Abstract :Objective: In this study, it was aimed to prepare nanosuspensions that contains Indomethacin which is a BCS class II drug. To assess the cumulative impact of the chosen variables on the nanosuspension properties, a 34 factorial design was applied and particle size and distributions were examined. Material and Method: In the study, the solvent/antisolvent method was used in the preparation of the suspensions. 34 factorial design. Design-Expert software was used for the evaluation of the prepared formulations in order to obtain the best formulation. PVA concentration, PVA molecular weight, solvent/antisolvent ratio, and ethanol/PEG 300 ratio were used as independent design parameters, and their effects on particle size and distribution were examined. Result and Discussion: Nanosuspensions were successfully prepared by the solvent/antisolvent method. Particle size and polydispersity index of the nanosuspensions were found to be affected by both molecular weight and percentage of PVA in the antisolvent phase insert ignore into journalissuearticles values(p ˂ 0.05);. 0.2% insert ignore into journalissuearticles values(w/v); PVA; molecular weight of 31 000 for PVA and the solvent-antisolvent ratio as 3:50 were found to be the optimal parameters for the nanosuspension formulations. The particle size and polydispersity of optimum formulation were found 301.5 ± 31.1 nm and 0.159 ± 0.035, respectively.
