“May all be happy, may all be healed, may all be at peace and may no one ever suffer."
The mechanism of action by which Amlexanox accelerates healing of aphthous ulcers is unknown. In vitro studies have demonstrated Amlexanox to be a potent inhibitor of the formation and release of inflammatory mediators (histamine and leukotrienes) from mast cells, neutrophils and mononuclear cells. Given orally to animals, Amlexanox has demonstrated anti-allergic and anti-inflammatory activities and has been shown to suppress both immediate and delayed-type hypersensitivity reactions. The relevance of these activities of Amlexanox to its effects on aphthous ulcers has not been established. After a single oral application of 100 mg of paste (5 mg Amlexanox), maximal serum levels are observed at 2.4 hours. Most of the systemic absorption of Amlexanox is via the gastrointestinal tract and the amount absorbed directly through the active ulcer is not a significant portion of the applied dose. The half-life for elimination was 3.5 +/- 1.1 hours in healthy individuals.
