摘要
Fesoterodine is a prodrug of 5-hydroxymethyl tolterodine, which is the main active metabolite of tolterodine. Taking both gives duplicate antimuscarinic therapy and no added benefit. Anticholinergic adverse effects such as dry mouth, constipation, urinary retention and QT effects become more likely.
