CONCLUSION:
In these days, the use of co-crystals is an emerging trend to improve the physico-chemical properties of the API’s. The knowledge of complementary functional groups to create a new co-crystal has been successfully implemented in this research
work. The Aceclofenac-Nicotinamide molecular
complexes were prepared by neat grinding (ACF- NI NG) and solution crystallization methods with DMSO as solvent (ACF-NI). These were characterized by FTIR, DSC, Mass studies and SEM. The results from FTIR, DSC, Mass studies and SEM confirm the formation of the new crystal phases. From the FT-IR results, possible hydrogen bond motifs were generated. From this research work it can be established that Aceclofenac and Nicotinamide can form a co-crystal by both neat grinding method and solution crystallization method by using DMSO as solvent. Also, it can be concluded that FT-IR, DSC and Mass were effective tools for co-crystal screening and also. The analysis of the crystal forms to study their pharmaceutically significant nature is necessary, which is the subject of further study.
