ABSTRACT
To prepare and evaluate dry powder inhalation (DPI) of extraction of Trollius chinensis Bunge (TCB). Orthodox design was employed to optimize the parameters of spray drying to prepare micronized TCB powder, the DPI was prepared by mixing micronized TCB powder and lactose. The results showed that the fine particle fraction (FPF) and emitted dose (ED) of micronized TCB powder was (21.07 +/- 1.74)%, (75.31 +/- 21.05)%, respectively, and for DPI was (56.4 +/- 2.2)%, (95.9 +/- 3.0)%, respectively. Therefore, the prepared DPI meeted requirements in the Chinese Pharmacopeia, indicating a good application prospect.
