التداخل بين فوسامبرينافير وسوزيتريجين

Concomitant use of JOURNAVX with strong CYP3A inhibitors is contraindicated [see Warnings and Precautions (5.1) , Drug Interactions (7.1) ] .

Concomitant use with strong CYP3A inhibitors is contraindicated.

Concomitant use of JOURNAVX with strong CYP3A inhibitors is contraindicated [see Drug Interactions (7.1) , Clinical Pharmacology (12.3) ] .

Strong and Moderate CYP3A inhibitors : Concomitant use with strong CYP3A inhibitors is contraindicated.

Increased Risk of Adverse Reactions with Concomitant Use with Strong or Moderate CYP3A Inhibitors Strong and moderate CYP3A inhibitors increase suzetrigine and M6-SUZ (active metabolite) exposures which may cause JOURNAVX adverse reactions.

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.
