Outline of Final Research Achievements

One of the challenging issues of development of inhalation formulation is scaling up process. While unique and efficient inhalation formulations have been developed and reported by researchers in lab scale,the scaling up of these formulations was difficult due to several reasons. Our group developed two-solution mixing type spray nozzle previously. The spray nozzle can prepare nanocomposite particles that are microparticles containing drug nanoparticles, and its process is suitable for scaling up. In the current research, we attempted to develop unique inhaled formulations for pulmonary patients through 2-solution mixing type spray nozzle.
