Pharmacology
- Indication
Norelgestromin is used for contraception and menopausal hormonal therapy. Norelgestromin may potentially be used in breast cancer treatment due to its inhibitory effect on estrone sulfatase . They convert sulfated steroid precursors to estrogen during pregnancy.

Learn More- Pharmacodynamics
Norelgestromin is used for contraception and menopausal hormonal therapy transdermally or in combination with ethinyl estradiol as a vaginal ring. Norelgestromin, in combination with ethinyl estradiol inhibits ovulation by suppressing gonadotropins.
- Mechanism of action
Norelgestromin inhibits estrone sulfatase, which converts sulfated steroid precursors to estrogen during pregnancy. Norgelgestromin/ethinylestradiol suppresses follicular development, induces changes to the endometrium, which decreases chances of implantation and thickens the cervical mucus, impeding sperm swimming into the uterus. It also has similar agonisting binding affinities as its parent compound, Norgestimate, for progesterone and estrogen receptors.
