Estradiol enantate/algestone acetophenide

Estradiol enantate/algestone acetophenide (also known as E2-EN/DHPA) is a combination medication used in hormonal contraception. It contains two active ingredients: estradiol enantate (E2-EN), an estrogen, and algestone acetophenide (DHPA), a progestin. This combination is used primarily as a combined injectable contraceptive.

Components

• Estradiol enantate (E2-EN): A synthetic ester of estradiol, a naturally occurring estrogen.
• Algestone acetophenide (DHPA): A synthetic progestin used in hormonal contraception.

Mechanism of Action

The combination of estradiol enantate and algestone acetophenide works by inhibiting ovulation, altering the endometrium to prevent implantation, and thickening the cervical mucus to inhibit sperm penetration.
