Bicalutamide is an antitumor agent; it is a racemic mixture with nonsteroidal antiandrogenic activity of predominantly (R)-enantiomer; it has no other endocrine activity.
Bicalutamide binds to androgen receptors on the surface of target organ cells, suppressing the stimulating effects of androgens without activating gene expression. As a result there is regression of prostate malignancies.
In some patients discontinuation of bicalutamide may lead to development of clinical syndrome “withdrawal” of antiandrogens.
Indications
Prostate cancer:
– treatment of advanced prostate cancer in combination with a gonadotropin-releasing hormone analogue (GnRH analogue) or surgical castration;
– monotherapy or adjuvant therapy in combination with radical prostatectomy or radiotherapy for locally advanced prostate cancer (T3-T4, any N, M0; T1-T2, N+, M0);
– treatment of locally advanced, non-metastatic prostate cancer in cases where surgical castration or other medical interventions are unacceptable or not applicable.
Pharmacological effect
Bicalutamide is an antitumor agent, it is a racemic mixture with non-steroidal antiandrogenic activity, predominantly of the (R)-enantiomer, and has no other endocrine activity.
Bicalutamide binds to androgen receptors on the surface of cells in target organs, suppresses the stimulating effects of androgens without activating gene expression. As a result, regression of malignant neoplasms of the prostate gland occurs.
In some patients, discontinuation of bicalutamide may lead to the development of clinical antiandrogen withdrawal syndrome.
