Several good manufacturing practice (GMP) compliance issues and their associated quality problems that have been revealed since 2020 have led to large-scale recalls and supply suspensions of drug products in Japan. This paper provides an overview of the causes and countermeasures for supply disruptions of low-molecular-weight chemical pharmaceutical agents, focusing on quality-related issues. A recent increase in the use of generic drugs emphasized the importance of strengthening active pharmaceutical ingredient (API) supply chains and ensuring GMP compliance among drug manufacturers. In addition, increasing recalls in the drug products of certain marketing authorization holders due to storage stability problems strongly suggests the need to improve their development process considerably. Other measures to stabilize the supply of pharmaceuticals, including increasing stockpiles of APIs, were also discussed.

Particular batches of Moderna mRNA Coronavirus Disease 2019 (COVID-19) vaccine were recalled after foreign particles were found in some vaccine vials at the vaccination site in Japan in August 2021. We investigated the foreign particles at the request of the Ministry of Health, Labour and Welfare. Energy dispersive X-ray spectroscopy analysis suggested that the foreign particles found in the vials recalled from the vaccination sites were from stainless steel SUS 316L, which was in line with the findings of the root cause investigation by the manufacturer. The sizes of the observed particles ranged from <50 μm to 548 μm in the major axis. Similar foreign particles were also detected in 2 of the 5 vaccine vials of the same lot stored by the manufacturer, indicating that the foreign particles have already been administered to some people via vaccine. Observation of the vials of the same lot by digital microscope found smaller particles those were not detected by visual inspection, suggesting that more vials were affected. Contrarily, visual inspection and subvisible particulate matter test indicated no foreign particles in the vials of normal lots. Possible root cause and strategies to prevent such a deviation were discussed from technical and regulatory aspects.
