You will have to ask either SilverFlight or Hey1234. I am just following their lead. But accroding to Hey1234 antagonist does not in fact mean villain. It really stands for a substance who/which interferes with or inhibits the physiological action of another. We only say "Antagonist" in the articles because it's more formal.
