List of progestogen esters

(Redirected from Norethisterone ester)

This is a list of progestogen esters, or esters of progestogens.[1][2][3][4]

Norethisterone acetate, a widely used progestogen ester and prodrug of norethisterone.
Medroxyprogesterone acetate, a progestogen ester that does not act as a prodrug.

Unlike the case of testosterone and estradiol, progesterone cannot be esterified as it lacks hydroxyl groups, so all progestogen esters, with the exception of esters of 17α-hydroxyprogesterone like hydroxyprogesterone caproate, are esters of progestins (synthetic progestogens) and are non-bioidentical. In addition, whereas all androgen and estrogen esters are prodrugs of the parent compound, only some and not all progestogen esters act as prodrugs. Esters of 17α-hydroxyprogesterone and 19-norprogesterone derivatives like hydroxyprogesterone caproate, medroxyprogesterone acetate, and nomegestrol acetate are active themselves and are not prodrugs, whereas esters of 19-nortestosterone derivatives like norethisterone acetate and norethisterone enanthate are not active themselves and are prodrugs.
