    Extended release formulations are designed to release their medication in a controlled manner at a predetermined rate, duration and location to achieve and maintain optimum therapeutic blood levels of a drug. The present investigation is aimed to formulate the extended release matrix tablets of Tenatoprazole sodium with various grades of different polymers like Carbopol, HPMC and Eudragit grades. The tablets were prepared by wet granulation technique. The prepared ER Matrix tablets were evaluated for various physico chemical parameters. All the formulations resulted in acceptable Pharmacopoeia limits. In-vitro drug release studies (USP dissolution rate test apparatus II, 75 rpm, 37°C ±0.5°C) using 0.1N hydrochloric acid (1.2 PH ) for first 2 hrs and phosphate buffer (PH 6.8) as a dissolution medium (900ml) for the next 12 hrs. Among all the formulation F-5(drug: Carbopol-974P-NF in ratio of 1:1.5) shows better result upto 12 hours of the drug release was found to be 99.47±0.22 so it’s an Optimized formulation.

    Key words: Carbopol, ER Matrix, Eudragit, Methocel, Tenatoprazole sodium, Wet granulation.
