Question

The selective serotonin reuptake inhibitors (SSRIs), such as Prozac, Zoloft, and Paxil, differ from first- and second-generation antidepressants in that they:
A. affect levels of multiple neurotransmitters in the brain.
B. decrease levels of both serotonin and norepinephrine in the brain.
C. affect levels of only one neurotransmitter in the brain, norepinephrine.
D. affect levels of only one neurotransmitter in the brain, serotonin.

Answer 1

The selective serotonin reuptake inhibitors (SSRIs) differ from first- and second-generation antidepressants in that they affect levels of only one neurotransmitter in the brain, serotonin. It is an important chemical messenger.

Serotonin is a neurotransmitter that may have roles as a mood stabilizer and regulate sleep patterns.

Selective serotonin reuptake inhibitors (SSRIs) are antidepressants used for the treatment of depression.

SSRIs can inhibit the reuptake of serotonin by binding the transporter protein monoamine SERT and thus blocking the reuptake process.
