What is the most effective medication for cough caused by bronchitis?

The choice of medications for treating tracheitis-related cough should be based on the patient's specific condition, as the most effective treatment varies from person to person. Generally, commonly used medications include antitussives (e.g., dextromethorphan, pentoxifylline), expectorants (e.g., ambroxol hydrochloride, bromhexine), and anti-asthmatic drugs (e.g., salbutamol, aminophylline). These medications work by suppressing the cough reflex, thinning mucus secretions, and dilating the airways, respectively, thereby relieving cough symptoms. Specific medication selection and dosage should be determined by a physician according to individual patient conditions; self-medication should be avoided. Additionally, maintaining adequate hydration, avoiding exposure to irritants, and getting appropriate rest can also help alleviate tracheitis-related cough.
