PEDIOTIC vs VASOCIDIN
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.
Vasocidin is a combination of sulfacetamide sodium, a sulfonamide antibiotic that inhibits bacterial dihydropteroate synthase, thereby blocking folate synthesis and bacterial growth, and prednisolone sodium phosphate, a corticosteroid that suppresses inflammation by inhibiting phospholipase A2 and subsequent prostaglandin and leukotriene synthesis.
Instill 4 drops into the affected ear(s) twice daily for 7-10 days.
One drop of the ophthalmic suspension into the conjunctival sac of the affected eye(s) every 4 hours while awake and at bedtime for 7 days; duration may be extended based on clinical response.

Not established for topical otic use; systemic absorption is minimal. If absorbed, terminal half-life of dexamethasone is approximately 3-4 hours.
Terminal elimination half-life is 6-8 hours in patients with normal renal function; prolonged in renal impairment.
Renal elimination of absorbed drug (primarily unchanged) accounts for <10% of topically applied dose; fecal/biliary routes negligible.
Renal: 70-80% as unchanged drug; biliary/fecal: 20-30% as metabolites and unchanged drug.
