Summary
Crofelemer is minimally absorbed but may inhibit CYP3A4 locally in the gut wall. This could modestly raise nicardipine exposure and cause excess vasodilation, such as hypotension, flushing or edema. Systemic effects are unlikely, so clinical significance is probably small.
What this interaction means in plain words
Crofelemer and Nicardipine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Crofelemer belongs to Gastrointestinal Tract; Nicardipine belongs to Cardiovascular.
Why it happens
Possible inhibition of intestinal CYP3A4 by crofelemer reduces first-pass metabolism of nicardipine.
What to do
No empiric dose change is needed; check blood pressure and heart rate if the patient reports dizziness or edema after crofelemer is started.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
