Linzagolix, sold under the brand name Yselty, is a medication used in the treatment of uterine fibroids. [1] [6] Linzagolix is a small-molecule, non-peptide, orally active gonadotropin-releasing hormone antagonist (GnRH antagonist) developed by Kissei Pharmaceutical and ObsEva. [7] [8] [2]
In June 2022, it was approved for medical use in the European Union and in the United Kingdom. [1] [5] [9]
Linzagolix is indicated for treatment of moderate to severe symptoms of uterine fibroids in adult women of reproductive age. [1]
Linzagolix is available as linzagolix choline, the choline salt of linzagolix, in the form of 100 and 200 mg film-coated oral tablets. [6]
Linzagolix acts as a selective antagonist of the GnRH receptor, the biological target of GnRH. [6] By blocking this receptor, linzagolix prevents GnRH-mediated secretion of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and prevents them from signaling the gonads to produce sex hormones including estrogens, progesterone, and androgens. [6] [10]
In clinical studies, linzagolix fully suppressed estradiol levels (median <20 pg/mL) in women at a dosage of 200 mg/day, whereas partial suppression of estradiol levels (median 20–60 pg/mL) occurred at a dosage 100 mg/day. [6] Progesterone levels were also variably suppressed with these dosages. [6]
The elimination half-life of linzagolix with repeated administration is approximately 15 hours. [6]
On 16 December 2021, and on 22 April 2022, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Yselty, intended for the treatment of symptoms of uterine fibroids. [11] The applicant for this medicinal product is ObsEva Ireland Ltd. [11] Linzagolix was approved for medical use in the European Union in June 2022. [1] [5]
Linzagolix is sold under the brand name Yselty. [6]
Linzagolix is available in the European Union and in the United Kingdom. [6] [9]
Goserelin, sold under the brand name Zoladex among others, is a medication which is used to suppress production of the sex hormones, particularly in the treatment of breast cancer and prostate cancer. It is an injectable gonadotropin releasing hormone agonist.
Leuprorelin, also known as leuprolide, is a manufactured version of a hormone used to treat prostate cancer, breast cancer, endometriosis, uterine fibroids, for early puberty, or as part of transgender hormone therapy. It is given by injection into a muscle or under the skin.
Nafarelin, sold under the brand name Synarel among others, is a gonadotropin-releasing hormone agonist medication which is used in the treatment of endometriosis and early puberty.

The medication is used as a nasal spray two to three times per day.
Buserelin, sold under the brand name Suprefact among others, is a medication which is used primarily in the treatment of prostate cancer and endometriosis. It is also used for other indications such as the treatment of premenopausal breast cancer, uterine fibroids, and early puberty, in assisted reproduction for female infertility, and as a part of transgender hormone therapy. In addition, buserelin is used in veterinary medicine. The medication is typically used as a nasal spray three times per day, but is also available for use as a solution or implant for injection into fat.
Norethisterone acetate (NETA), also known as norethindrone acetate and sold under the brand name Primolut-Nor among others, is a progestin medication which is used in birth control pills, menopausal hormone therapy, and for the treatment of gynecological disorders. The medication available in low-dose and high-dose formulations and is used alone or in combination with an estrogen. It is ingested orally.
Triptorelin, sold under the brand name Decapeptyl among others, is a medication that acts as an agonist analog of gonadotropin-releasing hormone, repressing expression of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).
A gonadotropin-releasing hormone agonist is a type of medication which affects gonadotropins and sex hormones. They are used for a variety of indications including in fertility medicine and to lower sex hormone levels in the treatment of hormone-sensitive cancers such as prostate cancer and breast cancer, certain gynecological disorders like heavy periods and endometriosis, high testosterone levels in women, early puberty in children, as a part of transgender hormone therapy, and to delay puberty in transgender youth among other uses. It is also used in the suppression of spontaneous ovulation as part of controlled ovarian hyperstimulation, an essential component in IVF. GnRH agonists are given by injections into fat, as implants placed into fat, and as nasal sprays.
