Excessive sputum in the lungs needs to be clarified as to the cause of the excessive sputum and targeted treatment. Common diseases with excessive sputum in the lungs include tuberculosis, acute pneumonia, acute bronchitis, etc., which can be treated with anti-tuberculosis mycobacteria drugs, anti-infective, cough and phlegm medications. 1. Tuberculosis: Diagnosis can be confirmed by imaging and tuberculin test, and the treatment is based on early, regular, whole course, appropriate amount and combined treatment. Anti-tuberculosis drugs (e.g. isoniazid, rifampicin, etc.) are often used in conjunction with sputum-cleansing drugs (oral aminoglutethimide, bromhexine, etc.). 2. Acute pneumonia: acute onset, rapid development, part of the lungs can be heard wet rales, the principle of treatment is symptomatic treatment and antibiotic (such as cefazolin, cefaclor, amoxicillin, etc.) treatment. 3. Acute bronchitis: mainly due to microbial infection, physical and chemical factors (cold air, dust, irritating gases), allergic reactions, generally less severe systemic symptoms, but may be accompanied by fever, the principle of treatment is symptomatic treatment, such as anti-infective (such as cefazolin, cefaclor, etc.), and glucocorticosteroid inhalation therapy (such as budesonide, etc.) when necessary. If there is a lot of sputum in the lungs, there may also be other reasons, please consult a doctor in time, with the help of the doctor to clarify the cause of the disease, as soon as possible for standardized treatment. The above drugs need to be standardized and rationally applied under the guidance of professional physicians and pharmacists.
