CHILDREN'S CETIRIZINE HYDROCHLORIDE HIVES RELIEF vs DECABID
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.
Decabid is a combination of chlorpheniramine (antihistamine) and pseudoephedrine (decongestant). Chlorpheniramine competitively antagonizes histamine at H1 receptors, reducing allergic symptoms. Pseudoephedrine acts as a sympathomimetic agent, stimulating alpha-adrenergic receptors to cause vasoconstriction, reducing nasal congestion.
5 mg or 10 mg orally once daily; maximum 10 mg per day.
1 capsule orally every 12 hours; each capsule contains 10 mg phenylephrine hydrochloride and 75 mg carbinoxamine maleate.

Terminal elimination half-life is approximately 8.3 hours in healthy adults; prolonged to ~20 hours in renal impairment (CrCl <30 mL/min).
12 hours (terminal); prolonged to 24 hours in renal impairment (CrCl <30 mL/min)
Approximately 70% of the dose is excreted unchanged in urine via glomerular filtration and tubular secretion; about 10% is eliminated in feces.
Renal (50% as unchanged drug), fecal (40% as metabolites), biliary (10% as glucuronide conjugates)
