Problems solved by technology

[0002] Banlangen has the functions of preventing influenza, anti-virus, clearing away heat and detoxification, cooling blood and relieving throat, but the existing dosage forms are mostly granules, tablets, oral liquid, etc., and granules are inconvenient to carry and take. The local residence time of the pharynx and throat is short, which is not conducive to the elimination of pathogens in the oral cavity and pharynx, and it is difficult to relieve local inflammation, and the curative effect is not obvious
[0003] The patent document with the announcement number CN1233399C and the patent number 200310119261.7 discloses a effervescent tablet of Radix isatidis and its preparation method. The method adopts microwave extraction and alcohol precipitation to obtain the effective part of Radix Radix Radix, uses ethylene glycol to wrap the carbon dioxide source, and requires microwave Extraction, the process is more complicated, and the content of active ingredients in the prepared medicine is not high, which needs to be improved

Abstract

The invention relates to a Banlangen buccal tablet and a preparation method thereof. The Banlangen buccal tablet contains the following components: 80-120 parts of Banlangen, 10-45 parts of flavouring agent, 0.1-1 part of lubricating agent and 120-170 parts of golden buckwheat rhizome. The preparation method comprises the following steps of: during production, weighing the banlangen firstly, decocting twice by adding water, merging decoction, filtering, concentrating the filtrate until the density is 1.05-1.25g / cm<3>, adding ethanol to ensure that the content of the ethanol reaches 50-60 percent, standing, taking supernate, recycling the ethanol and concentrating to form an extract with the density of 1.30-1.33g / cm<3>; adding the flavouring agent and the lubricating agent, uniformly mixing, drying, crushing, adding ethanol granulations, drying for the second time until the water content ranges from 1.5 to 5 percent, and finally tabletting. The buccal tablet can be used for preventing and treating viral influenza, reaches the cure rate of 64.6 percent when used for treating acpuei pharyngitis, chronic pharyngitis, acute tonsillitis and other diseases, achieves the total effective rate of 97.6 percent, has good durative effect which is obviously better than that of like products, is convenient to take and is suitable for various crowds.
