Trinordiol is used to prevent pregnancy and treat hypogonadism in females, prevent menstruation, and treat symptoms of menopause. It contains the active ingredients ethinyl estradiol and levonorgestrel, which help prevent pregnancy. The drug comes in the form of tablets.
Trinordiol works to prevent ovulation by inhibiting the hormone gonadotropin. It also causes changes in the lining of the uterus and increases the viscosity of cervical mucus, which makes it difficult for sperm to enter the uterus, which leads to preventing pregnancy.
