Cough variant asthma is one of the most common causes of chronic cough in children, with cough as the only or main manifestation without significant wheezing. It is usually treated with general therapy and medication. 1. General treatment: some patients can find the allergens or other non-specific stimuli that cause asthma attacks, so that the patient out of and long-term avoidance of exposure to these risk factors is the most effective way to prevent and treat asthma. 2. Medication: Asthma medications are categorized into controlling drugs and relieving drugs. Controlling drugs include inhaled glucocorticoids such as budesonide inhalation aerosol and beclomethasone propionate inhalation aerosol, leukotriene modulators such as montelukast, long-acting β₂ agonists such as salmeterol and formoterol, theophyllines such as aminophylline, and long-acting anticholinergic drugs such as tiotropium bromide. Relievers include short-acting β₂ agonists such as albuterol and terbutaline, inhaled anticholinergics such as ipratropium bromide aerosol, short-acting theophylline and glucocorticoids such as oral prednisone or prednisolone. The principles of treatment for cough variant asthma are the same as those for typical asthma. Inhaled low-dose ICS combined with long-acting β₂ agonists or leukotriene modulators, slow-release theophylline, and short-term oral low-dose hormone therapy may be chosen for most patients, if necessary. The course of therapy can then be shorter than in typical asthma. Serum IgE testing, etc., reduces the likelihood of asthma triggers by avoiding allergens. If cough variant asthma is present in children, it is recommended to seek medical attention and actively cooperate with treatment.
