Summary

Anastrozole is not a clinically meaningful CYP3A4 inhibitor, so a significant rise in cisapride exposure is not expected. Cisapride has a narrow margin because of QT prolongation, but no real interaction is established for this pair.

What this interaction means in plain words

Anastrozole and Cisapride have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.

Anastrozole belongs to Oncology; Cisapride belongs to Gastrointestinal Tract.

Evidence level: Low

Why it happens

Only weak in vitro CYP inhibition is described for anastrozole; no clinically relevant effect on cisapride metabolism is established.

What to do

No specific action is needed beyond the usual cisapride precautions. Monitor the ECG if other QT-prolonging risks exist.
