Summary

Ivosidenib is metabolized by CYP3A4, and strong inducers like barbiturates lower its exposure. This may reduce antileukemic efficacy. Labeling advises avoiding strong CYP3A4 inducers.

What this interaction means in plain words

Ivosidenib and Secobarbital 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.

Ivosidenib belongs to Oncology; Secobarbital belongs to Central Nervous System.

Why it happens
