Register InterestNo Course Dates Currently Available


The purpose of this course is to give an overview of photostability and where it fits in the stability testing programme and the importance of photostability. The course is highly interactive and held in a relaxed environment.

It will cover:
  • Why do we do photostability tests?
  • Concepts and background in photostability
  • Identifying drug substances most likely to absorb light and display signs of poor photostability
  • Understanding photostability terminology
  • Where does photostability fit in the overall stability testing programme?
  • Why does photostability matter? (exercise)
