Fluticasone propionate (interaction with ritonavir): in a clinical study where ritonavir 100 mg capsules bid were co-administered with 50 µg intranasal fluticasone propionate (4 times daily) for 7 days in healthy subjects, the fluticasone propionate plasma levels increased significantly, whereas the intrinsic cortisol levels decreased by approximately 86% (90% confidence interval 82-89%).
Flutikasoonpropionaat (koostoime ritonaviiriga): kliinilises uuringus, milles ritonaviiri 100 mg kapsleid (kaks korda ööpäevas) manustati koos 50 μg intranasaalse flutikasoonpropionaadiga (4 korda ööpäevas) seitsme päeva jooksul tervetele isikutele, tõusis flutikasoonpropionaadi plasmatase märkimisväärselt, samal ajal kui endogeense kortisooli tase vähenes ligikaudu 86% (90% usaldusintervall 82… 89%).
