Definition:A diaminopyridine that is 2,6-diaminopyridine substituted at position 3 by a phenylazo group. A local anesthetic that has topical analgesic effect on mucosa lining of the urinary tract. Its use is limited by problems with toxicity (primarily blood disorders) and potential carcinogenicity.
