ABSTRACT

Objective:To analyze the functions and indications， formulation， dosage form and medication characteristics of Chinese patent medicines in the 2020 edition of<italic> Chinese Pharmacopoeia</italic> （part Ⅰ） for treating cough of children， and to provide ideas for the clinical rational application and provide reference for the research and development of new cough medicines for children. Method:The name， dosage form， formulation， functions and indications， usage and dosage， and other information of Chinese patent medicines for cough were collected from the 2020 edition of <italic>Chinese Pharmacopoeia </italic>（part Ⅰ）， then relevant information was input into Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine v2.0， and data analysis and mining were carried out through the analysis module of prescription medication rule， VOSviewer 1.6.14 was used to make drug clustering network view of Chinese patent medicines for the treatment of exogenous wind cold， exogenous wind heat and phlegm heat cough. Result:In the 2020 edition of <italic>Chinese Pharmacopoeia </italic>（part Ⅰ）， a total of 75 kinds of Chinese patent medicines for treating cough of children were collected， including 34 kinds of Chinese patent medicines for adults and children， 41 kinds of Chinese patent medicines for children only. There were 7 types of traditional Chinese medicine syndromes， such as wind-cold attacking the lung， wind-heat invading the lung and phlegm-heat obstructing the lung. There were 45 Chinese patent medicines for treating exogenous cough， accounting for 60%， among which 35 kinds were used for exogenous wind-heat cough and 10 kinds were used for wind-cold cough. There were 30 kinds of Chinese patent medicines for treating internal injury cough， including 19 kinds of medicines for phlegm heat obstructing the lung， 4 kinds of medicines for phlegm dampness containing the lung and phlegm food stagnation， 2 kinds of medicines for Yin-deficiency lung heat， 1 kind of medicine for the lung and spleen Qi-deficiency. The formulation analysis showed that Glycyrrhizae Radix et Rhizoma， Platycodonis Radix， Scutellariae Radix， Armeniacae Semen Amarum and Citri Reticulatae Pericarpium appeared frequently， which were mainly cold， bitter and sweet herbs， mainly belonged to the lung and stomach meridians. According to the analysis of administration and dosage forms， 71 kinds of Chinese patent medicines were administered through gastrointestinal tract， including 20 kinds of granules， 15 kinds of oral liquids， others included syrups， pills， capsules， tablets， powers， etc. Only 2 suppositories and 2 injections were administered by nongastrointestinal tract. The usage and dosage of most Chinese patent medicines were not clear. Conclusion:In the 2020 edition of <italic>Chinese Pharmacopoeia </italic>（part Ⅰ）， the main syndromes of Chinese patent medicines for cough of children are exogenous wind-heat and phlegm-heat obstruction in the lung. Most of the Chinese medicines are cold， bitter and sweet， and their meridians are mainly lung and stomach meridians. Scutellariae Radix， Lonicerae Japonicae Flos and Forsythiae Fructus are the most common medicines of exogenous wind heat syndrome. Perillae Folium， Citri Reticulatae Pericarpium and Ephedrae Herba are the most common medicines of exogenous wind cold syndrome. Meanwhile， Scutellariae Radix， Platycodonis Radix and Armeniacae Semen Amarum are the most common medicines of phlegm heat obstructing the lung syndrome. At present， the dosage forms of Chinese patent medicines used for treating cough of children are too few and the dosage labeling is not comprehensive， so it is necessary to further strengthen the research and development of new Chinese medicines suitable for characteristics of children.
