ABSTRACT
Re-evaluation of bioequivalence of generic drugs is one of the key research focus currently. As a means to ensure consistency of the therapeutic effectiveness of drug products, clinical bioequivalence has been widely accepted as a gold standard test. In vitro dissolution testing based on the theory of the BCS is the best alternative to in vivo bioequivalence study. In this article, the conventional dissolution method and flow-through cell method were used to investigate the dissolution profiles of domestic amoxicillin capsules in different dissolution media, and the absorption behavior of the drugs with different release rates (t85% = 15-180 min) in the gastrointestinal tract was predicted by Gastro Plus. The flow-through cell method was thought better to reflect the release characteristics in vivo, and amoxicillin capsules with regard to the release rates up to 45 min (t85% = 45 min) were having a satisfied bioequivalence with the oral solution according to the C(max) and AUC. Although two different dissolution profiles of domestic amoxicillin capsules were found by flow-through cell methods, prediction results revealed that domestic capsules were probably bioequivalent to each other.
