Overview

What is Duloxetine?

Duloxetine (Cymbalta) is a serotonin-norepinephrine reuptake inhibitor (SNRI) FDA-approved for major depression, generalized anxiety disorder, fibromyalgia, diabetic peripheral neuropathy, and chronic musculoskeletal pain.

Key Benefits

Treats depression and anxiety, reduces chronic neuropathic and musculoskeletal pain, improves stress urinary incontinence (Europe). Dual NE/5-HT effect addresses both mood and pain modulation.

Mechanism of Action

Inhibits the serotonin transporter (SERT) and norepinephrine transporter (NET) with relatively balanced affinity, increasing synaptic 5-HT and NE in cortical, limbic, and descending pain-modulatory circuits.
