BROMPHENIRAMINE MALEATE vs TRIPROLIDINE AND PSEUDOEPHEDRINE
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.
Triprolidine is a first-generation antihistamine that antagonizes histamine H1 receptors, reducing histamine-mediated allergic symptoms. Pseudoephedrine is a sympathomimetic amine that acts as a decongestant by stimulating alpha-adrenergic receptors in the respiratory tract mucosa, causing vasoconstriction and decreased nasal congestion.
4 mg orally every 4-6 hours, not to exceed 24 mg/day. Alternatively, extended-release: 12 mg every 12 hours.
1 tablet (2.5 mg triprolidine/60 mg pseudoephedrine) orally every 4-6 hours; max 4 tablets/24 hours.

Terminal half-life 22-25 hours; prolonged in hepatic impairment or elderly (up to 40 hours).
Triprolidine: 2-4 hours (parent compound). Pseudoephedrine: 4-8 hours, prolonged in alkaline urine (up to 16-24 hours).
Renal (85-90% as metabolites, 5-10% unchanged); biliary/fecal <5%.
Triprolidine: renal, 70% unchanged and metabolites. Pseudoephedrine: renal, 90% unchanged.
