CYP2D6 fremmere og hæmmere: i en populations- farmakokinetisk analyse er det blevet vist, at der ikke var nogen signifikant virkning på palonosetrons clearance, når det blev givet sammen med CYP2D6 fremmere (dexamethason og rifampicin) og hæmmere (herunder amiodaron, celecoxib, chlorpromazin, cimetidin, doxorubicin, fluoxetin, haloperidol, paroxetin, quinidin, ranitidin, ritonavir, sertralin eller terbinafin).
CYP2D6 inducers and inhibitors: in a population pharmacokinetic analysis, it has been shown that there was no significant effect on palonosetron clearance when co-administered with CYP2D6 inducers (dexamethasone and rifampicin) and inhibitors (including amiodarone, celecoxib, chlorpromazine, cimetidine, doxorubicin, fluoxetine, haloperidol, paroxetine, quinidine, ranitidine, ritonavir, sertraline or terbinafine).
