How respiratory diseases are treated depends mainly on the cause of the disease and the accompanying clinical symptoms. There are relatively more diseases of the respiratory system in general, the most common being inflammatory reactions of the respiratory tract, such as bronchitis and pneumonia, which can be treated with anti-inflammatory drugs, and bacterial infections can be treated with antibiotics such as penicillin, amoxicillin, cefoperazone, levofloxacin and other drugs. For bronchial asthma you can choose bronchodilator drugs, as well as anti-allergic and anti-inflammatory drugs, such as nebulizer inhalation treatment with budesonide nebulizer, and salbutamol nebulizer, terbutaline nebulizer, etc. For diseases with idiopathic diffuse interstitial lung fibrosis, glucocorticoids such as dexamethasone, methylprednisolone, prednisone, etc., and combined immunosuppressive agents such as cyclophosphamide, etc., are generally available.
