摘要

背景本研究建立并验证了一种紫外分光光度法,用于同时测定药物剂型中氢溴酸替格列汀(TEN)和盐酸吡格列酮(PIO)的含量。该方法在 243 nm 波长处测定 TEN 的吸光度,在 265 nm 波长处测定 PIO 的吸光度。该方法在 2-25 µg/ml 浓度范围内对 TEN 和 PIO 具有线性关系,相关系数接近 1。精密度研究显示 RSD%值较低,表明重复性极佳,日内和日间变异性极小。回收率研究证实了该方法的准确性,结果在 98-102% 的范围内。该方法灵敏度高,LOD 和 LOQ 值低。稳健性测试表明该方法在不同条件下具有稳定性和一致性。结论所开发的紫外分光光度法为同时估算药物制剂中 TEN 和 PIO 的含量提供了一种简单、灵敏、经济的解决方案。该方法适用于片剂的常规分析和质量评估。

Development and validation of a UV spectrophotometric method for simultaneous estimation of teneligliptin hydrobromide hydrate and pioglitazone hydrochloride in pharmaceutical dosage form

Background

This study presents the development and validation of a UV spectrophotometric method for the simultaneous estimation of teneligliptin hydrobromide hydrate (TEN) and pioglitazone hydrochloride (PIO) in pharmaceutical dosage forms. The method measures absorbance at 243 nm for TEN and 265 nm for PIO. Validation was conducted according to ICH guidelines, covering specificity, linearity, range, precision, accuracy, limit of detection, limit of quantification, and robustness.

Results

The method exhibited linearity in the 2–25 µg/ml concentration range for both TEN and PIO, with correlation coefficients close to 1. Precision studies showed low % RSD values, indicating excellent repeatability and minimal intra- and inter-day variability. Accuracy was confirmed through recovery studies, with results within the 98–102% range. The method demonstrated sensitivity with low LOD and LOQ values. Robustness testing showed stability and consistency under varying conditions. Analysis of tablet formulations confirmed the accurate quantification of both drugs.

Conclusion

The developed UV spectrophotometric method offers a simple, sensitive, and cost-effective solution for the simultaneous estimation of TEN and PIO in pharmaceutical formulations. It is suitable for routine analysis and quality assessment of tablet dosage forms.
