Loxoprofen sodium (sodium 2-[4-(2-oxocyclopentylmethyl)phenyl] propionate dehydrate) is a nonsteroidal antiinflammatory drug of α-phenyl propionic acid derivative. To test the bioequivalence of loxoprofen, the pharmacokinetic parameters of new preparation of loxoprofen, LENOX was compared with LOXONIN as a reference drug. Fourteen healthy volunteers were entered to the stydy (Yonsei University College of Medicine, Severance Hospital IRB approval No. 9608). They were administered 60 mg of loxoprofen in 2x2 cross-over design. There was one week of drug-free interval between doses. The blood sample was taken on schedule up to 8 hours, and the plasma concentration loxoprofen was measured by reverse phase high-performance liquid chromatography (HPLC) with UV-detector. There were no significant difference between two preparations when AUC, Cmax, and Tmax were compared by ANOVA. The mean differences of AUC, Cmax, and Tmax were within 20% of the reference drug: the values were 2.22,5.61, and 12.50%, respectively. The confidence limits of AUC and Cmax but not Tmax satisfied the bioequivalence criteria. These results suggest that the tested LENOX is bioequivalent to the reference drug.
