التداخل بين فوسامبرينافير ونابروكسين وإيزوميبرازول

Fosamprenavir calcium/ritonavir: ↔ Amprenavir ↔ Esomeprazole Sedative/hypnotics: Midazolam, triazolam ↑Midazolam ↑Triazolam Coadministration is contraindicated due to potential for serious and/or life-threatening reactions such as prolonged or increased sedation or respiratory depression [see Contraindications (4)].

Proton pump inhibitors: Esomeprazole a , lansoprazole, omeprazole, pantoprazole, rabeprazole Fosamprenavir calcium: ↔ Amprenavir ↑ Esomeprazole Proton pump inhibitors can be administered at the same time as a dose of fosamprenavir calcium with no change in plasma amprenavir concentrations.

• Decreased exposure of some antiretroviral drugs (e.g., rilpivirine, atazanavir, and nelfinavir) when used concomitantly with esomeprazole magnesium may reduce antiviral effect and promote the development of drug resistance [see Clinical Pharmacology (12.3) ].

• Increased exposure of other antiretroviral drugs (e.g., saquinavir) when used concomitantly with esomeprazole magnesium may increase toxicity [see Clinical Pharmacology (12.3) ].

CYP2C19 or CYP3A4 Inhibitors Clinical Impact : Increased exposure of esomeprazole [see Clinical Pharmacology (12.3) ].

Antiretrovirals Clinical Impact : The effect of esomeprazole magnesium on antiretroviral drugs is variable.

• There are other antiretroviral drugs which do not result in clinically relevant interactions with esomeprazole magnesium.
