- Dissolution tests were performed under the following test conditions for each of the capsules prepared according to Examples 4 to 14 and Comparative Examples 4 to 8.
- the capsules of Examples 4 to 14 were found to have a dissolution rate of 13-34%, which is defined in the US Pharmacopoeia, and a variation in dissolution rate of 3.5% or less.
- Comparative Examples 4 and 8 did not meet the criteria (13 to 34%) prescribed by the US Pharmacopoeia, while Comparative Example 5, although the average dissolution rate satisfies the lower limit of the US Pharmacopoeia standard, There was a value deviating from, and Comparative Examples 6, 7 and 8, unlike Examples 4 to 14, the elution rate was 7.0% or more, it was not good uniformity between products.
- Test method follows the Uniformity of Dosage Unit of USP Tamsulosin Hydrochloride Capsule.
- capsules prepared in Examples 4 to 14 had a very good content uniformity between products at a level suitable for the content uniformity of 15 or less prescribed by the US Pharmacopoeia, which is the present invention.
- capsules containing pellets satisfying the range of the ratio of the particles having a particle size of about 0.50 mm to 0.85 mm in the range of about 50 to 100% by weight, and the particles having a particle size of about 0.50 mm or less to about 15% by weight are excellent in content uniformity. Shows.
- the capsules of Comparative Examples 6 to 8 had a significant change in their contents for each sample, which was inconsistent with the standards prescribed by the US Pharmacopoeia. This resulted in pellets having a particle size of 0.50 mm or less and pellets of 0.50 mm or more not well mixed with each other, so that the content uniformity was determined to be 16 or more, which is unsuitable to the standard prescribed in the US Pharmacopoeia.
- Tamsulosin hydrochloride-containing sustained-release pellets were prepared in the same manner as described in Example 1 using the prescription according to Table 6 below.
- a tadalafil tablet was separately prepared. Specifically, the wet granules were mixed using a high speed mixer with a composition as shown in Table 7 below, and then the binder solution was added and fed. The granules were dried and then granulated using a fluid bed dryer to prepare wet granules. The wet granules were mixed with excipients in the post-mixing unit and finally mixed with magnesium stearate. The mixture was compressed into tablets using a circular punch having a diameter of 5.5 mm using a rotary tablet press (GRC-18; Sejong Machinery, Korea). Then, the tadalafil tablet prepared above was coated by using Opadry II Yellow dispersed in purified water as a coating solution.
- the obtained tamsulosin sustained-release pellets and tadalafil tablets were filled into hard capsule No. 1 based on gelatin, thereby preparing a composite capsule containing 0.4 mg of tamsulosin and 5 mg of tadalafil.
- the photograph taken out of the contents including tamsulosin and tadalafil of the composite capsule prepared as described above is shown in FIG. 3.
