Estradiol valerate/norethisterone enantate
(Redirected from Chinese Injectable Number 3)
Estradiol valerate/norethisterone enantate is a combination medication used in hormonal contraception and hormone replacement therapy. It contains two active ingredients: estradiol valerate, an estrogen, and norethisterone enantate, a progestin. This combination is designed to provide effective contraception and manage symptoms associated with menopause.
Medical Uses[edit | edit source]
Estradiol valerate/norethisterone enantate is primarily used for:
- Contraception: It prevents ovulation and creates changes in the cervical mucus and endometrium that reduce the likelihood of fertilization and implantation.
- Hormone replacement therapy: It alleviates symptoms of menopause such as hot flashes, vaginal atrophy, and osteoporosis.
Mechanism of Action[edit | edit source]
The combination works by:
- Estradiol valerate: Mimics the natural estrogen in the body, helping to regulate the menstrual cycle and maintain bone density.
- Norethisterone enantate: Acts as a progestin, preventing the endometrial hyperplasia that can occur with estrogen-only therapy and providing contraceptive effects.
Administration[edit | edit source]
Estradiol valerate/norethisterone enantate is typically administered via intramuscular injection. The frequency of administration can vary based on the specific formulation and the intended use, such as monthly for contraception.
