Professional:MONITOR: Coadministration with quinine or quinidine may decrease the renal clearance of amantadine. The proposed mechanism is quinine and quinidine inhibition of the renal tubular secretion of amantadine. In 18 healthy volunteers administered a single oral dose of amantadine (3 mg/kg), renal clearance of amantadine decreased by approximately 27% and 32% within 6 hours after ingestion of a 200 mg dose of quinine or quinidine, respectively. The interaction was reported only in the male subjects and was not influenced by age.
MANAGEMENT: The potential for increased pharmacologic effects of amantadine, including adverse effects such as dizziness, confusion, ataxia, orthostatic hypotension, dry mouth, nausea and constipation, should be considered during coadministration with quinine or quinidine.
