A method for quantitative measurement of the photochemical decomposition of the anti-inflammatory agent, indoprofen (INP) is descriped. An RPLC-based assay that could determine the extent of degradation of INP in a rapid, sensitive, and accurate manner was developed. The method was validated under photoirradiation. Quantitation was monitored with an Inertsil ODS-3V column using a mobile phase of acetonitril and 1% HOAc solution in deionized H 2O. Statistics relevant to the system criteria, peak integrity and resolution among the parent drug and its degradation products were performed. From the intra- and inter-day tests, the coefficients of variation were found to range from 0.59% to 4.25% for the former and from 0.71% to 4.86% for the latter. The good selectivity and specificity of this RPLC-based procedure render it suitable for measurements of INP stability.
