Estradiol dienanthate (EDE), sold under the brand names Climacteron among others, is a long-acting estrogen medication which was previously used in menopausal hormone therapy for women and to suppress lactation in women.[1][2][3][4] It was formulated in combination with estradiol benzoate (EB), a short-acting estrogen, and testosterone enanthate benzilic acid hydrazone (TEBH), a long-acting androgen/anabolic steroid.[2][3][4] EDE has not been made available for medical use alone.[5] The medication, in combination with EB and TEBH, was given by injection into muscle once or at regular intervals, for instance once every 6 weeks.[6][7][8]

Side effects of EDE include breast tenderness, breast enlargement, nausea, headache, and fluid retention.[9] EDE is an estrogen and hence is an agonist of the estrogen receptor, the biological target of estrogens like estradiol.[10][11] It is an estrogen ester and a prodrug of estradiol in the body.[11][10] Because of this, it is considered to be a natural and bioidentical form of estrogen.[11]

EDE was first described by 1959.[12][13] It was previously available in Canada and Germany but was discontinued by 2005.[14][15][16] The medication is no longer available in any form.[5]

Springer Science & Business Media. p. 261. ISBN 978-3-642-60107-1. Natural estrogens considered here include: [...] Esters of 17β-estradiol, such as estradiol valerate, estradiol benzoate and estradiol cypionate. Esterification aims at either better absorption after oral administration or a sustained release from the depot after intramuscular administration. During absorption, the esters are cleaved by endogenous esterases and the pharmacologically active 17β-estradiol is released; therefore, the esters are considered as natural estrogens.
