Due to the allocation of synchrotron beamtime, we had the opportunity to explore the effect of storage time on the same tablets to observe whether the conversion back to Form I would occur. Stability testing of pharmaceutical products is a critical component of the drug development process. As part of this study, we have been able to follow drug-excipient compatibility as a function of time by collecting data one month after the initial compaction. Where possible, we used the same tablets that were used initially but, in some cases, this was not possible due to the tablet fracturing while unmounting the sample from the goniometer. The tablets were stored under the same low temperature and high relative humidity conditions. Overall, visually, the samples showed a significant increase in the roughness of the overall tablet surface upon 1 month of storage.
