Desvenlafaxine is a synthetic form of the isolated major active metabolite of venlafaxine, and is categorized as a serotonin-norepinephrine reuptake inhibitor (SNRI). When most normal metabolizers take venlafaxine, approximately 70% of the dose is metabolized into desvenlafaxine, so the effects of the two drugs are expected to be very similar. [18]

Serotonin–norepinephrine reuptake inhibitors (SNRIs) such as venlafaxine (Effexor), its active metabolite desvenlafaxine (Pristiq), and duloxetine (Cymbalta) prevent the reuptake of both serotonin and norepinephrine, however their efficacy appears to be only marginally greater than the SSRIs. [218]
