CLARITIN vs CYPROHEPTADINE HYDROCHLORIDE
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.
Cyproheptadine is a potent antihistamine (H1 receptor antagonist) and antiserotonergic agent (5-HT2 receptor antagonist). It also exhibits weak anticholinergic and sedative properties. It blocks histamine-mediated vasodilation, increased capillary permeability, and pruritus, as well as serotonin-mediated effects on appetite and mood.

Terminal elimination half-life 27 hours (range 22-30 hours); clinical context: allows once-daily dosing, steady state reached in 5-7 days
Terminal half-life approximately 8–16 hours in adults; may be prolonged in elderly or hepatic impairment.
Renal 40% as metabolites, fecal 40% as metabolites, biliary <5% as unchanged drug
Primarily renal (appreciable unchanged drug and metabolites); biliary/fecal elimination minor (<5%).
