Determining the optimal secondary drying time in a lyophilization (freeze drying) cycle for drug products is critical for several reasons related to product quality, stability, and manufacturing efficiency:

Optimizing the secondary drying time during drug development is essential to balance quality, cost, and efficiency while ensuring compliance with regulatory standards and delivering a stable, effective drug product.
At ProJect Pharmaceutics CRO we are experts in lyophilization process development for injectable drug products. We have developed a smart approach to determine the required secondary drying time to achieve the target residual moisture content within a single (!) lyophilization cycle. By sampling sub-lots of vials closed at different time points during secondary drying, we can analyze up to ten (!) different, freely programmable timepoints during ongoing secondary drying.
If you would like to benefit from a secondary drying time that is optimally tailored to your product, please contact us.
