The purpose of the present study was designed to evaluate the bioequivalence of two ofloxacin tablets, Tarivid (Jeil Pharm. Co., Ltd.) and Favid (ILHWA Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). Twenty-four normal male volunteers, $23.67{\pm}3.12$ year in age and $68.50{\pm}7.23$ kg in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After four tablets containing 100 mg of ofloxacin were orally administered, blood was taken at predetermined time intervals and concentrations of ofloxacin in plasma were determined using HPLC. Pharmacokinetic parameters such as $AUC_t$, $C_{max}$ and $T_{max}$ were calculated and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$ and $C_{max}$ and untransformed $T_{max}$. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals for the log transformed data were acceptance range of log 0.8 to log 1.25 (e.g., $log0.94{\sim}log1.04\;and\;log0.90{\sim}log1.07\;for\;AUC_t\;and\;C_{max}$, respectively). The major parameters, $AUC_t$, and $C_{max}$, met the criteria of KDFA for bioequivalence indicating that Favid tablet is bioequivalent to Tarivid tablet.