Gonadotropin-releasing hormone antagonists are a class of medications that antagonize the gonadotropin-releasing hormone receptor and thus the action of gonadotropin-releasing hormone (GnRH). They are used in the treatment of prostate cancer, endometriosis, uterine fibroids, female infertility in assisted reproduction, and for other indications.
Ganirelix acetate, sold under the brand names Orgalutran and Antagon among others, is an injectable competitive gonadotropin-releasing hormone antagonist. It is primarily used in assisted reproduction to control ovulation. The drug works by blocking the action of gonadotropin-releasing hormone (GnRH) upon the pituitary, thus rapidly suppressing the production and action of LH and FSH. Ganirelix is used in fertility treatment to prevent premature ovulation that could result in the harvesting of eggs that are too immature to be used in procedures such as in vitro fertilization.
Cetrorelix, or cetrorelix acetate, sold under the brand name Cetrotide, is an injectable gonadotropin-releasing hormone (GnRH) antagonist. A synthetic decapeptide, it is used in assisted reproduction to inhibit premature luteinizing hormone surges The drug works by blocking the action of GnRH upon the pituitary, thus rapidly suppressing the production and action of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In addition, cetrorelix can be used to treat hormone-sensitive cancers of the prostate and breast and some benign gynaecological disorders. It is administered as either multiple 0.25 mg daily subcutaneous injections or as a single-dose 3 mg subcutaneous injection. The duration of the 3 mg single dose is four days; if human chorionic gonadotropin (hCG) is not administered within four days, a daily 0.25 mg dose is started and continued until hCG is administered.
Dienogest, sold under the brand name Visanne among others, is a progestin medication which is used in birth control pills and in the treatment of endometriosis. It is also used in menopausal hormone therapy and to treat heavy periods. Dienogest is available both alone and in combination with estrogens. It is taken by mouth.
Deslorelin, sold under the brand name Suprelorin among others, is an injectable gonadotropin releasing hormone superagonist which is used in veterinary medicine for various indications.
An estrogen-dependent condition can be that relating to the differentiation in the steroid sex hormone that is associated with the female reproductive system and sex characteristics. These conditions can fall under the umbrella of hypoestrogenism, hyperestrogenim, or any sensitivity to the presence of estrogen in the body.
Elagolix, sold under the brand name Orilissa, is a gonadotropin-releasing hormone antagonist medication which is used in the treatment of pain associated with endometriosis in women. It is also under development for the treatment of uterine fibroids and heavy menstrual bleeding in women.

Sufugolix (INNTooltip International Nonproprietary Name, BANTooltip British Approved Name) (developmental code name TAK-013) is a non-peptide, orally-active, selective antagonist of the gonadotropin-releasing hormone receptor (GnRHR) (IC50Tooltip Half-maximal inhibitory concentration = 0.1 and 0.06 nM for affinity and in vitro inhibition, respectively). It was under development by Takeda for the treatment of endometriosis and uterine leiomyoma and reached phase II clinical trials for both of these indications, but was subsequently discontinued. It seems to have been supplanted by relugolix (TAK-385), which is also under development by Takeda for the treatment of these conditions and has a more favorable drug profile (including reduced cytochrome P450 inhibition and improved in vivo GnRHR antagonistic activity) in comparison.
A GnRH modulator, or GnRH receptor modulator, also known as an LHRH modulator or LHRH receptor modulator, is a type of medication which modulates the GnRH receptor, the biological target of the hypothalamic hormone gonadotropin-releasing hormone. They include GnRH agonists and GnRH antagonists. These medications may be GnRH analogues like leuprorelin and cetrorelix – peptides that are structurally related to GnRH – or small-molecules like elagolix and relugolix, which are structurally distinct from and unrelated to GnRH analogues.
High-dose estrogen therapy (HDE) is a type of hormone therapy in which high doses of estrogens are given. When given in combination with a high dose of progestogen, it has been referred to as pseudopregnancy. It is called this because the estrogen and progestogen levels achieved are in the range of the very high levels of these hormones that occur during pregnancy. HDE and pseudopregnancy have been used in medicine for a number of hormone-dependent indications, such as breast cancer, prostate cancer, and endometriosis, among others. Both natural or bioidentical estrogens and synthetic estrogens have been used and both oral and parenteral routes may be used.
