OBJECTIVE
The safety and tolerability of duloxetine for major depressive disorder (MDD), generalized anxiety disorder (GAD), diabetic peripheral neuropathic pain (DPNP), fibromyalgia, and lower urinary tract disorders (LUTD) (including female stress urinary incontinence [SUI] and other LUTDs) has been established in individual clinical studies. The objective of this manuscript is to characterize the overall safety profile of duloxetine, regardless of indication, based on data from the duloxetine exposures integrated safety database.
METHODS
The duloxetine exposures integrated safety database was examined using pooled data from 23,983 patients randomized to receive duloxetine in 64 studies for MDD, GAD, DPNP, fibromyalgia, or LUTDs. Evaluated aspects of drug safety included treatment-emergent adverse events (TEAEs), adverse events leading to discontinuation, serious adverse events (SAEs), clinical laboratory tests, vital signs, and electrocardiograms.
RESULTS
Common TEAEs included nausea, headache, dry mouth, insomnia, constipation, dizziness, fatigue, somnolence, diarrhea, and hyperhidrosis. Most TEAEs emerged early; the majority were mild to moderate in severity, and did not worsen. Overall, discontinuation rates due to AEs were 20.0%. SAEs occurred at a rate of 3.5% and no single event was predominant. Mean pulse increased by < 2 beats per minute. Mean increases in systolic and diastolic blood pressure were < 1 mmHg. Mean alanine transaminase and aspartate transaminase values increased by < 2 U/L.
CONCLUSIONS
The safety profile for the molecule from the overall duloxetine exposures integrated safety database suggests that benign and common pharmacologic side effects occur with duloxetine treatment. Because these pooled analyses do not allow for statistical comparison to placebo or active comparator, and include data from five different studied indications, these data do not suggest causality for AEs, nor are they necessarily generalizable to each disease stated studied.
