DrugBankPrimary Accession Number: DB04839
TypeApproved, Investigational, Small Molecule
IndicationFor the palliative treatment of patients with advanced prostatic carcinoma.
Mechanism of ActionThe direct antiandrogenic effect of cyproterone is blockage of the binding of dihydrotestosterone to the specific receptors in the prostatic carcinoma cell. In addition, cyproterone exerts a negative feed-back on the hypothalamo-pituitary axis, by inhibiting the secretion of luteinizing hormone resulting in diminished production of testicular testosterone.
