Studying Inhaled Nitroglycerin to Improve Breathing in Adults with Severe COPD and Lung Blood Vessel High Pressure

What this Trial Is About

Researchers are evaluating the effects of inhaled nitroglycerin on improving respiratory function in patients with late-stage Chronic Obstructive Pulmonary Disease COPD, especially those experiencing respiratory failure and pulmonary hypertension. The study aims to investigate how this treatment may help by dilating pulmonary arteries to reduce ventilationperfusion mismatch and improve antibiotic delivery to the lungs. This trial is sponsored by Beni-Suef University and includes patients admitted to adult intensive care units. Participants will be randomly assigned to one of two groups. One group will receive the standard treatment for COPD exacerbation, including antibiotics, corticosteroids, and bronchodilators. The other group will receive inhaled nitroglycerin in addition to the standard treatment. The study is designed as a phase 2 and phase 3 trial, with no blinding, and will monitor the effects over several days. During the study, participants will be closely monitored for changes in pulmonary function five days after starting the inhaled nitroglycerin. Researchers will also track the number of days on mechanical ventilation, the dose of vasopressor therapy, reduction in white blood cell count, and mortality rate up to ten days after treatment begins. The study aims to understand the treatments impact on respiratory failure in COPD patients and will continue until December 2025.
