The thermodynamic parameters for the solubilization process are presented. ; Myerson, A.S. A priori design and selection of ionic liquids as solvents for active pharmaceutical ingredients. Because of their superior characteristics and eco-friendliness, ILs are a viable alternative to traditional solvents. This high solubility level allows paracetamol to dissolve readily in room temperature water along with the desired codeine in the pills. Net organic solvents solubilize Ibu better than water. Refrigeration and filtration can be repeated if a clearer solution is desired, but this is usually unnecessary and wasteful, as each successive filtration will reduce the opioid content as it is absorbed by the filter material.
