The importance of developing new pharmaceutical final formulations is nowadays well known. In this paper, we present the study of compatibility between bioactive antihyperlipidemic agent simvastatin and eight currently used pharmaceutical excipients for developing solid dosage forms, namely starch, microcrystalline cellulose, lactose monohydrate, polyvinylpyrrolidone, colloidal silica, talc, magnesium citrate and sorbitol. The compatibility investigations were carried out under ambient temperature by FTIR spectroscopy studies and PXRD patterns and then completed by the use of thermal analysis (TG/DTG/HF) data to study the influence of temperature over stability of binary mixtures.
