Abstract
Objectives: To evaluate the efficacy and safety of duloxetine in community-dwelling women ≥65 years with stress urinary
incontinence (SUI) or stress-predominant mixed urinary incontinence (S-MUI) versus placebo.
Methods: Patients were randomly assigned for 12 weeks to placebo (N = 134) or duloxetine (N = 131) (20 mg twice daily [BID]
for 2 weeks and 40 mg BID for an additional 10 weeks), followed by a double-blind 4-week dose de-escalation/discontinuation
phase. The primary efficacy variable was the percent change in incontinence episode frequency (IEF) from baseline to endpoint.
Other variables included absolute IEF change, responder rate, changes in mean time between voids (MTBV), weekly continence
pad usage, the impact of treatment on quality of life, patient’s global impression of improvement (PGI-I), and changes in
depression and cognition.
Results: Duloxetine-treated patients had a significantly greater decrease from baseline to endpoint in mean IEF/week than
placebo-treated patients (-52.47% vs. -36.70%, P < 0.001). The IEF responder rate (≥50% reduction in IEF/week) was 57.1%
in the duloxetine group and 35.2% in the placebo group (P < 0.001). Significant benefits of duloxetine were also demonstrated
for weekly continence pad usage (P = 0.011), MTBV (P < 0.001), incontinence quality of life questionnaire (I-QOL) scores
(P < 0.001), and PGI-I ratings (P < 0.001). Patients with depressive symptoms and cognitive impairments were few and changes
were insignificant. The proportion of patients with ≥1 treatment-emergent adverse event (TEAE) was similar with both treatments,
but dry mouth, fatigue, constipation, and hyperhidrosis were significantly more common in women taking duloxetine.
Conclusions: Duloxetine is a safe and effective treatment for elderly women with symptoms of SUI or S-MUI.
