Fesoterodine (INN, used as the fumarate under the brand name Toviaz) is an antimuscarinic drug developed by Schwarz Pharma AG to treat overactive bladder syndrome (OAB).[1] It was approved by the European Medicines Agency in April 2007,[2] the US Food and Drug Administration on October 31, 2008 [3] and Health Canada on February 9, 2012.[4]

Fesoterodine is a prodrug. It is broken down into its active metabolite, 5-hydroxymethyl tolterodine, by plasma esterases.


Fesoterodine has the advantage of allowing more flexible dosage than other muscarinic antagonists.[5] Its tolerability and side effects are similar to other muscarinic antagonists and as a new drug seems unlikely to make great changes in practices of treatment for overactive bladder.[5]
