*

Pharmacology:-

This tablet is a combination of relugolix, estradiol (E2) and norethindrone acetate (NETA). Relugolix is a non-peptide GnRH receptor antagonist that competitively binds to pituitary GnRH receptors, thereby reducing the release of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH), leading to decreased serum concentrations of the ovarian sex hormones estradiol and progesterone and reduced bleeding associated with uterine fibroids. Estradiol acts by binding to nuclear receptors that are expressed in estrogen-responsive tissues. As a component of this tablet, the addition of exogenous estradiol may reduce the increase in bone resorption and resultant bone loss that can occur due to a decrease in circulating estrogen concentrations from relugolix alone. Progestins such as norethindrone act by binding to nuclear receptors that are expressed in progesterone-responsive tissues. As a component of this tablet, norethindrone may protect the uterus from the potential adverse endometrial effects of unopposed estrogen.

Dosage & Administration

Exclude pregnancy and discontinue hormonal contraceptives prior to this initiation. Orally one tablet once daily. In case of missed dose, need to take as soon as possible the same day and then resume regular dosing the next day at the usual time. If concomitant use of oral P-gp inhibitors is unavoidable, need to take this tablet at least 6 hours before taking the P-gp inhibitor.

Side Effects:-

Most common adverse reactions (incidence >3%) are: Hot flush, Hyperhidrosis or night sweats, Uterine bleeding, Alopecia, Decreased libido

Pregnancy & Lactation:-

Based on findings from animal studies and its mechanism of action, this may cause early pregnancy loss. Discontinue this tablet, if pregnancy occurs during treatment. There is no data on the presence of relugolix or its metabolites in human milk, the effects on the breastfed child or the effects on milk production. Relugolix was detected in milk in lactating rats. When a drug is present in animal milk, it is likely that the drug will be present in human milk.

Therapeutic Class:-

Gonadotropin-releasing hormone (GnRH) antagonist.
