Abstract
A simple, precise, rapid and economic method was developed for the simultaneous determination of Sitagliptin and Metformin HCl in bulk and dosage form. UV spectrophotometric method involves first order derivative spectroscopy using 238.5 nm & 216.0 nm as zero crossing points for Sitagliptin and Metformin HCl respectively. For spectrophotometric method, 0.1 N NaOH was used as a solvent. Linearity was observed in concentration range of 10-100 µg/ml of Sitagliptin and 2-20 µg/ml Metformin HCl. Results of analysis were validated statistically and by recovery studies.
