Spectrophotometric determination of repaglinide in tablet dosage forms

A simple visible spectrophotometric method has. been developed for the estimation of repaglinide in tablet formulations. Beer's law is obeyed in the concentration range of 5-50 I¼g/ml of repaglinide. The method is simple, precise and accurate for pure analyte with recovery of 99.5-99.9%. It does not require any separation of soluble excipients present in tablets, as they do not interfere in the estimation.
