    • Poor solubility of the parent API (free acid or free base) is a long-standing problem. More than 40% of newly discovered drugs have little or no water solubility (less than 0.1 mg/ mL).

    • In this case, the solvation energy for both salts in the pair should be the same or very similar. Therefore, solubility differences can be directly correlated with differences in crystal packing.
