Chronic obstructive pneumonia, in case of acute exacerbation, requires control of intrapulmonary infection and can be treated symptomatically with antibiotic drugs, such as penicillins, cephalosporins, macrolides and quinolones. If oral medications are not effective, they can be given intravenously. If necessary, sputum culture and drug sensitivity test can be checked to select the most sensitive antibiotic drugs for symptomatic treatment. In severe cases, a combination of drugs or even glucocorticoid anti-inflammatory hormone can be used to improve the efficacy. It can be combined with expectorant drugs, such as bromhexine hydrochloride, amiloride hydrochloride, acetylcysteine, etc., which can improve the efficacy of antibiotics. Bambuterol oral solution can be taken orally, which can have the effect of diluting phlegm, and can promote the discharge of phlegm and improve the effect of antibiotics. It can be treated by proprietary Chinese medicine, such as acute syrup, honey-refined Chuanbei loquat paste, powerful loquat extract and other cough and phlegm-relieving drugs. If it is a stable period, you need to pay attention to weather changes, prevent cold and keep warm to avoid the symptoms of upper respiratory tract infection.
