See the DrugPatentWatch profile for Relugolix
Relugolix, estradiol, and norethisterone acetate is a combination oral contraceptive pill [1]. It is also available as a monotherapy drug for other indications [2].
What is Relugolix estradiol norethisterone acetate used for?
The combination of relugolix, estradiol, and norethisterone acetate is used as an oral contraceptive to prevent pregnancy [1]. Relugolix is a gonadotropin-releasing hormone (GnRH) receptor antagonist, while estradiol is a form of estrogen and norethisterone acetate is a progestin [2]. Together, these components work to prevent ovulation, thicken cervical mucus, and alter the uterine lining, making pregnancy less likely [1].
How does Relugolix estradiol norethisterone acetate work?
Relugolix inhibits the action of GnRH, which in turn reduces the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland [2]. This suppression prevents the development and release of an egg from the ovary (ovulation) [1]. Estradiol and norethisterone acetate supplement the hormonal environment, further contributing to the contraceptive effect and stabilizing the uterine lining [1].
