Theoretically, the concomitant administration of memantine and other drugs that undergo active renal tubular secretion may result in altered plasma levels of both drugs. The clinical significance is unknown. When hydrochlorothiazide/triamterene and memantine were coadministered in a clinical study, the bioavailability of hydrochlorothiazide decreased by 20% and there was no change in memantine or triamterene bioavailability.
