The effects of drugs on electrocardiograms in anesthetized normal Lewis and heart failure rats were evaluated. The effects of cisapride were investigated by administering three different dosages (8,16 and 24mg/kg) for the acute study and one dosage (24mg/kg/day) for the chronic study (for 7 days) in control and ailing rats. After the oral administration of mexiletine at 30mg/kg for 1 week, cisapride at 24mg/kg was administered to the rats with heart failure (n=15 in each). After chronic cisapride treatment for 7 days, the QT intervals in control and ailing rats were prolonged from 68.0±1.6 (mean±s.e.m.) to 74.0±2.4msec and from 77.6±1.9 to 88.8±2.3 msec, respectively (p<0.05 and p<0.01). A single dosage of cisapride at 8 or 16 mg/kg did not affect the QT interval in control rats. However, with a single dose of cisapride at 8,16 and 24mg/kg in rats with heart failure, the QT interval increased dose-dependently from 75.5±1.9 to 81.2±1.8msec, 76.4±1.6 to 87.8±2.5msec, and 78.4±2.1 to 101.4±1.2msec, respectively (each, p<0.01). After the administration of mexiletine, cisapride had no such effects. Cisapride prolonged the QT interval in rats with heart failure dose-dependently, while mexiletine prevented the effect. These results indicate that a high dose of cisapride should be used carefully during illness, but mexiletine may prevent a cisapride-induced long QT interval.","subitem_description_type":"Abstract"}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Niigata University School of
