BOSUTINIB vs ROZLYTREK
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.
Entrectinib is a potent inhibitor of tropomyosin receptor tyrosine kinases (TRK) A, B, and C, and also inhibits ROS1 and ALK. It blocks downstream signaling pathways including MAPK, PI3K/AKT, and PLCγ, leading to apoptosis and reduced tumor growth in cancers with NTRK or ROS1 fusions.

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 half-life approximately 24 hours; supports once-daily dosing, steady-state reached in ~5 days.
Primarily fecal (approx. 68% as unchanged drug and metabolites) and renal (approx. 25%, with <0.2% as unchanged drug in urine).
Primarily hepatic metabolism via CYP3A4; 63% of dose recovered in feces (mostly as metabolites), 18% in urine (9% unchanged).
