| 摘要 |
Disclosed herein is a use of a composition comprising ambroxol, bromhexin or a pharmaceutically acceptable salt thereof in the manufacture of a medicament to treat influenza virus-infectious diseases, wherein the composition shows its anti-influenzal function through promoting the secretion of a bio-factor showing anti-viral function against influenza viruses and contained in a liquid secreted from the respiratory tract. These drug compositions are characterized by inhibiting the growth of an influenza virus in the airway by promoting the secretion of an inhibitor for a protease in the airway which induces the infectivity of the influenza virus. These drugs are also characterized by inhibiting the growth of an influenza virus in the airway by promoting the secretion of mucosal immunity substances IgA and IgG. These drugs are further characterized by inhibiting the release of inflammatory cytokines in the airway.
