Bioequivalence Assessment of Domperidone Maleate Tablets in Healthy Korean Volunteers

  • Published : 2003.06.01

Abstract

The bioequivalence of two tablet formulations of 12.72mg domperidone maleate (Sinil "$Perinal^{\circledR}$" tablets vs. Janssen Korea "Motilium-$M^{\circledR}$" tablets) was assessed in healthy Korean volunteers after oral administration in a randomized crossover study. Blood samples were collected at spccified time intervals, and plasma concentration was measured as the amount of domperidone base using a validated HPLC method. The pharmacokinetic parameters of $AUC_{0{\rightarrow}48},\; C_{max},\;T_{max}$ and $t_{1/2}$ were determined from plasma concentration-time profile of two formulations. Any significant statistical differences were not observed between these two formulations. On the evaluation of bioequivalence according to Korea Food and Drug Administration Guideline, 90% confidence limits after logmithmic transformation fell within the acceptable range (log 0.8∼log 1.25). Based on these data, it can be concluded that two domperidone maleate tablets showed comparable pharmacokinetic profiles, which means that the Sinil "$Perinal^{\circledR}$" tablet is bioequivalent to the Janssen Korea ""Motilium-M$^{\circledR}$".
