The aim of the present study is to enhance solubility of simvastatin by solid dispersion technique. Solid dispersions were prepared by fusion method by using various polymers. Formulation is optimized on the basis of acceptable solid dispersion properties and in-vitro release. In order to obtained best optimized product, 5 different formulations were developed. Different polymers like PEG 6000, HPMC 6000,HPC 1000 were taken as variables. Angle of repose, carr’s index, particle size, drug content and dissolution study were studied as response variables. The different physical properties showed best comparable results with drug. But higher percentage of drug release was observed when the formulation contained PEG6000 in 1:1.5 ratio (f5) compared to other formulations. Form this study it concluded that formulation (f5) which contained PEG (1:1.5) as polymer showed best dissolution profile compared to the drug. The formulation contained PEG 6000 was selected as optimized product.
