Objectives: Uterine fibroids are the most common benign tumors in women of reproductive age. Evidence suggest that ovarian steroid hormones, in particular, progesterone play a major role in promoting leiomyoma development and growth. For the last years there was an extensive research on selective progesterone receptor modulators and their use in therapy. Ulipristal acetate (UPA) is one of these modulators. The aim of this paper is to evaluate efficacy and safety of oral ulipristal acetate for the treatment in women with symptomatic uterine fibroids.
Methods: The study group comprised five patients with uterine fibroids. All patients received 5 mg of ulipristal acetate per day for three months.
Results: The total volume of fibroids decreased by 33-68%. In all patients during the administration of UPA significant reduction of menstrual bleeding was observed. Increase of endometrial thickness without clinical significance was observed in two patients. No significant side-effects were observed during the treatment period.
Conclusions: 1) The volume offibroids decreased from 33 to 68%. 2) The UPA administration effectively controlled excessive bleeding. 3) Treatment with UPA may modify the scope of the surgery. 4) UPA is a well-tolerated drug.

Background: The current regimen for early medication abortion in many countries is mifepristone and misoprostol, but mifepristone is relatively expensive and limited in many regions. Ulipristal acetate, with a similar chemical profile, might be an alternative. This proof-of-concept study evaluated ulipristal acetate and misoprostol for medication abortion through 63 days of gestation.

Introduction: Dysmenorrhea is a painful symptom associated with uterine contractions and menstrual bleeding and is treated by administering analgesic drugs. Since progesterone receptors (PRs) have a major role in regulating uterine tissues (myometrium and endometrium) physiology, oral contraceptives are used off-label for treating primary or secondary dysmenorrhea. The development of selective progesterone receptor modulators (SPRMs), a class of synthetic steroids with agonistic, antagonistic, or mixed effects in targeting PRs in different tissues, stimulated their possible clinical use for treating secondary dysmenorrhea related to uterine diseases (endometriosis, adenomyosis, uterine fibroids).

Endometriosis affects about 10 percent women in the reproductive age group globally and approximately 42 million in India. Managing the patient's pain symptoms associated with endometriosis appears to be the cornerstone in endometriosis disease management. The ideal medical treatment in endometriosis would be suppressing estradiol enough to alleviate symptoms of endometriosis but maintain sufficient levels to mitigate hypoestrogenic side effects.

Progesterone (P4) is a vital female sex hormone involved in various physiological processes, including the maintenance of the endometrium, mammary gland development, and bone health. Beyond its reproductive roles, P4 is implicated in the pathogenesis of hormone-dependent conditions like uterine fibroids, the most common benign tumors in women, which can severely affect quality of life and fertility. Traditionally, estrogen was considered the primary driver of fibroid growth, but recent research highlights the significant role of P4 in fibroid growth.
