KOVANAZE vs LEVOCETIRIZINE DIHYDROCHLORIDE
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.
Levocetirizine is a selective antagonist of peripheral histamine H1 receptors, blocking histamine-induced allergic responses by inhibiting H1 receptor activation in the gastrointestinal tract, blood vessels, and respiratory tract.
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.
5 mg orally once daily in the evening.

Terminal elimination half-life: approximately 7-9 hours following nasal administration; clinical significance: supports twice-daily dosing regimen
Terminal elimination half-life: 7-11 hours in adults. Clinically, this supports once-daily dosing; may be prolonged in renal impairment (creatinine clearance <30 mL/min).
Renal excretion of unchanged drug: ~20-30%; fecal/biliary elimination: minimal (<5%); remainder as metabolites
Renal: 85% as unchanged drug (70%) and metabolites (15%); fecal: 13%; biliary: minimal (<2%).
