Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of histamine at H2 receptors on gastric parietal cells, reducing gastric acid secretion (basal and stimulated) by inhibiting cAMP production.
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.
300 mg intravenously every 6-8 hours or as continuous IV infusion at 37.5-50 mg/hour. Maximum 2400 mg/day.
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).

2-3 hours in normal renal function, prolonged to >8 hours in severe renal impairment (CrCl <20 mL/min).
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Renal (75% as unchanged drug via glomerular filtration and tubular secretion); hepatic metabolism (25%); fecal (<10%).
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
