In the modern pharmaceutical industry, it is critical to ensure the safety, quality, and efficacy of healthcare products. An important process for preserving the stability of such products is lyophilization, also known as freeze-drying. Lyophilization is a widely used method in the pharmaceutical industry to preserve products, especially biological materials, by removing water through sublimation and desorption under controlled conditions. Indian Standard IS 18881 (Part 3): 2024, focuses on aseptic processing of health care products, especially lyophilization. This standard plays an important role in ensuring that the lyophilization process is carried out with the highest standards of sterility and safety.
