Spectrophotometric Method Development and Validation for Estimation of Ibuprofen and Famotidine In the pharmaceutical formulation

Ibuprofen is a nonsteroidal anti-inflammatory agent (NSAIA) with analgesic and antipyretic properties. Famotidine is a competitive histamine H2-receptor antagonist, is used to treat gastrointestinal disorders such as gastric or duodenal ulcer. The aim of the present research work was to develop accurate and rapid Area under Curve Method to determine Ibuprofen and Famotidine in combined dosage form. The Area under Curve method, wavelength range selected are 259-269 nm for Ibuprofen and 282-292 nm for Famotidine respectively. The developed method was obeyed the Beer’s law and was f ound linearity range between 80-640 μg/ml for IBU and 2-22 μg/ml for Famotidine; while the correlation coefficient were 0.9985 for Ibuprofen and 0.9982 for Famotidine. Parameters such as linearity, accuracy, precision, LOD and LOQ values were used for validation of the methods as per ICH guidelines for both methods. Intra and inter-day precision %RSD values were less than 2%. This method is found suitable for day to day analysis of Ibuprofen and Famotidine in combined dosage form.
