Urinary incontinence is a disease able to decrease the quality of life of affected women. It shows a prevalence of about 35% among adult women. Pharmacological treatment can be used when pelvic floor muscle training has failed or when it could be better to postpone or avoid surgery. Duloxetine, a selective serotonin and noradrenaline reuptake inhibitor (SNRI), can act effectively in treating stress urinary incontinence.
