APHTHASOL vs POHERDY
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.
POHERDY is a monoclonal antibody targeting the human epidermal growth factor receptor 2 (HER2), binding to domain IV of the extracellular segment, thereby inhibiting ligand-independent HER2 signaling and mediating antibody-dependent cellular cytotoxicity (ADCC).
Adults: 5 mg orally three times daily for 5 days.
POHERDY: No approved drug. No dosing available.

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 half-life 12–18 hours (mean 15 h); requires dose adjustment in renal impairment (CrCl <30 mL/min)
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%.
Renal: 60% unchanged; fecal/biliary: 30%; 10% metabolized
