Abstract

The main objective of the present work was to develop sustained release matrix tablets of Quetiapine fumarate by using different polymers viz., Hydroxy methyl propyl cellulose (HPMC) and Carbomer. Varying the ratios of drug and polymer like selected for the study. Quetiapine fumarate is prescribed for the treatment of Schizophrenia. It has a mean half life of 6hrs and administered at least thrice a day. The main objective of the study is to design once a day dosage form which can release the drug for 24hrs. The tablets were prepared by direct compression method. In-vitro dissolution studies showed that F7 has better release profiles when compared to other formulations. Though F4 showed release of 22hrs, the drug release was not constant. The experiment clearly stated that the usage of Carbomer has promoted the sustained release of QPF. Dissolution data was analyzed by Higuchi expression. Stability studies for 6 months indicated that Quetiapine fumarate was stable in the matrix tablets. The DSC and FTIR study revealed that there was no chemical interaction between drug and excipients.
