About

This is a randomized, open-label, single-center clinical trial evaluating the efficacy and safety of Azka Nasal and Throat for Children compared to the control drug Prospan Cough Syrup in children aged 4-6 years diagnosed with acute nasopharyngitis. Participants will be randomly assigned in a 1:1 ratio to receive either Azka Nasal and Throat or Prospan Cough Syrup for 7 days. The study aims to assess improvements in cough and phlegm conditions, as well as monitor adverse events associated with the interventions. Data will be collected over a 15-day period, including screening, treatment, and follow-up phases.

Full description

This clinical trial aims to compare the efficacy and safety of Azka Nasal and Throat for Children, a registered health supplement, with Prospan Cough Syrup, a commonly used control drug. The study targets children aged 4-6 years diagnosed with acute nasopharyngitis, presenting symptoms such as cough, nasal mucus, and throat phlegm.

Participants will be randomly assigned in a 1:1 ratio to one of two arms:

Azka Nasal and Throat for Children: Administered orally at 7.5 ml per dose, three times daily, 30 minutes before meals, for 7 days.

Prospan Cough Syrup: Administered orally at 2.5 ml per dose, three times daily, 30 minutes before meals, for 7 days.

The study spans 15 days for each participant, consisting of three phases:

Screening Phase (1 day): Eligibility determined based on inclusion and exclusion criteria.

Treatment Phase (7 days): Daily administration of the assigned intervention. Follow-Up Phase (7 days): Monitoring of post-treatment outcomes. Primary outcomes include changes in cough and phlegm conditions assessed on Days 4 and 8, using the PCC scale, cough frequency, and duration of each episode, as well as the assessment of nasal and throat mucus. Secondary outcomes include the evaluation of adverse events for both interventions.

Data will be analyzed using SPSS Statistics 23.0 software to determine efficacy and safety. Descriptive statistics, t-tests, and Mann-Whitney tests will be applied based on data distribution. A significance level of p < 0.05 will be used.

This study seeks to provide valuable insights into the effectiveness of Azka Nasal and Throat for Children in improving respiratory symptoms and its safety profile compared to an established control drug.
