Venlafaxine Hydrochloride

Overview

Basic Info

SummaryVenlafaxine, a serotonin-norepinephrine reuptake inhibitor (SNRI), targeting the serotonin transporter (SERT-5) and norepinephrine transporter (NET), both of which are responsible for regulating the delicate balance of these neurotransmitters in the brain. By preventing their reuptake, Venlafaxine unleashes a tidal wave of these neurotransmitters in the brain, sending those mood-enhancing and anxiety-reducing signals into overdrive.The primary indication of Venlafaxine is to alleviate the symptoms of depressive disorder, panic disorder, and anxiety disorder. On December 28, 1993, the FDA approved Wyeth Corp's Venlafaxine . Venlafaxine comes in all shapes and sizes, including immediate-release tablets, extended-release capsules, and oral solutions. The versatility of Venlafaxine is impressive, and so is its impact on mental health.
