Efficacy of Guaifenesin and Dextromethorphan Hydrobromide Granules in the Adjuvant Treatment of Infantile Acute Bronchitis

Objective： To observe the clinical efficacy and safety of guaifenesin and dextromethorphan hydrobromide granules in the treatment of child acute bronchitis. Methods： Totally 156 children with acute bronchitis were divided into two groups randomly, the control group was treated with routine anti-infection and inhalation therapy, while the observation group was treated with guaifenesin and dextromethorphan hydrobromide granules additionally. The improvement of cough, sputum, sputum viscosity and the other clinical symptoms, total effective rate and adverse drug reactions was studied and compared in the two groups. Results： The observation group showed significant improvement in acute bronchitis cough, sputum and sputum viscosity with clinical control rate of 52.56% , which was significantly higher than the control group （38.46%）. The total effective rate of the observation group was 89.74% , which was also significantly higher than that of the control group （69.23%）. The difference was statistically significant （P 〈 0.05 ）. There were no obvious adverse drug reactions in the two groups. Conclusion： Guaifenesin and dextromethorphan hydrobromide granules are effec- tive and safe in the adjuvant treatment of infantile acute bronchitis, which is valuable to be widely used in clinic.
