A simple, precise, rapid and accurate Reverse Phase HPLC method was developed for the estimation of Lafutidine in tablet dosage form. An Inertsil ODS-3V, RP C18, 250x4.6 mm, column with 5 µm particle size and the mobile phase consisting of 0.02M Potassium Dihydrogen Orthophosphate + 0.02M Dipotassium Hydrogen Orthophosphate in water pH: 3.2 adjusted with Acetonitrile (30:70 v/v). Acetonitrile in the isocratic mode was used. The flow rate was 1.0 ml/min and the effluents were monitored at 215 nm. The retention time was 4.220 min. The detector response was linear in the concentration of 8-96 mcg/mL for Lafutidine. The respective linear regression equation being Y= 60153.876x + 9366.2787 for Lafutidine. The Limit of Detection (LOD) and The Limit of Quantification (LOQ) were 0.08 mcg and 0.24 mcg respectively for Lafutidine. The percentage assay of Lafutidine was 99.50 %. The method was validated by determining its accuracy, precision and system suitability. The results of the study showed that the proposed RP-HPLC method is simple, rapid, precise and accurate, which is useful for the routine determination of Lafutidine in bulk drug and in its pharmaceutical dosage forms.
