Sitagliptin is a novel oral hypoglycemic drug of dipeptidyl peptidase-4 inhibitor class. Dipeptidyl peptidase-4 inhibitors represent a new therapeutic approach for the treatment of type 2 diabetes that functions to stimulate glucose-dependent insulin release and reduce glucagons levels. This is done through inhibition of the inactivation of incretins, particularly glucagon-like peptide-1 and gastric inhibitory polypeptide), thereby improving glycemic control. Five new spectrophotometric methods have been established for the determination of Sitagliptin tablets. SHIMADZU Model No. UV – 1800 double beam spectrophotometer with quartz cells was used for the proposed study Sitagliptin has shown absorption maxima at 267 nm in reagents such as phosphate buffers (pH 5.0 and 8.0), acetate buffer (pH 4.7), 0.1N NaOH and borate buffer (pH 9.0) Sitagliptin obeys Beer-Lambert’s law over the concentration range 5 - 100 µg/ml for all the above mentioned methods and all the methods were validated as per ICH guidelines. The methods are simple, precise, accurate and economical and can be used for the quantification of Sitagliptin tablets.
