Some guidance would be helpful to the industry, but perhaps this should come in a separate guidance.

What could be made clear in the guideline is that both require- Figure 1. Quantitative photostability This would make the photostability testing in results must be evaluated together with long-term the containers more consistent with the direct stability results.
