Patients with phlegm in the throat often suffer from acute and chronic inflammatory diseases of the mucous membrane of the throat. Patients can take some oral Chinese medicines that have the effect of clearing the throat and improving the throat, such as sweet orange and plum tablets and golden voice and throat pill. If the phlegm is thicker, you can also take oral medications to help dissolve phlegm, such as eucalyptus citrus pinin enteric soft capsule, aminoglutethimide hydrochloride tablets, etc. Patients themselves need to pay attention to drink more water to keep the mucous membrane of the throat clean and moist. Some patients who have obvious manifestations of purulent sputum need further oral antibiotic drugs to treat and improve, such as cefprozil tablets, cefaclor extended-release tablets, levofloxacin tablets, etc., which can reduce the production of inflammatory secretions from the underlying cause of infection.
