I'm always warned to take no drugs 14 hours before a drug test unless directed by a medical professional, and if a drug is taken, it must be reported before the test to the administrator. this sounds like a question that should be addressed to your Primary Care Provider.
I don't believe you should have any trouble, but I did find a site where you can get more information on those two PPI's (Proton Pump Inhibitors). http://www.netwellness.org/question.cfm/40941.htm
It is another .org site. That page was about Nexium and was answered by a pharmacy student. The site says it was posted in 2006, so that person is undoubtedly now a full-fledged pharmacist by now.
