Drugs for the overactive bladder: are there differences in persistence and compliance?

Karl-Erik Andersson


The overactive bladder (OAB) syndrome, characterized by urinary urgency with or without urgency urinary incontinence (UUI) and usually associated with increased daytime frequency and nocturia (1), is a common condition worldwide. Independent of the methodology used (telephone survey, postal survey) several epidemiologic studies in Europe, Canada, the United States, and Japan have shown the OAB syndrome to be present in 8.0% to 16.5% of adults, with similar rates between men and women (2,3).
