Abstract:

In the present study, we aimed todetermine the quality of different brands (Test1Test6) of mefenamic acid, which are commercially available in local market of Karachi, Pakistan. Various quality evaluation tests, including weight variation, hardness, thickness, friability, disintegration, assay and drug release, were carried out. Results were found to be in acceptable limits. Moreover, release profiles were compared using different dissolution media, such as phosphate buffer pH 6.8, 7.4 and biorelevant media (FaSSGF, FaSSIF, FeSSIF and SCoF). Release profiles at pH 6.8 and 7.4 were evaluated by one-way ANOVA, model-independent and model-dependent methods. Results of ANOVA showed that no significant difference was found among tester and reference brands (Test1Test6). Similarly, all the brands were found to be best fitted with Weibull model.

Key words: Mefenamic acid, One-way ANOVA, Model-independent, Model-dependent method, Biorelevant media
