PEDIOTIC vs STATROL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Statrol is a combination antibiotic ointment containing polymyxin B sulfate, neomycin sulfate, and gramicidin. Polymyxin B binds to lipopolysaccharides in the outer membrane of gram-negative bacteria, disrupting membrane integrity. Neomycin inhibits protein synthesis by binding to the 30S ribosomal subunit. Gramicidin alters cell membrane permeability in gram-positive bacteria by forming ion channels.

Not established for topical otic use; systemic absorption is minimal. If absorbed, terminal half-life of dexamethasone is approximately 3-4 hours.
Terminal half-life 12-16 hours in adults; prolonged to 24-30 hours in severe renal impairment (CrCl <30 mL/min).
Renal elimination of absorbed drug (primarily unchanged) accounts for <10% of topically applied dose; fecal/biliary routes negligible.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites, 10% unchanged.
