The objective of this study was to provide guidelines for bioequivalence (BE) studies of 29 selected drugs of expiration of re-examination drugs in 2015-2016 and to investigate the comparative dissolution test for the international harmonization. Among these drugs, 29 drugs were selected based on the severity of adverse drug reaction which need Post Marketing Surveillance (PMS), the upcoming BE re-evaluation drugs and the expiration of the re-examination of drugs in 2016. For these 29 selected drugs, the documents of Ministry of Food and Drug Safety (MFDS), Food and drug administration, USA (FDA), regulatory agency of European Union, and Japan, and the published literatures from academia were searched. For 29 selected drugs, BE guidelines were prepared and they consisted of subject selection criteria (contraindication, precaution, adverse reaction, and drug-drug interaction etc), suggested dose regimen, bio-analytical method for plasma drug concentration, and published pharmacokinetic parameters of these drugs. In addition, for the development of generic drug formulation, comparative dissolution test has advantages, but has difference in the test solution, sampling time, similarity factor etc. Documents for comparative dissolution test was filed from Ministry of Food and Drug Safety (MFDS), Food and drug administration, USA (FDA), and regulatory agency of European Union, Japan, Canada, and WHO, and the published literatures from academia. And detailed condition for comparative dissolution among different countries was compared. BE guidelines for the selected 29 drugs can provide useful information for pharmaceutical companies and contract research organizations (CRO), and internationally harmonized comparative dissolution test may facilitated generic drug approval.
