The formulation factors of influencing the aerosolizing and deposition properties of dry powder inhalation / 国际药学研究杂志

Recently, dry powder inhalation (DPI) has become a hotspot in the research area of pulmonary drug delivery (PDD). With the development of drug micronization technology and the emergence of innovative inhaler device, DPI has now been widely applied. This article introduces the formulation composition of DPI, which consists of micronized drug particles, carrier and inhaler device, and the formulation factors of influencing the aerosolizing and deposition properties are emphatically reviewed.
