Which antidepressant is known for its dual mechanism of inhibiting both serotonin and norepinephrine reuptake, but lacks the significant alpha-blocking and anticholinergic effects of TCAs?
Show answer and explanation
Correct answer: Venlafaxine
Venlafaxine is a Serotonin-Norepinephrine Reuptake Inhibitor (SNRI). At lower doses, it primarily affects serotonin, but at higher doses, it also inhibits the reuptake of norepinephrine, providing a 'dual' effect without the side-effect profile of older tricyclic agents.
