Resumo
Itraconazole increases venetoclax exposure and risks tumor lysis syndrome during dose initiation, as well as neutropenia and other toxicities. The risk is greatest during the ramp-up phase.
O que esta interação significa em palavras simples
Itraconazole and Venetoclax are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.

Por que acontece
Strong CYP3A4 inhibition (and P-glycoprotein inhibition) by itraconazole reduces venetoclax clearance.
O que fazer
