Abstract
Asthma is associated with autonomic nervous imbalance: an increased bronchial sensitivity to cholinergic constrictors and possibly a decreased sensitivity to β2‐adrenergic dilators have been reported in this disease. Also, non‐adrenergic and non‐cholinergic (NANC) mediators have a small regulatory effect on airway function. These mediators contribute to the pathogenesis of asthma not only by regulating smooth muscle tone in the airways but also by affecting pulmonary blood flow, endothelial permeability and airway secretions. In many studies increased parasympathetic responsiveness has been associated with clinical asthma or the worsening of asthma in adults. However, most of the studies in children have not found association between autonomic dysfunction and asthma. Therefore, the autonomic dysfunction in asthma may be related to more advanced disease or long‐term asthma medication in adults. This article briefly reviews the relationships between airway inflammation, β2‐agonist, anticholinergic and glucocorticoid medication as well as autonomic nervous function in asthma.Keywords
