There are many causes of cough, different drugs used, and a wide variety of medications, which must be used under the guidance of a doctor. Specific medications are as follows: 1. For mild coughs, no medications can be used, but when the cough is more intense and affects daily life and work, cough suppressants can be used. For acute and subacute coughs, first-generation antihistamines such as enalapril maleate can be used; 4. For coughs combined with colds, non-steroidal anti-inflammatory drugs can also be used; 5. For asthmatic coughs caused by bronchitis and patients with chronic obstructive pulmonary disease, the bronchodilators salbutamol and anticholinesterase inhibitors can be inhaled; 6. For asthma or patients with chronic obstructive pulmonary disease caused by allergic factors, oral glucocorticoids or inhalation preparations such as budesonide powder inhaler can be used, which is the same as bronchodilators and also has a significant effect on cough relief.
