The treatment of cough and asthma in children is divided into two parts. One is the treatment of causes, the other is symptomatic treatment. If the treatment of cough and asthma is caused by infection factors, anti infection treatment should be targeted. If children's cough and asthma are considered as allergic factors, they need to use anti allergic drugs. The second kind of symptomatic treatment mainly uses theophylline, anticholinergic drugs, β receptor agonists and other bronchodilators to relieve spasm. In addition, oral administration of leukotriene receptor antagonist and symptomatic treatment of atomization can also be added.
