DRUG INTERACTIONS

Coadministration of TRITEC (ranitidine bismuth citrate) with clarithromycin resulted in increased plasma ranitidine concentrations (57%), increased plasma bismuth trough concentrations (48%), and increased 14- hydroxy- clarithromycin plasma concentrations (31%). Coadministration with aspirin results in a slight decrease in the rate of salicylate absorption that is clinically unimportant. Coadministration with a high dose of antacid (170 mEq) results in a 28% decrease in plasma concentrations of ranitidine and may decrease plasma concentrations of bismuth from TRITEC (ranitidine bismuth citrate) . These effects are clinically insignificant.

For information on drug interactions associated with ranitidine, refer to the ZANTAC ® package insert.
