JYLAMVO vs MEXATE-AQ
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
JYLAMVO (methotrexate) is a folate analog that inhibits dihydrofolate reductase (DHFR), thereby disrupting DNA synthesis and repair. It also inhibits purine and thymidylate synthesis, leading to immunosuppressive and antineoplastic effects.
Methotrexate is a folate analog that inhibits dihydrofolate reductase (DHFR), blocking the conversion of dihydrofolate to tetrahydrofolate, which is required for the synthesis of purines and pyrimidines. This leads to inhibition of DNA, RNA, and protein synthesis, particularly in rapidly dividing cells. It also has immunosuppressive effects via inhibition of T cell activation and reduction of inflammatory cytokines.
Oral: 30 mg twice daily for adults with relapsed or refractory acute myeloid leukemia (AML) as a monotherapy.
Methotrexate: 7.5-25 mg orally once weekly for rheumatoid arthritis; 30-40 mg/m2 IV weekly for mycosis fungoides; 50-75 mg/m2 IV over 4-6 hours weekly for osteosarcoma; 15-20 mg/m2 IM weekly for psoriasis.

Terminal elimination half-life is 12-16 hours in adults with normal renal function; prolonged to 24-48 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is approximately 3–10 hours for low doses (<30 mg/m²) and 8–15 hours for high doses (>80 mg/m²). Prolonged to 48–72 hours in patients with third-space effusions or renal impairment.
Primarily renal elimination as unchanged drug (approximately 70-80%) with minor biliary/fecal excretion (20-30%).
Renal excretion predominates (80-90% as unchanged drug) via glomerular filtration and active tubular secretion. Biliary/fecal elimination is minor (<10%).
