Nebulized inhalation drugs for asthma mainly include the following: 1, glucocorticoids: including budesonide, beclomethasone, pramipexole, etc., which are usually used in patients with acute severe asthma attacks; 2, β2 agonists: according to the rapid and slow onset of action and the length of action, they can be divided into long-acting β2 agonists and short-acting β2 agonists. Long-acting β2 agonists include salmeterol, formoterol, etc., and short-acting β2 agonists, including salbutamol, etc. During acute asthma attacks, patients are recommended to inhale short-acting β2 agonists. And in the period of asthma remission, patients are recommended to use glucocorticoids combined with long-acting β2 agonists by inhalation; 3. Anticholinergic drugs: including ipratropium bromide, etc. In addition to nebulized inhalation drugs, patients can take oral theophylline tablets, theophylline extended-release tablets or intravenous doxorubicin, aminophylline and other theophylline drugs, and also use leukotriene modulators and other antihistamines to treat asthma. If asthma is triggered by inflammation of the respiratory tract, aggressive anti-infection treatment is also needed to control the asthma trigger.
