Estramustine Phosphate Sodium
C23H30ClNNaO6P
• Estramustine phosphate sodium, a complex of 17 ?-estradiol and nornitrogen mustard, is an antimicrotubule antineoplastic agent.

Most studies were conducted before the realization that administration of estramustine with milk or calcium-containing products substantially impairs absorption of the drug; therefore, overall clinical efficacy (i.e., objective response) of estramustine may have been underestimated.
