List of Progestogens Available in the United States

Progestogens, also known as progestins or gestogens, are a class of hormones that play an essential role in the menstrual cycle, pregnancy, and embryogenesis of humans and other species. They are synthetic versions of the naturally occurring hormone progesterone. In the United States, progestogens are available in various forms and are used for a range of medical purposes, including contraception, hormone replacement therapy (HRT), and the treatment of menstrual disorders and endometriosis. This article provides a comprehensive list of progestogens available in the United States, categorized by their type and primary use.

Types of Progestogens

Progestogens can be classified into several types based on their source and chemical structure:

Natural Progesterone

Natural progesterone is identical to the hormone produced by the ovaries. It is often used in hormone replacement therapy for menopausal symptoms and in fertility treatments.

• Progesterone (Prometrium, Crinone)

Synthetic Progestins

Synthetic progestins are chemically derived and designed to mimic the action of natural progesterone. They are used in various forms of contraception and to treat hormonal imbalances.

• Medroxyprogesterone acetate (Provera, Depo-Provera)
• Norethindrone (Aygestin, Nor-QD)
• Levonorgestrel (Plan B, Mirena)
• Norgestimate (Ortho Tri-Cyclen, Sprintec)
• Drospirenone (Yasmin, Yaz)

Uses of Progestogens

Progestogens are used for a variety of medical conditions and purposes, including:

• Contraception: Progestogens are a key component in many forms of contraceptive methods, including birth control pills, intrauterine devices (IUDs), and injectable contraceptives.
• Hormone Replacement Therapy (HRT): For menopausal symptoms, progestogens are used in combination with estrogen to reduce the risk of endometrial cancer associated with estrogen-only HRT.
• Treatment of Menstrual Disorders: Progestogens can be used to regulate the menstrual cycle, treat amenorrhea (absence of menstruation), and reduce menstrual cramps.
• Treatment of Endometriosis: Progestogens can help manage the pain and reduce the progression of endometriosis.
