The type II isobolographic analysis revealed that the combinations of levetiracetam with gabapentin for the fixed-ratios of 1:5 and 1:10 were supra-additive (synergistic; P<0.05) in terms of seizure suppression, while the combinations for the fixed-ratios of 1:1 and 1:2 were additive in the mouse 6 Hz psychomotor seizure model. We conclude that, as the combinations of levetiracetam with gabapentin for the fixed-ratios of 1:5 and 1:10 exerted supra-additive (synergistic) interaction in the mouse 6 Hz psychomotor seizure model, this may be considered as particularly favorable combinations in further clinical practice.
