Effect of various stabilizers on the stability of lansoprazole nanosuspension prepared using high shear homogenization: Preliminary investigation
Abstract
The purpose of the current research work was to prepare a nanosuspension of the model drug lansoprazole (LSP) and investigate the effect of various stabilizers on the stability of the nanosuspension prepared using the high shear homogenization technique. In this study, polymeric stabilizers like polyvinylpyrrolidone K-30, polyvinylpyrrolidone K-90, polyvinyl alcohol, sodium alginate, and hydroxypropyl methylcellulose E15 and surfactants like sodium lauryl sulfate and Tween 80 were explored. The prepared nanosuspensions were evaluated for particle size distribution (PSD), polydispersity index (PI), zeta potential, and drug loading. Saturation solubility and in-vitro dissolution studies of optimized nanosuspension and coarse LSP powder were also carried out to determine the extent of solubility…
