- solubility of poorly soluble inabogliflozin was improved by using a surfactant, it is assumed that there is a possibility that the interaction between the main ingredient and the surfactant may be affected during stability and storage. Therefore, it can be evaluated indirectly by measuring the cloud point, where the solubility rapidly decreases when the water-soluble group of the nonionic surfactant is dehydrated upon heating. Accordingly, the cause of the instability of the formulation was identified, and the solubilizer was changed to further stabilize the formulation, and formulation research was conducted.
