DRUG CLASS AND MECHANISM:
- Azelaic acid is a topical (applied to the skin) medication used for treating acne. Its exact mechanism of action is unknown. Azelaic acid may work as an antibacterial agent that blocks protein synthesis and therefore growth of Propionibacterium acnes and other bacteria on the surface of the skin that are associated with the development of acne. It may also inhibit follicular keratinization, which prevents development of acne lesions. The FDA approved azelaic acid in September 1995.
