التداخل بين سيكليسونيد وفوسامبرينافير

Coadministration of fluticasone and fosamprenavir calcium/ritonavir is not recommended unless the potential benefit to the patient outweighs the risk of systemic corticosteroid side effects.

Corticosteroid: Dexamethasone ↓ Amprenavir Use with caution.

Inhaled/nasal steroid: Fluticasone Fosamprenavir calcium: ↑ Fluticasone Use with caution.

Systemic corticosteroid effects including Cushing’s syndrome and adrenal suppression have been reported during postmarketing use in patients receiving ritonavir and inhaled or intranasally administered fluticasone.

In a drug interaction study, co-administration of orally inhaled ciclesonide and oral ketoconazole, a potent inhibitor of cytochrome P450 3A4, increased the exposure (AUC) of des-ciclesonide by approximately 3.6-fold at steady state, while levels of ciclesonide remained unchanged.
