The drugs used to treat asthma can be roughly divided into the following categories. (1) Glucocorticoids (commonly known as hormones): glucocorticoids are the first choice for asthma treatment, usually based on inhaled hormones, with more side effects from intravenous use, and are generally used during severe asthma attacks. Representative inhalers include beclomethasone dipropionate, budesonide, etc.; (2) bronchodilators: β2 agonists can rapidly relieve airway narrowing and are the drugs of choice for controlling asthma attacks. Short-acting β2 agonists have a duration of action of 4-6 hours, and the representative drugs are salbutamol and tert-butamol; long-acting β2 agonists have a duration of action of 8-12 hours, and the representative drugs are Mebeverine and Schizophrenia. (3) anticholinergic drugs: cholinergic receptor antagonist, combined with β2 agonist inhalation has a synergistic effect, especially for patients with nocturnal asthma and sputum; (4) theophylline drugs: theophylline extended-release agents such as Shuflumet can act for up to 12 hours, and can be used for chronic and nocturnal patients; (5) theophylline drugs: theophylline extended-release agents such as Shuflumet can act for up to 12 hours. (5) mast cell membrane stabilizers: such as sodium cromoglycate, which mainly inhibits the release of histamine, leukotrienes and prostaglandins from mast cells and reduces airway inflammation; (6) other drugs such as immunosuppressants, which can be used as appropriate depending on the condition.
