Abstract | BACKGROUND: METHODS: Endometrial-like lesions were induced in rats by autotransplantation of uterine tissue into the peritoneal cavity. Dienogest 0.3 or 1.0 mg/kg/day, danazol 100 mg/kg/day, or vehicle control were administered orally for 28 days. Changes in endometrial-like lesion size during treatment were assessed at laparotomy. Uterine horn weight was also measured as an index of the estrogenic effects of treatment. RESULTS:
Dienogest 0.3 mg/kg/day significantly reduced the total endometrial lesion area, with an effect equivalent to danazol 100 mg/kg/day. Unlike dienogest 1.0 mg/kg/day, dienogest 0.3 mg/kg/day had no effect on uterine horn weight, indicating an absence of estrogenic effects for this dose in rodents. CONCLUSION:
Dienogest 0.3 mg/kg/day for 28 days demonstrated potent inhibitory activity on the growth of endometrial tissue in this model, providing supportive evidence for the efficacy of dienogest in lesion reduction.
