Siden zoledronsyre ikke metaboliseres i mennesker og stoffet havde lille eller ingen effekt som direkte virkende og/ eller irreversibel metabolismeafhængig hæmmer af P450 enzymer, er det usandsynligt, at zoledronsyre reducerer den metaboliske udskillelse af stoffer, som metaboliseres af cytokrom P450 enzymsystemet.
Since zoledronic acid is not metabolised in humans and the substance was found to have little or no capacity as a direct- acting and/ or irreversible metabolism-dependent inhibitor of P450 enzymes, zoledronic acid is unlikely to reduce the metabolic clearance of substances which are metabolised via the cytochrome P450 enzyme systems.
