What type of contraception is Orthonovum classified as?

Orthonovum is classified as estrogen-based contraception. It is a combination oral contraceptive that includes both estrogen and progestin hormones, working synergistically to prevent ovulation, thicken cervical mucus, and alter the uterine lining to reduce the likelihood of pregnancy. The presence of estrogen is crucial for the regulation of the menstrual cycle and contributes to the contraceptive effectiveness of the medication.

Combination oral contraceptives like Orthonovum are well-established in clinical practice and are often prescribed for their ability to manage cycle-related issues as well as providing effective contraception. Understanding the role of estrogen in these contraceptives helps in recognizing their broader implications for health, including potential benefits and risks associated with hormone replacement therapy in various patient populations.
