Phenazopyridine (hydrochloride)

Phenazopyridine is an azo dye with analgesic properties. It decreases the bladder distension-induced firing rate of afferent bladder Agamma-fibers, but not C-fibers, in anesthetized rats when administered at a doses of 0.3, 1, and 3 mg/kg. Formulations containing phenazopyridine have been used as analgesics in the treatment of urinary tract infections.Formal Name: 3-(2-phenyldiazenyl)-2,6-pyridinediamine, monohydrochloride.
