Benchmarking of Particle Engineering Strategies for Nasal Powder Delivery: Characterization of Nasal Deposition using the Alberta Idealized Nasal Inlet

The objective of this study was to characterize nasal deposition and benchmark nasal powders manufactured by different particle engineering strategies, namely spray dried microparticles (SDM), chimeral agglomerates (CA) and blends, using the Alberta Idealized Nasal Inlet (AINI). The AINI method conditions were firstly optimized by selecting appropriate angle of actuation and flow rate. Then, six different formulations prepared with distinct polymers and particle engineering strategies were evaluated.
