CHILDREN'S CLARITIN vs LORATADINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Loratadine is a long-acting second-generation antihistamine that selectively antagonizes peripheral histamine H1 receptors, thereby inhibiting the effects of histamine released from mast cells and basophils, reducing allergic symptoms.
Loratadine is a long-acting tricyclic antihistamine with selective peripheral H1-receptor antagonist activity. It inhibits histamine-induced vasodilation and bronchoconstriction.

The terminal elimination half-life of loratadine is 8-14 hours (mean 11 hours) in healthy adults; for the active metabolite descarboethoxyloratadine, half-life is 17-24 hours (mean 20 hours). This supports once-daily dosing.
Clinical Note
moderateLoratadine + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Loratadine is combined with Fluticasone propionate."
Clinical Note
moderateLoratadine + Teriflunomide
"The metabolism of Teriflunomide can be decreased when combined with Loratadine."
Clinical Note
moderateLoratadine + Haloperidol
"The metabolism of Haloperidol can be decreased when combined with Loratadine."
Clinical Note
moderateLoratadine + Sulfisoxazole
Loratadine: 8-14 hours (mean ~10 hours). Active metabolite descarboethoxyloratadine: 17-24 hours (mean ~20 hours). Clinically, duration supports once-daily dosing.
Loratadine is primarily eliminated via hepatic metabolism, with approximately 80% of the dose excreted as metabolites in urine (40%) and feces (40%). Less than 1% is excreted unchanged in urine.
Approximately 40% excreted in urine as metabolites (primarily descarboethoxyloratadine) and 40% in feces as metabolites; <1% excreted unchanged.
