Estradiol/levonorgestrel
Estradiol/levonorgestrel (pronunciation: es-tra-DYE-ol/LEE-vo-nor-jest-rel) is a combination medication used in hormone replacement therapy (HRT) and as a contraceptive.
Etymology
The term Estradiol is derived from estra-, a prefix referring to estrus, and -diol, a chemical term denoting a type of alcohol. Levonorgestrel is a synthetic progestin and is not derived from a natural compound, hence its etymology is not known.
Usage
Estradiol is a form of estrogen, a female sex hormone produced by the ovaries. Levonorgestrel is a form of progestin, a female hormone important for regulating ovulation and menstruation. When combined, they are used to prevent pregnancy (as a contraceptive) or to treat symptoms of menopause (as part of HRT).
