Mechanism of action

Budesonide acts as a selective glucocorticoid receptor agonist that decreases airway inflammation by inhibiting the release of inflammatory cytokines, chemokines, and adhesion molecules. When delivered as an inhalation suspension, it deposits directly in the lungs, providing local anti-inflammatory effects with minimal systemic absorption. This reduces airway hyperresponsiveness and mucus production in asthma and other obstructive airway diseases.
