pharmachologic effect
Antiandrogenic non-steroidal drug. By binding to receptors that have an affinity for androgens, it suppresses the activity of androgens, as a result of which a regression of the prostate tumor is observed. Does not possess other types of endocrine activity.
Pharmacokinetics
After oral administration, it is well absorbed from the gastrointestinal tract. Food intake does not affect bioavailability.
Plasma protein binding is 96%. It is extensively metabolized in the liver by oxidation and formation of glucuronide conjugates.
It is excreted in the form of metabolites in the urine and bile in approximately equal proportions.
Cumulation of bicalutamide in the body is possible.

special instructions

Drug interactions

With the simultaneous use of bicalutamide with cyclosporine or calcium channel blockers, potentiation or development of undesirable reactions is possible.
It is theoretically possible to increase the concentration of bicalutamide in the blood plasma when it is used simultaneously with inhibitors of microsomal liver enzymes, which may be accompanied by an increase in the incidence of adverse reactions.
In vitro studies have shown that bicalutamide can displace the coumarin anticoagulant warfarin from plasma protein binding sites.
