Melting Diagrams of Adefovir Dipivoxil and Dicarboxylic Acids: An Approach to Assess Cocrystal Compositions

Crystals, 2019
Pharmaceutical cocrystallization is a useful method to regulate the physical properties of active pharmaceutical ingredients (APIs). Since the cocrystals may form in various API/coformer ratios, identification of the cocrystal composition is the critical

Cocrystals of Praziquantel with Phenolic Acids: Discovery, Characterization, and Evaluation

Molecules, 2022
Solvent-assisted grinding (SAG) and solution slow evaporation (SSE) methods are generally used for the preparation of cocrystals. However, even by using the same solvent, active pharmaceutical ingredient (API), and cocrystal coformer (CCF), the ...

A Review on Pharmaceutical Cocrystals

International Journal of Pharmaceutical Research and Applications
Pharmaceutical cocrystals are crystalline materials composed of two or more different molecules, at least one being an active pharmaceutical ingredient (API), in a fixed stoichiometric ratio, held together by non-covalent interactions.Cocrystal can be prepared by cocrystallization method.
