An agonist is a biochemical that has the ability to bind to another molecule (called a cell receptor) and activate it to fulfill its function in the body. When the cell receptor is activated by the agonist, it causes a cell reaction that would be similar to a naturally provoked reaction. An agonist molecule is different from an antagonist molecule, because while the agonist causes an action, the antagonist prevents that action from happening.
Gonadotropin-releasing hormone agonists used to treat endometriosis are Leuprolide and Nafarelin acetate.
