Pharmacological action

Flutamide is a nonsteroidal drug with anti-androgenic action. The mechanism of action involves the inhibition of androgen capture and/or inhibition of androgen binding in cell nuclei of tissues-targets. Its ability to inhibit the action of testosterone at the cellular level is to complement the medical “castration” caused by agonists of luteinizing hormone — releasing hormone (LHRH). Target organs of pharmacological action of flutamide are the prostate and seminal vesicles. Flutamid does not possess estrogenic, anti-estrogenic and progestogenic antigestagen activity.
