CHILDREN'S CETIRIZINE HYDROCHLORIDE HIVES RELIEF vs PHENETRON
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.
Phenetron is an antihistamine that competes with histamine for H1-receptor sites, blocking histamine-mediated effects in the respiratory tract, vascular system, and gastrointestinal tract. It also exhibits anticholinergic and sedative properties.
5 mg or 10 mg orally once daily; maximum 10 mg per day.
Adults: 50 mg intramuscularly every 6 hours as needed.

Terminal elimination half-life is approximately 8.3 hours in healthy adults; prolonged to ~20 hours in renal impairment (CrCl <30 mL/min).
Terminal half-life 12–15 hours; clinically, steady-state achieved in ~3 days
Approximately 70% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 10% is eliminated in feces.
Renal: ~70% unchanged; Biliary/Fecal: ~15% as metabolites; 15% unidentified
