Search Japan's register of prescription-drug package inserts. Narrows by generic or brand name, therapeutic class code, a term inside the insert's indications, warnings, contraindications or drug interactions, the marketing authorisation holder, and the date the insert was last updated. Every match carries the drug's generic and brand names, its marketing authorisation holder and distributors with their roles, the package insert's revision date and its PDF and XML links, and the links to the patient guide, interview form, risk management plan and its materials, the revision-instruction history and the review reports where the register publishes them.

How to use it

Names, indications and section terms must be written in Japanese — the register holds no English text, so `aspirin` matches nothing while `アスピリン` does. A query matching more than 1000 inserts returns a 412 rather than the first 1000, so narrow it with `therapeutic_class` or an exact `name_match` instead of raising `count`. `therapeutic_class` is the Japanese commodity classification, not ATC: three digits is one class and two digits its parent, and the parent groups are usually wide enough to hit that limit. One row is one package insert, and the same drug appears once per manufacturer, so generic molecules return dozens of near-identical rows. Some matches are aggregate entries for a substance with no current insert of its own — several brand names and companies in one row, carrying only a revision-history link — and those are not returned, so the register's own match count runs ahead of what this endpoint can hand back. Feed `id` to pmda/drugs/package_insert for the insert's structured text.
