Characterization of DPI formulations using a powder rheometer helps developers understand volumetric dosing and aerosolization performance.

Finding in vitro methods to measure a number of powder properties that correlate with performance can enhance the industry’s ongoing learning process and can be essential for successful commercial production. Powder characterization techniques such as powder rheometry, which has proven itself an excellent method for quantifying aeration and fluidization behavior, therefore, provides an important tool for understanding and controlling dry powder performance.
