Summary
Primidone is metabolized to phenobarbital, which induces CYP3A4 and may lower nilotinib levels. This may reduce antileukemic efficacy.
What this interaction means in plain words
Nilotinib and Primidone 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.
Nilotinib belongs to Oncology; Primidone belongs to Central Nervous System.
Why it happens
CYP3A4 induction by primidone and its metabolite phenobarbital increasing nilotinib metabolism.
