BOSUTINIB vs STIVARGA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Bosutinib is a tyrosine kinase inhibitor that inhibits the BCR-ABL kinase, including many imatinib-resistant mutations, and Src family kinases.
Multikinase inhibitor that inhibits VEGFR-1, -2, -3, PDGFR-α, PDGFR-β, FGFR-1, -2, TIE2, KIT, RET, RAF-1, and B-RAF.
400 mg orally once daily with food.
160 mg orally once daily for 3 weeks, followed by 1 week off (28-day cycle).

Terminal elimination half-life approximately 33 hours (range 22-60 hr) after oral administration, supporting once-daily dosing.
Clinical Note
moderateBosutinib + Digoxin
"The serum concentration of Digoxin can be increased when it is combined with Bosutinib."
Clinical Note
moderateBosutinib + Digitoxin
"Bosutinib may decrease the cardiotoxic activities of Digitoxin."
Clinical Note
moderateBosutinib + Deslanoside
"Bosutinib may decrease the cardiotoxic activities of Deslanoside."
Clinical Note
moderateBosutinib + Acetyldigitoxin
"Bosutinib may decrease the cardiotoxic activities of Acetyldigitoxin."
Terminal elimination half-life is approximately 30 hours (range 15-42 h) for regorafenib and 25-60 h for its active metabolites M-2 and M-5. Steady-state is reached within 2-3 weeks.
Primarily fecal (approx. 68% as unchanged drug and metabolites) and renal (approx. 25%, with <0.2% as unchanged drug in urine).
Approximately 51% fecal (as unchanged drug and metabolites), 19% renal (as metabolites, <1% unchanged).
