In other words, the formulation containing only titanium oxide (Comparative Example 2) was able to prevent the formation of the ring-closed product, but not the 5-keto product. In addition, the formulation containing only yellow No.
- Example 9 was the preparation showing the most excellent light stability.
- Production Example 2 Pitapastatin calcium 200g, Magnesium aluminate metasilicate 250g, Lactose 477 8g, D-mannitoleol 5000g, Low-substituted hydroxypropinoresenorelose 1200g, Acid-titanium 240g (acid-titanium NA-65: Toho Titanium) Then, after preparing a homogeneous powder mixture, it was granulated by fluidized bed granulation. This granule is pre-dissolved in 2000 mL of purified water with 2910 g of hydroxypropyl methylcellulose and 12 g of Sunset Yellow FCF (Yellow No. 5: Saneigen F.F. It was.
- This granule was mixed with 120 g of magnesium stearate and tableted to obtain a tablet containing pitapastatin calcium (1 tablet 120 mg, diameter 7. Omm).
- 480 g of hydroxypropylmethylcellulose and lOOg of triethyl citrate are dissolved in 60 OO mL of purified water, and then film coating is performed in a conventional manner with a solution in which 60 g of acid titanium and 60 g of hydrous diacid silicate are dispersed. Then, film-coated tablets (1 tablet 127 mg, diameter 7. lm m) were obtained.
