Background & Aim: Solid dispersion has attracted considerable interest as an efficient means of improving the solubility and the dissolution rate of poorly water-soluble drug. The aim of this study was to prepare solid dispersions of famotidine with HPMC E5LV and mannitol as carrier to improve its solubility and its dissolution rate. Methods: Co-grinding techniques by using ball milling was used. 18 formulae with 3 different ratios to HPMC and mannitol (1:1, 1:2, 2:1) and 3 different grinding times (30��?, 60��?, 90��?) were prepared. Characterization of solid dispersion was analyzed with scanning electron microcopy analysis (SEM), X-ray diffraction, Fourier transform infrared (FTIR), optilab microscope camera, solubility test and dissolution test. The solid state interaction of co-ground and physical mixture was evaluated by X-ray powder diffraction and SEM. The dissolution studies were conducted in USP type II apparatus. Results: The result of X-ray powder diffraction analysis showed that the co-ground of famotidine with HPMC E5LV and mannitol decreased the drug crystallinity. X-ray powder diffraction showed the transformation of crystalline state of famotidine to amorphous by co-grinding with HPMC E5LV and mannitol. Conclusion: SEM results showed the co-ground mixture with HPMC E5LV had smaller size and co-ground mixture with mannitol showed agglomerate form. The highest in solubility and dissolution rate was observed for famotidine-HPMC and E5LV showed in 1:1 ratio with 90��? grinding time and famotidine-mannitol showed in 1:2 ratio with 30��? grinding time compared to the intact famotidine and its physical mixture.
