Problems solved by technology

If the extraction process is unreasonable and unscientific, it will inevitably cause damage and loss of active ingredients, thereby affecting the quality and curative effect of the preparation
In addition, the disintegration time of the existing Yuanhu Zhitong Tablets is relatively long, especially after long-term storage, there is a phenomenon that exceeds the pharmacopoeia standard, and too long disintegration time will seriously affect the abs

Abstract

The invention discloses Yuanhu Zhitong Tablet and a preparation method thereof. The Yuanhu Zhitong tablet is composed of vinegar Corydalis and Angelica dahurica; the preparation method of the Yuanhu Zhitong tablet of the present invention is to ultrafinely pulverize 1/2 amount of Corydalis Corydalis, extract the remaining Corydalis Corydalis with compound enzymes, and perform supercritical extraction of Angelica dahurica; The invention has the advantages of more complete extraction of active ingredients, higher content, fast drug dissolution rate, high bioavailability and good stability through the improved process.

Description

technical field [0001] The invention relates to a medicinal preparation in the field of medicine, in particular to Yuanhu Zhitong Tablet and a preparation method thereof. Background technique [0002] Yuanhu Zhitong Tablets are listed in the Chinese Pharmacopoeia. Prepared from Corydalis Corydalis and Angelica dahurica, it has the effects of regulating qi, promoting blood circulation and relieving pain. It is used for stomach pain, hypochondriac pain, headache and dysmenorrhea caused by qi stagnation and blood stasis. [0003] At present, the preparation process of Yuanhu Zhitong Tablets basically follows the traditional process method, and a part of Angelica dahurica is crushed into fine powder; the rest of Angelica dahurica is crushed into coarse powder with vinegar Corydalis for extraction. Due to the open type pulverization of ordinary pulverizers, there will be disadvantages such as large particle size during granulation, which will cause heavy metal pollution, slow dr...
