12. Clinical Pharmacology
Mechanism of Action

Dasatinib is a kinase inhibitor that inhibits BCR-ABL, SRC family kinases (SRC, LCK, YES, FYN), c-KIT, EPHA2, and PDGFRβ. It binds to multiple conformations of ABL kinase, including both active and inactive forms, making it effective against many imatinib-resistant BCR-ABL mutations (except T315I). Dasatinib achieves 325-fold greater potency against unmutated BCR-ABL compared to imatinib in vitro.

Pharmacokinetics

Tmax: 0.5-6 hours. Half-life: 3-5 hours. Protein binding: 96%. Metabolized primarily by CYP3A4. Excreted in feces (85%) and urine (4%). Steady-state by Day 7.
