What this trial studies

This study investigates the effects of nebulized nitroglycerin on respiratory function in patients with late-stage Chronic Obstructive Pulmonary Disease (COPD). The approach focuses on the vasodilation of pulmonary arteries and arterioles, which can alleviate ventilation/perfusion mismatching that exacerbates COPD symptoms. Additionally, the study aims to enhance antibiotic delivery to the alveoli, potentially improving infection control in these patients. It is designed as an interventional study, encompassing both Phase 2 and Phase 3 evaluations.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with COPD exacerbation and evidence of pulmonary hypertension.

Not a fit: Patients with profound left ventricular failure, pregnant women, or those with hypersensitivity to nitroglycerin may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve respiratory function and quality of life for patients with severe COPD.

How similar studies have performed: While the use of inhaled nitroglycerin is a novel approach in this context, similar studies have shown promise in improving respiratory outcomes in other conditions.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Adult patient's ≥ 18 years old COPD exacerbation with respiratory failure and Echo evidenced presence of pulmonary hypertension (defined as mean pulmonary artery pressure \> 20 mmHg)

Exclusion Criteria:

* Profound left ventricular failure, as the decrease in pulmonary vascular resistance results in an increase in left ventricular preload. This may worsen cardiogenic pulmonary edema.
* Pregnant female patients
* Patient with hypersensitivity to nitroglycerin
