Abstract:
The aim of this study was to explore possible interactions between a glucocorticosteroid (budesonide) and a long-acting beta(2)-agonist (formoterol) on pro-inflammatory cytokine release. Primary bronchial epithelial cells (PBEC) were stimulated with organic dust and incubated with budesonide, formoterol, and the combination of both drugs. Interleukin (IL)-6 and -8 in the supernatant was assessed by enzyme-linked immunosorbent assay (ELISA). Formoterol increased the IL-6 release but did not influence the IL-8 release. Budesonide attenuated the IL-6 and IL-8 release, an inhibiting effect that was sustained, but not reinforced, by formoterol.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Antiasthma Drugs: β2-Adrenoceptor Agonists
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce relaxation in these...
Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
