Guaimemetamol Syrup is indicated for the treatment of acute and chronic bronchitis, bronchial asthma, and allergic or other respiratory diseases that cause cough symptoms. The main ingredients are dextromethorphan hydrobromide, methylephedrine hydrochloride and guaiacol glycerol ether, etc. Dextromethorphan hydrobromide has a significant effect on suppressing the human central nervous system and relieving reflex cough. Guaiacol glycerol ether is an expectorant, which has a diluting effect on the phlegm produced by local inflammation, allowing the phlegm to be more easily expelled from the body and preventing the appearance of airway and lung blockage symptoms. Methylephedrine hydrochloride can promote the secretion of adrenaline hormone in the body, thus playing a positive role in dilating the bronchial tubes and improving respiratory function. For specific medication regimen, it is recommended to visit a regular hospital for examination and medication treatment under the guidance of a doctor.
