Stress urinary incontinence (SUI) is the most common form of urinary incontinence and occurs more frequently in women than in men. Duloxetine is a balanced dual serotonin (5-HT) and norepinephrine (NE) reuptake inhibitor and shows no relevant binding affinity for histaminergic, dopaminergic, cholinergic, and adrenergic receptors. The efficacy of duloxetine in SUI is based on the inhibition of the presynaptic reuptake of 5-HT and NE in Onuf's nucleus of the sacral spinal cord, whereby it may increase the concentration of 5-HT and NE in the synaptic cleft. The effectiveness of duloxetine was studied in a cat model of acetic acid-induced bladder irritation. The results showed that in cats with previous irritated bladder function, there was a dosage-dependent improvement of bladder capacity and periurethral electromyography (EMG) activity. In women with SUI, it is assumed that the clinical efficacy of duloxetine is based on stronger urethral contraction and persistent sphincter tone during the storage phase. In clinical trials in women with SUI, duloxetine has demonstrated efficacy in reducing incontinence episodes and increasing quality of life. Nausea was the most common adverse event and the main cause for discontinuation. In summary, duloxetine appears to be a promising new option for the treatment of SUI.

Inhibitors of serotonin (5-HT) and/or noradrenaline (NA) reuptake have been developed for pharmacological treatment of major depressive disorder. Insights in the role of 5-HT and NA in the neurological control of the lower urinary tract have also led to their application in common urological conditions such as stress urinary incontinence (SUI), nocturnal enuresis and ejaculatory disorders. The European approval of the 5-HT and NA reuptake inhibitor (SNRI) duloxetine for treatment of SUI underlines the importance of a new approach in SUI, but has also given rise to questions about the safety of antidepressants in urology. This paper reviews the safety of 5-HT and NA reuptake inhibitors in their on- and off-label use in urology. A systematic Medline search was performed for randomised controlled trials, meta-analyses and practice guidelines dealing with antidepressants in urology. The safety profiles of the drugs in the urological population were compared with data from psychiatric populations. Tricyclic antidepressants are associated with serious cardiovascular side effects. In addition, anticholinergic and antihistaminic side effects are common. Although recently questions have been raised regarding the cardiovascular safety profile of venlafaxine, most selective 5-HT reuptake inhibitors and SNRI have not been associated with serious cardiovascular effects. Their most common side effect is nausea. However, nausea tends to be mild and, importantly, transient. Patient counselling about side effects and up-titrating doses may be useful strategies for minimising discomfort and withdrawals.

This manuscript reviews the pharmacodynamics and pharmacokinetics of duloxetine and its efficacy and safety in women with stress urinary incontinence. Duloxetine is a selective inhibitor of neuronal serotonin and norepinephrine uptake which increases urethral striated muscle activity and bladder capacity. Duloxetine is readily absorbed and extensively metabolized; cytochrome P450 1A2 (CYP1A2) inhibiting drugs can markedly increase duloxetine exposure. The clinical efficacy of duloxetine has consistently been demonstrated in several randomized, double-blind studies in women with moderate-to-severe stress urinary incontinence, but the additional benefit relative to placebo was moderate. Duloxetine treatment is frequently associated with adverse events such as nausea, dry mouth, fatigue, insomnia and constipation, but serious adverse events are rare. Therefore, duloxetine appears suitable for the treatment of stress urinary incontinence.
