Aerodynamic particle size distribution (APSD) is an important item for in vitro quality assessment of inhalation products. The cascade impactor method is an internationally recognized method for the determination of APSD of aerosols, and it has been recorded in Multinational Pharmacopoeia. The method has important guiding significance for the research and development of generic drugs and innovative drugs for inhaled products by simulating the deposition of aerosols through the respiratory tract to different parts of the lungs in vitro. In this paper, the main structures and applications of the two-stage liquid impactors, multi-stage liquid impactors, Marple Miller impactors, Anderson cascade impactors and the new generation impactors contained in the current domestic and international pharmacopoeia are reviewed.
