SSRIs improve depression by which action? SSRIs:
a. destroy increased amounts of serotonin.
b. block muscarinic and 1 norepinephrine receptors.
c. make more serotonin available at the synaptic gap.
d. increase production of acetylcholine and dopamine.
C
Depression is thought to be related to lowered availability of the neurotransmitter serotonin. SSRIs act by blocking reuptake of serotonin, leaving a higher concentration available at the synaptic cleft. SSRIs prevent destruction of serotonin. SSRIs have little or no effect on acetylcholine and dopamine production. SSRIs do not produce muscarinic or 1 norepinephrine blockade.
