Summary
Ceritinib inhibits CYP3A4 and can increase budesonide exposure, which is normally limited by extensive first-pass metabolism. Higher systemic levels can cause corticosteroid adverse effects such as Cushingoid features and adrenal suppression.
What this interaction means in plain words
Budesonide and Ceritinib 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.
Budesonide belongs to Respiratory; Ceritinib belongs to Oncology.
Why it happens
Inhibition of CYP3A4 reduces budesonide first-pass and systemic metabolism.
What to do
