Embodiment 1

[0229] Example 1: Preparation of Tamsulosin Hydrochloride Orally Disintegrating Tablets

[0230] (1) Dissolve 80 g of tamsulosin hydrochloride and 80 g of hydroxypropyl methylcellulose in 2000 g of purified water. Microcrystalline cellulose microparticles (Celphere102, Asahi Kasei, average particle diameter is about 120 μm, more than 95% particle diameter is in the range of 50-150 μm) 4000g is put into fluidized bed granulator, wraps with this solution with lateral spraying method Clothing to obtain tamsulosin hydrochloride particles.

[0231] The fluidized bed granulator above and in the context of the present invention is the WBF-60 fluidized bed granulator produced by Chongqing Yingge Granulation Coating Technology Co., Ltd. When using this fluidized bed granulator for granulation and / or coating, according to different materials, the spray speed can usually be controlled in the range of 10-120g / min, and the spray air pressure can usually be controlled in the range of 0.5-...

Abstract

The invention relates to a tamsulosin orally disintegrating tablet composition with slow release performance. Concretely, the invention relates to an orally disintegrating tablet, which is a tablet obtained through pressing by using a tableting process. The tablet comprises a tablet base body and a plurality of coated micropills, wherein the tablet base body is prepared from a plurality of auxiliary materials; the coated micropills are basically uniformly dispersed in the tablet base body; the coated micropills comprise pill cores containing active ingredients and at least one layer of coatingcovering the surfaces of the pill cores. The invention further relates to a method for preparing the orally disintegrating tablet. The invention further relates to a method for improving the hardnessof the orally disintegrating tablet and improving the disintegrating performance. According to the method, the orally disintegrating tablet is pressed through a tableting process. The tablet comprises the tablet base body prepared from a plurality of auxiliary materials and a plurality of coated micropills basically uniformly dispersed in the tablet base bodies. The orally disintegrating tablet provided by the invention has excellent effects shown in the description in each aspect.

Description

technical field [0001] The invention belongs to the technical field of pharmacy, and relates to a preparation method of a highly selective α1A-receptor antagonist for treating benign prostatic hyperplasia, in particular to a method for preparing tamsulosin, more particularly to a A method for preparing an orally disintegrating sustained-release tablet composition of tamsulosin hydrochloride with excellent pharmaceutical effects. Background technique [0002] In order to improve the convenience of drug use and solve the medication compliance of specific indications and special patient populations, the pharmaceutical industry has developed a type of tablet that can be disintegrated into fine particles and accompanied by saliva to the stomach after being placed on the tongue. Such tablets are commonly referred to as orally disintegrating tablets or orally disintegrating tablets. These orally disintegrating tablets do not need to be chewed, swallowed whole, or taken with water....
