Cough, sputum and throat inflammation usually indicate that the patient has a respiratory tract infection, which requires oral anti-infective medication as well as symptomatic treatment with throat laxatives, expectorants and cough suppressants. If the cough is caused by bacterial infection, patients can take oral antibiotics such as amoxicillin, cefaclor, cefuroxime, azithromycin, levofloxacin hydrochloride or moxifloxacin hydrochloride for anti-inflammatory treatment, as well as oral laxative medications such as honey-refined Chuanbei loquat paste, blue scutellaria oral liquid and corresponding laxative tablets. Patients with significant cough also need to take oral cough suppressants, such as compound forcodine oral solution, compound licorice tablets, and compound methanamine capsules. Some patients may have increased airway sensitivity, and oral ketotifen or cetirizine hydrochloride tablets are needed to reduce the sensitivity of the airway.
