Vulvo-vaginal atrophy (VVA) is a chronic condition affecting many postmenopausal women. Local estrogen treatment is recommended. Evaluating efficacy and safety of long-term VVA treatment with ultra-low-dose estriol gel, 120 postmenopausal VVA women were enrolled in a prospective study. They received the first cycle of 1 g/day vaginal gel containing 50 µg estriol for 3 weeks and then twice a week for 12 weeks. Moderate or severe VVA women received a second treatment cycle reaching treatment of 30 weeks. Vaginal pH measurement, subjective symptoms, and objective signs assessment of VVA, endometrial thickness and adverse events (AE) were recorded. Of the 99 women, completing the first phase, 43% experienced a complete VVA symptom relief, and 65% presented a milder VVA degree. After 30 weeks, VVA signs significantly improved (p<.01) compared with baseline and first phase results; total objective symptom evaluation including Schiller's test, flattening of folds and vaginal pH significantly improved (p<.01). At study endpoint, none of the patients had severe VVA, 93% had a positive response, 75% had a complete symptom, and sign resolution. No treatment-related endometrial AE were observed. Postmenopausal VVA long term-treatment with ultra-low-dose estriol vaginal gel is safe and effective.
