O que esta interação significa em palavras simples
Chloramphenicol and Cobimetinib 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.
Chloramphenicol belongs to Anti Bacterial; Cobimetinib belongs to Oncology.
Por que acontece
Chloramphenicol inhibits CYP3A4-mediated metabolism of cobimetinib, a CYP3A substrate.
