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.
TepadinA (thiotepa) is an alkylating agent that crosslinks DNA, inhibiting DNA replication and transcription, leading to cell death. It is cell cycle phase-nonspecific.
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).
6.25 mg/m2 (based on ideal body weight) intravenously over 2 hours every 6 hours for 16 doses (total dose 100 mg/m2) as part of conditioning regimen prior to hematopoietic stem cell transplantation.

Terminal half-life approximately 4-5 hours in normal renal function; prolonged in renal impairment (up to 40 hours).
Terminal elimination half-life: 1.5–3.5 hours; clinically, the short half-life allows high-intensity dosing with stem cell support
Primarily renal (90-100% as unchanged magnesium). Less than 1% biliary/fecal.
Primarily renal; approximately 60-70% of the dose is excreted unchanged in urine within 24 hours; minor fecal elimination (<10%)
