Elvitegravir, kobisistat, emtrisitabin ve tenofovir ve Hidrokortizon etkileşimi

Concomitant administration of inhibitors of CYP3A4 may lead to increases in serum concentrations of ALKINDI SPRINKLE and increase the risk of adverse reactions associated with the use of excessive doses.

Intervention: Concomitant use of CYP3A4 inhibitors may require a decrease in the ALKINDI SPRINKLE dose.

CYP3A4 Inhibitors : concomitant administration may require a decrease in the ALKINDI SPRINKLE dose.

Table 2 Drug Interactions with ALKINDI SPRINKLE CYP3A4 Inhibitors Clinical Impact: Hydrocortisone is metabolized by cytochrome P450 3A4 (CYP3A4).

Examples: Anti-fungals: itraconazole, posaconazole, voriconazole Antibiotics: erythromycin and clarithromycin Antiretrovirals: ritonavir Grapefruit juice CYP3A4 Inducers Clinical Impact: Hydrocortisone is metabolized by cytochrome P450 3A4 (CYP3A4).

Corticosteroids: e.g., betamethasone budesonide ciclesonide dexamethasone fluticasone methylprednisolone mometasone prednisone triamcinolone ↓ elvitegravir ↓ cobicistat ↑ corticosteroids Coadministration with oral dexamethasone or other systemic corticosteroids that induce CYP3A may result in loss of therapeutic effect and development of resistance to elvitegravir.

Consider alternative corticosteroids.

Coadministration with corticosteroids (all routes of administration) whose exposures are significantly increased by strong CYP3A inhibitors can increase the risk for Cushing's syndrome and adrenal suppression.

Alternative corticosteroids including beclomethasone and prednisolone (whose PK and/or PD are less affected by strong CYP3A inhibitors relative to other studied steroids) should be considered, particularly for long-term use.
