There are no specialized anti-inflammatory drugs for lung nodules until the cause is clearly identified. There are many causes of lung nodule formation, such as tuberculosis, pulmonary nodular disease, pulmonary fungal disease, and lung cancer. The treatments for different causes are different. 1. Tuberculosis: The treatment of pulmonary nodules caused by tuberculosis should be based on anti-tuberculosis treatment. At present, the classic first-line anti-tuberculosis drugs include rifampicin, isoniazid, pyrazinamide, ethambutol and streptomycin. Tuberculosis is an infectious disease that can be cured, and should be standardized and treated as early as possible by professional doctors. 2. Pulmonary nodular disease: asymptomatic and normal or slightly abnormal lung function can be without treatment, if there are obvious pulmonary or extrapulmonary symptoms need to use glucocorticosteroid treatment according to the actual situation. 3. Pulmonary fungal disease: the treatment of pulmonary nodules caused by pulmonary fungal disease is based on antifungal treatment, and voriconazole, fluconazole, itraconazole, amphotericin B and other drugs can be used to carry out antifungal treatment. However, there are different types of fungi, and the preferred drugs for different fungi are different, so antifungal treatment should be carried out by specialized doctors according to the actual situation. 4. Lung cancer: Lung cancer may also have the manifestation of lung nodules. At present, the treatments for lung cancer include radiotherapy, chemotherapy, surgery and interventional therapy.
