Summary

Nicardipine can inhibit P-glycoprotein, which transports fexofenadine out of cells and back into the gut lumen. Fexofenadine levels could rise modestly, but this is unlikely to be clinically important because of fexofenadine's wide therapeutic margin.

What this interaction means in plain words

Fexofenadine 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.

Fexofenadine belongs to Respiratory; Nicardipine belongs to Cardiovascular.

Evidence level: Low

Why it happens

Inhibition of intestinal P-glycoprotein efflux by nicardipine, increasing fexofenadine absorption.
