Problems solved by technology

The products on the market have capsules and tablets, but the dosage forms of these two products are relatively backward, and the absorption and utilization of medicines are poor, so some researchers have carried out research, such as the patent application number is "03110877.6", the name is "Hydrochloride Hydrochloride". Rhizoma Intravenous Infusion, Injection and Production Process", the patent application number is "03110953.5", the name is "Bairui Hydrochloride Chewable Tablets and Production Technology", the patent application number is "200410023041.9", the name is "Bairui Dispersible Tablets" and production method” patent application; although injectables have high bioavailability, they are inconvenient to use, have many adverse reactions, high risk factor, and high cost; chewable tablets have a poor taste; dispersible tablets require a large amount of disintegrants, and the cost is high; In view of these circumstances, in order to improve the stability of the drug, it is necessary to find an effective therapeutic drug preparation with ideal therapeutic effect, reliable quality and reasonable dosage form to enrich the variety of dosage forms and meet the needs of the market.
