Resumo
Posaconazole can raise cabozantinib exposure because cabozantinib is cleared partly by CYP3A4. Higher levels may increase toxicities such as diarrhea, hypertension, hand-foot syndrome and bleeding.
O que esta interação significa em palavras simples
Cabozantinib and Posaconazole 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.
Cabozantinib belongs to Oncology; Posaconazole belongs to Anti Fungals.
Por que acontece
Strong CYP3A4 inhibition by posaconazole reduces the metabolic clearance of cabozantinib.
O que fazer
Prefer an antifungal or other agent without strong CYP3A4 inhibition. If it cannot be avoided, lower the cabozantinib dose per labeling, monitor for adverse effects, and restore the prior dose a few days after stopping posaconazole.
