Minor

pantoprazole vandetanib

Applies to: Protonix IV (pantoprazole) and vandetanib

The use of vandetanib with proton pump inhibitors may theoretically reduce its gastrointestinal absorption. Vandetanib exhibits pH-dependent solubility, with increased solubility at lower pH. The clinical significance is unknown. In healthy subjects, no clinically significant changes in the Cmax and AUC of vandetanib occurred, after coadministration of a single dose of vandetanib with five daily doses of omeprazole, or after coadministration of a single dose of vandetanib and two doses of ranitidine 12 hours apart. Dose adjustments are not required when vandetanib is administered with omeprazole or ranitidine.
