Stability conditions for WHO Member States by Region
The enclosed report is presenting the Stability Conditions required by a given Member State.
The main observation is that we can distinguish three main categories (with some exceptions).
+25°C/60% RH
+30°C/65% RH
+30°C/75% RH
A comprehensive approach would be to develop a stability program targeting the most relevant markets and focusing on +25°C/60% RH and +30°C/75% RH conditions. Justification as why +30°C/65% RH is omitted and that stability data generated at different conditions are predictable for behavior in other intermediate conditions.
