Clinical Trial of the Efficacy and Safety of Raphamin in the Treatment of Acute Bronchitis in Adult Patients

The goal of this clinical trial is to learn if Raphamin works to treat acute bronchitis in adults. It will also learn about the efficacy and the safety of Raphamin. The main questions it aims to answer are: Will treatment with Rafamine contribute to a faster resolution of acute bronchitis symptoms, reduce the severity of the disease, and prevent the development of complications requiring antibacterial therapy compared to placebo therapy? Investigators will compare Raphamin to a placebo (a look-alike substance that contains no drug) to see if Raphamin works to treat acute bronchitis. Participants will: Take Raphamin or a placebo for 5 days. On the first day of treatment 8 tablets of Raphamin or a placebo should be taken using the following regimen: 1 tablet every 30 minutes for the first 2 hours (5 tablets in total for 2 hours), then 1 more tablet 3 times at equal intervals during the same day. On day 2 and onwards, 1 tablet should be taken 3 times a day. Face-to-face visits are planned in the trial: Visit 1 (Day 1), Visit 2 (Day 4±1), Visit 3 (Day 7±1), and a phone Visit 4 (day 14±1). The study uses an electronic patient diary (EPD) in which symptoms of acute bronchitis (cough, sputum, chest pain during coughing) are assessed daily.
