Summary
Stiripentol inhibits and induces several CYP enzymes and may inhibit P-gp, so dexamethasone exposure may change unpredictably. Dexamethasone is also a CYP3A4 inducer that may lower stiripentol levels. With ophthalmic use the systemic effects are small.
What this interaction means in plain words
Dexamethasone-tobramycin and Stiripentol have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Dexamethasone-tobramycin belongs to Anti Bacterial; Stiripentol belongs to Central Nervous System.
Why it happens
Mixed CYP3A4 inhibition and induction and possible P-gp inhibition by stiripentol altering dexamethasone disposition.
What to do
No change is needed with ophthalmic use. With systemic dexamethasone, monitor for steroid effects and seizure control, and adjust doses as needed.
