DESLORATADINE AND PSEUDOEPHEDRINE SULFATE 24 HOUR vs WYAMINE SULFATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Desloratadine is a long-acting tricyclic histamine antagonist with selective H1-receptor histamine antagonist activity. Pseudoephedrine sulfate is an alpha-adrenergic receptor agonist causing vasoconstriction.
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.
One tablet (desloratadine 5 mg/pseudoephedrine sulfate 240 mg) orally once daily.
Intramuscular injection: 15-30 mg as a single dose; may repeat in 10-15 minutes if needed. Maximum total dose: 60 mg.

Desloratadine: 27 hours (terminal); pseudoephedrine sulfate: 5-8 hours (terminal, dependent on urine pH).
Terminal elimination half-life is 6-8 hours in adults with normal renal function (CrCl >90 mL/min).
Desloratadine: 41% urine (metabolites), 47% feces (metabolites); pseudoephedrine sulfate: 70-90% renal (unchanged), 1% biliary.
Primarily renal; 90% excreted unchanged in urine within 24 hours. Minimal biliary/fecal elimination (<5%).
