New combo pill shows promise for bladder control in women
NCT ID NCT07312955
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether adding tadalafil (a drug for erectile dysfunction and enlarged prostate) to solifenacin (a standard overactive bladder drug) works better than solifenacin alone for women with overactive bladder. 80 women aged 18 to 60 with symptoms for over 6 months took either both drugs or just solifenacin for 3 months. The goal was to see if the combination improved bladder symptoms like urgency and frequency more effectively.
