This study suggests that low dose estradiol may be effective in treating overactive bladder – “Randomized trial of estradiol vaginal ring versus oral oxybutynin for the treatment of overactive bladder” (Menopause. 2011 Sep;18(9):962-6).
OBJECTIVE: The aim of this study was to compare the efficacy of the ultralow-dose estradiol vaginal ring with that of oral oxybutynin in the treatment of overactive bladder in postmenopausal women.
METHODS: Postmenopausal women with an overactive bladder were recruited from the general gynecology clinic. Participants were randomized to receive either the ultralow-dose estradiol vaginal ring or oral oxybutynin for 12 weeks. The primary outcome was a decrease in the number of voids in 24 hours. The secondary outcomes were quality-of-life questionnaires, vaginal pH levels, and vaginal maturation index.
RESULTS: Fifty-nine women were enrolled. Thirty-one were randomized to receive oxybutynin, whereas 28 received the estradiol vaginal ring. Women who received oxybutynin had a mean decrease of 3.0 voids per day, and women who received the vaginal ring had a mean decrease of 4.5 voids per day, with no significant difference between the groups. There was a significant improvement in Urogenital Distress Inventory and Incontinence Impact Questionnaire scores in both groups, with no significant difference in improvement between the two groups.
CONCLUSIONS: Ultralow-dose estradiol-releasing vaginal ring and oral oxybutynin seem to be similarly effective in decreasing the number of daily voids in postmenopausal women with overactive bladder.More treatment options for overactive bladder in postmenopausal women.Eckler K.

We have the ability to custom make low-dose estradiol vaginal suppositories. This option may help to increase medication compliance, and save patients significant money.
