    摘要: An approach to designing families of cocrystals with desired (tunable) pH dependent dissolution is developed. The solubility and dissolution rate of a family of cocrystals with the same API and a series of ligands that are weak acids or weak bases has been found to be determined and controlled by the acid or base dissociation constant of the ligand and the pH of the dissolution medium. In various aspects, pH dependent dissolution is imparted to a non-ionizable API or the dissolution of ionizable API's is modulated.

    摘要: Multi-component crystals (co-crystals) are prepared by combining co-crystal components in non-stoichiometric concentrations in solution. The solubility of the molecular complex in the solvent is reduced, increasing the probability that the molecular complex is the least soluble form in the system, upon which it precipitates. A crystalline product is produced without the need for grinding, solvent evaporation, or temperature variation.
