    • The present invention relates to a quick disintegrating tablet in buccal cavity, comprising: a mixture, comprising a drug, a sugar (A), and an amorphous sugar (B), and after it is forming a tablet, it is humidified and dried. In particularly, the present invention relates to a quick disintegrating tablet in buccal cavity comprising: a mixture; comprising a drug, a sugar (A), and an amorphous sugar (B) which an amorphous-forming sugar in crystalline state is dissolved in a medicinally permitted solvent, the amorphous sugar is obtained from this solution by removing the solvent, and after it is forming a tablet, and it is humidified and dried. The tablet in the present invention is to provide stability against moisture at preserved, because the amorphous sugar changed to the crystalline state in a nonreversible reaction after it is humidified and dried in a manufacturing process. The tablet in the present invention is to further provide a design for the pharmaceutical preparation with respect to the stability of a drug, because the tablet is manufactured by one kind of a sugar and an amorphous sugar. Furthermore, the tablet in the present invention is to provide a production process by utilizing a common granulating machine and by utilizing a common tablet machine.
    • 本发明涉及颊腔中的快速崩解片,其包含:包含药物,糖(A)和无定形糖(B)的混合物,在形成片剂之后,将其加湿干燥。 特别地,本发明涉及颊腔中的快速崩解片剂,其包含:混合物; 包含药物,糖(A)和无定形糖(B),其中结晶状态的无定形形成糖溶解在药物允许溶剂中,通过除去溶剂从该溶液获得无定形糖,之后 正在形成片剂,并且被加湿和干燥。 本发明中的片剂是为了提供在保存的水分中的稳定性,因为无定形糖在制造​​过程中被加湿干燥后,在不可逆反应中变为结晶状态。 本发明的片剂是为了进一步提供关于药物的稳定性的药物制剂的设计,因为片剂由一种糖和无定形糖制造。 此外,本发明中的片剂是通过利用普通的造粒机和利用普通的压片机来提供制造方法。

    • The present invention relates to enteric sustained-release fine particles of tamsulosin or its salt that can be contained in tablets that disintegrate in the buccal cavity and a manufacturing method thereof. In further detail, the present invention relates to enteric sustained-release fine particles for tablets that disintegrate in the buccal cavity, which comprise (1) tamsulosin or its salt and at least (2) an enterosoluble substance, and when necessary contain (3) a water-insoluble substance, and which have the following characteristics: 1) a particle diameter of approximately 5 to 250 nullm 2) when dissolution tests are performed on tablets that disintegrate in the buccal cavity containing these particles by dissolution testing methods cited in the Japanese Pharmacopoeia, a) the dissolution rate of tamsulosin or its salt at a pH of 1.2 two hours after starting tests is 25% or less b) the time when 50% of the tamsulosin or its salt has dissolved at a pH of 6.8 is 0.5 to 5 hours, and a manufacturing method thereof.
    • 本发明涉及可以包含在颊腔中分解的片剂中的坦索罗辛或其盐的肠溶缓释微粒及其制造方法。 更详细地说,本发明涉及在颊腔中崩解的片剂的肠溶缓释微粒,其包含(1)坦洛新或其盐和至少(2)肠溶性物质,并且在必要时包含(3) 一种水不溶性物质,具有以下特征:1)粒径约5〜250μm2)当对含有这些颗粒的颊腔分解的片剂进行溶解试验时,通过日本的溶出试验方法 药典,a)在开始试验后两小时pH2.2时,坦索罗辛或其盐的溶解速率为25%以下b)当pH值为6.8时,坦索罗辛或其盐50%溶解的时间为0.5〜 5小时及其制造方法。
