Neurotransmitters Agonists and Antagonists 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.
Neurotransmitters -excitatory Acetylcholine Norepinephrine Glutamate
Neurotransmitters- inhibitory GABA
Neurotransmitters-both Dopamine Serotonin Endorphin
