Professional:

Coadministration with erythromycin has been shown to increase the oral bioavailability of fexofenadine. The proposed mechanism is erythromycin inhibition of the intestinal efflux of fexofenadine via P-glycoprotein transporter. In addition, erythromycin may decrease biliary excretion of fexofenadine. In 24 healthy volunteers, coadministration of fexofenadine 120 mg twice a day and erythromycin 500 mg every 8 hours resulted in a 82% and 109% increase in the steady-state fexofenadine peak plasma concentration (Cmax) and systemic exposure (AUC), respectively, compared to administration of fexofenadine alone. However, no increase in adverse effects or QTc interval were noted. No studies have been performed using clarithromycin or troleandomycin, but similar results are possible given their similarities to erythromycin. Fexofenadine had no effect on the pharmacokinetics of erythromycin.
