Cough Clinical Trial
Official title:
Multicenter Open-label Randomized Clinical Trial of the Efficacy and Safety of Levopront® Syrup 30 mg/5 ml in Comparison With Libexin® 100 mg Tablets in Patients With Dry Non-productive Cough Caused by Acute Upper Respiratory Infection
Primary objective: To assess the efficacy of Levopront® in comparison with Libexin® based on daytime cough resolution rate by Day 8. The daytime cough symptoms resolution corresponds to 0 or 1 points on the "Six-point daytime and nighttime cough assessment scale". Secondary objectives: Treatment effect assessment in terms of the following efficacy and safety parameters: - To assess the efficacy of Levopront® in comparison with Libexin® based on nighttime cough resolution rate by Day 8. - Daytime and nighttime cough symptoms resolution according to "Six-point daytime and nighttime cough assessment scale" by Day 4. - Change in severity and frequency of daytime and nighttime cough according to "Six-point daytime and nighttime cough assessment scale" on Day 4 and Day 8 from baseline on Day 1. - Cough intensity change according to the visual-analogue scale on Day 4 and Day 8 from baseline on Day 1. - Change of FEV1 on Day 8 from baseline values on Day 1. - Rate of Adverse events (AE) and Serious Adverse Events (SAE) of the various severity according to subjective complaints, laboratory test results, physical examination, vital signs and spirometry
This is a multicenter, open-label, randomized, clinical trial to assess the efficacy and safety of Levopront® syrup 30 mg/5 ml in comparison with Libexin® 100 mg tablets in patients suffering from dry non-productive cough caused by acute upper respiratory infection ;
