Recent years have seen notable progress in the use of deep eutectic solvents(DESs)in pharmaceutical applications.This is ascribed to the high preparation flexibility of DES mixtures and the ability tomulti-tune their physicochemical properties and biopharmaceutical characteristics.The aim of this article is to provide perspective concerning the applications of DESs in pharmaceutical systems and their potential based on the current state of the field.Notably,there is some disagreement about whether some mixtures are in fact DESs or ionic liquids(ILs)[1].This indicates the need for more robust standards and definitions so as to avoid confusion within the scientific community.Many studies consider DESs to either constitute a subclass of ILs,analogs of ILs,or alternatives to ILs.In this regard,it would be best for the IUPAC to standardize DES classification and their similarity/dissimilarity with ILs.
