ABSTRACT
A simple, precise, accurate, economical and reliable UV spectrophotometric method has been developed for the estimation of Olopatadine hydrochloride in bulk and its tablet dosage form. The drug shows maximum absorption (λmax) at 231 nm in methanol and obeys Beer’s law in the concentration range of 3-15 μg/ml with correlation coefficient (R2=0.999). The accuracy was found to be 97.2-99.6%. Limit of detection (LOD) and limit of quantification (LOQ) were found to be 0.047 μg/ml and 0.144 μg/ml respectively. The relative standard deviation was found to be
