초록
The purpose of the present study was to evaluate the bioequivalence of meloxicam capsule, $Mobic^{TM}$ capsule( Boehringer Ingelheim Ltd., Korea) as a reference drug and $Meloxifen^{TM}$ capsule (Kukje Pharma Ind. Co., Ltd., Korea) as a test drug, according to the guidelines of Korea Food and Drug Administration(KFDA). Thirty two healthy male Korean volunteers received capsule containing meloxicam 7.5 mg in a $2{\times}2$ crossover study. There was a one-week above washout period between the doses. Plasma concentrations of meloxicam were monitored for over a period of 72 hr after administration by using a high performance liquid chromatography-tandem mass spectrometer(LC-MS/MS). $AUC_t$(the area under the plasma concentration-time curve from time zero to 72 hr), $C_{max}$(maximum plasma drug concentration) and $T_{max}$(time to reach $C_{max}$) were complied from the plasma concentration-time data. Analysis of variance(ANOVA) test was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$ and $C_{max}$. The 90% confidence intervals of the $AUC_t$ ratio and the $C_{max}$ ratio for $Meloxifen^{TM}/Mobic^{TM}$ were log 0.8605-log 0.9847 and log 0.9765-log 1.1503, respectively. These values were within the acceptable bioequivalence intervals of log 0.80-log 1.25, recommended by KFDA. In all of these results, we concluded that $Meloxifen^{TM}$ capsule was bioequivalent to $Mobic^{TM}$ capsule, based on the rate and extent of absorption.
