Darifenacin (DFN)

Darifenacin is a medication used to treat urinary incontinence. Darifenacin works by blocking the M3 muscarinic acetylcholine receptor, which is primarily responsible for bladder muscle contractions. It thereby decreases the urgency to urinate. Darifenacin is indicated for the treatment of overactive bladder with symptoms of urge urinary incontinence, urgency and frequency in adults.It is not known whether this selectivity for the M3 receptor translates into any clinical advantage when treating symptoms of overactive bladder syndrome. It should not be used in people with urinary retention. Anticholinergic agents, such as Enablex, may also produce constipation and blurred vision. Heat prostration (due to decreased sweating) can occur when anticholinergics such as Enablex are used in a hot environment.
