Interaction entre Atazanavir et Hydrocortisone

Coadministration of fluticasone propionate and REYATAZ with ritonavir is not recommended unless the potential benefit to the patient outweighs the risk of systemic corticosteroid side effects [see Warnings and Precautions (5.1) ] .

Corticosteroids: dexamethasone and other corticosteroids (all routes of administration) ↓ atazanavir ↑ corticosteroids Coadministration with dexamethasone or other corticosteroids that induce CYP3A may result in loss of therapeutic effect of REYATAZ and development of resistance to atazanavir and/or ritonavir.

Alternative corticosteroids should be considered.

Coadministration with corticosteroids (all routes of administration) that are metabolized by CYP3A, particularly for long-term use, may increase the risk for development of systemic corticosteroid effects including Cushing’s syndrome and adrenal suppression.

Consider the potential benefit of treatment versus the risk of systemic corticosteroid effects.

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).
