Summary
Fosaprepitant is converted to aprepitant, which is a moderate CYP3A4 inhibitor and may modestly raise amlodipine exposure. This may enhance blood pressure lowering or cause peripheral edema, though a single dose of fosaprepitant is unlikely to have much effect.
What this interaction means in plain words
Amlodipine-perindopril and Fosaprepitant have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Amlodipine-perindopril belongs to Cardiovascular; Fosaprepitant belongs to Gastrointestinal Tract.
Why it happens
Aprepitant, the active metabolite of fosaprepitant, weakly to moderately inhibits CYP3A4-mediated amlodipine metabolism.
What to do
No routine dose change is needed; check blood pressure and watch for dizziness or edema around chemotherapy cycles.
