Aerodynamic particle size distribution (APSD) is a vital quality attribute for inhaled medications. Currently, next-generation impactor analysis serves as the industry gold standard for this task. However, the process often feels slow because it requires high-performance liquid chromatography (HPLC) for quantitation. Consequently, researchers are developing new methods to increase efficiency. For instance, digital image segmentation now offers a promising way to derive APSD metrics more quickly. Because of this advancement, scientists can process more samples in less time.
This novel method uses image analysis to measure the size of active pharmaceutical ingredients. Specifically, the technology provides enough resolution to distinguish between different particle sizes within lactose blends. Furthermore, the findings show that image-based results are very similar to those from traditional HPLC. Therefore, researchers can achieve faster results without sacrificing accuracy. In addition, this technique handles stressed blend samples effectively. Moreover, it simplifies the pharmaceutical testing workflow significantly. In conclusion, this study establishes that high-throughput image analysis is feasible for APSD determination.
APSD stands for Aerodynamic Particle Size Distribution. It tells us the size of drug particles, which determines where they land in the respiratory tract.
While HPLC remains the current regulatory standard, image analysis offers a much faster alternative for next-generation impactor analysis while producing comparable results.
