Cocrystals – All About Drugs
An early development compound initially used neat grinding with a mixer ball mill. Twenty-five conformers were used for this stage of the study, and equimolar ratios of the drug ( 60 mg) and coformer were ground for 20 min. Solids were analyzed, and those that showed a different DSC trace and XRPD pattern were classified as leads.
