Demonstrating the stability of medicines ensures reliable efficacy. Jäger carries out stability tests, for example in accordance with ICH Q1A, and photostability tests in accordance with ICH Q1B, both in-house and at independent external labora­tories, to ensure the service life and shelf life of your product or packaging. This involves determining how a product changes under specific conditions (temperature, humidity, light) over a specific period of time. The results are used to determine, amongst other things, the shelf life and recommended storage conditions for a product.
