Description: This article discusses the solubility of budesonide, hydrocortisone, and prednisolone in ethanol and water mixtures at 298.2 K. Abstract: Experimental solubilities of budesonide, hydrocortisone, and prednisolone in ethanol + water mixtures at 298.2 K are reported. The solubility of drugs was increased with the addition of ethanol and reached the maximum values of the volume fractions of 90%, 80%, and 80% of ethanol. The Jouyban−Acree model was used to fit the experimental data, and the solubilities were reproduced using previously trained versions of the Jouyban−Acree model and the solubility data in monosolvents in which the overall mean relative deviations (OMRDs) of the models were 5.1%, 6.4%, 37.7%, and 35.9%, respectively, for the fitted model, the trained version for ethanol + water mixtures, and generally trained versions for various organic solvents + water mixtures. Solubilities were also predicted by a previously established log−linear model of Yalkowsky with the OMRD of 53.8%.
