The aim of present work was to design and evaluate sustained release matrix tablets of antihyperlipidemic drug. In the present investigation, polymers used in different combinations such as Eudragit RL100 and HPMC E5 in the ratio of 1:1, 1:2, 1:3 and vice versa with PVP K25 using direct compression technique were prepared. The tablets were evaluated for physical parameters like thickness, hardness, friability, weight variation, and in vitro release studies. The FTIR study indicated that the drug is stable in formulation. The maximum drug release was found to be 94.41% over a period for 12 hours for F4 batch, thus concluded that as the concentration of Eudragit RL100 is increased the drug release decreased. The drug release mechanism followed non-fickian transport from both polymer matrices. All the formulations were stored at 25 0 C/60% RH and 45 0 C/75% RH for 3 months. It showed that all the formulations were physically and chemically stable.
