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.
Hydrocortisone (topical) binds to glucocorticoid receptors, activating anti-inflammatory proteins and inhibiting phospholipase A2, thereby reducing prostaglandin and leukotriene synthesis.
Adults: 5 mg orally three times daily for 5 days.
Topical: Apply cream or ointment to affected area 2-4 times daily. Limit treatment area to less than 50% of body surface area. Maximum duration: 2 weeks unless directed by physician.

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.
30–60 minutes (terminal elimination half-life; short duration requires frequent dosing)
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%.
