Lyophilization Validation: A Regulatory Perspective

• Studies where shelf temperature and chamber pressure were offset from commercial set-points – High and low shelf temperature – High and low chamber pressure • Sometimes time is also varied during these studies • Not required for fixed cycles but provides confidence in lyophilization process 18

The Significance of Humidity Control in GMP Compliant

Aug 15 2018Figure 1: Effect of RH% on materials in static locations It is important to note the relationship between relative humidity (RH%) and air temperature as variations in temperature also will affect the RH% For example a sufficiently large drop in air temperature can result in water vapor condensing out Alternatively cold surfaces will cause condensation
