FORMULATION AND IN-VITRO EVALUATION OF SUSTAINED RELEASE MATRIX TABLETS FOR VALDECOXIB Authors: Babikir MAO And Akiladevi D*
ABSTRACT
Purpose: The ultimate aim of this current study was to design of sustained release matrix
tablets for valdecoxib.
Methodology: SR matrix tablets of were formulated by using wet granulation technique with
different polymers. The formulated SR matrix tablets are evaluated by characterization of
flow properties like angle of repose, bulk density, compressibility index, hausner’s ratio and
characterization of physiochemical properties such as thickness, diameter, weight variation
test, hardness, friability, drug content, in vitro drug release studies. Drug-polymers interaction
was predicted by FT/IR Spectroscopy and DSC method.
Results: The SR matrix tablets were formulated and evaluated for flow properties,
physiochemical characterization of matrix tablets, in vitro drug release studies. The in vitro
dissolution studies revealed that the release patterns of the VC8 containing HPMC K100M
and ethyl cellulose were probably showing maximum retardation of drug release and it shows
super case-II transport, for these reasons, it was considered that the formulation VC8 as best
formulation among all the nine formulations.
Conclusion: The results encourage a potential use of SR matrix tablet to prolong the
dissolution rate and hence its improvement in treatment efficacy and patient compliances
through oral route.
