Sex: male

Endpoint: EC50

Effect level: > 17 % v/v

Remarks: No cardiac effects noted at the highest exposure concentration.

Mortality: None

Clinical signs: Various observations included in tables in study report (see attached) but no clinical signs exclusively recorded. ECG results were analyzed for cardiac sensitization determination.

Interpretation of results: relatively harmless

Applicant's summary and conclusion

Cardiac Sensitization EC50 > 17.0%.
Executive summary:

This study was designed to assess the cardiac sensitization potential of the test article in beagle dogs. Adrenaline was administered by intravenous injection before and during inhalation of the test article. The effect of the adrenaline on the ECG pattern was examined. Positive evidence of cardiac sensitization would be observed as the presence of multiple multifocal ectopic beats of ventricular fibrillation following adrenaline administration during inhalation of the test substance. No such effect should be observed in the absence of the test substance. The test article was administered at concentrations of 5, 10, and 17% v/v. There was no evidence of cardiac sensitization at any dose level.
