Methods: Co-crystal was prepared by using melt crystallization method of MFA-NCT (1:2) at (220±3°C). The initial co-crystal formation was performed by powder X-ray diffraction (PXRD). The thin-layer chromatography (TLC) method was done to confirm the chemical stability of MFA and NCT due to synthesized process. The melt crystallization of MFA-NCT (1:2) was characterized by differential scanning calorimetry (DSC)/thermal gravimetric, infrared spectrophotometry, and scanning electron microscopy. The solubility of the melt crystallization of MFA-NCT (1:2) was evaluated by incubating the samples in water at 25°C and shaken for 24 hrs. The solubility of MFA was measured by ultraviolet-visible spectrophotometer. Result: Characterization of a co-crystal MFA-NCT (1:2) including PXRD, Fourier transform infrared, DSC, and SEM have indicated the formation of new solid crystal phase that differs from MFA, NCT, and its physical mixture. The chromatogram of the TLC study exhibited two spot that corresponds to MFA and NCT. The solubility of the melt crystallization of MFA-NCT (1:2) was 57.97% higher than MFA solubility. Conclusion: These results suggest that MFA-NCT co-crystal can be synthesized by using melt crystallization method without decomposition of its component and provides an opportunity for the development of MFA solid form.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Co-crystal,Mefenamic acid,Melt crystallization,Nicotinamide,Solubility[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.22159/ajpcr.2017.v10i5.15863[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
