Evaluation of the Efficacy and Safety of Hyaluronic Acid Vaginal Gel to Ease Vaginal Dryness. A Multicenter, Randomized, Controlled, Open-label, Parallel-group, Clinical Trial

This multicenter, randomized, controlled, open-label, parallel-group, 30-day study took place at four centers in China. The primary objective of this study was to assess the efficacy and safety of hyaluronic acid vaginal gel in treating vaginal dryness. In the current study we tested the hypothesis that the efficacy of hyaluronic acid vaginal gel was not inferior to that of estriol cream, with no clinically significant difference between them, in the treatment of vaginal dryness symptoms.
