Estramustine (Emcyt, Estracit) is a chemotherapy agent used to treat prostate cancer. It is a derivative of estrogen (specifically, estradiol) with an nitrogen mustard-carbamate ester moiety that makes it a alkylating antineoplastic agent similar to mechlorethamine, with estrogen-induced specificity.

Estramustine is marketed in the United States by Pharmacia (now a subsidiary of Pfizer)

Clinical uses

Estramustine is indicated for the palliative treatment of metastatic and/or progressive carcinoma of the prostate.
