Summary

This trial is testing whether sildenafil can improve urinary incontinence by improving blood flow and muscle mass in the pelvic floor.

Who is the study for?
This trial is for postmenopausal women aged 50-80 with stress or mixed urinary incontinence, experiencing at least three episodes a week. Participants should be able to follow the study procedures and provide consent. Excluded are those with significant health issues like heart or liver disease, active cancer, untreated endocrine diseases, high BMI (>40), certain infections (HIV/Hepatitis), or on conflicting medications.
What is being tested?
The trial is testing Sildenafil's effectiveness against urinary incontinence by improving pelvic floor muscle function. Women will either receive Sildenafil or a placebo to see if there's an improvement in their symptoms compared to those not receiving the drug.
What are the potential side effects?
Sildenafil may cause side effects such as headaches, flushing, indigestion, nasal congestion, dizziness, and visual disturbances. It can also potentially affect blood pressure and interact with other medications.
