|12 dogs with poorly controlled primary epilepsy were included in this prospective non-comparative study. Oral zonisamide dose was adapted to the desired effective blood levels (10 to 40 ug/dl). The mean dose required was 8,9 mg/kg every 12 hours.
Seven dogs showed a favourable response with a mean reduction of the seizures of 81,3%. Five dogs unfortunately even showed an increased seizure frequency.
Mild side effects like transient sedation, vomiting and diarrhea were seen in 6 (50%) of the treated animals.
