When in Phase I, II, III..,
Assume photostability testing was completed on naked, foiled, packaged material – and naked samples showed some sensitivity at the end of exposure –
Would you label the samples as “Protect from light”? Also if you havent conducted photostability testing – would you label the samples “Protect from light” as a premptive measure?
If photostability testing is not the only measure to consider “protect from light” labelling – what other studies do you conduct?
