FORMULATION AND EVALUATION OF MEFENAMIC ACID SUSTAINED RELEASE MATRIX TABLETS
*Shaik Saddam Hussain and U. Sambamoorthy
Abstract
The objective of the present study was to develop once daily sustained
release matrix tablets of Mefenamic Acid 200mg by using direct
compression method using different polymers like HPMC K4M,
HPMC K15M, HPMC K100M. The drug excipient mixtures were
subjected pre formulation studies. The Tablet were subjected to
physicochemical studies, In- Vitro drug release, kinetics studies. FTIR
studies shown there was no interaction between drug and polymer. The
drug release from optimized formulations was sustained for a period of
12hrs. The kinetic treatment of selected formulation F7 showed that
the release of drug follows zero order models. Results of the present
study indicated the suitability of hydrophilic polymers in the
preparation of matrix based sustained release formulation of
Mefenamic Acid.
