Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose is a monosaccharide that provides a source of calories and fluid for intravenous administration. It increases blood glucose levels and may cause diuresis via osmotic effects. Sodium chloride provides electrolyte replacement to maintain or restore intravascular volume and extracellular 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; typical adult dose is 100-200 mL/hour of D5 0.9% NaCl, adjusted based on fluid and electrolyte status, glucose monitoring, and clinical indication.
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).

Glucose: ~1.5–2 hours for metabolic clearance in euglycemic individuals; prolonged in renal impairment (adds renal excretion of glucose if threshold exceeded). Dextrose solution constituents (water, sodium, chloride) have no true half-life; water turnover half-life ~3–4 hours in adults.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Renal elimination of free water and electrolytes. Glucose is metabolized to CO2 and water; excess glucose not metabolized is excreted renally as glucose (glucosuria) when renal threshold exceeded. Sodium and chloride are excreted renally, with >90% of filtered sodium reabsorbed; chloride follows sodium. No biliary or fecal elimination of intact drug.
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
