title: Metabolism of benzydamine.
abstract: After an oral dose of 50 mg benzydamine to three volunteers, urinary metabolites were identified by mass spectrometric techniques. 50-65% of the dose was excreted unchanged with the urine. The main metabolic pathways were elimination of the dimethylaminopropyl group, elimination of the benzyl group, desmethylation, N-oxidation, and hydroxylation of the benzene ring. Didesmethylbenzydamine and hydroxybenzydamine were excreted in form of their corresponding glucuronides.
