An agonist is a molecule capable of binding to and functionally activating a target. The target is typically a metabotropic and/or ionotropic receptor. An antagonist is a molecule that binds to a target and prevents other molecules (e.g., agonists) from binding. Antagonists have no effect on receptor activity.
