FDA has issued draft guidance outlining updated current good manufacturing practice (CGMP) standards for medical gases, including oxygen, nitrogen, nitrous oxide, carbon dioxide, helium, carbon monoxide, and medical air. The draft guidance, which revises a 2017 version, incorporates new rules codified in 21 CFR part 213 that specifically address the unique characteristics of medical gas production. Previously, medical gases were regulated under general CGMP rules for finished pharmaceuticals (parts 210 and 211).

Key recommendations in the draft include:

- Ensuring the reliability of suppliers and their processes.
- Protecting against container closure leaks.
- Proper cleaning and maintenance of manufacturing facilities and equipment.
- Preventing labeling errors and product mix-ups.
- Guidelines for stability and expiration testing, as well as handling returned or salvaged medical gases.

The guidance emphasizes the importance of establishing an effective pharmaceutical quality system, which enables manufacturers to assess risks in production and address them proactively, reflecting the FDA’s principle that quality should be built into the product, not just tested afterward.

The document also details quality unit responsibilities, requiring oversight of all components, materials, containers, labeling, and the final gas products. The guidance allows for flexibility in staffing, recognizing that smaller manufacturers may have one person serving multiple roles, while larger companies may have dedicated corporate quality units.

In addition, the draft outlines the need for written quality agreements with suppliers to ensure CGMP compliance and clear communication of responsibilities.
