ARTICLE INFO ABSTRACT Article history Received 02/12/2018 Available online 31/12/2018 Keywords Eletriptan Hydrobromide, Marquis Reagent, Visible Spectrophotometric Method. A novel, simple, sensitive, precise and accurate visible spectrophotometric method has been developed and validated for the determination of Eletriptan hydrobromide in pharmaceutical formulation using marquis reagent. The absorption maximum of the drug was found to be 530 nm. The linearity was obtained in the concentration range of 2-12 μg/ml with correlation coefficient 0.998. The results of analysis for the method have been validated statistically and by recovery studies indicate the accuracy and precision of the method. The proposed method was simple, accurate, and precise hence can be applied for the analysis of Eletriptan in pharmaceutical tablet dosage form.
