Mechanism of action

Budesonide is a corticosteroid that suppresses inflammatory responses in the airways by binding to glucocorticoid receptors, reducing mucus production and airway edema. Formoterol is a long-acting beta-2 agonist that binds to beta-2 adrenergic receptors on bronchial smooth muscle, causing relaxation and bronchodilation. Together, they provide both anti-inflammatory and bronchodilatory effects for sustained asthma and COPD control.
