Full Stability studies

One fundamental feature in a drug is to keep unaltered parameters as far as regards quality and effectiveness until the expiry date.

Stability studies, carried out according to legislation and guidelines accepted by the scientific community (in particular those coming from ICH, International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use), assess the way the features of a pharmaceutical active ingredient change in the course of time depending on different temperature and humidity conditions.
