Hormone Receptor Antagonism

Meaning

Hormone Receptor Antagonism is a fundamental pharmacological mechanism where a specific compound, known as an antagonist, binds to a hormone receptor site without activating it, thereby blocking the binding and subsequent action of the natural, endogenous hormone. This action effectively prevents the hormone from eliciting its biological signal in the target cell, leading to a functional nullification of the hormone’s effect. Clinically, antagonists are invaluable therapeutic tools used to counteract the effects of excessive hormone activity or to inhibit the growth of hormone-sensitive tissues, such as in the treatment of certain cancers or endocrine disorders.
