BROMPHENIRAMINE MALEATE vs Cetirizine
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of histamine at H1 receptor sites, suppressing histamine-induced vasodilation, increased capillary permeability, and bronchoconstriction.
Cetirizine is a selective second-generation H1-receptor antagonist that inhibits histamine release from mast cells and basophils, thereby reducing allergic symptoms.
4 mg orally every 4-6 hours, not to exceed 24 mg/day. Alternatively, extended-release: 12 mg every 12 hours.
10 mg orally once daily; 5 mg orally once daily for mild symptoms

Terminal half-life 22-25 hours; prolonged in hepatic impairment or elderly (up to 40 hours).
Clinical Note
moderateCetirizine + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Cetirizine is combined with Fluticasone propionate."
Clinical Note
moderateLevocetirizine + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Levocetirizine."
Clinical Note
moderateLevocetirizine + Erythromycin
"The metabolism of Erythromycin can be decreased when combined with Levocetirizine."
Clinical Note
moderateLevocetirizine + Cyclosporine
Terminal elimination half-life is approximately 8.3 hours in healthy adults; extended to 20 hours in elderly and patients with renal impairment
Renal (85-90% as metabolites, 5-10% unchanged); biliary/fecal <5%.
Primarily renal (60% unchanged in urine); minor biliary/fecal (10%)
