Introduction
Nitroglycerin aerosol generally has no effect on asthma. Asthma is an airway disease primarily caused by genetic and allergic factors. If immediate family members have asthma, the individual's risk of developing the condition is higher than that of the general population. Additionally, individuals with an allergic constitution may experience hypersensitivity reactions upon exposure to allergens such as pollen or paint.
Nitroglycerin aerosol generally has no effect on asthma. The detailed analysis is as follows:
Asthma is an airway disease primarily caused by genetic factors and allergies. If immediate family members have asthma, the individual's risk of developing the condition is higher than average. Additionally, individuals with allergic predispositions may experience hypersensitivity reactions when exposed to allergens such as pollen or paint fumes, which can trigger asthma attacks. During an attack, the airways become irritated by external stimuli, leading to frequent bronchoconstriction, increased airway secretions, changes in vascular permeability, and local mucosal edema, all of which impair normal breathing. Nitroglycerin aerosol works by relaxing blood vessels, reducing myocardial oxygen consumption, and thereby decreasing cardiac workload; however, it does not affect the trachea or bronchi. Therefore, nitroglycerin aerosol is ineffective for treating asthma. For patients diagnosed with asthma, medications such as montelukast sodium tablets or budesonide/formoterol inhalation powder should be used under a physician’s guidance.
In daily life, individuals should avoid environments with excessive dust and regularly clean personal items such as bed sheets and pillowcases.
