التداخل بين فوسامبرينافير وميتابيفات

Strong CYP3A Inhibitors and Inducers: Avoid concomitant use.

Moderate CYP3A Inhibitors: Avoid concomitant use.

Prevention or Management Avoid co-administration of strong CYP3A inhibitors with AQVESME [see Dosage and Administration (2.4) ] .

Prevention or Management Avoid co-administration of moderate CYP3A inhibitors with AQVESME [see Dosage and Administration (2.4) ] .

Effect of Other Drugs on AQVESME Strong CYP3A Inhibitors Clinical Impact Co-administration of AQVESME with strong CYP3A inhibitors increased mitapivat plasma concentrations [see Clinical Pharmacology (12.3) ] .

Initiation of medications that inhibit or induce CYP3A may increase or decrease concentrations of fosamprenavir calcium/ritonavir, respectively.

Coadministration of fosamprenavir calcium with drugs that induce CYP3A4 may decrease amprenavir (active metabolite) concentrations leading to potential loss of virologic activity.

Coadministration of fosamprenavir calcium and drugs that induce CYP3A4, such as rifampin, may decrease amprenavir concentrations and reduce its therapeutic effect.

Data also suggest that amprenavir induces CYP3A4.

Ritonavir also appears to induce CYP3A, CYP1A2, CYP2C9, CYP2C19, and CYP2B6, as well as other enzymes, including glucuronosyl transferase.
