Estradiol valerate/norethisterone enantate (EV/NETE), sold under the brand name Mesigyna among others, is a form of combined injectable birth control which is used to prevent pregnancy in women.[1][2][3][4] It contains estradiol valerate (EV), an estrogen, and norethisterone enantate (NETE), a progestin.[1][2][3] The medication is given once a month by injection into muscle.[1][2][3]
EV/NETE is approved for use in at least 36 countries, and is the most widely used combined injectable contraceptive.[5][3] It is available widely throughout Latin America, in a few Asian and African countries, and in Turkey.[6][7][8]
Medical uses
[edit]EV/NETE is used as a combined injectable contraceptive to prevent pregnancy in women.[1][2][3] It is given by intramuscular injection once a month.[1][2][3]
Available forms
[edit]EV/NETE is available in the form of an oil solution containing 5 mg estradiol valerate (EV) and 50 mg norethisterone enantate (NETE).[5][1][2][3]
Pharmacology
[edit]Pharmacodynamics
[edit]
EV/NETE is a combination of EV, an estrogen, and NETE, a progestogen with weak androgenic activity.
Through its progestogenic activity, NETE has potent antigonadotropic effects and can inhibit fertility and suppress sex hormone levels. A single intramuscular injection of EV/NETE has been found to strongly suppress testosterone levels in men.[9] Levels of testosterone decreased from ~503 ng/dL at baseline to ~30 ng/dL at the lowest point (–94%) which occurred at day 7 post-injection.[9]
Pharmacokinetics
[edit]Peak levels of estradiol after an intramuscular injection of EV/NETE (5 mg/50 mg) are reached within 2 days and range from 232 to 428 pg/mL.[4][1]
History
[edit]EV/NETE, along with estradiol cypionate/medroxyprogesterone acetate (EC/MPA; code name HRP-112), was developed by the World Health Organization.[5][10] Both EV/NETE and EC/MPA became available in 1993.[11]
Society and culture
[edit]Generic names
[edit]EV/NETE is also known by its former developmental code name HRP-102.[12]
