KOVANAZE vs LORATADINE REDIDOSE
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.
Selective peripheral H1 receptor antagonist; inhibits histamine release from mast cells.
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.
10 mg orally once daily

Terminal elimination half-life: approximately 7-9 hours following nasal administration; clinical significance: supports twice-daily dosing regimen
Terminal elimination half-life is 8–14 hours (mean ~12 hours) for desloratadine (active metabolite); parent loratadine half-life ~3–20 hours (mean ~8 hours). Clinically, once-daily dosing maintains steady state in 5–7 days.
Renal excretion of unchanged drug: ~20-30%; fecal/biliary elimination: minimal (<5%); remainder as metabolites
Renal (approximately 40% as metabolites), biliary/fecal (approximately 60% as metabolites). Less than 1% excreted unchanged in urine.
