반응 단계

Compound A (24.8 g), sucrose (Osaka-Toka. Co., Ltd., 28.7 g), crystalline cellulose (Avicel PH-101, Asahi Kasei Corporation, 8.0 g) and L-HPC (LH-31, Shin-Etsu Chemical Co., Ltd., 12.5 g) were thoroughly mixed to give a dusting powder. Malic acid crystal (Wako Pure Chemical Industries, Ltd.) was sieved with a round sieve to give malic acid crystal on 30 mesh (aperture 0.50 mm). The malic acid crystal (150 g) was fed into a centrifugal fluidized-bed granulator (CF-mini, Freund Corporation) and coated with the above-mentioned dusting powder while spraying an aqueous solution (6 w/v %) of hydroxypropylcellulose (HPC-SL, NIPPON SODA CO., LTD.). The obtained spherical granules were dried under reduced pressure in a constant temperature vacuum drying oven (DP43, YAMATO SCIENTIFIC CO., LTD.) at 40° C. for 16 hr, and sieved with a round sieve to give granules at the range of 16-30 mesh (aperture 0.50-1.00 mm). The granules (450 mg) were filled in No. 0 gelatin capsules (Capsugel) to give capsules having the following composition per capsule.
