Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Linezolid is an oxazolidinone antibiotic that inhibits bacterial protein synthesis by binding to the 50S ribosomal subunit, preventing formation of the 70S initiation complex.
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.
600 mg IV every 12 hours for 10-14 days.
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).

Terminal elimination half-life is approximately 5.5 hours; in patients with severe renal impairment (CrCl <30 mL/min), half-life may be prolonged to 7-8 hours.
Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Renal excretion accounts for approximately 30% of the dose as unchanged drug; nonrenal clearance (likely hepatic metabolism) accounts for about 70%. Fecal excretion is minimal (<2%).
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
