Sintesi

Clarithromycin markedly raises bosutinib concentrations by inhibiting its CYP3A4 metabolism and P-glycoprotein efflux. This can cause hepatotoxicity, diarrhea, myelosuppression and QT effects.

Cosa significa questa interazione in parole semplici

Bosutinib and Clarithromycin can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Bosutinib belongs to Oncology; Clarithromycin belongs to Anti Bacterial.

Livello di evidenza: High

Perché avviene

Inhibition of CYP3A4 and P-glycoprotein reduces bosutinib clearance.
