ABSTRACT
The aim of this study was to investigate the influence of superdisintegrants on the dissolution properties of a poorly water-soluble drug from complexes prepared by kneading method. Ketoprofen was employed as a model drug. Solid dispersions prepared by kneading method exhibited higher dissolution rate and DE30 values in each case. Ketoprofen tablets were prepared by direct compression technique using microcrystalline cellulose as a directly compressible vehicle. The formulated tablets were evaluated by different In Process Quality Control tests, content uniformity and in vitro drug release study. The FTIR spectra’s study revealed that there were no interaction between polymers and drug. All the tablets formulated employing solid dispersions in superdisintegrants gave rapid and higher dissolution of Ketoprofen when compared to that of Ketoprofen plain tablets. Ketoprofen dissolution from all the tablets followed first order kinetic with correlation coefficient ‘r’ above 0.9470. All dissolution parameters (k₁, DE₃₀ and T₃₀) indicated rapid and higher dissolution of Ketoprofen from tablets formulated employing its solid dispersions in superdisintegrants when compared to plain tablets.
