CHILDREN'S CETIRIZINE HYDROCHLORIDE HIVES RELIEF vs TEMARIL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cetirizine is a selective histamine H1-receptor antagonist. It inhibits the H1 receptor, reducing histamine-mediated effects such as edema, flare, and pruritus.
Temaril (trimeprazine tartrate and prednisolone) combines an antipruritic phenothiazine antihistamine with a corticosteroid. Trimeprazine blocks histamine H1 receptors, reducing pruritus and allergic reactions. Prednisolone suppresses inflammation via glucocorticoid receptor activation, inhibiting phospholipase A2 and cytokine production.
5 mg or 10 mg orally once daily; maximum 10 mg per day.
2.5 mg orally twice daily or 5 mg orally at bedtime; maximum 10 mg/day.

Terminal elimination half-life is approximately 8.3 hours in healthy adults; prolonged to ~20 hours in renal impairment (CrCl <30 mL/min).
Terminal elimination half-life is 9–12 hours in adults; prolonged in hepatic impairment (up to 20 hours). Given TID dosing, steady state is reached within 2 days.
Approximately 70% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 10% is eliminated in feces.
Primarily via kidneys as metabolites; unchanged drug accounts for <1%. Biliary/fecal excretion is minor. Approx. 90% recovered in urine within 24 hours.
