Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective dopamine D2 receptor antagonist; also blocks alpha-1 adrenergic, histamine H1, and muscarinic M1 receptors.
ZERVIATE (cetirizine ophthalmic solution) contains cetirizine, a selective histamine H1 receptor antagonist. It inhibits histamine-induced vasodilation and increased vascular permeability, leading to reduction of ocular itching associated with allergic conjunctivitis.
Adults: 1 mg orally once daily.
1 drop in each affected eye twice daily (approximately 8 hours apart).

12–15 hours in adults with normal renal function; prolonged to 30–40 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is approximately 3 hours; clinical context: supports twice-daily topical ocular dosing for allergic conjunctivitis.
Renal: 80% as unchanged drug; biliary/fecal: 15% as metabolites; <5% unchanged in feces.
Primarily renal excretion of unchanged drug (approximately 70%) and metabolites; biliary/fecal elimination accounts for less than 20%.
