Preferential Solvation of Drugs in Binary Solvent Mixtures

Marcus Y

The preferential solvation of many drugs in binary solvent mixtures, as derived by means of the quasi-lattice quasi-chemical and the inverse Kirkwood-Buff integrals methods from solubility and other thermodynamic data, is reviewed. The preferences were described in terms of the local mole fractions of the solvent components in the solvation sphere of the drug molecule and their differences with respect to these mole fractions in the bulk: the preferential solvation parameters. When data were available at several temperatures these preferences were described in terms of the enthalpic and entropic contributions.
