摘要

Particles of 0.01 to 20 ??m average diameter comprising tert-butyl (4R)-4-{[((1R)-2-[(1-benzylpiperidin-4-yl)amino]-1-{[(cyclohexy lmethyl)thio]methyl}-2-oxoethyl)amino]carbonyl}-1,3-thiazolidine -3-carboxylate. Preparations comprising the particles excel in transition into the lungs by inhalation and excel in dispersibility as particles, so that handling thereof is easy to thereby enable use of the compound as transpulmonary preparations.
