The aim of the present work was to design controlled release tablet of Tramadol hydrochloride for prolong release and it’s in vitro evaluation. Controlled tablets of Tramadol hydrochloride comprised HPMC K15M, and HPMC K100M as the release retarding polymers. These tablets were prepared by direct compression method. The seven different formulations (F1-F7) were evaluated for pre- and post-compression parameters. In vitro dissolution studies were carried out for the optimized formulation (F7). It has found that the release of drug from the sustained release layer by 99.5% in 12 h. FT-IR studies revealed that there was no interaction between the drug and polymers used in the study. The release of Tramadol hydrochloride was found to follow a pattern of Korsmeyer-Peppas, with Quasi-Fickian diffusion. Accelerated stability studies were carried out on the prepared tablets in accordance with ICH guidelines. There were no changes observed in physicochemical properties and drug release pattern of tablets. The controlled drug release pattern was successfully achieved through the formulation of controlled tablets in this study.

Keywords: Tramadol hydrochloride, HPMC K15M, HPMC K100M, Micro crystalline cellulose, direct compression, and In-vitro dissolution studies etc.
