After the ezetimibe wet granules were prepared in the same manner as in Example 1, the ezetimibe wet granules were mixed with each simple rosuvastatin mixture, and the resulting mixture was then tableted, thereby preparing composite tablets(Example 5 and Comparative Examples 5, 6, and 7).

  • the composite tablets of Comparative Example 3 including a water-insoluble diluent having a relatively small particle size in the rosuvastatin mixture portion, had an improved dissolution rate, but poor flowability due to a relatively large angle of repose. Flowability affects tableting properties of granules, and low flowability may lead to a large deviation in mass among tablets and low production efficiency, which would thereby render such mixtures unsuitable for mass production.
  • the composite tablets of Comparative Example 4 including a water-insoluble diluent having a relatively large particle size in the rosuvastatin mixture portion were found to have good flowability but a large deviation in dissolution rate.
  • the composite tablets of Comparative Example 4 were found to exhibit a profile of delayed dissolution in simulated gastric fluid, relative to the composite tablets of the other examples.
  • the initial dissolution rate i.e., the release of ezetimibe in gastric juice
  • the composite tablets of Comparative Example 4 are expected to have a low bioavailability in practice due to their low initial dissolution rate.
