Study of Rengalin Liquid for Treating Cough in Children Aged 6 Months to 3 Years During Flu and Acute Respiratory Virus Epidemics

What this Trial Is About

Researchers are evaluating the efficacy and safety of a liquid form of Rengalin for treating cough caused by acute viral upper respiratory tract infections in children aged 6 months to 3 years during the epidemic growth of influenza and ARVI. This randomized, double-blind, placebo-controlled trial compares Rengalin with a placebo to determine its effect on cough severity in young children. Participants will be randomly assigned to receive either 5 ml of Rengalin or a placebo orally three times a day for 7 days. The study includes initial screening and consent, followed by treatment and monitoring visits on days 1, 4, and 8, with a phone follow-up on day 14. On day 4, if needed, mucolytic ambroxol may be added while continuing the assigned study treatment. Parents will use an electronic diary to record cough severity twice daily throughout the study. During the study, researchers will assess symptoms, perform physical exams, and conduct laboratory tests including blood and urine analyses in at least half the participants. Safety and treatment adherence are closely monitored through visits and diaries. The main outcome is the percentage of patients responding to treatment by day 3, with secondary outcomes including changes in cough severity by day 7. The total study duration for participants is up to 14 days with ongoing observation.
