Answer to Question 2

Antidepressant drugs fall into several categories, including tricyclics, selective serotonin reuptake inhibitors, monoamine oxidase inhibitors, and atypical antidepressants. The tricyclics (e.g., imipramine, trade name Tofranil) operate by blocking the transporter proteins that reabsorb serotonin, dopamine, and norepinephrine into the presynaptic neuron after their release. The selective serotonin reuptake inhibitors (SSRIs) are similar to tricyclics but specific to the neurotransmitter serotonin. The monoamine oxidase inhibitors (MAOIs) (e.g., phenelzine, trade name Nardil) block the enzyme monoamine oxidase (MAO), a presynaptic enzyme that metabolizes catecholamines and serotonin into inactive forms. The atypical antidepressants include everything other than the types just discussed (Horst & Preskorn, 1998). One example is bupropion (Wellbutrin), which inhibits reuptake of dopamine and to some extent norepinephrine but not serotonin. Although antidepressants vary in which neurotransmitter(s) they targetserotonin, dopamine, norepinephrine, or some combinationall appear to be nearly equal in their effectiveness (Montgomery et al., 2007).
