DESLORATADINE vs PROMETH PLAIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Desloratadine is a long-acting tricyclic histamine antagonist selective for the H1 receptor, inhibiting histamine release from mast cells and basophils. It reduces allergic inflammation by decreasing cytokine and chemokine release.
Antagonist at histamine H1 receptors; also exhibits anticholinergic, antiemetic, and sedative effects.
5 mg orally once daily.
12.5-25 mg intramuscularly or intravenously every 4-6 hours as needed; maximum 100 mg/day.

Terminal half-life 27 hours (range 21–30 h) in healthy adults; supports once-daily dosing.
Clinical Note
moderateDesloratadine + Venlafaxine
"The risk or severity of adverse effects can be increased when Desloratadine is combined with Venlafaxine."
Clinical Note
moderateDesloratadine + Nefazodone
"The risk or severity of adverse effects can be increased when Desloratadine is combined with Nefazodone."
Clinical Note
moderateDesloratadine + Stiripentol
"The risk or severity of adverse effects can be increased when Desloratadine is combined with Stiripentol."
Clinical Note
moderateTerminal elimination half-life is 10-14 hours in adults; may be prolonged in elderly or hepatic impairment.
Primarily renal (87% as metabolites, ~41% unchanged) and fecal (~9%). Metabolized to active 3-hydroxydesloratadine.
Primarily renal (approximately 70%) as metabolites and unchanged drug; biliary/fecal excretion accounts for ~20%.
