SDs are prepared to improve the dissolution properties and bioavailability of slightly water-soluble drug molecules by dispersing them into an inert hydrophilic carrier. Aims and Objective: Evaluate the dissolution and solubility of Solid Dispersion of Lercanidipine Hydrochloride (LER). Materials and Methods: To study the effect of polymer, dissolution and solubility studies were carried out. Solid state characterizations of prepared solid dispersions were performed by differential scanning calorimetry (DSC).Drug- carrier interactions were studied by FT-IR spectroscopy, whereas X-ray diffraction of powder was done to demonstrate the crystal structure of the dispersions. Results: The prepared solid dispersion exhibited 94% drug release at 30 minutes which is higher than both LER pure and LER MKT. Better dissolution characteristic of solid dispersion was confirmed by 9.86 min M...
