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 (p ˂ 0.05). 0.2% (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.</p></abstract>

En iyi formülasyonu elde edebilmek adına Design Expert programı ile 34 faktöriyel tasarım uygulanmıştır. PVA konsantrasyonu, PVA molekül ağırlığı, solvan/antisolvan oranı ve etanol/PEG 300 oranı formülasyon parametresi olarak kullanılmıştır ve bu parametrelerin değişikliğinin partikül büyüklüğü ve dağılımı üzerine olan etkisi incelenmiştir.Sonuç ve Tartışma: Nanosüspansiyonlar solvan/antisolvan yöntemi ile başarılı bir şekilde hazırlanmıştır. Nanosüspansiyonların partikül boyutu ve polidispersite indeksinin hem molekül ağırlığından hem de antisolvan fazdaki PVA yüzdesinden etkilendiği bulunmuştur (p ˂ 0.05). %0.2 PVA; PVA için 3000 molekül ağırlığı ve 3:50 çözücü-antisolvan oranı, nanosüspansiyon formülasyonları için optimal parametreler olarak bulunmuştur.
