CONCLUSION: Based on medicinal property combination modes, the authors screened topiramate's new functions according to e of TCM clinical experience, discovered topiramate's therapeutic effects on diabetes, hypertension and lung cancer in addition to epilepsy, and explore new drug function according to medicinal property combination modes, which could help greatly shorten the new drug R&D period.
