Problems solved by technology

Although some AIVs have the ability to spread to humans, most of them are sporadic at present, and there is no large number of cases, indicating that there are individual differences in the susceptibility of human beings to influenza viruses

Abstract

The invention discloses buccal tablets for preventing influenza virus and application of the buccal tablets. The buccal tablets comprise glycoprotein of a SAalpha2-3Gal sugar chain structure and glycoprotein of a SAalpha2-6Gal sugar chain structure. According to the technical scheme, the buccal tablets have the advantages of directly acting on the mouth cavity and the throat, increasing the concentration of glycoprotein of the SAalpha2-3Gal sugar chain structure and the SAalpha2-6Gal sugar chain structure, neutralizing and inhibiting recognition of avian and human influenza virus on the human body upper respiratory tract cell surface specific receptor, and achieving the effect of preventing avian and human influenza virus infection; due to slow mouth dissolving, medicine can stay on the surface of the mouth cavity and the throat for a long time, and the medicine effect is continuously achieved.

Description

technical field [0001] The present disclosure generally relates to the field of antiviral lozenges, and in particular to lozenges and applications thereof for preventing avian and human influenza viruses. Background technique [0002] Avian influenza is an infectious disease of poultry caused by avian influenza viruses (AIV). AIV can be divided into high pathogenicity virus and low pathogenicity virus according to its pathogenicity. Viruses with high pathogenicity will cause a devastating blow to the poultry farming industry. In addition, there is a class of more harmful AIV, which shows low or no pathogenicity to poultry, but has high pathogenicity to humans, such as the H7N9 subtype. The World Health Organization judges whether an influenza pandemic is coming based on four conditions: 1) Humans have no immunity; 2) Can be transmitted from poultry to humans; 3) Can cause death of infected people; 4) Can be transmitted from person to person . At present, it has been foun...
