Shown (Table 3).
- the fine particles C have high mucoadhesive properties in the particles themselves, and even when diluted to the concentration of commercial preparations and in viscous suspension media, they have higher mucoadhesive properties than conventional FP drug particles. It was confirmed to show sex.
- microparticle C Compared to FP particles contained in commercially available preparations, microparticle C was considered to have a very high retention in the nasal mucosa, so it remained over time at the administration site of the test preparation prepared from millicaret or microparticle C. We compared the transition of quantity. The dosage was 25 ⁇ g / mouse for the test preparation prepared from millicaret and 30 ⁇ g / mouse for the test preparation prepared from microparticle C. The results are shown in Figure 3.

Was showing.
- the residual amount of the fine particles C at 24 hours after the administration was smaller than the residual amount at 12 hours after the administration, it was considered that the risk of residual and accumulation of these particles was low.
- the group of test preparations prepared from millicaret 1 of 3 cases was observed at 12 hours after administration, and 2 of 3 cases were below the lower limit of quantification at 24 hours after administration.
- the lower limit of quantification of 0.2 ⁇ g was substituted, and all time points were expressed as the mean value and SD of 3 cases.
- the value at 24 hours after administration is not reliable as an absolute value, so in FIG. 3, the period from 12 hours to 24 hours after administration is shown as a broken line.
- radial particles are small and monodispersed. Therefore, in order to prevent aggregation, an aqueous solution in which polyvinyl alcohol (PVA) was added at 0.5% in the water for precipitation was prepared. This was added using a pump in the same manner as in 1-C above, to obtain FP radial needle crystals. The crystals had a needle-like crystal length distribution of 5 to 30 ⁇ m and an average particle size of about 15 ⁇ m. When suspended in water, it was dispersed in a monodispersed state. To these particles, pulverized mannitol was mixed at a ratio (weight) of 98 to obtain a powder preparation for pulmonary administration.
