Application of UV spectrophotometric method for easy and rapid estimation of lafutidine in bulk and pharmaceutical formulation

Introduction: The present research work discusses the development of a UV estimation method for lafutidine. Simple, accurate, cost efficient, and reproducible spectrophotometric method has been developed for the estimation of Lafutidine in bulk and pharmaceutical dosage form. Materials and Methods: The Stock solution was prepared in a mixture of water and methanol (1:1). Further dilutions were made in water. Results: The drug was determined at maximum wavelength (λmax) 279 nm. Beers law was obeyed in the concentration range of 10-50 μg/ml having line equation y = O.O1OOx + 0.035 with correlation coefficient of 0.999. Results of the analysis were validated statistically and by recovery study. Conclusion: The result of analysis was validated as per ICH guidelines and this method can be used for the routine analysis of lafutidine formulation.
