LOTRISONE vs PEDIOTIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lotrisone combines betamethasone dipropionate, a corticosteroid that binds to glucocorticoid receptors, modulating gene expression to reduce inflammation, and clotrimazole, an imidazole antifungal that inhibits CYP51 (lanosterol 14alpha-demethylase), disrupting ergosterol synthesis and fungal cell membrane integrity.
PEDIOTIC contains hydrocortisone, neomycin, and polymyxin B. Neomycin and polymyxin B are antibiotics that inhibit bacterial protein synthesis and disrupt bacterial cell membrane integrity, respectively. Hydrocortisone is a corticosteroid that suppresses inflammation by inhibiting phospholipase A2, reducing prostaglandin and leukotriene synthesis.
Apply a thin film to affected skin areas twice daily, morning and evening, for 2 weeks.
Instill 4 drops into the affected ear(s) twice daily for 7-10 days.

Clotrimazole: 3.5-6 hours (topical, minimal systemic absorption); betamethasone dipropionate: approximately 4-6 hours for betamethasone after hydrolysis.
Not established for topical otic use; systemic absorption is minimal. If absorbed, terminal half-life of dexamethasone is approximately 3-4 hours.
Clotrimazole: <0.5% of dose excreted unchanged in urine; betamethasone dipropionate: primarily renal (<5% unchanged) and biliary/fecal (35-50% as metabolites).
Renal elimination of absorbed drug (primarily unchanged) accounts for <10% of topically applied dose; fecal/biliary routes negligible.
