Title: Anti-influenza medicine
Inventor: KIDO HIROSHI
IPC: A61K31/137
Filed: 2002-09-03
Abstract: PROBLEM TO BE SOLVED: To provide a therapeutic and prophylactic agent for the infection of influenza virus. SOLUTION: The anti-influenza medicine contains, as the active ingredient, ambroxol, bromhexine or pharmacologically acceptable salts thereof. The medicine has an anti-influenza effect via the promotion of the secretion of a biological anti-influenza virus factor contained in the airway fluid. The medicine inhibits 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. The medicine also inhibits the growth of an influenza virus in the airway by promoting the secretion of mucosal immunity substances IgA and IgG. The medicine further inhibits the release of inflammatory cytokines in the airway.
