Low-dose 17 beta-estradiol vaginal tablets in the treatment of atrophic vaginitis: a double-blind placebo controlled study.
The aim of the study was to investigate the effect of 25 micrograms 17 beta-estradiol administered as a small vaginal tablet (Vagifem, Novo Nordisk A/S) on the symptoms of the vagina related to atrophy. The study was designed as a double-blind randomized placebo controlled study running for 12 weeks. The women were treated once daily for 2 weeks with the active or the placebo tablet. During the subsequent 10 weeks the women were treated twice a week. One hundred and sixty-four women were included. Ten dropped out for minor reasons, most of these due to lack of effect in the placebo group. In the Vagifem group 78.8% were suffering from moderate to severe atrophy of the vagina, compared with 81.9% in the placebo group. After 2 weeks the percentages were 14.3 and 35.3, respectively. After 12 weeks of treatment, 10.7% in the Vagifem group compared with 29.9% in the placebo group had moderate to severe atrophy (P less than 0.0001). A substantial part of the women complained about subjective symptoms such as vaginal dryness and dyspareunia. After 12 weeks of treatment, a significant improvement was found in the Vagifem group (P less than 0.002). Before treatment 53.1% in the treatment group and 41.0% in the placebo group were suffering from urological symptoms. After 2 weeks, 60.5% of the women in the Vagifem group underwent a change for the better compared to 35.3% in the placebo group. After 12 weeks of treatment the percentages in the two groups feeling an improvement were 62.8% and 32.4%. In this study local low-dose treatment with 25 micrograms 17 beta-estradiol was found to have a significant effect on the postmenopausal urogenital symptoms related to atrophy.
