Clinical Study of Vaginal Lactobacilli and Estriol (Gynoflor®) for Atrophic Vaginitis in Breast Cancer Patients - Full Text View

Purpose

The purpose of this study is to assess the longterm safety and efficacy of the vaginal application of Gynoflor®, an extremely low dosed estrogen therapy with lactobacilli, on atrophic vaginitis in postmenopausal breast cancer patients who have been treated with aromatase inhibitors.
