Abstract

Coâ€crystal chemistry has recently attracted supramolecular scientists. Coâ€crystals are comprising of hydrogen boding
assembly between different molecules. Many issues related to performance characteristics of an active pharmaceutical ingredient (API) can be resolved using coâ€crystallization approach. Proper understanding of crystal structure of an API is required for successful formation of coâ€crystals with the selected coâ€former. This review article focus on explanation about coâ€crystals, intellectual property rights, their advantages and limitations. Coâ€crystallization can be achieved using different methods like coâ€grinding slurry based, solvent evaporation method, etc. Methods of coâ€crystallization are simple and increase the purity of the final product. Coâ€crystallization can be applied to the drugs prescribed in combination therapy. Stoichiometric composition of different drugs used in combination therapy can be coâ€crystallize to form one solid state form. Physicochemical properties of APIs such as solubility and stability can be improved using coâ€crystallization approach. With due regards coâ€crystallization should be used with caution because of some issues during manufacturing of final product.

Key words: Chiral switch, crystal engineering, hydrogen bonding, intellectual property rights, polymorphism
