Which term describes a drug that binds to a receptor but does not produce a response?

Explanation:
When a substance binds to a receptor but does not trigger the receptor's signaling, it blocks activation by other ligands and is an antagonist. It has little to no intrinsic activity, so by itself it does not produce a downstream response. This contrasts with a full agonist, which produces the full response; a partial agonist, which produces a partial response; and an inverse agonist, which reduces baseline receptor activity. So the term for a drug that binds a receptor without producing a response is antagonist.
