ADVIL CONGESTION RELIEF vs DISOPHROL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ibuprofen: non-selective COX-1/COX-2 inhibitor reducing prostaglandin synthesis; phenylephrine: alpha-1 adrenergic receptor agonist causing vasoconstriction
Disophrol is a combination of dexbrompheniramine, a first-generation antihistamine that blocks H1 receptors, and pseudoephedrine, a sympathomimetic amine that stimulates alpha-adrenergic receptors causing vasoconstriction.
1 tablet (ibuprofen 200 mg / phenylephrine 10 mg) orally every 4 hours while symptoms persist, not to exceed 6 tablets in 24 hours.
1 tablet (6 mg dexbrompheniramine maleate / 60 mg pseudoephedrine sulfate) orally every 4-6 hours; not to exceed 4 tablets in 24 hours.

Ibuprofen: 2-4 hours (short half-life requires frequent dosing). Pseudoephedrine: 5-8 hours (longer in alkaline urine). Context: Half-life prolonged in renal impairment.
Terminal elimination half-life is 3-4 hours in adults; in renal impairment, half-life may be prolonged up to 8-12 hours requiring dose adjustment.
Renal: ~90% as unchanged drug and metabolites (ibuprofen: <10% unchanged, pseudoephedrine: 43-96% unchanged). Biliary/fecal: minimal (<5%).
Renal excretion of unchanged drug and metabolites; approximately 60-70% of a dose eliminated in urine as unchanged drug and glucuronide conjugates, with <10% in feces.
