Bicalutamide is an oral non-steroidal anti-androgen for prostate cancer. It is a racemic mixture consisting of equal proportions of enantiomers (R)-bicalutamide and (S)-bicalutamide. Bicalutamide binds to the androgen receptor.


For treatment (together with surgery or LHRH analogue) of advanced prostatic cancer.

Mechanism of Action

Bicalutamide competes with androgen for the binding of androgen receptors, consequently blocking the action of androgens of adrenal and testicular origin which stimulate the growth of normal and malignant prostatic tissue.


Bicalutamide is well-absorbed following oral administration, although the absolute bioavailability is unknown.
Bicalutamide undergoes stereo specific metabolism. The S (inactive) isomer is metabolized primarily by glucuronidation. The R (active) isomer also undergoes glucuronidation but is predominantly oxidized to an inactive metabolite followed by glucuronidation.
