Clinical and Experimental Study on Shuanghua Aerosol (双花喷雾剂)

Objective: To study the effect and mechanism of Shuanghua aerosol (SHA) in treating infantile upper respiratory tract infection. Methods: In the clinical study, 276 patients were randomly divided into two groups. The treated group was treated with SHA and the control group was treated with Shuanghuanglian aerosol (SHLA, 双黄连气雾剂). In the experimental study, the effects of SHA on anti-inflammation and anti-virus were observed. Results: The clinical total effective rate of SHA was 99.03% and its cure rate 65.38%, while those of the SHLA were 94.11% and 44.12% respectively, significant difference was shown between the two groups (P<0.01). Experimental study showed that SHA could inhibit the xylol induced ear swelling and the egg white induced paw swelling in mice obviously, and inhibit the proliferation of influenza virus in rat's lung. Conclusion: SHA has obvious anti-inflammatory and anti-viral effect, and has good curative effect in treating infantile upper respiratory tract infection.
