JYLAMVO vs PARAPLATIN
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.
Carboplatin, a platinum-based alkylating agent, forms interstrand and intrastrand DNA cross-links by binding to DNA guanine bases, inhibiting DNA replication and transcription, leading to cell cycle arrest and apoptosis.
Oral: 30 mg twice daily for adults with relapsed or refractory acute myeloid leukemia (AML) as a monotherapy.
360 mg/m2 IV every 3 weeks or area under the curve (AUC) 4-6 mg/mL/min IV every 3-4 weeks using Calvert formula.

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: 2.6-5.1 hours (initial phase), 22-52 hours (terminal phase) for total platinum; 1.3-2.1 hours for ultrafilterable platinum. Clinically, the terminal half-life reflects slow release of protein-bound platinum.
Primarily renal elimination as unchanged drug (approximately 70-80%) with minor biliary/fecal excretion (20-30%).
Renal excretion: ~70-90% of platinum is excreted in urine within 24 hours, primarily as unchanged drug. Fecal excretion: <6%. Biliary excretion: minimal.
