Allergic asthma is categorized into acute exacerbation and chronic persistence, and is usually treated with medication, commonly used drugs include salbutamol, budesonide, etc., but there is no so-called “optimal treatment”. 1. Acute exacerbation period: the principle of treatment in this period is to release bronchospasm and relieve symptoms, commonly used drugs include short-acting β₂ agonists, such as salbutamol, terbutaline, and so on. 2. Chronic persistence: Inhaled glucocorticoids such as budesonide aerosol can be used, and long-acting β₂ agonists such as salmeterol can be used to diastole the bronchial smooth muscle, or compound preparations can be used. Allergic asthma patients usually have to avoid contact with allergens, understand the relevant knowledge of the disease, immediately consult a doctor for treatment after the appearance of uncomfortable symptoms, and strictly comply with the doctor’s instructions for medication.
