Indomethacin (IMC) is an anti-inflammatory drug whose physiochemical properties in aqueous solutions have not been studied thoroughly. For this reason, in this work the validity of the Jouyban-Acree and Yalkowsky-Roseman models is evaluated to predict the solubility of this compound in ethanol + water cosolvent mixtures. The solubility estimation is studied as a function of temperature and cosolvent composition. Both models require only the experimental solubility values in the pure solvents at all the temperatures evaluated. The solubility calculated values by using both models deviate notoriously from experimental values in several cases.

Palabras clave : indomethacin; ethanol + water cosolvent mixtures; Jouyban-Acree; Yalkowsky- Roseman models.
