Abstract

Purpose: The objective of this study is to evaluate the bioequivalence of generic sitagliptin tablets from different manufacturers using in-vitro dissolution study under biowaiver conditions through UV Spectroscopy, and compare them with the innovator brand.
Materials and Methods: The dissolution media consisted of three different buffers with varying pH levels, including HCl Buffer pH 2.0, Phosphate Buffer pH 4.0, and Phosphate Buffer pH 7.2. The dissolution process was conducted using a USP type-2 dissolution apparatus with a 900 ml basket. The rotational speed of the paddle was set at 50 RPM, while maintaining a temperature of 37.5°C +/- 2°C. Samples were collected at four different intervals as recommended by the USFDA, which were 15, 30, 45, and 60 minutes.
Results: Validation parameters such as Accuracy, Precision, Linearity, LOD, and LOQ were assessed. The dissolution profiles exhibited no significant variability between different brands and within the same brand. Furthermore, the dissolution results of all tablet formulations, including the innovator brand, were analysed using the difference factor (f1) and similarity factor (f2).
The findings from this study indicate that both generic brands of sitagliptin tablets meet the USFDA dissolution specifications and can be considered interchangeable.
