The correct name for variant cough asthma is cough variant asthma, and the principles of treatment are similar to those of typical asthma, with therapeutic agents including inhaled low-dose glucocorticosteroids (e.g. budesonide) and bronchodilators (e.g. salbutamol). The treatment should be tailored to the stage of the disease. 1. Mild acute exacerbation: Inhalation of bronchodilators such as salbutamol can be used, usually within a few minutes, as well as salbutamol. 2. Moderate acute exacerbation: Inhaled bronchodilators only partially improve the symptoms, so it is often necessary to use a combination of inhaled glucocorticoids (beclomethasone propionate or budesonide aerosol). People with moderate acute asthma attacks often have nocturnal asthma attacks and symptom exacerbation, and often require medications such as long-acting extended-release theophylline to effectively prevent nocturnal asthma attacks. 3. Severe acute exacerbations: bronchodilators and glucocorticoids may not be effective in this case, and hospitalization is often required for emergency treatment. If the diagnosis of cough variant asthma, should be promptly to the hospital standardized treatment, combined with infection need to choose antibiotics. The above medications should be used under the guidance of a doctor, avoid self-medication.
