Flurbiprofen (CAS 5104-49-4) is a member of phenylalkanoic acid derivative group of nonsteroid anti-inflammatory drugs. It exhibits anti-inflammatory, analgesic and antipyretic activities. Two different tablets containing flurbiprofen (FLU) were investigated in 24 healthy volunteers to prove the bioequivalence between both treatments after single oral dose administrations. Fluroben (R) 100 mg tablet and 100 mg tablet of the originator product were used as test and reference preparation respectively. The study was performed open label, randomized, two period cross-over design with 15 days wash out period. Blood samples were taken up to 24 hours for pharmacokinetic profiling. The plasma concentrations of flurbiprofen were determined with validated HPLC-UV method. Maximum plasma concentration (C-max) of FLU 19 143.65 ng/ml and 19 164.22 ng/ml were found for test and reference formulation respectively. Areas under the plasma concentration time curve AUC(0-infinity) of 118 501.4 ng.h/ml and 111 339.8 ng.h/ml were calculated test and reference formulation respectively. Primary target parameters AUC(0-infinity), and C-max, both of them were tested parametrically by analysis of variance (ANOVA); 90% confidence intervals were between 100.5%-111.18% for AUC(0-infinity). and 87.6%-115.0% for C-max. All these values were within the acceptance range (80%-125%) for bioequivalence studies.
