HICON vs QBREXZA
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Unknown; possibly involves modulation of hypothalamic thermoregulatory center.
Selective D1 and D5 dopamine receptor antagonist; reduces dopamine-mediated vasodilation in choroidal blood vessels, decreasing choroidal thickness and neovascularization.
HICON (norepinephrine) 0.05-0.5 mcg/kg/min IV continuous infusion, titrated to blood pressure.
1 capsule (40 mg) orally twice daily with or without food.

Terminal half-life: 12-18 hours; prolonged to 24-36 hours in renal impairment (CrCl <30 mL/min)
Terminal elimination half-life is approximately 150 hours (range 120-200 hours), supporting once-daily dosing without significant accumulation.
Renal: 70% as unchanged drug; biliary/fecal: 25% as metabolites; 5% other
Renal: approximately 30% as unchanged drug; fecal: approximately 60% as metabolites and parent compound; biliary excretion contributes to fecal elimination.
