Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antihistamine (H1-receptor antagonist) with anticholinergic and sedative properties.
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.

Terminal elimination half-life 12-15 hours in adults; prolonged to 20-30 hours in hepatic impairment.
Terminal elimination half-life 27 hours (range 22-30 hours); clinical context: allows once-daily dosing, steady state reached in 5-7 days
Primarily renal (70-80% as metabolites, 20-30% unchanged); biliary/fecal excretion accounts for 15-20%.
Renal 40% as metabolites, fecal 40% as metabolites, biliary <5% as unchanged drug
