TRINALIN vs ZADITOR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
TRINALIN is a combination of azatadine, a first-generation antihistamine that antagonizes histamine H1 receptors, and pseudoephedrine, a sympathomimetic amine that stimulates alpha-adrenergic receptors, causing vasoconstriction and reducing nasal congestion.
Selective histamine H1 receptor antagonist. Stabilizes mast cells, reducing release of histamine and other mediators of allergic response.
One tablet (azatadine 1 mg/pseudoephedrine 120 mg) orally every 12 hours. Not to exceed 2 tablets in 24 hours.
1 drop in each affected eye twice daily, approximately 6-8 hours apart.

Terminal elimination half-life approximately 20-30 hours; clinical context: allows twice-daily dosing for sustained decongestant effect
Terminal elimination half-life is approximately 7 hours in adults, which supports twice-daily dosing for sustained ocular effects.
Renal: 70-80% as unchanged drug and metabolites; biliary/fecal: 20-30%
Primarily renal excretion as unchanged drug (approximately 30-40% of dose) and biliary/fecal elimination of metabolites (60-70%).
