Darifenacin (trade name Enablex in United States and Canada, Emselex in the European Union) is a medication used to treat urinary incontinence due to an overactive bladder.[1][2][3] It was discovered by scientists at the Pfizer research site in Sandwich, UK under the identifier UK-88,525 and used to be marketed by Novartis. In 2010, the US rights were sold to Warner Chilcott for US$400 million.
