eclampsia: 4-5 g IV loading then 1-2 g/hr infusion; hypomagnesemia: 1-2 g IV over 1-2 hours, may repeat based on serum magnesium levels).

Dextrose: not applicable (endogenous substrate). Sodium: 10-20 minutes (rapid distribution); chloride parallels sodium. Clinical context: renal function prolongs half-life of infused components.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Dextrose is metabolized to carbon dioxide and water; sodium and chloride are excreted renally. >90% of water and electrolytes are eliminated via kidneys. Minimal fecal or biliary elimination.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
