BROMFED-DM vs CHILDREN'S MOTRIN COLD
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Brompheniramine is a first-generation alkylamine antihistamine that competitively antagonizes histamine at H1 receptors, reducing allergic symptoms. Pseudoephedrine is a sympathomimetic amine that directly stimulates alpha-adrenergic receptors, causing vasoconstriction and decongestion. Dextromethorphan is an NMDA receptor antagonist and sigma-1 receptor agonist that acts on the medullary cough center to suppress cough.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis. It provides analgesic, antipyretic, and anti-inflammatory effects. Pseudoephedrine is a sympathomimetic amine that directly stimulates alpha-adrenergic receptors in the respiratory tract mucosa, causing vasoconstriction and reducing nasal congestion.
1 capsule (brompheniramine maleate 6 mg, dextromethorphan HBr 30 mg) orally every 6 hours, not to exceed 4 capsules per 24 hours.
Adults and children ≥12 years: 20 mL (400 mg ibuprofen/30 mg pseudoephedrine) orally every 4-6 hours as needed; maximum 80 mL (1600 mg ibuprofen/120 mg pseudoephedrine) per day.

Brompheniramine: 24–36 h; pseudoephedrine: 5–8 h; dextromethorphan: 2–4 h (CYP2D6 extensive metabolizers) or up to 24 h (poor metabolizers).
Ibuprofen: 2-4 hours in children; pseudoephedrine: 5-8 hours (prolonged in alkaline urine). Clinical context: dosing intervals q6-8h for ibuprofen; pseudoephedrine accumulation possible with renal impairment.
Renal: 60–70% unchanged (brompheniramine); hepatic metabolism and renal excretion of metabolites (dextromethorphan: O-demethylation; pseudoephedrine: 70–90% unchanged in urine). Biliary/fecal: <5%.
Renal: ibuprofen ~90% as metabolites and conjugates, <10% unchanged; pseudoephedrine ~70-90% unchanged renally; urinary pH influences pseudoephedrine elimination (acidic urine increases excretion). Fecal: negligible.
