What is Norgestimate?
Norgestimate is a synthetic progestin, a type of hormone used in various forms of hormonal contraception and hormone replacement therapy. It is often combined with an estrogen, such as ethinyl estradiol, in oral contraceptive pills. This combination helps regulate the menstrual cycle, prevent ovulation, and provide contraception.
Mechanism of Action
Norgestimate works primarily by inhibiting ovulation. It does this by suppressing the release of gonadotropins, specifically luteinizing hormone (LH) and follicle-stimulating hormone (FSH), from the pituitary gland. Additionally, norgestimate increases the viscosity of cervical mucus, making it difficult for sperm to enter the uterus, and alters the endometrial lining to prevent implantation.Uses in Gynecology
