- Housing: 5 animals of the same sex per cage in Macrolon cages type III
- Diet: Ssnif-R Alleindiät, pellets
- Water: drinking water supplied in drinking bottles, ad libitum
- Acclimation period: at least 7 days

ENVIRONMENTAL CONDITIONS
- Temperature (°C): 21 ± 2 °C
- Humidity (%): 50 – 85 %

VEHICLE
- Concentration in vehicle: 50%

Doses:

2000 mg/kg bw

No. of animals per sex per dose:

5

Control animals:

other: not required

Details on study design:

- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: The animals were examined for clinical signs at the following time point after administration: 10 min, 1 h, 2 h, 6 h, 24 h, and thereafter once daily up to day 14. Individual body weights were determined weekly: on days 0 (before treatment), 7 and 14 (termination)
