Chronic bronchitis can be treated with levofloxacin, dextromethorphan, ambroxol hydrochloride, aminophylline and other drugs. Antibacterial and anti-inflammatory: Antibiotics are available for antibacterial and anti-inflammatory. In general, oral antibiotics are enough, and intravenous antibiotics are needed when the condition is serious. Commonly used drugs are levofloxacin, amoxicillin and cefuroxime. Take antibiotics according to the doctor's advice and don't stop taking them casually, so as not to cause bacterial resistance and affect the treatment effect. Cough-relieving and phlegm-resolving: Phlegm accumulates in patients with chronic bronchitis, and various harmful substances stimulate bronchi, leading to cough and expectoration. Dextromethorphan can be used to relieve cough in patients with cough but less phlegm. Dextromethorphan can relieve cough by inhibiting the cough center of the brain.

1. If there is too much phlegm, you can also use ambroxol hydrochloride, bromhexine and other expectorants to clear the sputum in the bronchus. Relieve asthma: Chronic bronchitis fills the bronchus with sputum and bacteria, which makes the bronchus swell, and the resistance of gas passing through the bronchus increases, and patients will have symptoms of wheezing and shortness of breath. Dilating bronchi can make breathing smooth and relieve symptoms.

2. Commonly used drugs to dilate bronchi include theophylline drugs such as aminophylline and theophylline controlled release agents, and β2 receptor agonists such as salbutamol. Cough is a typical symptom of chronic bronchitis, mainly in the morning, and there may be bouts of cough during sleep. If cough symptoms are not taken seriously and treated, it can develop into chronic bronchitis.
