A patient with major depressive disorder is prescribed an antidepressant that primarily inhibits the reuptake of serotonin and, to a lesser extent, norepinephrine. This drug belongs to which class of antidepressants?

A Selective serotonin reuptake inhibitors (SSRIs)
B Serotonin-norepinephrine reuptake inhibitors (SNRIs)
C Tricyclic antidepressants (TCAs)
D Monoamine oxidase inhibitors (MAOIs)

✓ Correct Answer: Option B

SNRIs, such as venlafaxine or duloxetine, selectively inhibit the reuptake of both serotonin and norepinephrine. SSRIs primarily inhibit serotonin reuptake, while TCAs and MAOIs have broader or different mechanisms.
