简要总结
The purpose of this study is to determine if there is comparable efficacy between carbocisteine and a protective cough syrup from natural ingredients in children's cough due to upper respiratory tract infections (URTI) such as the common cold. The hypothesis is that protecting the throat is very useful in decreasing cough severity, both day and night, without needing to subdue such an important reflex as cough, and without only acting on mucous fluidification, especially in children where sedation and excessive fluidification is dangerous. The research hypothesis is that the protective (Grintuss) Syrup relieves cough (frequency, intensity, degree of disturbance due to nocturnal cough, and improves the quality of sleep of the child) as much as or more than the carbocysteine syrup usually used to treat children (Syr Mucolit).
详细描述
Cough is a life saving reflex, therefore it is important, especially in pediatrics, to calm cough spells without sedating the reflex. Mucolytic agents have been shown to be helpful but side effects have been reported and use has been prohibited under 2 years of age. Therefore, a completely safe and effective cough remedy has not been officially reported yet in a randomised trial. Looking into other mechanisms for cough management such as protection of irritated pharynx mucosa from post nasal drip or other irritating substances is theoretically sound and shows practical interesting results.
A parallel comparison of efficacy and tolerability between such protective mechanism (acting through a barrier and radical scavenging action) due to natural substances (honey, plantago lanceolata, grindelia robusta and helichrysum italicum) and a mucolytic substance has not been done so far, in young children, especially in a time frame of 4 days. The intent of this study is to use the protective syrup versus carbocysteine in children with moderate to severe night and daily cough, measured with a validated parent questionnaire. The invasiveness of cough is followed immediately after one night administration of the study products and daily for four days.
A similar effectiveness of the protective cough syrup as compared to carbocisteine is considered very interesting due to the mechanism of the remedy.

结局指标
主要结局
Change in Night Cough Score on First Night of Treatment (From N0 to N1)
时间窗: 1 night from before enrollment (N0) to first night after treatment (N1)
Night cough is most bothersome to the child and family. Cough was measured with a validated questionnaire which asks parents to rate 5 aspects of night cough: frequency, severity, bothersomeness, child sleep and parent sleep according to a 7 point Likert scale, from 0 (not at all) to 6 (extremely). Lower scores indicate a better condition. The morning after the first night of treatment (N1) the parents rated the passed night by scoring from 0-6 each of the 5 aspects of night cough. The sum of scores for all 5 aspects gives the combined night cough score. This score, ranging between 0-30, was subtracted from the sum of all aspects, also ranging between 0-30, form the basal night cough score of the night before enrollment (N0). This change is recorded as "change in combined night cough score" and it refers to the change from N0 to N1. Negative values of the change indicate an improvement in the condition of the patient.
次要结局
- Change in Day Cough Score at End of Study (From D0 to D4)(4 nights (onset of trial Night 1 to Night 4) and 3 days)
- Change in Night Cough Score at End of Study (From N0 to N4)(4 nights (onset of trial Night 1 to Night 4) and 3 days)
