IBUPROFEN AND PSEUDOEPHEDRINE HYDROCHLORIDE vs WYAMINE SULFATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Wyamine sulfate (mephentermine sulfate) is a sympathomimetic amine that acts primarily by releasing norepinephrine from presynaptic nerve terminals, with direct alpha- and beta-adrenergic receptor agonist activity. It causes vasoconstriction and positive inotropic effects, increasing cardiac output and blood pressure.
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.
Intramuscular injection: 15-30 mg as a single dose; may repeat in 10-15 minutes if needed. Maximum total dose: 60 mg.

Ibuprofen: 2-4 hours (terminal half-life); pseudoephedrine: 4-6 hours (terminal half-life, prolonged in alkaline urine up to 16 hours).
Terminal elimination half-life is 6-8 hours in adults with normal renal function (CrCl >90 mL/min).
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%).
Primarily renal; 90% excreted unchanged in urine within 24 hours. Minimal biliary/fecal elimination (<5%).
