Desvenlafaxine is a synthetic form of the isolated major active metabolite of Venlafaxine, and is categorized as a Serotonin-Norepinephrine Reuptake Inhibitor (SNRI). It works by blocking the transporter reuptake protein for key neurotransmitters affecting mood, thereby leaving more active neurotransmitters in the synapse. The neurotransmitters affected are Serotonin (5-hydroxytryptamine) and Norepinephrine (Noradrenaline). It is approximately 10 times more potent at inhibiting Serotonin uptake than Norepinephrine uptake.The exact mechanism of the antidepressive action of Desvenlafaxine is unknown, but is thought to be related to the potentiation of Serotonin and Norepinephrine in the central nervous system, through inhibition of their reuptake. Non-clinical studies have shown that Desvenlafaxine is a potent Serotonin and Norepinephrine Reuptake Inhibitor (SNRI).
