Agonist


A drug that binds to a receptor of a cell and triggers a response by the cell. An agonist often mimics the action of a naturally occurring substance.

An agonist produces an action. It is the opposite of an antagonist which acts against and blocks an action.

Agonists and antagonists are key agents in the chemistry of the human body and important players today in pharmacology.
