Recommended Best Practices for Lyophilization Validation
R p increases with time during primary drying with the maximum value of R p observed towards the end of primary drying (Figure 4). There is a sharp increase in R p directly after 17 h of primary drying time. This occurs after all ice sublimes and resistance becomes a function of diffusion of unfrozen water through the drying solid.
