In Table 2, Examples 1, 2 and 3 comprising an ethyl acrylate / methyl methacrylate copolymer as compared to the enteric pellets of Comparative Example 2 comprising no ethyl acrylate / methyl methacrylate copolymer (water-insoluble polymer) and It was found that the enteric pellet of Comparative Example 1 had a higher dissolution rate of duloxetine hydrochloride at each time point. Therefore, it was suggested that non-enteric polymers such as insoluble polymers have the effect of improving the dissolution properties of drug salts in enteric drug salt compositions.
Moreover, compared with the enteric pellet of the comparative example 1 whose amount ratio of the non-enteric polymer with respect to an enteric polymer is low, the amount ratio of the non-enteric polymer with respect to the enteric polymer is high. It was also found that the soluble pellets had a significantly higher dissolution rate of duloxetine hydrochloride at each time point. Therefore, it was suggested that the amount ratio of the non-enteric polymer to the enteric polymer in the preparation should be a certain low value or more in the above effect.
In addition, compared with the enteric pellet of Example 3 having the highest ratio of the non-enteric polymer to the enteric polymer, the enteric pellet of Examples 1 and 2 has a dissolution rate of duloxetine hydrochloride of 45 minutes. It was also found to be significantly higher at each subsequent time point. Therefore, it was suggested that the amount ratio of the non-enteric polymer to the enteric polymer in the preparation should be lower than a certain high value in the above effect.
