Respiratory Tract Infection Viral
Conditions
Brief summary
Aim of this study is to investigate efficacy and safety of Echinaforce Junior Tablets (250mg) in comparison with Vitamin C tablets in the prevention of acute viral respiratory tract infections.
Detailed description
200 children aged 4-12 years are recruited by pediatricians and general practitioners and are allocated to preventive treatment with either Echinaforce Junior tablets or Vitamin C. Children take 3 x 1 tablet per day over a period of 2 months followed by 1 week treatment break and an intermediate study visit (V2). Thereafter children continue with preventive Treatment for another 2 months, followed by exclusion visit (V3). Parents are required to contact a study coordinator at the occurrence of acute respiratory Symptoms to initiate symptom recording via internet-based e-diary. On day 1 - 3 of episode parents will sample nasal secretion, which will be analysed for common respiratory agents.

| Incidence of respiratory tract infections (viral RTIs) | 4 months prevention | Occurrence of colds and flu episodes |
| Acceptance in the view of the parents | 4 months prevention | Parents will judge the acceptance after 4 months (would you use the medicament again?) |
| Occurrence of adverse drug reactions | 4 months prevention | Occurrence of adverse drug reactions will be analysed by descriptive methods |

| Occurrence of adverse events | 4 months prevention | Occurrence of adverse events will be analysed by descriptive methods |
| Efficacy in the view of the parents/children | 4 months prevention | Parents/children will give their subjective impression of efficacy by ratings bad, moderate, good or very good. |
| accompanying virus analytics | 4 months prevention | nasal samples will be taken at occurrence of cold Symptoms and will be analysed for the presence of respiratory viruses |
| effects on the endogenous defense | 4 months prevention | Question will be asked do you think that the prevention had the follwing effects on the endogenous defense in your child? (unchanged; improved; significantly improved) |
| Concomitant treatment and therapies | 4 months prevention | Concomitant treatment and therapies will be coded using medical dictionary for Regulatory Agencies and will be analysed descriptively for the two treatment groups |
