Cisapride must be used with caution due to reports of drug-induced arrhythmias and long QT syndrome. Although this drug was originally given marketing approval by the US FDA in 1993, all registered formulations have since been discontinued. In the EU (since 2002) conditions of use have been applied to active marketing authorisations for cisapride containing medicinal products.
