The degradation behavior of Ropinirole Hydrochloride (ROPI) was investigated under various stress conditions of acid/base hydrolysis and oxidation using Spectrophotometry. Stability indicating spectrophotometric method was developed that could separate the drug from its degradation products formed under these stressed conditions. The UV spectral characteristics of the drug and degraded products were quite different and first order derivative UV spectrophotometric method was used to study the extent of degradation. ROPI was found to degrade extensively under experimental conditions. The method was validated with respect to linearity, precision, accuracy and specificity. The described method was found to be linear over the range of 5-50 µg mL-1 for ROPI. The mean recovery was found to be 99.03±1.11, %. The intermediate precision data were obtained under different experimental conditions and calculated value of the coefficient of variation (CV, %) was found to be less than critical value. The proposed method can be successfully useful to determine the degradation of drug during storage.
