MYTREX A vs SULSOXIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Methotrexate inhibits dihydrofolate reductase, leading to depletion of tetrahydrofolate and inhibition of DNA synthesis and cell proliferation. Also has immunomodulatory effects via adenosine release.
Bactericidal; inhibits cell wall synthesis by binding to penicillin-binding proteins (PBPs) and disrupting peptidoglycan cross-linking.
Methotrexate (MYTREX A) 7.5-25 mg orally once weekly, or 15-25 mg intramuscularly/subcutaneously once weekly for rheumatoid arthritis; in oncology, dosing varies per protocol.
500 mg orally 4 times daily for 10-14 days (or 1 g orally 4 times daily for severe infections).

Terminal elimination half-life: 12-15 hours in normal renal function; prolonged to 24-30 hours in moderate to severe renal impairment (CrCl <30 mL/min).
8 hours (terminal) — extends in renal impairment (up to 24 hours in CrCl <30 mL/min); requires dose adjustment
Renal: 90% unchanged drug; fecal: <10% via bile; minor hepatic metabolism to inactive metabolites.
Renal: 70% (unchanged); biliary/fecal: 20%; minor hepatic metabolism (<10%)
