Introduction
Treatment options for cough variant asthma include bronchodilators and inhaled corticosteroids. Currently, the bronchodilators most commonly used in clinical practice are short-acting β₂-adrenergic agonists; theophylline must be used only under physician supervision. For patients with intermittent asthma exacerbations, medications may be used as needed. The most commonly used corticosteroid is [incomplete sentence—original text ends abruptly].
Cough-variant asthma (CVA) is a distinct subtype of asthma often triggered by an unresolved common cold. Its primary symptom is chronic cough, typically presenting as an irritative cough. Due to its persistent and difficult-to-treat nature, CVA significantly impacts patients’ work, studies, and daily life. So, how is cough-variant asthma treated?
Treatment of Cough-Variant Asthma
Treatment options for cough-variant asthma include bronchodilators and inhaled corticosteroids. Clinically used bronchodilators primarily consist of short-acting beta-2 adrenergic agonists; theophylline must be administered strictly under medical supervision. For patients experiencing intermittent asthma episodes, these medications may be used as needed. The most commonly prescribed inhaled corticosteroids are fluticasone propionate and budesonide, which effectively suppress disease symptoms. However, they should also be used only under physician guidance to avoid potential systemic side effects.
The main underlying cause of cough-variant asthma is a sustained decline in immune function, rendering individuals more susceptible to certain allergens. Common triggers include pollen, cooking fumes, cold air, house dust mites, household dust, and high-protein foods—such as milk, soy milk, eggs, and seafood—as well as emotional stress and vigorous physical exercise. These factors can induce airway hyperresponsiveness, characterized primarily by airway mucosal congestion and edema, along with partial contraction of bronchial smooth muscle. Consequently, patients experience persistent, paroxysmal, irritative coughing—a hallmark feature of this unique form of bronchial asthma.
Patients are advised to consume nutrient-rich foods high in vitamins, especially fruits and vegetables, and to maintain adequate hydration by drinking plenty of water. We hope this information proves helpful.
