The action of MAO inhibitors occurs because the medication carries out which of the following actions?
a. stimulates production of MAO enzymes
b. blocks the enzyme from metabolizing monoamine neurotransmitters
c. alters the sensitivity of MAO receptors
d. is nonselective in its effects on monoamine neurotransmitters
B
MAOIs block the enzyme from metabolizing monoamine neurotransmitters. The enzyme's purpose is to metabolize the neurotransmitters into biologically inactive forms. The three specific neurotransmitters MAOIs block are norepinephrine, serotonin, and dopamine. The blocking of the enzyme results in an increased concentration of the neurotransmitters in neuronal cells.
