Data are mean values ± SD. Visit A, flurbiprofen 50 mg alone; visit B, flurbiprofen 50 mg + fluconazole 400 mg; and visit C, flurbiprofen 50 mg after 7 days fluconazole 400 mg daily. AUC∞, area under the plasma concentration–time curve extrapolated to infinity; CL/F, total clearance; 4OHCLf, 4′-hydroxyflurbiprofen formation clearance; FGCLf, sum of flurbiprofen glucuronide formation clearance and flurbiprofen renal clearance; FLRR, flurbiprofen recovery ratio = 4′-OHF/4′-OHF+ F; FLMR, flurbiprofen metabolic ratio = 4′-OHF/F.
There were no statistically significant differences in the comparison between visit B and visit C.
Comparison between visit B or visit C and visit A: P < 0.001.
Comparison between visit B or visit C and visit A: P < 0.05.
