Official Title: A Double-blind, Placebo Controlled, Randomized Crossover Trial to Characterize the Mucolytic Effectiveness of Tacholiquine® in Chronic Bronchitis
Brief Summary: The purpose of this study is to evaluate the mucolytic activity of Tacholiquine® compared to saline (0.9%) in chronic bronchitis patients. Lung function parameters, biomarker profiles in sputum and serum, and clinical symptoms by standardized questionnaires [COPD activity index (CAT), Baseline Dyspnea Index (BDI) & Transition Dyspnea Index (TDI)and the St. George's Respiratory Questionnaire (SGRQ)] will be evaluated in response to Tacholiquine® vs. saline in chronic bronchitis patients.
