CHILDREN'S CETIRIZINE HYDROCHLORIDE HIVES RELIEF vs DEXCHLORPHENIRAMINE MALEATE
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.
Dexchlorpheniramine maleate is a histamine H1 receptor antagonist that competitively blocks the effects of histamine at peripheral H1 receptors, reducing symptoms of allergic reactions such as vasodilation, increased vascular permeability, and smooth muscle contraction. It also has anticholinergic and sedative properties.
5 mg or 10 mg orally once daily; maximum 10 mg per day.

Terminal elimination half-life is approximately 8.3 hours in healthy adults; prolonged to ~20 hours in renal impairment (CrCl <30 mL/min).
Clinical Note
moderateDexchlorpheniramine maleate + Haloperidol
"The metabolism of Haloperidol can be decreased when combined with Dexchlorpheniramine maleate."
Clinical Note
moderateDexchlorpheniramine maleate + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Dexchlorpheniramine maleate."
Clinical Note
moderateDexchlorpheniramine maleate + Erythromycin
"The metabolism of Erythromycin can be decreased when combined with Dexchlorpheniramine maleate."
Clinical Note
moderateTerminal elimination half-life is 20-24 hours in healthy adults, allowing once or twice daily dosing. Prolonged in hepatic impairment or elderly.
Approximately 70% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 10% is eliminated in feces.
Primarily renal (approximately 70-80% as unchanged drug and metabolites, mainly glucuronide conjugates); minor biliary/fecal elimination (20-30%).
