Kyoto Nianci 'an honey refining Chuanbei Pipa cream has the functions of moistening lung and resolving phlegm, relieving cough and asthma, protecting throat and relieving sore throat, promoting fluid production and invigorating qi, and regulating heart and reducing fire. The medicine mainly plays a local role by adsorbing on tracheal mucosa. It is recommended to drink water after taking it for half an hour. In fact, cough syrup is a kind of over-the-counter medicine that is often used in daily life. Because of its good taste and convenient administration, it is loved by cough patients, especially children and the elderly. Some people are used to drinking a lot of water immediately after taking syrup, thinking that this can quickly get rid of the special taste of the medicine and send the liquid medicine into the gastrointestinal tract as soon as possible. In fact, this is not conducive to the efficacy of cough syrup.

This is because, on the one hand, the antitussive effect of cough syrup depends on gastrointestinal absorption, on the other hand, it depends on the syrup covering the surface of pharyngeal mucosa to directly reduce the irritation of inflammation. If you drink plenty of water immediately after taking the medicine, it will first reduce the drug concentration in the pharynx, and then dilute the gastric juice, which will affect the absorption of drugs in the gastrointestinal tract. Therefore, some doctors will advise patients not to drink water for at least 5 minutes after drinking syrup to improve the curative effect. However, if the thick syrup is too irritating to the pharynx and even causes discomfort, it is another matter.
