The Performance and Safety of Petit Drill in the French Paediatric Population: a Post-market Clinical Follow-up Study.

Demulcent or soothing substance is the currently recommended option to alleviate throat irritation associated to cough and sore throat in children under 6 years. The intended benefit to the patient of Petit Drill is to calm throat irritation (sore throat) associated to dry cough in infants starting at 6 months of age and in children up to 6 years of age. This intended benefit sustained by the properties of the formula is recognized and promoted by the World Health Organization, health authorities and current textbooks to have a positive impact on patient management for the targeted population (infant / child).

This study aims at assessing the effectiveness of the syrup in real-life context, in children presenting throat irritation to support the conclusion of clinical evaluation report.

Pediatric patients are recruited by pharmacist in community settings, who briefly present the clinical investigation to the parent who purchases Petit Drill for his/her child.

The pharmacist provides to interested parent the study inform note and transfer the parent's name and contact information to the clinical investigation centre. The parent is contacted to take part to the remote inclusion visit with a site investigator, scheduled within the day of Petit Drill delivery. Once consent has been signed, the investigator verifies eligibility criteria, then collects baseline data.

Follow-up lasts as long as the child receives the syrup, but no longer than 3 days and 3 nights. The parent completes daily questionnaires and record syrup intake in a secure mobile application for patient reported outcomes.
