Comparative Observation on the Effects of Radix tripterygium Hypoglaucum tablet and tripterygium glycosides tablet in Treating Erosive Oral Lichen Planus

Objective: To compare the therapeutic effects of Radix tripterygium hypoglaucum tablet (THT) and tripterygium glycosides tablet (TGT) in treating erosive oral lichen planus(EOLP).Methods: The patients were randomized into two groups, and they were treated with THT (n=47) or TGT (n=47), respectively. The therapeutic effects were evaluated after 3 months ***: For the patients of grade 1, the total efficacy in TGT group was 85.71%, compared with 52.38% in THT group, the efficacy was statistically greater in the group receiving TGT (P=0.043). However, for the patients of grade 2, the difference was not statistically significant (P=0.173).Conclusion: TGT is more effective in treating EOLP than THT for grade 1 patients. However, TGT is not suitable for patients of child bearing age.
