Abstrakt:	This study investigates the transformation of neat starch (NS) from mung beans into porous starch (PS) for the formulation of fast-disintegrating tablets (FDTs) using the sublimation technique, contrasting their performance with superdisintegrants such as sodium starch glycolate (SSG) and croscarmellose sodium (CS). Camphor was used as a sublimating agent. The interaction between drug and excipients was analyzed using Fourier-transform infrared spectroscopy (FTIR), while preformulation assessments were conducted on powder blends. Model drug Diclofenac sodium (DL)-loaded FDTs were prepared via direct compression technique. Thermal behavior and crystalline properties were evaluated using differential scanning calorimetry (DSC) and powder X-ray diffraction (PXRD), respectively. Compressibility of tablets was assessed through Heckel and Kawakita analyses. Post-compression evaluations encompassed hardness, thickness, in vitro disintegration, and dissolution studies. FTIR analysis indicated the absence of chemical interactions among constituents, while precompression analyses confirmed favorable flow properties of the blends. Heckel analysis supported the material's notable compressibility. Microscopic examination revealed the formation of pores on the tablet surface due to the sublimation process. Integration of PS significantly accelerated the disintegration time of FDTs, with durations ranging from 50 to 82 s, compared to 76-104 s for NS-FDTs. While PS-FDTs exhibited a longer disintegration time compared to SSG, they demonstrated faster disintegration compared to croscarmellose sodium. A significant disparity ( p<0.01 ) in drug release at 60 min was observed between SSG and PS-FDTs, with DP3 achieving 97.65 % drug release. Most batches followed the Korsmeyer-Peppas model, except for DN2 and DN3, which adhered to Higuchi-matrix drug release kinetics. Stability assessments after 90 days revealed no significant differences ( p>0.05 ). Conclusively, this study highlights the effectiveness of PS and the sublimation method in creating FDTs with enhanced drug release properties.
