raNITIdine memantine

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.

Drug and food interactions

Minor

raNITIdine food

Applies to: Acid Control 75 (ranitidine)

H2 antagonists may reduce the clearance of nicotine. Cimetidine, 600 mg given twice a day for two days, reduced clearance of an intravenous nicotine dose by 30%. Ranitidine, 300 mg given twice a day for two days, reduced clearance by 10%. The clinical significance of this interaction is not known. Patients should be monitored for increased nicotine effects when using the patches or gum for smoking cessation and dosage adjustments should be made as appropriate.
