The principles of treatment of acute pneumonia are mainly symptomatic and etiological treatment. Acute pneumonia is an inflammatory reaction in which the mucous membrane of the lung becomes congested, edematous and exuded inflammatory substances due to the decrease of the body’s resistance and the invasion of pathogens. For the cough and coughing sputum that appear, you can choose to use drugs to reduce sputum, such as taking tranylcypromine oral solution, tranylcypromine hydrochloride syrup, carboxymethylstilbestrol oral solution, granules to reduce phlegm and cough, and nourishing yin and clearing lung pill, etc. You can also use glucocorticoids, such as budesonide nebulizer and chymotrypsin nebulizer inhalation, to stop cough and reduce sputum for symptomatic treatment. Anti-pathogen treatment, such as anti-bacterial can choose to use penicillin, amoxicillin, cefoperazone, azithromycin, levofloxacin, etc.; anti-fungal can choose amphotericin B, ashwagandha, etc.; antiviral can choose to use interferon, ribavirin, oseltamivir, etc. If necessary, take the secretions of the respiratory tract for pathogen culture as well as drug sensitivity test to select highly sensitive anti-inflammatory drugs and adjust the treatment plan.
