Yuliprist Uses, Dosage, Side Effects, Food Interaction and all others data.

Yuliprist acetate is a selective progesterone receptor modulator. It acts by blocking the receptor of a hormone in the body called progesterone, which is involved in controlling the growth of the lining of the womb. In some women, progesterone may promote the growth of fibroids, which may cause symptoms such as heavy uterine bleeding, anaemia and abdominal pain. When progesterone activity is blocked, fibroid cells stop dividing and eventually die which reduces the size of the fibroids and reduces the symptoms caused by them.

Yuliprist is a selective, reversible progestin receptor modulator and its tissue targets include the uterus, cervix, ovaries, and hypothalamus. Yuliprist may act as an agonist or antagonist in the presence or absence of progesterone based on the tissue target. If given mid-follicular phase, development of the follicle growth is delayed and estradiol concentrations decrease. If given at the time when luteinizing hormone peaks, follicular rapture is delayed by several days. If given early-luteal phase, a decrease in endometrial thickness can be observed.

Uses

Yuliprist Acetate is used before surgery to treat moderate to severe symptoms of uterine fibroids, which are noncancerous (benign) tumors of the womb (uterus). Yuliprist Acetate is used in adult women who have not yet reached menopause.

Yuliprist is also used to associated treatment for these conditions: Moderate Uterine Fibroids, Severe Uterine Fibroids, Emergency Contraception

How Yuliprist works

The exact mechanism of action of ulipristal has been heavily debated . On one hand, the majority of official prescribing information labels, monographs, and prior research studies for ulipristal indicated as an emergency contraceptive suggest that its primary mechanism of action revolves around inhibiting or delaying ovulation by suppressing surges in LH that result in the postponement of follicular rupture .

Conversely, some of the latest investigations pertaining to ulipristal's mechanism of action as an emergency contraceptive propose that it principally elicits its action by preventing embryo implantation, as opposed to preventing ovulation . Although previous investigations have shown that ulipristal essentially has the ability to prevent ovulation equivalent to placebo (ie. null effect or ability) when administered during LH peaks one to two days before ovulation, the agent still demonstrates a stable and consistently high contraceptive effect of approximately >=80% when used at this time . Subsequently, current studies attempt to investigate how ulipristal could elicit emergency contraception via ovulation prevention under circumstances where ovulation had already clearly been observed . Endometrial biopsy samples studied from such circumstances in such investigations subsequently show that the administered ulipristal causes endometrial tissue to become inhospitable and unsuitable for embryo implantation where a variety of genes characteristic of receptive, pro-gestational endometrium are downregulated .

Nevertheless, most if not all proposed mechanisms commonly agree that ulipristal ultimately demonstrates its pharmacological effects by binding to human progesterone receptors and prevents natural, endogenous progesterone from occupying such receptors . Regardless, however, considering current and on-going research into ulipristal's ability to prevent embryo implantation, the notion that the medication can elicit post-fertilization effects potentially raises alerts and/or ethical debates over the use of ulipristal owing to potential abortifacient activity , which is considered to be on par or equipotent to that of mifepristone . Attention should be drawn to the fact that some prescribing information, however, such as the US FDA label for ulipristal indicated for emergency contraception, has included new supplementary commentary since 2018 that directly warns about ulipristal not being indicated for termination of existing pregnancies and suggesting that ulipristal use may confer alterations to the endometrium that may affect implantation and contribute to efficacy .

In the treatment of fibroids, ulipristal has been shown to exert direct actions on fibroids reducing their size through inhibition of cell proliferation and induction of apoptosis.
