التداخل بين إيترافيرين وبريدنيزون

CYP 3A4 inducers and inhibitors: May, respectively, increase or decrease clearance of corticosteroids, necessitating dose adjustment.

CYP 3A4 Inducers (e.g., Barbiturates, Phenytoin, Carbamazepine, and Rifampin) Drugs such as barbiturates, phenytoin, ephedrine, and rifampin, which induce hepatic microsomal drug metabolizing enzyme activity may enhance the metabolism of corticosteroids and require that the dosage of the corticosteroid be increased.

Corticosteroid : dexamethasone (systemic) ↓ etravirine Systemic dexamethasone induces CYP3A and can decrease etravirine plasma concentrations.
