Stability indicating RP-HPLC method of dexibuprofen in nanocream formulation: Identification and quantification..
Pak J Pharm Sci Jan ;33(4):1815-21.

A stability indicating reverse phase-HPLC method was designed for determination of dexibuprofen in drug solution and in nanocream formulation. Chromatographic conditions were optimized simply by adjusting the content and different compositions of reverse phase associated with mobile phases. Different parameters like specificity, limit of quantification (LOQ), limit of detection, linearity, range, system suitability, precision and accuracy were determined. Stability studies of dexibuprofen in nanocream were taken under the stressed situations of alkali, acid, oxidation process, UV and heat degradation. Tailing factor and % RSD were found >2000 and <2% respectively. The method was identified linear over the range of 0.2-1.6mg/ml having co-efficient of correlation 0.9995. Intra-day and inter- day precision and accuracy values for dexibuprofen were < 0.6% and <1.1032 and < 0.3% and 1.10% respectively. Stability studies showed that dexibuprofen was stable in nanocream against alkali, acid, oxidation, UV light and heat. The developed validated method was precise and accurate for the evaluation of dexibuprofen in solution as well as in nanocream formulation.
