Background

The regulation of medical gases under the Current Good Manufacturing Practice (CGMP) framework has a long history, reflecting the evolving understanding of safety and quality in the pharmaceutical industry¹. Initially, medical gases were regulated under broader CGMP regulations applicable to all pharmaceuticals¹. However, the unique properties and critical applications of medical gases highlighted the need for specific, tailored regulations³.

Historical Context:

• Early Regulations: Medical gases have been a crucial part of healthcare for decades, with oxygen being one of the earliest and most widely used medical gases. The initial regulatory framework treated medical gases similarly to other pharmaceuticals, without specific provisions to address their unique characteristics^{4, 5}.
• Emergence of Specific Standards: Over time, it became evident that the general CGMP regulations were insufficient to address the complexities associated with the production, storage, and distribution of medical gases. This led to the development of dedicated regulations aimed at ensuring the safety, efficacy, and quality of these critical products^{6, 7}.

Previous Versions:

• The CGMP regulations for medical gases have undergone several iterations. Earlier versions focused on basic quality control measures and manufacturing practices. However, advancements in technology, increased understanding of risks, and the growing diversity of medical gases necessitated more comprehensive and detailed regulations^{8, 9}.
• Periodic Revisions: Over the years, the regulations have been periodically revised to incorporate new scientific knowledge, address industry feedback, and respond to emerging challenges. Each revision aimed to enhance the clarity, applicability, and effectiveness of the regulations ^{1, 3}.

Need for Updates:

• Technological Advancements: With rapid technological advancements in the production and distribution of medical gases, the regulations needed to be updated to reflect current industry practices and technological capabilities¹².
