Abstract
Photodegradation of meloxicam is studied placing special emphasis on the investigation of the correlation between the sample concentration and the stability. For quantitation a HPTLC assay was developed. The stability indicating capability ofthe assay is proved using a sampie solution exposed to artificial irradiation from a xenon source, the peak of meloxicam was weil separated from all
degradation products. For quantitation external calibration is employed. Sample solutions of meloxicam of three different concentrations (2 mg ml-1; 250 μg ml-1 ; 40 μg ml-1) are subjected to simulated sunlight and tested for stability.
