Case Studies on Problem Cycles and or Formulations of Lyophilized Products
This interactive webinar will cover several case studies in failed freeze-dried products due to poorly designed cycles, and or poorly designed formulations.
Attendees will be presented with all of the data from the failed batch, and will be given time to respond as to why the batch failed, and what should be changed to prevent future failures.
This webinar will initially give a background on the basics of freeze-dried products and the freeze-drying process. Special attention will be given to the thermal properties of a product (glass transitions, eutectic melts, etc.), and how these properties are affected by heat, residual moisture, and different excipients. Several case studies in failed freeze-dried products due to poorly designed cycles, and or poorly designed formulations will be presented in an interactive format., in which attendees will be presented with all of the data from the failed batch, and will be given time to respond as to why the batch failed, and what should be changed to prevent future failures.
Why Should you Attend:
Failed batches of lyophilized products are unfortunately an all too common event on those companies producing freeze-dried products, including pharmaceuticals, diagnostics, foods, vaccines, etc. Since freeze-drying is the most expensive unit operation of a manufacturing process, it is in a company’s best interest to keep failures to a minimum, and if they do occur, being able to quickly diagnose the failure and prevent it from happening again. By having a good understanding of the factors that can result in failed batches, and taking a methodical approach to determine why the failure occurred, the development scientist is in a much better position to quickly correct failures and prevent them from happening in the future, saving the company both time and money.
Objectives of the Presentation:
To guide in the understanding and performance of:
Critical temperatures in freeze-drying (Tg’, Te, Tc)
Thermal characterization including DSC and FDM
Understanding the effects of working with crystalline vs. amorphous components
The problem with working with a metastable glassy system and the use of annealing to correct this problem
Correctly diagnose failed batches and suggest changes to the cycle and or formulation to prevent the failure from reoccurring.
Who can Benefit:
This webinar will provide valuable assistance to those companies involved in the handling and manufacture of lyophilized products including:
