Competitive antagonist

A competitive antagonist is a receptor antagonist that binds to a receptor but fails to activate it. If an agonist competes with a competitive antagonist for the same binding site on the same receptor, the agonist molecules can be displaced from the binding site, resulting in a lower frequency of receptor activation.
