Abstract
The present invention fabricates mesocrystals of organic and organo-metallic compounds. Supersaturated solutions are made with different sums of an organic or organo-metallic compound and the organic or organo-metallic compound is added with an excipient. Through a water bath, mesocrystals are obtained from the supersaturated solutions with well-faceted nucleation and growth. Different polymorphisms are induced with different ratios of enantiomers. And the dissolution rate for fabricating the API is enhanced.
