PURPOSE: Nausea and vomiting are among the major problems occurring during and after the chemotherapy treatments of cancer patients. The recently developed 5-HT(3) antagonists have proved much more effective than former agents. Several studies have shown that these agents cause certain ECG changes. We aimed to evaluate the ECG changes caused by palonosetron, one of the new 5-HT(3) antagonists.
METHODS: Our study includes a total of 50 patients diagnosed with solid-organ tumors receiving chemotherapy. The patients were applied 12-lead ECG before palonosetron infusion. Afterwards, subsequent ECGs were applied on the 30th, 60th, and 90th minutes following the infusion of palonosetron. Arterial blood pressure was measured before and after the infusion. PR, QRS, QT, QTmax, QTmin, QTd, Pmax, Pmin, Pd, QTc, QTcmax, QTcmin, and QTcd values were evaluated for each ECG.
RESULTS: We did not detect significant correlations between the systolic and diastolic blood pressures before and after (30 min) palonosetron infusion (p>0.05). However, there was a statistically significant decrease in heart rate (p = 0.000). The evaluation of ECG findings revealed that therewas a significant prolongation in PR distance, as shown by the comparisons of 0 min with 30, 60, and 90 min. On the other hand, there was no significant difference in QRS, QT, QTmax, QTmin, QTd, Pmax, Pmin, Pd, QTc, QTcmax, QTcmin, and QTcd values (p>0.05).
CONCLUSION: In this study, we revealed that palonosetron did not cause any severe rhythmic disorders or symptomatic ECG changes. We concluded that it could be safe to administer palonosetron antiemetically.

PURPOSE: The use of serotonin type 3 (5-HT3) receptor antagonists (RAs) in the prevention of nausea and vomiting caused by emetogenic chemotherapy is part of a comprehensive management strategy for patients undergoing chemotherapy. Electrocardiographic effects have been reported in patients after intravenous administration of 5-HT3 RAs. The present study investigated the electrocardiogram (ECG) profile of the 5-HT3 RA palonosetron following International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) E14 Guidelines.
METHODS: A total of 221 healthy subjects (101 females, 120 males) were randomized in this phase I, double-blind, double-dummy, parallel group study and assigned to one of five treatments: placebo, palonosetron (0.25, 0.75, or 2.25 mg), or moxifloxacin (400 mg). ECGs were recorded for 24 h pre-dosing until 48 h post-dose. The primary endpoint was the placebo time-matched and baseline-subtracted individual QTc interval prolongation (ΔΔQTcI).
RESULTS: The QTc interval was not prolonged after administration of palonosetron (ΔΔQTcI upper confidence interval was<10 ms for all time points in all palonosetron treatment groups). Assay sensitivity was confirmed with the expected change in the QTc interval after administration of the positive control moxifloxacin.
CONCLUSIONS: Palonosetron, even at supratherapeutic doses, has no effect on cardiac repolarization as measured by the QTc interval in a validated controlled clinical trial.
