- An object of the present invention is to provide a particle comprising Compound 1, having excellent in-vivo transferability and good dispersibility, and a preparation having good operability comprising the same.
- the present inventors have conducted extensive studies, and as a result, by controlling the particle diameter of the particles containing Compound 1 to be about 0.01 to about 20 m, the dispersibility is improved. Furthermore, surprisingly, it was found that the absorption rate by transpulmonary inhalation administration was improved. In addition, the present inventors have designed to improve the absorption rate when inhaling Compound 1 by pulmonary force, and have found that the compound 1 can be made into an excellent preparation.

- a preparation comprising the particles according to any one of 1 to 7 above.
- Compound 1 A thiazolidine-3 carboxylate (hereinafter referred to as Compound 1) may be abbreviated as a particle of the present invention.
- the formulation for transpulmonary administration using the particles of the present invention exhibits a high in vivo transferability with a lung transfer rate of about 10 to about 100%, and thus can exhibit sufficient efficacy even at a low dose. It becomes.
- the particles of the present invention can be used at a low dose of Compound 1, it is possible to reduce the burden on the patient by reducing the dose for reasons such as reducing side effects.
- the "particle" containing Compound 1 may be a particle of Compound 1 alone or contains Compound 1, and is further selected from one or more selected from water-soluble polymer and phospholipid power.
- one or more saccharides may be added, and other preparation bases (such as saccharides) may be added to form a preparation.
- the "average particle size” represents a particle size that represents a particle group when the particle group also includes many particle forces having non-uniform diameters.
- the average particle diameter includes weighted averages such as a number average diameter, a length average diameter, an area average diameter, and a volume average diameter, and is not particularly limited, but in the present invention represents a volume average diameter.
- the average particle diameter in the particles of the present invention is preferably about 0.01 to about 20 m, more preferably about 0.03 to about 10 m, and still more preferably about 0.03 to about 5 m, particularly preferably about 0.1 to about 5 m.
- Sarakuko can eliminate the adhesion and cohesiveness of the particles themselves by incorporating phospholipids, water-soluble polymers, etc. into the particles of the present invention. In addition to being excellent in transpulmonary inhalation, compound 1 can be delivered to a living body at a high rate by transpulmonary administration.

- aerodynamic particle diameter As a standard for achieving a strong lung transfer rate, for example, aerodynamic particle diameter (aerodynamic diameter) can be mentioned. Aerodynamic particle size is defined as the particle size of a particle that has the same settling velocity as the particle, has a density of lg / cm 3 and is spherical. This can be obtained using the difference in the settling distance of the particles and the difference in inertia when the particles are accelerated.
- the Andersen cascade impactor used in the Examples is collected by aerodynamic particle size and collected, for example, when suctioned at a flow rate of 28.3 LZ, the deposited particles on each site.
- Aerodynamic particle size is 10 ⁇ m or more for throat and pre-separator, 9.0 to 0 for Stage 0: LO.O / zm, 5.8 to 9.0 m for Stage 1, and 4. for Stage 2. 7 to 5.8 m, Stage 3 to 3.3 to 4.7 m, Stage 4 to 2.1 to 3.3 m, Stage 5 to 1.1 to 2.1 m, Stage 6 to ⁇ 0 65 to: L 1 m, ⁇ on stage 7 0.65 to 0.43 m, with filter less than 0.43 m.
