Children with colds, coughs, and runny noses develop because of viral or bacterial infections that cause inflammation of the upper respiratory tract, which means that the nasal cavity and throat become infected. These locations will not only have congestion and edema, but also secrete a lot of inflammatory exudates, for example, the nasal cavity will secrete a lot of inflammatory exudates to form nasal mucus, and in the throat there will be congestion and edema and inflammatory exudates, which are more irritating and can easily induce coughing. Generally, according to the type of infection, you need to choose appropriate anti-inflammatory drugs to carry out anti-inflammatory treatment, such as viral infections need to use busulfan anti-inflammatory oral liquid or ribavirin granules, if it is a bacterial infection, you can use antibiotics for treatment. For more serious cases of runny nose, you can use cold medicines, such as aminophenol pseudomal dispersible tablets.
