medroxyprogesterone A synthetic derivative of progesterone administered as an acetate salt (medroxyprogesterone acetate) with antiestrogenic activity. As a do all progestins, medroxyprogesterone binds to and activates nuclear receptors which subsequently bind to and activate target genes for transcription. As an antiestrogen, this agent may inhibit the growth-stimulating effects of estrogen on estrogen-sensitive tumor cells. Check for active clinical trials or closed clinical trials using this agent.
