Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Meropenem is a carbapenem antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
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).
1 g IV every 8 hours infused over 15-30 minutes; dose range 0.5-2 g every 8 hours depending on infection severity

Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
1.0–1.5 hours in healthy adults; prolonged to 4–6 hours in moderate renal impairment (CrCl 30–50 mL/min) and 8–12 hours in severe renal impairment (CrCl <10 mL/min).
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
Renal: ~70% unchanged via glomerular filtration and tubular secretion; hepatic metabolism: ~20% via hydrolysis of beta-lactam ring; fecal: <2%.
