A serotonin-norepinephrine reuptake inhibitor (SNRI) antidepressant that blocks reuptake of both serotonin and norepinephrine, used to treat depression, anxiety disorders, and chronic pain conditions.
Developed by Wyeth (now Pfizer) in the 1990s, the name derives from its chemical structure as a phenethylamine derivative. The '-ine' suffix is standard pharmaceutical nomenclature for nitrogen-containing compounds.
Venlafaxine is like getting two antidepressants in one pill - it affects both serotonin (mood) and norepinephrine (energy/focus) pathways. At low doses it acts mainly like an SSRI, but at higher doses the norepinephrine effects kick in, making it particularly useful for patients with both depression and chronic pain.
