Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study assesses the effects of voriconazole, 200 mg, administered twice daily (BID), on the steady-state pharmacokinetics of atazanavir administered as atazanavir/ritonavir, 300/100 mg once daily (QD), in healthy participants with functional CYP2C19 alleles. The study also reviews the effects of atazanavir/ritonavir, 300/100 mg QD, on the pharmacokinetics of voriconazole, 200 mg, BID in healthy participants with functional CYP2C19 alleles.

Voriconazole

Intervention Type DRUG

Treatment A: Participants with functional CYP2C19 alleles (EM) received oral tablets of voriconazole, 400 mg, twice daily (BID), on Day 1, then 200 mg BID on Days 2 and 3.

Atazanavir/ritonavir dose was administered in the morning within 5 minutes of completing a light meal, and 1 hour before voriconazole morning dose. Treatment E: PM participants received atazanavir/ritonavir, 300/100 mg QD plus voriconazole, 100 mg BID, on Day 21, then 50 mg BID on Days 22-30.
