Inhaled Reduced Glutathione

Serafino A. Marsico · Phase 3 active Small molecule

Inhaled reduced glutathione acts as an antioxidant and mucolytic agent that replenishes intracellular glutathione levels and reduces oxidative stress in the lungs.

Inhaled reduced glutathione acts as an antioxidant and mucolytic agent that replenishes intracellular glutathione levels and reduces oxidative stress in the lungs. Used for Cystic fibrosis (likely primary indication), Idiopathic pulmonary fibrosis or other chronic lung diseases with oxidative stress.

Mechanism of action

Glutathione is a tripeptide antioxidant that plays a critical role in protecting cells from oxidative damage and maintaining redox balance. When inhaled directly, reduced glutathione can increase local glutathione concentrations in respiratory epithelial cells and airway secretions, enhancing antioxidant defenses and potentially improving mucociliary clearance. This mechanism may be particularly beneficial in conditions characterized by oxidative stress and impaired lung function.
