Cough Clinical Trial
Official title:
Randomized, Single Blind, Multicenter Study to Evaluate the Efficacy and Tolerability of Syr. Grintuss Pediatric and Syr. Mucolit in Cough Due to Upper Respiratory Tract Infection in Children
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).
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.
