Comparison of a Protective Cough Syrup Against Placebo on Night Cough in Children 1-5 Years Coughing Since 1- 2 Days Due to Common Cold
Study Details
Study Description
Brief Summary
The intent of this study is to see how boys and girls aged 1-5 and coughing since 1-2 days due to common cold respond to a specific protective cough syrup taken before going to bed for one night, with respect to a similar but not specific syrup (placebo). The symptoms evaluated include especially cough frequency but also cough intensity, bother, and sleep quality of the child and parents.

Detailed Description
Cough is a life saving reflex, therefore it is important, especially in pediatrics, to calm cough spells without sedating the reflex. Looking into mechanisms for cough management different from mucolytics, or sedatives, 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 and thymus vulgaris) and placebo has been looked at specifically on the clinically critical population of children coughing since 1-2 days and not more, including very young children of one year old. The intent of this study is to use the protective syrup versus placebo in children with moderate to severe night and daily cough, measured with a validated parent questionnaire. Daily cough is assessed to better describe and select the general condition of the child however only night cough parameters due to treatment are assessed. The degree of disturbance of cough is followed immediately after one night administration on all night parameters, with special interest to frequency.
Assessment of effectiveness of the protective cough syrup as compared to placebo is considered very interesting due to the mechanism of the remedy. The study looks at the effect of the syrup/placebo on the first night in order to well focus the "first" effect of a treatment on the ascending phase of the illness, such as to reduce to a minimum any interference due to natural regression of the symptom due to illness progression.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Cough Syrup for adults and children CE Marked (authorized) medical device acting by protecting the oropharynx, in a non-pharmacological way, to reduce cough. It contains honey, plantago lanceolata, thymus vulgaris. Dosage form: syrup Dosage: 5 ml. Duration: one night |
Device: Cough Syrup for adults and children
The intervention product is a medical device in Europe due to its non-pharmacological mode of action, which makes the product compliant to the medical device definition. It is made of specific extracts of plants (plantago and thymus) which provide the product with protective characteristics of the oropharynx. These protective features enable the syrup to reduce the irritative cough promoting stimuli on the throat, which decrease urge to cough threshhold. In addition to these extract, honey completes the formula. The product does not contain any artificial component and no preservatives.

Placebo Comparator: Placebo The placebo intervention is a similar syrup of taste and colour, with general protective components and other necessary synthetic components which may have an influence on cough, without the specific natural protective components. Dosage form: syrup. Dosage: 5 ml. Duration: one night |
Device: Placebo
The placebo intervention is a syrup of same taste and colour without the natural protective components but with the necessary synthetic preservatives and other co-sweeteners to guarantee quality and safety. The placebo has, in fact, all the features of a cough syrup since true placebo syrup is not possible in cough. The lack of specific natural protective components is weighed against the presence of other necessary substances which may still have an effect on cough, but this effect is not envisaged to be a specific protective effect.

Outcome Measures
Primary Outcome Measures
- Night cough frequency score reduction [First and only night of treatment]
Night cough frequency is the most invasive element of distress to the child and family. The questionnaire rating night cough is filled in the morning following enrollment, relating to the passed night. The basal night score is the score of the night before enrollment.
Secondary Outcome Measures
- night cough intensity score reduction [First and only night of treatment]
All these other elements constitute cough invasiveness into the quality of life of child and parents
- night cough bothersomeness score reduction [First and only night of treatment]
All these other elements constitute cough invasiveness into the quality of life of child and parents
- reduction of influence of cough on child sleep score [First and only night of treatment]
All these other elements constitute cough invasiveness into the quality of life of child and parents
- reduction of influence of cough on parent sleep score [First and only night of treatment]
All these other elements constitute cough invasiveness into the quality of life of child and parents
- reduction of influence of cough on combined night score [First and only night of treatment]
All these other elements constitute cough invasiveness into the quality of life of child and parents
