KOVANAZE vs PEDIOTIC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
KOVANAZE (norepinephrine and phenylephrine) is a combination of two vasopressors: norepinephrine, an α1-adrenergic receptor agonist with β1-adrenergic activity, and phenylephrine, a selective α1-adrenergic receptor agonist. Both agents cause vasoconstriction and increase blood pressure via activation of α1-adrenergic receptors on vascular smooth muscle.
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.
Intravenous bolus of 1 mg/kg over 10 minutes, followed by intravenous infusion of 0.02 mg/kg/min for 4 hours, then 0.01 mg/kg/min for 20 hours.
Instill 4 drops into the affected ear(s) twice daily for 7-10 days.

Terminal elimination half-life: approximately 7-9 hours following nasal administration; clinical significance: supports twice-daily dosing regimen
Not established for topical otic use; systemic absorption is minimal. If absorbed, terminal half-life of dexamethasone is approximately 3-4 hours.
Renal excretion of unchanged drug: ~20-30%; fecal/biliary elimination: minimal (<5%); remainder as metabolites
Renal elimination of absorbed drug (primarily unchanged) accounts for <10% of topically applied dose; fecal/biliary routes negligible.
