Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dextrose provides a source of calories and glucose, which is metabolized to carbon dioxide and water, yielding energy. Sodium chloride maintains fluid and electrolyte 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 maintenance dose is 1-2 L per 24 hours adjusted based on fluid and electrolyte needs. Rate determined by clinical condition.
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: variable, approximately 1-2 hours for plasma glucose in euglycemic state; sodium and chloride: 6-12 hours depending on renal function and hydration status.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Dextrose and sodium chloride are endogenous substances; excess dextrose is metabolized to CO2 and water, with negligible renal excretion of unchanged glucose; sodium and chloride are primarily excreted renally (over 90% of filtered load).
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
