What oral medication to take for chronic inflammation of the lungs depends on what the causative agent of the infection is. If a patient presents with chronic inflammation of the lungs, he or she needs to improve blood work, C-reactive protein, calcitoninogen, sputum culture, mycoplasma antibodies, and other related tests. If the patient presents with elevated leukocytes, C-reactive protein, and calcitoninogen, the diagnosis of clinical bacterial infection is clear and requires treatment with antibiotics, such as cefixime, amoxicillin, azithromycin, and levofloxacin. If the patient’s mycoplasma antibodies appear quadruple elevated in the recent past, clinical consideration is given to mycoplasma infection, and macrolide azithromycin and erythromycin, or quinolone levofloxacin and moxifloxacin can be used. At the same time, symptomatic treatment is given, for example, coughing medication can be used when coughing affects rest and sleep, and expectorant medication can be used when there is phlegm that cannot be coughed out.
