Highest levels in liver, preputial gland and uveal tract, suggesting melanin binding; low CNS penetration
“Highest radioactivity tissue concentrations were in the liver and preputial gland in albino rats and in the uveal tract in the pigmented rats, suggesting melanin binding of brensocatib or its metabolites. There is low CNS penetration.”
