What is the therapeutic action of a combination inhaler containing a long-acting beta2-agonist and a steroid?

Explanation:
These combination inhalers work by addressing both bronchoconstriction and airway inflammation. The long-acting beta2-agonist relaxes the smooth muscle of the airways, producing bronchodilation and easier breathing. The corticosteroid reduces airway inflammation by decreasing inflammatory cell activity and mediators, which lowers edema and mucus production over time. Together, they provide both immediate airway opening and ongoing anti-inflammatory control, making bronchodilation with reduced airway inflammation the best description of their therapeutic action. While the steroid component targets inflammation and the bronchodilator provides dilation, the most complete answer is that the combination delivers both effects.
