The main goal of our present experiments was to determine whether a 14-day administration of solifenacin (0.03 mg/kg/day), mirabegron (1 mg/kg/day), or duloxetine (1 mg/kg/day) would reverse detrusor overactivity and depression-like signs in female Wistar rats subjected to corticosterone treatment. Surgical procedures, cystometric studies, biochemical analyses, and the forced swim test were performed according to published literature. After 14 days of exposure to corticosterone (20 mg/kg, subcutaneously), the tested animals presented symptoms of depression, detrusor overactivity, inflammation, and disturbances in neurotrophic factors. The obtained results demonstrated that solifenacin and mirabegron act mainly via peripheral pathways in OAB, whereas the central pathways are responsible for the effects of duloxetine. 72 h after discontinuation of duloxetine treatment, positive changes in the corticosterone-induced depression, detrusor overactivity, and inflammation were observed. Duloxetine seems to have a potential to become a new ...
