The effect of particle shape and morphology on inhalation efficiency has been investigated. Carrier and drug model particles are formulated with a number of different surface morphology. Flowability, aerosolization and deposition behavior of particles with similar size range are investigated through in vitro experimentations. This study successfully optimizes that pollen-shape particle with fibrous surface morphology as optimum particle shape with favorable characterizing properties.
