KOVANAZE vs OLOPATADINE HYDROCHLORIDE
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.
Olopatadine hydrochloride is a selective histamine H1 receptor antagonist and mast cell stabilizer. It inhibits histamine release from mast cells and prevents histamine-induced effects such as increased vascular permeability and pruritus.
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 0.1% or 0.2% ophthalmic solution in each affected eye twice daily (every 6-8 hours) for 0.1%; once daily for 0.2%.
