Microbiological quality standard for pharmaceutical compressed air

2026-04-14Views:

The microbiological quality standards for pharmaceutical compressed air are mainly formulated according to the Good Manufacturing Practices (GMP) and relevant international standards. The following is a detailed summary of the microbiological quality standards for pharmaceutical compressed air:

1. microbiological limit standard

  • international Standards: According to the ISO 8573 series of standards, for compressed air for pharmaceutical use, the microbial limit is usually less than 1 CFU/m & sup3;(colony forming unit per cubic meter). This standard is widely used in the global pharmaceutical industry to ensure the sterility of compressed air.
  • China GMP Standard: In China, according to the requirements of the "Pharmaceutical Production Quality Management Regulations", the production gas (including compressed air) entering the sterile production area should be sterilized and filtered. For compressed air filtered by terminal sterilization, the number of microorganisms shall be less than 1 CFU/m & sup3;. This standard is consistent with international standards and reflects the high requirements of the Chinese pharmaceutical industry for microbiological control.

Detection and monitoring of 2. microorganisms

  • detection method: The detection of microorganisms in compressed air for pharmaceutical use usually adopts the culture method, that is, a certain amount of compressed air sample is cultured through the culture medium, and then the number of colony forming units is calculated. In addition, a method such as a buoyant bacteria sampler can also be used for detection.
  • Monitoring frequency: According to GMP guidelines, for compressed air for pharmaceutical use, the inspection period should be determined according to the system verification results and product risks. In general, the inspection cycle for newly installed systems can be set at 3 months and for mature systems at 6 months to 1 year. In actual operation, pharmaceutical companies should formulate reasonable monitoring plans according to their own conditions to ensure that the microbial quality of compressed air meets the standards.

Control Measures of 3. Microorganisms

  • sterilization filtration: In pharmaceutical compressed air systems, sterilization filters are usually installed to remove microorganisms in the air. The sterilization filter should have high-efficiency filtration performance and be replaced regularly to ensure its filtration effect.
  • system design and operation the design of the pharmaceutical compressed air system should consider the factors to prevent microbial contamination, such as the use of stainless steel materials, avoiding dead corners and stagnant water. During operation, the system should be cleaned and disinfected regularly to prevent the growth of microorganisms.
  • Environmental Control the pharmaceutical workshop should maintain a clean and dry environment to reduce microbial contamination in the air. In addition, the movement of personnel and the entry and exit of goods should be controlled to prevent external microorganisms from being brought into the workshop.

4. other relevant standards

  • in addition to the microbiological limit standards, pharmaceutical compressed air should also meet other relevant standards, such as water content, oil content, dust particle number, etc. Together, these standards form a system of quality requirements for pharmaceutical compressed air.

In summary, the microbiological quality standard of pharmaceutical compressed air is an important part of quality control in the pharmaceutical industry. Pharmaceutical companies should strictly follow relevant standards to ensure the sterility of compressed air, thereby ensuring the quality and safety of drug production.
