Active ingredient

Estramustine is a chemical compound of oestradiol and nitrogen mustard. It is effective in the treatment of advanced prostatic carcinoma. Estramustine has a dual mode of action. The intact molecule acts as an anti-miotic agent; after hydrolysis of the carbamate ester, the metabolites act to bridge the released oestrogens and exert an anti-gonadotrophic effect.
