Summary
Elacestrant is a CYP3A4 substrate, and inducers reduce its exposure. Eslicarbazepine may therefore decrease its efficacy in breast cancer.
What this interaction means in plain words
Elacestrant and Eslicarbazepine 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.
Elacestrant belongs to Oncology; Eslicarbazepine belongs to Central Nervous System.
Why it happens
CYP3A4 induction by eslicarbazepine increases elacestrant clearance.
