Estradiol dibutyrate (EDBu), or estradiol dibutanoate, is an estrogen medication and an estrogen ester – specifically, a diester of estradiol – which is no longer used.^[1]^[2] It was a component of Triormon Depositum, a combination formulation of estradiol dibutyrate, testosterone caproate, and hydroxyprogesterone heptanoate which was developed in the 1950s.^[2]

Triormon depositum (estradiol dibutyrate 3, testosterone caprylate 50, and hydroxyprogesterone heptanoate 30 mg.), administered in castor oil-benzyl benzoate soln. or polyvinylpyrrolidone suspension to 21 women in climacteric, was followed by estradiol, pregnanediol, and 17-keto steroid urinary curves, most with a peak at the 4th day, and approaching starting values at the 8-10th day. The therapeutic efficacy of the drug was satisfactory.
