BOSUTINIB vs TASIGNA
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.
Nilotinib is a tyrosine kinase inhibitor that binds to and inhibits the activity of BCR-ABL, the constitutively activated fusion protein responsible for chronic myeloid leukemia (CML). It also inhibits other kinases including KIT, PDGFR, and DDR1.

Terminal elimination half-life approximately 33 hours (range 22-60 hr) after oral administration, supporting once-daily dosing.
Terminal elimination half-life is approximately 90-120 hours, supporting once-daily dosing.
Primarily fecal (approx. 68% as unchanged drug and metabolites) and renal (approx. 25%, with <0.2% as unchanged drug in urine).
Primarily fecal (approximately 66-93% of the dose) as unchanged drug and metabolites; renal excretion is minimal (<5% of the dose).
