The U.S. Food and Drug Administration approved Intrarosa (prasterone) to treat women experiencing moderate to severe pain during sexual intercourse (dyspareunia), a symptom of vulvar and vaginal atrophy (VVA), due to menopause.
Intrarosa is the first FDA approved product containing the active ingredient prasterone, which is also known as dehydroepiandrosterone (DHEA).
During menopause, levels of estrogen decline in vaginal tissues, which may cause a condition known as VVA, leading to symptoms such as pain during sexual intercourse.
Efficacy of Intrarosa, a once-daily vaginal insert, was established in two 12-week placebo-controlled clinical trials of 406 healthy postmenopausal women, 40 to 80 years of age, who identified moderate to severe pain during sexual intercourse as their most bothersome symptom of VVA. Women were randomly assigned to receive Intrarosa or a placebo vaginal insert. Intrarosa, when compared to placebo, was shown to reduce the severity of pain experienced during sexual intercourse.
The safety of Intrarosa was established in four 12-week placebo-controlled trials and one 52-week open-label trial. The most common adverse reactions were vaginal discharge and abnormal Pap smear.
Although DHEA is included in some dietary supplements, the efficacy and safety of those products have not been established for diagnosing, curing, mitigating, treating or preventing any disease.
Intrarosa is marketed by Quebec-based Endoceutics Inc.
