EMERPHED vs IBUPROFEN AND PSEUDOEPHEDRINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
EMERPHED is a combination of ephedrine and phenylephrine. Ephedrine is a sympathomimetic amine that acts directly on alpha and beta adrenergic receptors and indirectly by releasing norepinephrine from nerve endings, causing vasoconstriction, bronchodilation, and increased heart rate and blood pressure. Phenylephrine is a selective alpha-1 adrenergic receptor agonist causing vasoconstriction and increased blood pressure.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and alleviating pain, fever, and inflammation. Pseudoephedrine is a sympathomimetic amine that acts as an alpha-1 adrenergic receptor agonist, causing vasoconstriction in nasal mucosa and reducing congestion.
Adults: 1-2 capsules (25-50 mg ephedrine sulfate) orally every 3-4 hours as needed, not to exceed 150 mg in 24 hours.
1 tablet (ibuprofen 200 mg/pseudoephedrine HCl 30 mg) orally every 4-6 hours as needed; maximum ibuprofen 1200 mg/day, pseudoephedrine 120 mg/day. Do not exceed 6 tablets in 24 hours.

Terminal elimination half-life: 3-6 hours (prolonged in renal impairment: up to 15 hours).
Ibuprofen: 2-4 hours (terminal half-life); pseudoephedrine: 4-6 hours (terminal half-life, prolonged in alkaline urine up to 16 hours).
Renal excretion of unchanged drug (~30-50%) and metabolites; minor biliary/fecal elimination (<10%).
Ibuprofen: renal elimination of conjugated metabolites (90%) and unchanged drug (10%); <5% biliary. Pseudoephedrine: renal elimination of unchanged drug (70-90%) and metabolites (10-30%).
