Draft Guideline for Industry to Manage Drug Shortages in Japan.

The increasing global drug shortage poses a substantial challenge to national healthcare systems and affects access to essential therapies. In Japan, this problem is exacerbated by a large-scale government campaign to switch from brand-name products to generic drugs and manufacturing/marketing authorization holders with poor development and manufacturing controls. Regulatory bodies, such as the U.S. Food and Drug Administration and the European Medicines Agency have developed guidelines aimed at ensuring continuous drug supply and mitigating manufacturing risks. However, Japan's efforts have primarily relied on voluntary industry guidelines, lacking the robust regulatory frameworks of other developed nations. Therefore, this study proposes a draft guideline for Japan's pharmaceutical industry to manage drug shortages effectively. The Japanese government needs to establish a framework system that will enable pharmaceutical companies to effectively maintain a stable supply based on the proposals developed in this study.
