Due to prokinetic effects in the colon, abdominal cramps and diarrhea occur in up to 15% of patients taking cisapride however significant problems are unusual. In addition, cisapride is metabolized by the hepatic cytochrome P450 CYP3 A4 enzyme. When coadministered with drugs that inhibit this enzyme (such as ketoconazole, fluconazole, macrolide antibiotics, and HIV protease inhibitors), significant increases in serum levels of cisapride may occur that rarely lead to QT prolongation on the ECG and serious cardiac arrhythmias. For this reason, cisapride was removed...
