what is the difference between inhibitors and exhibitors?
Agonist makes more of a neurotransmitter or makes it more available. Cocaine agonizes dopamine. Prozac agonizes serotonin by slowing reuptake.
Antagonist blocks or makes a neurotransmitter less available. Naltrexone is used to treat opioid addiction by blocking the receptors for the drug. Caffeine antagonizes GABA (an NT that “relaxes” us), which is why drinking coffee can make you jittery.
