Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inulin is a polysaccharide that is not absorbed from the gastrointestinal tract and is used as a diagnostic agent to measure glomerular filtration rate (GFR) by renal clearance. Sodium chloride provides electrolyte supplementation.
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.
Inulin: 5 g IV bolus followed by continuous infusion at 1.5 mL/min of a 10 g/L solution for GFR measurement. Sodium chloride: 0.9% solution as diluent.
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).

Normal renal function: 1.5 hours (range 1–2 h); decreases to 0.5 h with severe renal impairment; used to measure glomerular filtration rate (GFR)
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Renal: 100% as unchanged drug via glomerular filtration without tubular reabsorption or secretion; biliary/fecal: negligible (<1%)
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
