ibuprofen: non-selective COX-1/COX-2 inhibitor reducing prostaglandin synthesis; phenylephrine: alpha-1 adrenergic receptor agonist causing vasoconstriction
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and thereby decreasing inflammation, pain, and fever.
1 tablet (ibuprofen 200 mg / phenylephrine 10 mg) orally every 4 hours while symptoms persist, not to exceed 6 tablets in 24 hours.
IV: 10 mg/kg over 15 minutes, followed by 5 mg/kg at 24, 48, and 72 hours after the first dose.

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 approximately 2.5 to 4 hours in adults. In preterm neonates (target population for Neoprofen), half-life is prolonged due to immature renal function: mean 30.5 hours (range 20–50 hours) after first dose, decreasing to ~15 hours after third dose. Clinical relevance: requires careful dosing intervals in neonates to avoid accumulation.
Renal: ~90% as unchanged drug and metabolites (ibuprofen: <10% unchanged, pseudoephedrine: 43-96% unchanged). Biliary/fecal: minimal (<5%).
Ibuprofen is primarily excreted renally as metabolites (approximately 90% of the dose), with less than 1% excreted unchanged. A small fraction (≤10%) is eliminated via bile/feces. For Neoprofen (ibuprofen lysine specifically used for patent ductus arteriosus), renal excretion accounts for >90% of elimination, predominantly as glucuronide conjugates and hydroxylated metabolites.
