- 102 g of the nano-solubilized porous article prepared in Example 1 was placed in a polyethylene bag, and then 20 g of croscarmellose sodium, 102 g of low substituted hydroxypropylcellulose (LHPC LH11), 80 g of microcrystalline cellulose, and sprayed mannitol (Pearlitol SD) And the mixture was mixed at a speed of about 60 rpm for 5 minutes. 6 g of sodium stearyl fumarate in an amount of 40 mesh was added thereto and mixed at a speed of about 60 rpm for 3 minutes. Tablet (total 4000 tablets) was prepared by tableting the mixture so that the total weight per one tablet was 107.5 mg and the hardness was 4 to 8 kp.
- a nano-solubilized porous article was prepared by the ingredients and contents shown in Table 5 below. That is, the nano-solubilized porous article was placed in a polyethylene bag, and then croscarmellose sodium, low substituted hydroxypropyl cellulose (LHPC LH11), microcrystalline cellulose, and sprayed mannitol (Pearlitol SD) For 5 minutes. To this was added 40 ml of apple stearyl fumarate in 40 mesh and mixed at a speed of about 60 rpm for 3 minutes. The tablets were prepared by kneading the mixture so as to have a hardness of 4 to 8 kp, corresponding to the total weight per tablet shown in Table 5.

- Example 30 The tablets prepared in Example 30 and comparative dissolution tests on Abodart ( TM ), a marketed formulation, were performed.
- the dissolution test conditions were as follows: paddle rotation speed 5 rpm, temperature 37.0 ⁇ 0.5 ° C, eluant 900 ml of pH 1.2 solution containing 0.15% SLS (sodium lauryl sulfate). 5 ml of each sample was taken at 5, 10, 15, 30, and 45 minutes while performing the dissolution test under the dissolution test conditions, and the amount of dutasteride was analyzed by HPLC under the following conditions.
