Ulipristal acetate followed by LNG-IUS significantly reduces HMB, with variable reductions in fibroid size, often controlling symptoms to such a degree that surgery may be avoided. Progesterone receptor modulator CDB induces extracellular matrix metalloproteinase inducer in cultured human uterine leiomyoma cells. Data on the benign histologic endometrial changes induced by ulipristal acetate are reassuring, as they tend to be spontaneously resolved within a few months after the end of the week treatment [ 9 , 10 ].

Effects of progesterone on uterine leiomyoma growth and apoptosis. Laparoscopic surgery requires skills that are not commonplace and there are limitations on the size and number of fibroids that can be treated by this modality. Nine women were fitted with a LNG-IUS following ulipristal acetate, three were referred to secondary care for consideration for surgical treatment, one had repeated courses of ulipristal acetate, one became amenorrhoeic due to the menopause, and one incidentally developed breast cancer and had no further treatment for HMB. These regimens are as effective as leuprolide acetate in controlling uterine bleeding and induce significantly fewer hot flashes [ 7 ]. Other medical options that reduce fibroid volume include danazol, mifepristone, aromatase inhibitors, and raloxifene. The co-primary efficacy endpoints were control of uterine bleeding and reduction of fibroid volume at week 13, after which patients could undergo surgery.

Uterine fibroid growth depends on the ovarian steroids estrogen and progesterone [ 1 ]. View at Google Scholar M.

Ulipristal Acetate: a novel medical therapy for uterine fibroids

Fibroid size was measured at presentation and three months after treatment with ulipristal acetate. This case series included 15 women. These include hot flushes, headache, functional ovarian cysts, vertigo, nausea, acne, sweating, muscle pain and xcetate.

It reversibly blocks the progesterone receptor in its target tissues uterus, cervix, ovaries, hypothalamus and acts as a potent, orally active anti-progestational agent.


Effectiveness and safety of medium-term use of ulipristal acetate has recently been shown. This is related to cystic glandular dilation, not endometrial hyperplasia.

The patient persisted with amenorrhea from the beginning of the treatment, and no side effects were reported following treatment. The status of current medical treatments for uterine fibroids Gonadotropin-releasing hormone GnRH analogues have been the most widely used medical treatment; however, while they do cause fibroid regression, they can only be used in the short term, as temporizing measures in the perimenopausal woman, or preoperatively to reduce fibroid size and influence the type of surgery, restore hemoglobin levels and apparently reduce blood loss at operation.

Conflict of Interests The authors have no conflict of interests and received no financial support for this work. Thus, the spontaneous pregnancy after UA to reduce fibroid size may support the potential clinical utility of this selective progesterone receptor modulator in the management of women with pregnancy desire and uterine fibroids after a prior myomectomy.

Although the exact etiology of fibroids is not well established, it is known that these tumors depend on sex hormones for their growth and several risk factors have been identified such as early menarche, nulliparity and family history.

No biopsy demonstrated atypical hyperplasia. PEARL I compared treatment with oral UA for up to 13 weeks at a dose of 5 mg per day 96 women or 10 mg per day 98 women with placebo 48 women in patients with fibroids, menorrhagia and anemia 8.

Given the choice, many women would opt to avoid major surgery such as myomectomy or hysterectomy, or indeed even the less invasive procedures such as UAE or MRgFUS. Follow-Up Examinations Monthly follow-up visits were acetatr out. Case Reports in Obstetrics and Gynecology. Materials and Methods 2.

Myomectomy is a major operation with associated morbidity and indeed mortality risks. The management of uterine fibroids in women with reproductive desire is still controversial [ 46 ]. They decreased the cell viability; suppressed the expression of growth factors, angiogenic factors and their receptors in those cells; and induced apoptosis.

The optimal treatment for patients with symptomatic uterine fibroids and pregnancy desire remains unknown [ 3468 ]. Data on the benign histologic endometrial changes induced by ulipristal acetate ulipristxl reassuring, as they tend to be spontaneously resolved within a few months after the end of the week treatment [ 910 ]. Accordingly, oral progestin may promote fibroid growth and induce abnormal bleeding [ 7 ].

The spectrum of endometrial pathology induced by progesterone receptor modulators. It is also as effective as leuprolide acetate for controlling uterine bleeding, uoipristal with significantly fewer hot flashes [ 7 ]. Talaulikar VS, Manyonda I. There is undoubtedly an urgent need for simple and effective medical therapies to treat the very common disease of the female reproductive age group that is symptomatic fibroids.
