An antagonist is a substance that blocks the effects of something else. In medicine, an example would be Benadryl (diphenhydramine, usually used to relieve allergy symptoms) is a histamine antagonist. So when the body releases a large amount of histamine into your bloodstream (like during an allergic reaction), we can take Benadryl. The Benadryl will bind to the histamine receptors in the body and block the histamine from attaching and causing an allergic reaction.

Narcan (naloxone) is an opioid antagonist, which can reverse an opioid overdose.
