Patients with chronic bronchitis need to be given cough relieving, expectorant and symptomatic treatment first, such as oral ambroxol hydrochloride dispersible tablets, San'ao tablets and other drugs. Secondly, patients with chronic bronchitis often need to inhale long-term bronchodilators for treatment, such as tiotropium bromide and other drugs. In addition, patients with chronic bronchitis may also need to inhale long-term bronchodilators and glucocorticoids for treatment. If patients with chronic bronchitis are in a serious condition and have repeated acute attacks, it is necessary to consider inhale glucocorticoid on the basis of long-term bronchodilators. This treatment helps to reduce the acute attack of chronic bronchitis.
