binding. A drug causes these sodium channels to close entirely. What could the drug be
classified as? - ANSWER--inverse agonist
A natural ligand (neurotransmitter) causes sodium leak channels to open, allowing more
sodium to pass through than the small amount that occurs without neurotransmitter
binding. A drug causes these sodium channels to open to a level greater than when no
neurotransmitter is present but not as high as when the neurotransmitter is present.
What could the drug be classified as? - ANSWER--partial agonist
