Abstract

The invention relates to a compound liquorice tablet and a preparation process thereof. The compound liquorice tablet comprises the following raw materials: liquorice root extracts, opium powder, camphor, star anise oil, sodium benzoate, an adsorbent and a corrective. The preparation process comprises the following steps: adding the adsorbent in the raw material composition, and hiding special foul smell of the camphor and the star anise oil by adopting an adsorption method to eliminate the foul smell; adding the corrective in the raw material composition to enable the compound liquorice tablet to have satisfactory mouthfeel. Therefore, the compound liquorice tablet prepared by the invention is suitable for being taken orally, excellent in mouthfeel, good in clinical effects, and high in bioavailability. Meanwhile, through the improvement on the process, especially, a manner of performing direct tabletting on powder is adopted, so that the compound liquorice tablet is remarkably improved in process level, stable in quality and stable in effect; the production cost of the product is further reduced, and the tablet can serve patients better.

Problems solved by technology

After oral administration, a small amount of morphine in the opium powder is absorbed through the gastrointestinal tract, and then enters the liver through the portal vein. After the liver metabolizes, most of the morphine has been lost, which eventually leads to poor clinical efficacy of compound licorice tablets.

[0004] 2. In Compound Licorice Tablets, camphor and star anise oil have a special stench. Most users can’t accept it or experience nausea and vomiting. Therefore, oral administration is changed to swallowing, which also seriously affects its therapeutic effect.

[0005] 3. In the preparation of traditional compound licorice tablets, β-cyclodextrin is mostly used to clathrate two components such as camphor and star anise oil, which greatly reduces the odor of camphor and star anise oil. However, this The way of inclusion also causes a large loss of volatile components, thereby reducing the efficacy of the drug

Moreover, the inclusion process conditions of β-cyclodextrin are relatively strict, and the production process is unstable, which affects the quality of the product
