Although asthma is not curable, advancements have enabled an evolution in pharmacologic interventions, which form the mainstay of asthma management because they reduce airway inflammation and airway hyperreactivity. (1) These medications can be categorized as controller medications, which reduce inflammation and exacerbation risk, and reliever medications, which alleviate bronchospasm and acute symptoms.

In the study of Pincus-Knackstedt et al., when stress to the mother during the gestational stage and an OVA sensitization to the offspring were observed, an inflammation of atopic characteristics was observed, specifically in the submucosa area of the airway, and muscle hyperreactivity in the offspring of prenatally stressed mothers.
One intriguing mechanism that has been proposed is that pressor hyperreactivity is a manifestation of a widespread basic membrane transport disorder that disrupts cellular cation homeostasis.
