*2.6. Stability Test*

The stabilities of ARI-SAL salt and ARI-ADI salt acetone hemisolvate were studied under high-temperature (60 ± 1 ◦C) and high-humidity (95 ± 5%) tests. Materials were randomly selected and exposed to high temperature and high humidity conditions. The storage times were 10 days and PXRD was applied to measure the final samples.
