Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Loratadine is a long-acting tricyclic antihistamine with selective peripheral H1 receptor antagonistic activity. It inhibits histamine release from mast cells and reduces allergic responses.
Levocabastine is a selective histamine H1-receptor antagonist, inhibiting histamine release from mast cells and basophils.

Terminal elimination half-life 27 hours (range 22-30 hours); clinical context: allows once-daily dosing, steady state reached in 5-7 days
Terminal elimination half-life in adults: 35-40 hours; clinical context: supports once-daily dosing, with steady-state reached after approximately 7 days
Renal 40% as metabolites, fecal 40% as metabolites, biliary <5% as unchanged drug
Renal excretion as unchanged drug and metabolites: ~70% (48% unchanged, 9% as levocabastine glucuronide, 13% as other metabolites); fecal excretion: ~20%
