Comparison of Efficacy and Tolerability of Two Cough Syrups in Cough Due to Cold 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).
