What this trial studies

This study evaluates the efficacy and safety of dry powder Ivy Extract (Syrup Prospan) compared to N-acetylcysteine (NAC) in patients with Chronic Obstructive Pulmonary Disease (COPD). It is a randomized, open-label interventional study where participants will be assigned to receive either Syrup Prospan or NAC for 30 days. The study will assess cough symptoms, health-related quality of life, and lung function before and after treatment. Participants will also provide feedback on their satisfaction with the treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 40 and above with stable COPD and documented lung function impairment.

Not a fit: Patients with other chronic lung diseases or those who are pregnant or nursing may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide an effective alternative treatment for managing COPD exacerbations.

How similar studies have performed: Previous studies have shown positive outcomes with mucolytic treatments in COPD, suggesting potential for success in this approach.
