Abstract

Objective To explore the efficacy and safety of different doses of budesonide mixed suspension atomization inhalation in children with post infectious cough,and provide reference for the rational use of budesonide.Methods One hundred and twenty children with post infectious cough aged 2-14 years old were selected and divided into three groups by random digits table method (40 cases in each group).Control group was treated with 4 mg once montelukast sodium chewable tablets for 2-5 years old children,or 5 mg once for 6-14 years old children.Low-dose group was treated 2 times/d with a dose of 0.5 mg budesonide mixed suspension diluted in normal saline to 4 ml based on control group and high-dose group was treated 2 times/d with a dose of 1.0 mg budesonide mixed suspension diluted in normal saline to 4 ml based on control group.The outcome of curative effects were recorded and analyzed after 7 days of treatment.Results The total efficacy rate was 70.0％(28/40),52.5％(21/40),35.0％(14/40) in high-dose group,low-dose group and control group after 3 days of treatment,and there was significant difference between high-dose group and control group (P＜ 0.01).The total efficacy rate was 92.5％(37/40),90.0％(36/40),72.5％ (29/40) in high-dose group,low-dose group and control group after 7 days of treatment,and there was no significant difference(P ＞ 0.025).Few adverse events associated with inhaled corticosteroids,such as thrush,sore throat,hoarseness were observed in three groups.Conclusions Budesonide mixed suspension atomization inhalation alleviates symptom of post infectious cough significantly with no obvious side effects,even in high-dose group which has a more outstanding efficacy.Therefore,this therapy is valuable in clinical application.
