MIDOSTAURIN vs PONATINIB HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Midostaurin is a multikinase inhibitor that targets FLT3 (FMS-like tyrosine kinase 3), KIT, PDGFRα/β, VEGFR2, and PKC. It inhibits FLT3 receptor signaling and downstream MAPK/ERK and PI3K/AKT pathways, inducing apoptosis in FLT3-mutated cells.
Ponatinib is a potent oral tyrosine kinase inhibitor that inhibits BCR-ABL, including T315I mutant, as well as VEGFR, PDGFR, FGFR, and SRC kinases.
50 mg orally twice daily with food for acute myeloid leukemia (AML) with FLT3 mutation; for advanced systemic mastocytosis, 100 mg orally twice daily.
45 mg orally once daily with or without food.

The terminal elimination half-life (t½) of midostaurin is approximately 20 hours (range 17–22 h) for the parent drug and slightly longer for its active metabolite CGP52421 (~30 h). This supports twice-daily dosing while maintaining steady-state concentrations.
Clinical Note
moderateMidostaurin + Digoxin
"Midostaurin may decrease the cardiotoxic activities of Digoxin."
Clinical Note

"Midostaurin may decrease the cardiotoxic activities of Digitoxin."
Clinical Note
moderateMidostaurin + Deslanoside
"Midostaurin may decrease the cardiotoxic activities of Deslanoside."
Clinical Note
moderateMidostaurin + Acetyldigitoxin
"Midostaurin may decrease the cardiotoxic activities of Acetyldigitoxin."
Terminal half-life of approximately 29 hours (range 18–48 h) supporting once-daily dosing; steady-state reached within 7 days.
Midostaurin is primarily eliminated via feces (approximately 95% of total radioactivity after a single 50 mg oral dose), with <5% excreted in urine. Biliary excretion is the major route for fecal elimination; unchanged midostaurin accounts for <10% of the dose, with the remainder as metabolites.
Primarily hepatobiliary excretion; ~87% of dose recovered in feces (mostly as metabolites), <5% in urine as unchanged drug.
