Development and Validation of UV Spectrophotometric Method for Simultaneous Estimation of Metformin HCl and Repaglinide in Pharmaceutical Formulation
Abstract
Objective: A new, simple, rapid, accurate and economical method have been developed for the simultaneous estimation of Metformin HCl and Repaglinide in formulation.
Method: The absorbances of both the drugs were determined at 238 nm and at 294 nm. The linearity was observed in the concentration range of 2-100 µg/ml and 1-35 µg/ml for Metformin HCl and Repaglinide respectively. The method was validated as per ICH guidelines.
Result: The recovery of Metformin and Repaglinide was found in the range of 98.24 ± 0.325 to 100.25 ± 0.756.
Conclusion: The proposed method was accurate, reproducible and economical and can be used successfully for quantitative estimation of Metformin HCl and Repaglinide in bulk and tablet dosage form.
