APHTHASOL vs WESTCORT
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Aphthasol (amlexanox) is an anti-inflammatory agent that inhibits the formation and release of inflammatory mediators such as histamine and leukotrienes from mast cells, neutrophils, and other inflammatory cells. It also inhibits the activation of eosinophils and neutrophils, and reduces cytokine production, thereby suppressing the immune response involved in aphthous ulcer formation.
Topical corticosteroid with anti-inflammatory, antipruritic, and vasoconstrictive actions. Binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine production.
Adults: 5 mg orally three times daily for 5 days.
Apply a thin film to affected area twice daily. Use for no longer than 2 consecutive weeks.

Terminal elimination half-life is 1.5 to 2.5 hours. This short half-life supports multiple daily dosing for local therapeutic effect with minimal systemic accumulation.
Terminal elimination half-life is 2-4 hours. Clinical context: Requires multiple daily applications for sustained effect; systemic accumulation unlikely with topical use.
Renal excretion of unchanged drug and metabolites accounts for approximately 50-60% of the administered dose, with the remainder eliminated via biliary/fecal routes as metabolites and unchanged drug. Biliary excretion constitutes about 20-30%.
Primarily renal (70-90% as metabolites, <5% unchanged); minor biliary/fecal (10-20%)
