Description:
Mechanism of Action: Azelaic acid is a naturally occurring aliphatic dicarboxylic acid that exhibits antiproliferative and antibacterial properties. Its exact mechanism of action is unknown, but studies show that it inhibits the proliferation of keratocytes and normalises the disturbed terminal epidermal differentiation processes in acne. Additionally, azelaic acid inhibits protein synthesis, thereby preventing the growth of susceptible organisms on the skin surface.
Onset: Within 4 weeks (cream).
Pharmacokinetics:
Absorption: Absorbed systemically (approx 4%).
Metabolism: Metabolised via β-oxidation into short-chained dicarboxylic acids.
Excretion: Via urine (as unchanged drug). Elimination half-life: 12 hours.
