Abstract

The invention discloses a preparation method of a detoxicating tablet of cow-bezoar, and belongs to the technical field of Chinese medicament preparation. The method is reasonable in process flow setting, can be used for remarkably improving the production efficiency of the detoxicating tablet of cow-bezoar and reducing the heated time of realgar in the granulating process by adopting a one-step granulation method. The granulation efficiency is remarkably improved by increasing the density of extracted concentrate and spray liquid, so that the production efficiency of the detoxicating tablet of cow-bezoar is greatly improved, and the drying time in the granulating step is effectively reduced. According to the preparation method, the heated temperature of realgar and realgar-containing component in the drying process can be reduced, and the transformation amount of realgar to arsenic trioxide is effectively avoided, so that the production of toxic substances can be reduced, and the prepared product is safer and more reliable. The prepared product is high in effective component content and stable in quality by regulating the time of adding scutellaria baicalensis and decocting platycodon grandiflorum, liquorice, gyp and scutellaria baicalensis twice, and is in accordance with national standard.

Description

technical field [0001] The invention relates to a preparation method of Niuhuangjiedu tablets, in particular to a preparation method of Niuhuangjiedu tablets, and belongs to the technical field of preparation of Chinese patent medicines. Background technique [0002] Niuhuang Jiedu Tablets are developed from Niuhuang Jiedu Pills, a famous medicine with a history of 800 years. It is a famous prescription for clearing away heat and detoxifying. , with definite curative effect, it is still commonly used in clinical practice today, and it is a standing "drug for dispelling gunpowder" in many families. However, in recent years, there have been many reports on the safety problems caused by Niuhuangjiedu Tablets. Since the late 1990s, the Adverse Drug Reaction Monitoring Division of the Drug Evaluation Center of the State Food and Drug Administration has been concerned about the safety of Niuhuangjiedu Tablets. [0003] In "Chinese Pharmacopoeia", Niuhuang Jiedu Tablets are made o...
