Chronic cough is treated differently according to the cause of the disease, and only with the right medication can good results be achieved. Whether or not it can be completely cured varies from person to person and is not conclusive. For example, non-asthmatic eosinophilic bronchitis, cough variant asthma, gastroesophageal reflux disease (GERD), different treatments should be given according to the cause of the disease. 1. Non-asthmatic eosinophilic bronchitis: manifested by chronic irritating cough, generally normal pulmonary ventilation, airway hyperresponsiveness test is negative, but the treatment effect is good after using glucocorticoid. It is usually treated with inhaled glucocorticoids, such as beclomethasone propionate inhalation aerosol. Most of them can be well controlled after standardized treatment. 2. Cough variant asthma: it is a special type of asthma with cough as the only manifestation, which generally cannot be completely cured, but can be significantly improved by giving bronchodilator and glucocorticoid treatment. Inhalation of small doses of glucocorticoids plus beta agonists can be used, such as budesonide formoterol powder inhaler. 3. Gastroesophageal Reflux Disease (GERD): Because of acid reflux with acid reflux, heartburn, cough and other symptoms, the treatment is based on antacids such as omeprazole and gastric stimulants such as mosapride, etc., which can be cured after standardized treatment. However, if the cough is caused by chronic bronchitis and chronic obstructive pulmonary disease, it cannot be completely cured, and symptomatic treatment can be used to reduce acute exacerbation. There are many other causes of chronic cough, such as post-nasal drip syndrome, etc. Patients with the corresponding symptoms need to go to the hospital according to the different clinical symptoms to do the appropriate examination to find the cause of the targeted treatment, to avoid delaying the condition.
