Methoxyphenamine is a drug commonly used in the treatment of coughs in respiratory diseases. It is not an antibiotic, but a compound preparation containing methoxyphenamine hydrochloride, noscapine, aminophylline and chlorpheniramine maleate. Among the ingredients of this drug, methocarbamol inhibits bronchospasm and relieves coughing during asthma attacks. Narcodine is a peripheral cough suppressant that suppresses coughing. Aminophylline inhibits bronchial spasm and also inhibits swelling of the bronchial mucosa, relieving coughing during asthma attacks and making it easier to cough up sputum. Chlorpheniramine maleate is an anti-allergic drug that suppresses cough caused by inflammation of the upper respiratory tract. The combination of these ingredients not only reduces coughing caused by throat and bronchitis, but also relieves coughing during asthma attacks and facilitates sputum excretion. However, none of the main ingredients are antibiotics, and none of them have antibacterial activity. Compound Methoxyphenamine Capsules are mainly used clinically for bronchial asthma and wheezing bronchitis, as well as other respiratory diseases that cause cough and sputum and other symptoms of wheezing.
