(41) Results are summarized in Table 2 below.

(43) As is clearly understood from data of Table 2, the tablets tended to increase in hardness with an increase in compression pressure when the active ingredient particles had a D50 of 10 m or less (a maximum particle diameter of 10 m or less in 50% (v/v) of the active ingredient based on the total amount of the active ingredient) and a D90 of 25 m or less (a maximum particle diameter of 25 m or less in 90% (v/v) of the active ingredient based on the total amount of the active ingredient).

(44) In contrast, the tablets of the Comparative Examples did not significantly increase in hardness although compressed at increased compression pressures. For example, even at a compression pressure of 800 kgf, the tablets of the Comparative Examples were found to have a hardness of approximately 7 kp or less, which was similar to the hardness of the tablets of Examples compressed at a compression pressure of 300 kgf.

(45) It is thus understood from the results that when the active ingredient in the tablet has the specific particle size distribution which is a D50 of 10 m or less and a D90 of 25 m or less, the fimasartan potassium trihydrate particles can be of high compressibility so that they can be more greatly compressed with an increase in compression pressure, which makes it possible to easily control the hardness and disintegration time of the tablet and to decrease the friability of the tablet to 1% or less. Hence, the method of the present invention allows tablets to be homogeneous in physical properties even in mass production.

(46) To the contrary, as shown in Comparative Examples, when the fimasartan potassium trihydrate has a particle size distribution of a D50 greater than 10 m and a D90 greater than 25 m, their compressibility is poor, making it difficult to manufacture a tablet having sufficient hardness even at a high compression pressure. With such a particle size distribution of the active ingredient particles, there is difficulty in controlling the hardness and disintegration time of the tablet, and decreasing friability to 1%. As a result, non-uniform physical properties were detected over the tablets manufactured on a mass scale, thus degrading the product quality.

Test Example 2

(47) Granules prepared in the Examples and the Comparative Examples were assayed for density and Can's index. Density was measured according to Chapter 616 in General Chapter (Bulk density and Tapped density of powders) of the United States Pharmacopeia (USP). Carr's index was calculated according to the following equation:
Carr's index=100{1(Bulk density/Tapped density)}

(48) Results are summarized in Tables 3, below.

(49) TABLE-US-00003 TABLE 3 Assay for Density and Carr's index of Granules of Examples and Comparative Examples Properties of granules Preparation Bulk Density Tapped Density Carr's Examples Example (g/mL) (g/mL) index Example 1 Preparation 0.381 0.520 26.7 Example 1 Example 4 Preparation 0.379 0.516 26.6 Example 2 Example 7 Preparation 0.381 0.515 26.0 Example 3 Example 10 Preparation 0.380 0.517 26.5 Example 4 Example 13 Preparation 0.382 0.515 25.8 Example 5 Comparative Preparation 0.401 0.503 20.3 Example 1 Example 6 Comparative Preparation 0.403 0.495 18.6 Example 4 Example 7 Comparative Preparation 0.409 0.482 15.1 Example 7 Example 8 Comparative 0.469 0.532 11.8 Example 10

(50) As is clearly understood from data of Table 3, the granules has higher Carr's index when the active ingredient particles had a D50 of 10 m or less (a maximum particle diameter of 10 m or less in 50% (v/v) of the active ingredient based on the total amount of the active ingredient) and a D90 of 25 m or less (a maximum particle diameter of 25 m or less in 90% (v/v) of the active ingredient based on the total amount of the active ingredient) compared to those of the active ingredients having the D50 value of exceeds 10 m.

(51) When the Carr's index is increased, the compressibility is increased. Thus, it is confirmed that the granules including the fimasartan potassium hydrate having a D50 of 10 m or less and a D90 of 25 m or less superior compressibility.

Comparative Example 29

(108) A tablet was prepared in the same procedure as in Example 1, with the exception that the fimasartan potassium trihydrate was not used, 72 mg of lactose monohydrate was used and the compression was carried out at a compression pressure of 500 kgf.

Comparative Example 30

(109) A tablet was prepared in the same procedure as in Example 1, with the exception that the fimasartan potassium trihydrate was not used, 72 mg of lactose monohydrate was used and the compression was carried out at a compression pressure of 800 kgf.

Test Example 6

(110) Tablets prepared in the Comparative Examples 29 and 30 were assayed for hardness, disintegration time, and friability the same as those of TEST EXAMPLE 1.

(111) Results are summarized in Table 7 below.

(112) TABLE-US-00007 TABLE 7 Assay for Hardness, Disintegration Time and Friability of Tablets of Comparative Examples 29 to 30 Compression Pressure Hardness Disintegration Friability Examples (kgf) (kp) Time (min) (%) Comparative 500 5.8 2.75 2.4 Example 29 Comparative 800 6.1 3.83 2.1 Example 30

(113) As is clearly understood from data of Tables 4 to 6, the tablets according to Examples 16 to 45 exhibited superior hardness, disintegration time, and friability to those of comparative Examples 11 to 28 although the additives included in the tablet is changed from lactose monohydrate and hydroxypropyl cellulose into D mannitol (Examples 16 to 25), corn starch (Examples 26 to 35) and hydroxypropylmethyl cellulose (Examples 36 to 45), respectively.

(114) Additionally, as shown in Table 7, when tablet was prepared without the active ingredient of the fimasartan potassium trihydrate, hardness, disintegration time and friability are inferior to those of tablets according to Examples 1 to 45 including the active ingredient of the fimasartan potassium trihydrate.

(115) Thus, it is confirmed that the properties of the tablet are not greatly affected by the additives when the amount of the active ingredients of fimasartan potassium trihydrate is high in the tablet.
