The elimimation of mefenamic acid has been carried out by photolysis, ozonation, adsorption onto activated carbon (AC) and combinations of the previous single systems (O3+AC and O3+UV). The results obtained indicate that mefenamic acid is not photo-reactive, showing a relatively low quantum yield of the order of 6 x 10 mol Einstein. Application of ozone to mefenamic aqueous solutions instantane...

The main aim of the present research was to encapsulate mefenamic acid in niosomes andincorporate the prepared niosomes in the carbopol gel base for sustained therapeutic action. Mefenamic acid loaded niosomes were prepared by thin film hydration technique and evaluated for entrapment efficiency, vesicular size and zeta potential. The entrapment efficiency of the prepared niosomes was found to ...

The effect of non-steroidal anti-inflammatory drugs (NSAIDs) on ion channels has been widely studied in several cell models, but less is known about their modulatory mechanisms. In this report, the effect of mefenamic acid on voltage-activated transient outward K(+) current (I(A)) in cultured rat cerebellar granule cells was investigated. At a concentration of 5 microM to 100 microM, mefenamic ...

A spectrophotometric method of assay of mefenamic acid in tablets involving, dissolving the tablet powder in 1,4-dioxane and measuring the absorbance at 353.2 nm. The concentration of mefenamic acid is determined using the previously prepared calibration curve using standard solution of mefenamic acid in dioxane. The method was tested by assay of six different commercial tablets containing mefe...

A 52 year old man developed bullous pemphigoid, Coombs' positive haemolytic anaemia and diarrhoea related to the use of mefenamic acid. Clinical manifestation of the bullous pemphigoid, haemolytic anaemia and diarrhoea resolved following discontinuation of the mefenamic acid. Mefenamic acid should be added to the list of agents that are known to induce bullous pemphigoid.

the present work describes a reverse phase hplc method for the quantitation of drotaverine hydrochloride and mefenamic acid in human plasma. organic solvent system used for liquid extraction composed of dichloromethane, and isopropyl alcohol in the ratio 80:20 (v/v). the compounds were separated on a thermo bds hypersil c8 (25.0 cm×4.6 mm, 5 µm particle size) column in isocratic mode with a mix...
