Airway hyperresponsiveness is a premature and overpowering response of the airways to various physical and chemical factors stimuli, and patients usually react with irritating cough and wheezing symptoms as a result, which are commonly seen clinically in bronchial asthma and post-cold cough. The following methods of relief are available: 1. If the cough is caused by respiratory infection bacteria or viruses, active anti-infective treatment should be given to relieve airway sensitivity. 2. The most commonly used is glucocorticoid therapy, clinically using nebulized inhalation and sprays, using glucocorticoids such as budesonide aerosol or suspension, fluticasone aerosol, and if necessary, adding bronchodilators such as powdered Symbicort, sulforaphane, etc. Inhalation agents are also commonly used clinically to assist in the treatment of leukotriene modulators such as montelukast sodium, and occasionally with compound methocarbamol capsules.4. Relief of airway hyperresponsiveness should also try to avoid exposure to irritants to reduce their sensitivity.
