Formulation and evaluation of extended-release tablets of trimetazidine HCL

The present study was undertaken with an aim to formulate develop and evaluate Trimetazidine HCL extended release matrix tablets using different polymers as release retarding agent. Pre formulation study was done initially and results directed for the further course of formulation. Based on Pre formulation studies different batches of Trimetazidine HCL were prepared using selected excipients. Powders were evaluated for tests Angle of repose, Bulk density, tapped density, compressibility index, and Hausner ratio before being punched as tablets. It was concluded that the tablets of batch F9 had considerable swelling behaviors and in vitro drug release. Percentage drug release in 8 hr is 80.77.  It was observed that tablets of batch F9 followed the Huguchi release profiles. From the results and discussion it is concluded that formulation of Extended release matrix tablet of HCL containing HPMC K-15 (19.44%) and Hyper mellose (19.44%), Ethyl cellulose (19.44%) batch F9 can be taken as an ideal or optimized formulation Extended release matrix tablet for 8 hour release as it fulfills the requirements for extended release matrix tablet.
