Vue d’ensemble

Estramustine phosphate sodium (EMP, Emcyt, Estracyt) is an antitumour drug with a unique dual mode of action. Estrone and estradiol, products of the metabolism of estramustine phosphate sodium, have shown antigonadotrophic activity resulting in reduced testosterone levels. Estramustine(the cytotoxic metabolite produced by dephosphorylation of estramustine phosphate sodium) is an antiprostatic tumor drug with antimicrotubule effects.

Note
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
