The treatment of interstitial inflammation of both lungs can choose glucocorticoids, immunosuppressants, antifibrotic drugs and so on according to different situations. 1. Glucocorticoid: the etiology of interstitial pneumonia is still unclear, but for the presence of interstitial fibrosis caused by rheumatoid immune disease, glucocorticoid can be used to inhibit the inflammatory response of the lungs, and commonly used drugs are prednisone, methylprednisolone and so on. Glucocorticoids should be used in the process of attention to the dosage, to reduce the occurrence of side effects. 2. Immunosuppressants: For interstitial fibrosis caused by rheumatoid immune disease, immunosuppressants can be used to slow down the development of the disease, such as cyclophosphamide, azathioprine and so on. Immunosuppressants are often used in combination with glucocorticoids, and patients are prone to infections during the use of these drugs, so attention should be paid to monitoring. 3. Anti-fibrotic drugs: interstitial pneumonia often occurs in the lung idiopathic fibrosis, the use of anti-fibrotic drugs can delay the lower lung function, commonly used drugs such as pirfenidone, nidazepam. Antifibrotic drugs can effectively improve the survival of patients, but need to pay attention to the adverse drug reactions. Patients with interstitial inflammation of both lungs should choose individualized drug therapy suitable for them under the guidance of their doctors, and need to monitor all aspects of function during the process of medication, and seek medical attention in time if they feel unwell.
