Which medication is an example of a Tricyclic/Tetracyclic Antidepressant (TCA)?

The correct choice is indeed an example of a Tricyclic Antidepressant (TCA). Pamelor, also known as nortriptyline, is part of the TCA class, which is characterized by its three-ring chemical structure. These medications work by inhibiting the reuptake of certain neurotransmitters, primarily norepinephrine and serotonin, leading to an improvement in mood and relief from symptoms of depression.

Other medications listed serve different purposes or belong to different classes. For instance, Nardil is a monoamine oxidase inhibitor (MAOI) used to treat depression but is not a TCA. Effexor is an antidepressant that falls under the category of serotonin-norepinephrine reuptake inhibitors (SNRIs) and is utilized to treat major depressive disorder and anxiety disorders. Lastly, Zoloft is a selective serotonin reuptake inhibitor (SSRI), primarily indicated for depression and anxiety. Understanding the specific classifications of these medications is crucial for effectively treating various mental health conditions.
