- Phenazopyridine is a medication that has a local anesthetic effect on the inner lining of the lower urinary tract.
- The precise mechanism of action of phenazopyridine is unknown.
- By having an anesthetic effect on the mucosa of urinary tract, phenazopyridine numbs the mucosa of the urinary tract, thus reducing the sensitivity for pain and irritation.
