ANUSOL HC vs APHTHASOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone, a corticosteroid, binds to glucocorticoid receptors, inhibiting phospholipase A2 activity and reducing prostaglandin and leukotriene synthesis. It also suppresses cytokine production and inflammatory cell migration, leading to decreased edema, erythema, and pruritus in anorectal tissues.
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.
Apply a thin layer to the affected area rectally 2 to 4 times daily, or after each bowel movement, for up to 7 days. Each application should not exceed 1 gram.
Adults: 5 mg orally three times daily for 5 days.

Terminal elimination half-life of hydrocortisone is approximately 1.5-2 hours (range 1-3 h) in adults; clinical effect outlasts half-life due to intracellular receptor-mediated action.
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.
Renal (primarily as metabolites) >80%; fecal ~15%; <2% unchanged in urine due to extensive hepatic metabolism. Biliary excretion is negligible.
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%.
