The aim was to assess the pharmacokinetics of tolterodine released from vaginal rings and of its active metabolite 5-hydroxymethyl tolterodine (5-HMT) compared to the respective pharmacokinetics resulting from oral administration of extended-release tolterodine in healthy, postmenopausal women. In this single-center, open-label trial, subjects received 4 treatments in a fixed sequence fasted oral extended-release tolterodine 2.74 mg/d (reference, 5 days), single vaginal rings; tolterodine releasing rates 0.95 mg/d (test 1, 13 days),
