The effect of cosolvents and surfactants on the aqueous solubility of Irbesartan [PDF]

open access: yes, 2009
It was considered an interest to enhance the aqueous solubility of irbesartan. To accomplish this objective, the solubilization of irbesartan by cosolvency and micellization was investigated.

Preferential solvation in polymer cosolvent systems: Polystyrene + cyclohexane + ethanol and poly(vinyl‐2‐pyridine) + nitromethane + carbon tetrachloride

open access: yes, 1988
Two cosolvent systems are studied by light scattering and viscosity measurements. The cosolvency mechanism is discussed in relation to the preferential adsorption, solubility parameter, and excess free energy of mixing of the two liquid components.
