Meloxicam (MLX) is a potent non-steroidal anti-inflammatory drug with poor solubility. Solid dispersion (SD) is an effective formulation strategy to improve the dissolution rate of poorly water-soluble compounds. Hydroxy propyl methyl cellulose (HPMC) as an inert polymer carrier and nicotinic acid (NA) as disturbance can be used as a matrix of SD. The aim of this study was to determine the effect of MLX-HPMC-NA SD on the solubility and dissolution of MLX. SD was prepared by the solvent evaporation technique with methanol being used as a solvent. Methanol was evaporated at room temperature. SD of MLX was prepared involving various matrix compositions at MLX:HPMC:NA ratios of 1:1:1 (SD1), 1:1:2 (SD2), 1:2:1 (SD3), and 1:2:2 (SD4). The solubility profile of MLX in SD3 (64.34 ppm) showed a higher improvement than the physical mixture (15.99 ppm) and pure MLX (6.89 ppm). This increase might be due to the formation of molecular dispersion of MLX in the polymer as hydrophilic matrix and NA have both donor-acceptor sites for hydrogen bonding interactions. The dissolution profile of SD3 also showed the highest improvement. The melting endotherm of SD3 was detected at 219.5 °C, in which case it originated from NA rather than from MLX, showing that MLX was molecularly dispersed and amorphous. MLX solubility and dissolution profile could be improved by the SD technique with a matrix of HPMC and NA. The best result was given by SD3 with an MLX:HPMC:NA ratio of 1:2:1. Based on the characterization study, it is predicted that hydrophilic polymer and hydrogen bonding interactions play important roles in MLX solubility or dissolution rate improvement.
