Objective:To study the therapeutical mechanism of Feiyan Chuansou Oral Liquid (FCOL) in treating infantile acute respiratory tract infection. Methods: Clinical and experimental studies with FCOL in treating infantile acute respiratory tract infection. Results: The clinical result showed that the antitussive, expectorant, anti-asthmatic effect and resolution of dry and moist rale and wheezing of FCOL were significantly better in treatment group than those in the control group (P < 0. 05 ).Animal experimental results also showed that antitussive, expectorant, anti-asthmatic effect of FCOL were significantly better than those of the control group (P < 0. 05 - 0.001 ).Bacteriostatic test in vitro showed that FCOL could inhibit streptococcus pneumoniae, kleb siella pneumoniae, influenza bacilli and staphy lococcus aureus. Antivirologic test showed that FCOL could inhibit completely the influenza virus and respiratory syncytial virus. Conclu sion: FCOL is an effective preparation intreating infantile acute respiratory infection.
