Abstract:
The growth of healthcare cost is a serious issue in many countries. Generic drug products play an essential role in reducing healthcare costs because they are less costly than the innovator drug products. The regulatory review of generic drug products in Japan is conducted by the Pharmaceuticals and Medical Devices Agency (PMDA). This report introduces the activities of the PMDA from fiscal years 2014-2019. The number of approvals of new generic drug products and partial changes was trending downward. Alternatively, the PMDA conducted six types of consultation meetings to advise on development and application; the number of consultation meetings was increasing. Moreover, during this period, the Ministry of Health, Labour and Welfare issued two basic principles for ophthalmic dosage forms and dry powder inhaler drug products and revised the guidelines for bioequivalence. Finally, the future of generic drug product development and considerations to improve their regulation were discussed. More efforts will continue to enable a more efficient and rational generic drug product development and shortening of the review period for partial change approval.
