WebbThe mode of action of intranasal corticosteroids (INCS) is complex. It is not known whether INCS penetrate the nasal mucosa or act on target cells; however, their low systemic activity supports the concept of local action on nasal mucosa. WebbBronchodilators that are inhaled are a family of drugs that are used to treat a variety of respiratory disorders, including asthma and chronic obstructive pulmonary disease (COPD) (COPD). They function by easing the tension in the muscles that line the airways, which in turn makes breathing simpler. Short-acting beta-agonists (SABA) and short ...
