Swissmedic approves Intrarosa® (prasterone) for the treatment of vulvovaginal atrophy in postmenopausal women

A novel drug for the treatment of vulvovaginal atrophy based on prasterone (DHEA)


Geneva, the 02.06.2020 – On 19.05.2020, Swissmedic, the Swiss Agency for Therapeutic Products, granted a marketing authorization for the active substance prasterone for the local treatment of vulvovaginal atrophy in post-menopausal women. This medicine will be marketed as Intrarosa®, in the form of a vaginal insert containing 6.5 mg of prasterone. Prasterone is also known as dehydroepiandrosterone (DHEA).

The lack of sex hormones associated with menopause can cause thinning and dryness of the tissues of the vulva and vagina. DHEA is naturally secreted and is used to produce estrogen and androgen in the vagina. Intrarosa® can therefore compensate for insufficient natural sex hormones in women’s vagina after menopause. This medicine will physiologically improve the symptoms of vulvovaginal atrophy, including vaginal dryness, pain during sexual activity (dyspareunia), irritation and itching.

It is estimated that more than 50% of postmenopausal women suffer from vulvovaginal atrophy (1)  (part of the genitourinary syndrome of menopause) but this topic remains taboo between women and their physicians (2). Yet evidence shows that vulvovaginal atrophy negatively affects women’s quality of life on a daily basis (1) .

About Intrarosa®

Intrarosa® is a vaginal insert containing 6.5 mg of prasterone (DHEA), available in a pack of 28 inserts, with 6 reusable applicators. The recommended dose is a vaginal insert once a day at bedtime, with – or without – the use of the applicator provided (3) .

Prasterone is a naturally occurring steroid compound that is inactive by itself. After intravaginal administration, prasterone is converted to estrogen and androgen within the vaginal cells. Thus, Intrarosa® differs from estrogenic preparations as it also provides androgens that have a complementary effect on vaginal health. The sex hormones produced from prasterone inside the vaginal cells are then also inactivated locally in the same cells.  That avoids the release of active sex steroids in the circulation (4) . Intrarosa® enables the application of this mechanism of action, also known as intracrinology (5) , in an innovative way for treating vulvovaginal atrophy in postmenopausal women.

Intrarosa® Development

Intrarosa® was developed in Quebec by Endoceutics, a company founded by the late Dr. Fernand Labrie (1937-2019). The product has been approved for sale in the United States, Europe and Canada since 2016, 2018 and 2019, respectively. Labatec is the selected partner to market Intrarosa in Switzerland. “Labatec is pleased to provide access in Switzerland to the first local DHEA-based treatment for vulvovaginal atrophy after menopause,” said Faisal Darwazeh, CEO at Labatec. “The inclusion of this innovative product in our portfolio illustrates Labatec’s strong commitment to improving women’s health.

The efficacy of Intrarosa® on dyspareunia and vaginal dryness, two symptoms of vulvovaginal atrophy due to menopause, as well as on three markers of vaginal health (vaginal pH and percentage of parabasal and superficial cells), has been demonstrated in several Phase III placebo-controlled clinical studies(6) .

The safety of Intrarosa® has been documented in several clinical studies, including a 52-week study (7) .
