KOVANAZE vs VASOCIDIN
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.
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.
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.
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.

Terminal elimination half-life: approximately 7-9 hours following nasal administration; clinical significance: supports twice-daily dosing regimen
Terminal elimination half-life is 6-8 hours in patients with normal renal function; prolonged in renal impairment.
Renal excretion of unchanged drug: ~20-30%; fecal/biliary elimination: minimal (<5%); remainder as metabolites
Renal: 70-80% as unchanged drug; biliary/fecal: 20-30% as metabolites and unchanged drug.
