What medication for bronchitis is most effective for relieving cough?

There is no such thing as "the best cough medicine for bronchitis," but medications that are relatively effective for relieving cough in bronchitis include dextromethorphan, pentopverine, ambroxol, acetylcysteine, and salbutamol. The choice should be based on the type of cough and the patient's condition to avoid blind medication use. If cough persists for more than one week or is accompanied by fever, hemoptysis (coughing up blood), or difficulty breathing, prompt medical attention is recommended.

1. Dextromethorphan: A centrally acting antitussive that suppresses the cough center in the brain. It is suitable for bronchitis patients with dry cough or minimal sticky sputum. It has a strong cough-suppressing effect without depressing respiration. Dosage must be strictly followed to prevent overdose.

2. Pentopverine: Acts both centrally and peripherally to suppress cough and relieve spasms of respiratory smooth muscles. It is effective for various types of cough caused by bronchitis, including dry cough and mild productive cough, with relatively mild side effects.

3. Ambroxol: A mucolytic agent that thins and loosens thick mucus, promoting its expulsion. It is suitable for bronchitis patients with excessive, viscous, and difficult-to-expectorate sputum. By reducing mucus irritation to the airways, it indirectly alleviates cough symptoms.

4. Acetylcysteine: Reduces sputum viscosity by breaking down mucoproteins in mucus. It is indicated for bronchitis patients with thick, purulent mucus causing airway obstruction. It rapidly improves difficulty in expectoration and works better when used in combination with antitussive medications.

5. Salbutamol: A bronchodilator that relieves airway spasms. It is suitable for bronchitis patients with wheezing or chest tightness. It reduces cough caused by airway narrowing. Note that it may cause increased heart rate after use.

During treatment, maintain good indoor ventilation and humidity, avoid exposure to irritants such as smoke and dust, drink plenty of warm water to soothe the throat, follow a light and easily digestible diet while avoiding spicy and greasy foods, maintain regular作息 (daily routine), avoid overexertion, and ensure adequate rest to support repair of the respiratory mucosa.
