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 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 and volume determined by patient fluid and electrolyte needs, typically 1-2 L/day in adults.
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).

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.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
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 (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
