Budesonide + Salmeterol + Montelukast

National Heart, Lung, and Blood Institute (NHLBI) · FDA-approved active Small molecule

This combination reduces airway inflammation via corticosteroid action, dilates airways through beta-2 agonist stimulation, and blocks leukotriene-mediated inflammatory pathways.

This combination reduces airway inflammation via corticosteroid action, dilates airways through beta-2 agonist stimulation, and blocks leukotriene-mediated inflammatory pathways. Used for Persistent asthma in patients not adequately controlled on inhaled corticosteroid and long-acting beta-2 agonist alone, Asthma with allergic or exercise-induced components.

Mechanism of action

Budesonide is an inhaled corticosteroid that suppresses inflammatory cytokines and immune cell recruitment in the airways. Salmeterol is a long-acting beta-2 agonist that relaxes bronchial smooth muscle and provides sustained bronchodilation. Montelukast is a cysteinyl leukotriene receptor antagonist that blocks inflammatory mediators involved in asthma pathogenesis, providing complementary anti-inflammatory and bronchodilatory effects.
