Falsified drugs are a growing problem and a great threat all over the world. Searching for easy, fast, not expensive and reproducible methods for identification of active pharmaceutical ingredients (APIs) is an important issue. The application of ATR-IR technique for identification of phosphodiesterase-5 inhibitors (PDE-5i) in falsified products from the Polish market has been demonstrated. Furthermore, the strategy of confirmation of the product's originality in a quick and easy way has been developed. The advantages of this application are: exceptional simplicity, very short measurement time, high selectivity in relation to structurally similar substances and almost no sample preparation. After validation, developed strategy has been successfully introduced into routine analysis. 相似文献
