Objectives

Narrative objectives1

Recent research have showm that coadministration of proton pump inhibitor (PPI) could reduce the efficacy of capecitabine. However,underlying mechanisms of the interaction between capecitabine and PPI ramain unclear. One possibility is the alteration of capecitabine pharmacokinetics by the coadministration of rabeprazole. This prospective study analyzes the effects of rabeplazole on the pharmacokinetics of capecitabine and its active metabolites.
