DISOMER vs DRIXORAL PLUS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective dopamine D2 receptor antagonist; also blocks alpha-1 adrenergic, histamine H1, and muscarinic M1 receptors.
DRIXORAL PLUS contains dexbrompheniramine, an antihistamine that competes with histamine for H1-receptor sites, suppressing histamine-induced symptoms; and pseudoephedrine, a sympathomimetic amine that directly acts on alpha-adrenergic receptors in the respiratory tract mucosa, causing vasoconstriction and reducing nasal congestion.
Adults: 1 mg orally once daily.
1 tablet orally every 12 hours, not to exceed 2 tablets in 24 hours.

12–15 hours in adults with normal renal function; prolonged to 30–40 hours in severe renal impairment (CrCl <30 mL/min).
Pseudoephedrine: ~9-16 hours (pH-dependent, longer in alkaline urine). Dexbrompheniramine: ~20-25 hours. Clinical context: multiple dosing accumulates.
Renal: 80% as unchanged drug; biliary/fecal: 15% as metabolites; <5% unchanged in feces.
Renal: 50-70% unchanged for pseudoephedrine; hepatic metabolism for dexbrompheniramine with renal excretion of metabolites.
