An anti-influenzal agent comprises, as an effective component, ambroxol, bromhexin or a pharmaceutically acceptable salt thereof. This agent is characterized in that it has an anti-influenzal effect through the promotion of the secretion of biological factors, which possess influenza virus-proliferation-inhibitory effect and are included in the fluid secreted in the respiratory tract. It is also characterized in that it can inhibit the influenza virus-proliferation in the respiratory tract through promoting the secretion of substances capable of inhibiting proteases in the respiratory tract, which induce the influenza virus infection, that it can inhibit the influenza virus-proliferation in the respiratory tract through promoting the secretion of mucosal immune substances or IgA and IgG and that it can inhibit any release of inflammatory cytokines in the respiratory tract. The present invention also relates to an agent for treating or preventing influenza virus-infectious diseases.
一种抗流感剂包括作为有效成分的氨溴索、溴己新或其药学上可接受的盐。这种制剂的特点是,它通过促进呼吸道分泌液中含有的具有抑制流感病毒增殖作用的生物因子的分泌来发挥抗流感作用。本发明的另一个特点是,它可以通过促进呼吸道中能够抑制蛋白酶的物质的分泌来抑制流感病毒在呼吸道中的扩散,这些蛋白酶会诱发流感病毒感染;它可以通过促进粘膜免疫物质或 IgA 和 IgG 的分泌来抑制流感病毒在呼吸道中的扩散;它还可以抑制呼吸道中任何炎症细胞因子的释放。本发明还涉及一种用于治疗或预防流感病毒感染性疾病的制剂。
