This study will evaluate the use of topical 5 or 10% sinecatechins, a botanical drug derived from green tea for the alleviation of sexual pain in the area around the vaginal opening (the vulvar vestibule), that is a main source of pain during sexual contact or dyspareunia, in postmenopausal women, with vulvovaginal atrophy. Women may or may not be using estrogens. Half of the women will receive the study drug, 5 or 10% sinecatechins and half will receive placebo. In addition to the reduction or elimination of pain upon penetration, women may also experience increase in lubrication, arousal and intensity of orgasm
Topical Veregen (15% sinecatechins) is an FDA approved botanical drug derived from green tea and is approved to be used as multiple doses, three times a day to treat all visible external genital warts. Topical green tea ointment has been shown to alleviate pain and improve wound healing in the vulvar vestibule for women who have had a recent episiotomy in the medical literature. In private clinical practice, dilute Veregen, sinecatechins ointment, has been effective in alleviating , sexual pain, vulvar vestibular pain, dyspareunia, in postmenopausal women as well as improving overall sexual satisfaction,( increasing lubrication, arousal and quality of orgasm). In this study, dilute Veregen, (5 or 10% sinecatechins) or placebo is being applied, as a single dose, topically, three times/week up to once a day, to alleviate pain in the vulvar vestibule, penetration pain, upon sexual contact or other manipulation of this area in postmenopausal women. Women are eligible whether or not they are currently using any form of estrogen or other hormonal treatments (eg. DHEA). Please note that women not using estrogen or who maybe taking aromatase inhibitors, tamoxifen, SERMS, are also eligible to be included.

Numerical Rating Scale for Pain
Scale Title: Numerical Pain Scale to measure overall pain perceived from vulvar vestibule. Minimum value of scale: 0; Maximum value of scale: 10. Subjects were asked to rate from 0 to 10 pain perceived from their vulvar vestibule. The mean (standard error) for Numerical Pain Scale at each visit was calculated. A higher Numerical Rating Score means worse outcome and lower Numerical Rating Score means a better outcome. The following Numerical Rating Scale categories for Pain definition were utilized: 0=no pain, 1-3=mild pain, 4-6=moderate pain; 7-9=significant pain and 10=severe pain.
Time frame: Numerical Rating Scale for pain was assessed at Visit 1 (initial visit); Visit 2 (at 2 weeks), and Visit 3 (at 4 weeks).
Q-tip Test Test for Pain on the Vulvar Vestibule
Scale Title: Q-tip test of vulvar vestibular pain. Minimum value of scale: 0; Maximum value of scale: 10. Subjects were asked to rate from 0 to 10 pain perceived from their vulvar vestibule. The mean (standard error) for Q-tip test at each visit was calculated. A higher Q-tip score means worse outcome and lower Numerical Rating Score means a better outcome. The following Q-tip test categories for Pain definition were utilized: 0=no pain, 1-3=mild pain, 4-6=moderate pain; 7-9=significant pain and 10=severe pain.
Time frame: Q-tip test score for pain was assessed at Visit 1 (initial visit); Visit 2 (at 2 weeks), and Visit 3 (at 4 weeks).
