The main of the research work to develop sustained release floating matrix tablets of ATZ, which were designed to extend the gastric residence time and prolong the drug release after oral administration. Different grades of polymers such as EC and HPMC K100M were used in order to get the desired floating and sustained release profile over prolonged period of time. All the formulations extended the drug release up to 24 hours and more and the formulations were optimized for the desired release profiles. The release and floating property was depends on the polymer type and polymer proportion. The formulation prepared with Ethyl cellulose and HPMC K100M has more floating time than the formulation prepared with the Ethyl cellulose alone. The FTIR study shows that there is no drug-polymer interaction. This study gives the preliminary idea about the development of the floating drug delivery systems of Atazanavir without the use of gas generating agent.
Atazanavir sulphate, Ethyl cellulose (N20), Ethyl cellulose(N22), Ethylcellulose (N45), Ethyl cellulose(N50), Ethyl cellulose(N100), HPMC K100M, Magnesium Stearate
