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.
Competitive antagonist of histamine at the H2 receptor on gastric parietal cells, reducing gastric acid secretion (basal and stimulated).
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).
300 mg IV every 6-8 hours, or as a continuous IV infusion of 37.5 mg/hour (900 mg/day) for patients unable to take oral therapy.

Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Terminal elimination half-life: approximately 2 hours in healthy adults; prolonged in renal impairment (up to 20 hours in anuria).
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
Renal: 70% unchanged via glomerular filtration and tubular secretion. Biliary/fecal: minor (approximately 10-15% as metabolites).
