    Abstract:
    BACKGROUND: The application of alcohol-containing medicinal products to children has been a subject of discussion for many years. A safety threshold of 0.125‰ blood alcohol concentration following the administration of a single dose has been recommended by the European Medicines Agency.The aim of this clinical study was to prove the safety of administering a fixed combination of thyme herb and primrose root fluid extract (Bronchicum(®) Elixir) containing 4.9% ethanol. METHODS: The herbal drug was administered for a period of 7-9 days to 16 children (ages 1-12 years) suffering from acute bronchitis for ≤ 48 h. After 3-5 days, a blood sample was taken 45 min (children ≥ 5 years: also 0 and 90 min) after application of the drug. The efficacy was assessed using the Bronchitis Severity Score. Global efficacy and tolerability were rated by the investigator and patients. RESULTS: All measured blood ethanol concentrations were below the threshold (mean value after 45 min: 0.0029 ± 0.0057‰ and after 90 min: 0.0051 ± 0.0078‰). The Bronchitis Severity Score decreased from 6.6 ± 1.0 to 0.9 ± 1.6 points. Global efficacy was assessed as "very good" and "good" in 60% (investigator) and 80% (patients) of cases. Global tolerability was rated as "very good" and "good" in more than 90% of cases. CONCLUSION: In conclusion, oral administration of the drug containing 4.9% ethanol to children (age 1-12 years) demonstrated a favourable risk/benefit ratio of the drug.
