Due to the development of new dosage forms and the improvement or pharmaceutics, the pharmaceutical excipients have become more specified and diverse, and the reclassification on them became necessary. Also with the increasing interests on the kinds and usage amount, related provisions, and evaluation of the pharmaceutical excipients, the systemic and effective control of them was in its demand. Therefore, in this research, we provided the following information on excipients: the type, amount and specification. In order to provide the information, we investigated, analysed and summarized the excipients that are approved by KFDA and published $ulcorner$Handbook of Pharmaceutical Excipients$lrcorner$). This handbook is expected to be used as a reference in the development of the pharmaceutics and evaluation in them. As the importance of excipients in pharmaceutics are increasing, IPEC which consist of IPEC-America, IPEC-Europe and JPEC, PDG and ICH have tried to make an international harmonization on excipient. This current status was not an exception to Korea, therefore, the result of this research is expected to make a progress in the evaluation on the excipients to an advanced level.
