A simple, precise and cost effective visible spectrophotometric method was developed for estimation of racecadotril in capsule dosage form. The method is based on the formation of drug into an orange colored species upon the addition of an acidified ferric chloride solution and the absorption maxima of these coloured species was found to be 456 nm. Calibration curve was linear over the range of 10 μg-2000 μg/ml. The % assay of drug was found to be 100.84%. The performance of the method was validated according to ICH guidelines. The method can be applied for determination of drug in its capsule dosage form without any interference from excipients. The proposed method is suitable for routine quality control analysis.
