Trends in the market for drug delivery devices categorized as combination drugs and medical devices and regulatory challenges for autoinjectors in Japan

Although a variety of drug delivery devices have been launched in recent years, few studies have comprehensively investigated the market trends of combination drugs and medical devices approved or certified in Japan and the regulatory challenges related to their approval. Among the drug delivery devices, autoinjectors are more convenient than traditional prefilled syringes and are designed with safety features to prevent needlestick accidents, allowing self-injection by patients. Therefore, autoinjectors have been incorporated into the treatment of various diseases and have shown significant growth among drug delivery devices.
