Abstract
The present work mainly focuses on solubility enhancement of poorly soluble drugs using superdisintegrants. One of such poorly soluble drugs is Atorvastatin, which belongs to the category of statins. Atorvastatin belongs to BCS class – II, which is poorly water soluble and highly permeable. Natural sources are now-a-days playing a key role in pharmaceutical research. They have several pharmaceutical applications. Starches obtained from plants are pharmaceutically useful as binders, diluents, disintegrants and lubricants. Various physical parameters were evaluated. Solid dispersions were prepared using solvent evaporation technique. Where as in solid dispersions, formulations F2 and F5 showed better dissolution rate compared with other formulations. Fourier Transform Infra red spectroscopy (FTIR) and Differential Scanning Calorimetry (DSC) studies for optimized formulations revealed that there were no major interactions between the drug and excipients. X-Ray Diffraction (XRD) studies revealed the crystalline and amorphous nature of formulations. Scanning Electron Microscopy (SEM) revealed the surface characteristics. Thus from the present study, it was concluded that Entada scandens seed starch posses superdisintegrant property.
