Abstract:

OBJECTIVE To research the regularity of drug use of patents in force of traditional Chinese herbal compounds in preventing and treating respiratory diseases, and provide a reference for the new Chinese drug development and evidence for the patent protection. METHODS With patents in force for 5 years of traditional Chinese medicine compounds in preventing and treating respiratory diseases as the study object, the frequency analysis was made for studying their core drug use, efficacy, channel tropism and drug compatibility. RESULTS There were 22 kinds of herbs such as Lonicerae Japonicae Flos, Glycyrrhizae Radix et Rhizoma, Scutellariae Radix used frequently in patents in force of traditional Chinese medicine compounds in preventing and treating respiratory diseases.
